VistaGen to Present Preclinical Data on Lead Candidate PH94B at Upcoming Scientific Congresses
Research presented at the Annual Meeting of the Society of Biological Psychiatry and of the American Society of Clinical Psychopharmacology highlight fundamentally differentiated mechanism of action for PH94B
These preclinical data demonstrate that intranasal radiolabelled-PH94B is largely confined to the nasal passages where it stimulates chemosensory neurons located in the nasal epithelium. The localized effect within the nasal epithelium may explain why PH94B’s anxiolytic properties in humans do not require systemic uptake or transport into the brain.
SOUTH SAN FRANCISCO, Calif., April 21, 2022 —VistaGen Therapeutics, Inc. (Nasdaq: VTGN) (VistaGen) a late clinical-stage, central nervous system (CNS) focused biopharmaceutical company aiming to transform the treatment landscape for individuals living with anxiety, depression and other CNS disorders, announced that researchers will present preclinical data supporting the differentiated mechanism of action (MOA) for VistaGen’s lead product candidate, PH94B, at two upcoming major scientific congresses. VistaGen is currently evaluating PH94B in multiple Phase 3 trials for the acute treatment of anxiety in adults with social anxiety disorder (SAD).
Louis Monti, M.D., Ph.D., VistaGen’s Vice President of Translational Medicine, will present the data based on the study, Brain and Peripheral Distribution of Intranasal Radiolabeled PH94B in Laboratory Rats as follows:
|

As a late-breaking poster presentation on April 30 from 3:00 p.m. to 5:00 p.m. Pacific Time at the Annual Meeting of the Society of Biological Psychiatry (SOBP), occurring on April 28 – April 30, 2022, in New Orleans, Louisiana; and |
|
● |
As a poster at the Annual Meeting of the American Society of Clinical Psychopharmacology (ASCP), occurring May 31 – June 03, 2022, in Scottsdale, Arizona. |
Late last year, VistaGen released preclinical data that further support that the proposed MOA of PH94B involves binding to receptors of peripheral neurons in the nasal passages, rather than neuronal receptors in the CNS. These data suggest that anxiolytic activity can be achieved without systemic exposure or transport into the brain, resulting in a lower risk for side effects.
“VistaGen is committed to transforming the existing standards of treatments for anxiety and depression disorders,” said Shawn Singh, Chief Executive Officer of VistaGen. “As these preclinical data demonstrate, the proposed mechanism of action of our Phase 3 clinical candidate, PH94B, is fundamentally unique from all currently available anti-anxiety therapies. In the pandemic years alone, mental health crisis incidents have tripled, making it clear that patients need options that are faster, safer, and more tolerable than the current products on the market. Our ongoing PALISADE Phase 3 Program for SAD is designed to assess PH94B’s potential to address that need.”
About PH94B
VistaGen’s PH94B is a first-in-class, rapid-onset (approximately 15 minutes) pherine nasal spray being evaluated for the acute treatment of SAD in adults. Pherines are odorless, synthetic neuroactive steroids that bind to distinct receptors on chemosensory cells in the nasal passages and can impact the limbic amygdala without systemic uptake. Designed to be administered intranasally at microgram doses, the unique potential MOA of PH94B is fundamentally differentiated from all current anti-anxiety medications, including benzodiazepines. PH94B’s proposed MOA does not involve either direct activation of GABA-A receptors or binding to neuronal receptors in the CNS. Rather, PH94B’s proposed MOA involves binding to peripheral neurons in the nasal passages, with very limited systemic exposure. Taken together, these data suggest that PH94B has the potential to achieve rapid-onset anti-anxiety effects without systemic uptake or transport into the brain, reducing the risk of benzodiazepine-like side effects and other safety concerns. VistaGen is currently evaluating PH94B in two Phase 3 clinical studies in the U.S., PALISADE-1 and PALISADE-2, and a long-term safety study, for the acute treatment of anxiety in adults with SAD. The FDA has granted Fast Track designation for the development of PH94B as a potential treatment for SAD.
About VistaGen
VistaGen (Nasdaq: VTGN) is a late clinical-stage, CNS-focused biopharmaceutical company striving to transform the treatment landscape for individuals living with anxiety, depression and other CNS disorders. The Company is advancing therapeutics with the potential to be faster-acting, and with fewer side effects and safety concerns, than those that are currently available. VistaGen’s clinical-stage candidates are targeting multiple forms of anxiety and depression. They belong to a new class of drugs known as pherines, which are odorless, neuroactive steroids that bind to distinct receptors on chemosensory neurons in the nasal passages and can impact the limbic amygdala without systemic uptake or direct activity on CNS neurons in the brain. VistaGen’s lead candidate, PH94B, is a nasally administered spray currently in multiple Phase 3 trials in the U.S., with results anticipated in 2022. Should ongoing Phase 3 studies be successful, PH94B has the potential to be the first FDA-approved, fast-acting, acute treatment of anxiety for adults with social anxiety disorder. With an experienced leadership team and a steady flow of near- and long-term potential milestones, VistaGen is passionate about transforming mental health care and redefining what is possible in the treatment of anxiety and depression.
