SOUTH SAN FRANCISCO, CA / ACCESSWIRE / March 28, 2019 / VistaGen Therapeutics (NASDAQ: VTGN), a clinical-stage biopharmaceutical company developing new generation medicines for depression, social anxiety disorder and other central nervous system (CNS) diseases and disorders with high unmet need, today announced that the Australian Patent Office (IP Australia) has granted a patent related to methods of treating depression with AV-101, VistaGen’s oral drug candidate in Phase 2 development for treatment of major depressive disorder (MDD). The newly issued Australian Patent No. 2014209466 is a counterpart to U.S. Patent No. 9,993,453 granted to VistaGen by the U.S. Patent and Trademark Office in June 2018, and will not expire until at least 2034.

About AV-101

VistaGen’s AV-101 (4-Cl-KYN) is an investigational, oral NMDA receptor glycine site antagonist with potential to be a treatment for multiple CNS indications with high unmet need. AV-101 is currently in Phase 2 clinical development in the U.S. for MDD and in a first-step target engagement study in healthy volunteer U.S. military Veterans for suicidal ideation. The U.S. Food and Drug Administration (FDA) has granted Fast Track designation for development of AV-101 as both a potential adjunctive treatment for MDD and as a non-opioid treatment for neuropathic pain.

About Major Depressive Disorder (MDD)

According to the World Health Organization (WHO), MDD affects nearly 300 million people of all ages globally and is the leading cause of disability worldwide. Individuals with depression, including MDD, experience continuous suffering from the serious, biologically-based disease which has a significant negative impact on all aspects of life, including quality of life. While current antidepressants are widely used for treatment, large-scale studies have suggested that the drug-treated MDD market is substantially underserved by current medications.
