Neumora Therapeutics, Inc. announced the initiation of a Phase 1 single ascending dose /multiple ascending dose study evaluating NMRA-266 in healthy adult participants. NMRA-266 is a highly selective positive allosteric modulator of the M4 muscarinic receptor that Neumora is developing as a treatment for schizophrenia and other neuropsychiatric disorders. Neumora believes that as a selective M4 receptor-positive allosteric modulator, NMRA-266 has the potential to deliver antipsychotic efficacy, while minimizing the side effects associated with current antipsychotics and other non-selective muscarinic agonists.
