SOUTH SAN FRANCISCO, Calif., Sept. 24, 2026 (GLOBE NEWSWIRE) -- Vistagen (NASDAQ:VTGN), a late clinical-stage biopharmaceutical company leveraging nose-to-brain neurocircuitry to develop and commercialize a new class of intranasal product candidates called pherines, presented positive exploratory data at Psych Congress 2026 in New Orleans. The poster highlights a potential efficacy signal for fasedienol nasal spray, the Company's rapid-onset Phase 3 product candidate, observed in a public speaking challenge study involving participants with very severe social anxiety disorder.

The research presented by Vistagen in a poster supports fasedienol’s potential for individuals with very severe social anxiety disorder, as defined by a baseline Liebowitz Social Anxiety Scale (LSAS) score of 95 or higher. In subpopulation analyses, one post-hoc and one prespecified, from two randomized, double-blind, placebo-controlled clinical trials, participants with very severe (LSAS >=95) social anxiety disorder experienced improvements in anxiety symptoms following treatment with fasedienol compared with placebo as measured by the Subjective Units of Distress Scale (SUDS).
