CAMBRIDGE, Mass.--(BUSINESS WIRE)--Acceleron Pharma, Inc., a biopharmaceutical company developing novel therapeutics that modulate the growth of cells and tissues including muscle, bone, fat, red blood cells and the vasculature, today announced preliminary results from a Phase 1b study to assess the safety, tolerability and pharmacodynamic (PD) activity of ACE-031 following multiple ascending doses in healthy postmenopausal volunteers. ACE-031 is an investigational protein therapeutic designed to build muscle and increase strength by blocking proteins that inhibit muscle growth. In the trial, ACE-031 was generally well-tolerated with rapid and sustained effects on muscle, bone and fat. Preliminary results from this randomized, placebo-controlled study were presented at the 15th International Congress of the World Muscle Society in Kumamoto, Japan.
