## What Vistagen Therapeutics does

Vistagen Therapeutics, Inc. is a late clinical-stage therapeutics company developing and potentially commercializing medicines for social anxiety disorder, depression, menopausal hot flashes, psychomotor impairment due to mental fatigue and cancer cachexia. Its neuroscience pipeline consists of five clinical-stage intranasal pherine product candidates, each designed to bind peripheral receptors in human nasal chemosensory neurons and activate neurocircuits without requiring systemic absorption or uptake into the brain. The most advanced candidate, fasedienol, is in a U.S. Phase 3 PALISADE program for the acute treatment of social anxiety disorder and has fast track designation from the FDA for that indication. Neither PALISADE-1 nor PALISADE-3 achieved its primary endpoint in the randomized phase, while PALISADE-2 achieved its primary efficacy endpoint in August 2023. Topline results from the randomized portion of PALISADE-4 are expected in the second quarter of calendar 2026. The other candidates are itruvone for major depressive disorder, refisolone for moderate to severe vasomotor symptoms due to menopause, PH15 for psychomotor impairment due to mental fatigue, and PH284 for cancer cachexia.

| Product or program | What it is | Stage |
|---|---|---|
| Fasedienol | Intranasal pherine for acute treatment of social anxiety disorder | U.S. Phase 3 |
| Itruvone | Intranasal pherine for major depressive disorder |  |
| Refisolone | Intranasal pherine for moderate to severe menopausal hot flashes |  |
| PH15 | Intranasal pherine for psychomotor impairment due to mental fatigue |  |
| PH284 | Intranasal pherine for cancer cachexia |  |
