Vistagen Announces Closing of Pherin Pharmaceuticals Acquisition

Friday, February 03, 2023

Vistagen, a late clinical-stage biopharmaceutical company aiming to transform the treatment landscape for individuals living with anxiety, depression, and other central nervous system (CNS) disorders, today announced the closing of its acquisition of Pherin Pharmaceuticals, Inc., a privately held drug development company focused on neuropsychiatric and neuroendocrine conditions (Pherin). Vistagen now owns all intellectual property rights to its two most advanced drug candidates, PH94B, currently in Phase 3 development for social anxiety disorder (SAD) and Phase 2 development for adjustment disorder with anxiety (AjDA), and PH10, in clinical development for major depressive disorder (MDD), as well as three additional drug candidates in earlier stages of development: PH15 for cognition improvement; PH80 for migraine and hot flashes; and PH284 for appetite-related disorders. Vistagen’s acquisition of Pherin eliminates all future royalty payment obligations related to its five pherine nasal spray drug candidates.

“This acquisition is another important step in our plan to develop and commercialize PH94B and PH10 as innovative treatments for millions of individuals struggling with anxiety and depression disorders,” stated Shawn Singh, Chief Executive Officer of Vistagen. “By acquiring Pherin, we are eliminating all potential royalty payment obligations related to PH94B and PH10, as well as the three additional earlier stage pherines acquired in the transaction. This acquisition significantly improves the potential future commercial profile of each drug candidate.”

Additional details regarding the closing of Vistagen’ acquisition of Pherin can be found in the Company’s Current Report on Form 8-K, filed with the U.S. Securities and Exchange Commission today and available in the Investors section of Vistagen’s website.
