CAMBRIDGE, Mass.--(BUSINESS WIRE)--Acceleron Pharma Inc. (NASDAQ:XLRN), a leading biopharmaceutical company in the discovery and development of TGF-beta superfamily therapeutics to treat serious and rare diseases, today announced it is discontinuing development of ACE-2494, a systemic muscle agent the company had been studying in a Phase 1 healthy volunteer trial for the potential treatment of neuromuscular disorders.
“Although ACE-2494 showed promising early signs of target engagement in our recently completed Phase 1 trial, the frequency of anti-drug antibodies (ADAs) observed among participants has led us to discontinue the program,” said Habib Dable, President and Chief Executive Officer of Acceleron. “The formation of ADAs was not associated with any adverse event, but the ADA profile is not consistent with a clinical program that Acceleron would advance. We greatly appreciate the efforts of those who participated in this trial, and plan to leverage the clinical data to help inform future drug discovery efforts in neuromuscular disease.”
Acceleron is a clinical-stage biopharmaceutical company dedicated to the discovery, development, and commercialization of therapeutics to treat serious and rare diseases. The Company's leadership in the understanding of TGF-beta biology and protein engineering generates innovative compounds that engage the body's ability to regulate cellular growth and repair.
Acceleron focuses its research and development efforts in hematologic, neuromuscular, and pulmonary diseases. In hematology, the Company and its global collaboration partner, Celgene, are developing luspatercept for the treatment of chronic anemia in myelodysplastic syndromes, beta-thalassemia, and myelofibrosis. Acceleron is also advancing its neuromuscular program with ACE-083, a locally-acting Myostatin+ agent in Phase 2 development in facioscapulohumeral muscular dystrophy and Charcot-Marie-Tooth disease and is conducting a Phase 2 pulmonary program with sotatercept in pulmonary arterial hypertension.
