VistaGen Announces FDA Authorization to Initiate Phase 2 Study of AV-101 for Major Depressive Disorder

SOUTH SAN FRANCISCO, CA--(Marketwired - October 26, 2017) - VistaGen Therapeutics Inc. (NASDAQ: VTGN), a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) disorders, announced today that the U.S. Food and Drug Administration (FDA) has authorized the Company to proceed, under its Investigational New Drug (IND) application, with its planned Phase 2 clinical study of AV-101 as a new generation oral treatment for major depressive disorder (MDD).

VistaGen is preparing to launch a 180-patient, multi-center, double-blind, placebo-controlled Phase 2 study to assess the safety, tolerability and efficacy of AV-101 as an orally administered adjunctive treatment for adult MDD patients with an inadequate response to standard, FDA-approved antidepressants. Dr. Maurizio Fava of Harvard Medical School will be the Principal Investigator of this study, expected to begin in the first quarter of 2018.

"This is a significant milestone in our AV-101 clinical development program," stated Shawn Singh, Chief Executive Officer of VistaGen. "With the FDA's authorization to proceed under our IND application now in hand, our primary goal remains to launch and complete our Phase 2 study of AV-101 for major depressive disorder in 2018, further advancing our efforts to develop and commercialize AV-101 as a new generation oral treatment alternative for depression, one with a mechanism of action that is fundamentally differentiated from all FDA-approved antidepressants and atypical antipsychotics often used adjunctively to augment them."

About AV-101

AV-101 (4-CI-KYN) is an oral CNS drug candidate in Phase 2 development in the U.S., initially as a new generation adjunctive treatment for MDD. AV-101 also has broad potential utility in several other CNS indications where modulation of NMDA receptors, activation of AMPA pathways and/or key active metabolites of AV-101 may achieve therapeutic benefit, including neuropathic pain and epilepsy, as well as addressing symptoms associated with neurodegenerative diseases, such as Parkinson's disease levodopa-induced dyskinesia (PD LID) and Huntington's disease.

AV-101 is currently being evaluated in a Phase 2 monotherapy study in MDD, a study being fully funded by the U.S. National Institute of Mental Health (NIMH) and conducted by Dr. Carlos Zarate Jr., Chief, Section on the Neurobiology and Treatment of Mood Disorders and Chief of Experimental Therapeutics and Pathophysiology Branch at the NIMH, as Principal Investigator.

About VistaGen

VistaGen Therapeutics, Inc. (NASDAQ: VTGN) is a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other CNS disorders. VistaGen's lead CNS product candidate, AV-101, is in Phase 2 development, initially as a new generation oral antidepressant drug candidate for MDD. AV-101's mechanism of action is fundamentally different from all FDA-approved antidepressants and atypical antipsychotics used adjunctively to treat MDD, with potential to drive a paradigm shift towards a new generation of safer and faster-acting antidepressants. AV-101 is currently being evaluated by the NIMH in a small Phase 2 monotherapy study in MDD being fully funded by the NIMH and conducted by Dr. Carlos Zarate Jr., Chief, Section on the Neurobiology and Treatment of Mood Disorders and Chief of Experimental Therapeutics and Pathophysiology Branch at the NIMH. VistaGen is preparing to launch a 180-patient Phase 2 study of AV-101 as an adjunctive treatment for MDD patients with an inadequate response to standard, FDA-approved antidepressants, with Dr. Maurizio Fava of Harvard University as Principal Investigator. AV-101 may also have the potential to treat multiple CNS disorders and neurodegenerative diseases in addition to MDD, including neuropathic pain, epilepsy, Huntington's disease, PD LID and other disorders where modulation of the NMDA receptors, activation of AMPA pathways and/or key active metabolites of AV-101 may achieve therapeutic benefit.
