VistaGen says fasedienol misses primary endpoint in PALISADE-4 Phase 3 social anxiety trial

• VistaGen reported topline results from the PALISADE-4 Phase 3 trial of intranasal fasedienol for acute social anxiety during a public-speaking challenge.
• The study missed its main goal in the overall patient group, with no clear benefit versus placebo on key measured outcomes.
• A post-hoc analysis suggested an efficacy signal in patients with very severe social anxiety, supporting continued development despite the primary miss.
• Strategy shifts toward a registrational path for longer-term treatment, targeting a future multi-dose Phase 3 trial using a standard social-anxiety severity scale.
• Safety and tolerability remained consistent with prior placebo-controlled studies, reducing downside risk to the program’s risk-benefit profile.
