Bionomics Initiates Phase 2b ATTUNE Study of BNC210 in PTSD
Bionomics Limited (ASX: BNO, OTCQB:BNOEF) has initiated the Phase 2b ATTUNE Study to assess the efficacy of its BNC210 tablet formulation in treating Post-Traumatic Stress Disorder (PTSD). The study will enroll around 200 patients across approximately 25 clinical sites in the U.S., with results expected by 1H 2023. BNC210, a first-in-class drug, has received Fast Track designation from the FDA due to the unmet need for PTSD treatments. The study aims to evaluate PTSD symptom severity improvements using a double-blind, placebo-controlled design.

ADELAIDE, Australia, July 6, 2021 /PRNewswire/ -- Bionomics Limited (ASX: BNO, OTCQB:BNOEF) (Bionomics or Company), a global, clinical stage biopharmaceutical company, is pleased to announce that it has initiated a Phase 2b trial (the ATTUNE Study) to evaluate the tablet formulation of BNC210 in patients with Post-Traumatic Stress Disorder (PTSD) with top line results expected in 1H 2023.
BNC210 is a novel, first-in-class, negative allosteric modulator of the a7 nicotinic acetylcholine receptor in development for the treatment of anxiety and stressor-related disorders and has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment of PTSD and other trauma- and stressor-related disorders, recognising the high unmet medical need in the treatment of such serious conditions.
The ATTUNE Study is a randomised, double-blind, placebo-controlled, multi-centre Phase 2b clinical trial with a 12-week treatment period. The primary objective is to compare BNC210 to placebo on the improvement in PTSD symptom severity as measured by the Clinician Administered PTSD scale for DSM-5 (CAPS-5) following 12 weeks of treatment. In addition to the clinician evaluation of PTSD symptom severity, there are a number of secondary objectives to measure patient-reported symptoms of PTSD, changes in anxiety and depression symptoms, and global and social functioning in the study participants. An oral tablet formulation of BNC210, showing much improved absorption over the previous liquid suspension formulation, will be evaluated in this study. The dose of BNC210 (900 mg twice daily) was selected based on achieving exposure levels that are predicted from a pharmacometric blood exposure-CAPS-5 response model, built on a previous BNC210 trial data set (RESTORE), as necessary to meet the primary endpoints for effectiveness for treating PTSD patients in clinical trials.
Premier Research, Global Contract Research Organisation (CRO) headquartered in the U.S., is contracted to manage the ATTUNE Study which will be conducted at around 25 clinical sites in the U.S., recruiting approximately 200 patients with PTSD. Premier Research is recognised as a leading CRO supporting industry-sponsored PTSD studies. Dr. Frank Weathers, author of the CAPS-5, is delivering a comprehensive training program to clinical site raters in the use of the CAPS-5 assessment scale ensuring collection of robust and reliable study data for the primary endpoint measure.
The trial protocol was submitted to the U.S. FDA at the end of May 2021 and on 22 June 2021 was granted ethics approval by a central human ethics Institutional Review Board (IRB). Clinical sites are activated and open to screen for potential study participants.
