LISBON -- Extended-release exenatide (Bydureon) was safe for the heart but didn't help prevent cardiovascular events in type 2 diabetes among a mixed primary and secondary prevention population, the EXSCEL trial showed.
For the primary composite endpoint of death from cardiovascular causes, nonfatal myocardial infarction, or nonfatal stroke, the once-weekly GLP-1 diabetes drug fell just short of showing a cardiovascular benefit, Rury Holman, FRCP, of the Diabetes Trials Unit at the University of Oxford in England, and colleagues reported here at the European Association for the Study of Diabetes meeting and in a paper published simultaneously in the New England Journal of Medicine .
Note that this large, pragmatic randomized trial failed to demonstrate that extended release exenatide was superior to placebo in terms of cardiac outcomes among patients with type 2 diabetes.
This stands in contrast to trials with certain other agents in the GLP-1 class, which showed beneficial cardiovascular effects.
Rates for the composite after median follow-up of 3.2 years were 11.4% with the drug versus 12.2% with placebo (HR 0.91, 95% CI 0.83-1.00), each used along with usual care. That translated to noninferiority for safety (P<0.001 for noninferiority) but missed superiority for efficacy (P=0.06 for superiority), as had been annou
