Vistagen Therapeutics Inc Dossier
Qualitative Analysis
Business overview
Vistagen Therapeutics, Inc. (Nasdaq: VTGN) is a late clinical-stage biopharmaceutical company pioneering neuroscience with nose-to-brain neurocircuitry to develop and commercialize a new class of rapid-onset, non-systemic intranasal product candidates called pherines. The company's pipeline is designed to address psychiatric and neurological disorders without the systemic absorption, cognitive impairment, or sexual side effects typical of traditional therapies. Its lead candidate is fasedienol, an investigational pherine nasal spray in Phase 3 development for the acute treatment of social anxiety disorder (SAD). Other pipeline assets include itruvone for major depressive disorder (MDD) and refisolone for vasomotor symptoms (hot flashes) due to menopause.
