Takeda has evaluated the safety, tolerability, pharmacokinetics, and pharmacodynamics of NBI-1117570 from Neurocrine Biosciences Inc. (Nasdaq: NBIX), a leading biotechnology company specializing in neurological diseases. We would like to inform you that we have started a Phase I clinical trial on healthy adults. NBI-1117570 is an oral muscarinic M1/M4 dual receptor agonist that is expected to be a treatment for neurological and neuropsychiatric disorders.
Eiry W. Roberts, M.D., chief medical officer (CMO), Neurocrine, said, “The initiation of a Phase I clinical trial of NBI-1117570 represents an important step forward for this potentially first-in-class orally available dual M1/M4 receptor agonist. Selectivity has the potential to treat both psychiatric and cognitive symptoms in a wide range of neurological and neuropsychiatric disorders.”
Matt Burns, President and Head of UK Research and Development at Heptares Therapeutics, said: “NBI-1117570 will be available at Neurocline in 2021 to advance clinical development of a dual M1/M4 receptor agonist to address significant unmet medical needs in neurological and neuropsychiatric diseases. We are the second in our portfolio of muscarinic receptor agonists to enter clinical trials, out-licensed at We look forward to reporting further developments.” Please note that there are no milestone payments associated with this release. The Company may receive milestones related to the Phase I clinical trial under NBI-1117570, the terms of which will be determined in a separate agreement. We will keep you informed of any such developments in the future.
that’s all
About NBI-1117570
NBI-1117570 is an oral muscarinic M1/M4 dual receptor agonist. Muscarinic receptors play an important role in the activation of signal transduction pathways in the brain. There are five subtypes of muscarinic acetylcholine receptors involved in neurotransmission, and selective action on two of them (M1 and M4) is clinically effective as a drug target for cognitive function (M1) and for psychosis (M4). This is an approach that is being evaluated. Neurocline has acquired the rights to research, develop, and commercialize NBI-1117570 from our group.
About the contract with Neurocline
In November 2021, the Group and Neurocline entered into a strategic agreement regarding a novel muscarinic receptor agonist, with the aim of Neurocline developing drugs for the treatment of schizophrenia, dementia, and other neuropsychiatric disorders. We have concluded a research and development partnership and license agreement.
Under this agreement, Neurocline will acquire novel subtype-selective muscarinic M4, M1 and M1/M4 dual-molecular drugs that the Group has discovered and are developing and in clinical and preclinical stages for the treatment of major neurological diseases. We have acquired research, development and commercialization rights to a broad portfolio of receptor agonists. Neurocline will bear the global development costs associated with this program, except for the M1 receptor agonist being developed in Japan. The Group holds the rights to develop and commercialize muscarinic M1 receptor agonists for all indications in Japan, and Neurocline holds joint development and co-marketing rights for muscarinic M1 receptor agonists in Japan. Holds option rights.
