Neurocrine Biosciences and Sosei Heptares Announce Collaboration to Develop Novel Muscarinic Receptor Agonists for Schizophrenia and Other Neuropsychiatric Disorders
Neurocrine Biosciences anticipates initiating a Phase 2 study with the selective M4 agonist HTL-0016878 in schizophrenia in 2022 and Phase 1 studies for a dual M1/M4 and selective M1 agonist in 2023
SAN DIEGO and TOKYO and CAMBRIDGE, England, Nov. 22, 2021 /PRNewswire/ -- Neurocrine Biosciences, Inc., (Nasdaq: NBIX) and Sosei Group Corporation ("Sosei Heptares"; TSE: 4565) announce the signing of a strategic collaboration and licensing agreement to develop novel muscarinic receptor agonists, which Neurocrine Biosciences intends to study in the treatment for schizophrenia, dementia and other neuropsychiatric disorders.
Under the terms of the agreement, Neurocrine Biosciences 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 in development for the treatment of major neurological disorders. The most advanced program, HTL-0016878, is a selective M4 agonist. Neurocrine Biosciences plans to submit an Investigational New Drug (IND) application and initiate a placebo-controlled Phase 2 study with HTL-0016878 as a potential treatment for schizophrenia in 2022.
Sosei Heptares retains the rights to develop M1 agonists in Japan in all indications, with Neurocrine Biosciences receiving co-development and profit share options.
Muscarinic receptors are central to brain function and validated as drug targets in psychosis and cognitive disorders. Sosei Heptares has discovered selective muscarinic M4, M1 and M1/M4 dual agonists that offer the potential to deliver therapeutic effects while avoiding both the harmful side effects caused by non-selective agonists and efficacy issues experienced in some older patients caused by positive allosteric modulators that require cooperativity of diminishing levels of acetylcholine. Sosei Heptares achieved this through application of its world leading G protein-coupled receptor (GPCR) stabilized receptor platform (StaR®) and subsequent translational medicine studies.
"Our partnership collaboration with Sosei Heptares to advance their selective muscarinic agonist portfolio leverages the strengths of both our organizations with one goal in mind, to bring important medicines to patients who need better treatment options," said Kevin Gorman, Ph.D., Chief Executive Officer at Neurocrine Biosciences. "We continue to add potential best-in-class compounds to our growing pipeline, which further positions Neurocrine Biosciences as a leading neuroscience-focused biopharmaceutical company."
Shinichi Tamura, President and CEO of Sosei Heptares, added: "We are delighted to partner with Neurocrine Biosciences to advance our selective muscarinic receptor agonist portfolio. The deal highlights the significant potential value within this portfolio and brings to bear the substantial expertise of the Neurocrine team, which is highly experienced in developing and commercializing novel products for patients with neurological and psychiatric diseases globally. It also enables Sosei Heptares to retain rights in Japan, where we are confident that we can make important progress leveraging our own expertise to advance novel candidates that aim to address this major unmet need. Overall, the deal is a great example of our strategy to combine our drug design and early development capabilities with those of later stage development and commercialization partners, while also providing significant funding to expand and advance our own pipeline."
Under the terms of the agreement, Neurocrine Biosciences will be responsible for development costs associated with the programs globally, except for M1 agonists being developed in Japan. The agreement will be subject to the following terms:
This transaction is subject to customary clearances under the Hart-Scott-Rodino Antitrust Improvements Act. Assuming this transaction completes by December 31, 2021, the $100 million USD upfront payment will represent a material positive revenue impact to Sosei Heptares, and is expected to be recognized as revenue in the fourth quarter of the financial year ended December 31, 2021, subject to agreement with the Group's auditors.
BofA Securities is acting as financial advisor to Sosei Heptares. Gowling WLG and Orrick Herrington & Sutcliffe LLP are serving as legal counsel to Sosei Heptares.
Conference Call and Webcast Information
On Wednesday November 24, Sosei Heptares will host a conference call and webinar for Japanese investors at 8:00 a.m. Japan Standard Time. The live call may be accessed by pre-registration here.
A live audio webcast of the conference call will be available from the Investors section of Sosei Heptares website at www.soseiheptares.com.
A replay of the webcast will be available on Sosei Heptares' website after the conclusion of the event and will be archived for approximately one month.
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 Programs in the Collaboration Agreement
HTL-0016878 ("878") is an oral, investigational M4 selective agonist that has completed multiple Phase 1 studies and Neurocrine Biosciences is preparing to initiate Phase 2 studies in schizophrenia in 2022. As a selective M4 orthosteric agonist, '878 offers the potential for an improved safety profile without the need of combination therapy to minimize side effects and avoids the need of cooperativity with acetylcholine (ACh) when compared to non-selective muscarinic agonists and positive allosteric modulators in development. Studies completed to date have shown '878 to be generally well tolerated.
The collaboration includes rights to multiple preclinical programs which include selective muscarinic compounds targeting M1, M4 receptors and a dual M1/M4 receptor candidate. In combination with '878, the programs offer the ability to leverage M1 and M4 selectivity to address the unmet need for patients suffering from psychosis and cognitive-related diseases.
After signing a R&D and commercialization partnership in 2016, Allergan returned all program rights to '878 and the preclinical programs to Sosei Heptares in Q1 2021.
