VistaGen Therapeutics, Inc. is a clinical-stage biopharmaceutical entity dedicated to advancing and commercializing innovative medications for anxiety, depression, and various other disorders impacting the central nervous system (CNS). A key component of its CNS pipeline is PH94B, a fast-acting neuroactive nasal spray currently in Phase III trials for the rapid treatment of anxiety in adults experiencing social anxiety disorder. PH94B also shows potential for addressing a broader spectrum of anxiety conditions, including adjustment disorder with anxiety, postpartum anxiety, post-traumatic stress disorder (PTSD), pre-procedural anxiety, and panic disorders. The company's CNS development initiatives further encompass PH10, another quick-acting neuroactive nasal spray, which is in preparation for Phase 2B clinical assessment as a standalone therapy for major depressive disorder (MDD). Additionally, VistaGen is developing AV-101, an oral N-methyl-D-aspartate receptor antagonist, which is being investigated in conjunction with oral probenecid for its potential application in treating levodopa-induced dyskinesia, MDD, neuropathic pain, and suicidal ideation. VistaGen has established various collaborations, including a contract research and development agreement with Cato Research Ltd., a licensing agreement with Pherin Pharmaceuticals, Inc., and a license and collaboration agreement with EverInsight Therapeutics Inc.
