SURPASS-CVOT and Tirzepatide, a Dual GIP/GLP-1 RA, in ASCVD

Don't Miss a Beat

About
In this episode of Don’t Miss a Beat, hosts Stephen Greene, MD, and Muthiah Vaduganathan, MD, MPH, sit down with Darren McGuire, MD, to explore the groundbreaking results of the SURPASS-CVOT trial. This cardiovascular outcome study is the first to directly compare two incretin-based therapies—tirzepatide, a dual GIP/GLP-1 receptor agonist, and dulaglutide, a GLP-1 receptor agonist—among patients with type 2 diabetes and established atherosclerotic cardiovascular disease (ASCVD). Unlike the placebo-controlled GLP-1 programs of the past decade, SURPASS-CVOT represents a pivotal move toward active comparator trials in cardiometabolic medicine.
