Harnessing serotonin neurobiology
to drive breakthroughs for complex mental illness
We are a biopharmaceutical company focused on discovery and development of small molecule drugs with a broad-spectrum of therapeutic activity for treating a range of neuropsychiatric and mental health conditions. Our mission is to bring to patients safe pharmaceutical options that will provide rapid and sustained benefit beyond what current standards of treatment can offer.
Onsero’s drug discovery engine focuses on the neurobiology of the 5-HT2A serotonin receptor which is present throughout the brain and is essential for learning, cognition, memory, and other mental processes that can be altered in certain pathological states.
We are taking advantage of recent advances in the field of molecular biology and biochemistry to harness the neurobiology of the 5-HT2A receptor and create a new class of psychopharmaceuticals.
