Vistagen is a late clinical-stage biopharmaceutical company aiming to transform the treatment landscape for individuals living with anxiety, depression, and other CNS disorders. The Company is advancing therapeutics with the potential to be faster-acting, with fewer side effects and safety concerns, than those currently available. Its clinical-stage candidates are targeting multiple types of anxiety and depression. PH94B and PH10 belong to a new class of drugs known as pherines, which are designed with a novel rapid-onset mechanism of action that activates chemosensory neurons in the nasal passages and can impact the olfactory-amygdala neural circuits without systemic uptake or direct activity on CNS neurons in the brain. Vistagen is based in South San Francisco, California.
