About
Vistagen is a late clinical-stage biopharmaceutical company headquartered in South San Francisco, CA, developing and commercializing a new class of intranasal product candidates called pherines. Leveraging advanced insights into nose-to-brain neurocircuitry, Vistagen designs pherines to selectively activate peripheral nasal chemosensory receptors and rapidly trigger olfactory bulb–to-brain pathways that influence behavior and autonomic nervous system activity. Because they are engineered to work without entering the bloodstream or brain, pherines have the potential to offer safer therapeutic alternatives to existing pharmacological treatments if successfully developed and approved.
