8-K: Incannex Healthcare Receives FDA Approval to Proceed with Phase 2 Trial for Psilocybin-Assisted Anxiety Therapy

Incannex Healthcare has received FDA approval to begin a Phase 2 clinical trial for its psilocybin-assisted psychotherapy treatment for generalized anxiety disorder.

Summary

• Incannex Healthcare has received FDA approval to proceed with its Phase 2 clinical trial, PsiGAD2, for psilocybin-assisted psychotherapy in patients with generalized anxiety disorder.
• The trial will investigate Incannex's psilocybin formulation, PSX-001, in conjunction with psychotherapy.
• The study will recruit approximately 94 patients in the US and UK, including those currently on SSRIs.
• Patients will receive two doses of PSX-001 under double-blind conditions, along with preparatory and integration psychotherapy sessions.
• The primary endpoint is the change in Hamilton Anxiety Rating Scale (HAM-A) score two weeks after the second dosing session.
• Secondary endpoints include changes in HAM-A scores over 23 weeks, quality of life, healthcare utilization, EEG, and safety and tolerability.
• The PsiGAD2 trial builds on the positive results of the PsiGAD1 trial, which showed a 12.8 point reduction in HAM-A score in the psilocybin treatment group compared to placebo.
• In the PsiGAD1 trial, 44% of patients in the psilocybin group had a greater than 50% reduction in HAM-A score, and 27% achieved disease remission.
• The PsiGAD2 trial is also under review by the Medicines and Healthcare Products Regulatory Agency (MHRA) in the UK.

Comparison to Industry Standards
