— Expands Allergan’s Innovative GI Pipeline with ABI-M201 and ABI-M301, Preclinical Compounds Targeting Ulcerative Colitis and Crohn’s Disease, as well as Future Compounds for Irritable Bowel Syndrome —

DUBLIN, Ireland and INDIANAPOLIS, IN, USA I January 9, 2017 I Allergan plc (NYSE: AGN) and Assembly Biosciences, Inc. (NASDAQ: ASMB) today announced that Allergan has entered into a research, development, collaboration and license agreement for the worldwide rights to Assembly’s microbiome gastrointestinal (GI) development programs. The agreement provides Allergan with worldwide rights to preclinical compounds ABI-M201 and ABI-M301, targeting ulcerative colitis (UC) and Crohn’s disease (CD), as well as two additional compounds to be identified by Assembly for Irritable Bowel Syndromes (IBS); with Diarrhea (IBS-D), with Constipation (IBS-C) or Mixed (IBS-M).

Under the terms of the agreement, Allergan will make an upfront payment to Assembly of $50 million for the exclusive, worldwide rights to develop and commercialize the UC, CD and IBS compounds. Additionally, Assembly will be entitled to receive success-based development and commercial milestone payments. Assembly is also eligible to receive tiered royalties based on net sales. Allergan and Assembly will generally share development costs through proof-of-concept (POC) studies, and Allergan will assume all post-POC development costs.

The Assembly microbiome program consists of a fully integrated platform that includes a robust strain identification and selection process, methods for strain isolation and growth under current Good Manufacturing Practices and a patent-pending delivery system, GEMICEL®, which allows for targeted oral delivery of live biologic and conventional therapies to the lower gastrointestinal tract.  

“The Microbiome — the microbial populations that colonize the human body — is rapidly gaining prominence in numerous fields of research relevant to Allergan’s key areas of focus, including GI disorders,” said David Nicholson, Chief R&D Officer, Allergan.  “Assembly is well positioned to identify and select unique therapeutic candidates and deliver them to the optimal site in the GI tract through a novel oral delivery system.”

This collaboration reinforces Allergan’s commitment to building a robust portfolio through Open Science.  As with most of our agreements, we enter into partnerships which, through creative structures, leverage the expertise of our partners to potentially deliver innovative treatments for improved patient care.

“Our fully-integrated microbiome platform reflects Assembly’s commitment as one of the leaders in the exciting new field of microbiome therapeutics, which has the potential to address a range of diseases in entirely new ways,” said Derek Small, Chief Executive Officer of Assembly. “We are delighted to enter into this collaboration with Allergan, an innovator in GI, as we work together to realize the potential of microbiome therapies and provide treatments to patients with serious GI disorders.”

“Inflammatory diseases of the GI tract, including Crohn’s disease and ulcerative colitis, are debilitating conditions that remain poorly treated for many patients,” said Martin J. Blaser, MD, Director of the New York University Human Microbiome Program.  “Therapies leveraging the microbiome may be able to address these disorders in fundamentally new ways. I am encouraged that microbiome innovators such as Assembly and Allergan are working to convert their promising new approaches into clinically useful products to help these patients.”

The transaction is expected to close in the first quarter of 2017, subject to customary closing conditions, including the expiration or early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

About Crohn’s Disease and Ulcerative Colitis[1],[2]

Crohn’s disease and ulcerative colitis are chronic inflammatory conditions of the gastrointestinal tract. Crohn’s disease most commonly affects the end of the small bowel (the ileum) and the colon (also called the large intestine), but it may affect any part of the gastrointestinal (GI) tract, from the mouth to the anus. Ulcerative colitis is limited to the colon. It is estimated that 1.6 million Americans and 2.2 million Europeans suffer from Crohn’s disease or ulcerative colitis. The majority of patients are diagnosed in young adulthood and these incidence rates continue to rise, which will continue to place a significant burden on global healthcare systems.
