PRELIMINARY PROSPECTUS

American Depositary Shares
representing           Ordinary Shares
$           per American Depositary Share

___________________

We are offering            American depositary shares, or ADSs, in the United States, representing          ordinary shares of Incannex Healthcare Limited (“Incannex” or the “Company”). Each ADS represents 50 ordinary shares, no par value, deposited with Deutsche Bank Trust Company Americas, as depositary.

The offering is being underwritten on a firm commitment basis. We have granted the underwriter an option to buy up to an additional            ADSs to cover over-allotments. The underwriter may exercise this option at any time and from time to time during the 30-day period from the date of this prospectus.

Prior to this offering, there has been no public market for the ADSs. We have applied to list the ADSs on the Nasdaq Capital Market under the symbol “IXHL”.

Our ordinary shares are listed on the Australian Securities Exchange under the symbol “IHL.” On           , 2021, the last reported sale price of our ordinary shares on the Australian Securities Exchange was A$           per ordinary share, equivalent to a price of US$           per ADS, after giving effect to the Australian dollar/U.S. dollar exchange rate        of as of           , 2021, and an ADS-to-ordinary share ratio of 1 to 50.

The final offering price per ADS in U.S. dollars will be determined through negotiations between us and the representatives of the underwriter and will be based, in part, on prevailing market prices of our ordinary shares on the Australian Securities Exchange, after taking into account market conditions and other factors. For a discussion of the other factors considered in determining the final offering price per ADS, see “Underwriting.”

____________

(1)      In addition, we have agreed to reimburse the underwriter for certain expenses. See “Underwriting” on page 115 of this prospectus for additional information.

Investing in our securities involves a high degree of risk. See the section entitled “Risk Factors” appearing on pages 9 of this prospectus and elsewhere in this prospectus and the accompanying base prospectus for a discussion of information that should be considered in connection with an investment in our securities.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

The underwriter expects to deliver the ADSs to purchasers on or about           , 2021 through the book-entry facilities of The Depository Trust Company.

Risk Factors

Investing in the ADSs involves a high degree of risk. You should consider and read carefully all of the risks and uncertainties described below, as well as other information included in this prospectus, including our consolidated financial statements and related notes included elsewhere in this prospectus, before making an investment decision. If any of the following risks actually occur, it could harm our business, prospects, results of operations and financial condition. In such event, the trading price of the ADSs could decline and you might lose all or part of your investment.

Risks Related to Our Business

We have a history of operating losses and may not achieve or maintain profitability in the future.

We have experienced significant recurring operating losses and negative cash flows from operating activities since inception. For example, for the years ended June 30, 2020 and 2019, we had net losses of approximately A$4.7 million and approximately A$2.7 million, respectively, and approximately A$2.9 million and approximately A$2.2 million for the six months ended December 31, 2020 and 2019, respectively. As of December 31, 2020, we had accumulated losses of approximately A$35.4 million.

We are a clinical stage pharmaceutical development company and the success of our drug candidates is therefore uncertain. We focus on medicinal synthetic cannabinidiol pharmaceutical products and psychedelic medicine therapies.

We expect to continue to incur losses from operations for the foreseeable future and expect the costs of drug development to increase in the future as more patients are recruited to the clinical trials. In particular, we expect to continue to incur significant losses in the development of our clinical trials and drug candidates. Because of the numerous risks and uncertainties associated with the development, manufacturing, sales and marketing of our drug candidates, we may experience larger than expected future losses and may never become profitable.

Moreover, there is a substantial risk that we, or our development partners, may not be able to complete the development of our current drug candidates or develop other pharmaceutical products. It is possible that none of them will be successfully commercialized, which would prevent us from ever achieving profitability.

The increase in expenses may adversely impact our business if our sources of funding and revenue are insufficient.

We anticipate that as the costs related to the development of our clinical trials will increase, we will require additional funds to achieve our long-term goals of commercialization and further development of our drug candidates. In addition, we will require funds to pursue regulatory applications, defend intellectual property rights, contract manufacturing capacity, potentially develop marketing and sales capability and fund operating expenses. We intend to seek such additional funding through public or private financings and/or through licensing of our assets or other arrangements with corporate partners. However, such financing, licensing opportunities or other arrangements may not be available from any sources on acceptable terms, or at all. Any shortfall in funding could result in us having to curtail or cease our research and development activities, thereby harming our business, financial condition and results of operations.

In addition, because of the numerous risks and uncertainties associated with the development of our drug candidates, we are unable to predict the timing or amount of increased expenses, or when, or if, we will be able to achieve or maintain profitability. Our expenses could significantly increase beyond current expectations if the applicable regulatory authorities require further studies in addition to those currently anticipated. In any case, even if our drug candidates are approved for commercial sale, we anticipate incurring significant costs associated with the commercial launch of such drug candidates and there can be no guarantee that we will ever generate significant revenues.

We currently have no source of product revenue and may never become profitable.

Our drug candidates have not been approved for commercial sale, and we expect it to be several years before they are approved, if ever, and we are able to commence sales of our drug candidates. To date, we have not generated any revenue from the licensing or commercialization of our drug candidates and do not expect to receive revenue

from them for a number of years, if ever. We will not be able to generate product revenue unless and until our current drug candidates or any future drug candidates, alone or with future partners, successfully completes clinical trials, receives regulatory approval and is successfully commercialized. Although we may seek to obtain revenue from collaboration or licensing agreements with third parties, we currently have no such agreements that could provide us with material, ongoing future revenue and we may never enter into any such agreements.

We will require additional financing and may be unable to raise sufficient capital, which could have a material impact on our research and development programs or commercialization of our drug candidates.

We have historically devoted most of our financial resources to research and development, including pre-clinical and clinical development activities. To date, we have financed a significant amount of our operations through equity financings. The amount of our future net losses will depend, in part, on the rate of our future expenditures and our ability to obtain funding through equity or debt financings or strategic collaborations. The amount of such future net losses, as well as the possibility of future profitability, will also depend on our success in developing and commercializing products that generate significant revenue. Our failure to become and remain profitable would depress the value of our ADSs and could impair our ability to raise capital, expand our business, maintain our research and development efforts, diversify our product offerings or even continue our operations.

We anticipate that our expenses will increase substantially for the foreseeable future if, and as, we:

•        continue our research and preclinical and clinical development of our drug candidates;

•        expand the scope of our current proposed clinical studies for our drug candidates;

•        initiate additional preclinical, clinical or other studies for our drug candidates;

•        change or add additional manufacturers or suppliers;

•        seek regulatory and marketing approvals for our drug candidates that successfully complete clinical studies;

•        seek to identify and validate additional drug candidates;

•        acquire or in-license other drug candidates and technologies;

•        maintain, protect and expand our intellectual property portfolio;

•        attract and retain skilled personnel;

•        create additional infrastructure to support our operations as a publicly quoted company and our product development and planned future commercialization efforts;

•        add an internal sales force; and

•        experience any delays or encounter issues with any of the above.

Until our drug candidates become commercially available, we will need to obtain additional funding in connection with the further development of our drug candidates. Our ability to obtain additional financing will be subject to a number of factors, including market conditions, our operating performance and investor sentiment. As such, additional financing may not be available to us when needed, on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts or obtain funds by entering agreements on unattractive terms.

Furthermore, any additional equity fundraising in the capital markets may be dilutive for shareholders and any debt-based funding may bind us to restrictive covenants and curb our operating activities and ability to pay potential future dividends even when profitable. We cannot guarantee that future financing will be available in sufficient amounts or on acceptable terms, if at all. If we are unable to raise additional capital in sufficient amounts or on acceptable terms, we will be prevented from pursuing research and development efforts. This could harm our business, operating results and financial condition and cause the price of our ADSs to fall.

If we are unable to secure sufficient capital to fund our operations, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to third parties to develop and market drug candidates that we would otherwise prefer to develop and market ourselves. For example, additional strategic collaborations could require us to share commercial rights to our drug candidates with third parties in ways that we do not intend currently or on terms that may not be favorable to us. Moreover, we may also have to relinquish valuable rights to our technologies, future revenue streams, research programs or drug candidates or grant licenses on terms that may not be favorable to us.

We may find it difficult to enroll patients in our current and any future clinical trials, and patients could discontinue their participation in our current and any future clinical trials, which could delay or prevent our current and any future clinical trials of our drug candidates and make those trials more expensive to undertake.

Identifying and qualifying patients to participate in current and any future clinical trials of our drug candidates is critical to our success. The timing of our clinical trials depends on the speed at which we can recruit patients to participate in testing our drug candidates. Patients may be unwilling to participate in any future clinical trials because of negative publicity from adverse events in the biotechnology industry. Patients may be unavailable for other reasons, including competitive clinical trials for similar patient populations, and the timeline for recruiting patients, conducting trials and obtaining regulatory approval of potential products may be delayed. If we have difficulty enrolling a sufficient number of patients to conduct any future clinical trials as planned, we may need to delay, limit or discontinue those clinical trials. Clinical trial delays could result in increased costs, slower product development, setbacks in testing the safety and effectiveness of our technology or discontinuation of the clinical trials altogether.

Any failure to implement our business strategy could negatively impact our business, financial condition and results of operations.

The development and commercialization of our drug candidates is subject to many risks, including:

•        additional clinical or pre-clinical trials may be required beyond what we currently expect;

•        regulatory authorities may disagree with our interpretation of data from our preclinical studies and clinical studies or may require that we conduct additional studies;

•        regulatory authorities may disagree with our proposed design of future clinical trials;

•        regulatory authorities may delay approval of our drug candidates, thus preventing milestone payments from our collaboration partners;

•        regulatory authorities may not accept data generated at our clinical study sites;

•        we may be unable to obtain and maintain regulatory approval of our drug candidate in any jurisdiction;

•        the prevalence and severity of any side effects of any drug candidate could delay or prevent commercialization, limit the indications for any approved drug candidate, require the establishment of a risk evaluation and mitigation strategy, or cause an approved drug candidate to be taken off the market;

•        regulatory authorities may identify deficiencies in manufacturing processes;

•        regulatory authorities may change their approval policies or adopt new regulations;

•        the third party manufacturers we expect to depend on to supply or manufacture our drug candidates may not produce adequate supply;

•        we, or our third party manufacturers, may not be able to source or produce current Good Manufacturing Practice (cGMP) materials for the production of our drug candidates;

•        we may not be able to manufacture our drug candidates at a cost or in quantities necessary to make commercially successful products;

•        we may not be able to obtain adequate supply of our drug candidates for our clinical trials;

•        we may experience delays in the commencement of, enrolment of patients in and timing of our clinical trials;

•        we may not be able to demonstrate that our drug candidates are safe and effective as a treatment for its indications to the satisfaction of regulatory authorities, and we may not be able to achieve and maintain compliance with all regulatory requirements applicable to our drug candidates;

•        we may not be able to maintain a continued acceptable safety profile of our products following approval;

•        we may be unable to establish or maintain collaborations, licensing or other arrangements;

•        the market may not accept our drug candidates;

•        we may be unable to establish and maintain an effective sales and marketing infrastructure, either through the creation of a commercial infrastructure or through strategic collaborations, and the effectiveness of our own or any future strategic collaborators’ marketing, sales and distribution strategy and operations will affect our profitability;

•        we may experience competition from existing products or new products that may emerge;

•        we and our licensors may be unable to successfully obtain, maintain, defend and enforce intellectual property rights important to protect our drug candidates; and

•        we may not be able to obtain and maintain coverage and adequate reimbursement from third party payors.

If any of these risks materializes, we could experience significant delays or an inability to successfully develop and commercialize our drug candidates we or our partners may develop, which would have a material adverse effect on our business, financial condition and results of operations.

Positive results from preclinical studies of our drug candidates are not necessarily predictive of the results of our planned clinical trials of our drug candidates.

Positive results in preclinical proof of concept and animal studies of our drug candidates may not result in positive results in clinical trials in humans. Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in clinical trials after achieving positive results in preclinical development or early stage clinical trials, and we cannot be certain that we will not face similar setbacks. These setbacks can be caused by, among other things, preclinical findings made while clinical trials were underway or safety or efficacy observations made in clinical trials, including adverse events. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that believed their drug candidates performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain FDA or other regulatory authority approval. If we fail to produce positive results in our clinical trials of our drug candidates, the development timeline and regulatory approval and commercialization prospects for our drug candidates, and, correspondingly, our business and financial prospects, would be negatively impacted.

Ongoing and future clinical trials of drug candidates may not show sufficient safety and efficacy to obtain requisite regulatory approvals for commercial sale.

Phase I and Phase II clinical trials are not primarily designed to test the efficacy of a drug candidate but rather to test safety and to understand the drug candidate’s side effects at various doses and schedules. Furthermore, success in preclinical and early clinical trials does not ensure that later large-scale trials will be successful nor does it predict final results. Acceptable results in early trials may not be repeated in later trials. Further, Phase III clinical trials may not show sufficient safety or efficacy to obtain regulatory approval for marketing. In addition, clinical results are frequently susceptible to varying interpretations that may delay, limit or prevent regulatory approvals. Negative or inconclusive results or adverse medical events during a clinical trial could require that the clinical trial be redone or terminated. The length of time necessary to complete clinical trials and to submit an application for marketing approval by applicable regulatory authorities may also vary significantly based on the type, complexity and novelty of the drug candidate involved, as well as other factors. If we suffer any significant delays, quality issues, setbacks or negative results in, or termination of, our clinical trials, we may be unable to continue the development of our drug candidates or generate revenue and our business may be severely harmed.

If we do not obtain the necessary regulatory approvals, we will be unable to commercialize our drug candidates.

The clinical development, manufacturing, sales and marketing of our drug candidates are subject to extensive regulation by regulatory authorities in the United States, the United Kingdom, the European Union, Australia and elsewhere. Despite the substantial time and expense invested in preparation and submission of a Biologic License Application or equivalents in other jurisdictions, regulatory approval is never guaranteed. The number, size and design of preclinical studies and clinical trials that will be required will vary depending on the product, the disease or condition for which the product is intended to be used and the regulations and guidance documents applicable to any particular product. Additionally, during the review process and prior to approval, the FDA and/or other regulatory bodies may require additional data, including with respect to whether our products have abuse potential, which may delay approval and any potential controlled substance scheduling processes. The FDA or other regulators can delay, limit or deny approval of a product for many reasons, including, but not limited to, the fact that regulators may not approve our or a third party manufacturer’s processes or facilities or that new laws may be enacted or regulators may change their approval policies or adopt new regulations requiring new or different evidence of safety and efficacy for the intended use of a product.

Successful results in clinical trials and in the subsequent application for marketing approval are not guaranteed. If we are unable to obtain regulatory approvals, we will not be able to generate revenue from our drug candidates. Even if we receive regulatory approval for any of our drug candidates, our profitability will depend on our ability to generate revenues from their sale or the licensing of our technology.

Even if our drug candidates receive regulatory approval, it may still face development and regulatory difficulties that may delay or impair future sales of drug candidates.

Even if we or our licensing partners receive regulatory approval to sell any drug candidates, the relevant regulatory authorities may, nevertheless, impose significant restrictions on the indicated uses, manufacturing, labelling, packaging, adverse event reporting, storage, advertising, promotion and record keeping or impose ongoing requirements for post-approval studies. In addition, regulatory agencies subject a marketed product, its manufacturer and the manufacturer’s facilities to continual review and periodic inspections. Previously unknown problems with the drug candidate, including adverse events of unanticipated severity or frequency, may result in restrictions on the marketing of the product, and could include withdrawal of the product from the market. In addition, new statutory requirements may be enacted or additional regulations may be enacted that could prevent or delay regulatory approval of our drug candidates.

We have limited manufacturing experience with our drug candidates.

We have no manufacturing capabilities and are dependent on third parties for cost effective manufacture and manufacturing process development of the company’s drug candidates. Problems with third party manufacturers or the manufacturing process, or the scaling up of manufacturing activities as such may delay clinical trials and commercialization of our drug candidates.

To the extent we rely significantly on contractors, we will be exposed to risks related to the business and operational conditions of our contractors.

We are a small company, with few internal staff and limited facilities. We are and will be required to rely on a variety of contractors to manufacture and transport our drug candidates, to perform clinical testing and to prepare regulatory dossiers. Adverse events that affect one or more of our contractors could adversely affect us, such as:

•        a contractor is unable to retain key staff that have been working on our drug candidates;

•        a contractor is unable to sustain operations due to financial or other business issues;

•        a contractor loses their permits or licenses that may be required to manufacture our drug candidates; or

•        errors, negligence or misconduct that occur within a contractor may adversely affect our business.

We depend on, and will continue to depend on, collaboration and strategic alliances with third partners. To the extent we are able to enter into collaborative arrangements or strategic alliances, we will be exposed to risks related to those collaborations and alliances.

An important element of our strategy for developing, manufacturing and commercializing our drug candidates is entering into partnerships and strategic alliances with other pharmaceutical companies or other industry participants.

Any partnerships or alliance we have or may have in the future may be terminated for reasons beyond our control or we may not be able to negotiate future alliances on acceptable terms, if at all. These arrangements may result in us receiving less revenue than if we sold our products directly, may place the development, sales and marketing of our products outside of our control, may require us to relinquish important rights or may otherwise be on unfavorable terms. Collaborative arrangements or strategic alliances will also subject us to a number of risks, including the risk that:

•        we may not be able to control the amount and timing of resources that our strategic partner/collaborators may devote to the drug candidates;

•        strategic partner/collaborators may experience financial difficulties;

•        the failure to successfully collaborate with third parties may delay, prevent or otherwise impair the development or commercialization of our drug candidates or revenue expectations;

•        products being developed by partners/collaborators may never reach commercial stage resulting in reduced or even no milestone or royalty payments;

•        business combinations or significant changes in a collaborator’s business strategy may also adversely affect a collaborator’s willingness or ability to complete their obligations under any arrangement;

•        a collaborator could independently move forward with a competing product developed either independently or in collaboration with others, including our competitors; and

•        collaborative arrangements are often terminated or allowed to expire, which would delay the development and may increase the cost of developing drug candidates.

Because we rely on third party manufacturing and supply partners, our supply of research and development, preclinical and clinical development materials may become limited or interrupted or may not be of satisfactory quantity or quality.

We rely on third party supply and manufacturing partners to manufacture and supply the materials for our research and development and preclinical and clinical study supplies. We do not own manufacturing facilities or supply sources for such materials.

There can be no assurance that our supply of research and development, preclinical and clinical development biologics and other materials will not be limited, interrupted or restricted in certain geographic regions, be of satisfactory quality or continue to be available at acceptable prices. Replacement of a third party manufacturer could require significant effort, cost and expertise because there may be a limited number of qualified replacements.

The manufacturing process for a drug candidate is subject to FDA and foreign regulatory authority review. Suppliers and manufacturers must meet applicable manufacturing requirements and undergo rigorous facility and process validation tests required by regulatory authorities in order to comply with regulatory standards. In the event that any of our suppliers or manufacturers fails to comply with such requirements or to perform its obligations to us in relation to quality, timing or otherwise, or if our supply of components or other materials becomes limited or interrupted for other reasons, we may be forced to manufacture the materials ourselves or enter into an agreement with another third party, which would be costly and delay any future clinical trials.

Further, if any third-party provider fails to meet its obligations to manufacture our products, or fails to maintain or achieve satisfactory regulatory compliance, the development of such substances and the commercialization of any therapies, if approved, could be stopped, delayed or made commercially unviable, less profitable or may result in enforcement actions against us.

Our research and development efforts will be jeopardized if we are unable to retain key personnel and cultivate key academic and scientific collaborations.

Changes in our senior management may be disruptive to our business and may adversely affect our operations. For example, when we have changes in senior management positions, we may elect to adopt different business strategies or plans. Any new strategies or plans, if adopted, may not be successful and if any new strategies or plans do not produce the desired results, our business may suffer.

Moreover, competition among biotechnology and pharmaceutical companies for qualified employees is intense and as such we may not be able to attract and retain personnel critical to our success. Our success depends on our continued ability to attract, retain and motivate highly qualified management, clinical and scientific personnel, manufacturing personnel, sales and marketing personnel and on our ability to develop and maintain important relationships with clinicians, scientists and leading academic and health institutions. If we fail to identify, attract, retain and motivate these highly skilled personnel, we may be unable to continue our product development and commercialization activities.

In addition, biotechnology and pharmaceutical industries are subject to rapid and significant technological change. Our drug candidates may be or become uncompetitive. To remain competitive, we must employ and retain suitably qualified staff that are continuously educated to keep pace with changing technology, but may not be in a position to do so.

We may encounter difficulties in managing our growth, which could negatively impact our operations.

As we advance our clinical development programs for drug candidates, seek regulatory approval in the United States and elsewhere and increase the number of ongoing product development programs, we anticipate that we will need to increase our product development, scientific and administrative headcount. We will also need to establish commercial capabilities in order to commercialize any drug candidates that may be approved. Such an evolution may impact our strategic focus and our deployment and allocation of resources.

Our ability to manage our operations and growth effectively depends upon the continual improvement of our procedures, reporting systems and operational, financial and management controls. We may not be able to implement administrative and operational improvements in an efficient or timely manner and may discover deficiencies in existing systems and controls. If we do not meet these challenges, we may be unable to execute our business strategies and may be forced to expend more resources than anticipated addressing these issues.

We may acquire additional technology and complementary businesses in the future. Acquisitions involve many risks, any of which could materially harm our business, including the diversion of management’s attention from core business concerns, failure to effectively exploit acquired technologies, failure to successfully integrate the acquired business or realize expected synergies or the loss of key employees from either our business or the acquired businesses.

In addition, in order to continue to meet our obligations as a public listed company in both Australia and the United States and to support our anticipated long-term growth, we will need to increase our general and administrative capabilities. Our management, personnel and systems may not be adequate to support this future growth.

If we are unable to successfully manage our growth and the increased complexity of our operations, our business, financial position, results of operations and prospects may be harmed.

Future potential sales of our drug candidates may suffer if they are not accepted in the marketplace by physicians, patients and the medical community.

There is a risk that our drug candidates may not gain market acceptance among physicians, patients and the medical community, even if they are approved by the regulatory authorities. The degree of market acceptance of any of our approved drug candidates will depend on a variety of factors, including:

•        timing of market introduction, number and clinical profile of competitive products;

•        our ability to provide acceptable evidence of safety and efficacy and our ability to secure the support of key clinicians and physicians for our drug candidates;

•        cost-effectiveness compared to existing and new treatments;

•        availability of coverage, reimbursement and adequate payment from health maintenance organizations and other third party payers;

•        prevalence and severity of adverse side effects; and

•        other advantages over other treatment methods.

As controlled substances, the products may generate public controversy. Physicians, patients, payers or the medical community may be unwilling to accept, use or recommend our drug candidates which would adversely affect our potential revenues and future profitability. Adverse publicity or public perception regarding cannabis and psilocybin to our current or future investigational therapies using these substances may negatively influence the success of these therapies.

We face competition from entities that may develop drug candidates for our target disease indications, including companies developing novel treatments and technology platforms based on modalities and technology similar to ours.

The development and commercialization of drug candidates is highly competitive. Multinational pharmaceutical companies and specialized biotechnology companies could develop drug candidates and processes competitive with our drug candidates. Competitive therapeutic treatments include those that have already been approved and accepted by the medical community, patients and third party payers, and any new treatments that enter the market.

There may be a significant number of products that are currently under development, and may become commercially available in the future, for the treatment of conditions for which we are developing, and may in the future try to develop, drug candidates.

Multinational pharmaceutical companies and specialized biotechnology companies could have significantly greater financial, technical, manufacturing, marketing, sales and supply resources and experience than we have. If we successfully obtain approval for any drug candidate, we could face competition based on many different factors, including the safety and effectiveness of our drug candidates, the ease with which our drug candidates can be administered and the extent to which patients accept relatively new routes of administration, the timing and scope of regulatory approvals for these drug candidates, the availability and cost of manufacturing, marketing and sales capabilities, price, reimbursement coverage and patent position.

Competing products could present superior treatment alternatives, including by being more effective, safer, less expensive or marketed and sold more effectively than any products we may develop. Competitive products may make any products we develop obsolete or non-competitive before we recover the expense of developing and commercializing our drug candidates. Such competitors could also recruit our employees, which could negatively impact our level of expertise and our ability to execute our business plan.

If healthcare insurers and other organizations do not pay for our drug candidates or impose limits on reimbursement, our future business may suffer.

Our drug candidates may be rejected by the market due to many factors, including cost. The continuing efforts of governments, insurance companies and other payers of healthcare costs to contain or reduce healthcare costs may affect our future revenues and profitability. In Australia and certain foreign markets, the pricing of pharmaceutical products is subject to government control. We expect initiatives for similar government control to continue in the United States and elsewhere. The adoption of any such legislative or regulatory proposals could harm our business and prospects.

Successful commercialization of our drug candidates will depend in part on the extent to which reimbursement for the cost of our products and related treatment will be available from government health administration authorities, private health insurers and other organizations. Our drug candidates may not be considered cost-effective and reimbursement may not be available to consumers or may not be sufficient to allow our products to be marketed on a competitive basis. Third-party payers are increasingly challenging the price of medical products and treatment.

If third party coverage is not available for our drug candidates the market acceptance of these drug candidates will be reduced. Cost-control initiatives could decrease the price we might establish for drug candidates, which could result in product revenues lower than anticipated. If the price for our drug candidates decreases or if governmental and other third-party payers do not provide adequate coverage and reimbursement levels our potential revenue and prospects for profitability will suffer.

We may be exposed to product liability claims which could harm our business.

The testing, marketing and sale of therapeutic products entails an inherent risk of product liability. We rely on a number of third-party researchers and contractors to produce, collect, and analyze data regarding the safety and efficacy of our drug candidates. We also have quality control and quality assurance in place to mitigate these risks, as well as professional liability and clinical trial insurance to cover financial damages in the event that human testing is done incorrectly or the data is analyzed incorrectly.

Notwithstanding our control procedures, we may face product liability exposure related to the testing of our drug candidates in human clinical trials. If any of our drug candidates are approved for sale, we may face exposure to claims by an even greater number of persons than were involved in the clinical trials once marketing, distribution and sales of our drug candidates begin. Regardless of merit or eventual outcome, liability claims may result in:

•        decreased demand for our drug candidates;

•        injury to our reputation;

•        withdrawal of clinical trial participants;

•        costs of related litigation;

•        substantial monetary awards to patients and others;

•        loss of revenues; and

•        the inability to commercialize drug candidates.

With respect to product liability claims, we could face additional liability beyond insurance limits if testing mistakes were to endanger any human subjects. In addition, if a claim is made against us in conjunction with these research testing activities, the market price of our ADSs may be negatively affected.

The outbreak of the novel strain of coronavirus, SARS-CoV-2, which causes COVID-19, could adversely impact our business, including our non-clinical studies and clinical trials.

Public health crises such as pandemics or similar outbreaks might adversely impact our business. In December 2019, a novel strain of coronavirus, SARS-CoV-2, which causes coronavirus disease 2019 (COVID-19), surfaced in Wuhan, China. Since then, COVID-19 has spread to most countries in the world.

As a result of the COVID-19 outbreak, or similar pandemics, we have and may in the future experience disruptions that could severely impact our business, preclinical studies and clinical trials, including:

•        delays or difficulties in enrolling patients in our clinical trials;

•        delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;

•        delays or disruptions in non-clinical experiments and investigational new drug application-enabling good laboratory practice standard toxicology studies due to unforeseen circumstances at contract research organizations and vendors along their supply chain;

•        increased rates of patients withdrawing from our clinical trials following enrollment as a result of contracting COVID-19, being forced to quarantine, or not wanting to attend hospital visits;

•        diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials;

•        interruption of key clinical trial activities, such as clinical trial site data monitoring, due to limitations on travel imposed or recommended by national, state or local governments, employers and others or interruption of clinical trial subject visits and study procedures (particularly any procedures that may be deemed non-essential), which may impact the integrity of subject data and clinical study endpoints;

•        interruption or delays in the operations of the U.S. Food and Drug Administration, the European Medicines Agency, the Australian Therapeutic Goods Administration or other foreign regulatory agencies, which may impact approval timelines;

•        interruption of, or delays in receiving, supplies of our drug candidates from our contract manufacturing organizations due to staffing shortages, production slowdowns or stoppages and disruptions in our supply chain or distribution vendors’ ability to ship drug candidates; and

•        limitations on employee resources that would otherwise be focused on the conduct of our non-clinical studies and clinical trials, including because of sickness of employees or their families, the desire of employees to avoid contact with large groups of people, an increased reliance on working from home or mass transit disruptions.

Product shipment delays could have a material adverse effect on our business, results of operations and financial condition.

The shipment, import and export of our drug candidates and the API used to manufacture them will require import and export licenses. In the United States, the FDA, U.S. Customs and Border Protection, and the DEA; in Canada, the Canada Border Services Agency, Health Canada; in Europe, the EMA and the European Commission; in Australia and New Zealand, the Australian Customs and Board Protection Service, the TGA, the New Zealand Medicines and Medical Device Safety Authority and the New Zealand Customs Service; and in other countries, similar regulatory authorities, regulate the import and export of pharmaceutical products that contain controlled substances. Specifically, the import and export processes require the issuance of import and export licenses by the relevant controlled substance authority in both the importing and exporting country.

We may not be granted, or if granted, maintain, such licenses from the authorities in certain countries. Even if we obtain the relevant licenses, shipments of API and our drug candidates may be held up or lost in transit, which could cause significant delays and may lead to product batches being stored outside required temperature ranges. Inappropriate storage may damage the product shipment resulting in delays in clinical trials or, upon commercialization, a partial or total loss of revenue from one or more shipments of API or our drug candidates. A delay in a clinical trial or, upon commercialization, a partial or total loss of revenue from one or more shipments of API or our drug candidates could have a material adverse effect on our business, results of operations and financial condition.

Our drug candidates will be subject to controlled substance laws and regulations. Failure to receive necessary approvals may delay the launch of our drug candidates and failure to comply with these laws and regulations may adversely affect the results of our business operations.

Our drug candidates contain controlled substances as defined in the Controlled Substance Act (“CSA”). Controlled substances that are pharmaceutical products are subject to a high degree of regulation under the CSA, which establishes, among other things, certain registration, manufacturing quotas, security, recordkeeping, reporting, import, export and other requirements administered by the DEA. The DEA classifies controlled substances into five schedules: Schedule I, II, III, IV or V substances. Schedule I substances by definition have a high potential for abuse, have not currently “accepted medical use” in the United States, lack accepted safety for use under medical supervision, and may not be prescribed, marketed or sold in the United States. Pharmaceutical products approved for use in the United States may be listed as Schedule II, III, IV or V, with Schedule II substances considered to present the highest potential for abuse or dependence and Schedule V substances the lowest relative risk of abuse among such substances. Schedule I and II drugs are subject to the strictest controls under the CSA, including manufacturing and procurement quotas, security requirements and criteria for importation. In addition, dispensing of Schedule II drugs is further restricted. For example, they may not be refilled without a new prescription.

As a synthetic cannabinoids pharmaceutical product with psychedelic agents, our drug candidates are likely to be scheduled as Schedule II or III controlled substance. We will need to identify wholesale distributors with the appropriate DEA registrations and authority to distribute the products to pharmacies and other healthcare providers, and these distributors would need to obtain Schedule II or III distribution registrations. The failure to obtain, or delay in obtaining, or the loss of any of those registrations could result in increased costs to us. If any of our drug candidates is a Schedule II drug, pharmacies would have to maintain enhanced security with alarms and monitoring systems, and they must adhere to additional recordkeeping and inventory requirements. This may discourage some pharmacies from carrying the product. Furthermore, state and federal enforcement actions, regulatory requirements, and legislation intended to reduce prescription drug abuse, such as the requirement that physicians consult a state prescription drug monitoring program, may make physicians less willing to prescribe, and pharmacies to dispense, Schedule II products.

We intend to manufacture the commercial supply of our drug candidates outside of the United States. If any of our products are approved by the FDA and classified as a Schedule II or III substance, an importer can import for commercial purposes if it obtains from the DEA an importer registration and files an application with the DEA for an import permit for each import. The failure to identify an importer or obtain the necessary import authority could affect the availability of our drug candidates and have a material adverse effect on our business, results of operations and financial condition. In addition, an application for a Schedule II importer registration must be published in the Federal Register, and there is a waiting period for third party comments to be submitted. The failure to maintain the necessary registrations or comply with applicable laws could delay the commercialization of our drug candidates and could delay the completion of the clinical studies. Furthermore, failure to maintain compliance with the CSA, particularly non-compliance resulting in loss or diversion, could result in regulatory action that could have a material adverse effect on our business, financial condition and results of operations. The DEA may seek civil penalties, refuse to renew necessary registrations, or initiate proceedings to restrict, suspend or revoke those registrations. In certain circumstances, violations could lead to criminal proceedings. In addition, if the FDA, DEA, or any foreign regulatory authority determines that our drug candidates may have potential for abuse, it may require us to generate more clinical or other data than we currently anticipate to establish whether or to what extent the substance has an abuse potential, which could increase the cost and/or delay the launch of which could increase the cost and/or delay the launch of our drug candidates.

Individual states have also established controlled substance laws and regulations. Though state-controlled substance laws often mirror federal law, because the states are separate jurisdictions, they may separately schedule our drug candidates as well. While some states automatically schedule a drug based on federal action, other states schedule drugs through rulemaking or a legislative action. State scheduling may delay commercial sale of any product for which we obtain federal regulatory approval and adverse scheduling could have a material adverse effect on the commercial attractiveness of such product. We or our partners must also obtain separate state registrations, permits or licenses in order to be able to obtain, handle, and distribute controlled substances for clinical trials or commercial sale, and failure to meet applicable regulatory requirements could lead to enforcement and sanctions by the states in addition to those from the DEA or otherwise arising under federal law.

We intend to contract manufacturers in Australia to produce the drug product for our clinical trials and the API for our drug candidates. In addition, we may decide to develop, manufacture or commercialize our drug candidates in additional countries. As a result, we will also be subject to controlled substance laws and regulations from the TGA in Australia and from other regulatory agencies in other countries where we develop, manufacture or commercialize our drug candidates in the future. We plan to submit NDAs for our drug candidates to the FDA upon completion of all requisite clinical trials and may require additional DEA scheduling decisions at such time as well.

Changes in U.S. healthcare law and implementing regulations, as well as changes in healthcare policy, may impact our business in ways that we cannot currently predict and may harm our business and results of operations.

There have been, and likely will continue to be, several executive, legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of drug candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any drug candidates for which we obtain marketing approval. Among policy makers and payors in the United States there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access and the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, collectively referred to as the Affordable Care Act, substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the U.S. pharmaceutical industry. The Affordable Care Act, among other things: (1) introduced a new average manufacturer price definition for drugs and biologics that are inhaled, infused, instilled, implanted or injected and not generally dispensed through retail community pharmacies; (2) increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and expanded rebate liability from fee-for-service Medicaid utilization to include the utilization of Medicaid managed care organizations as well; (3) established a branded prescription drug fee that pharmaceutical manufacturers of branded prescription drugs must pay to the federal government; (4) expanded the list of covered entities eligible to participate in the 340B drug pricing program by adding new entities eligible for the program; (5) established a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% (increased to 70% pursuant to the Bipartisan Budget Act of 2018, or BBA, effective as of January 2019) point-of-sale discounts off negotiated prices of applicable branded drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D; (6) extended manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed care organizations; (7) expanded eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals, including individuals with income at or below 133% of the federal poverty level, thereby potentially increasing manufacturers’ Medicaid rebate liability; (8) created a licensure framework for follow-on biologic products; and (9) established a Center for Medicare and Medicaid Innovation at the CMS to test innovative payment and service delivery models to lower Medicare and Medicaid spending.

There remain judicial and Congressional challenges to certain aspects of the Affordable Care Act, as well as efforts by the Trump administration to repeal or replace certain aspects of the Affordable Care Act. For example, the Tax Cuts and Jobs Act of 2017, or the TCJA, was enacted, which included a provision that repealed, effective January 1, 2019, the tax-based shared responsibility payment imposed by the Affordable Care Act on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate.” On December 14, 2018, a U.S. District Court Judge in the Northern District of Texas ruled that the individual mandate is a critical and inseverable feature of the Affordable Care Act, and therefore, because it was repealed as part of the TCJA, the remaining provisions of the Affordable Care Act are invalid as well. On December 18, 2019, the U.S. Court of Appeals for the 5th Circuit ruled that the individual mandate was unconstitutional but remanded the case back to the District Court to determine whether the remaining provisions of the Affordable Care Act are invalid as well. On March 2, 2020, the U.S. Supreme Court granted the petitions for writs of certiorari to review the case, although it is unclear when a decision will be made or how the Supreme Court will rule. In addition, there may be other efforts to challenge, repeal or replace the Affordable Care Act. We are continuing to monitor any changes to the Affordable Care Act that, in turn, may potentially impact our business in the future.

Other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. These changes include aggregate reductions to Medicare payments to providers of 2% per fiscal year pursuant to the Budget Control Act of 2011 and subsequent laws, which began in 2013 and will remain in effect through 2030, unless additional Congressional action is taken. These Medicare sequester reductions will be suspended from May 1, 2020 through December 31, 2020 due to the COVID-19 pandemic. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several types of providers, including hospitals, imaging centers and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. New laws may result in additional reductions in Medicare and other healthcare funding, which may materially negatively affect customer demand and affordability for our drug candidates and, accordingly, the results of our financial operations. Also, there has been heightened governmental scrutiny recently over the manner in which pharmaceutical companies set prices for their marketed products, which have resulted in several Congressional inquiries and proposed federal legislation, as well as state efforts, designed to, among other things, bring more transparency to product pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. At the state level, individual states in the United States are increasingly active in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or

patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third-party payors or other restrictions on coverage or access could harm our business, results of operations, financial condition and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our drug candidates that we successfully commercialize or put pressure on our product pricing.

In addition, proposed federal and state legislation may increase competition as it relates to cannabis derived products. Under the Cannabis Administration and Opportunity Act, the U.S. Senate proposed legalizing the use of hemp-derived CBD in dietary supplements by amending the FDCA. The Hemp Access and Consumer Safety Act of 2021 (SB 1698) also permits hemp-derived CBD to be used in dietary supplements. States are considering the reimbursement of medical marijuana. For example, New Jersey lawmakers introduced legislation, which is still pending, that requires reimbursement for medical marijuana under certain circumstances, while New York lawmakers introduced pending legislation that classifies medical marijuana as a prescription drug that may be covered for workers’ compensation purposes. As the availability and reimbursement of cannabis-derived products potentially expand, the pharmaceutical industry may directly compete with state-regulated cannabis businesses for market share.

We expect that these and other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and lower reimbursement, and put additional downward pressure on the price that we receive for any approved product. It is possible that additional governmental action is taken in response to the COVID-19 pandemic. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action in the United States. If we or any third parties we may engage are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or such third parties are not able to maintain regulatory compliance, our drug candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability

Risks Related to Intellectual Property

Our success depends on our ability to protect our intellectual property and our proprietary technology.

Our success is to a certain degree also dependent on our ability to obtain and maintain patent protection or where applicable, to receive/maintain orphan drug designation/status and resulting marketing exclusivity for our drug candidates.

We may be materially adversely affected by our failure or inability to protect our intellectual property rights. Without the granting of these rights, the ability to pursue damages for infringement would be limited. Similarly, any know-how that is proprietary or particular to our technologies may be subject to risk of disclosure by employees or consultants despite having confidentiality agreements in place.

Any future success will depend in part on whether we can obtain and maintain patents to protect our own products and technologies; obtain licenses to the patented technologies of third parties; and operate without infringing on the proprietary rights of third parties. Biotechnology patent matters can involve complex legal and scientific questions, and it is impossible to predict the outcome of biotechnology and pharmaceutical patent claims. Any of our future patent applications may not be approved, or we may not develop additional products or processes that are patentable. Some countries in which we may sell our drug candidate or license our intellectual property may fail to protect our intellectual property rights to the same extent as the protection that may be afforded in the United States or Australia. Some legal principles remain unresolved and there has not been a consistent policy regarding the breadth or interpretation of claims allowed in patents in the United States, the United Kingdom, the European Union, Australia or elsewhere. In addition, the specific content of patents and patent applications that are necessary to support and interpret patent claims is highly uncertain due to the complex nature of the relevant legal, scientific and factual issues. Changes in either patent laws or in interpretations of patent laws in the United States, the United Kingdom, the European Union or elsewhere may diminish the value of our intellectual property or narrow the scope of our patent protection. Even if we are able to obtain patents, they may not issue in a form that

will provide us with any meaningful protection, prevent competitors from competing with us or otherwise provide us with any competitive advantage. Our competitors may be able to circumvent our patents by developing similar or alternative technologies or products in a non-infringing manner. We may also fail to take the required actions or pay the necessary fees to maintain our patents.

Moreover, any of our pending applications may be subject to a third party pre-issuance submission of prior art to the U.S. Patent and Trademark Office, or USPTO, the European Patent Office, or EPO, the Intellectual Property Office, or IPO, in the United Kingdom, the Australian Patent and Trademark Office and/or any patents issuing thereon may become involved in opposition, derivation, reexamination, inter partes review, post grant review, interference proceedings or other patent office proceedings or litigation, in the United States or elsewhere, challenging our patent rights. An adverse determination in any such submission, proceeding or litigation could reduce the scope of, or invalidate, our patent rights, and allow third parties to commercialize our technology or products and compete directly with us, without payment to us. In addition, if the breadth or strength of protection provided by our patents and patent applications is threatened, it could dissuade companies from collaborating with us to exploit our intellectual property or develop or commercialize current or future drug candidates.

The issuance of a patent is not conclusive as to the inventorship, scope, validity or enforceability, and our patents may be challenged in the courts or patent offices in the United States, the European Union, Australia and elsewhere. Such challenges may result in loss of ownership or in patent claims being narrowed, invalidated or held unenforceable, in whole or in part, which could limit the duration of the patent protection of our technology and products. As a result, our patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

In addition, other companies may attempt to circumvent any regulatory data protection or market exclusivity that we obtain under applicable legislation, which may require us to allocate significant resources to preventing such circumvention. Such developments could enable other companies to circumvent our intellectual property rights and use our clinical trial data to obtain marketing authorizations in the European Union, Australia and in other jurisdictions. Such developments may also require us to allocate significant resources to prevent other companies from circumventing or violating our intellectual property rights.

Intellectual property rights of third parties could adversely affect our ability to commercialize our drug candidates, such that we could be required to litigate with or obtain licenses from third parties in order to develop or market our drug candidates.

Our commercial success may depend upon our future ability and the ability of our potential collaborators to develop, manufacture, market and sell our drug candidates without infringing valid intellectual property rights of third parties.

If a third-party intellectual property right exists it may require the pursuit of litigation or administrative proceedings to nullify or invalidate the third party intellectual property right concerned, or entry into a license agreement with the intellectual property right holder, which may not be available on commercially reasonable terms, if at all.

Third-party intellectual property right holders, including our competitors, may bring infringement claims against us. We may not be able to successfully settle or otherwise resolve such infringement claims. If we are unable to successfully settle future claims or otherwise resolve such claims on terms acceptable to us, we may be required to engage in or continue costly, unpredictable and time-consuming litigation and may be prevented from, or experience substantial delays in, marketing our drug candidate.

If we fail to settle or otherwise resolve any such dispute, in addition to being forced to pay damages, we or our potential collaborators may be prohibited from commercializing any drug candidates we may develop that are held to be infringing, for the duration of the patent term. We might, if possible, also be forced to redesign our formulations so that we no longer infringe such third-party intellectual property rights. Any of these events, even if we were ultimately to prevail, could require us to divert substantial financial and management resources that we would otherwise be able to devote to our business.

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed.

Because we collaborate with various organizations and academic institutions on the advancement of our technology and drug candidates, we may, at times, share trade secrets with them. We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if applicable, material transfer agreements, collaborative research agreements, consulting agreements or other similar agreements with our collaborators, advisors, employees and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of the third parties to use or disclose our confidential information, such as trade secrets. Despite these contractual provisions, the need to share trade secrets and other confidential information increases the risk that such trade secrets become known by potential competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, discovery by a third party of our trade secrets or other unauthorized use or disclosure would impair our intellectual property rights and protections in our drug candidates.

In addition, these agreements typically restrict the ability of our collaborators, advisors, employees and consultants to publish data potentially relating to our trade secrets. Our academic collaborators typically have rights to publish data, provided that we are notified in advance and may delay publication for a specified time in order to secure our intellectual property rights arising from the collaboration. In other cases, publication rights are controlled exclusively by us. In other cases, we may share these rights with other parties. Despite our efforts to protect our trade secrets, our competitors may discover our trade secrets, either through breach of these agreements, independent development or publication of information including our trade secrets in cases where we do not have proprietary or otherwise protected rights at the time of publication.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Periodic maintenance fees, renewal fees, annuity fees and various other governmental fees on patents and applications are required to be paid to the United State Patent and Trademark Office and other governmental patent agencies outside of the United States in several stages over the lifetime of the patents and applications. The USPTO and various corresponding governmental patent agencies outside of the United States require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process and after a patent has issued. There are situations in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction.

We may become involved in lawsuits to protect and defend our patents or other intellectual property, which could be expensive, time consuming and unsuccessful.

Competitors may infringe our patents or other intellectual property and we may inadvertently infringe the patent or intellectual property of others. To counter infringement or unauthorized use, we may be required to file claims, and any related litigation and/or prosecution of such claims can be expensive and time consuming. Any claims we assert against perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their intellectual property. In addition, in a patent infringement proceeding, a court may decide that a patent of ours is invalid in whole or in part, unenforceable, or construe the patent’s claims narrowly allowing the other party to commercialize competing products on the grounds that our patents do not cover such products.

Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses and could distract our technical and management personnel from their normal responsibilities. Such litigation or proceedings could substantially increase our operating losses and reduce our resources available for development activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their substantially greater financial resources. The effects of patent litigation or other proceedings could therefore have a material adverse effect on our ability to compete in the marketplace.

Confidentiality and invention assignment agreements with our employees, advisors and consultants may not adequately prevent disclosure of trade secrets and protect other proprietary information.

We consider proprietary trade secrets and/or confidential know-how and unpatented know-how to be important to our business. We may rely on trade secrets and/or confidential know-how to protect our technology, especially where patent protection is believed by us to be of limited value. However, trade secrets and/or confidential know-how can be difficult to maintain as confidential.

To protect this type of information against disclosure or appropriation by competitors, our policy is to require our employees, advisors and consultants to enter into confidentiality and invention assignment agreements with us. However, current or former employees, advisors and consultants may unintentionally or willfully disclose our confidential information to competitors, and confidentiality and invention assignment agreements may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. Enforcing a claim that a third party obtained illegally and is using trade secrets and/or confidential know-how is expensive, time consuming and unpredictable. The enforceability of confidentiality and invention assignment agreements may vary from jurisdiction to jurisdiction.

Failure to obtain or maintain trade secrets and/or confidential know-how trade protection could adversely affect our competitive position. Moreover, our competitors may independently develop substantially equivalent proprietary information and may even apply for patent protection in respect of the same. If successful in obtaining such patent protection, our competitors could limit our use of our trade secrets and/or confidential know-how.

Intellectual property rights do not address all potential threats to our competitive advantage.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business, or permit us to maintain our competitive advantage. The following examples are illustrative:

•        Others may be able to make products that are similar to ours but that are not covered by our intellectual property rights.

•        Others may independently develop similar or alternative technologies or otherwise circumvent any of our technologies without infringing our intellectual property rights.

•        We or any of our collaboration partners might not have been the first to conceive and reduce to practice the inventions covered by the patents or patent applications that we own, license or will own or license.

•        We or any of our collaboration partners might not have been the first to file patent applications covering certain of the patents or patent applications that we or they own or have obtained a license, or will own or will have obtained a license.

•        It is possible that any pending patent applications that we have filed, or will file, will not lead to issued patents.

•        Issued patents that we own may not provide us with any competitive advantage, or may be held invalid or unenforceable, as a result of legal challenges by our competitors.

•        Our competitors might conduct research and development activities in countries where we do not have patent rights, or in countries where research and development safe harbor laws exist, and then use the information learned from such activities to develop competitive products for sale in our major commercial markets.

•        Ownership of our patents or patent applications may be challenged by third parties.

•        The patents of third parties or pending or future applications of third parties, if issued, may have an adverse effect on our business.

We may face difficulties with protecting our intellectual property in certain jurisdictions, which may diminish the value of our intellectual property rights in those jurisdictions.

The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws in the United States and the European Union, and many companies have encountered significant difficulties in protecting and defending such rights in such jurisdictions. If we or our collaboration partners encounter difficulties in protecting, or are otherwise precluded from effectively protecting, the intellectual property rights important for our business in such jurisdictions, the value of these rights may be diminished and we may face additional competition from others in those jurisdictions.

Some countries in Europe and China have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we are, or any of our licensors is, forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position or commercial advantage may be impaired and our business and results of operations may be adversely affected.

Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our drug candidates and any future drug candidates.

As is the case with other biotechnology and pharmaceutical companies, our success is heavily dependent on intellectual property rights, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involves technological and legal complexity, and obtaining and enforcing biopharmaceutical patents is costly, time-consuming and inherently uncertain. The U.S. Supreme Court in recent years has issued rulings either narrowing the scope of patent protection available in certain circumstances or weakening the rights of patent owners in certain situations or ruling that certain subject matter is not eligible for patent protection. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has created uncertainty with respect to the value of patents, once obtained. Depending on decisions by Congress, the federal courts, the USPTO and equivalent bodies in non-U.S. jurisdictions, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce existing patents and patents we may obtain in the future.

Patent reform laws, such as the Leahy-Smith America Invents Act, or the Leahy-Smith Act, as well as changes in how patent laws are interpreted, could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. The Leahy-Smith Act made a number of significant changes to U.S. patent law. These include provisions that affect the filing and prosecution strategies associated with patent applications, including a change from a “first-to-invent” to a “first-inventor-to-file” patent system, and a change allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTO-administered post-grant proceedings, including post-grant review, inter partes review and derivation proceedings. The USPTO has developed regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act and, in particular, the “first-inventor-to-file” provisions, became effective in 2013. The Leahy-Smith Act and its implementation may increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have harm our business, financial condition and results of operations.

Price controls may be imposed in non-U.S. markets, which may negatively affect our future profitability.

In some countries, particularly EU member states, Japan, Australia and Canada, the pricing of prescription drugs is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time after receipt of marketing approval for a product. In addition, there can be considerable pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost containment measures. Political, economic and regulatory developments may further complicate pricing negotiations, and pricing negotiations may continue after reimbursement has been obtained. Reference pricing used by various EU member states and parallel distribution, or arbitrage between low-priced and

high-priced member states, can further reduce prices. In some countries, we or our collaborators may be required to conduct a clinical trial or other studies that compare the cost-effectiveness of our drug candidates to other available therapies in order to obtain or maintain reimbursement or pricing approval. Publication of discounts by third-party payors or authorities may lead to further pressure on the prices or reimbursement levels within the country of publication and other countries. If reimbursement of our drug candidates is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business, revenues or profitability could be harmed.

Risks Relating to Ownership of the ADSs and this Offering

The trading price of the ADSs may be volatile, and purchasers of the ADSs could incur substantial losses.

The market price of our ordinary shares historically has been, and we expect our ordinary shares and ADSs will continue to be, subject to significant fluctuations over short periods of time. These fluctuations may be due to factors specific to us, to changes in analysts’ recommendations and earnings estimates, to arbitrage between our Australian-listed ordinary shares and our Nasdaq-listed ADSs, to changes in exchange rates, or to factors affecting the biopharmaceutical industry or the securities markets in general. Market fluctuations, as well as general political and economic conditions, such as a recession, interest rate or currency fluctuations, could adversely affect the market price of our securities.

We may experience a material decline in the market price of our shares, regardless of our operating performance. Therefore, a holder of our ADSs may not be able to sell those ADSs at or above the price paid by such holder for such ADSs. Price declines in our ADSs could result from a variety of factors, including many outside our control. These factors include:

•        the results of pre-clinical testing and clinical trials by us and our competitors;

•        unforeseen safety issues or adverse side effects resulting from the clinical trials or the commercial use of our drug candidate;

•        regulatory actions in respect of any of our drug candidates or the products of any of our competitors;

•        announcements of the introduction of new products by us or our competitors;

•        market conditions, including market conditions in the pharmaceutical and biotechnology sectors;

•        increases in our costs or decreases in our revenues due to unfavorable movements in foreign currency exchange rates;

•        developments or litigation concerning patents, licenses and other intellectual property rights;

•        litigation or public concern about the safety of our drug candidates;

•        changes in recommendations or earnings estimates by securities analysts;

•        actual and anticipated fluctuations in our quarterly operating results;

•        deviations in our operating results from the estimates of securities analysts;

•        rumors relating to us or our competitors;

•        additions or departures of key personnel;

•        changes in third party reimbursement policies; and

•        developments concerning current or future strategic alliances or acquisitions.

In addition, volatility and low market price of our ADSs may adversely impact investors’ interest in our securities. A decline in investors’ interest may prompt further volatility and decrease in market price.

There has been no prior market for the ADSs and an active and liquid market for our securities may fail to develop, which could harm the market price of the ADSs.

While our ordinary shares have been listed on the Australian Securities Exchange, or ASX, prior to this offering, there has been no public market on a U.S. national securities exchange for our ordinary shares or ADSs. Although we have applied for the listing of the ADSs on Nasdaq, an active trading market for the ADSs may never develop or be sustained following this offering. The initial offering price of the ADSs will be determined through negotiations between us and the underwriter and will be based, in part, on prevailing market prices of our ordinary shares on the ASX, after taking into account market conditions and other factors. This offering price may not be indicative of the market price of the ADSs after this offering. In the absence of an active trading market for the ADSs, investors may not be able to sell their ADSs at or above the offering price or at the time that they would like to sell.

If we are or become a passive foreign investment company (“PFIC” ), then that would subject our U.S. investors to adverse tax rules.

Holders of our ADSs who are U.S. taxpayers will be subject to particular income tax rules if we are a passive foreign investment company, or PFIC. These rules could result in a reduction in the after-tax return to a “U.S. Holder” of our ADSs and reduce the value of our ADSs. For U.S. federal income tax purposes, we will be classified as a PFIC for any taxable year in which (i) 75% or more of our gross income is passive income, or (ii) at least 50% of the average value of all of our assets for the taxable year produce or are held for the production of passive income. For this purpose, cash is considered to be an asset that produces passive income.

If we are classified as a PFIC in any year that a U.S. Holder owns ADSs, the U.S. Holder will generally continue to be treated as holding ADSs of a PFIC in all subsequent years, notwithstanding that we are not classified as a PFIC in a subsequent year. Dividends received by the U.S. Holder and gains realized from the sale of our ADSs would be taxed as ordinary income and subject to an interest charge. We urge U.S. investors to consult their own tax advisors about the application of the PFIC rules and certain elections that may help to minimize adverse U.S. federal income tax consequences in their particular circumstances.

The requirements of being a public company may strain our resources and divert management’s attention and if we are unable to maintain effective internal control over financial reporting in the future, the accuracy and timeliness of our financial reporting may be adversely affected.

As a U.S. publicly-traded company, we will be subject to the reporting requirements of the U.S. Securities Exchange Act of 1934, as amended (the Exchange Act), the Sarbanes-Oxley Act, the Dodd-Frank Act, the listing requirements of the Nasdaq Capital Market and other applicable securities rules and regulations. Compliance with these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and increase demand on our systems and resources. The Exchange Act requires, among other things, that we file certain reports with respect to our business and results of operations. The Sarbanes-Oxley Act requires that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight are required. As a result, management’s attention may be diverted from other business concerns, which could adversely affect our business and results of operations.

The Sarbanes-Oxley Act requires that we assess the effectiveness of our internal control over financial reporting annually and disclosure controls and procedures quarterly. If we identify material weaknesses in future periods or we are not able to comply with the requirements of Section 404 in a timely manner, our reported financial results could be restated, we could be subject to investigations or sanctions by regulatory authorities, which would require additional financial and management resources, and the market price of our ordinary shares could decline.

You will experience immediate and substantial dilution in the net tangible book value of the ADSs you purchase in this offering.

The initial public offering price of the ADSs is substantially higher than the net tangible book value per ADS or per ordinary share immediately after this offering. If you purchase ADSs in this offering, you will suffer immediate dilution of US$            per ADS (or US$            per ordinary share), or US$            per ADS

(or US$            per ordinary share) if the underwriter exercises its option to purchase additional shares in full, representing the difference between our as adjusted net tangible book value per ADS or per ordinary share after giving effect to the sale of ADSs in this offering and the initial public offering price of US$            per ADS. See “Dilution.”

Our issuance of additional ordinary shares in connection with financings, acquisitions, investments, or otherwise will dilute all other ADS holders.

We expect to issue additional ordinary shares in the future that will result in dilution to all other ADS holders. We may also raise capital through equity financings in the future. As part of our business strategy, we may acquire or make investments in complementary companies, products, or technologies and issue equity securities to pay for any such acquisition or investment. While we will be subject to the constraints of the ASX Listing Rules regarding the percentage of our capital that we are able to issue within a 12-month period (subject to applicable exceptions), any such issuances of additional ordinary shares may cause ADS holders to experience significant dilution of their ownership interests and the per ADS value of our ADSs to decline.

As long as we remain subject to the rules of the ASX and Nasdaq, we will be unable to access equity capital without shareholder approval if such equity capital sales would result in an equity issuance above regulatory thresholds and, consequently, we could be unable to obtain financing sufficient to sustain our business if we are unsuccessful in soliciting requisite shareholder approvals.

Our ability to access equity capital is currently limited by ASX Listing Rule 7.1, which provides that a company must not, subject to specified exceptions (including approval by shareholders), issue or agree to issue during any consecutive 12-month period any equity securities, or other securities with rights to conversion to equity, if the number of those securities in aggregate would exceed 15% of the number of ordinary securities on issue at the commencement of that 12-month period.

Our equity issuances will be limited by ASX Listing Rule 7.1 as long as we continue to be listed on the ASX and this constraint may prevent us from raising the full amount of equity capital needed for operations without prior shareholder approval.

We have broad discretion in the use of the net proceeds from this offering and may not use them effectively.

We will have broad discretion in the application of the net proceeds that we receive from this offering as well as of our existing cash, and we may spend or invest these funds in a way with which our shareholders or holders of the ADSs disagree. Our failure to apply these funds effectively could harm our business and financial condition. Pending their use, we may invest the net proceeds from the offering in a manner that does not produce income or that loses value. These investments may not yield a favorable return to our investors.

Future sales of ordinary shares or ADSs by existing holders could depress the market price of the ordinary shares or ADSs.

Based on 1,065,859,479 ordinary shares outstanding as of June 30, 2021, upon the closing of this offering, we will have outstanding a total of            ordinary shares (including ordinary shares represented by ADSs), assuming no exercise of the underwriters’ option to purchase additional ADSs and no exercise of outstanding options warrants offered and sold in this offering. Each member of our senior management and board of directors and their affiliates are subject to lock-up agreements with the underwriters that restrict their ability to transfer ordinary shares, options and other securities convertible into, exchangeable for, or exercisable for ordinary shares during the period ending on, and including, the 180th day after the date of this prospectus, subject to specified exceptions. Roth Capital Partners, LLC may, in its sole discretion, permit our shareholders who are subject to these lock-up agreements to sell securities prior to the expiration of the lock-up agreements. As of the date of this prospectus, the exercise of all outstanding options exercisable for ordinary shares would enable the subscription of new ordinary shares representing approximately            of the diluted share capital.

After the lock-up agreements pertaining to this offering expire, 94,302,045 additional ordinary shares will be eligible for sale in the public market, all of which ordinary shares are held by members of our senior management and board of directors and will be subject to volume limitations under Rule 144 under the Securities Act of 1933,

as amended, or the Securities Act. In addition, the ordinary shares subject to subscription under outstanding options exercisable for ordinary shares will become eligible for sale in the public market in the future, subject to certain legal and contractual limitations. Sales of a large number of the ordinary shares in the public market could depress the market price of the ADSs. See “Shares and American Depository Shares Eligible for Future Sale” for a more detailed description of sales that may occur in the future. If these additional ordinary shares are sold, or if it is perceived that they will be sold, in the public market, the trading price of the ordinary shares and ADSs could decline substantially, which could impair our ability to raise additional capital through the issuance of ordinary shares, ADSs or other securities in the future.

The dual listing of our ordinary shares and the ADSs following this offering may negatively impact the liquidity and value of the ADSs.

Following this offering and after the ADSs are listed on Nasdaq, our ordinary shares will continue to be listed on the ASX. We cannot predict the effect of this dual listing on the value of our ordinary shares and ADSs. However, the dual listing of our ordinary shares and ADSs may dilute the liquidity of these securities in one or both markets and may negatively impact the development of an active trading market for the ADSs in the United States. The price of the ADSs could also be negatively impacted by trading in our ordinary shares on the ASX.

We are subject to risks associated with currency fluctuations, and changes in foreign currency exchange rates could impact our results of operations.

Our ordinary shares are quoted in Australian dollars on the ASX and the ADSs will be quoted in U.S. dollars. In the past year, the Australian dollar has generally weakened against the U.S. dollar; however, this trend may not continue and may be reversed. As such, any significant change in the value of the Australian dollar may have a negative effect on the value of the ADSs in U.S. dollars. In addition, if the Australian dollar weakens against the U.S. dollar, then, if we decide to convert our Australian dollars into U.S. dollars for any business purpose, appreciation of the U.S. dollar against the Australian dollar would have a negative effect on the U.S. dollar amount available to us. To the extent that we need to convert U.S. dollars we receive from this offering into Australian dollars for our operations, appreciation of the Australian dollar against the U.S. dollar would have a negative effect on the Australian dollar amount we would receive from the conversion. Consequently, appreciation or depreciation in the value of the Australian dollar relative to the U.S. dollar would affect our financial results reported in U.S. dollar terms without giving effect to any underlying change in our business or results of operations. As a result of such foreign currency fluctuations, it could be more difficult to detect underlying trends in our business and results of operations.

Our ADS holders are not shareholders and do not have shareholder rights.

Deutsche Bank, as depositary, registers and delivers our American Depositary Shares, or ADSs. Our ADS holders will not be treated as shareholders and do not have the rights of shareholders. The depositary will be the holder of the shares underlying our ADSs. Holders of our ADSs will have ADS holder rights. A deposit agreement among us, the depositary and our ADS holders, and the beneficial owners of ADSs, sets out ADS holder rights as well as the rights and obligations of the depositary. New York law governs the deposit agreement and the ADSs. For a description of ADS holder rights, see “Description of American Depositary Shares” in this Registration Statement.

Our shareholders have shareholder rights. Australian law and our constitution govern shareholder rights. For a description of our shareholders’ rights, see “Memorandum and Articles of Association” in this Registration Statement. Shareholders are entitled to our notices of general meetings and to attend and vote at our general meetings of shareholders. At a general meeting, every shareholder present (in person or by proxy, attorney or representative) and entitled to vote has one vote on a show of hands. Every shareholder present (in person or by proxy, attorney or representative) and entitled to vote has one vote per fully paid ordinary share on a poll. This is subject to any other rights or restrictions which may be attached to any shares.

Our ADS holders do not have the same voting rights as our shareholders. ADS holders may exercise voting rights with respect to the underlying ordinary shares only in accordance with the provisions of the deposit agreement. Under the deposit agreement, ADS holders vote by giving voting instructions to the depositary. Upon receipt of instructions, the depositary will try to vote in accordance with those instructions. Otherwise, ADS holders will not be able to vote unless they withdraw the ordinary shares underlying their ADSs.

If we ask for our ADS holders’ instructions, the depositary will notify our ADS holders of the upcoming vote and arrange to deliver our voting materials and form of notice to them. The depositary will try, as far as practical, subject to Australian law and the provisions of the depositary agreement, to vote the shares as our ADS holders instruct. The depositary will not vote or attempt to exercise the right to vote other than in accordance with the instructions of the ADS holders. We cannot assure our ADS holders that they will learn of ordinary shareholders’ meetings and receive the voting materials in time to instruct the depositary or withdraw the underlying ordinary shares. This means that there is a risk that our ADS holders may not be able to exercise voting rights and there may be nothing they can do if their shares are not voted as they requested.

Our ADS holders do not have the same rights to receive dividends or other distributions as our shareholders.

Subject to any special rights or restrictions attached to a share, the directors may determine that a dividend will be payable on a share and fix the amount, the time for payment and the method for payment (although we have never declared or paid any cash dividends on our ordinary shares and we do not anticipate paying any cash dividends in the foreseeable future). Dividends may be paid on shares of one class but not another and at different rates for different classes. Dividends and other distributions payable to our shareholders with respect to our ordinary shares generally will be payable directly to them. Any dividends or distributions payable with respect to ordinary shares will be paid to the depositary, which has agreed to pay to our ADS holders the cash dividends or other distributions it or the custodian receives on shares or other deposited securities, after deducting its fees and expenses. Our ADS holders will receive these distributions in proportion to the number of shares their ADSs represent. In addition, there may be certain circumstances in which the depositary may not pay to our ADS holders amounts distributed by us as a dividend or distribution.

There are circumstances where it may be unlawful or impractical to make distributions to the holders of our ADSs.

The deposit agreement with the depositary generally requires the depositary to convert foreign currency it receives in respect of deposited securities into U.S. dollars and distribute the U.S. dollars to ADS holders, provided the depositary can do so on a reasonable basis. If it does not convert foreign currency, the depositary may distribute the foreign currency only to those ADS holders to whom it is possible to do so. If a distribution is payable by us in Australian dollars, the depositary will hold the foreign currency it cannot convert for the account of the ADS holders who have not been paid. It will not invest the foreign currency and it will not be liable for any interest. If the exchange rates fluctuate during a time when the depositary cannot convert the foreign currency, our ADS holders may lose some of the value of the distribution. The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADS holders. This means that our ADS holders may not receive the distributions we make on our shares or any value for them if it is illegal or impractical for us to make them available.

Risks Relating to Our Location in Australia

Australian takeovers laws may discourage takeover offers being made for us or may discourage the acquisition of large numbers of our shares.

We are incorporated in Australia and are subject to the takeover laws of Australia. Amongst other things, we are subject to the Corporations Act 2001 (Commonwealth of Australia). Subject to a range of exceptions, the Corporations Act prohibits the acquisition of a direct or indirect interest in our issued voting shares (including through the acquisition of ADSs) if the acquisition of that interest will lead to a person’s or someone else’s voting power in us increasing from 20% or below to more than 20% or increasing from a starting point that is above 20% and below 90%. Exceptions to the general prohibition include circumstances where the person makes a formal takeover bid for us, if the person obtains shareholder approval for the acquisition or if the person acquires less than 3% of the voting power of us in any rolling six-month period. Australian takeovers laws may discourage takeover offers being made for us or may discourage the acquisition of large numbers of our shares.

Holders of our ordinary shares or ADSs may have difficulty in effecting service of process in the United States or enforcing judgments obtained in the United States.

Holders of our ordinary shares or ADSs may have difficulties enforcing, in actions brought in courts in jurisdictions located outside the U.S., liabilities under U.S. securities laws. In particular, if such a holder sought to bring proceedings in Australia based on U.S. securities laws, the Australian court might consider:

•        that it did not have jurisdiction; and/or

•        that it was not an appropriate forum for such proceedings; and/or

•        that, applying Australian conflict of laws rule, U.S. law (including U.S. securities laws) did not apply to the relationship between holders of our ordinary shares or ADSs and us or our directors and officers; and/or

•        that the U.S. securities laws were of a public or penal nature and should not be enforced by the Australian court.

Holders of our ordinary shares and ADSs may also have difficulties enforcing in courts outside the U.S. judgments obtained in the U.S. courts against any of our directors and executive officers or us, including actions under the civil liability provisions of the U.S. securities laws.

As a foreign private issuer whose shares are listed on the Nasdaq Capital Market, we may follow certain home country corporate governance practices instead of certain Nasdaq requirements.

As a foreign private issuer whose shares are listed on the Nasdaq Capital Market, we are permitted to follow certain home country corporate governance practices instead of certain requirements of The Nasdaq Marketplace Rules. As an Australian company listed on the Nasdaq Capital Market, we may follow home country practice with regard to, among other things, the composition of the board of directors, director nomination process, compensation of officers and quorum at shareholders’ meetings. In addition, we may follow Australian law instead of the Nasdaq Marketplace Rules that require that we obtain shareholder approval for certain dilutive events, such as for the establishment or amendment of certain equity based compensation plans, an issuance that will result in a change of control of the company, certain transactions other than a public offering involving issuances of a 20% or more interest in the company and certain acquisitions of the shares or assets of another company. As a foreign private issuer that has elected to follow a home country practice instead of Nasdaq requirements. Accordingly, our shareholders may not be afforded the same protection as provided under Nasdaq’s corporate governance rules that are applicable to U.S. companies.

As a foreign private issuer, we are exempt from a number of rules under the U.S. securities laws and are permitted to file less information with the SEC than a U.S. company.

We are a foreign private issuer (as defined in the SEC’s rules) and, consequently, we are not subject to all of the disclosure requirements applicable to public companies organized within the United States. For example, we are exempt from certain rules under the Exchange Act that regulate disclosure obligations and procedural requirements related to the solicitation of proxies under the Exchange Act. In addition, our senior management and directors are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and related rules with respect to their purchases and sales of our securities. Moreover, while we currently make annual and semi-annual filings with respect to our listing on the ASX and expect to file financial reports on an annual and semi-annual basis, we will not be required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. public companies and will not be required to file quarterly reports on Form 10-Q or current reports on Form 8-K under the Exchange Act. In addition, foreign private issuers are not required to file their annual report on Form 20-F until four months after the end of each fiscal year. Accordingly, there may be less publicly available information concerning our company than there would be if we were not a foreign private issuer.

Industry and Market Data

This prospectus contains estimates and information concerning our industry and our business, including estimated market size and projected growth rates of the markets for our drug candidates. Unless otherwise expressly stated, we obtained this industry, business, market, medical and other information from reports, research surveys, studies and similar data prepared by third parties, industry, medical and general publications, government data and similar sources.

This information involves a number of assumptions and limitations. Although we are responsible for all of the disclosure contained in this prospectus and we believe the third-party market position, market opportunity and market size data included in this prospectus are reliable, we have not independently verified the accuracy or completeness of this third-party data. In addition, projections, assumptions and estimates of our future performance and the future performance of the industry in which we operate are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in “Risk Factors.” These and other factors could cause results to differ materially from those expressed in these publications and reports.

Use of Proceeds

We estimate that the net proceeds to us from the sale of            ADSs in this offering will be approximately US$             million (or approximately US$           million if the underwriter exercises its option to purchase additional ADSs in full), based on the assumed initial public offering price of US$           per ADS, after giving effect to, the ADS-to-ordinary share ratio of 1-to-50, after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

Each US$1.00 increase (decrease) in the assumed initial offering price of US$           per ADS, after giving effect to the ADS-to-ordinary share ratio of 1-to-50, would increase (decrease) the net proceeds to us from this offering by approximately US$           million, assuming the number of ADSs offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. Similarly, an increase (decrease) of 1,000,000 ADSs offered by us would increase (decrease) the net proceeds to us by US$           million, assuming the assumed initial public offering price of US$           per ADS, after giving effect to the ADS-to-ordinary share ratio of 1-to-50, remains the same and after deducting underwriting discounts and commissions.

We expect to use the net proceeds from this offering, together with our existing cash, to further our clinical trials, for working capital and other general corporate purposes. However, due to the uncertainties inherent in the product development process, it is difficult to estimate with certainty the exact amounts of the net proceeds from this offering that may be used for the above purposes. Our management will have broad discretion over the use of the net proceeds from this offering. The amounts and timing of our expenditures will depend upon numerous factors including the results of our research and development efforts, the timing and success of preclinical studies and any ongoing clinical trials or clinical trials we may commence in the future, the timing of regulatory submissions and the amount of cash obtained through future collaborations, if any.

We believe opportunities may exist from time to time to expand our current business through acquisitions or in-licensing of complementary companies, medicines or technologies. While we have no current agreements, commitments or understandings for any specific acquisitions or in-licensing at this time, we may use a portion of the net proceeds for these purposes.

As of December 31, 2020, we had cash of A$11,840,308 (or US$9,119,405). We believe our cash, together with the net proceeds of this offering, will be sufficient to fund our operations until         . In particular, we estimate that such funds, together with such existing cash, will be sufficient to enable us to advance our clinical trials.

Pending our use of the net proceeds from this offering, we intend to invest the net proceeds in a variety of capital preservation investments, including short-term, investment-grade, interest-bearing instruments.

Dividend Policy

We have never declared or paid any dividends on our ordinary shares. We intend to retain any earnings for use in our business and do not currently intend to pay cash dividends on our ordinary shares. Dividends, if any, on our outstanding ordinary shares will be declared by and subject to the discretion of our board of directors, and subject to Australian law.

Any dividend we declare will be paid to the holders of ADSs, subject to the terms of the deposit agreement, to the same extent as holders of our ordinary shares, to the extent permitted by applicable law and regulations, less the fees and expenses payable under the deposit agreement. Any dividend we declare will be distributed by the depositary bank to the holders of the ADSs, subject to the terms of the deposit agreement. See “Description of American Depositary Shares — Dividends and Other Distributions.”

Capitalization

The following table sets forth our cash and our capitalization as of December 31, 2020, on:

•        an actual basis; and

•        an as adjusted basis to give effect to the issuance and sale of            ADSs in this offering at the assumed initial public offering price of US$           per ADS, and an ADS-to-ordinary share ratio of 1-to-50, after deducting underwriting discounts and commissions and estimated offering expenses payable by us.

You should read this information in conjunction with our consolidated financial statements and the related notes included elsewhere in this prospectus, the information set forth in “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other financial information contained elsewhere in this prospectus.

____________

(1)      The as adjusted statement of financial position data give effect to our receipt of net proceeds from the issuance and sale of ADSs at the assumed initial offering price of            US$ per ADS, and an ADS-to-ordinary share ratio of 1-to-50, after deducting underwriting commissions and estimated offering expenses payable by us.

(2)      Each US$1.00 increase (decrease) in the assumed initial public offering price of US$           per ADS, after giving effect to the ADS-to-ordinary share ratio of 1-to-50, would increase (decrease) each of cash, contributed equity, total equity and total capitalization by A$           million (or US$           million), assuming the number of ADSs offered by us, as set forth on the cover page of this prospectus, remains the same, and after deducting underwriting discounts and commissions and estimated offering expenses payable by us. Similarly, an increase (decrease) of 1,000,000 ADSs offered by us would increase (decrease) each of cash, contributed equity, total equity and total capitalization by A$           million (or US$           million), assuming the assumed initial public offering price of US$           per ADS, after giving effect to the ADS-to-ordinary share ratio of 1-to-50, remains the same, and after deducting underwriting discounts and commissions. The as adjusted information is illustrative only and will depend on the actual initial public offering price, number of ADSs offered and other terms of this offering determined at pricing.

The outstanding ordinary share information in the table above is based on 1,040,136,110 ordinary shares outstanding as of December 31, 2020, and excludes:

•        334,855,128 ordinary shares issuable upon the exercise of outstanding options as of December 31, 2020 with a weighted-average exercise price of A$0.11 per ordinary share; and

•        23,287,265 ordinary shares issuable upon exercise of performance rights.

Dilution

If you invest in the ADSs in this offering, your ownership interest will be immediately diluted to the extent of the difference between the initial public offering price per ADS and the as adjusted net tangible book value per ordinary share or ADS immediately after this offering.

As of December 31, 2020, our historical net tangible book value was A$11,802,503 (or US$9,090,288), or A$             (or US$          ) per ADS. Historical net tangible book value per ADS represents our total tangible assets less total liabilities, divided by the number of ordinary shares outstanding as of December 31, 2020, converted to ADSs at an ADS-to-ordinary share ratio of 1-to-50.

After giving effect to the receipt of the net proceeds from our sale of              ADSs in this offering at an assumed initial public offering price of US$             per ADS, after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of December 31, 2020 was A$             million (or US$             million), or A$             (or US$             ) per ADS, equivalent to A$             (or US$            ) per ordinary share, in each case based on an ADS-to-ordinary share ratio of 1-to-50. This represents an immediate increase in net tangible book value of A$             (or US$            ) per ADS, equivalent to A$             or (US$            ) per ordinary share, to our existing shareholders and immediate dilution of A$             (or US$            ) per ADS, equivalent to A$             (US$            ) per ordinary share, to investors purchasing ADSs in this offering, in each case based on an ADS-to-ordinary share ratio of 1-to-50.

The following table illustrates this dilution on a per ADS basis, assuming all ordinary shares outstanding as of December 31, 2020 converted to ADSs at an ADS-to-ordinary share ratio of 1-to-50:

Each US$1.00 increase (decrease) in the assumed initial public offering price of US$             per ADS, after giving effect to the ADS-to-ordinary share ratio of 1-to-50, would increase (decrease) the as adjusted net tangible book value per ADS after this offering by US$           and dilution to investors in this offering by US$             per ADS, assuming that the number of ADSs offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting underwriting discounts and commissions. An increase of 1,000,000 ADSs offered by us would increase the as adjusted net tangible book value by US$             per ADS and the dilution to investors in this offering would decrease by US$             per ADS, assuming the assumed initial public offering price remains the same and after deducting underwriting discounts and commissions. A decrease of 1,000,000 ADSs offered by us would decrease the as adjusted net tangible book value by US$             per ADS and the dilution to investors in this offering would increase by US$           per ADS, assuming the assumed initial public offering price remains the same and after deducting underwriting discounts and commissions.

If the underwriter exercises its option to purchase             additional ADSs in full, the as adjusted net tangible book value after the offering would be US$             per ADS, the increase in net tangible book value per ADS to existing shareholders would be US$             per ADS and the dilution per ADS to new investors in this offering would be US$             per ADS, in each case assuming an initial public offering price of US$             per ADS, after giving effect to the ADS-to-ordinary share ratio of 1-to-50.

The dilution information above is for illustration purposes only. Our as adjusted net tangible book value following the closing of this offering will depend on the actual initial public offering price and other terms of this offering determined at pricing.

The following table summarizes, as of December 31, 2020:

•        the total number of ordinary shares purchased from us by existing shareholders and the equivalent number of ordinary shares underlying ADSs purchased by investors in this offering;

•        the total consideration paid to us by our existing shareholders and by investors purchasing ADSs in this offering, assuming an initial public offering price of US$             per ADS, after giving effect to the ADS-to-ordinary share ratio of 1-to-50, before deducting underwriting discounts and commissions and estimated offering expenses payable by us in connection with this offering; and

•        the average price per ordinary share paid by existing shareholders and the average price per ADS or equivalent number of ordinary shares.

If the underwriter exercises its option to purchase            additional ADSs in full, our existing shareholders would own         % and investors in this offering would own         % of the total number of ordinary shares outstanding (including shares underlying ADSs) upon the closing of this offering.

Each US$1.00 increase (decrease) in the assumed initial public offering price of US$         per ADS, after giving effect to the ADS-to-ordinary share ratio of 1-to-50, would increase (decrease) the total consideration paid by investors in this offering by US$         million and increase (decrease) the total consideration paid by investors in this offering by         %, assuming that the number of ADSs offered by us, as set forth on the cover page of this prospectus, remains the same and before deducting underwriting discounts and commissions.

The outstanding ordinary share information in the table above is based on 1,040,136,110 ordinary shares outstanding as of December 31, 2020, and excludes:

•        334,855,128 ordinary shares issuable upon the exercise of outstanding options as of December 31, 2020 with a weighted-average exercise price of A$0.11 per ordinary share; and

•        23,287,265 ordinary shares issuable upon exercise of performance rights.

To the extent any outstanding options are exercised, there will be further dilution to investors purchasing in this offering.

Overview

We are a development stage enterprise at an early stage in the development of our drug candidate. We have incurred net losses since inception and expect to incur substantial and increasing losses for the next several years as we expand our research and development activities and move our drug candidate into later stages of development. The process of carrying out the development of our drug candidates to later stages of development may require significant additional research and development expenditures, including pre-clinical testing and clinical trials, as well as for obtaining regulatory approval. To date, we have funded our operations primarily through the sale of equity securities, proceeds from the exercise of options, grants and interest income

The financial statements for fiscal year 2020, 2019 and for the half-year report ended on December 31, 2020 and 2019 are presented without the consolidation of the Company’s wholly-owned subsidiary which was sold on June 30, 2020.

Liquidity and Capital Resources

Since our inception, our operations have mainly been financed through the issuance of equity securities. Additional funding has come through interest earned from cash on term deposit.

Equity Issuances

The following table summarizes our issuances of ordinary shares for cash, share-based payments and executive and employee compensation in the last two fiscal years.

Capital Requirements

As of December 31, 2020, we had year-end cash of A$11,840,308. We anticipate that our current cash will be sufficient to fund our operations for more than 12 months from the date of this filing. However, our forecast of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement that involves risks and uncertainties, and actual results could vary materially. If we are unable to raise additional capital when required or on acceptable terms, we may have to significantly delay, scale back or discontinue one or more of our clinical trials or our operations.

We anticipate that we will require substantial additional funds in order to achieve our long-term goals and complete the research and development of our current drug candidates. We do not expect to generate significant revenue until we obtain regulatory approval to market and sell our drug candidate and sales of our drug candidate have commenced. We therefore expect to continue to incur substantial losses in the near future.

Our future capital requirements are difficult to forecast and will depend on many factors, including but not limited to:

•        the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;

•        the scope, results and timing of preclinical studies and clinical trials;

•        the costs and timing of regulatory approvals; and

•        the costs of establishing sales, marketing and distribution capabilities.

Critical Accounting Policies and Estimates

The preparation of the consolidated financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts in the financial statements. Management continually evaluates its judgements and estimates in relation to assets, liabilities, contingent liabilities, revenue and expenses. Management bases its judgements, estimates and assumptions on historical experience and on other various factors, including expectations of future events, management believes to be reasonable under the circumstances. The resulting accounting judgements and estimates will seldom equal the related actual results. The judgements, estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed here below.

Coronavirus (COVID-19) pandemic

Judgement has been exercised in considering the impacts that the COVID-19 pandemic has had, or may have, on the consolidated entity based on known information. This consideration extends to the nature of the products and services offered, customers, supply chain, staffing and geographic regions in which the consolidated entity operates. Other than as addressed in specific notes, there does not currently appear to be either any significant impact upon the financial statements or any significant uncertainties with respect to events or conditions which may impact the consolidated entity unfavorably as at the reporting date or subsequently as a result of the COVID-19 pandemic.

Share-based payment transactions

The consolidated entity measures the cost of equity-settled transactions with employees and third parties by reference to the fair value of the equity instruments at the date at which they are granted. The fair value is determined by using either the trinomial or Black-Scholes model taking into account the terms and conditions upon which the instruments were granted. The accounting estimates and assumptions relating to equity-settled share-based

Business

Overview

Our legal name is Incannex Healthcare Limited (“Incannex”). We were incorporated in Australia in April 2001 under the name Mount Magnet South Limited. In November 2016, we changed our name to Impression Healthcare Limited, and in June 2020, to Incannex Healthcare Limited. Incannex is listed on the ASX under the symbol “IHL.”

Strategy

Our mission is to create premier ethical pharmaceutical drugs and therapies for patients with unmet medical needs, in all instances fulfilling regulatory requirements of the Food and Drug Administration (“FDA”) and other relevant regulatory agencies (EMEA, TGA). We aim to be recognized as a leading specialty drug development company, committed to restoring health and transforming the lives of patients through the development of novel pharmaceutical products and treatments.

We develop targeted and scientifically validated fixed-dose combinations of synthetic cannabinoids and psychedelic agents, applying proprietary insights in an effort to create long term value for our patients and shareholders. We focus on clinical indications that we believe represent unmet or inadequately addressed medical needs and also represent compelling commercial opportunities. In particular, we are developing three unique pharmaceutical compositions to target five indications: obstructive sleep apnea (“OSA”), traumatic brain injury (“TBI”)/concussion, rheumatoid arthritis, inflammatory bowel disease and inflammatory lung conditions (“ARDS”, “COPD”, Asthma, Bronchitis). We are also developing a treatment for generalized anxiety disorder (“GAD”) utilising psilocybin combined with innovative psychotherapy methods. We are pursuing FDA registration and marketing approval for each product and therapy under development.

Additionally, we seek to secure patents on our drug candidates in conjunction with our medical and scientific staff, advisors and the investigators of our research studies that constitute our advisory board. Our advisory board is comprised of industry and academic experts familiar with our business, and we meet with the advisory board regularly. The current members of our advisory board are Dr. Sud Agarwal (our Chief Medical Officer and Director), Mark Bleakley (our Head of Programs), Rosemarie Walsh (our Clinical Research Manager), Terrance O’Brien (principal investigator of the IHL-42X from Alfred Hospital), Dr Jennifer Walsh (professor at University of Western Australia), Ron Jithoo (neurosurgeon and advisor for IHL-216), and Paul Liknaitsky (psychedelic principal investigator from Monash University). Our advisory board also comprises our collaborative partners, and in particular Monash University, The Alfred Hospital and the University of Western Australia Centre for Sleep Science.

To achieve our goals, we intend to:

•        Advance our novel investigational drug candidates towards approval in the United States and elsewhere.    We are pursuing FDA approval of all our drug candidates currently in development. All preclinical and clinical trials are structured to ensure that each program is FDA compliant. We will be pursuing a New Drug Application (“NDA”) with the FDA with respect to each of our drug candidates. If the NDA is approved, the product may be marketed in the United States. Once an NDA for one of our drug candidates is approved in the United States, we plan to pursue marketing approval of our drug candidates in other regions including the Europe Union, Japan, Australia and Israel.

•        Take advantage of accelerated commercialization pathway options for our drug candidates.    We and our regulatory consultants believe that each of our drug candidates will qualify for one or more FDA expedited review programs (breakthrough designation, accelerated approval, priority review and/or fast track), as there are a limited amount of pharmaceutical drug treatments approved in the U.S. to treat the indications that we are targeting with our drug candidates, and the pharmaceutical treatments that do exist provide limited treatment and are costly. These expedited review programs often result in accelerated and less-costly regulatory pathways to approval compared with traditional regulatory pathways.

•        Develop future clinical products targeting unmet medical needs.    We intend to only develop clinical products that treat unmet medical conditions. As a result, we may have opportunities to accelerate commercialization of such products.

•        Maintain a strong intellectual property portfolio.    We have developed a global intellectual property strategy to support our commercial objectives. We are monitoring the results of our research and development programs to identify new intellectual property that aligns with those commercial objectives. We intend to take a global approach to our intellectual property strategy and we intend to pursue patent protection in key global markets, including the United States, Europe, Japan and Israel. We have pending patent applications relating to our drug candidates IHL-42X, IHL-216A and IHL-675A. This approach aligns with our regulatory strategy, including the proposed submission of Pre-Investigational New Drug Application (“pre-IND”) meeting requests to the FDA for our clinical programs.

Clinical Approach

We are pursuing FDA approval of all our drug candidates currently being developed. We will be working with the FDA to ensure each clinical program is structured to be FDA compliant. FDA approval will be sought following the completion of successful phase 3 studies. Once we receive FDA approval for our drug candidates, we will be able to commercialize our drug candidates in the United States and pursue regulatory approval for the drug prescription in other jurisdictions, including the European Union, Japan, Australia and Israel. The graphic here below represents our clinical development pipeline and estimated timelines until the receipt of FDA pre-IND advice and the opening of INDs for each research program.

Market Opportunity

The combined annual global market size of the indications we are targeting is over US$110 billion, which is derived from the total addressable market for the treatment of OSA, TBI, concussions, rheumatoid arthritis, inflammatory bowel disease, inflammatory lung conditions (ARDS, COPD, Asthma, Bronchitis) and GAD. Thus, there is significant economic potential to shareholders, as well as benefit to patients suffering from untreated medical conditions.

Our Drug Candidates

IHL-42X

Obstructive Sleep Apnea

Obstructive sleep apnea is characterized by a narrowing or obstruction of the upper airway in sleep, interfering with breathing and interrupting sleep. This relatively common and chronic disorder is underdiagnosed and inadequately treated. It is understood to contribute to a wide range of serious long-term outcomes, including cardiovascular disease, cognitive impairments such as memory loss, poor concentration and judgment, depression and death or injury due to traffic accidents resulting from excessive daytime sleepiness. The costs associated with OSA are substantial, relating to lost productivity, workplace and motor vehicle accidents.

A 2019 article published by the Lancet premised on literature-based analysis of 17 studies across 16 countries, estimated that OSA affects some 936 million adults worldwide. This alarming statistic is also thought to be increasing due to growing prevalence of obesity and an ageing global population. Many people with OSA develop high blood pressure (hypertension), which can increase the risk of cardiovascular disease. The more severe the OSA, the greater the risk of coronary artery disease, heart attack, heart failure and stroke.

There are no registered drugs for OSA. Current treatment options include: continuous positive airway pressure (“CPAP”) in which an external device pneumatically splints the airway open to prevent disruptions in breathing; oral appliances to advance the mandible or to retain the tongue, putting the mouth in a position more conducive to breathing; surgery to remove physical obstructions to air flow; and implantable electronic stimulators to activate muscles at the base of the tongue, opening the airway in synchrony with respiration. However, all of these therapies are inadequate, expensive, and for implantable stimulators and surgery, invasive.

The standard treatment option is the mechanical CPAP device, however, we believe patient compliance to CPAP devices is low due to discomfort and claustrophobia resulting from pressurized air being pumped into the patient’s nose and/or mouth during sleep. Despite these discomforts, the global annual market for OSA detection and treatment using CPAP devices is over US$10 billion and growing.

IHL-42X in Obstructive Sleep Apnea

IHL-42X is a fixed-dose combination of acetazolamide, a registered pharmaceutical, and dronabinol, a synthetic cannabidiol; both agents have been shown to reduce the apnea hypopnea index (“AHI”). We believe that the activity of synthetic dronabinol on cannabinoid receptors causes dilation of the airway, and acetazolamide induces modest metabolic acidosis, signalling to the body that there is excess CO2 in the blood, thus increasing respiration. By exploiting two mechanisms that both reduce AHI in one pharmaceutical formulation, we believe that IHL-42X can have a therapeutic benefit at doses of each constituent drug that are safe and tolerable.

Australian Stage 2 Clinical Trial for IHL-42X for Obstructive Sleep Apnoea (“OSA”)

We are currently conducting a proof-of-concept Phase 2 clinical trial in Australia to support our IND application with the FDA and to inform the clinical design of our planned FDA compliant pivotal Phase 2 clinical trial in Australia to assess the safety and efficacy of IHL-42X in patients with Obstructive Sleep Apnea. We received approval from The Alfred Hospital Human Research Ethic’s Committee in September 2020 to proceed with the trial in Australia. In December 2020, we recruited the first patients to the randomized, double-blind, placebo-controlled clinical trial that assesses the therapeutic benefit of IHL-42X at three different doses. The primary endpoint of the

trial is the measurement of reduction in the AHI and the secondary endpoints are reduction in oxygen desaturation index (“ODI”), daytime somnolence measured by the Epworth Sleepiness Scale, improvement in mood as measured by the POMS (Profile of Moods State), and well-being as measured by the Short Form 36 and the safety of the IHL-42X combination will be established through adverse event monitoring.

The study is currently underway and well-advanced at the Alfred Hospital in Melbourne Australia and the University of Western Australia Centre for Sleep Science in Perth. We have retained Novotech, a global contract research organization, to manage and to monitor the study. In July 2021, an interim analysis of the data from our ongoing phase 2b double blind randomised placebo-controlled clinical trial was performed and these results have been utilized to support a patent application regarding the methods for the treatment of obstructive sleep apnoea. Additionally, we plan to supply IHL-42X for sale in Australia under the Special Access Scheme for unregistered medicinal synthetic cannabidiol products after the completion of the Phase 2 study and prior to drug registration.

IHL-216A

IHL-216A for Concussion/Traumatic Brain Injury and Chronic traumatic encephalopathy

Concussion/Traumatic Brain Injury are caused by a rapid acceleration/deceleration of the brain caused by a direct blow to the head or sudden impact to the body that jolts the skull. This causes the brain to compress against the skull. The impact of the brain against the skull causes both macro and micro scale damage to the brain which sets of a series of physiological events called secondary injury cascades. These secondary injury cascades are what cause many of the neurocognitive deficits seen in TBI patients.

Falls, vehicle collisions, violence, sports and combat injuries are the main activities leading to TBI and concussion. The signs and symptoms of a concussion can be subtle and may not show up immediately. Symptoms can last for days, weeks or even longer. Common symptoms after a concussive traumatic brain injury are headache, loss of memory (amnesia) and confusion. The amnesia usually involves forgetting the event that caused the concussion. Other symptoms include nausea, vomiting, fatigue, blurry vision and ringing in the ears.

Complications can occur immediately or soon after a traumatic brain injury. Severe injuries increase the risk of a greater number of and more-severe complications. Moderate to severe traumatic brain injury can result in prolonged or permanent changes in a person’s state of consciousness, awareness or responsiveness. Many people who have had a significant brain injury will experience changes in their cognitive ability, have executive functioning problems and or communication, emotional and behavioral problems. Some research suggests that repeated or severe traumatic brain injuries might increase the risk of degenerative brain diseases, but this risk cannot be predicted for an individual.

Chronic traumatic encephalopathy (“CTE”) is the term used to describe brain degeneration likely caused by repeated head traumas. CTE is a diagnosis made only at autopsy by studying sections of the brain. CTE is a rare disorder that is not yet well understood. CTE is not related to the immediate consequences of a late-life episode of head trauma. CTE has a complex relationship with head traumas such as persistent post-concussive symptoms and second impact syndrome that occur earlier in life.

Experts are still trying to understand how repeated head traumas, including how many head injuries and the severity of those injuries, and other factors might contribute to the changes in the brain that result in CTE.

CTE has been found in the brains of football players, boxers and other athletes that play contact sports, along with military personnel who were exposed to explosive blasts. Some signs and symptoms of CTE are thought to include difficulties with thinking (cognition) and emotions, physical problems and other behaviors. Symptoms of CTE often manifest decades after head trauma occurs.

CTE cannot be made as a diagnosis during life except in those rare individuals with high-risk exposures. Researchers do not yet know the frequency of CTE in the population and do not understand the causes. There is no cure for CTE. Researchers are currently developing diagnostic biomarkers for CTE, but none have been validated yet.

IHL-216A Formulation development for clinical trials

IHL-216A is a fixed dose combination of isoflurane, a registered pharmaceutical, and CBD, intended for administration in the immediate period after primary blunt head injury to prevent development of brain injuries. Isoflurane is approved in the United States for induction and maintenance of anaesthesia. CBD is approved for use in seizure disorders and has shown effects on neuroinflammatory responses to brain injury. Isoflurane is a registered pharmaceutical, and also has demonstrated neuroprotective activity (neuroprotective activity, or neuroprotection, is defined as reduced neuronal cell death or disruption) in animal studies of TBI such as modulating glutamate release and calcium uptake as well as effects on mitochondrial membrane depolarization and excitatory neurotransmission. Thus, we believe that IHL-216A may affect neuroexcitation, neuro-inflammation, cerebral blood flow and cerebral oxygen consumption resulting in overall neuroprotection. We are also assessing its ability to protect the brain against secondary injury mechanisms that cause neuronal cell death and raised intracranial pressure in the days and weeks following head trauma in sports, and all other applicable scenarios resulting in head trauma (falls, vehicle collisions, violence, combat, among other causes). Ablating secondary brain injury may improve positive outcomes for long term neurological sequelae, including CTE, a major health risk associated with contact sports.

The formulation of IHL-216A presents unique challenges. Because isoflurane is an inhaled volatile anesthetic, it cannot be used in a typical oral drug combination product. We intend to formulate IHL-216A as a combined inhalational product delivered via a nebulizer. Nebulized drug delivery involves using air pressure or ultrasonic vibrations to turn a liquid drug solution into an aerosol. We engaged Vectura, a UK based contract development and manufacturing organization, to develop the nebulised CBD formulation and device for delivery of the CBD to the isoflurane anaesthetic circuit. Development of the nebulized CBD formulation will be an iterative process starting with three steps of refinement based on properties of the solution, generated aerosol and dose delivery. Vectura specializes in the development of inhaled drugs and has an excellent track record of bringing products to market and have formulated pharmaceutical drugs for multinational pharmaceutical companies including Bayer, Sandoz and Novartis.

Appointing Vectura to develop the IHL-216A formulation in parallel with the animal study using the NFL model of concussion will ensure that we are readied with the specific formulation and delivery mechanism required for advancement of a pivotal Phase 2 clinical trial once the Stage 2 in vivo study and formulation is finalized.

Due to the product’s potential therapeutic utility in contact sports, IHL216A is being designed to satisfy the World Anti-doping Authority (“WADA”) specifications for use by athletes at risk of TBI and CTE.

Stage 1 pre-clinical study for IHL-216A for TBI and CTE

In December 2020, we completed an animal study to formally assess the neuroprotective capability of IHL-216A. The study introduced rodents to head trauma in a highly controlled manner to inflict a reproducible injury. Various doses of IHL-216A or its active pharmaceutical ingredients were administered to eight cohorts of rodents soon after traumatic head injury. Behavioral tests were used to assess the neurocognitive and motor function over time. We also monitored secondary injury cascades, assessed structural damage to the brain using magnetic resonance imaging and performed micro-scale cellular analysis post-mortem to discern and compare neuronal damage across the cohorts.

As detailed below, we found that the IHL-216A components, CBD and isoflurane, act synergistically to reduce indicators of neuronal damage, neuroinflammation and behavioral deficits that are consequences of TBI, as IHL-216A outperformed the predicted effect of CBD and isoflurane combined. The predicted result is determined by analyzing the results of isoflurane and CBD independently, and then based on those results predicting how well the drugs would do on a combined basis; to the extent IHL-216A exceeds the predicted result, we can conclude that the drugs strengthen the effectiveness of one another and synergies exist. The study also found that IHL-216A was significantly more effective than CBD or isoflurane applied on a standalone basis.

Post-mortem analysis of rat brains also detected synergy between CBD and isoflurane. Brains were fixed and sectioned prior to Nissl staining to identify neuronal damage. Nissl staining is a microscopy technique to visual Nissl bodies. Healthy neurons typically have more Nissl bodies than damaged ones. Neuronal damage is indicated by the ratio of Nissl bodies to neurons across different sections of the hippocampus with a lower Nissl/neuron ratio indicative of increased neuronal damage. Synergy between CBD and isoflurane was detected in hippocampal regions

cornu ammonis 1 (CA1) and cornu ammonis 2 (CA2). These regions of the brain are known to be important in the formation and storage of memories. In the study, IHL-216A outperformed CBD alone by 53% for CA1 and 60% for CA2, outperformed isoflurane alone by 28% for CA1 and 145% for CA2, and outperformed the predicted effect of CBD and isoflurane combined by 20% for CA1 and 53% for CA2. These results demonstrated less neuronal damage experienced by the rats treated with IHL-216A relative to the predicted value.

Figure 1. Synergistic activity of CBD and isoflurane (IHL-216A) in neuronal damage as assessed by Nissl staining.    Rodents that had undergone TBI and treated with CBD and/or isoflurane or vehicle were assessed for neuronal damage by post-mortem analysis of fixed brain sections by Nissl staining. Nissl staining permits the quantitation of the ratio of Nissl bodies to total neurons, a lower ratio being indicative of increased neuronal damage. The Nissl/neuron ratio observed in hippocampal regions (A) CA1 and (B) CA2 contralateral to the site of injury in the group treated with IHL-216A was greater than that predicted based on the groups treated with each drug alone, which is indicative of synergy. Values are average of the respective treatment group. Group sizes: Uninjured n=6, vehicle n=6, CBD n=6, isoflurane n=5, IHL-216A n=6. Neuroinflammation Marker — Iba1.

A post-mortem analysis of the rat brains also determined that CBD and isoflurane were synergistic in reducing levels of the neuroinflammation marker Iba1 as detected using immunofluorescence. Iba1 is a protein expressed in microglia, a type of innate immune cell in the brain, that is an established marker of microglial activation and neuroinflammation. The levels of Iba1 in the brain are detected using immunofluorescence, which is a microscopy technique that employs antibodies specific to Iba1 which are detected using a fluorescent tag. Increased levels of Iba1 are indicative of increased neuroinflammation. IHL-216A reduced the Iba1 neuroinflammation marker by 35% more than CBD alone and 123% more than isoflurane administered alone. IHL-216A also reduced the Iba1 neuroinflammation marker by 10% more than the predicted value of the combined CBD and isoflurane.

Figure 2. Synergistic activity of CBD and isoflurane (IHL-216A) in reducing levels of the neuroinflammatory marker Iba1.    Rodents that had undergone TBI and treated with CBD and/or isoflurane or vehicle were assessed for neuroinflammation through immunofluorescence analysis of the neuroinflammatory marker Iba1. Iba1 levels increase after TBI and a reduction in Iba1 is indicative of a reduction in neuroinflammation. Iba1 levels in brain sections ipsilateral to the site of injury in the group treated with IHL-216A were reduced more than would be predicted based on the reduction observed in groups treated with each drug alone, which is indicative of synergy. Values are average of the respective treatment group. Group sizes: Uninjured n=6, vehicle n=5, CBD n=6, isoflurane n=3, IHL-216A n=5.

Synergy between CBD and isoflurane was detected in the behavioral outcomes assessed using the Morris Water Maze. In the Morris Water Maze animals are trained to find a platform in a pool of water. After a number of training sessions, the platform is removed and the mice are monitored to determine whether they return to the location of the platform, which is a measure of spatial learning and memory. IHL-216A outperformed the predicted value of combined CBD and isoflurane when assessing both the number of times rats returned to the location of the platform per group by 87% as well as the proportion of rats in the group that returned to the location of the platform by 24%, demonstrating the synergistic effect of CBD and isoflurane.

Figure 3. Synergistic activity of CBD and isoflurane (IHL-216A) in the Morris Water Maze assessment. Rodents that had undergone TBI and treated with CBD and/or isoflurane or vehicle were assessed for spatial learning and memory using the Morris Water Maze. The observed performance with respect to both (A) relative instances of animal in platform location and (B) proportion of animals in that reached the platform location was better in the group treated with the CBD isoflurane combination (IHL-216A) than what was predicted based on the performance of the groups treated with each drug alone. This outperformance by the IHL-216A compared to the predicted performance is indicative of synergy. Values are average of the respective treatment group. Group sizes: Uninjured n=6, vehicle n=6, CBD n=5, isoflurane n=6, IHL-216A n=6.

Stage 2 pre-clinical study for IHL-216A

We are currently undertaking a second and more-extensive animal study on the protective effect of IHL-216A in sports concussion with the Monash Trauma Group at the Department of Neuroscience, Monash University, Australia.

The Monash Trauma Group consists of a team of leading scientists within their respective fields. Their research focuses on the effects, underlying pathophysiological mechanisms, biomarkers, and treatments of trauma related conditions including TBI and concussion as well as other types of neurological diseases, including CTE.

The study is coordinated by Dr Stuart McDonald, an expert in fluid biomarker development for monitoring TBI, Associate Professor Richelle Mychasiuk, an expert in animal models of TBI and their clinical relevance, and Associate Professor Sandy Shultz, an expert in the pathological mechanisms, biomarkers and treatments of TBI and related conditions.

The model of TBI being used in this study was developed by Monash University in collaboration with the US National Football League (“NFL”). The results of the study will be used as a precursory data set to inform the pivotal clinical trials required for drug registration.

IHL-675A

IHL-675A comprises a combination of hydroxychloroquine, a registered pharmaceutical, and CBD. Hydroxychloroquine (HCQ) is a disease modifying anti-rheumatic drug that regulates the activity of the immune system, which may be overactive in some conditions. HCQ can modify the underlying disease process, rather than simply treating the symptoms. We have demonstrated that IHL-675A components, cannabidiol and hydroxychloroquine, act synergistically to inhibit production of key inflammatory cytokines in an in vitro study and in 4 distinct successful in vivo experiments using established models of inflammation. We are able to determine whether synergies exist in IHL-675A studies by comparing the predicted result of CBD and HCQ acting together to the actual IHL-675A results. The predicted result is determined by analyzing the results of HCQ and

CBD independently in the study, and then based on those results predicting how well the drugs would do on a combined basis; to the extent IHL-675A exceeds the predicted result, we can conclude that the drugs strengthen the effectiveness of one another and synergies exist.

We have evaluated the results of these experiments and believe IHL-675A to be a multi-use candidate for the prevention and treatment of inflammatory lung conditions (ARDS, COPD, asthma, and bronchitis), rheumatoid arthritis and inflammatory bowel diseases. Potentially, this could mean that IHL-675A is a better alternative to CBD based products for certain inflammatory diseases, subject to further examination.

We have completed a pre-IND meeting with the FDA to discuss the regulatory pathway for the development of IHL-675A for lung inflammation in the United States and plan to open INDs for each of the three indications. FDA agreed that marketing applications for IHL-675A should be 505(b)(2) applications due to the existence of certain safety and efficacy information on the active ingredients of IHL-675A originating from historical studies that we are entitled to use in a new drug application.

Lung Inflammation (COPD, Asthma, ARDS and Bronchitis)

Chronic obstructive pulmonary disease (“COPD”) is a chronic inflammatory lung disease that causes obstructed airflow from the lungs. Symptoms include breathing difficulty, cough, mucus (sputum) production and wheezing. It is typically caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. People with COPD are at increased risk of developing heart disease, lung cancer and a variety of other conditions.

Asthma is a condition in which inflammation causes the airways to narrow and swell and which may cause the patient to produce extra mucus. This can make breathing difficult and trigger coughing, a whistling sound (wheezing) during breathing and shortness of breath. For some people, asthma is a minor nuisance. For others, it can be a major problem that interferes with daily activities and may lead to a life-threatening asthma attack. According to Allied Market Research, the Global COPD and asthma drug market is expected to reach US$50.4 billion by 2022, growing at a CAGR of 3.7% from 2016 to 2022.

Acute respiratory distress syndrome (“ARDS”) occurs when fluid builds up in the air sacs (alveoli) located in the lungs. The fluid prevents oxygen from reaching the bloodstream. This deprives organs of the oxygen they need to function. ARDS typically occurs in people who are already critically ill or who have significant injuries. Severe shortness of breath (the main symptom of ARDS) usually develops within a few hours to a few days after the primary injury or infection. It is the one of the main causes of death resulting from COVID-19 and many people who develop ARDS do not survive. The risk of death increases with age and severity of illness. People who survive ARDS may experience lasting damage to their lungs.

Bronchitis is an inflammation of the lining of the bronchial tubes of the lungs. Bronchitis may be either acute or chronic. While acute bronchitis is common, chronic bronchitis, a more serious condition, is a constant irritation or inflammation of the lining of the bronchial tubes.

Rheumatoid Arthritis

Rheumatoid arthritis is a chronic inflammatory disorder that can affect joints, skin, eyes, lungs, heart and blood vessels. As an autoimmune disorder, rheumatoid arthritis is caused by attacks to body tissues by one’s immune system. Unlike the wear-and-tear damage caused by osteoarthritis, rheumatoid arthritis causes a painful swelling that can eventually result in bone erosion and joint deformity.

HCQ is approved for treatment of rheumatoid arthritis in the form of hydroxychloroquine sulphate and marketed as Plaquenil. HCQ has risks of ocular toxicity and cardiac effects including cardiomyopathy and QT prolongation amongst long term users, as listed in the prescribing material.

Similarly, long term use of HCQ in rheumatoid arthritis patients was associated with increased cardiovascular mortality. Therefore, there is value in reducing the dose of HCQ in these arthritis patients. To understand the capacity for the combination of CBD with HCQ to permit reduction of the HCQ dose, in an animal study, low dose IHL-675A (1 mg/kg CBD + 2.5 mg/kg HCQ) was compared to a standard dose of HCQ (25 mg/kg HCQ). The 25 mg/kg HCQ dose in rats is equivalent to a 243 mg HCQ dose in a 60 kg human based on the FDA body surface area dose equivalence of 6/37.

In an animal study, low dose IHL-675A was more effective at reducing arthritis across multiple assessments including clinical score, paw volume, pannus score, total histology score and serum cytokine levels than the standard dose of HCQ. The reduction in disease assessments by low dose IHL-675A was 1.06-3.52 times that observed for HCQ alone at the standard dose.

This indicates that the combination of CBD and HCQ in IHL-675A has the potential to permit a ten-fold reduction in HCQ dose, when combined with CBD, without sacrificing efficacy in treatment of arthritis.

We have broadened claims within initial patent filings to cover rheumatoid arthritis as an indication. We are continuously monitoring the results of our research and development program, with a view to identifying and protecting new IP that aligns with our commercial objectives.

Inflammatory Bowel Disease

Inflammatory Bowel Disease (“IBD”) is an umbrella term used to describe disorders that involve chronic inflammation of the digestive tract. Significant types of IBD include:

•        Ulcerative colitis.    This condition involves inflammation and sores (ulcers) along the superficial lining of the large intestine (colon) and rectum.

•        Crohn’s disease.    This type of IBD is characterized by inflammation of the lining of the digestive tract, which often can involve the deeper layers of the digestive tract.

Both ulcerative colitis and Crohn’s disease are usually characterized by diarrhea, rectal bleeding, abdominal pain, fatigue and weight loss. IBD can be debilitating and sometimes leads to life-threatening complications.

The precise cause of inflammatory bowel disease remains unknown. Previously, diet and stress were suspected. However, currently medical practitioners acknowledge that these factors may aggravate, but are not the cause, of IBD. One possible cause is an immune system malfunction. When the immune system attempts to defeat an invading virus or bacterium, an abnormal immune response can cause the immune system to attack the cells in the digestive tract.

Preclinical in vitro study of IHL-675A against lung inflammation

On November 5, 2020, we released the results of our first in vitro study to investigate the synergistic activity of IHL-675A to inhibit inflammation. To test the anti-inflammatory potential of IHL-675A, human peripheral blood mononuclear cells (“PBMCs”) were stimulated with bacterial lipopolysaccharide (“LPS”). PBMCs were incubated with a range of concentrations of CBD and HCQ in combination or each drug alone and then stimulated with LPS to induce an inflammatory response. The inflammatory response was assessed by measuring cytokine levels in the culture medium after 24 hours. A reduction in cytokine levels in response to drug treatment is indicative of anti-inflammatory activity.

Cytokine levels were averaged across three replicates from two donors and normalized to maximum values to yield a relative inhibition value. A relative inhibition of 1 is complete inhibition of cytokine release whereas a value of 0 is no inhibition of cytokine release. Anti-inflammatory synergy was determined using the standard scientific “Excess over Bliss” (“EOB”) method where the predicted inhibition, as calculated using the formula Epred A+B=(EA+EB)-(EAEB), is subtracted from the observed inhibition to yield an EOB score. An EOB score of greater than zero indicates that the combination is synergistic.

The study demonstrated that CBD and HCQ act synergistically to inhibit production of the assessed inflammatory cytokines IL-1β, IL-6, TNF-α, IL-1aα, and MIP-1α by PBMCs from the donors. The average EOB scores ranged from 0.32-0.57. IHL-675A outperformed HCQ alone by 436% to 1320% and CBD alone by 109% to 767% across the five cytokines and outperformed the predicted cytokine inhibition of IHL-675A based on the activity of each drug alone by 87% to 767% across the 5 cytokines. The results in Figures A, B, C, D and E presented below, display the optimal fixed dose IHL-675A combination assessed for each cytokine. The bars noted as Predicted CBD+HCQ represent what our expectation was before the study commenced. The observed results from the study exceeded these in each inflammatory cytokine analyzed.

Figure 4. Inhibition of LPS-induced cytokine release from human PBMCs by CBD and HCQ.    Data is presented is the average relative inhibition for the PBMC donors. Predicted inhibition by CBD+HCQ was calculated using the formula Epred A+B=(EA+EB)-(EAEB). Observed CBD+HCQ is the level of inhibition observed in the experiment. (A) IL-1b, (B) IL-1a, (C) IL-6, (D) MIP-1a, and (E) TNF-a. Error bars are standard error of the mean of the donors.

Preclinical in vivo study of IHL-675A against inflammation

In November of 2020, we announced the results of an in vivo study assessing IHL-675A in a mouse model of sepsis. To determine whether CBD and HCQ synergize in vivo, mice from 11 groups of 10 mice, weighing 18-20g were injected with CBD and HCQ both alone and in combination. After one hour, the mice were injected with LPS to induce an inflammatory response. Each mouse in every cohort was assessed for each of the 5 inflammatory cytokines. Two hours after LPS injection, blood was collected from the mice by cardiac puncture. Sera were processed and analyzed for cytokine levels using a Luminex based assay. For synergy analysis, data was baseline subtracted using sham treated (no LPS injection) cytokine levels and then the values for each cytokine were normalized relative to maximum values across the groups. The normalized values were used to calculate the relative inhibition where a value of 1 is complete inhibition and a value of 0 is no inhibition. Synergy was calculated using the EOB method, or the difference between the observed and predicted inhibition between the combination of drug concentrations where the predicted inhibition is determined using the equation Epred A+B=(EA+EB)-(EAEB). An EOB score of greater than 0 is indicative of synergy.

The results of the in vivo study are presented in Figure 5, showing the optimal fixed dose IHL-675A combination assessed for each cytokine in 11 groups of 10 mice. The bars noted as ‘Predicted CBD + HCQ’ represent IHL’s expectation based on the activity of each drug alone. The observed results from the study significantly exceeded the predicted results across the inflammatory cytokines analyzed. CBD and HCQ synergize to inhibit the production of inflammatory cytokines IL-1β, IL-6, TNF- α, IL12(p70), and IFN- γ in a mouse model of LPS induced sepsis. The average EOB scores ranged from 0.15-0.30. IHL-675A outperformed CBD alone significantly across the five inflammatory cytokines. IHL-675A outperformed the predicted cytokine inhibition based on the activity of each drug alone by 26% to 81% across the five analyzed cytokines after 2 hours.

Figure 5. Synergistic anti-inflammatory activity of CBD and HCQ in a mouse sepsis model.    The anti-inflammatory activity of the combination of CBD and HCQ was greater than that predicted using the Excess over Bliss method. The CBD+HCQ combination was synergistic at inhibiting release of IL-1β, IL-6, TNF-α, IL12(p70), and IFN- γ.

Preclinical in vivo study of IHL-675A against Pulmonary Inflammation (ARDS, COPD, Asthma and Bronchitis)

In February 2021, we announced the results of an in vivo study assessing IHL-675A anti-inflammatory capabilities regarding chronic obstructive pulmonary disease, asthma, bronchitis, and other inflammatory respiratory conditions. We also assessed the anti-inflammatory effect of our proprietary IHL-675A’s formulation on Pulmonary Neutrophilia, which is a primary underlying cause of COPD, asthma, bronchitis, and other inflammatory respiratory conditions. We reported encouraging results, as discussed below, which facilitate a substantial expansion of the potential uses for IHL-675A and represent new patient treatment opportunities.

In July 2020, we conducted an animal study using rodents to assess the anti-inflammation efficacy of IHL-675A. In this study, ten groups of six mice each were pre-treated with either CBD, HCQ or IHL-675A prior to intratracheal administration of bacterial lipopolysaccharide (“LPS”), which was then inhaled and acts as an inflammatory stimulus in the lungs. A sham group where LPS was not administered to the mice was also included as a control. The lungs were flushed with a saline solution 24 hours after LPS administration and bronchoalveolar lavage fluid (‘BALF’) was analyzed for cytokine levels using a Luminex based assay. Cytokines are proteins that mediate the inflammatory response and a reduction in cytokine levels is indicative of reduced inflammation. A white blood cell (‘WBC’) count was also performed on the BALF. When inflammation occurs in the lungs, WBCs are recruited as part of the inflammatory response. A reduction in WBC count is also indicative of reduced inflammation.

In February 2021, we announced the results from this animal study, where Cytokine levels were normalized to those detected in vehicle treated mice and then the relative inhibition was calculated. IHL-675A reduced levels of all assessed inflammatory cytokines IL-1β, IL-6, TNF-α, CXCL1 and MCP-1 to a greater extent than either CBD or HCQ alone. WBC counts were normalized using the same method used for cytokines and IHL-675A reduced WBC counts to a greater extent than CBD or HCQ alone. These results indicate that IHL-675A has superior anti-inflammatory activity compared to CBD and HCQ in a mouse pulmonary inflammation model, and therefore IHL-675A may be effective in the treatment of anti-inflammation in humans.

Figure 6. Reduction in cytokine levels and white blood cell count in BALF resulting from treatment with by IHL-675A, CBD or HCQ in a mouse model of pulmonary inflammation.    Mice were treated with CBD, HCQ or a combination of CBD and HCQ (IHL-675A) and then LPS was administered intratracheally. Twenty-four hours after LPS administration bronchioalveolar lavage fluid (BALF) was analyzed for cytokine levels and white blood cell count. The reduction in cytokine levels by IHL-675A was greater than that for either drug alone. Drug concentrations were 1 mg/kg CBD and 25 mg/kg HCQ for (A) IL-1β, (B) IL-6, (C) MCP1 and (E) TNF-α, 10 mg/kg CBD and 2.5 mg/kg HCQ for CXCL-1 and WBC (white blood cell count).

Preclinical study of IHL-675A in a model of Rheumatoid Arthritis

In March 2021, we announced the results of an in vivo study assessing IHL-675A’s anti-inflammatory capabilities regarding rheumatoid arthritis. Results indicate that a low dose of IHL-675A was 1.06 to 3.52 times more effective at reducing arthritis across multiple assessments including clinical score, paw volume, pannus score, total histology score and serum cytokine levels compared to a standard dose of HCQ only. HCQ is approved and widely used for the treatment of rheumatoid arthritis in the form of hydroxychloroquine sulphate, which is marketed as Plaquenil.

In this model of rheumatoid arthritis, female Lewis rats were challenged with porcine type-II collagen with Freund’s adjuvant on Day 1 (0.2 mg/0.2 mL/rat) by subcutaneous injection at the base of the tail to induce arthritis. A booster injection at 0.1 mg/0.1 mL/rat was injected on day 7. On day 16, rats were allocated into groups of six. There were ten groups of modelled rats and one sham injected group. CBD, HCQ or IHL-675A were injected intraperitoneally once per day from day 17 to 30 (total of 14 days). Drug doses were 1 and 10 mg/kg CBD and 2.5 and 25 mg/kg HCQ. The 10 mg/kg CBD and 25 mg/kg HCQ doses were selected as they are representative of standard doses in humans based on the FDA body surface area dose equivalence estimation for rats to humans of 6/37. For a 60 kg person, the 10 mg/kg CBD dose in rats is equivalent to 97 mg and the 25 mg/kg HCQ dose in rats is equivalent to 243 mg. The maintenance dose range recommended for rheumatoid arthritis in the Plaquenil prescribing information is 200-400 mg daily.

Disease was assessed by measuring hind paw volume with a plethysmometer and using a qualitative severity score system on days 1, 7 ,10, 14, 16, 18, 20, 22, 24, 26, 28 and 30. Post termination on day 30, blood was collected from all rats and analyzed for levels of the inflammatory cytokines IL-1β and IL-6 using commercially available ELISA kits. These two cytokines were selected as they are known to be involved in the pathophysiology of rheumatoid arthritis. Both hind paws were harvested, weighed and formalin-fixed for histopathology. Histopathological evaluation consisted of an evaluation of cartilage and bone destruction by pannus formation (an abnormal layer of fibrovascular or granulated tissue) and mononuclear cell infiltration in synovial joint tissues. A total histology score, which is a sum of the pannus formation and mononuclear cell infiltration scores, was also calculated. For all assessments, the score was sham subtracted and then the reduction relative to the vehicle group was calculated.

IHL-675A outperformed HCQ alone in the study (at equivalent doses) at reducing clinical score and paw volume at days 24 and 30, pannus formation, total histology score, IL-1β and IL-6 in the rat model of arthritis. The reduction in disease assessments by IHL-675A was 1.07-8.72 times that observed for HCQ alone at an equivalent dose, which indicates that IHL-675A has a benefit in a rat model of arthritis greater than that of HCQ alone and demonstrates that IHL-675A is a potential treatment for arthritis in humans.

Figure 7. Comparison of low dose IHL-675A and standard dose HCQ in reduction of disease assessments in a rat model of rheumatoid arthritis.    Groups of rats that had undergone collagen-induced arthritis modelling were treated with low dose IHL-675A (1 mg/kg CBD + 2.5 mg/kg HCQ) or standard dose HCQ (25 mg/kg HCQ). The reduction in arthritis disease severity in low dose IHL-675A treated rats was greater than for standard dose HCQ treated rats with respect to (A) clinical score at day 24, (B) paw volume at day 24, (C) pannus formation, (D) total histology score, (E) serum IL-1β levels and (F) serum IL-6 levels.

Preclinical studies of IHL-675A in models of inflammatory bowel disease

In February 2021, we announced the results of an in vivo study assessing IHL-675A’s anti-inflammatory capabilities regarding inflammatory bowel disease. IHL-675A demonstrated a reduction in the Colitis index of 46%, while CBD only and HCQ only treatment achieved a reduction of 25% and 27% respectively, demonstrating that IHL-675A has superior anti-inflammatory activity compared to CBD only and HCQ only, which indicates that IHL-675A is a potential treatment for inflammatory bowel disease in humans.

This study used eleven groups of six mice. Mice were treated with IHL-675A, CBD or HCQ for four consecutive days after administration of TNBS/ethanol to induce ulcerative colitis. A vehicle treated group and sham group were included in the study. Stool consistency was monitored over the course of the experiment. On Day 5 mice were sacrificed, blood collected for cytokine analysis and the colon removed for analysis.

Endpoint measurements include stool consistency score (an ordinal scale that measures stool consistency with a higher number indicative of looser stools) , colon weight, colon macroscopic damage score (an ordinal scale that combines adhesions, strictures, ulcers/inflammations and instances of wall thickening), colitis index (a composite scale from the histological examination of colon sections) and myeloperoxidase (an enzyme abundantly expressed in neutrophil granulocytes that contributes to inflammatory damage in IBD) levels in the colon tissue at day 5. The results from each of these endpoints were sham subtracted and the relative reduction was calculated.

IHL-675A outperformed both CBD only and HCQ only at reducing the colitis index, macroscopic damage score, stool consistency score, colon to body weight ratio and myeloperoxidase (MPO) levels. These results indicate that IHL-675A has a benefit in a mouse model of ulcerative colitis greater than that of CBD or HCQ alone, which indicates that IHL-675A is a potential treatment for inflammatory bowel disease in humans.

Figure 8. Reduction in colitis score assessments by CBD and HCQ (IHL-675A) in a mouse model of colitis.    Colitis was induced in mice by intracolonic installation of TNBS/ethanol and then treated with CBD, HCQ or CBD and HCQ (IHL-675A). After 4 days, mice were sacrifice and the colons extracted for macro and microscopic analysis. The reduction in colitis severity was greater in mice treated with IHL-675A than for either CBD or HCQ alone for (A) colitis index, (B) macroscopic damage score, (C) relative colon weight, (D) stool consistency and (E) MPO levels. Drug dose in all assessments was 1 mg/kg CBD and 2.5 mg/kg HCQ.

Planned phase 1 clinical trial for IHL-675A

We have designed a Phase 1 clinical trial in Australia to assess the safety and pharmacokinetics of IHL-675A in healthy volunteers, the results of which will form part of our FDA IND submissions across the indications of lung inflammation, rheumatoid arthritis and inflammatory bowel disease. The aims of this study are to demonstrate that there are no, or minimal, additional risks/side effects associated with the combination of CBD and HCQ compared to each drug alone and that the uptake and metabolism (pharmacokinetics) of the two drugs do not interfere with one another. A total of 36 subjects will participate in the trial, evenly divided across three arms. The three arms of 12 subjects each will receive one of IHL-675A, Epidiolex (CBD), or Plaquenil (HCQ). The safety and pharmacokinetic assessments will be identical across the three arms.

CBD and HCQ both have both been used historically as treatments for our targeted indications when used independently. However, as with any pharmaceuticals there are risks involved. Part of the strategy in the design of IHL-675A is that the combination of CBD with HCQ permits a reduction in HCQ, which reduces the known risks associated with cumulative HCQ dose, without sacrificing efficacy. The preclinical studies we have conducted

to-date support that a lower cumulative dose of HCQ, when combined with CBD, has the potential to be effective in treating IHL-675A’s targeted indications. Nonetheless, there is always potential for two drugs to interact and exacerbate minor concerns that exist when used alone or lead to new safety concerns. Demonstrating that a combination drug containing CBD and HCQ has a similar safety profile to the component drugs is an important step in the development program and is a requirement set out by regulatory agencies. This clinical trial will be performed in a Phase 1 unit with around the clock monitoring in the event that an adverse event needs to be managed. Safety assessments will include cardiac monitoring via ECG and blood biomarkers, serum liver enzyme levels, blood cell counts and biochemistry, monitoring of vital signs and mental health questionnaires. Due to the substantial evidence of synergy between HCQ and CBD required to produce a superior outcome on inflammatory markers, dosages of HCQ and CBD may be significantly lower than for treatment with the individual drugs and this will be further evaluated in clinical trials.

The other component of this study is monitoring the pharmacokinetics of the two active pharmaceutical ingredients (“API”) of IHL-675A, CBD and HCQ, and comparing them to their respective reference listed drugs Epidiolex and Plaquenil. Study participants will be dosed with either IHL-675A, Epidiolex or Plaquenil with equivalent amounts of the respective API. Blood samples will be drawn at predetermined intervals over a 72-hour period and analyzed for levels of CBD and HCQ as well as their major metabolites. For each molecule the maximum concentration (“Cmax”), time to maximum concentration (“Tmax ”) and total exposure (“AUC”) will be determined. The pharmacokinetic parameters for IHL-675A, Epidolex and Plaquenil will be compared to determine whether the APIs in IHL-675A are bioequivalent to the reference listed drugs. Bioequivalence is an important component of the FDA 505(b)2 approval pathway that IHL is targeting with IHL-675A.

Results from this study will form a component of future regulatory applications for IHL-675A and will also inform the design of Phase 2 efficacy and safety studies across indications.

Psilocybin-assisted Psychotherapy for General Anxiety Disorder (Psi-GAD)

Generalized Anxiety Disorder

Generalized Anxiety Disorder (GAD) is characterized by diffuse, excessive, uncontrollable anxiety that frequently occurs and is not restricted to any particular environmental circumstances. Symptoms are variable, including feelings of persistent and excessive worry, nervousness, restlessness, difficulty in concentrating fatigue, irregular sleeping patterns, muscle tension, irritability, and nausea.

Generalized anxiety disorder is a relatively common and serious psychiatric condition affecting around 4-6% of the population during their lifetime. GAD can severely affect quality of life and professional career prospects.

Existing treatments

International guidelines for GAD treatment recommend selective serotonin reuptake inhibitors (“SSRIs”), serotonin and noradrenaline reuptake inhibitors (“SNRIs”), and pregabalin as first-line options, with benzodiazepines such as diazepam as second-line options. GAD is also treated with psychotherapy alone or in combination with pharmacotherapies. However, these treatments show limited efficacy, with less than half of patients achieving remission following these treatments and substantial treatment side-effects and cost. In particular, the side effects associated with long term use of these pharmacotherapies include emotional numbness, reduced positivity, weight gain, sexual disfunctions, and suicidal thoughts. Due to the limitations of existing treatments, we believe there is significant unmet need for new therapies to improve quality of life outcomes for patient diagnosed with GAD.

Psilocybin as a treatment for generalized anxiety disorder

Psychedelic-assisted psychotherapy may provide rapid, significant, and lasting benefit in treating unipolar depression, depression and anxiety symptoms associated with a terminal illness, and substance misuse. Psilocybin is a psychoactive molecule that occurs naturally in several genera of mushrooms, which primarily acts on the serotonin receptor system, and can modulate states of consciousness, cognition, perception, and mood.

When combined with specialized forms of psychotherapeutic support, psilocybin can be both a safe and highly effective mental health treatment. Through the 1950s and 1960s, tens of thousands of individuals participated in psychedelic research. While methodologically limited by modern standards, the findings from many of these studies showed substantial improvements in anxiety, depression and addiction levels, and quality of life.

Following decades of socio-political obstruction to psychedelic treatments, an increasing number of clinical psychedelic trials are now being conducted at highly esteemed institutions around the world, including Imperial College London, John Hopkins University, University of California, and now Monash University, Melbourne, in partnership with us.

Over the past decade, the therapeutic potential of psilocybin in anxiety, depression and addiction has been demonstrated in various academic-sponsored studies. In these studies, psilocybin-assisted psychotherapy, provided a rapid reduction in anxiety and depression symptoms on the day of administration with generally maintained treatment effects at follow-up assessments many months later. These studies have shown psilocybin to be generally well-tolerated, with low toxicity and no serious adverse events reported.

We believe that the following four studies detailed below support psilocybin-assisted therapy for treating anxiety using treatment dosages up to 30mg/70kg:

•        New York University, Ross et al 2016 (n=29): Rapid and sustained symptom reduction following psilocybin treatment for anxiety and depression in patients with life-threatening cancer: a randomized controlled trial. Psilocybin produced immediate, substantial, and sustained improvements in anxiety and depression, as well as decreases in cancer-related demoralization and hopelessness, improved spiritual wellbeing, and increased quality of life.

•        Imperial College London, Carhart-Harris et al 2018 (n=20): Psilocybin with psychological support for treatment-resistant depression: six-month follow-up. Good tolerability, effect sizes large and symptom improvements appeared rapidly after just two psilocybin treatment sessions and remained significant six months post-treatment in a treatment-resistant cohort.

•        University of California, Los Angeles, Grob et al 2011 (n=12): Pilot study of psilocybin treatment for anxiety in patients with advanced-stage cancer. The State-Trait Anxiety Inventory trait anxiety subscale demonstrated a significant reduction in anxiety at one and three months after treatment. There were no clinically significant adverse events with psilocybin.

•        John Hopkins University, Griffiths et al 2017 (n=51): Psilocybin produces substantial and sustained decreases in depression and anxiety in patients with life-threatening cancer: a randomized double-blind trial. Large and significant decreases in clinician-rated and self-rated measures of depression, anxiety or mood disturbance, and increase measures of quality of life, life meaning, death acceptance, and optimism.

Two psilocybin research programs for depression have received breakthrough designation from the FDA. A small number of other psilocybin treatment development programs are underway globally. Should the results from any of these research programs be positive, approval of psilocybin-assisted psychotherapy as a prescription treatment could occur within the next five years.

Our investigational psilocybin therapy for Generalized Anxiety Disorder

Our psilocybin therapy combines psilocybin with psychological therapy that has been specifically designed for patients diagnosed with generalized anxiety disorder by a multidisciplinary team of experts lead by Principal Investigator Dr Paul Liknaitzky, along with Co-Investigators Professor Suresh Sundram and Professor Murat Yucel. The wider research team includes experts in psychedelic-assisted therapies, psychometric evaluation, qualitative research, therapist training, and risk management. We are in the process of coordinating two clinical trials as part of our clinical development program, which we hope will lead to a Pre-IND submission in Q3 of 2021, and which is ultimately aimed at FDA approval of our psilocybin therapy administered to patients with GAD.

Planned Phase 2 exploratory clinical trial

The protocol for our planned Phase 2 Australian exploratory clinical trial has been completed and we anticipate submitting our research proposal to the human research ethics committee (“HREC”) for approval in Q3 of 2021. HREC approval is required prior to the commencement of patient recruitment in Australia. Dr Paul Liknaitzky has successfully achieved HREC approval for other clinical psilocybin studies in Australia and has successfully acquired regulatory permits and imported psilocybin into Australia.

The study is a Phase 2 randomized triple-blind active-placebo-controlled trial to assess the safety and efficacy of psilocybin-assisted psychotherapy for GAD. It will include 72 participants that will experience two psilocybin or active-placebo dosing sessions and up to 11 non-drug, specialist psychotherapy sessions over a period of 10 weeks. Primary outcomes are safety, efficacy and tolerability, and secondary outcomes are quality of life, functional impairment, and comorbidities.

A preliminary analysis of patient data will be conducted by an independent data safety monitoring board after 30 patients have completed primary endpoint assessment. The preliminary analysis will allow the trial investigators to inform the second part of the trial, with an opportunity to adjust certain treatment design parameters to optimize patient outcomes, or terminate the trial based on predefined outcomes and adequate conditional power.

FDA development plan and pre-IND meeting

In February 2021, we formally engaged Camargo Pharmaceuticals LLC, to advise upon and compile the pre-investigational new drug application information package necessary to formally request a pre-IND meeting with FDA. This meeting request will be submitted to the FDA in Q3 2021 and we anticipate that the meeting will occur in Q4 2021. We believe that FDA guidance will provide us with the regulatory clarity and commercial confidence to eventually submit an IND to the FDA and concurrently conduct a Phase 2b pivotal clinical trial partly or wholly in the United States in support of our IND submission.

Psilocybin therapy protocol

Our psilocybin therapy comprises administration of medication with psychotherapy by mental health professionals that have undergone our specialised therapist training program. Therapy is designed to optimize patient safety and therapeutic outcomes in GAD with specific support before, during and after psilocybin dosing sessions.

Each participant will receive two therapeutic doses of our investigational product, which will be composed of a specified dosage of psilocybin, with psychotherapy before, during and after each dose session. The psychotherapy comprises four distinct phases:

•        Preliminary psychotherapy: conducted during the screening stage with key focus on clinical formulation, therapeutic alliance, psychedelic treatment psychoeducation and practical preparation for dosing.

•        Preparation psychotherapy: conducted following full enrollment and prior to the first dosing session with a key focus on extending preliminary psychotherapy work, and covering more targeted and GAD-specific psychological and practical preparation for dosing.

•        After dosing support: conducted within a week following the preparation session with key focus on trust, suitable mindset, conducive physical setting, and participant-led support. Dosing support is the psychotherapy session.

•        Integration psychotherapy: conducted following the dosing sessions, including the day directly following each dosing session, with key focus on sustaining benefits through specific mindful, emotion and somatic-focused therapy, meaning-centered support, and facilitating contextual changes that support outcomes.

Therapist recruitment in anticipation of the Phase 2 exploratory trial has commenced and therapist training is anticipated to commence in Q3 2021.

Monash University

In December 2020, we entered into a partnership agreement with Monash University (“Monash”) in Australia to conduct a psilocybin-assisted psychotherapy trial to treat GAD. Monash will sponsor our initial Phase 2 exploratory clinical trial, ensuring rigorous scientific independence and the highest standards in ethical and safe research. We are funding and supporting this investigator-initiated trial, and retain all intellectual property created by the trial. We are also investigating the commencement of other psychedelic medicine research projects that would offer an opportunity to address what we believe is an unmet need in patients diagnosed with other mental illnesses.

Monash is one of Australia’s leading universities and consistently ranks among the world’s top 100. Psychedelic treatment for our exploratory trials will be delivered within BrainPark, a state-of-the-art research platform at Monash’s Turner Institute for Brain and Mental Health and Biomedical Imaging Facility, that provides a highly conducive environment for psychedelic treatments in a research context. Both the School of Psychological Sciences within the Turner Institute for Brain and Mental Health, and the Department of Psychiatry within the School of Clinical Sciences, have combined forces to conduct psychedelic research and the team comprises leading researchers and clinicians in relevant fields of psychiatry, psychotherapy, and mental health treatment development.

Clinical trial investigators

The Principal Investigator is Dr Paul Liknaitzky, with Co-Investigators Professor Murat Yucel and Professor Suresh Sundram.

Dr. Liknaitzky is Head of the Clinical Psychedelic Research Lab within the Turner Institute and the Dept of Psychiatry, Monash. He is a Chief Principal Investigator and Research Fellow at Monash University, and has Adjunct or Honorary appointments at St Vincent’s Hospital, Macquarie University, Deakin University, and the University of Melbourne. He earned an Honours in Neuroscience and a PhD in Psychology from the University of Melbourne. His work examines mechanisms of mental illness and treatment development primarily within mood, anxiety and addiction research. Liknaitzky is an Investigator across a number of Australia’s first clinical psychedelic trials. He has been invited to deliver numerous academic, professional, and public talks on psychedelic-assisted psychotherapy, and has been interviewed on the topic for print media, radio, and podcasts. Liknaitzky leads Australia’s first clinical psychedelic lab, coordinates Australia’s first applied psychedelic therapist training program, and is establishing Australia’s largest psychedelic trial (Psi-GAD). His work is focused on developing a rigorous program of research in psychedelic medicine at Monash University that seeks to evaluate therapeutic effects, innovate on treatment design, mitigate known risks, explore potential drawbacks, and understand therapeutic mechanisms.

Professor Murat Yucel gained a PhD combined with specialist clinical training in Clinical Neuropsychology in 2001 at La Trobe University. He then worked across as numerous mental health research centres at the University of Melbourne and was promoted to professor in 2012. He now works within the Monash School of Psychological Sciences, where he heads the mental health and addiction research programs.

He has been investigating the molecular pathology of schizophrenia and related psychotic disorders using pharmacological, neurochemical and neuropathological approaches. These inter-related methods have been applied to parse components of the disorder such as treatment resistance and suicide to better understand their neurobiological substrates. He undertook his doctoral and post-doctoral studies at the Mental Health Research Institute in Melbourne before establishing his laboratory there and subsequently at the Florey Institute and concurrently establishing a clinical research laboratory undertaking clinical trial and biomarker research in psychotic disorders. He then transferred to and integrated his research program at Monash University and Monash Medical Centre.

Intellectual Property Strategy

We strategically protect our innovations with a harmonized IP strategy, combining patent protection with regulatory and market exclusivity. We are pursuing patent protection for aspects of our psilocybin therapy program. The patent position that will be available to us is unlikely to cover psilocybin alone as a clinical entity. However, we are pursuing a patent position in relation methods of treatment using psilocybin including combination therapies (e.g., formulations, actives plus psychotherapeutic modalities) and other therapeutic methods (e.g., specific dosage regimens).

Intellectual Property

We have implemented a patent filing strategy as we develop our products and therapies in conjunction with our medical advisory board. As of December 31, 2020, we own pending patent applications relating to our drug candidates IHL-42X, IHL-216A and IHL-675A.

In addition to pursing patent protection for all of our assets, we rely on unpatented trade secrets, know-how and other confidential information as well as proprietary technological innovation and expertise that are protected in part by confidentiality and invention assignment agreements with our employees, advisors and consultants.

Patent matters in biotechnology are highly uncertain and involve complex legal and factual questions. The availability and breadth of claims allowed in biotechnology and pharmaceutical patents cannot be predicted. Statutory differences in patentable subject matter may limit the scope of protection we can obtain on some or all of our licensed inventions or prevent us from obtaining patent protection either of which could harm our business, financial condition and results of operations. Since patent applications are not published until at least 18 months from their first filing date and the publication of discoveries in the scientific literature often lags behind actual discoveries, we cannot be certain that we, or any of our licensors, were the first creator of inventions covered by pending patent applications, or that we or our licensors, were the first to file patent applications for such inventions. Additionally, the grant and enforceability of a patent is dependent on a number of factors that may vary between jurisdictions. These factors may include the novelty of the invention, the requirement that the invention not be obvious in the light of prior art (including prior use or publication of the invention), the utility of the invention and the extent to which the patent clearly describes the best method of working the invention. In short, this means that claims granted in various territories may vary and thereby influence commercial outcomes.

While we have applied for and will continue to file for protection as appropriate for our therapeutic products and technologies, we cannot be certain that any future patent applications we file, or licensed to us, will be granted, or that we will develop additional proprietary products or processes that are patentable or that we will be able to license any other patentable products or processes. We cannot be certain that others will not independently develop similar products or processes, duplicate any of the products or processes developed or being developed by the company or licensed to us, or design around the patents owned or licensed by us, or that any patents owned or licensed by us will provide us with competitive advantages.

Furthermore, we cannot be certain that patents held by third parties will not prevent the commercialization of products incorporating the technology developed by us or licensed to us, or that third parties will not challenge or seek to narrow, invalidate or circumvent any of the issued, pending or future patents owned or licensed by us.

Our commercial success will also depend, in part, on our ability to avoid infringement of patents issued to others. If a court determines that we were infringing any third-party patents, we could be required to pay damages, alter our products or processes, obtain licenses or cease certain activities. We cannot be certain that the licenses required under patents held by third parties would be made available on terms acceptable to us or at all. To the extent that we are unable to obtain such licenses, we could be foreclosed from the development, export, manufacture or commercialization of the product requiring such license or encounter delays in product introductions while we attempt to design around such patents, and any of these circumstances could have a material adverse effect on our business, financial condition and results of operations. We may have to resort to litigation to enforce any patents

issued or licensed to us or to determine the scope and validity of third-party proprietary rights. Such litigation could result in substantial costs and diversion of effort by us. We may have to participate in opposition proceedings before the Australian Patent and Trademark Office or another foreign patent office, or in interference proceedings declared by the United States Patent and Trademark Office, to determine the priority of invention for patent applications filed by competitors. Any such litigation interference or opposition proceeding, regardless of outcome, could be expensive and time consuming, and adverse determinations in any such proceedings could prevent us from developing, manufacturing or commercializing our products and could have a material adverse effect on our business, financial condition and results of operations.

As of June 30, 2021, the Company also owns trademark registrations in Australia, United States, Europe, China and Japan.

In fiscal year 2020, we added 5 new patent applications to our portfolio: PCT/AU2020/051056, Australian Provisional Patent Application No. 2020902368, Australian Provisional Patent Application No. 2020902432, Australian Provisional Patent Application No. 2020903985, and Australian Provisional Patent Application No. 2020904264.

Operations Summary

Unregistered Synthetic Cannabidiol Products

In February 2019, we launched a line of pharmaceutical grade cannabinoid oil products to treat conditions approved for treatment with cannabinoid under the Special Access Scheme. We sold our cannabinoid oil products under the Special Access Scheme. As of April 1, 2021, we ceased selling cannabinoid oil products to focus on the development of our drug candidates.

Patent Portfolio

The following table presents our portfolio of patents and patent applications, including their status (as at December 31, 2020) and title.

____________

*        Expiry date may be subject to any patent term extensions or adjustments that may be available.

Material Contracts

We are a clinical stage biotechnology company that has recently commenced its clinical trials and studies. Currently, we do not have any contract that would be deemed material that is not disclosed in other sections of this Registration Statement.

Quantitative and Qualitative Disclosures about Market Risk

Our cash consist entirely of cash held in interest-bearing accounts with banks in Australia. Thus, our primary exposure to market risk is interest income sensitivity, which is affected by changes in the general level of Australian interest rates. However, a sudden change in market interest rates would not be expected to have a material impact on our financial condition and/or results of operation.

Competition

We are targeting indications that have no registered, limited or costly pharmacological solutions. Thus, competitor drugs for the indications we are assessing with our drug candidates either do not exist or are limited in efficacy or have unacceptable side effect profiles for certain cohorts of patients. The table below outlines existing drugs and therapies used to treat the illnesses we aim to treat with our drug candidates and their associated pitfalls for patients.

Regulatory Authorities

The ongoing research and development, clinical, regulatory, commercial and manufacturing activities of our drug candidates are subject to extensive regulation by numerous governmental authorities, including (i) in Australia, principally the Therapeutics Goods Administration, or TGA; (ii) in the United States, principally the Food and Drug Administration, or FDA, as well as the Drug Enforcement Agency (DEA); and (iii) in Europe, principally the European Medicines Agency, or EMA and local competent authorities, ethics committees (ECs), institutional research boards (IRBs) and other regulatory authorities at federal, state or local levels. We, along with our third-party contractors, will be required to navigate the various preclinical, clinical and commercial approval and post-approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval or licensure of our drug candidates.

United States

FDA process

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or the FDCA, and its implementing regulations. Regulations that govern the pharmaceutical quality, safety, efficacy, labeling, storage, record keeping, advertising and promotion of such products under the Federal Food, Drug and Cosmetic Act, the Public Health Service Act, and their implementing regulations. In particular, controlled substances, like synthetic cannabidiol and THC, are regulated by the U.S. Drug Enforcement Administration, or DEA.

The process of obtaining FDA approval and achieving and maintaining compliance with applicable laws and regulations requires the expenditure of substantial time and financial resources. Failure to comply with applicable FDA or other requirements may result in refusal to approve pending applications, a clinical hold, warning letters, civil or criminal penalties, recall or seizure of products, partial or total suspension of production or withdrawal of the product from the market. FDA approval is required before any new drug or biologic, including a new use of a previously approved drug, can be marketed in the United States. All applications for FDA approval must contain, among other things, information relating to safety and efficacy, pharmaceutical quality, packaging, labeling and quality control.

Government oversight of the pharmaceutical industry is usually classified into pre-approval and post-approval categories. Most of the therapeutically significant innovative products marketed today are the subject of New Drug Applications, or NDAs, or Biologics License Applications, or BLAs. Pre-approval activities are used to assure the product is safe and effective before marketing.

Drug Approval Process — FDA

None of our drug candidates may be marketed in the United States until the drug has received FDA approval. The steps required before a drug may be marketed in the United States generally include the following:

•        completion of extensive pre-clinical laboratory tests, animal studies, and formulation studies in accordance with the FDA’s GLP and GMP regulations;

•        submission to the FDA of an Investigational New Drug, or IND, application for human clinical testing, which must become effective before human clinical trials may begin;

•        receive approval from the DEA prior to commencement of any clinical trials in the United States that involve the use of Schedule I controlled substances.

•        performance of adequate and well-controlled human clinical trials in accordance with GCP requirements to establish the safety and efficacy of the drug for each proposed indication;

•        submission to the FDA of an NDA/BLA after completion of all pivotal clinical trials;

•        satisfactory completion of an FDA pre-approval inspection of the manufacturing facility or facilities at which the active pharmaceutical ingredient, or API, and finished drug product are produced and tested to assess compliance with current Good Manufacturing Practices, or cGMPs; and

•        FDA review and approval of the NDA/BLA and DEA scheduling (for a controlled substance) prior to any commercial marketing or sale of the drug in the United States.

The manufacturing and quality, as well as preclinical and clinical testing and approval process requires substantial time, effort and financial resources, and we cannot guarantee approval of our drug candidates will be granted on a timely basis, if at all. Notably, the FDA may reach different conclusions than we have after analyzing the same data, or there may difference of opinion amongst members of FDA’s review team.

The FDA may inspect and audit domestic and foreign development facilities, planned production facilities, clinical trial sites and laboratory facilities. There is a pre-approval inspection after submission to market a new product, routine inspection of a regulated facility and a “for-cause” inspection to investigate a specific problem that has come to FDA’s attention. After the product is approved and marketed, the FDA uses different mechanisms for

assuring that firms adhere to the terms and conditions of approval described in the application and that the product is manufactured in a consistent and controlled manner. This is done by periodic unannounced inspections of production and quality control facilities by FDA’s field investigators and analysts.

Preclinical tests include laboratory evaluation of toxicity in animals and in vitro (laboratory tests). The results of preclinical tests, together with manufacturing information and analytical data, are submitted as part of an IND application to the FDA. The IND application is based on the results of initial testing done on animals for pharmacology and toxicity, which is used to develop a plan for testing the drug on humans. Only after preclinical testing, FDA determines whether the drug should be tested in people.

Further, an independent institutional review board, or IRB, covering each medical center proposing to conduct clinical trials must review and approve the plan for any clinical trial before it commences at that center and it must monitor the study until completed. The FDA, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk. Clinical testing also must satisfy extensive Good Clinical Practice, or GCP, regulations, which include requirements that all research subjects provide informed consent and that all clinical studies be conducted under the supervision of one or more qualified investigators.

Clinical trials (under an IND) involve administration of the investigational drug to human subjects under the supervision of qualified investigators. Clinical trials are conducted under protocols detailing the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. Each protocol must be provided to the FDA as part of a separate submission to the IND. Further, an Institutional Review Board, or IRB, for each medical center proposing to conduct the clinical trial must review and approve the study protocol and informed consent information for study subjects for any clinical trial before it commences at that center, and the IRB must monitor the study until it is completed. There are also requirements governing reporting of ongoing clinical trials and clinical trial results to public registries. Study subjects must sign an informed consent form before participating in a clinical trial.

Progress reports detailing the results of the clinical studies must be submitted at least annually to the FDA and safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse reactions in case of an open IND. For purposes of an NDA or BLA submission and approval, human clinical trials are typically conducted in the following sequential phases, which may overlap:

•        Phase I:    Trials are initially conducted in a limited population of healthy human (in oncology Phase I trials are often conducted in patients) subjects or patients to test the drug candidate for safety and dose tolerance. These studies are designed to test the safety, dosage tolerance, absorption, metabolism and distribution of the investigational product in humans, the side effects associated with increasing doses, and, if possible, to gain early evidence on effectiveness.

•        Phase II:    The investigational product is administered to a limited patient population with a specified disease or condition to evaluate the preliminary efficacy, optimal dosages and dosing schedule and to identify possible adverse side effects and safety risks. Multiple Phase 2 clinical trials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.

•        Phase III:    The investigational product is administered to an expanded patient population in adequate and well-controlled studies to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical trial sites. These clinical trials are intended to establish the overall risk/benefit relationship of the investigational product and to provide an adequate basis for product approval.

•        Phase IV:    In some cases, the FDA may condition approval of an NDA or BLA on the sponsor’s agreement to conduct additional clinical trials to further assess the drug candidate’s safety, purity and potency after NDA or BLA approval. Such post-approval trials are typically referred to as Phase IV clinical trials.

Concurrent with clinical studies, sponsors usually complete additional animal studies and must also develop additional information about the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the drug candidate and, among other things, the manufacturer must develop and

validate methods for testing the identity, strength, quality and purity of the final product. Moreover, appropriate packaging must be selected and tested and stability studies must be conducted to assure product integrity and demonstrate that the drug candidate does not undergo unacceptable deterioration over its shelf life.

The results of product development, preclinical studies and clinical trials, along with the aforementioned manufacturing information, are submitted to the FDA as part of a BLA/NDA. Under the Prescription Drug User Fee Act, or PDUFA, the FDA agrees to specific goals for NDA/BLA review time. The testing and approval process requires substantial time, effort and financial resources. The FDA will review the BLA/NDA and may deem it to be inadequate to support approval, and we cannot be sure that any approval will be granted on a timely basis, if at all. The FDA may also refer the application to the appropriate advisory committee, typically a panel of clinicians, for review, evaluation and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendations of the advisory committee, but it typically follows such recommendations.

The FDA may deny approval of a BLA/NDA if the applicable regulatory criteria are not satisfied, or it may require additional clinical data or additional pivotal Phase III clinical trials. Even if such data are submitted, the FDA may ultimately decide that the NDA/BLA does not satisfy the criteria for approval. Data from clinical trials are not always conclusive and the FDA may interpret data differently than the sponsor does. Once issued, product approval may be withdrawn by the FDA if ongoing regulatory requirements are not met or if safety problems occur after the product reaches the market. In addition, the FDA may require testing, including Phase IV clinical trials, and surveillance programs to monitor the effect of approved products that have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs which may include pediatric assessment, and potentially studies required for an application for a new indication, new dosage form, a new dosing regimen, a new route of administration or a new active ingredient. Products may be marketed only for the approved indications and in accordance with the provisions of the approved label. Further, if there are any modifications to the drug, including changes in indications, labeling or manufacturing processes or facilities, approval of a new or supplemental BLA may be required, which may involve conducting additional preclinical studies and clinical trials.

Expedited Review and Approval

The FDA has various programs, including fast track designation, priority review, accelerated approval, and breakthrough therapy designation, which are intended to expedite or simplify the process for reviewing drugs and/or provide for approval on the basis of surrogate endpoints. Even if a drug qualifies for one or more of these programs, the FDA may later decide that the drug no longer meets the conditions for qualification or that the time period for FDA review or approval will not be shortened. In particular, if accelerated approval is granted for any particular clinical product, the FDA can subsequently revoke the marketing authorization for such product if post-market clinical trial results are unsuccessful. Generally, drugs that may be eligible for these programs are those for serious or life-threatening diseases or conditions, those with the potential to address unmet medical needs, and those that offer meaningful benefits over existing treatments.

Other U.S. Regulatory Requirements

After approval, products are subject to extensive continuing regulation by the FDA, which include company obligations to manufacture products in accordance with GMP, maintain and provide to the FDA updated safety and efficacy information, report adverse experiences with the product, keep certain records and submit periodic reports, obtain FDA approval of certain manufacturing or labelling changes and comply with FDA promotion and advertising requirements and restrictions. Failure to meet these obligations can result in various adverse consequences, both voluntary and FDA-imposed, including product recalls, withdrawal of approval, restrictions on marketing, and the imposition of civil fines and criminal penalties against the BLA holder — all of which may become public. In addition, later discovery of previously unknown safety or efficacy issues may result in restrictions on the product, manufacturer or application holder.

We, and any manufacturers of our drug candidates, are required to comply with applicable FDA manufacturing requirements contained in the FDA’s GMP regulations. GMP regulations require, among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation. The manufacturing

facilities for our drug candidates must meet GMP requirements. We, and any third-party manufacturers, are also subject to periodic inspections of facilities by the FDA and other authorities, including procedures and operations used in the testing and manufacture of our drug candidates to assess our compliance with applicable regulations.

With respect to post-market product advertising and promotion, the FDA imposes a number of complex regulations on entities that advertise and promote pharmaceuticals, which include, among others, standards for direct-to-consumer advertising, promoting products for uses or in patient populations that are not described in the product’s approved labelling (known as “off-label use”), industry-sponsored scientific and educational activities, and promotional activities involving the Internet. Failure to comply with FDA requirements can have negative consequences, including adverse publicity, enforcement letters from the FDA, mandated corrective advertising or communications with doctors and civil or criminal penalties. Although physicians may prescribe legally available drugs for off-label uses, manufacturers may not market or promote such off-label uses.

Changes to some of the conditions established in an approved application, including changes in indications, labelling, or manufacturing processes or facilities, require submission and FDA approval of a new BLA or BLA supplement before the change can be implemented. A BLA supplement for a new indication typically requires clinical data similar to that in the original application, and the FDA uses the same procedures and actions in reviewing BLA supplements as it does in reviewing BLAs.

Adverse event reporting and submission of periodic reports is required following FDA approval of a BLA. The FDA also may require post-marketing testing, known as Phase IV testing, risk mitigation strategies, and surveillance to monitor the effects of an approved product or place conditions on an approval that could restrict the distribution or use of the product.

Controlled Substances

The CSA and its implementing regulations establish a “closed system” of distribution for controlled substances. The CSA imposes registration, security, recordkeeping and reporting, storage, manufacturing, distribution, labeling, importation, exportation, disposal and other requirements under the oversight of the DEA. The DEA is the federal agency responsible for regulating controlled substances, and requires those individuals or entities that manufacture, import, export, distribute, research, or dispense controlled substances to comply with the regulatory requirements to prevent the diversion of controlled substances to illicit channels of commerce.

Facilities that research, manufacture, distribute, import or export any controlled substance must register annually with the DEA. The DEA registration is specific to the particular location, activity(ies) and controlled substances utilized. For example, separate registrations are required for importation and manufacturing activities, and each registration authorizes which schedules of controlled substances the registrant may handle. However, certain coincident activities are permitted without obtaining a separate DEA registration, such as distribution of controlled substances by the manufacturer that produces them.

The DEA categorizes controlled substances into one of five schedules — Schedule I, II, III, IV, or V — with varying qualifications for listing in each schedule. Scheduling determination by the DEA are dependent on approval of a substance or a specific formulation of a substance. Schedule I substances by definition have a high potential for abuse, have no currently “accepted medical use” in treatment in the United States and lack accepted safety for use under medical supervision. They may be used only in federally-approved research programs and may not be marketed or sold for dispensing to patients in the United States. Pharmaceutical products having a currently accepted medical use may be listed as Schedule II, III, IV or V substances, with Schedule II substances presenting the highest potential for abuse and physical or psychological dependence, and Schedule V substances presenting the lowest relative potential for abuse and dependence. The regulatory requirements are more restrictive for Schedule II substances than Schedule III-V substances. For example, all Schedule II drug prescriptions must be signed by a physician, physically presented to a pharmacist in most situations, and cannot be refilled. Marijuana and THC are Schedule I controlled substances under the CSA. Products approved for medical use in the United States that contain marijuana, THC or marijuana/THC extracts, must be placed in Schedules II-V, since approval by the FDA satisfies the “acceptable medical use” requirement. While marijuana and THC are controlled substances, the Agricultural Improvement Act of 2018 amended the CSA to exclude Cannabis meeting the statutory definition of hemp from the definition of marijuana. As a result, Cannabis that contains 0.3 percent or less of delta-9 THC on a dry weight basis is no longer considered a controlled substance. By extension, Cannabis-derived cannabidiol that satisfies the same limitation concerning delta-9 THC is also excluded from CSA regulatory controls. Because the definition of hemp

does not expressly include synthetic equivalents of Cannabis or its derivatives, however, there is a lack of clarity about the CSA control status of pharmaceutically manufactured cannabidiol. Absent guidance to the contrary from the DEA, Cannabis and those products which contain Cannabis, that do not meet the definition of hemp remain in Schedule I of the CSA for purposes of development and research activities.

The DEA inspects all manufacturing facilities to review security, record keeping, reporting and compliance with other DEA regulatory requirements prior to issuing a controlled substance registration. The specific security requirements vary by the type of business activity and the schedule and quantity of controlled substances handled. The most stringent requirements apply to manufacturers of Schedule I and Schedule II substances. Required security measures commonly include background checks on employees and physical control of controlled substances through storage in approved vaults, safes and cages, and through use of alarm systems and surveillance cameras. An application for a manufacturing registration as a bulk manufacturer (not a dosage form manufacturer or a repacker/relabeler) for a Schedule I or II substance must be published in the Federal Register and is open for 30 days to permit interested persons to submit comments, objections, or requests for a hearing. A copy of the notice of the Federal Register publication is forwarded by the DEA to all those registered, or applicants for registration, as bulk manufacturers of that substance. Once registered, manufacturing facilities must maintain records documenting the manufacture, receipt and distribution of all controlled substances. Manufacturers must submit periodic reports to the DEA of the distribution of Schedule I and II controlled substances, Schedule III narcotic substances, and other designated substances. Registrants must also report any controlled substance thefts or significant losses and must adhere to certain requirements to dispose of controlled substances. As with applications for registration as a bulk manufacturer, an application for an importer registration for a Schedule I or II substance must also be published in the Federal Register, which remains open for 30 days for comments. Imports of Schedule I and II controlled substances for commercial purposes are generally restricted to substances not already available from a domestic supplier or where there is not adequate competition among domestic suppliers. In addition to an importer or exporter registration, importers and exporters must obtain a permit for every import or export of a Schedule I and II substance, Schedule III, IV and V narcotic, specially designated Schedule III non-narcotics, or Schedule IV or V narcotic controlled in Schedule I or II by the Convention on Psychotropic Substances and submit import or export declarations for Schedule III, IV and V non-narcotics.

For drugs manufactured in the United States, the DEA establishes annually an aggregate quota for the amount of substances within Schedules I and II that may be manufactured or produced in the United States based on the DEA’s estimate of the quantity needed to meet legitimate medical, scientific, research and industrial needs. This limited aggregate amount of Cannabis that the DEA allows to be produced in the United States each year is allocated among individual companies, which, in turn, must annually apply to the DEA for individual manufacturing and procurement quotas. The quotas apply equally to the manufacturing of the active pharmaceutical ingredient and production of dosage forms. The DEA may adjust aggregate production quotas a few times per year, and individual manufacturing or procurement quotas from time to time during the year, although the DEA has substantial discretion in whether or not to make such adjustments for individual companies.

The states also maintain separate controlled substance laws and regulations, including licensing, recordkeeping, security, distribution, and dispensing requirements. State Authorities, including Boards of Pharmacy, regulate use of controlled substances in each state. Failure to maintain compliance with applicable requirements, particularly as manifested in the loss or diversion of controlled substances, can result in enforcement action that could have a material adverse effect on our business, operations and financial condition. The DEA may seek civil penalties, refuse to renew necessary registrations, or initiate proceedings to revoke those registrations. In certain circumstances, violations could lead to criminal prosecution.

We will not be subject to the DEA approval to conduct our clinical trials for the foreseeable future because we have conducted and plan to continue to conduct clinical trials for each clinical drug program in Australia. We may also decide to develop, manufacture or commercialize our drug candidates in additional countries. As a result, we will be subject to controlled substance laws and regulations from the TGA in Australia, Health Canada’s Office of Controlled Substances in Canada, the Drugs & Firearms Unit (Home Office) of the National Drug Control System in the United Kingdom, and from other regulatory agencies in other countries where we develop, manufacture or commercialize each drug asset in the future.

Foreign Regulation

In addition to regulations in the United States, we are subject to a variety of foreign regulations governing clinical trials and commercial sales and distribution of our drug candidates. Whether or not we obtain FDA approval for a product, we must obtain approval of a product by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country and the time may be longer or shorter than that required for FDA approval. The requirements governing the conduct of clinical trials vary greatly from country to country.

European Union and United Kingdom

In the European Economic Area, or EEA, which is comprised of the Member States of the European Union plus Norway, Iceland and Liechtenstein, medicinal products can only be commercialized after obtaining a Marketing Authorization, or MA by the EMA. Under European Union regulatory systems, we must submit and obtain authorization for a clinical trial application in each member state in which we intend to conduct a clinical trial. When conducting clinical trials in the European Union, we must adhere to the provisions of the European Union Clinical Trials Directive (Directive 2001/20/EC) and the laws and regulations of the EU Member States implementing them. These provisions require, among other things, that the prior authorization of an Ethics Committee and the competent Member State authority is obtained before commencing the clinical trial. In April 2014, the European Union passed the Clinical Trials Regulation (Regulation 536/2014), which will replace the current Clinical Trials Directive. To ensure that the rules for clinical trials are identical throughout the European Union, the EU Clinical Trials Regulation was passed as a regulation that is directly applicable in all EU member states. All clinical trials performed in the European Union are required to be conducted in accordance with the Clinical Trials Directive until the Clinical Trials Regulation becomes applicable. According to the current plans of the EMA, the Clinical Trials Regulation is expected to become applicable.

After we have completed our clinical trials, we must obtain marketing authorization before we can market our product. We may submit applications for marketing authorizations under a centralized procedure. The centralized procedure provides for the grant of a single marketing authorization that is valid for all European Union member states.

The European Medicines Agency, or EMA, is a body of the European Union located in Amsterdam. The EMA is responsible for the scientific evaluation of medicines developed by pharmaceutical companies for use in the European Union. The EMA is involved in the scientific evaluation of medicines that fall within the scope of the centralized procedure. Like the FDA there is a harmonization between regulators and the EMA may inspect and audit the development facilities, planned production facilities, clinical trial sites and laboratory facilities. Additionally, after the product is approved and marketed, the EMA uses different mechanisms for assuring that firms adhere to the terms and conditions of approval described in the application and that the product is manufactured in a consistent and controlled manner. This is done by periodic unannounced inspections of production and quality control facilities.

If any of our drug candidates receive marketing approval in the EEA, we expect they will benefit from 8 years of data protection and 10 years of market protection. The periods run in parallel so effectively 8 years of data protection plus 2 years of market protection is granted. This means that a biosimilar application referencing our safety and efficacy data held on file at the EMA cannot be filed until the end of the data protection period of 8 years, and the biosimilar cannot be placed on the market until after a further 2 years have elapsed (8 + 2). Furthermore, an additional 1 year of market protection is available (8 + 2 + 1) where we obtain approval of a second indication having a significant clinical benefit in the initial 8-year period.

Similarly, since the Biologics Price Competition and Innovation Act (BPCIA) came into force in 2010, the United States provides 4 years of data exclusivity and 12 years of marketing exclusivity for a new biologic. The periods of exclusivity run in parallel, meaning that the FDA will not accept a biosimilar filing for 4 years and will not approve the biosimilar for a further 8 years (4 + 8).

Regulation and Procedures Governing Approval of Medicinal Products in the European Union

In order to market any product outside of the United States, a company must also comply with numerous and varying regulatory requirements of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of products. Whether or not it obtains FDA approval for a product, an applicant will need to obtain the necessary approvals by the comparable foreign regulatory authorities before it can initiate clinical trials or marketing of the product in those countries or jurisdictions. Specifically, the process governing approval of medicinal products in the European Union generally follows the same lines as in the United States, although the approval of a medicinal product in the United States is no guarantee of approval of the same product in the European Union, either at all or within the same timescale as approval may be granted in the United States. It entails satisfactory completion of pharmaceutical development, non-clinical studies and adequate and well-controlled clinical trials to establish the safety and efficacy of the medicinal product for each proposed indication. It also requires the submission to relevant competent authorities for clinical trials authorization for a marketing authorization application, or MAA, and granting of a marketing authorization by these authorities before the product can be marketed and sold in the European Union or its member states (as well as Iceland, Norway and Liechtenstein). If we fail to comply with applicable requirements, we may be subject to, among other things, fines, suspension of clinical trials, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Clinical Trial Approval

Pursuant to the currently applicable Clinical Trials Directive 2001/20/EC and the Directive 2005/28/EC on GCP, a system for the approval of clinical trials in the European Union has been implemented through national legislation of the member states. Under this system, an applicant must obtain approval from the national competent authority, or NCA, of a European Union member state in which the clinical trial is to be conducted or in multiple member states if the clinical trial is to be conducted in a number of member states. Furthermore, the applicant may only start a clinical trial at a specific study site after the independent ethics committee, or EC, has issued a favorable opinion in relation to the clinical trial. The clinical trial application must be accompanied by an investigational medicinal product dossier with supporting information prescribed by Directive 2001/20/EC and Directive 2005/28/EC and corresponding national laws of the member states and further detailed in applicable guidance documents. Under the current regime all suspected unexpected serious adverse reactions to the investigated drug that occur during the clinical trial have to be reported to the NCA and ECs of the member state where they occurred.

In April 2014, the European Union adopted a new Clinical Trials Regulation (EU) No 536/2014, which is set to replace the current Clinical Trials Directive 2001/20/EC. It will overhaul the current system of approvals for clinical trials in the European Union. Specifically, the new legislation, which will be directly applicable in all EU member states (meaning that no national implementing legislation in each European Union member state is required), aims at simplifying and streamlining the approval of clinical trials in the European Union. For instance, the new Clinical Trials Regulation provides for a streamlined application procedure via a single-entry point and strictly defined deadlines for the assessment of clinical trial applications. It is expected that the new Clinical Trials Regulation will come into effect following confirmation of full functionality of the Clinical Trials Information System, the centralized EU portal and database for clinical trials foreseen by the new Clinical Trials Regulation, through an independent audit, which is currently expected to occur in December 2021.

Marketing Authorization

To obtain a marketing authorization for a product in the European Economic Area (comprised of the EU member states plus Norway, Iceland and Liechtenstein), or EEA, an applicant must submit a MAA, either under a centralized procedure administered by the EMA or one of the procedures administered by competent authorities in the EEA member states (decentralized procedure, national procedure, or mutual recognition procedure). A marketing authorization may be granted only to an applicant established in the EEA.

Controlled Drugs Classification

The position in the member states of the European Union is not harmonized. Member states have implemented the relevant UN Conventions (the Single Convention of Narcotic Drugs 1961 and the Convention on Psychotropic Substances 1971) into their national legislation, which has led to differences in how controlled substances are regulated in different countries of the European Union. It is therefore important to determine at a national level whether a substance is controlled and to comply with the applicable legal requirements.

Regulatory Requirements After Marketing Authorization

Following approval, the holder of the marketing authorization is required to comply with a range of requirements applicable to the manufacturing, marketing, promotion and sale of the medicinal product.

These include compliance with the European Union’s stringent pharmacovigilance or safety reporting rules, pursuant to which post-authorization studies and additional monitoring obligations can be imposed. The holder of a marketing authorization must establish and maintain a pharmacovigilance system and appoint an individual qualified person for pharmacovigilance, who is responsible for oversight of that system. Key obligations include expedited reporting of suspected serious adverse reactions and submission of periodic safety update reports, or PSURs.

In addition, all new MAAs must include a risk management plan, or RMP, describing the risk management system that the company will put in place and documenting measures to prevent or minimize the risks associated with the product. The regulatory authorities may also impose specific obligations as a condition of the marketing authorization. Such risk-minimization measures or post-authorization obligations may include additional safety monitoring, more frequent submission of PSURs, or the conduct of additional clinical trials or post-authorization safety studies. RMPs and PSURs are routinely available to third parties requesting access, subject to limited redactions.

Furthermore, the manufacturing of authorized products, for which a separate manufacturer’s license is mandatory, must also be conducted in strict compliance with the EMA’s cGMP requirements and comparable requirements of other regulatory bodies in the European Union, which mandate the methods, facilities and controls used in manufacturing, processing and packing of products to assure their safety and identity.

Finally, the marketing and promotion of authorized products, including industry-sponsored continuing medical education and advertising directed toward the prescribers of products, are strictly regulated in the European Union under Directive 2001/83/EC, as amended. The advertising of prescription-only medicines to the general public is not permitted in the European Union, or in the UK under the Human Medicines Regulations 2021. Although general requirements for advertising and promotion of medicinal products are established under EU Directive 2001/83/EC as amended, the details are governed by regulations in each European Union member state (as well as Iceland, Norway and Liechtenstein) and can differ from one country to another.

United Kingdom

The United Kingdom (UK) has left the European Union and will declare its independent processes to approve clinical research and marketing authorizations. Currently, the UK is in a transition period after it left the European Union, leaving EU regulations and agreements active. This transition period ended on December 31, 2020. Since the regulatory framework in the UK covering quality, safety and efficacy of pharmaceutical products, clinical trials, marketing authorization, commercial sales and distribution of pharmaceutical products is derived from EU Directives and Regulations, Brexit could materially impact the future regulatory regime which applies to products and the approval of drug candidates in the UK, as UK legislation now has the potential to diverge from EU legislation. It remains to be seen how Brexit will impact regulatory requirements for drug candidates and products in the UK in the long-term. The MHRA has recently published detailed guidance for industry and organizations to follow from January 1, 2021, which will be updated as the UK’s regulatory position on medicinal products evolves over time. How precisely clinical research within the UK will be performed and how approval for drugs will be organized is subject to ongoing discussions

The UK will no longer be covered by centralized marketing authorizations (under the Northern Irish Protocol, centralized marketing authorizations will continue to be recognized in Northern Ireland). All medicinal products with a current centralized marketing authorization were automatically converted to Great Britain marketing authorizations on January 1, 2021. For a period of two years from January 1, 2021, the MHRA may rely on a decision taken by the European Commission on the approval of a new marketing authorization in the centralized procedure, in order to more quickly grant a new Great Britain marketing authorization. A separate application will, however, still be required.

Australia

In Australia, the relevant regulatory body responsible for the pharmaceutical industry is the Therapeutics Goods Administration, or TGA. As with the EMA and FDA there is a harmonization and collaboration between regulatory authorities. The TGA requires notification of all clinical trials via an electronic submission of a Clinical Trial Notification (CTN) prior to commencing the clinical trial.

Third-Party Payer Coverage and Reimbursement

Although our drug candidates have not been commercialized for any indication, if they are approved for marketing, commercial success of our drug candidates will depend, in part, upon the availability of coverage and reimbursement from third party payers at the federal, state and private levels.

In the United States and internationally, sales of any product that we market in the future, and our ability to generate revenues on such sales, are dependent, in significant part, on the availability of adequate coverage and reimbursement from third party payors, such as state and federal governments, managed care providers and private insurance plans.

Private insurers, such as health maintenance organizations and managed care providers, have implemented cost-cutting and reimbursement initiatives and likely will continue to do so in the future. These include establishing formularies that govern the drugs and biologics that will be offered and the out-of-pocket obligations of member patients for such products. We may need to conduct pharmacoeconomic studies to demonstrate the cost-effectiveness of our drug candidates for formulary coverage and reimbursement. Even with such studies, our drug candidates may be considered less safe, less effective or less cost-effective than existing products, and third-party payors may not provide coverage and reimbursement for our drug candidates, in whole or in part. In addition, particularly in the United States and increasingly in other countries, we are required to provide discounts and pay rebates to state and federal governments and agencies in connection with purchases of our drug candidates that are reimbursed by such entities. It is possible that future legislation in the United States and other jurisdictions could be enacted to potentially impact reimbursement rates for the drug candidates we are developing and may develop in the future and could further impact the levels of discounts and rebates paid to federal and state government entities. Any legislation that impacts these areas could impact, in a significant way, our ability to generate revenues from sales of drug candidates that, if successfully developed, we bring to market. Political, economic and regulatory influences are subjecting the healthcare industry in the United States to fundamental changes. There have been, and we expect there will continue to be, legislative and regulatory proposals to change the healthcare system in ways that could significantly affect our future business.

Similar political, economic and regulatory developments are occurring in the European Union and may affect the ability of pharmaceutical companies to profitably commercialize their products. In addition to continuing pressure on prices and cost containment measures, legislative developments at the European Union or member state level may result in significant additional requirements or obstacles. The delivery of healthcare in the European Union, including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than European Union, law and policy. National governments and health service providers have different priorities and approaches to the delivery of health care and the pricing and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most EU member states have resulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. Coupled with ever-increasing EU and national regulatory burdens on those wishing to develop and market products, this could restrict or regulate post-approval activities and affect the ability of pharmaceutical companies to commercialize their products. In international markets, reimbursement and healthcare payment systems vary

significantly by country, and many countries have instituted price ceilings on specific products and therapies. In the future, there may continue to be additional proposals relating to the reform of the healthcare system in the United States and international healthcare systems. Future legislation, or regulatory actions implementing recent or future legislation may have a significant effect on our business. Our ability to successfully commercialize products depends in part on the extent to which reimbursement for the costs of our drug candidates and related treatments will be available in the United States and worldwide from government health administration authorities, private health insurers and other organizations. The adoption of certain proposals could limit the prices we are able to charge for our drug candidates, the amounts of reimbursement available for our drug candidates, and limit the acceptance and availability of our drug candidates. Therefore, substantial uncertainty exists as to the reimbursement status of newly approved health care products by third party payors.

Exchange Controls

Australia has largely abolished exchange controls on investment transactions. The Australian dollar is freely convertible into U.S. dollars. In addition, there are currently no specific rules or limitations regarding the export from Australia of profits, dividends, capital or similar funds belonging to foreign investors, except that certain payments to non-residents must be reported to the Australian Cash Transaction Reports Agency, which monitors such transaction, and amounts on account of potential Australian tax liabilities may be required to be withheld unless a relevant taxation treaty can be shown to apply.

The Foreign Acquisitions and Takeovers Act 1975

Under Australian law, in certain circumstances foreign persons are prohibited from acquiring more than a limited percentage of the shares in an Australian company without approval from the Australian Treasurer. These limitations are set forth in the Australian Foreign Acquisitions and Takeovers Act, or the Takeovers Act.

Under the Foreign Acquisitions and Takeovers Act, as currently in effect, any foreign person, together with associates, or parties acting in concert, is prohibited from acquiring 20% or more of the shares in any company having consolidated total assets of or that is valued at A$275 million or more (or A$1,192 million or more in case of U.S. investors). “Associates” is a broadly defined term under the Takeovers Act 1975 and includes the following, but not limited to:

•        any relative of the person;

•        any person with whom the person is acting or proposes to act in concert;

•        any person with whom the person carries on a business in partnership;

•        any entity of which the person is a ‘senior officer’ (such as a director or executive);

•        if the person is an entity, any holding entity or any senior officer of the entity;

•        any entity whose senior officers are accustomed or obliged to act in accordance with the directions, instructions or wishes of the person or if the person is an entity, its senior officers or vice versa;

•        any corporation in which the person holds a ‘substantial interest’ (i.e., 20%) or any person holding a substantial interest in the person if a corporation;

•        a trustee of a trust in which the person holds a substantial interest or if the person is the trustee of a trust, a person who holds a substantial interest in the trust; and

•        if the person is a foreign government, a separate government entity or a foreign government investor in relation to a foreign country, any other person that is a foreign government, a separate government entity or foreign government investor, in relation to that country.

The Australian Treasurer also has power in certain circumstances to make an order specifying that two or more persons are associates.

In addition, a foreign person may not acquire shares in a company having consolidated total asset of or that is valued at A$275 million or more (or A$1,192 million or more in case of U.S. investors) if, as a result of that acquisition, the total holdings of all foreign persons and their associates will exceed 40% in aggregate without the approval of the Australian Treasurer. If the necessary approvals are not obtained, the Treasurer may make an order requiring the acquirer to dispose of the shares it has acquired within a specified period of time. The same rule applies if the total holdings of all foreign persons and their associates already exceeds 40% and a foreign person (or its associate) acquires any further shares, including in the course of trading in the secondary market of the ADSs. At present, we do not have total assets of A$275 million or more. At this time, our total assets do not exceed any of the above thresholds and therefore no approval would be required from the Australian Treasurer. Nonetheless, if our total assets were to exceed the threshold in the future, we would be mindful of the number of ADS that can be made available, and monitor the 40% aggregate shareholding threshold for foreign persons (together with the associates) to ensure that it will not be exceeded subject to the Australian Treasurer’s approval.

Each foreign person seeking to acquire holdings in excess of the above caps (including their associates, as the case may be) would need to complete an application form setting out the proposal and relevant particulars of the acquisition/shareholding. The Australian Treasurer then has 30 days to consider the application and make a decision. However, the Australian Treasurer may extend the period by up to a further 90 days by publishing an interim order. The Australian Treasurer has issued a guideline titled Australia’s Foreign Investment Policy which provides an outline of the policy. As for the risk associated with seeking approval, the policy provides that the Treasurer will reject an application if it is contrary to the national interest.

If the level of foreign ownership exceeds 40% at any time, we would be considered a foreign person under the Foreign Acquisitions and Takeovers Act. In such event, we would be required to obtain the approval of the Australian Treasurer for our company, together with our associates, to acquire (i) more than 15% of an Australian company or business having total assets of or that is valued at A$275 million (or A$1,192 if the investor is a non-government entity from a ‘partner agreement’ country) or more; or (ii) any direct or indirect ownership in Australian residential real estate and certain non-residential real estate.

The percentage of foreign ownership in our company may also be included determining the foreign ownership of any Australian company or business in which we may choose to invest. Since we have no current plans for any such acquisition and do not own any property, any such approvals required to be obtained by us as a foreign person under the Takeovers Act will not affect our current or future ownership or lease of property in Australia.

Our Constitution does not contain any additional limitations on a non-resident’s right to hold or vote our securities.

Australian law requires the transfer of shares in our company to be made in writing or electronically through the Clearing House Electronic Sub-register System.

Inflation and Seasonality

Management believes inflation has not had a material impact on our operations or financial condition. Management further believes that our operations are not currently subject to seasonal influences due to our current lack of marketed products. Moreover, the targets of our drug candidates, are not seasonal diseases. Accordingly, once we have marketed products, management does not expect that our business will be subject to seasonal influences.

Manufacturing and Raw Materials

We have no manufacturing capabilities and are dependent on third parties for cost effective manufacture and manufacturing process development of our drug candidates. Problems with third party manufacturers or the manufacturing process as such may delay or jeopardize clinical trials and commercialization of our drug candidates.

History and Development

Our legal name is Incannex Healthcare Limited. We were incorporated in Australian in April 2001 under the name Mount Magnet South Limited. In November 2016, we changed name to Impression Healthcare Limited, and in June 2020, to Incannex Healthcare Limited. Incannex is listed on the ASX under the symbol “IHL.”

Since 2019, we have been conducting research and development for medicinal synthetic cannabidiol pharmaceutical products and psychedelic medicine therapies for treatment of a range of indications.

In June 2020, we discontinued the sale of mouthguards for sports activities to focus its resources on cannabinoid sales and development activities. As a result, on June 30, 2020, we sold our wholly-owned subsidiary Gameday International Pty Ltd. Sales of sports mouthguards had severely diminished due to the cancellation of sport seasons resulting from COVID- 19 restrictions. We did not expect any normal continuation of the sports season or recovery in mouthguard sales in the medium term that justifies continued financial commitment.

In January 2019, the Department of Health of Victoria granted us licenses to sell or supply cannabinoid substances, and in particular cannabis, cannabidiol (“CBD”), tetrahydrocannabinols (“THC”) and dronabinol.

Our registered office is located at Suite 15, Level 12, 401 Docklands Drive, Docklands 3008, Victoria, Australia and our telephone number is +61 409 840 786. Our agent for service of process in the United States is Vcorp Agent Services, Inc., 25 Robert Pitt Drive, Suite 204, Monsey, NY 10952, Rockland County. Our address on the Internet is www. incannex.com.au. The information on, or accessible through, our website is not part of this Registration Statement on Form 20-F. We have included our website address in this Registration Statement on Form 20-F solely as an inactive textual reference. All information we file with the U.S. Securities and Exchange Commission (“SEC”) is available through the SEC’s Electronic Data Gathering

Organizational Structure

Below is a list of our significant subsidiaries, including our ownership percentage, its date of formation and its jurisdiction. These subsidiaries were established to allow us to conduct commercial and clinical operations in Europe and the United States and expand our operations in Australia.

Property, Plants and Equipment

We own computer equipment, office furniture and laboratory equipment, which is primarily placed at our own offices and laboratories.

Management

Directors and Senior Management

The following table sets forth our directors and senior management, their age and the positions they held as of June 30, 2021. There are no family relationships among any of the members of our board of directors and our senior management.

Compensation

Remuneration Principles

Remuneration of all executive and non-executive directors and officers is determined by the board of directors.

We are committed to remunerating senior executives and executive directors in a manner that is market-competitive and consistent with “Best Practice” including the interests of shareholders. Remuneration packages are based on fixed and variable components, determined by the executives’ position, experience and performance, and may be satisfied via cash or equity.

Non-executive directors are remunerated out of the aggregate amount approved by shareholders and at a level that is consistent with industry standards. Non-executive directors do not receive performance-based bonuses and prior shareholder approval is required to participate in any issue of equity. No retirement benefits are payable other than statutory superannuation, if applicable.

Our remuneration policy is not directly based on our financial performance, rather on industry practice, given we operate in the biotechnology sector and our primary focus is research activities with a long-term objective of developing and commercializing the research and development results.

We envisage our performance in terms of earnings will remain negative while we continue in the research and development phase.

The purpose of a performance bonus is to reward individual performance in line with our objectives. Consequently, performance-based remuneration is paid to an individual where the individual’s performance clearly contributes to a successful outcome. This is regularly measured in respect of performance against key performance indicators.

We use a variety of key performance indicators to determine achievement, depending on the role of the executive being assessed. These include:

•        successful contract negotiations;

•        achievement of research project milestones within scheduled time and/or budget; and

•        our share price reaching a targeted level on the ASX over a period of time.

Board Practices

Introduction

Our Board of Directors is elected by and accountable to our shareholders. It currently consists of four directors, including three non-executive directors, of which one is the non-executive Chairman of our Board of Directors. The Chairman of our Board of Directors is responsible for the management of the Board of Directors and its functions.

Election of Directors

Directors are elected at our annual general meeting of shareholders. Under our Constitution, a director, other than a managing director, must not hold office for more than three years or beyond the third annual general meeting following his appointment (whichever is the longer period) without submitting himself for re-election. Our Board of Directors has the power to appoint any person to be a director, either to fill a vacancy or as an additional director (provided that the total number of directors does not exceed the maximum allowed by law), and any director so appointed may hold office only until the next annual general meeting (“AGM”) when he or she shall be eligible for election.

The appointment and expiration dates of each director in office on June 30, 2020, is as follows:

____________

(1)      According to our Constitution, a Managing Director’s appointment is not subject to expiration.

(2)      Term expires on the date of the AGM for that year.

Corporate Governance

ASX Corporate Governance Principles

In Australia, there are no defined corporate governance structures and practices that must be observed by a company listed on the ASX, except that entities of a certain size are required to have audit and remuneration committees and, in some instances, trading policies for key management personnel. Instead, the ASX Corporate Governance Council has published the Corporate Governance Principles and Recommendations, which contains what are called the Recommendations which articulate eight core principles which are intended to provide a reference point for companies about their corporate governance structures and practices. Under ASX Listing Rule 4.10.3, companies are required to attach a copy of the Company’s corporate governance statement (which has been approved by the Board) and provide a statement in their annual report to shareholders disclosing the extent to which they have followed the Recommendations in the reporting period and where they have not followed all the Recommendations, identify the Recommendations that have not been followed, and the reasons for not following them and what (if any) alternative governance practices it adopted in lieu of the recommendations during that period. It is not mandatory to follow the Recommendations. As compliance with the Recommendations would entail excessive costs to us, and in light of our current size, we do not follow the Recommendations because the costs of doing so would outweigh the benefits.

Non-Executive and Independent Directors

Australian law does not require a company to appoint a certain number of independent directors to its board of directors or audit committee. However, under the Corporate Governance Principles and Recommendations, the ASX recommends, but does not require, that an ASX-listed company have a majority of independent directors on its board of directors. Our Board of Directors has determined that each of Troy Valentine and Peter Widdows qualifies as an independent director under the requirements of the ASX.

Our Board of Directors does not have regularly scheduled meetings at which only independent directors are present. The Board of Directors does meet regularly and independent directors are expected to attend all such meetings.

Committees of the Board of Directors

Audit Committee.    Nasdaq Marketplace Rules require us to establish an audit committee comprised of at least three members, each of whom is financially literate and satisfies the respective “independence” requirements of the SEC and Nasdaq and one of whom has accounting or related financial management expertise at senior levels within a company.

Our Audit Committee assists our Board of Directors in overseeing the accounting and financial reporting processes of our company and audits of our financial statements, including the integrity of our financial statements, compliance with legal and regulatory requirements, our independent public accountants’ qualifications and independence, and independent public accountants, and such other duties as may be directed by our Board of Directors. The Audit Committee is also required to assess risk management.

Our Audit Committee currently consists of two board members, Peter Widdows and Troy Valentine. Each of Troy Valentine and Peter Widdows satisfies the “independence” requirements of the U.S. Securities and Exchange Commission and Nasdaq Marketplace Rules. As permitted by Nasdaq Marketplace Rules, we will appoint a third independent board member to the audit committee within 1 year of listing on Nasdaq. The audit committee meets at least two times per year.

Corporate Governance Requirements under Nasdaq listing rules.

As we are incorporated in Australia, we are allowed to follow Australian “home country” corporate governance practices in lieu of the otherwise applicable Nasdaq corporate governance standards, as long as we disclose each requirement of Rule 5600 that we do not follow and describe the home country practice we follow in lieu of the relevant Nasdaq corporate governance standards. We intend to take all actions necessary to maintain compliance with applicable corporate governance requirements under the rules adopted by the SEC and listing standards of Nasdaq. We follow Australian corporate governance practices in lieu of the corporate governance requirements of the Nasdaq Marketplace Rules in respect of:

•        Nasdaq requirement under Rule 5605(d) that a compensation committee be constituted — The ASX Listing Rules do not have an express requirement that each issuer listed on ASX have a compensation committee. We expect to rely on an exemption from the requirement to constitute a compensation committee under the Nasdaq listing rules and we seek to claim such exemption.

•        Nasdaq requirement under Rule 5605(e) that a nominations committee be constituted — The ASX Listing Rules do not have an express requirement that each issuer listed on ASX have a nominations committee. We expect to rely on an exemption from the requirement to constitute a nominations committee under the Nasdaq listing rules and we seek to claim such exemption.

•        Nasdaq requirement under Rule 5620(c) that a quorum consist of holders of 33 1/3% of the outstanding ordinary shares — The ASX Listing Rules do not have an express requirement that each issuer listed on ASX have a quorum of any particular number of the outstanding ordinary shares, but instead allow a listed issuer to establish its own quorum requirements. Our quorum is currently two persons who are entitled to vote. We believe this quorum requirement is consistent with the requirements of the ASX and is appropriate and typical of generally accepted business practices in Australia.

•        Nasdaq requirements under Rules 5605(b)(1) and (2) relating to director independence, including the requirements that a majority of the board of directors must be comprised of independent directors and that independent directors must have regularly scheduled meetings at which only independent directors are present — The Nasdaq and ASX definitions of what constitute an independent director are not identical and the requirements relating to the roles and obligations of independent directors are not identical. The ASX, unlike Nasdaq, permits an issuer to establish its own materiality threshold for determining whether a transaction between a director and an issuer affects the director’s status as independent and it does not require that a majority of the issuer’s board of directors be independent, as

long as the issuer publicly discloses this fact. In addition, the ASX does not require that the independent directors have regularly scheduled meeting at which only independent directors are present. We believe that our Board composition is consistent with the requirements of the ASX and that it is appropriate and typical of generally accepted business practices in Australia.

•        The requirement that our independent directors meet regularly in executive sessions under Nasdaq Listing Rules. The ASX Listing Rules and the Corporations Act do not require the independent directors of an Australian company to have such executive sessions.

•        The Nasdaq requirements under Rules 5605(d) that compensation of an issuer’s officers must be determined, or recommended to the Board for determination, either by a majority of the independent directors, or a compensation committee comprised solely of independent directors, and that director nominees must either be selected, or recommended for the Board’s selection, either by a majority of the independent directors, or a nominations committee comprised solely of independent directors. The Nasdaq compensation committee requirements are not identical to the ASX remuneration and nomination committee requirements. Issuers listed on the ASX are recommended under applicable listing standards to establish a remuneration committee consisting of a majority of independent directors and an independent chairperson, or publicly disclose that it has not done so. We do not have a compensation committee.

•        The requirement prescribed by Nasdaq Listing Rules that issuers obtain shareholder approval prior to the issuance of securities in connection with certain acquisitions, private placements of securities, or the establishment or amendment of certain share option, purchase or other compensation plans. Applicable Australian law and the ASX Listing Rules differ from Nasdaq requirements, with the ASX Listing Rules providing generally for prior shareholder approval in numerous circumstances, including (i) issuance of equity securities exceeding 15% (or 25% under certain circumstances) of our issued share capital in any 12-month period (but, in determining the 15% limit, securities issued under an exception to the rule or with shareholder approval are not counted), (ii) issuance of equity securities to related parties (as defined in the ASX Listing Rules) and (iii) issuances of securities to directors or their associates under an employee incentive plan.

Indemnification of Directors and Officers

Our Constitution provides that, we may indemnify a person who is, or has been, a director or an officer of our company, to the full extent permissible by law, out of our property against any liability incurred by such person as a director or an officer in defending proceedings, whether civil or criminal, and whatever their outcome.

In addition, our Constitution provides that to the extent permitted by law, we may pay, or agree to pay, a premium in respect of a contract insuring a person who is or has been a director or an officer of our company or one of our subsidiaries against any liability:

•        incurred by the person in his or her capacity as a director or an officer of our company or a subsidiary of our company, and

•        for costs and expenses incurred by that person in defending proceedings relating to that person acting as a director or an officer of Incannex, whether civil or criminal, and whatever their outcome.

We maintain a directors’ and officers’ liability insurance policy. We have established a policy for the indemnification of our directors and officers against certain liabilities incurred as a director or officer, including costs and expenses associated in successfully defending legal proceedings

Employees

As of June 30, 2021, we had 4 employees. Of these employees, 3 were employed in research and development and 1 in general management and administration. All the employees were located in Australia. As at the end of fiscal year 2020, we had 4 employees.

Each of our full-time employees has entered into an agreement with an unlimited term. We may only terminate the employment of any of our employees in accordance with the relevant employee’s contract of employment.

Our standard contract of employment for full time provides that we can terminate the employment of an employee without notice for serious misconduct or with between one to six months’ notice without cause (as set out in the relevant employee’s contract of employment).

Certain Relationships and Related Party Transactions

The following is a description of our related party transactions since July 1, 2018.

In fiscal years 2021, 2020 and 2019, respectively, the Company paid A$97,976, A$145,200 and A$115,864 in fees to Alignment Capital Pty Ltd (“Alignment”), an entity controlled by our Chairman Troy Valentine, as consideration for its services as lead manager.

In June 2019, the Company borrowed A$15,000 from Joel Latham, our Chief Executive Officer, and A$50,000 from Alignment to secure funds to continue the Company’s operations while in the process of completing a capital raising. These funds were advanced with no interest or security element. These amounts were fully repaid by June 30, 2019.

In March 2019, we entered into a distribution agreement with Cannvalate Pty Ltd, a company in which Dr. Sud Agarwal is a director and major shareholder. Under the terms of the agreement, we had the right to distribute cannabinoid oil products in Australia through Cannvalate’s network. This agreement was terminated on June 30, 2021.

Principal Shareholders

The following table presents the beneficial ownership of our ordinary shares based on 1,065,859,479 ordinary shares outstanding at June 30, 2021 by each person known by us to be the beneficial owner of more than 5% of our ordinary shares.

We have determined beneficial ownership in accordance with the rules and regulations of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Except as indicated by the footnotes below, we believe, based on information furnished to us, that the persons and entities named in the table below have sole voting and sole investment power with respect to all shares that they beneficially own.

Applicable percentage ownership before the offering is based on 1,065,859,479 ordinary shares outstanding as of June 30, 2021. Applicable percentage ownership after the offering is based on ordinary shares outstanding immediately after the closing of this offering (after giving effect to the sale and issuance of ADSs representing            ordinary shares at an ADS-to-ordinary share ratio of 1-to-50), assuming no exercise by the underwriter of its option to purchase additional ADSs. In computing the number of shares beneficially owned by a person or entity and the percentage ownership of such person or entity, we deemed to be outstanding all shares subject to options and warrants held by the person or entity that are currently exercisable, or exercisable within 60 days of June 30, 2021. However, except as described above, we did not deem such shares outstanding for the purpose of computing the percentage ownership of any other person or entity.

____________

(1)      Includes 34,303,593 ordinary shares, 200,000,000 options to purchase ordinary shares and 32,000,000 ordinary shares owned by Cannvalate, in which Dr. Sud Agarwal owns approximately 30% and is Chairman and, as such, may be deemed to have voting and dispositive power with respect to the ordinary shares in Incannex held by Cannvalate.

As of December 31, 2020, there were 4,204 holders of record of our ordinary shares, of which 1 holder, holding approximately 0.003% of our ordinary shares, had registered addresses in the United States. These numbers are not representative of the number of beneficial holders of our shares nor are they representative of where such beneficial holders reside, as many of these ordinary shares were held of record by brokers or other nominees.

To our knowledge, we are not directly or indirectly controlled by another corporation, by any foreign government or by any other natural or legal person severally or jointly. There are no agreements known to us, the operation of which may at a subsequent date result in a change in control of Incannex. All shareholders have the same voting rights.

Memorandum and Articles of Association

General

Our constituent document is a Constitution. The Constitution is subject to the terms of the Listing Rules of ASX Limited and the Corporations Act 2001. The Constitution may be amended or repealed and replaced by special resolution of shareholders, which is a resolution of which notice has been given and that has been passed by at least 75% of the votes cast by shareholders entitled to vote on the resolution.

Purposes and Objects

As a public company we have all the rights, powers and privileges of a natural person. Our Constitution does not provide for or prescribe any specific objects or purposes.

The Powers of the Directors

Under the provision of our Constitution our directors may exercise all the powers of our company except any powers that the Corporations Act or the constitution attributes to Incannex.

Interested Directors

According to our constitution, if a Director discloses his or her in accordance with the Corporations Act, the director may (i) contract or make an arrangement with the Company, or a related body corporate of the Company or a body corporate in which the Company is interested, in any matter in any capacity, (ii) be counted in a quorum for a meeting of Directors considering the contract or arrangement, (iii) vote on whether the Company enters into the contract or arrangement, and on any matter that relates to the contract or arrangement, (iv) sign on behalf of the Company, or witness the affixing of the common seal of the Company to, any document in respect of the contract or arrangement, (v) retain the benefits under the contract or arrangement.

Unless a relevant exception applies, the Corporations Act requires our directors to provide disclosure of certain interests or conflicts of interests and prohibits directors from voting on matters in which they have a material personal interest and from being present at the meeting while the matter is being considered. In addition, the Corporations Act and the ASX Listing Rules require shareholder approval of any provision of related party benefits to our directors.

Directors’ compensation

Our non-executive directors are paid remuneration for their services as directors which is determined in a general meeting of shareholders. The aggregate, fixed sum for directors’ remuneration is to be divided among the directors in such proportion as the directors themselves agree and in accordance with our Constitution. Our executive directors are paid remuneration for their services as directors which is determined by all directors.

Fees payable to our non-executive directors must be by way of a fixed sum and not by way of a commission on or a percentage of profits or operating revenue. Remuneration paid to our executive directors must also not include a commission or percentage of operating revenue.

Pursuant to our Constitution, any director who performs services that in the opinion of our board of directors, are outside the scope of the ordinary duties of a director may be paid extra remuneration, which is determined by our board of directors.

In addition to other remuneration provided in our Constitution, all of our directors are entitled to be paid by us for reasonable travel accommodation and other expenses incurred by the directors in attending general meetings, board meetings, committee meetings or otherwise in connection with our business.

In addition, in accordance with our Constitution, a director may be paid a retirement benefit as determined by our board of directors subject to the limits set out in the Corporations Act and the ASX Listing Rules which broadly restrict our ability to pay our officers a termination benefit in the event of a change of control of the Company or our subsidiaries as well as impose requirements for shareholder approval to be obtained to pay certain retirement benefits to our officers.

Borrowing powers exercisable by Directors

Pursuant to our Constitution, the management and control of our business affairs are vested in our board of directors. Thus, our board of directors has the power to raise or borrow money, and charge any of our property or business or any uncalled capital, and may issue debentures or give any other security for any of our debts, liabilities or obligations or of any other person, in each case, in the manner and on terms it deems fit.

Retirement of Directors

Pursuant to our Constitution and the ASX Listing Rules, each director, other than the managing director, must not hold office for more than three years or beyond the third annual general meeting following his or her appointment (whichever is longer). Further, at least one director is required to retire by rotation at each annual general meeting (such director being the director who has been longest in office since their last election). Directors who retire by rotation are eligible for a re-election to the board of directors unless disqualified from acting as a director under the Corporations Act or our Constitution.

Rights Attached to Our Ordinary Shares

The concept of authorized share capital no longer exists in Australia and as a result, our authorized share capital is unlimited. All our outstanding ordinary shares are validly issued, fully paid and non-assessable. The rights attached to our ordinary shares are as follows:

Dividend Rights.

The directors may declare that a dividend be paid to the members according to the shareholders’ pro rata shareholdings and the directors may fix the amount, the time for payment and the method of payment. No dividend is payable except in accordance with the Corporations Act as amended from time to time and no dividend carries interest as against the Company.

Voting Rights.

Holders of ordinary shares have one vote for each ordinary share held on all matters submitted to a vote of shareholders. Such voting rights may be affected by the grant of any special voting rights to the holders of a class of shares with preferential rights that may be authorized in the future.

The quorum required for an ordinary meeting of shareholders consists of at least two shareholders present in person, or by proxy, attorney or representative appointed pursuant to our Constitution. A meeting adjourned for lack of a quorum generally is adjourned to the same day in the following week at the same time and place. At the reconvened meeting, the required quorum consists of any two members present in person, or by proxy, attorney or representative appointed pursuant to our Constitution. The meeting is dissolved if a quorum is not present within 30 minutes from the time appointed for the meeting.

An ordinary resolution, such as a resolution for the declaration of dividends, requires approval by the holders of a majority of the voting rights represented at the meeting, in person, by proxy, or by written ballot and voting thereon. Under our Constitution, the Corporations Act and the ASX Listing Rules, certain matters must be passed by way of a special resolution. A special resolution must be passed by at least 75% of the votes cast by shareholders entitled to vote on the resolution and who vote at the meeting in person. Matters which are not required to be passed by special resolution are required to be passed by ordinary resolution.

Description of American Depositary Shares

American Depositary Shares

Deutsche Bank Trust Company Americas, as depositary, will register and deliver the ADSs. Each ADS will represent ownership of 50 ordinary shares, deposited with National Nominees Limited, as custodian for the depositary. Each ADS will also represent ownership of any other securities, cash or other property which may be held by the depositary. The depositary’s corporate trust office at which the ADSs will be administered is located at 60 Wall Street, New York, NY 10005, USA. The principal executive office of the depositary is located at 60 Wall Street, New York, NY 10005, USA.

The Direct Registration System, or DRS, is a system administered by The Depository Trust Company, or DTC, pursuant to which the depositary may register the ownership of uncertificated ADSs, which ownership shall be evidenced by periodic statements issued by the depositary to the ADS holders entitled thereto.

We will not treat ADS holders as our shareholders and accordingly, you, as an ADS holder, will not have shareholder rights. Australian law governs shareholder rights. The depositary will be the holder of the ordinary shares underlying your ADSs. As a holder of ADSs, you will have ADS holder rights. A deposit agreement among us, the depositary and you, as an ADS holder, and the beneficial owners of ADSs sets out ADS holder rights as well as the rights and obligations of the depositary. The laws of the State of New York govern the deposit agreement and the ADSs. See “— Jurisdiction and Arbitration.”

The following is a summary of the material provisions of the deposit agreement. For more complete information, you should read the entire deposit agreement and the form of American Depositary Receipt. For directions on how to obtain copies of those documents, see “Where You Can Find Additional Information.”

Holding the ADSs

How will you hold your ADSs?

You may hold ADSs either (i) directly (a) by having an American Depositary Receipt, or ADR, which is a certificate evidencing a specific number of ADSs, registered in your name, or (b) by holding ADSs in DRS, or (ii) indirectly through your broker or other financial institution. If you hold ADSs directly, you are an ADS holder. This description assumes you hold your ADSs directly. ADSs will be issued through DRS, unless you specifically request certificated ADRs. If you hold the ADSs indirectly, you must rely on the procedures of your broker or other financial institution to assert the rights of ADS holders described in this section. You should consult with your broker or financial institution to find out what those procedures are.

Dividends and Other Distributions

How will you receive dividends and other distributions on the shares?

The depositary has agreed to pay to you the cash dividends or other distributions it or the custodian receives on ordinary shares or other deposited securities, after deducting its fees and expenses. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent as of the record date (which will be as close as practicable to the record date for our ordinary shares) set by the depositary with respect to the ADSs.

•        Cash.    The depositary will convert or cause to be converted any cash dividend or other cash distribution we pay on the ordinary shares or any net proceeds from the sale of any ordinary shares, rights, securities or other entitlements under the terms of the deposit agreement into U.S. dollars if it can do so on a practicable basis and can transfer the U.S. dollars to the United States and will distribute promptly the amount thus received. If the depositary shall determine in its judgment that such conversions or transfers are not practical or lawful or if any government approval or license is needed and cannot be obtained at a reasonable cost within a reasonable period or otherwise sought, the deposit agreement allows the depositary to distribute the foreign currency only to those ADS holders to whom it is possible to do so. It will hold or cause the custodian to hold the foreign currency it cannot convert for the account of the ADS holders who have not been paid and such funds will be held for the respective accounts of the ADS holders. It will not invest the foreign currency and it will not be liable for any interest for the respective accounts of the ADS holders.

Before making a distribution, any taxes or other governmental charges, together with fees and expenses of the depositary, that must be paid, will be deducted. See “Taxation.” It will distribute only whole U.S. dollars and cents and will round down fractional cents to the nearest whole cent. If the exchange rates fluctuate during a time when the depositary cannot convert the foreign currency, you may lose some or all of the value of the distribution.

•        Shares.    For any ordinary shares we distribute as a dividend or free distribution, either (1) the depositary will distribute additional ADSs representing such ordinary shares or (2) existing ADSs as of the applicable record date will represent rights and interests in the additional ordinary shares distributed, to the extent reasonably practicable and permissible under law, in either case, net of applicable fees, charges and expenses incurred by the depositary and taxes and/or other governmental charges. The depositary will only distribute whole ADSs. It will try to sell ordinary shares which would require it to deliver a fractional ADS and distribute the net proceeds in the same way as it does with cash. The depositary may sell a portion of the distributed ordinary shares sufficient to pay its fees and expenses, and any taxes and governmental charges, in connection with that distribution.

•        Elective Distributions in Cash or Shares.    If we offer holders of our ordinary shares the option to receive dividends in either cash or shares, the depositary, after consultation with us and having received timely notice as described in the deposit agreement of such elective distribution by us, has discretion to determine to what extent such elective distribution will be made available to you as a holder of the ADSs. We must timely first instruct the depositary to make such elective distribution available to you and furnish it with satisfactory evidence that it is legal to do so. The depositary could decide it is not legal or reasonably practicable to make such elective distribution available to you. In such case, the depositary shall, on the basis of the same determination as is made in respect of the ordinary shares for which no election is made, distribute either cash in the same way as it does in a cash distribution, or additional ADSs representing ordinary shares in the same way as it does in a share distribution. The depositary is not obligated to make available to you a method to receive the elective dividend in shares rather than in ADSs. There can be no assurance that you will be given the opportunity to receive elective distributions on the same terms and conditions as the holders of ordinary shares.

•        Rights to Purchase Additional Shares.    If we offer holders of our ordinary shares any rights to subscribe for additional shares, the depositary shall having received timely notice as described in the deposit agreement of such distribution by us, consult with us, and we must determine whether it is lawful and reasonably practicable to make these rights available to you. We must first instruct the depositary to make such rights available to you and furnish the depositary with satisfactory evidence that it is legal to do so. If the depositary decides it is not legal or reasonably practicable to make the rights available but that it is lawful and reasonably practicable to sell the rights, the depositary will endeavor to sell the rights and in a riskless principal capacity or otherwise, at such place and upon such terms (including public or private sale) as it may deem proper distribute the net proceeds in the same way as it does with cash.

The depositary will allow rights that are not distributed or sold to lapse. In that case, you will receive no value for them.

If the depositary makes rights available to you, it will establish procedures to distribute such rights and enable you to exercise the rights upon your payment of applicable fees, charges and expenses incurred by the depositary and taxes and/or other governmental charges. The Depositary shall not be obliged to make available to you a method to exercise such rights to subscribe for ordinary shares (rather than ADSs).

U.S. securities laws may restrict transfers and cancellation of the ADSs represented by shares purchased upon exercise of rights. For example, you may not be able to trade these ADSs freely in the United States. In this case, the depositary may deliver restricted depositary shares that have the same terms as the ADSs described in this section except for changes needed to put the necessary restrictions in place.

There can be no assurance that you will be given the opportunity to exercise rights on the same terms and conditions as the holders of ordinary shares or be able to exercise such rights.

•        Other Distributions.    Subject to receipt of timely notice, as described in the deposit agreement, from us with the request to make any such distribution available to you, and provided the depositary has determined such distribution is lawful and reasonably practicable and feasible and in accordance with the terms of the deposit agreement, the depositary will distribute to you anything else we distribute on deposited securities by any means it may deem practicable, upon your payment of applicable fees, charges and expenses incurred by the depositary and taxes and/or other governmental charges. If any of the conditions above are not met, the depositary will endeavor to sell, or cause to be sold, what we distributed and distribute the net proceeds in the same way as it does with cash; or, if it is unable to sell such property, the depositary may dispose of such property in any way it deems reasonably practicable under the circumstances for nominal or no consideration, such that you may have no rights to or arising from such property.

The depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any ADS holders. We have no obligation to register ADSs, shares, rights or other securities under the Securities Act. We also have no obligation to take any other action to permit the distribution of ADSs, shares, rights or anything else to ADS holders. This means that you may not receive the distributions we make on our shares or any value for them if we and/or the depositary determines that it is illegal or not practicable for us or the depositary to make them available to you.

Deposit, Withdrawal and Cancellation

How are ADSs issued?

The depositary will deliver ADSs if you or your broker deposit ordinary shares or evidence of rights to receive ordinary shares with the custodian. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will register the appropriate number of ADSs in the names you request and will deliver the ADSs to or upon the order of the person or persons entitled thereto.

Except for ordinary shares deposited by us in connection with this offering, no shares will be accepted for deposit prior to the date of this prospectus.

How do ADS holders cancel an American Depositary Share?

You may turn in your ADSs at the depositary’s corporate trust office or by providing appropriate instructions to your broker. Upon payment of its fees and expenses and of any taxes or charges, such as stamp taxes or stock transfer taxes or fees, the depositary will deliver the ordinary shares and any other deposited securities underlying the ADSs to you or a person you designate at the office of the custodian. Or, at your request, risk and expense, the depositary will deliver the deposited securities at its corporate trust office, to the extent permitted by law.

How do ADS holders interchange between Certificated ADSs and Uncertificated ADSs?

You may surrender your ADR to the depositary for the purpose of exchanging your ADR for uncertificated ADSs. The depositary will cancel that ADR and will send you a statement confirming that you are the owner of uncertificated ADSs. Alternatively, upon receipt by the depositary of a proper instruction from a holder of uncertificated ADSs requesting the exchange of uncertificated ADSs for certificated ADSs, the depositary will execute and deliver to you an ADR evidencing those ADSs.

Voting Rights

How do you vote?

You may instruct the depositary to vote the ordinary shares or other deposited securities underlying your ADSs at any meeting at which you are entitled to vote pursuant to any applicable law, the provisions of our constitution, and the provisions of or governing the deposited securities. Otherwise, you could exercise your right to vote directly if you withdraw the ordinary shares. However, you may not know about the meeting sufficiently enough in advance to withdraw the ordinary shares.

If we ask for your instructions and upon timely notice from us by regular, ordinary mail delivery, or by electronic transmission, as described in the deposit agreement, the depositary will notify you of the upcoming meeting at which you are entitled to vote pursuant to any applicable law, the provisions of our constitution, and the provisions of or governing the deposited securities, and arrange to deliver our voting materials to you. The materials will include or reproduce (a) such notice of meeting or solicitation of consents or proxies; (b) a statement that the ADS holders at the close of business on the ADS record date will be entitled, subject to any applicable law, the provisions of our constitution, and the provisions of or governing the deposited securities, to instruct the depositary as to the exercise of the voting rights, if any, pertaining to the ordinary shares or other deposited securities represented by such holder’s ADSs; and (c) a brief statement as to the manner in which such instructions may be given to the depositary. Voting instructions may be given only in respect of a number of ADSs representing an integral number of ordinary shares or other deposited securities. For instructions to be valid, the depositary must receive them in writing on or before the date specified. The depositary will try, as far as practical, subject to applicable law and the provisions of our constitution, to vote or to have its agents vote the ordinary shares or other deposited securities (in person or by proxy) as you instruct.

We cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote the ordinary shares underlying your ADSs. In addition, there can be no assurance that ADS holders and beneficial owners generally, or any holder or beneficial owner in particular, will be given the opportunity to vote or cause the custodian to vote on the same terms and conditions as the holders of our ordinary shares.

The depositary and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that you may not be able to exercise your right to vote and you may have no recourse if the ordinary shares underlying your ADSs are not voted as you requested.

In order to give you a reasonable opportunity to instruct the depositary as to the exercise of voting rights relating to deposited securities, if we request the depositary to act, we will give the depositary notice of any such meeting and details concerning the matters to be voted at least 28 Business Days in advance of the meeting date.

Compliance with Regulations

Information Requests

Each ADS holder and beneficial owner shall (a) provide such information as we or the depositary may request pursuant to law, including, without limitation, relevant Australian law, any applicable law of the United States of America, our constitution, any resolutions of our Board of Directors adopted pursuant to such constitution, the requirements of any markets or exchanges upon which the ordinary shares, ADSs or ADRs are listed or traded, or to any requirements of any electronic book-entry system by which the ADSs or ADRs may be transferred, regarding the capacity in which they own or owned ADRs, the identity of any other persons then or previously interested in such ADRs and the nature of such interest, and any other applicable matters, and (b) be bound by and subject to applicable provisions of the laws of the Australia, our constitution, and the requirements of any markets or exchanges upon which the ADSs, ADRs or ordinary shares are listed or traded, or pursuant to any requirements of any electronic book-entry system by which the ADSs, ADRs or ordinary shares may be transferred, to the same extent as if such ADS holder or beneficial owner held ordinary shares directly, in each case irrespective of whether or not they are ADS holders or beneficial owners at the time such request is made.

Disclosure of Interests

Each ADS holder and beneficial owner shall comply with our requests pursuant to Australian law, the rules and requirements of the Nasdaq and any other stock exchange on which the ordinary shares are, or will be, registered, traded or listed or our constitution, which requests are made to provide information, inter alia, as to the capacity in which such ADS holder or beneficial owner owns ADS and regarding the identity of any other person interested in such ADS and the nature of such interest and various other matters, whether or not they are ADS holders or beneficial owners at the time of such requests.

Fees and Expenses

As an ADS holder, you will be required to pay the following service fees to the depositary bank and certain taxes and governmental charges (in addition to any applicable fees, expenses, taxes and other governmental charges payable on the deposited securities represented by any of your ADSs):

As an ADS holder, you will also be responsible for paying certain fees and expenses incurred by the depositary bank and certain taxes and governmental charges (in addition to any applicable fees, expenses, taxes and other governmental charges payable on the deposited securities represented by any of your ADSs) such as:

•        Taxes (including applicable interest and penalties) and other governmental charges;

•        Fees for the transfer and registration of ordinary shares charged by the registrar and transfer agent for the ordinary shares in the Australian (i.e., upon deposit and withdrawal of ordinary shares).

•        Expenses incurred for converting foreign currency into U.S. dollars.

•        Expenses for cable, telex and fax transmissions and for delivery of securities.

•        Taxes and duties upon the transfer of securities, including any applicable stamp duties, any stock transfer charges or withholding taxes (i.e., when ordinary shares are deposited or withdrawn from deposit).

•        Fees and expenses incurred in connection with the delivery or servicing of ordinary shares on deposit.

•        Fees and expenses incurred in connection with complying with exchange control regulations and other regulatory requirements applicable to ordinary shares, deposited securities, ADSs and ADRs.

•        Any applicable fees and penalties thereon.

The depositary fees payable upon the issuance and cancellation of ADSs are typically paid to the depositary bank by the brokers (on behalf of their clients) receiving the newly issued ADSs from the depositary bank and by the brokers (on behalf of their clients) delivering the ADSs to the depositary bank for cancellation. The brokers in turn charge these fees to their clients. Depositary fees payable in connection with distributions of cash or securities to ADS holders and the depositary services fee are charged by the depositary bank to the holders of record of ADSs as of the applicable ADS record date.

The depositary fees payable for cash distributions are generally deducted from the cash being distributed or by selling a portion of distributable property to pay the fees. In the case of distributions other than cash (i.e., share dividends, rights), the depositary bank charges the applicable fee to the ADS record date holders concurrent with the distribution. In the case of ADSs registered in the name of the investor (whether certificated or uncertificated in direct registration), the depositary bank sends invoices to the applicable record date ADS holders. In the case of

ADSs held in brokerage and custodian accounts (via DTC), the depositary bank generally collects its fees through the systems provided by DTC (whose nominee is the registered holder of the ADSs held in DTC) from the brokers and custodians holding ADSs in their DTC accounts. The brokers and custodians who hold their clients’ ADSs in DTC accounts in turn charge their clients’ accounts the amount of the fees paid to the depositary banks.

In the event of refusal to pay the depositary fees, the depositary bank may, under the terms of the deposit agreement, refuse the requested service until payment is received or may set off the amount of the depositary fees from any distribution to be made to the ADS holder.

The depositary may make payments to us or reimburse us for certain costs and expenses, by making available a portion of the ADS fees collected in respect of the ADR program or otherwise, upon such terms and conditions as we and the depositary bank agree from time to time.

Payment of Taxes

You will be responsible for any taxes or other governmental charges payable, or which become payable, on your ADSs or on the deposited securities represented by any of your ADSs. The depositary may refuse to register or transfer your ADSs or allow you to withdraw the deposited securities represented by your ADSs until such taxes or other charges are paid. It may apply payments owed to you or sell deposited securities represented by your ADSs to pay any taxes owed and you will remain liable for any deficiency. If the depositary sells deposited securities, it will, if appropriate, reduce the number of ADSs to reflect the sale and pay to you any net proceeds, or send to you any property, remaining after it has paid the taxes. You agree to indemnify us, the depositary, the custodian and each of our and their respective agents, directors, employees and affiliates for, and hold each of them harmless from, any claims with respect to taxes (including applicable interest and penalties thereon) arising from any refund of taxes, reduced rate of withholding at source or other tax benefit obtained for you. Your obligations under this paragraph shall survive any transfer of ADRs, any surrender of ADRs and withdrawal of deposited securities or the termination of the deposit agreement.

Reclassifications, Recapitalizations and Mergers

Amendment and Termination

How may the deposit agreement be amended?

We may agree with the depositary to amend the deposit agreement and the form of ADR without your consent for any reason. If an amendment adds or increases fees or charges, except for taxes and other governmental charges or expenses of the depositary for registration fees, facsimile costs, delivery charges or similar items, including expenses incurred in connection with foreign exchange control regulations and other charges specifically payable by ADS holders under the deposit agreement, or materially prejudices a substantial existing right of ADS holders, it will not become effective for outstanding ADSs until 30 days after the depositary notifies ADS holders of the amendment. At the time an amendment becomes effective, you are considered, by continuing to hold your ADSs, to agree to the amendment and to be bound by the ADRs and the deposit agreement as amended. If any new laws are adopted which would require the deposit agreement to be amended in order to comply therewith, we and the depositary may amend the deposit agreement in accordance with such laws and such amendment may become effective before notice thereof is given to ADS holders.

How may the deposit agreement be terminated?

The depositary will terminate the deposit agreement if we ask it to do so, in which case the depositary will give notice to you at least 90 days prior to termination. The depositary may also terminate the deposit agreement if the depositary has told us that it would like to resign, or if we have removed the depositary, and in either case we have not appointed a new depositary within 90 days. In either such case, the depositary must notify you at least 30 days before termination.

After termination, the depositary and its agents will do the following under the deposit agreement but nothing else: collect distributions on the deposited securities, sell rights and other property and deliver ordinary shares and other deposited securities upon cancellation of ADSs after payment of any fees, charges, taxes or other governmental charges. Six months or more after the date of termination, the depositary may sell any remaining deposited securities by public or private sale. After that, the depositary will hold the money it received on the sale, as well as any other cash it is holding under the deposit agreement, for the pro rata benefit of the ADS holders that have not surrendered their ADSs. It will not invest the money and has no liability for interest. After such sale, the depositary’s only obligations will be to account for the money and other cash. After termination, we shall be discharged from all obligations under the deposit agreement except for our obligations to the depositary thereunder.

Books of Depositary

The depositary will maintain ADS holder records at its depositary office. You may inspect such records at such office during regular business hours but solely for the purpose of communicating with other holders in the interest of business matters relating to the Company, the ADRs and the deposit agreement.

The depositary will maintain facilities in the Borough of Manhattan, The City of New York to record and process the issuance, cancellation, combination, split-up and transfer of ADRs.

These facilities may be closed at any time or from time to time when such action is deemed necessary or advisable by the depositary in connection with the performance of its duties under the deposit agreement or at our reasonable written request.

Limitations on Obligations and Liability

Limits on our Obligations and the Obligations of the Depositary and the Custodian; Limits on Liability to Holders of ADSs

The deposit agreement expressly limits our obligations and the obligations of the depositary and the custodian. It also limits our liability and the liability of the depositary. The depositary and the custodian:

•        are only obligated to take the actions specifically set forth in the deposit agreement without gross negligence or willful misconduct;

•        are not liable if any of us or our respective controlling persons or agents are prevented or forbidden from, or subjected to any civil or criminal penalty or restraint on account of, or delayed in, doing or performing any act or thing required by the terms of the deposit agreement and any ADR, by reason of any provision of any present or future law or regulation of the United States or any state thereof, the Commonwealth of Australia or any other country, or of any other governmental authority or regulatory authority or stock exchange, or on account of the possible criminal or civil penalties or restraint, or by reason of any provision, present or future, of our memorandum and articles of association or any provision of or governing any deposited securities, or by reason of any act of God or war or other circumstances beyond its control (including, without limitation, nationalization, expropriation, currency restrictions, work stoppage, strikes, civil unrest, revolutions, rebellions, explosions and computer failure);

•        are not liable by reason of any exercise of, or failure to exercise, any discretion provided for in the deposit agreement or in our memorandum and articles of association or provisions of or governing deposited securities;

•        are not liable for any action or inaction of the depositary, the custodian or us or their or our respective controlling persons or agents in reliance upon the advice of or information from legal counsel, any person presenting ordinary shares for deposit or any other person believed by it in good faith to be competent to give such advice or information;

•        are not liable for the inability of any holder of ADSs to benefit from any distribution on deposited securities that is not made available to holders of ADSs under the terms of the deposit agreement;

•        are not liable for any special, consequential, indirect or punitive damages for any breach of the terms of the deposit agreement, or otherwise;

•        may rely upon any documents we believe in good faith to be genuine and to have been signed or presented by the proper party;

•        disclaim any liability for any action or inaction or inaction of any of us or our respective controlling persons or agents in reliance upon the advice of or information from legal counsel, accountants, any person presenting ordinary shares for deposit, holders and beneficial owners (or authorized representatives) of ADSs, or any person believed in good faith to be competent to give such advice or information; and

•        disclaim any liability for inability of any holder to benefit from any distribution, offering, right or other benefit made available to holders of deposited securities but not made available to holders of ADS.

The depositary and any of its agents also disclaim any liability (i) for any failure to carry out any instructions to vote, the manner in which any vote is cast or the effect of any vote or failure to determine that any distribution or action may be lawful or reasonably practicable or for allowing any rights to lapse in accordance with the provisions of the deposit agreement, (ii) the failure or timeliness of any notice from us, the content of any information submitted to it by us for distribution to you or for any inaccuracy of any translation thereof, (iii) any investment risk associated with the acquisition of an interest in the deposited securities, the validity or worth of the deposited securities, the credit-worthiness of any third party, (iv) for any tax consequences that may result from ownership of ADSs, ordinary shares or deposited securities, or (v) for any acts or omissions made by a successor depositary, provided that in connection with the issue out of which such potential liability arises the depositary performed its obligations without gross negligence or wilful misconduct while it acted as depositary.

In the deposit agreement, we agree to indemnify the depositary under certain circumstances.

Jurisdiction and Arbitration

The laws of the State of New York govern the deposit agreement and the ADSs and we have agreed with the depositary that the federal or state courts in the City of New York shall have exclusive jurisdiction to hear and determine any dispute arising from or in connection with the deposit agreement and that the depositary will have the right to refer any claim or dispute arising from the relationship created by the deposit agreement to arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association. The arbitration provisions of the deposit agreement do not preclude you from pursuing claims under the Securities Act or the Exchange Act in federal or state courts.

Jury Trial Waiver

The deposit agreement provides that each party to the deposit agreement (including each holder, beneficial owner and holder of interests in the ADRs) irrevocably waives, to the fullest extent permitted by applicable law, any right it may have to a trial by jury in any lawsuit or proceeding against us or the depositary arising out of or relating to our shares, the ADSs or the deposit agreement, including any claim under the U.S. federal securities laws. If we or the depositary opposed a jury trial demand based on the waiver, the court would determine whether the waiver was enforceable based on the facts and circumstances of that case in accordance with the applicable law.

Requirements for Depositary Actions

Before the depositary will issue, deliver or register a transfer of an ADS, split-up, subdivide or combine ADSs, make a distribution on an ADS, or permit withdrawal of ordinary shares, the depositary may require:

•        payment of stock transfer or other taxes or other governmental charges and transfer or registration fees charged by third parties for the transfer of any ordinary shares or other deposited securities and payment of the applicable fees, expenses and charges of the depositary;

•        satisfactory proof of the identity and genuineness of any signature or any other matters contemplated in the deposit agreement; and

•        compliance with (A) any laws or governmental regulations relating to the execution and delivery of ADRs or ADSs or to the withdrawal or delivery of deposited securities and (B) such reasonable regulations and procedures as the depositary may establish, from time to time, consistent with the deposit agreement and applicable laws, including presentation of transfer documents.

The depositary may refuse to issue and deliver ADSs or register transfers of ADSs generally when the register of the depositary or our transfer books are closed or at any time if the depositary or we determine that it is necessary or advisable to do so.

Your Right to Receive the Shares Underlying Your ADSs

You have the right to cancel your ADSs and withdraw the underlying ordinary shares at any time except:

•        when temporary delays arise because: (1) the depositary has closed its transfer books or we have closed our transfer books; (2) the transfer of ordinary shares is blocked to permit voting at a shareholders’ meeting; or (3) we are paying a dividend on our ordinary shares;

•        when you owe money to pay fees, taxes and similar charges;

•        when it is necessary to prohibit withdrawals in order to comply with any laws or governmental regulations that apply to ADSs or to the withdrawal of ordinary shares or other deposited securities, or other circumstances specifically contemplated by Section I.A.(l) of the General Instructions to Form F-6 (as such General Instructions may be amended from time to time); or

•        for any other reason if the depositary or we determine, in good faith, that it is necessary or advisable to prohibit withdrawals.

The depositary shall not knowingly accept for deposit under the deposit agreement any ordinary shares or other deposited securities required to be registered under the provisions of the Securities Act, unless a registration statement is in effect as to such ordinary shares.

This right of withdrawal may not be limited by any other provision of the deposit agreement.

Direct Registration System

In the deposit agreement, all parties to the deposit agreement acknowledge that the DRS and Profile Modification System, or Profile, will apply to uncertificated ADSs upon acceptance thereof to DRS by DTC. DRS is the system administered by DTC pursuant to which the depositary may register the ownership of uncertificated ADSs, which ownership shall be evidenced by periodic statements issued by the depositary to the ADS holders entitled thereto. Profile is a required feature of DRS which allows a DTC participant, claiming to act on behalf of an ADS holder, to direct the depositary to register a transfer of those ADSs to DTC or its nominee and to deliver those ADSs to the DTC account of that DTC participant without receipt by the depositary of prior authorization from the ADS holder to register such transfer.

Shares Eligible for Future Sale

Upon completion of this offering, we will have            ADSs outstanding, representing            ordinary shares, or approximately            % of our outstanding ordinary shares, assuming the underwriter does not exercise its option to purchase additional ADSs. All of the ADSs sold in this offering will be freely transferable by persons other than our “affiliates” without restriction or further registration under the Securities Act. Sales of substantial amounts of the ADSs in the public market could adversely affect prevailing market prices of the ADSs. Prior to this offering, there has been no public market for the ADSs, and while we have applied to have the ADSs listed on the Nasdaq we cannot assure you that a regular trading market will develop in the ADSs.

Lock-up Agreements

Our directors and officers have agreed, subject to some exceptions, not to transfer or dispose of, directly or indirectly, any of our ordinary shares, in the form of ADSs or otherwise, or any securities convertible into or exchangeable or exercisable for our ordinary shares, in the form of ADSs or otherwise, for a period of 180 days after the date of this prospectus. After the expiration of the 180-day period, the ordinary shares or ADSs held by our directors, executive officers and our existing shareholders may be sold subject to the restrictions under Rule 144 under the Securities Act or by means of registered public offerings.

Rule 144

All of our ordinary shares outstanding prior to this offering are “restricted shares” as defined in Rule 144 under the Securities Act and may be sold publicly in the United States only if they are subject to an effective registration statement under the Securities Act or pursuant to an exemption from the registration requirements. Under Rule 144 as currently in effect, a person who has beneficially owned our restricted shares for at least six months is generally entitled to sell the restricted securities without registration under the Securities Act beginning 90 days after the date of this prospectus, subject to certain additional restrictions.

Our affiliates may sell within any three-month period a number of restricted shares that does not exceed the greater of the following:

•        1% of the then outstanding ordinary shares of the same class, in the form of ADSs or otherwise, which will equal approximately ordinary shares immediately after this offering, assuming the underwriter does not exercise its option to purchase additional ADSs; or

•        the average weekly trading volume of our ordinary shares in the form of ADSs or otherwise on the Nasdaq during the four calendar weeks preceding the date on which notice of the sale is filed with the SEC.

Affiliates who sell restricted securities under Rule 144 may not solicit orders or arrange for the solicitation of orders, and they are also subject to notice requirements and the availability of current public information about us.

Persons who are not our affiliates are only subject to one of these additional restrictions, the requirement of the availability of current public information about us, and this additional restriction does not apply if they have beneficially owned our restricted shares for more than one year.

Rule 701

In general, under Rule 701 of the Securities Act as currently in effect, each of our employees, consultants or advisors who purchases our ordinary shares from us in connection with a compensatory shares or option plan or other written agreement relating to compensation is eligible to resell such ordinary shares 90 days after we became a reporting company under the Exchange Act in reliance on Rule 144, but without compliance with some of the restrictions, including the holding period, contained in Rule 144.

Material United States Federal Income and Australian Tax Considerations

The following summary of the material Australian and U.S. federal income tax consequences of an investment in the ADSs or ordinary shares is based upon laws and relevant interpretations thereof in effect as of the date of this prospectus, all of which are subject to change, possibly with retroactive effect. This summary does not deal with all possible tax consequences relating to an investment in the ADSs or ordinary shares, such as the tax consequences under U.S. state, local and other tax laws other than U.S. federal income tax laws and certain Australian tax laws.

Holders of our ADSs should consult their own tax advisors as to the United States, Australian or other tax consequences of the purchase, ownership and disposition of ADSs, including, in particular, the effect of any foreign, state or local taxes.

Australian Taxation

In this section we discuss the material Australian tax considerations that apply to non-Australian tax residents with respect to the acquisition, ownership and disposal of the absolute beneficial ownership of ADSs, which are evidenced by ADSs. This discussion is based upon existing Australian tax law as of the date of this Registration Statement, which is subject to change, possibly retrospectively. This discussion does not address all aspects of Australian income tax law which may be important to particular investors in light of their individual investment circumstances, such as ADSs or shares held by investors subject to special tax rules (for example, financial institutions, insurance companies or tax exempt organizations). In addition, this summary does not discuss any foreign or state tax considerations, other than stamp duty. Prospective investors are urged to consult their tax advisors regarding the Australian and foreign income and other tax considerations of the purchase, ownership and disposition of the ADSs or shares.

Nature of ADSs for Australian Taxation Purposes

Holders of our ADSs are treated as the owners of the underlying ordinary shares for Australian income tax and capital gains tax purposes. Therefore, dividends paid on the underlying ordinary shares will be treated for Australian tax purposes as if they were paid directly to the owners of ADSs, and the disposal of ADSs will be treated for Australian tax purposes as the disposal of the underlying ordinary shares. In the following analysis we discuss the application of the Australian income tax and capital gains tax rules to non-Australian resident holders of ADSs.

Taxation of Dividends

Australia operates a dividend imputation system under which dividends may be declared to be “franked” to the extent they are paid out of company profits that have been subject to income tax. Fully franked dividends are not subject to dividend withholding tax. Dividends that are not franked or are partly franked and are paid to non-Australian resident shareholders are subject to dividend withholding tax, but only to the extent the dividends are not franked.

Dividends paid to a non-resident shareholder are subject to withholding tax (a) except to the extent they have been franked and (b) at 30%, unless the shareholder is a resident of a country with which Australia has a double taxation agreement.

In accordance with the provisions of the Double Taxation Convention between Australia and the United States, the maximum rate of Australian tax on any unfranked portion of a dividend to which a resident of the United States is beneficially entitled is 15%, where the U.S. resident holds less than 10% of the voting rights in our company, or 5% where the U.S. resident holds 10% or more of the voting rights in our company. Special rules apply to Regulated Investment Companies and Real Estate Investment Trusts that hold shares and receive dividends. The Double Taxation Convention between Australia and the United States does not apply to limit the tax rate on dividends where the ADSs are effectively connected to a permanent establishment or a fixed base carried on by the owner of the ADSs in Australia through which the shareholder carries on business or provides independent personal services, respectively.

Tax on Sales or other Dispositions of Shares — Capital Gains Tax

Australian capital gains derived by non-Australian residents in respect of the disposal of capital assets that are not taxable Australian property will be disregarded. Non-Australian resident shareholders will not be subject to Australian capital gains tax on the capital gain made on a disposal of our shares, unless they, together with associates, hold 10% or more of our issued capital, tested either at the time of disposal or over any continuous 12- month period in the 24 months prior to disposal, and the value of our shares at the time of disposal is principally attributable to Australian real property assets.

Australian capital gains tax applies to net capital gains at a taxpayer’s marginal tax rate but for certain shareholders a discount capital gain may apply if the shares have been held for 12 months or more. For individuals, this discount is 50%. Net capital gains are calculated after reduction for capital losses (including certain prior year capital losses), which may only be offset against capital gains.

Tax on Sales or other Dispositions of Shares — Shareholders Holding Shares on Revenue Account

Some non-Australian resident shareholders may hold shares on revenue rather than on capital account, for example, share traders. These shareholders may have the gains made on the sale or other disposal of the shares included in their assessable income under the ordinary income provisions of the income tax law, if the gains are sourced in Australia.

Non-Australian resident shareholders assessable under these ordinary income provisions in respect of gains made on shares held on revenue account would be assessed for such gains at the Australian tax rates for non-Australian residents, which start at a marginal rate of 32.5% for non-Australian resident individuals. Some relief from the Australian income tax may be available to such non-Australian resident shareholders under the Double Taxation Convention between the United States and Australia, for example, because the shareholder does not have a permanent establishment in Australia.

To the extent an amount would be included in a non-Australian resident shareholder’s assessable income under both the capital gains tax provisions and the ordinary income provisions, the capital gain amount would generally be reduced, so that the shareholder would not be subject to double tax on any part of the income gain or capital gain.

Dual Residency

If a shareholder were a resident of both Australia and the United States under those countries’ domestic taxation laws, that shareholder may be subject to tax as an Australian resident. If, however, the shareholder is determined to be a U.S. resident for the purposes of the Double Taxation Convention between the United States and Australia, the Australian tax applicable would be limited by the Double Taxation Convention. Shareholders should obtain specialist taxation advice in these circumstances.

Stamp Duty

A transfer of shares of a company listed on the Australian Securities Exchange is not subject to Australian stamp duty.

Australian Death Duty

Australia does not have estate or death duties. No capital gains tax liability is realized upon the inheritance of a deceased person’s shares. The disposal of inherited shares by beneficiaries, may, however, give rise to a capital gains tax liability.

Goods and Services Tax

The issue or transfer of shares will not incur Australian goods and services tax.

U.S. Taxation

The following is a summary of material U.S. federal income tax consequences that generally apply to U.S. Holders (as defined below) who hold ADSs as capital assets within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”). This summary is based on the Code, its legislative history, final,

temporary and proposed United States Treasury regulations promulgated thereunder, published rulings and court decisions, and the bilateral income tax convention between Australia and the United States (the “Treaty”), all as in effect on the date hereof and all of which are subject to change, or changes in interpretation, either prospectively or retroactively. This discussion does not address all of the tax consequences relating to the purchase, ownership, and disposition of ADSs and does not take into account U.S. Holders who may be subject to special rules, including: financial institutions, insurance companies, , tax-exempt organizations, real estate investment trusts, regulated investment companies, grantor trusts, non-resident aliens of the United States or taxpayers whose functional currency is not the U.S. dollar, persons who hold the ADSs through partnerships or other pass-through entities, persons who acquired their ADSs through the exercise or cancellation of any employee share options or otherwise as compensation for their services, investors that actually or constructively own 10% or more of our shares, dealers or traders in securities or currencies, certain former citizens or long-term residents of the United States, dual resident corporations, persons that generally mark their securities to market for United States federal income tax purposes, persons who are residents of Australia for Australian income tax purposes, and investors holding ADSs as part of a straddle or appreciated financial position or as part of a hedging or conversion transaction. This summary does not address the Medicare tax imposed on certain investment income, any state, local and foreign tax considerations or any U.S. federal estate, gift or alternative minimum tax considerations relevant to the purchase, ownership and disposition of our ADSs. In addition, this discussion is based in part upon representations of the depositary and the assumption that each obligation in the deposit agreement and any related agreements will be performed according to its terms.

If a partnership or an entity or arrangement treated as a partnership for U.S. federal income tax purposes owns ADSs, the U.S. federal income tax treatment of its partners will generally depend upon the status of the partner and the activities of the partnership. A partnership should consult its tax advisors regarding the U.S. federal income tax consequences applicable to it and its partners of the purchase, ownership and disposition of ADSs.

For purposes of this summary, the term “U.S. Holder” means a beneficial owner of ADSs that is for U.S. federal income tax purposes: an individual who is a citizen or resident of the United States; a corporation that is created or organized in or under the laws of the United States or any political subdivision thereof; an estate whose income is subject to U.S. federal income tax regardless of its source; or a trust if (a) a court within the United States is able to exercise primary supervision over administration of the trust, and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

Distributions

For U.S. federal income tax purposes, a U.S. Holder of ADSs will be treated as owning the ordinary shares underlying the ADSs. Subject to the passive foreign investment company rules discussed below, the gross amount of any distribution received by a U.S. Holder with respect to our ordinary shares or ADSs, including the amount of any Australian taxes withheld therefrom, will be included in gross income as a dividend to the extent the distribution is paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Distributions in excess of our earnings and profits will be treated first as a non-taxable return of capital to the extent of a U.S. Holder’s tax basis in the ADSs and thereafter will be treated as gain from the sale or exchange of the ADSs. We have not maintained and do not plan to maintain calculations of earnings and profits for U.S. federal income tax purposes. As a result, a U.S. Holder may need to include the entire amount of any such distribution in income as a dividend. Dividends will not, however, be eligible for the “dividends received deduction” generally allowed to corporate shareholders with respect to dividends received from U.S. corporations.

The U.S. dollar value of any distribution on the ADSs made in Australian dollars generally should be calculated by reference to the spot exchange rate between the U.S. dollar and the Australian dollar in effect on the date the distribution is actually or constructively received by the U.S. Holder regardless of whether the Australian dollars so received are in fact converted into U.S. dollars. A U.S. Holder who receives payment in Australian dollars and converts those Australian dollars into U.S. dollars at an exchange rate other than the rate in effect on such day may have a foreign currency exchange gain or loss, which would generally be treated as ordinary income or loss from sources within the United States for U.S. foreign tax credit purposes.

Subject to complex limitations and certain holding period requirements, a U.S. Holder may elect to claim a credit for Australian tax withheld from distributions against its U.S. federal income tax liability. The limitations set out in the Code include computational rules under which foreign tax credits allowable with respect to specific

classes of income cannot exceed the U.S. federal income taxes otherwise payable with respect to each such class of income. Dividends generally will be treated as foreign-source passive category income for U.S. foreign tax credit purposes or in the case of certain U.S. Holders as foreign source “general category” income. A U.S. Holder that does not elect to claim a U.S. foreign tax credit may instead claim a deduction for Australian tax withheld.

Subject to certain limitations, dividends received by a non-corporate U.S. Holder are subject to tax at a reduced maximum tax rate of 20 percent if the dividends are “qualified dividends”. Dividends are qualified dividends if: (a)(i) the issuer is entitled to benefits under the Treaty or (ii) the shares are readily tradable on an established securities market in the United States and (b) certain other requirements are met. We believe that we are entitled to benefits under the Treaty and that the ADSs currently are readily tradable on an established securities market in the United States. However, no assurance can be given that the ADSs will remain readily tradable. Further, the reduced rate does not apply to dividends if we are a PFIC in the year prior to or the year in which the dividend is paid.

The U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder of an ADS and the issuer of the security underlying the ADS may be taking actions that are inconsistent with the claiming of foreign tax credits for U.S. Holders of ADSs. Such actions would also be inconsistent with the claiming of the reduced rate of tax, described above, applicable to dividends received by certain non-corporate holders. Accordingly, the analysis of the creditability of Australian taxes and the availability of the reduced tax rate for dividends received by certain non-corporate holders, each described above, could be affected by actions taken by intermediaries in the chain of ownership between the holder of an ADS and our Company.

Disposition of ADSs

If you sell or otherwise dispose of ADSs, you will recognize gain or loss for U.S. federal income tax purposes in an amount equal to the difference between the U.S. dollar value of the amount realized on the sale or other disposition and your adjusted tax basis in the ADSs. Subject to the passive foreign investment company rules discussed below, such gain or loss generally will be capital gain or loss and will be long-term capital gain or loss if you have held the ADSs for more than one year at the time of the sale or other disposition. In general, any gain that you recognize on the sale or other disposition of ADSs will be gain from U.S. sources for purposes of the foreign tax credit limitation; losses will generally be allocated against U.S. source income. The deduction of capital losses is subject to certain limitations under the Code.

In the case of a cash-basis U.S. Holder who receives Australian dollars in connection with the sale or other disposition of ADSs, the amount realized will be calculated based on the U.S. dollar value of the Australian dollars received as determined by reference to the spot rate in effect on the settlement date of such exchange. A U.S. Holder who receives payment in Australian dollars and converts Australian dollars into U.S. dollars at a conversion rate other than the rate in effect on the settlement date may have foreign currency exchange gain or loss that would be treated as ordinary income or loss from sources within the United States for U.S. foreign tax credit purposes.

An accrual-basis U.S. Holder may elect the same treatment required of cash-basis taxpayers with respect to a sale or disposition of ADSs, provided that the election is applied consistently from year to year. Such election may not be changed without the consent of the Internal Revenue Service (“IRS”). In the event that an accrual-basis U.S. Holder does not elect to be treated as a cash-basis taxpayer (pursuant to the Treasury regulations applicable to foreign currency transactions), such U.S. Holder may have foreign currency gain or loss for U.S. federal income tax purposes because of differences between the U.S. dollar value of the currency received prevailing on the trade date and the settlement date. Any such currency gain or loss would be treated as ordinary income or loss from sources within the United States for U.S. foreign tax credit purposes. However, if foreign currency is converted into U.S. dollars on the date received by the U.S. Holder, a cash-basis or electing accrual-basis U.S. Holder should not recognize any gain or loss on such conversion.

Passive Foreign Investment Companies

There is a risk that we may be a passive foreign investment company(“PFIC”), for U.S. federal income tax purposes. Our treatment as a PFIC could result in a reduction in the after-tax return to the U.S. Holders of our ADSs and may cause a reduction in the value of such securities.

For U.S. federal income tax purposes, we will be classified as a PFIC for any taxable year in which (i) 75% or more of our gross income is passive income, or (ii) at least 50% of the average value of all of our assets for the taxable year produce or are held for the production of passive income. For this purpose, cash is considered to be an asset which produces passive income. Passive income for these purposes generally includes dividends, interest, royalties, rents, annuities and the excess of gains over losses from the disposition of assets which produce passive income. In making a PFIC determination, we will be treated as owning our proportionate share of the assets and earning our proportionate share of the income of any other corporation in which we own, directly or indirectly, 25% or more (by value) of the share capital. Based on the composition of our assets and income, we believe that we should not be treated as a PFIC for U.S. federal income tax purposes with respect to fiscal year 2020. However, the determination of PFIC status is a factual determination that must be made annually at the close of each taxable year and, therefore, there can be no certainty as to our status in this regard until the close of the current or any future taxable year. Changes in the nature of our income or assets or a decrease in the trading price of our ADSs may cause us to be considered a PFIC in the current or any subsequent year. If we were a PFIC in any year during a U.S. Holder’s holding period for our ADSs, we would ordinarily continue to be treated as a PFIC for each subsequent year during which the U.S. Holder owned the ADSs.

Under the default PFIC “excess distribution” regime, if we are a PFIC in any taxable year during which a U.S. Holder owns ADSs, such U.S. Holder could be liable for additional taxes and interest charges upon (i) certain distributions by us (generally any distribution paid during a taxable year that is greater than 125 percent of the average annual distributions paid in the three preceding taxable years, or, if shorter, the U.S. Holder’s holding period for the ADSs), and (ii) any gain realized on a sale, exchange or other disposition, including a pledge, of the ADSs, whether or not we continue to be a PFIC for the year of the disposition. In these circumstances, the tax will generally be determined by allocating such distributions or gain ratably over the U.S. Holder’s holding period for the ADSs. The amount allocated to the current taxable year and any year prior to the first taxable year in which we are a PFIC will be taxed as ordinary income (rather than capital gain) earned in the current taxable year. The amount allocated to other taxable years will be taxed at the highest applicable marginal rates for the year and an interest charge at the rate applicable to underpayments of tax will also be imposed on the amount of taxes allocated to such other taxable years.

An indirect shareholder may be taxed on a distribution paid to the direct owner of a PFIC and on a disposition of the share indirectly owned. Indirect shareholders are strongly urged to consult their tax advisors regarding the application of these rules.

If we are a PFIC and subsequently cease to be a PFIC in a future year, a U.S. Holder may avoid the continued application of the tax treatment described above by electing to be treated as if it sold its ADSs on the last day of the last taxable year in which we were a PFIC. Any gain would generally be recognized and subject to tax under the excess distribution regime described above. Loss would not be recognized. A U.S. Holder’s basis in its ADSs would be increased by the amount of gain, if any, recognized on the deemed sale. A U.S. Holder would be required to treat its holding period for its ADSs as beginning on the day following the last day of the last taxable year in which we were a PFIC.

If the ADSs are considered “marketable stock” and if a U.S. Holder properly elects to “mark-to-market” its ADSs in a timely fashion, the U.S. Holder would not be subject to tax under the excess distribution regime described above. Instead, the U.S. Holder would generally include in income any excess of the fair market value of the ADSs at the close of each tax year over the adjusted tax basis of the ADSs. If the fair market value of the ADSs had depreciated below the adjusted basis at the close of the tax year, the U.S. Holder would be entitled to deduct the excess of the adjusted basis of the ADSs over their fair market value at that time. However, such deductions generally would be limited to the net mark-to-market gains, if any, the U.S. Holder included in income with respect to such ADSs in prior years. Income recognized and deductions allowed under the mark-to-market provisions, as well as any gain or loss on the disposition of ADSs with respect to which the mark-to-market election is made, is treated as ordinary income or loss (except that loss is treated as capital loss to the extent the loss exceeds the net mark-to-market gains, if any, that a U.S. Holder included in income with respect to such ordinary shares in prior years). However, gain or loss from the disposition of ADSs (as to which a “mark-to-market” election was properly made) in a year in which we are no longer a PFIC, will be capital gain or loss. Our ordinary shares or ADSs will be “marketable” stock as long as they remain regularly traded on a national securities exchange, such as the Nasdaq, or a foreign securities exchange regulated by a governmental authority of the country in which the market is located

and which meets certain requirements, including that the rules of the exchange effectively promote active trading of listed stocks. If such stock is traded on such a qualified exchange or other market, such stock generally will be “regularly traded” for any calendar year during which such stock is traded, other than in de minimis quantities, on at least 15 days during each calendar quarter, but no assurances can be given in this regard. Our ordinary shares are traded on the ASX, which may qualify as an eligible foreign securities exchange for this purpose. Because a mark-to-market election cannot be made for any lower-tier PFICs that we may own, a U.S. Holder may continue to be subject to the PFIC rules with respect to such holder’s indirect interest in any investments held by us that are treated as an equity interest in a PFIC for U.S. federal income tax purposes, including shares in any of our subsidiaries that are treated as PFICs.

A U.S. Holder of ADSs should not be able to avoid the tax consequences described above by electing to treat us as a qualified electing fund. In general, a qualified electing fund is, with respect to a U.S. person, a PFIC if the U.S. person has elected to include its proportionate share of a company’s ordinary earnings and net capital gains in U.S. income on an annual basis. A qualified electing fund election can only be made with respect to us if we provide U.S. Holders with certain information on an annual basis and we do not intend to prepare the information that U.S. Holders would need to make the qualified electing fund election.

Backup Withholding and Information Reporting

Payments in respect of ADSs may be subject to information reporting to the IRS and to U.S. backup withholding tax (at a rate of 24% under current law). Backup withholding will not apply, however, if a U.S. Holder (i) is a corporation, (ii) satisfies an applicable exemption, or (iii) furnishes correct taxpayer identification.

Backup withholding is not an additional tax. Amounts withheld under the backup withholding rules may be credited against a U.S. Holder’s U.S. tax liability, and a U.S. Holder may obtain a refund of any excess amounts withheld under the backup withholding rules by filing the appropriate claim for refund with the IRS.

Enforcement of Civil Liabilities

We are a public limited company incorporated under the laws of Australia. Certain of our directors are non-residents of the United States and substantially all of their assets are located outside the United States. As a result, it may not be possible or practicable for you to:

•        effect service of process within the United States upon our non-U.S. resident directors or on us;

•        enforce in U.S. courts judgments obtained against our non-U.S. resident directors or us in the United States courts in any action, including actions under the civil liability provisions of U.S. securities laws;

•        enforce in U.S. courts judgments obtained against our non-U.S. resident directors or us in courts of jurisdictions outside the United States in any action, including actions under the civil liability provisions of U.S. securities laws; or

•        bring an original action in an Australian court to enforce liabilities against our non-U.S. resident directors or us based solely upon U.S. securities laws.

You may also have difficulties enforcing in courts outside the United States judgments that are obtained in U.S. courts against any of our non-U.S. resident directors or us, including actions under the civil liability provisions of the U.S. securities laws.

With that noted, there are no treaties between Australia and the United States that would affect the recognition or enforcement of foreign judgments in Australia. We also note that investors may be able to bring an original action in an Australian court against us to enforce liabilities based in part upon U.S. federal securities laws. The disclosure in this section is not based on the opinion of counsel.

We have appointed Corporation Service Company as our agent to receive service of process with respect to any action brought against us under the federal securities laws of the United States.

Underwriting

We have entered into an underwriting agreement with the underwriter listed in the table below. We refer to the underwriter listed in the table below as the “underwriter.” Subject to the terms and conditions of the underwriting agreement, we have agreed to sell to the underwriter, and the underwriter has agreed to purchase from us, ADSs of the Company. Prior to this offering, there has been no public markets for the ADSs. We have applied to list the ADSs on the Nasdaq Capital Market under the symbol “IXHL”.

Pursuant to the terms and subject to the conditions contained in the underwriting agreement, we have agreed to sell to the underwriter named below, and the underwriter has agreed to purchase from us, the number of ADSs set forth opposite its name below:

The underwriting agreement provides that the obligation of the underwriter to purchase the ADSs offered by this prospectus is subject to certain conditions. The underwriter is obligated to purchase all of the ADSs offered hereby if any of the ADSs are purchased.

We have granted the underwriter an option to buy up to an additional            ADSs from us at the public offering price, less the underwriting discounts and commissions, to cover over-allotments, if any. The underwriter may exercise this option at any time, in whole or in part, during the 30-day period after the date of this prospectus.

Discounts, Commissions and Expenses

The underwriter proposes to offer to the ADSs purchased pursuant to the underwriting agreement to the public at the public offering price set forth on the cover page of this prospectus and to certain dealers at that price less a concession not in excess of $            per ADS. After this offering, the public offering price and concession may be changed by the underwriter. No such change shall change the amount of proceeds to be received by us as set forth on the cover page of this prospectus.

In connection with the sale of the ADSs to be purchased by the underwriter, the underwriter will be deemed to have received compensation in the form of underwriting commissions and discounts. The underwriting commissions and discounts will be            % of the gross proceeds of this offering, or $            per ADS, based on the public offering price per ADS set forth on the cover page of this prospectus.

We have also agreed to reimburse Roth Capital Partners at closing for expenses incurred by it in connection with the offering up to a maximum of $            .

The following table shows the underwriting discounts and commissions payable to the underwriter by us in connection with this offering (assuming both the exercise and non-exercise of the over-allotment option to purchase additional ADSs we have granted to the underwriter):

Indemnification

Pursuant to the underwriting agreement, we have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act, or to contribute to payments that the underwriter or such other indemnified parties may be required to make in respect of those liabilities.

Warrants

Upon the closing of this offering, we have agreed to sell to the underwriters a warrant to purchase up to 7.5% of the number of ordinary shares, represented by ADSs, sold in this offering. The warrant will be issued in three tranches, each comprising up to 2.5% of the number of shares of common stock sold in the offering, with the tranches exercisable at an exercise price equal to 120%, 135% and 150% of the public offering price per ADS sold pursuant to this offering, respectively, subject to standard anti-dilution adjustments for share splits and similar transactions. The warrant will be exercisable at any time, and from time to time, in whole or in part, during the period commencing 180 days from the commencement of sales in this offering, and expiring three years from the commencement of sales in this offering. The warrant is also exercisable on a cashless basis. The warrants have been deemed compensation by FINRA and are therefore subject to a 180-day lock-up pursuant to FINRA Rule 5110(e)(1). Except as permitted by Rule 5110(e)(1), the underwriter (or permitted assignees under the Rule) will not sell, transfer, assign, pledge, or hypothecate the warrants or the securities underlying the warrants, nor will any, of them engage in any hedging, short sale, derivative, put, or call transaction that would result in the effective economic disposition of the option or the underlying securities for a period of 180 days from the commencement of sales under this prospectus.

Lock-Up Agreements

We have agreed not to (i) offer, pledge, issue, sell, contract to sell, purchase, contract to purchase, lend or otherwise transfer or dispose of, directly or indirectly, any ADSs or any securities convertible into or exercisable or exchangeable for ADSs; (ii) enter into any swap or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of ADSs; or (iii) file any registration statement with the SEC relating to the offering of any ADSs or any securities convertible into or exercisable or exchangeable for ADSs, without the prior written consent of Roth Capital Partners for a period of 180 days following the date of this prospectus (the “Lock-up Period”). This consent may be given at any time without public notice. These restrictions on future issuances are subject to exceptions for (i) the issuance of ADSs sold in this offering, (ii) the issuance of ordinary shares or ADSs upon the exercise of options or warrants or the conversion of outstanding preferred stock or other outstanding convertible securities, or (iii) the issuance of employee stock options not exercisable during the Lock-Up Period.

In addition, each of our directors and executive officers has entered into a lock-up agreement with the underwriter. Under the lock-up agreements, the directors and executive officers may not, directly or indirectly, sell, offer to sell, contract to sell, or grant any option for the sale (including any short sale), grant any security interest in, pledge, hypothecate, hedge, establish an open “put equivalent position” (within the meaning of Rule 16a-1(h) under the Securities Exchange Act of 1934, as amended, or the Exchange Act), or otherwise dispose of, or enter into any transaction which is designed to or could be expected to result in the disposition of, any ADSs or securities convertible into or exchangeable for ADSs, or publicly announce any intention to do any of the foregoing, without the prior written consent of Roth Capital Partners, for a period of 180 days from the closing date of this offering. This consent may be given at any time without public notice. These restrictions on future dispositions by our directors and executive officers are subject to exceptions for (a) transfers (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth in the lock-up agreement, or (ii) to any trust for the direct or indirect benefit of the undersigned or the immediate family of the undersigned, provided that the trustee of the trust agrees to be bound in writing by the restrictions of the lock-up agreement, and provided further that any such transfer shall not involve a disposition for value; or (b) the acquisition or exercise of any stock option approved by shareholders or issued pursuant to any equity incentive plan of the Company, limited only to options or plans that are described in this prospectus and provided the lock-up agreement applies to any of the securities issued upon such exercise.

Electronic Distribution

This prospectus may be made available in electronic format on websites or through other online services maintained by the underwriter or by its affiliates. In those cases, prospective investors may view offering terms online and prospective investors may be allowed to place orders online. Other than this prospectus in electronic format, the information on the underwriter’s website or our website and any information contained in any other websites maintained by the underwriter or by us is not part of this prospectus or the registration statement of which this prospectus forms a part, has not been approved and/or endorsed by us or the underwriter in its capacity as underwriter, and should not be relied upon by investors.

Price Stabilization, Short Positions and Penalty Bids

In connection with the offering the underwriter may engage in stabilizing transactions, over-allotment transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Exchange Act:

•        Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

•        Over-allotment involves sales by the underwriter of ADSs in excess of the number of ADSs the underwriter is obligated to purchase, which creates a syndicate short position. The short position may be either a covered short position or a naked short position. In a covered short position, the number of ADSs over-allotted by the underwriter is not greater than the number of ADSs that they may purchase in the over-allotment option. In a naked short position, the number of ADSs involved is greater than the number of ADSs in the over-allotment option. The underwriter may close out any covered short position by either exercising their over-allotment option and/or purchasing ADSs in the open market.

•        Syndicate covering transactions involve purchases of the ADSs in the open market after the distribution has been completed in order to cover syndicate short positions. In determining the source of ADSs to close out the short position, the underwriter will consider, among other things, the price of ADSs available for purchase in the open market as compared to the price at which they may purchase ADSs through the over-allotment option. A naked short position occurs if the underwriter sells more ADSs than could be covered by the over-allotment option. This position can only be closed out by buying ADSs in the open market. A naked short position is more likely to be created if the underwriter is concerned that there could be downward pressure on the price of the ADSs in the open market after pricing that could adversely affect investors who purchase in the offering.

•        Penalty bids permit the underwriter to reclaim a selling concession from a syndicate member when the ADSs originally sold by the syndicate member are purchased in a stabilizing or syndicate covering transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty bids may have the effect of raising or maintaining the market price of the ADSs or preventing or slowing a decline in the market price of the ADSs. As a result, the price of the ADSs may be higher than the price that might otherwise exist in the open market. These transactions may be discontinued at any time

Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the ADSs. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that any transaction, if commenced, will not be discontinued without notice.

Offer restrictions outside the United States

Other than in the United States, no action has been taken by us or the underwriter that would permit a public offering of the securities offered by this prospectus in any jurisdiction where action for that purpose is required. The securities offered by this prospectus may not be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this prospectus comes are advised to inform themselves about and to observe any restrictions relating to this offering and the distribution of this prospectus. This prospectus does not constitute an offer to sell or a solicitation of an offer to buy any securities offered by this prospectus in any jurisdiction in which such an offer or a solicitation is unlawful.

Notice to Prospective Investors in European Union

This prospectus has not been, and will not be, registered with or approved by any securities regulator in the European Union. Accordingly, this document may not be made available, nor may the ADSs be offered for sale, in the European Union except in circumstances that do not require a prospectus under Article 1(4) of Regulation (EU) 2017/1129 of the European Parliament and the Council of the European Union (the “Prospectus Regulation”).

In accordance with Article 1(4)(a) of the Prospectus Regulation, an offer of ADSs in the European Union is limited to persons who are “qualified investors” (as defined in Article 2(e) of the Prospectus Regulation).

Notice to Prospective Investors in the United Kingdom

Neither this prospectus nor any other document relating to the offer has been delivered for approval to the Financial Conduct Authority in the United Kingdom and no prospectus (within the meaning of section 85 of the Financial Services and Markets Act 2000, as amended (“FSMA”)) has been published or is intended to be published in respect of the ADSs.

The ADSs may not be offered or sold in the United Kingdom by means of this prospectus or any other document, except in circumstances that do not require the publication of a prospectus under section 86(1) of the FSMA. This prospectus is issued on a confidential basis in the United Kingdom to “qualified investors” within the meaning of Article 2(e) of the UK Prospectus Regulation. This prospectus may not be distributed or reproduced, in whole or in part, nor may its contents be disclosed by recipients, to any other person in the United Kingdom.

Each person in the UK who initially acquires any ADSs or to whom any offer is made will be deemed to have represented, acknowledged and agreed to and with the Company and the Underwriter that it is a qualified investor within the meaning of the UK Prospectus Regulation.

In the case of any ADSs being offered to a financial intermediary as that term is used in Article 5(1) of the UK Prospectus Regulation, each such financial intermediary will be deemed to have represented, acknowledged and agreed that the ADSs acquired by it in the offer have not been acquired on a non-discretionary basis on behalf of, nor have they been acquired with a view to their offer or resale to, persons in circumstances which may give rise to an offer to the public other than their offer or resale in the UK to qualified investors, in circumstances in which the prior consent of the representatives of the underwriters has been obtained to each such proposed offer or resale.
