ACE 031 is an investigational protein therapeutic that builds muscle and increases strength by inhibiting molecules that bind to and signal through a cell surface receptor called Activin Receptor Type IIB (ActRIIB). ACE 031 is a recombinant fusion protein that is produced by joining a portion of the person ActRIIB receptor to a portion of a person antibody.
