InvestorNewsBreaks – VistaGen Therapeutics Inc. (NASDAQ: VTGN) Announces Positive Results from PH80 Exploratory Phase 2A Study

Vistagen (NASDAQ: VTGN), a late clinical-stage biopharmaceutical company aiming to transform the treatment landscape for individuals living with anxiety, depression and other central nervous system (“CNS”) disorders, today announced that PH80, one of the company’s five investigational neuroactive nasal sprays, demonstrated statistically significant efficacy versus placebo in an exploratory phase 2A study. The randomized, double-blind, placebo-controlled study was designed to explore the efficacy, safety and tolerability of intranasal administration of PH80 for the acute management of menopausal hot flashes in women. “The previously unreported results of this exploratory phase 2A clinical study of PH80 for treatment of menopausal hot flashes are yet another part of the promising larger body of evidence regarding the potential of our innovative pherine nasal spray pipeline,” said Shawn Singh, chief executive officer of Vistagen. “There is clearly a need for an alternative treatment option for menopausal hot flashes that provides rapid relief without the safety, side effects and treatment burden of the currently available options. We are encouraged by the potential that PH80 holds to improve the treatment paradigm for hot flashes and reduce the serious physical burden on the quality of life experienced by millions of women worldwide.”

About VistaGen Therapeutics Inc.

Vistagen is a late clinical-stage biopharmaceutical company aiming 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 for treatment of anxiety, depression and multiple CNS disorders. Vistagen’s pipeline includes six clinical-stage product candidates, including five investigational agents belonging to a new class of drugs known as pherines, in addition to AV-101, an oral prodrug of 7-Cl-CYNA, which is a full antagonist of the glycine site of the N-methyl-D-aspartate receptor (“NMDAR”), inhibiting activity of the ion channel of the NMDAR but not blocking it. Pherines, which are administered as nasal sprays, are designed with an innovative rapid-onset mechanism of action that activates chemosensory neurons in the nasal passages and can selectively and beneficially impact key neural circuits in the brain without requiring systemic uptake or direct activity on CNS neurons. Vistagen is passionate about transforming mental health care and redefining what is possible in the treatment of anxiety, depression and several other CNS disorders.
