TOKYO

Sosei Group Corporation (“Sosei”; TOKYO Mothers Index: 4565) today announces that its wholly-owned subsidiary, Heptares Therapeutics has entered into a definitive agreement with Allergan Pharmaceuticals International Limited, a wholly owned subsidiary of Allergan plc, a leading global pharmaceutical company, under which Allergan will license exclusive global rights to a broad portfolio of novel subtype-selective muscarinic receptor agonists in development for the treatment of major neurological disorders, including Alzheimer’s disease.

Under the terms of the agreement, Heptares will receive an upfront payment of $125 million and is eligible to receive contingent milestone payments of up to approximately $665 million associated with the successful Phase 1, 2 and 3 clinical development and launch of the first three licensed compounds for multiple indications and up to approximately $2.5 billion associated with achieving certain annual sales thresholds during the several years following launch. In addition, Heptares is eligible to receive up to double-digit tiered royalties on net sales of all products resulting from the partnership. Allergan is also committing up to $50 million to a research and development program to be conducted jointly by Allergan and Heptares aimed at advancing multiple candidates through Phase 2 clinical studies. Allergan will be responsible for the development of licensed compounds upon initiation of Phase 2b studies and for subsequent manufacturing and commercialization of the products.

The agreement covers first-in-class selective small molecule agonists targeting muscarinic M1 and M4 receptors in the brain, discovered using Heptares’ proprietary StaR® technology platform. Allergan will receive exclusive rights to a broad clinical and preclinical portfolio of M1, M4 and dual M1/M4 agonists, including HTL9936 and HTL18318, selective M1 agonists currently in Phase 1 clinical development.

M1 selective compounds are in development for the potential treatment of symptomatic cognitive deficits in Alzheimer’s patients, with the potential upside of better tolerability and a more pronounced effect compared with available treatments. M4 selective compounds may provide a novel approach to treat the neurobehavioral symptoms (psychoses) associated with Alzheimer’s disease and related neurological disorders, through a different mechanism of action than available antipsychotics. Combined, dual M1/M4 agonists may be able to treat both cognitive impairment and neurobehavioral symptoms.

“Cognitive impairment and psychosis are progressive and debilitating symptoms associated with many CNS diseases, including Alzheimer’s disease, with few approved therapies available,” said David Nicholson, Executive Vice President and President, Global Brands Research and Development at Allergan. “The Heptares M1 compounds have shown promising results in early development in their ability to selectively target the M1 receptor without also activating the M2 or M3 receptors, which are associated with undesirable side effects. We look forward to advancing these compounds into the next stages of development, and potentially adding new approaches to helping physicians treat patients suffering from the effects of Alzheimer’s disease, an area of medicine where Allergan remains committed to continued innovation.”

The safety, tolerability and pharmacokinetic profile of HTL9936 were assessed in a recently completed Phase 1 study. The data provide strong evidence of a therapeutic window for the selective M1 agonist mechanism in general, and for progression of HTL9936 and similar molecules as medicines to treat cognitive disorders. HTL9936 exhibited good brain penetration and M1 selectivity with no adverse events typically attributed to the stimulation of M2 and M3 receptors. HTL9936 also exhibited robust and statistically significant changes in brain electrical activity measured using multiple electroencephalography (EEG) biomarkers relevant to cognition. These pro-cognitive effects were seen at low doses and low blood concentrations that were safe and well tolerated.

Malcolm Weir, Chief Executive Officer of Heptares and Chief R&D Officer at Sosei, said: “We are delighted that the quality of our muscarinic agonist candidates, discovered and developed wholly in-house, and our translational capabilities have been recognized by Allergan, a global leader in the development and commercialization of treatments for CNS diseases. We have a highly committed and experienced partner in Allergan and look forward to working together towards the development of multiple new breakthrough medicines over the coming years.”

Shinichi Tamura, Chairman and CEO of Sosei Group Corporation, added: “This new agreement with Allergan marks an important milestone in our journey to become a global biopharmaceutical company. This agreement further endorses our strategic decision to acquire Heptares in February last year, placing its GPCR-directed drug discovery and development capabilities at the heart of our business.”

This transaction is subject to customary clearances under the Hart-Scott-Rodino Antitrust Improvements Act.

Sosei was advised by Moelis & Company.

About Muscarinic Receptors

Muscarinic receptors are G protein-coupled receptors (GPCRs) found in multiple tissues. Until now, attempts to develop medicines that target M1 and M4 receptors have been unsuccessful because of side effects caused by the activation of M2 and M3 receptors. Selective M1 or M4 agonists that do not activate M2 or M3 therefore are highly sought after, and expected to address blockbuster markets.

About Cognitive Impairment in Alzheimer’s Disease and other CNS Diseases1

Today there is significant unmet medical need and heavy economic burden across multiple diseases characterized by cognitive impairment and dementia. In Alzheimer’s disease (AD), currently available drugs provide limited and transient effects on cognition. Healthcare costs associated with AD and dementia (estimated at over $640 billion for North America, Western Europe and Asia-Pacific) including nursing home care, continue to grow dramatically and new therapies with better and more durable efficacy are urgently needed. It is estimated that over 45 million people worldwide have dementia (4.8 million in North America, 7.5 million in Western Europe, 3.6 million in Asia-Pacific) and this is expected to increase to over 130 million in 2050. Alzheimer’s disease is the most common cause of dementia and may contribute to 60–70% of cases. In addition, an estimated 1.4 million patients in the US suffer from Lewy body dementia.
