According to reports, sotatercept is a type IIa activin receptor (ActriIA) fusion protein. It combines the modified extracellular domain of ActriIA with the Fc terminal of the antibody to block activin binding to receptors on the cell membrane, thereby reducing activin-mediated signaling. In preclinical studies, it can reverse the remodeling of the pulmonary artery wall and right ventricle. This product is also a key therapy obtained by MSD's acquisition of Acceleron Pharma for approximately US$11.5 billion in 2021. Previously, Sotatercept was recognized as a breakthrough therapy by the FDA for the treatment of pulmonary hypertension.
