-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 the Company has taken important strategic steps to secure additional patent protection for its lead product candidate, PH94B, through the recent filing of national applications at the U.S. Patent and Trademark Office (USPTO) and counterpart patent authorities in major pharmaceutical markets outside the U.S. for the treatment of adjustment disorder (AjD).
These new filings are intended to provide a global exclusivity platform for PH94B in AjD, similar to the Company’s patent protection for PH94B for the treatment of social anxiety disorder (SAD), and for its other late-clinical stage product candidate, PH10, for the treatment of major depressive disorder (MDD).
Vistagen recently announced its pending acquisition of Pherin Pharmaceuticals, Inc. Upon closing of the acquisition, which is subject to certain customary closing conditions, Vistagen will acquire Pherin’s entire pherine pipeline, resulting in Vistagen gaining full ownership of intellectual property rights to PH94B, which is currently in Phase 3 development for SAD and Phase 2 development for AjD with anxiety (AjDA), and PH10, which is in clinical development for MDD. Vistagen will also gain full ownership of three new early clinical-stage pherine product candidates: PH15 for cognition improvement; PH284 for appetite-related disorders and PH80 for migraine and hot flashes. When the acquisition is completed, Vistagen's global patent portfolio for novel pherine class compounds will further expand to include U.S. and foreign counterpart patent applications related to the use of PH80 for the treatment of migraine and for the treatment of hot flashes.
