[{"type":"text","content":" SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--\nVistagen (Nasdaq: VTGN), a clinical-stage neuroscience-focused biopharmaceutical company dedicated to the development and commercialization of groundbreaking therapies for psychiatric and neurological disorders based on nose-to-brain neurocircuitry, today announced the broadening of its global intellectual property portfolio after receiving multiple new patents related to the use of PH80 for the treatment of migraine. PH80 is a non-systemic, hormone-free investigational pherine nasal spray in development as a rapid-onset treatment for vasomotor symptoms (hot flashes) due to menopause, with the potential to also treat premenstrual dysphoric disorder, dysmenorrhea, and migraine.\n\n\nThe new patents complement previously granted PH80 U.S. Patent No. 11,419,881 and EPO Patent No. 3955933 for the treatment of migraine. All of the new patents are expected to be in effect until 2040, subject to possible patent term extensions on a country-by-country basis.\n\n\n\nAustralia: IP Australia issued a Notice of Allowance;\n\n\n\nHong Kong: The Hong Kong Special Administrative Region – Intellectual Property Department issued Patent No. 40068177;\n\n\n\nJapan: The Japan Patent Office issued Patent No. 7476229; and\n\n\n\nMexico: The Mexican Institute of Industrial Property issued a Notice of Allowance.\n\n\n\nAbout PH80 Nasal Spray\n\n\nPH80 is an investigational neuroactive pherine nasal spray with a novel neurocircuitry-focused mechanism of action (MOA) that is fundamentally differentiated from all currently approved treatment options for women’s health indications. PH80’s proposed MOA does not require systemic absorption or direct activity on neurons in the brain. Vistagen is developing PH80 as a potential new hormone-free treatment for the management of vasomotor symptoms (hot flashes) due to menopause, with additional potential in premenstrual dysphoric disorder, migraine, and dysmenorrhea.\n\n\nAbout Pherines\n\n\nPherines are a novel class of synthetic neurocircuitry-focused drug candidates for psychiatric and neurological disorders. They are odorless and tasteless neuroactive steroids, delivered only intranasally, each with a differentiated mechanism of action (MOA) and safety profile from all currently approved drugs. Our neuroactive pherines rapidly activate olfactory system neurocirc...
