Nxera Pharma Notes Successful Development Progress of Partnered Schizophrenia Candidate NBI-1117568
- NBI-1117568 is an oral, selective muscarinic M4 receptor agonist advancing through Phase 2 clinical development under a multi-program collaboration with Neurocrine Biosciences
- Successful completion of a long-term preclinical toxicity program to support safe, chronic dosing of NBI-1117568 in future clinical trials triggers a $15 million payment to Nxera from Neurocrine Biosciences
Tokyo, Japan and Cambridge, UK, 16 April 2024 – Nxera Pharma Co., Ltd. ("Nxera" or "the Company; TSE 4565) – formerly known as Sosei Group or Sosei Heptares – has been notified by its partner Neurocrine Biosciences Inc. (("Neurocrine", NASDAQ:NBIX) that NBI-1117568, an oral selective muscarinic M4 receptor agonist being advanced in Phase 2 clinical trials by Neurocrine for the treatment of schizophrenia and other neuropsychiatric disorders, has successfully completed a long-term preclinical toxicity program that meets US FDA requirements to allow for safe, chronic (i.e. long-term) dosing in future clinical trials. The achievement of this important safety development milestone triggers a $15 million payment to Nxera from Neurocrine.
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 Nxera and advancing under the 2021 global collaboration with Neurocrine for the treatment of major neurological disorders. These candidates have potential to address a range of neurological and neuropsychiatric conditions and include:
- NBI-1117568 (an M4 selective agonist) in Phase 2 trials with top-line data expected in H2 2024
- NBI-1117570 (an M1/M4 selective dual agonist) in Phase 1
- NBI-1117569 (an M4-preferring agonist) in Phase 1
- NBI-1117567* (an M1-preferring agonist) expected to enter Phase 1 in 2024
Matt Barnes, EVP, President of Nxera Pharma UK and Head of R&D, commented: "We are delighted that NBI-1117568 has successfully achieved this important safety development milestone. These results will support the safe, long-term use of this novel clinical candidate, which is consistent with a desired product profile for schizophrenia and other neurological diseases where patients often need therapy over many years. We are extremely pleased at the progress being made under our highly productive partnership with Neurocrine and look forward to reporting further progress and upcoming clinical data readouts, including the top-line Phase 2 data on NBI-1117568, which is expected in the second half of 2024."

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 NBI-1117568
NBI-1117568 is an oral, selective muscarinic M4 receptor agonist discovered by Nxera Pharma and being developed in Phase 2 clinical trials by Neurocrine 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.
About the Agreement with Neurocrine Biosciences
Nxera Pharma and Neurocrine BioSciences 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 Nxera. Neurocrine is responsible for development costs associated with the programs globally, except for M1 agonists being developed in Japan. Nxera retains rights to develop M1 agonists in Japan for any indication, with Neurocrine receiving co-development and profit share options.
Nxera 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.
