ADELAIDE, Australia and CAMBRIDGE, Mass., July 31, 2024 (GLOBE NEWSWIRE) -- Bionomics Limited (Nasdaq: BNOX) (Bionomics or Company), a clinical-stage biotechnology company developing novel, first-in-class, allosteric ion channel modulators to treat patients suffering from serious central nervous system (CNS) disorders with high unmet medical need, today announced the favorable outcomes of an EoP2 meeting with the FDA, supporting the advancement of its lead asset BNC210 for the treatment of PTSD into Phase 3 based on the positive results of the recently completed Phase 2b ATTUNE study.

“We are very pleased with the outcomes of our EoP2 meeting with the FDA and look forward to initiating our transformation into a pre-commercial organization,” said Spyros Papapetropoulos, M.D., Ph.D., President and CEO of Bionomics. “This milestone is another testament to the strong clinical profile of BNC210, which has demonstrated efficacy across multiple stress and anxiety disorders. We believe BNC210 can potentially transform the standard-of-care in PTSD, a serious disorder impacting about 7% of Americans during their lifetime. Followings the recent initiation of the Phase 3 trial of BNC210 in social anxiety disorder (AFFIRM-1), we look forward to starting a Phase 3 trial in PTSD by the end of 2024.”

The company presented the clinical plans to registration, that alongside the positive Phase 2b ATTUNE trial include a single additional Phase 3 trial to evaluate two dose levels of BNC210 in a 12-week randomized, double-blind, placebo-controlled trial with a 52-week open-label extension. The meeting, held on June 26, 2024, was centered around the design of the Phase 3 trial that if successful may enable review of the NDA submission. Key outcomes from the discussion on the trial design included:

1. Agreement was reached on the use of Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) as the primary endpoint measure and the Clinical Global Impressions Severity scale (CGI-S) as a key secondary endpoint measure in the placebo-controlled part of the study.
2. Agreement was reached that in addition to the efficacious dose of 900 mg twice daily (BID) a lower dose of BNC210 that strikes the right balance between maintenance of efficacy and safety related to liver function tests (LFT) findings will be tested. Full justification for the proposed lower dose of 600 mg twice daily (BID) will be included in the final Ph3 PTSD trial protocol.
3. High-level agreement was reached on study participant characteristics and sample size assumption methodology.
4. The company received guidance related to the proposed hepatic safety monitoring plan, including monitoring for excessive alcohol use that will be implemented in the planned Phase 3 trial.

The Company plans to submit the full Phase 3 protocol for FDA review prior to trial initiation.

The company is finalizing the full study protocol and anticipates beginning the Phase 3 program in PTSD in Q4 2024.

About Post Traumatic Stress Disorder

Post-Traumatic Stress Disorder (PTSD) is a psychiatric condition that may occur in people who have experienced or witnessed a traumatic event, series of events, or set of circumstances. People with PTSD have intense, disturbing thoughts and feelings related to their experience that persist long after the traumatic event has ended. They may relive the event through flashbacks or nightmares, may feel sadness, fear, or anger and may experience a sense of detachment or estrangement from others. As a result of these feelings, people with PTSD may avoid situations or people that remind them of the traumatic event, and they may have strong negative reactions to commonplace stimuli such as loud noises or an accidental touch.
