VistaGen Therapeutics Appoints Dr. Michael Liebowitz to CNS Clinical and Regulatory Advisory Board in Preparation for Pivotal Phase 3 Development of PH94B as the First Rapid-Acting, On-Demand Treatment of Social Anxiety Disorder

SOUTH SAN FRANCISCO, Calif., Oct. 15, 2018 (GLOBE NEWSWIRE) -- VistaGen Therapeutics Inc (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 the appointment of Michael Liebowitz, M.D. to the Company’s CNS Clinical and Regulatory Advisory Board in preparation for pivotal Phase 3 development of PH94B as the first rapid-acting, on-demand treatment for social anxiety disorder (SAD), a debilitating social phobia which affects as many as 15 million American adults.

“We are extremely pleased to be working with Dr. Liebowitz to prepare for and advance PH94B through our pivotal Phase 3 program for SAD. He is a pioneer and internationally recognized leader in the field of anxiety disorders who will continue to shape and inform the future of these therapies in his role as a member of our CNS Clinical and Regulatory Advisory Board,” said Mark Smith, M.D., Ph.D., Chief Medical Officer of VistaGen. “Dr. Liebowitz has done life-changing work in addressing the widespread affliction of SAD. He has not only conducted many clinical trials in SAD, but he also developed the Liebowitz Social Anxiety Scale, or LSAS, which is widely-used as a primary outcome measure in clinical research on SAD, as well as for evaluation in clinical practice. Most importantly, we share his passion in helping patients. His decades of expertise will add enormous value to our efforts to provide a new and more effective treatment to the millions of people who are suffering from this debilitating condition.”

Dr. Liebowitz is a Columbia University psychiatrist and former director and founder of the Anxiety Disorders Clinic at the New York State Psychiatric Institute. He retired in 2006 as Director of the Anxiety Disorder Clinic, a position that he held since 1982, and is a member of the American Society of Clinical Psychopharmacology, Anxiety Disorder Association of America Scientific Advisory Board, American College of Neuropsychopharmacology and American Psychiatric Association. He is also Managing Director of The Medical Research Network LLC and serves on the editorial board of Depression and Anxiety. Dr. Liebowitz has published numerous journal articles, books and chapters about psychiatry.

“Due to the predictable occurrence of various performance and social situations that individuals with SAD fear and avoid, an effective, rapidly-acting treatment for the symptoms of SAD would be extremely valuable and life-changing for those individuals,” commented Dr. Liebowitz. “VistaGen’s PH94B presents a valuable opportunity for both the company and those affected by SAD. I am delighted to be working with VistaGen’s team to continue prior progress with PH94B. I believe pivotal studies of PH94B have exciting potential to demonstrate its usefulness in alleviating symptoms of social anxiety disorder and other anxiety states where rapid, on-demand relief would be of benefit to patients.”

About PH94B
PH94B was developed from proprietary compounds called pherines. Administered as a nasal spray, PH94B acts locally on peripheral nasal chemosensory receptors that trigger rapid activation of the limbic system areas of the brain associated with SAD. This mechanism of pharmacological action, the rapid onset of efficacy, and the excellent safety and tolerability profile shown in clinical trials make PH94B an excellent product candidate for the acute intermittent and long-term treatment of individuals with SAD.

About Social Anxiety Disorder
Social Anxiety Disorder, SAD, is a debilitating social phobia affecting as many as 15 million American adults and is the fourth most common psychiatric condition after depression, specific phobias and substance use.1 SAD is characterized by a persistent and unreasonable fear of one or more social or performance situations, where the individual fears that he or she will act in a way or show symptoms that will be embarrassing or humiliating, leading to avoidance of the situations when possible and anxiety or distress when they occur.1 These fears have a significant impact on the person’s employment, social activities and overall quality of life. Currently, only antidepressants, administered chronically, are FDA-approved for treatment of SAD. However, such antidepressants have a slow onset of effect (often several weeks to months) and have a range of known side effects that may make them unattractive to individuals often situationally affected by SAD.
