MELBOURNE, Australia and NEW YORK, Jan. 18, 2024 (GLOBE NEWSWIRE) -- Incannex Healthcare Inc. (NASDAQ:IXHL), (‘Incannex' or the ‘Company'), a pharmaceutical company developing unique medicinal cannabinoid pharmacotherapies and psychedelic medicine therapies is pleased to announce that it has completed dosing and treatment protocols for all 72 participants in the PsiGAD-1 clinical trial, the Company's Phase 2 study evaluating its own psilocybin treatment program for patients with generalized anxiety disorder (GAD).

PsiGAD-1 is a randomised triple-blind active-placebo-controlled Phase 2 trial. The primary objective of the study is to determine whether a 7-week program of psilocybin-assisted psychotherapy for GAD is superior to active placebo-assisted psychotherapy in decreasing symptoms of GAD, as measured by the change in the Hamilton Anxiety Rating Scale (HAM-A) from baseline to week 11. Safety and tolerability were assessed, as well as other secondary objectives of efficacy and quality of life.

"We're delighted to have completed all PsiGAD-1 treatments for our trial participants as we work towards finalising an FDA IND application to advance the development of this important treatment modality," said Joel Latham, Chief Executive Officer and Director of Incannex. "Generalised anxiety disorder is characterised by persistent, debilitating and excessive worry, affects millions of people globally, and has inadequate existing treatment options. We're thankful to our research partners at Monash University who conducted a thorough and extensive clinical trial, screening 975 people and undertaking 174 psychedelic dosing sessions in one of the largest clinical trials of its kind."

FDA IND Application Preparations for PsiGAD

Incannex commenced the process of drafting an FDA IND application in August 2023 in preparation of the receipt of topline results from the PsiGAD-1 clinical trial, and submission soon thereafter.

In March of 2023, Incannex announced the interim analysis for the Phase 2 PsiGAD-1 clinical trial, which predicted a greater than 85% chance that the trial would show statically significant benefit for the psilocybin treatment arm versus the placebo arm at the conclusion of the trial period. An independent Data Safety Monitoring Board (DSMB) was tasked with confidentially reviewing the data for the first 37 out of 72 trial participants. At that time, the DSMB recommended no adjustments to the original study design or sample size and acknowledged no safety concerns in the operation of the trial.

Documentary on the Monash Clinical Psychedelic Lab to be released in Late February 2024

Commissioned by the Australian Special Broadcasting Service (SBS), a film production company has tracked the activities of the Monash Clinical Psychedelic Lab for over 2 years, producing a documentary that focuses on the PsiGAD research program. Psychedelics: Stepping into the Unknown is a feature documentary on the first psychedelic lab in Australia and key partner in Incannex's psychedelic research program. The documentary is currently scheduled for release on the SBS streaming service in late February 2024, and aims to contribute to the awareness of mental health, psychedelic therapies, and the expertise required for safe delivery.
