Semaglutide in Patients Undergoing Transcatether Aortic Valve Replacement

This is a Phase III, randomized, double-blind, placebo-controlled, multicenter clinical trial evaluating the safety and efficacy of once-weekly semaglutide 2.4 mg in adult patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) who meet current clinical criteria for semaglutide treatment. A total of 826 participants will be randomized 1:1 to receive semaglutide or placebo as an add-on to standard-of-care, starting 3 months before TAVR and continuing for 24 months post-procedure. The primary endpoint is time to first occurrence of a composite of cardiovascular (CV) death, non-fatal myocardial infarction, non-fatal stroke or transient ischemic accident (TIA), and hospitalization for heart failure (HF). The study is event-driven and powered to detect a 20% relative risk reduction in primary outcome events. This trial aims to address the unmet need for medical therapies that improve outcomes in patients with severe AS following TAVR, with potential for direct clinical implementation.
