About Vistagen Vistagen (Nasdaq: VTGN) is a late clinical-stage biopharmaceutical company leveraging a deep understanding of nose-to-brain neurocircuitry to develop and commercialize a new class of rapid-onset neurocircuitry-focused intranasal product candidates called pherines. Vistagen’s pherine product candidates are designed to achieve therapeutic benefits without requiring absorption into the blood or uptake into the brain, giving them the potential to be a safer alternative to other pharmacological options, if successfully developed and approved. Vistagen’s most advanced intranasal pherine product candidates are fasedienol in U.S. Phase 3 development for social anxiety disorder and, in Phase 2 development, itruvone for major depressive disorder and refisolone for vasomotor symptoms (hot flashes) due to menopause.
