[{"type":"text","content":"\nPH80 patent portfolio now includes U.S. patents for treatment of both hot flashes and migraine\n\n SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--\nVistagen (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 the U.S. Patent and Trademark Office (USPTO) has granted a U.S. patent for Vistagen’s PH80 nasal spray for treatment of migraine.
