Clinical Trial Summary

This U.S. Phase 3 clinical trial is designed to evaluate the efficacy, safety, and tolerability of the acute intranasal (i.n.) administration of Fasedienol Nasal Spray (fasedienol) (3.2 µg) to relieve symptoms of acute anxiety in adult subjects ages 18 through 65 with Social Anxiety Disorder induced by a public speaking challenge (PSC) in a clinical setting. In addition, safety and tolerability of i.n. administration of 3.2 µg of fasedienol, as-needed, up to 6 times per day for up to 12 months, will be assessed in those subjects who complete PALISADE-3 and choose to enter the distinct open-label extension phase of the study.
