Alto Neuroscience, Inc. (ANRO) Research

Alto Neuroscience, Inc. operates as a biopharmaceutical entity in the clinical stage, specializing in the creation of novel psychiatric medications. Its development pipeline includes ALTO-100, an investigational therapy targeting individuals affected by major depressive disorder (MDD) and post-traumatic stress disorder. Also in its portfolio is ALTO-300, a small molecule designed to function as both a melatonergic agonist and serotonergic antagonist, exhibiting antidepressant properties for MDD patients. For addressing the cognitive impairments linked with schizophrenia, Alto Neuroscience is advancing ALTO-101, an innovative small molecule phosphodiesterase 4 inhibitor. The company's therapeutic candidates further extend to ALTO-203, a pioneering small-molecule histamine H3 receptor inverse agonist intended for MDD patients experiencing heightened anhedonia, and ALTO-202, an orally available antagonist of the GluN2B subunit of the NMDA receptor, also under investigation for MDD. Beyond these individual drug candidates, the firm is engaged in developing novel drug combinations that demonstrate synergistic pharmacodynamic effects. Crucially, Alto Neuroscience leverages an advanced AI-enabled biomarker platform that synthesizes data concerning patients' brain activity and behavioral patterns. This platform's purpose is to accurately identify which individuals are most likely to respond positively to its cutting-edge product candidates. Alto Neuroscience, Inc., established in 2019, maintains its headquarters in Los Altos, California.
