BURLINGTON, Mass., Sept. 04, 2025 (GLOBE NEWSWIRE) -- Neuphoria Therapeutics Inc. (NASDAQ:NEUP) ("Neuphoria" or the "Company"), a clinical-stage biotechnology company developing impactful treatments for neuropsychiatric disorders, today announced the achievement of target enrollment of 332 participants in the AFFIRM-1 Phase 3 trial evaluating lead candidate BNC-210 as a first-in-class, acute, "as needed", fast-acting treatment for social anxiety disorder (SAD).

"We are thrilled to reach our target enrollment in the AFFIRM-1 trial evaluating BNC-210 as a transformative therapeutic for the treatment of SAD," said Spyros Papapetropoulos, M.D., Ph.D., President and CEO of Neuphoria. "Achieving this milestone puts us on a clear path toward our first Phase 3 data for BNC-210, now expected early in the fourth quarter."

About BNC-210

BNC-210 is an oral, proprietary, selective negative allosteric modulator of the α7 nicotinic acetylcholine receptor under development for the treatment of SAD and post-traumatic stress disorder (PTSD). BNC-210 has been given FDA Fast Track designation for acute treatment of SAD and other anxiety related disorders, and for treatment of PTSD and other trauma and stressor related disorders. BNC-210 has demonstrated rapid-onset, broad and meaningful anti-anxiety effects in completed clinical trials in SAD, generalized anxiety disorder (GAD) and panic attacks without evidence of sedation, impairments in cognition or addiction potential.

About AFFIRM-1

The AFFIRM-1 Phase 3 clinical trial is a multi-center, double-blind, two-arm, parallel group, placebo-controlled trial evaluating the safety and efficacy of a single, acute dose of 225 mg of BNC-210 versus placebo. Participants in the trial are randomized 1:1 to receive a single dose of 225 mg BNC-210 or matched placebo. Approximately one hour after dosing, participants are introduced to a public speaking challenge and have two minutes to prepare for the speech (anticipation phase) before delivering a five-minute speech in front of a small audience (performance phase). The primary endpoint of the trial is the change from baseline to the average of the performance phase of the public speaking challenge in Subjective Units of Distress Scale (SUDS) scores. Secondary endpoints include change in SUDS score from baseline to the average of the anticipation phase, changes in the Clinical Global Impression – Severity (CGI-S) scale, and self-assessment with the State Trait Anxiety Inventory (STAI-State) and the Patient Global Impression – Improvement (PGI-I) scale. A follow-up visit occurs one week after the public speaking challenge.

About Social Anxiety Disorder

SAD is a significant and persistent fear of social and performance-related situations. As one of the most common mental disorders in the United States, an estimated 31 million Americans will suffer from SAD at some point in their lives. SAD can interfere with a person's ability to work, make it difficult to maintain friendships, family relationships, and romantic partnerships, cause a person to avoid lifestyle activities like dining out and traveling, and make normal parts of everyday life such as grocery shopping, calling a handyman, or picking up coffee challenging.
