Veterans from Operation Enduring Freedom, Operation Iraqi Freedom and Operation New Dawn to Participate in Study

SOUTH SAN FRANCISCO, Calif. and HOUSTON, Aug. 13, 2018 (GLOBE NEWSWIRE) --  VistaGen Therapeutics, Inc. (NASDAQ:VTGN), a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) diseases and disorders, and Baylor College of Medicine (Baylor), today announced that VistaGen and Baylor are collaborating on a first-step study with healthy volunteer Veterans to test potential anti-suicidal effects of VistaGen's AV-101.

A total of 12 healthy volunteer Veterans from either Operation Enduring Freedom, Operation Iraqi Freedom or Operation New Dawn will be administered single doses of AV-101, at 720 mg and 1440 mg and placebo, over three weeks in a randomized, double-blind, cross-over study to define a dose-response relationship between AV-101 and relevant biomarkers related to NMDA function and others possibly related to suicidality. Dr. Marijn Lijffijt of Baylor will be Principal Investigator. VistaGen and the U.S. Department of Veterans Affairs (VA) entered into a Material Transfer Cooperative Research and Development Agreement (MT CRADA) regarding clinical trial material for this study, and government funding will be provided for substantially all other study costs.

"The number of Veterans who take their own life is tragic and staggering, averaging 20 suicides per day," said Shawn Singh, Chief Executive Officer of VistaGen. "These statistics are not acceptable. As suicide prevention is a vital mission of Baylor and VistaGen, our goal for this initial study is to set the stage to advance our collective efforts to help Veterans fight suicidal ideation on a long-term basis. Suicide is a national public health concern that affects people everywhere, and we must do more to raise awareness and pursue novel faster-acting and safe treatments to help those who continue to suffer from both debilitating depression and suicidal ideation. The status quo for treatment is just not working, and individuals, especially Veterans, need better alternatives."

"Baylor College of Medicine and Dr. Sanjay Mathew, a member of VistaGen's CNS Clinical and Regulatory Advisory Board, share an important mission to find better treatment alternatives for Veterans who suffer from depression, suicidal ideation and other CNS indications," added Dr. Lijffijt. "The suicide rate is two times higher in Veterans than in citizens of equivalent age and gender. A priority for suicide prevention is to come up with novel treatment targets for safe and rapidly acting interventions to impact acute suicidality, which is not adequately addressed with current treatments. This study is the first step in working to revolutionize the way that we treat suicidal ideation and behaviors. Our expectation is to complete the dosing by the end of September 2018, with top-line results from the study expected by year end. The results of this initial study in healthy volunteer Veterans could lead to a Phase 2 study involving AV-101 and Veterans who are battling suicidal ideation or behaviors."

AV-101 is currently undergoing two separate, more advanced Phase 2 clinical studies for the treatment of major depressive disorder.

About Suicide
According to the World Health Organization (WHO), every year approximately 800,000 people worldwide take their own life and many more attempt suicide.1 Suicide is a major public health concern in the United States as rates of suicide have been increasing for both men and women and across all age groups. Suicide is the 10th leading cause of death in the U.S. and is one of just three leading causes that are on the rise.2 The Center for Disease Control and Prevention (CDC) reported that in the U.S. the age-adjusted rate of suicide increased by 24 percent between 1999 and 2014.3 The number of U.S. citizens who die by suicide is, since 2010, higher than those who die in motor vehicle accidents. People of all genders, ages, and ethnicities can be at risk for suicide and suicidal behavior is complex and there is no single cause. In fact, many different factors contribute to someone making a suicide attempt, including, but not limited to, depression, other mental health disorders or substance abuse disorder; certain other medical conditions; chronic pain; prior suicide attempt; and family history of mental disorder or substance abuse.4  Additionally, it has been found that the Veteran population is at significantly higher risk for suicide. After adjusting for differences in age, risk for suicide was 19 percent higher among male Veterans compared with U.S. civilian adult men and 2.5 times higher among female Veterans compared with U.S. civilian adult women.5 Despite these many risk factors, suicide is not inevitable for those that have one or more risk factor(s). Starting a conversation, reducing stigma, providing support and resources and working to develop safe and novel treatments for those in need can help prevent suicide and save the lives of many.

Veterans who are in crisis or having thoughts of suicide, and those who know a Veteran in crisis, should call the Veterans Crisis Line for confidential support 24 hours a day, seven days a week, 365 days a year at 800-273-8255 and press 1, chat online at VeteransCrisisLine.net/Chat or send a text message to 838255.

About AV-101
AV-101 is an oral, non-opioid, non-sedating NMDA receptor glycine B (NMDAR GlyB) antagonist that offers the potential to be a new at-home treatment for multiple CNS indications with high unmet medical need. AV-101 is currently in Phase 2 clinical development in the United States for treatment of major depressive disorder. ELEVATE is VistaGen's ongoing Phase 2 clinical trial designed to evaluate the efficacy and safety of adjunctive use of AV-101 for MDD in patients with an inadequate response to standard antidepressant therapy with either an FDA-approved selective serotonin reuptake inhibitor (SSRI) or serotonin norepinephrine reuptake inhibitor (SNRI). AV-101's mechanism of action (MOA) is fundamentally different from that of all current FDA-approved SSRIs and SNRIs, most of which, if effective for a given patient, take many weeks to achieve therapeutic benefits.

AV-101 may also have the potential to treat neuropathic pain, epilepsy, Parkinson's disease levodopa-induced dyskinesia, suicidal ideation and other CNS diseases and disorders where NMDA receptor modulation and AMPA pathway activation may achieve therapeutic benefits. The FDA has granted Fast Track designation to AV-101 for development as a potential adjunctive treatment of MDD.
