SAN DIEGO, CA, USA I March 28, 2024 I Neurocrine Biosciences, Inc. (Nasdaq: NBIX), today announced the initiation of its Phase 1 clinical study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of investigational compound NBI-1065890 in healthy adult participants. NBI-1065890 is an investigational, oral, selective inhibitor of the vesicular monoamine transporter-2 (VMAT2) for the potential treatment of certain neurological and neuropsychiatric conditions.  

“Neurocrine has deep scientific expertise and experience in VMAT2 inhibition, exemplified by the successful discovery and development of valbenazine for the treatment of tardive dyskinesia and chorea in Huntington’s disease,” said Eiry W. Roberts, M.D., Chief Medical Officer at Neurocrine Biosciences. “We’re excited to bring this next-generation, internally discovered, highly potent, oral, selective VMAT2 inhibitor into the clinic with the hope of providing differentiated benefit in treating certain neurological and neuropsychiatric conditions.”

VMAT2 small molecule inhibitors have been clinically validated as effective treatments for hyperkinetic movement disorders, playing an important role in presynaptic dopamine storage and release. Neurocrine successfully developed and received U.S. Food and Drug Administration approval in 2017 for valbenazine, a selective VMAT2 inhibitor, for use as the first drug ever developed for the treatment of tardive dyskinesia. In 2023, the company received FDA approval for valbenazine as a treatment for chorea associated with Huntington’s disease.
