Designation highlights serious unmet need for new treatment options for patients suffering from neuropathic pain
Second FDA Fast Track designation for AV-101 since December 2017 marks another milestone for VistaGen's R&D pipeline
SOUTH SAN FRANCISCO, Calif., Oct. 03, 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 that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for development of AV-101 as a non-opioid, non-sedating treatment for neuropathic pain. This is the second FDA Fast Track designation granted to VistaGen since December 2017.
The FDA’s Fast Track designation is designed to facilitate the development, and potentially expedite the review, of drugs to treat serious or life-threatening conditions and fill an unmet medical need.
AV-101 is an investigational, orally bioavailable, small molecule NMDA (N-methyl-D-aspartate) receptor glycine B antagonist without psychological or sedative side effects.
“Every day in the U.S., more than 115 people die from overdosing on opioids. We have evaluated AV-101 in multiple models of serious CNS conditions, including those that cause patients to suffer from neuropathic pain, for which current treatment options are inadequate. After considering peer-reviewed data published last year in The Journal of Pain, together with published safety data from our Phase 1 program, we believe AV-101 has the potential to address the high unmet need for a new non-opioid, non-sedating treatment for neuropathic pain,” said Shawn Singh, Chief Executive Officer of VistaGen. “This important designation is especially timely given the FDA’s forceful commitment to address our nation’s opioid epidemic. The FDA’s Fast Track designation for development of AV-101 for neuropathic pain, together with the previously granted Fast Track designation for major depressive disorder, will allow our team to work closely with the FDA to bring AV-101 to patients affected by two of our country’s most debilitating and widespread healthcare concerns as soon as possible.”
VistaGen’s receipt of the FDA’s Fast Track designation for the development of AV-101 for neuropathic pain comes on the heels of the recent official statement made by FDA Commissioner Scott Gottlieb, stating that the FDA plans to issue guidance documents to assist sponsors with the development of new non-opioid pain medications, such as AV-101, as therapeutic alternatives to the use of opioids. More specifically, over the next 6 to 12 months, the FDA has stated it anticipates issuing several documents intended to stimulate the development of medications for specific types of pain, resulting in smaller clinical trials, faster approvals and quicker launches of novel therapies.1
About Neuropathic Pain
Neuropathic pain (NP) affects approximately 33 million people in the United States (excluding patients with back pain).2 It is characterized by a steady burning or "pins and needles" or "electric shock" sensation that results in abnormal neuronal function after trauma to the nerve, viral infections, certain medications, or metabolic insults.
About AV-101
AV-101 is an investigational, orally bioavailable, small molecule NMDA (N-methyl-D-aspartate) receptor glycine B antagonist without psychological or sedative side effects. AV-101 has potential to be a new at-home treatment for multiple CNS indications with high unmet need. AV-101 is currently in Phase 2 clinical development in the United States for major depressive disorder (MDD). 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 individuals with an inadequate response to standard antidepressant therapy with either an FDA-approved SSRI or SNRI. The FDA has granted Fast Track designation for development of AV-101 as a potential treatment of MDD and neuropathic pain.

Forward-Looking Statements
This release contains various statements concerning VistaGen's future expectations, plans and prospects, including without limitation, our expectations regarding development of AV-101 and the potential of AV-101 for the treatment of MDD, NP and various other CNS diseases and disorders constitute forward-looking statements for the purposes of the safe harbor provisions under the Private Securities Litigation Reform Act of 1995. These forward-looking statements are neither promises nor guarantees of future performance and are subject to a variety of risks and uncertainties, many of which are beyond our control, and may cause actual results to differ materially from those contemplated in these forward-looking statements. Among these risks is the possibility that (i) we may encounter unexpected adverse events in patients in our ELEVATE study or other clinical studies that cause us to discontinue further development of AV-101, (ii) we may not be able to successfully demonstrate the safety and efficacy of AV-101 at each stage of clinical development, (iii) success in preclinical studies or in early-stage clinical trials may not be repeated or observed in ongoing or future AV-101 studies, and ongoing or future preclinical and clinical results may not support further development of AV-101 or be sufficient to gain regulatory approval to market AV-101, (iv) decisions or actions of regulatory agencies may negatively affect the initiation or progress of ongoing or future AV-101 clinical trials, and our ability to proceed with further clinical studies or to obtain marketing approval, (v) we may not be able to obtain or maintain adequate intellectual property protection and other forms of marketing and data exclusivity for AV-101, (vi) we may not have access to or be able to secure substantial additional capital required to support our operations, including clinical development of AV-101 activities described above; and (vii) we may encounter technical and other unexpected hurdles in the manufacturing and development of AV-101. Certain other risks are more fully discussed in the section entitled "Risk Factors" in our most recent annual report on Form 10-K, and subsequent quarterly reports on Form 10-Q, as well as discussions of potential risks, uncertainties, and other important factors in our other filings with the Securities and Exchange Commission (SEC).
