Acceleron is dedicated to the discovery and development of innovative, life-changing medicines for patients with a wide range of serious and rare diseases. Our research focuses on harnessing the power of the TGF-beta protein superfamily, the target-rich area of biology behind the body’s remarkable capacity for cellular growth and repair. Our approach to drug discovery is driven by deep scientific expertise—and an urgency to deliver effective treatments to thousands of patients who have few or no therapeutic options. The Company’s lead product candidate, luspatercept, is being evaluated in two Phase 3 studies in a global partnership with Celgene to treat chronic, sometimes debilitating anemias in myelodysplastic syndromes (MDS) and beta-thalassemia. We are also advancing clinical programs in neuromuscular disorders and cancer, and preclinical research in fibrotic and other diseases.
