Neumora initiates phase 1 study of NMRA-266 to treat schizophrenia & other neuropsychiatric disorders

Neumora Therapeutics, Inc. (Neumora), a clinical-stage biopharmaceutical company redefining neuroscience drug development, 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.

“The initiation of this phase 1 study is an important step in the development of NMRA-266. In pre-clinical studies NMRA-266 demonstrated a favourable pharmacologic profile that includes high potency and selectivity for the M4 receptor subtype, meriting its advancement into the clinic,” said Robert Lenz, M.D. Ph.D., executive vice president and head of research and development, Neumora. “With its pre-clinical profile and clinical validation of the M4 muscarinic receptor class in treating schizophrenia, we believe that NMRA-266 has strong potential as a treatment for 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.

“Muscarinic receptor-targeting compounds have demonstrated robust activity in multiple clinical trials, reinforcing the potential of this class of medicines as an approach to treating schizophrenia and other neuropsychiatric disorders,” said John H. Krystal, M.D., Robert L. McNeil, Jr. Professor of Translational Research and Professor of Psychiatry, of Neuroscience, and Psychology, and chair of the Yale Department of Psychiatry at Yale School of Medicine. “Schizophrenia is a serious and debilitating disorder. Limitations in the effectiveness of existing treatments result in significant unmet medical need. Pharmacologic treatment is an integral part of a comprehensive treatment plan, and finding the right treatment option for each patient is vitally important. As such, it’s encouraging to see the development of multiple products within the muscarinic class that may help people with schizophrenia find a treatment that works for them.”

NMRA-266 is an investigational positive allosteric modulator of the M4 muscarinic receptor subtype. While current antipsychotics approved for schizophrenia work primarily by blocking D2 dopamine receptors, growing evidence supports the approach of targeting the M4 muscarinic receptor to elicit antipsychotic effects, without the side effects associated with the first- and second-generation antipsychotics. M4 muscarinic receptor-targeting compounds have shown robust antipsychotic activity in multiple, placebo-controlled clinical trials, demonstrating potential as an approach to treating schizophrenia. Neumora exclusively licensed certain intellectual property rights related to NMRA-266 from Vanderbilt University, including composition of matter patent extending to 2042.

Schizophrenia is a debilitating neuropsychiatric disorder characterized by positive symptoms (such as delusions and hallucinations), negative symptoms (such as diminished emotional expression) and cognitive symptoms (such as deficits in types of memory) that impacts approximately 3 million adults in the United States. Currently approved therapies for schizophrenia are often associated with potentially serious side effects, including movement and metabolic effects, and no therapies with a novel mechanism of action have been recently approved. Significant unmet medical need remains in the treatment of schizophrenia as a result of this paradigm. A study conducted by the National Institute of Mental Health found that approximately 75 per cent of people with schizophrenia discontinue medication within 18 months due in part to inefficacy or intolerable side effects.

Neumora Therapeutics, Inc. is a clinical-stage biopharmaceutical company founded to confront the global brain disease crisis by taking a fundamentally different approach to the way treatments for brain diseases are developed.
