SAN DIEGO, Sept. 11, 2023 /PRNewswire/ -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX), today announced the initiation of its Phase 1 first-in-human clinical study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of investigational compound NBI-1117570 in healthy adult participants. NBI-1117570 is an investigational, oral, muscarinic M1/M4 selective dual agonist that may have the potential to treat neurological and neuropsychiatric conditions.

"Initiation of this Phase 1 study represents an important step forward for NBI-1117570, a potentially first-in-class, orally active, selective investigational dual M1/M4 agonist," said Eiry W. Roberts, M.D., Chief Medical Officer at Neurocrine Biosciences. "The selectivity profile of NBI-1117570 in targeting M1 and M4 receptors may provide an opportunity to treat symptoms of both psychosis and cognition across a broad range of neurological and neuropsychiatric conditions."

About NBI-1117570

NBI-1117570 is an investigational, oral, muscarinic M1/M4 dual agonist. Muscarinic receptors are fundamental to activating signaling pathways in the brain. There are five muscarinic acetylcholine receptors involved in neurotransmission, two of which are selectively targeted by NBI-1117570 (M1 and M4), with M1 validated as a potential drug target in cognition and M4 in psychosis for clinical drug development. Neurocrine Biosciences acquired the rights to develop and commercialize NBI-1117570 from Sosei Heptares.
