Shire plc (LSE: SHP, NASDAQ: SHPGY), the global specialty biopharmaceutical company, today announced the expansion of its Human Genetic Therapies pipeline through the exclusive license, in markets outside of North America, for the activin receptor type IIB (ActRIIB) class of molecules being developed by Acceleron Pharma Inc., a private biotechnology company based in Cambridge, Massachusetts. The collaboration will initially investigate ACE-031, Acceleron's lead ActRIIB drug candidate, currently in a Phase 2a trial for the treatment of patients with Duchenne Muscular Dystrophy (DMD). DMD is a fatal orphan muscle disease with no current treatment. ACE-031 and other ActRIIB molecules have the potential to be used in other muscular and neuromuscular disorders with high unmet medical need.
Shire and Acceleron will jointly collaborate on a worldwide development program to advance ACE-031 into a global Phase 2/3 clinical program designed to demonstrate disease modification in DMD patients. Shire will utilize its Lexington, Massachusetts manufacturing facility to produce commercial supplies of the product for both parties. If marketing authorization is received, Acceleron will commercialize ACE-031 in the U.S. and Canada, and Shire has the exclusive right to commercialize the therapy in the rest of the world.
