Acceleron Pharma Inc

A maker of protein drugs for rare blood and lung diseases, Acceleron Pharma developed Reblozyl, an anemia treatment, and sotatercept for a form of pulmonary hypertension, from its base in Cambridge, Massachusetts. It was founded in 2003 under the name Phoenix Pharma before rebranding as Acceleron—a nod to "accelerate." Merck & Co. bought the company in 2021.
