VistaGen Therapeutics Receives Notices of Allowance in Australia and Japan for AV-101 Patents Covering Treatment of Depression

SOUTH SAN FRANCISCO, Calif., Nov. 12, 2018 (GLOBE NEWSWIRE) -- VistaGen Therapeutics (NASDAQ: VTGN), a clinical-stage biopharmaceutical company developing new generation medicines for central nervous system (CNS) diseases and disorders with high unmet need, today announced receiving Notices of Allowance  from IP Australia and the Japan Patent Office (JPO) related to methods of treating depression with AV-101, VistaGen’s oral NMDA (N-methyl-D-aspartate) receptor glycine B antagonist in Phase 2 development for adjunctive treatment of major depressive disorder (MDD).

“These patents, when issued, will extend our commercial protection of AV-101 into Australia and Japan, two additional major pharmaceutical markets,” stated Shawn Singh, Chief Executive Officer of VistaGen. “As we continue to move forward with our clinical development of AV-101 for adjunctive treatment of MDD, having important AV-101 intellectual property outside of the U.S. and Europe is essential for potential strategic partnering opportunities in selected regional markets and to support our mission to bring new treatment alternatives for CNS conditions with unmet need to individuals around the world."
