Vistagen (NASDAQ: VTGN) is a clinical-stage biopharmaceutical company aiming to transform the treatment landscape for individuals living with anxiety, depression and other central nervous system (“CNS”) disorders. Together with Fuji Pharma Co. (TSE: 4554), a pharmaceutical company specializing in development, manufacture and marketing in the fields of women’s health care and acute medical care, the companies announced their entry into a time-limited (up to approximately eighteen months) agreement to negotiate exclusively regarding a potential license to develop and commercialize Vistagen’s PH80 in Japan, including for the acute treatment of moderate to severe vasomotor symptoms (hot flashes) due to menopause and potentially other indications. “As we have seen across our neuroactive pherine nasal spray pipeline, PH80 offers exciting potential to transform a significant segment of a major health care market, including the current treatment landscape for women’s health care,” said Shawn Singh, CEO of Vistagen. “Menopausal hot flashes affect millions of women worldwide. We share Fuji Pharma’s long-standing commitment to deliver innovative treatment options with potential to enable women to improve their physical, mental and social well-being. As we continue to advance our PH80 development program in the U.S., we look forward to continuing our ongoing discussions with Fuji regarding a potential development and commercialization collaboration in Japan.”

About VistaGen Therapeutics Inc.

Vistagen is a clinical-stage biopharmaceutical company aiming to transform the treatment landscape for individuals living with anxiety, depression and other CNS disorders. Vistagen is advancing therapeutics with the potential to be faster-acting, and with fewer side effects and safety concerns, than those currently available for the treatment of anxiety, depression and multiple CNS disorders. Vistagen’s pipeline includes six clinical-stage product candidates, including fasedienol (“PH94B”), itruvone (“PH10”), “PH15,” “PH80,” and “PH284,” with each of these being an investigational agent belonging to a new class of drugs known as pherines, as well as “AV-101,” which is an oral prodrug of an antagonist of the N-methyl-D-aspartate receptor (“NMDAR”). Pherines are neuroactive nasal sprays designed with an innovative proposed mechanism of action that activates chemosensory neurons in the nasal cavity and can beneficially impact key neural circuits in the brain without systemic absorption or direct activity on neurons in the brain. Vistagen is passionate about transforming mental health care and redefining what is possible in the treatment of anxiety, depression and several other CNS disorders.
