Sotatercept improved right ventricular-pulmonary arterial (RV-PA) coupling and RV function in patients with pulmonary arterial hypertension (PAH). This was shown by new cardiac and pulmonary function data from the ongoing phase 2 PULSAR trial of sotatercept . This abstract won the AHA’s “Cardiopulmonary Best Abstract” award.
Sotatercept is a novel investigatory agent designed to be a selective ligand trap for members of the transforming growth factor (TGF)-β superfamily to reset signalling cascades that drive PAH. PULSAR (NCT03496207) is an ongoing, double-blind, placebo-controlled study in which PAH patients (mean age 48 years) were randomised in a 3:3:4 ratio to receive placebo, sotatercept 0.3 mg/kg, or sotatercept 0.7 mg/kg subcutaneously every 21 days over a 24-week treatment period, in combination with stable background PAH standard-of-care therapies.
