TOKYO and CAMBRIDGE, United Kingdom, Oct. 28, 2022 (GLOBE NEWSWIRE) -- Sosei Group Corporation (“the Company”; TSE: 4565), the world leader in G protein-coupled receptor (GPCR) focused structure-based drug design (SBDD) and development, notes its partner Neurocrine Biosciences Inc. (“Neurocrine”) announced the first patient has been randomized for its Phase 2 placebo-controlled, inpatient clinical study evaluating the efficacy, safety, tolerability, and pharmacokinetics of investigational compound NBI-1117568 in adults with schizophrenia. NBI-1117568 is an investigational, muscarinic M4 selective acetylcholine receptor agonist believed to be a key regulator of neurotransmitters impacted by schizophrenia.
“Initiation of this Phase 2 study for NBI-1117568 brings forward a first-in-class, orally active, highly selective investigational M4 agonist as a potential treatment for schizophrenia, a serious and complex psychiatric syndrome impacting 0.5-1.0% of the U.S. population and approximately 20 million people worldwide,” said Eiry W. Roberts, M.D., Chief Medical Officer of Neurocrine Biosciences. “The differentiated profile of NBI-1117568 in terms of its selectivity as an M4 agonist may provide an opportunity for efficacy in treating the symptoms of psychosis with a potentially different side effect profile.”
The NBI-1117568 Phase 2 multi-arm, multi-stage study will enroll approximately 200 adults and is being conducted at 15 centers throughout the United States. The placebo-controlled study will evaluate multiple active dose levels of NBI-1117568. The primary outcome measure will be the change in total Positive and Negative Syndrome Scale (PANSS) score from baseline to Week 6.

About Muscarinic Receptors
Muscarinic receptors are G protein-coupled receptors (GPCRs) found in multiple tissues including the brain, cardiovascular system, and gastrointestinal tract. Selective activation of M4 and M1 receptors in the brain is a clinically validated approach to treating cognitive and neuropsychological symptoms of neurological diseases, including Schizophrenia, dementia associated with Alzheimer’s disease, Parkinson’s disease, and others.
Until now, attempts to develop medicines that selectively target M4 and M1 receptors have been unsuccessful because of side effects caused by the activation of M2 and M3 receptors. Highly selective M4 or M1 agonists that do not activate M2 or M3 therefore are highly sought after and expected to have the potential to address major unmet medical needs with blockbuster potential.
About the Agreement with Neurocrine Biosciences
Sosei Heptares and Neurocrine entered a collaboration and licensing agreement in November 2021 to develop novel muscarinic receptor agonists for the treatment of schizophrenia, dementia and other neuropsychiatric disorders.
Under the terms of the agreement, Neurocrine gains development and commercialization rights to a broad portfolio of novel clinical and preclinical subtype-selective muscarinic M4, M1 and dual M1/M4 receptor agonists discovered by Sosei Heptares. Neurocrine is responsible for development costs associated with the programs globally, except for M1 agonists being developed in Japan. Sosei Heptares retains rights to develop M1 agonists in Japan for any indication, with Neurocrine receiving co-development and profit share options.
Sosei Heptares is eligible to receive R&D funding plus development, regulatory and commercial milestones of up to US$2.6 billion, with further product royalties, provided the criteria under the agreement are satisfied.
