VistaGen Therapeutics (NASDAQ: VTGN), a clinical-stage biopharmaceutical company developing new generation medicines for depression, social anxiety disorder and other central nervous system (CNS) diseases and disorders with high unmet need, announced today additional results from a positive pilot Phase 3 study of PH94B, a potential first-in-class neuroactive nasal spray shown to be effective on an as-needed (PRN) basis for treatment of social anxiety disorder (SAD). The new data were presented in a poster session at the 2019 Anxiety and Depression Association of America (ADAA) Annual Conference in Chicago.

About PH94B Neuroactive Nasal Spray: PH94B neuroactive nasal spray is fundamentally different from all current treatments for SAD. Developed from proprietary compounds called pherines and administered as a nasal spray, PH94B activates nasal chemosensory receptors that trigger neural circuits in the brain that suppress fear and anxiety. Its novel mechanism of pharmacological action, rapid-onset of therapeutic effects and exceptional safety and tolerability profile shown in clinical trials to date make PH94B neuroactive nasal spray an excellent product candidate with potential to become the first FDA-approved PRN treatment for SAD.

In a published double-blind, placebo-controlled Phase 2 clinical trial, PH94B neuroactive nasal spray was significantly more effective than placebo in reducing public-speaking and social interaction anxiety on laboratory challenges of individuals with SAD.2.
