Cardiovascular Approved 2024-03-26

WINREVAIR (sotatercept-csrk) is an activin signaling inhibitor indicated for the treatment of adults with pulmonary arterial hypertension (PAH, WHO Group 1). The therapy is used to improve exercise capacity and World Health Organization (WHO) functional class in this patient population. Additionally, it is intended to reduce the risk of clinical worsening events, including hospitalization for PAH, lung transplantation, and death.

How WINREVAIR Works

Sotatercept-csrk is a recombinant fusion protein that binds to activin A and other TGF-β superfamily ligands to inhibit activin signaling. This process improves the balance between pro-proliferative and anti-proliferative signaling pathways to modulate vascular proliferation. By regulating these pathways, the drug inhibits the proliferation of endothelial and smooth muscle cells in diseased vasculature. These cellular changes are associated with thinner vessel walls, improved hemodynamics, and the partial reversal of right ventricular remodeling.
