Neurocrine to conduct placebo-controlled Phase 2 study to investigate NBI-1117568 (formerly HTL-0016878) as a potential new treatment for schizophrenia
Clinical development milestone triggers payment of US$30 million to Sosei Heptares from Neurocrine
NBI-1117568 is the most advanced candidate under the multi-program muscarinic receptor agonist collaboration between Sosei Heptares and Neurocrine
TOKYO and CAMBRIDGE, United Kingdom, Aug. 05, 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, has been notified by its partner Neurocrine Biosciences Inc. (“Neurocrine”; Nasdaq: NBIX) that the U.S. Food and Drug Administration (FDA) Investigational New Drug (IND) Application for a Phase 2 clinical trial of NBI-1117568 for the treatment of schizophrenia has been accepted by the FDA and that the study may proceed. The achievement of this important clinical development milestone triggers a $30 million payment to Sosei Heptares from Neurocrine.
NBI-1117568 is an oral, selective muscarinic M4 receptor agonist in development for the treatment of schizophrenia and other neuropsychiatric disorders. As a selective M4 orthosteric agonist, NBI-1117568 offers the potential to deliver therapeutic effects without the need of combination therapy to minimize side effects, as required with non-selective muscarinic agonists, whilst also avoiding the requirement for cooperativity with acetylcholine (ACh) when compared to positive allosteric modulators. Clinical studies completed to date have shown NBI-1117568 to be generally well tolerated.
NBI-1117568 is the most advanced candidate from a broad portfolio of novel clinical and preclinical subtype-selective muscarinic M4, M1 and dual M1/M4 receptor agonists discovered by Sosei Heptares and in development under the 2021 collaboration with Neurocrine for the treatment of major neurological disorders. Upon successful completion of pre-clinical studies, Neurocrine anticipates initiating Phase 1 studies for a dual M1/M4 and selective M1 agonist. Advancing additional compounds into clinical studies would trigger further milestone payments from Neurocrine to Sosei Heptares.
Chris Cargill, President and CEO of Sosei Heptares, commented: “We are delighted with the progress of NBI-1117568 and of our collaboration with Neurocrine across our portfolio of novel selective M4 and M1 agonists. Muscarinic receptors are important drug targets in psychosis and cognitive disorders and through the application of our StaR® technology platform and expertise in GPCR-focused structure-based drug design, we have discovered agonists selective to M4 and M1. These novel drug candidates have been designed to deliver improved therapeutic effects while avoiding the unwanted activation of M2 and M3 and its associated side effects. Our selective muscarinic agonist approach is supported by significant scientific and clinical evidence reinforcing its potential to address major unmet needs in neurological and psychiatric diseases and we are excited to be advancing developments in this area with Neurocrine.”
Eiry Roberts, Chief Medical Officer of Neurocrine, commented: “We are excited to advance the lead asset in our strategic collaboration, NBI-1117568, into a Phase 2 study for the treatment of schizophrenia this year and look forward to our continued partnership with the Sosei Heptares team.”
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 Biosciences 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.
