4-LB: Substantial Cardiovascular Benefit from Icosapent Ethyl in Patients with Diabetes: REDUCE-IT DIABETES

Background: Statin-treated patients with diabetes mellitus (DM) are at high cardiovascular (CV) risk. Methods: In REDUCE-IT, icosapent ethyl (IPE; 4 g/day) reduced CV risk vs. placebo in statin-treated patients with either DM plus risk factors or established CV disease. The primary endpoint was CV death, myocardial infarction (MI), stroke, coronary revascularization, or unstable angina. The key secondary endpoint was CV death, MI, or stroke. Key DM analyses were prespecified. Results: 58.5% of patients had DM; 91.0% on ≥1 DM medication, 49.5% on ≥2. IPE reduced primary (Figure) and key secondary first and total (first plus recurrent) events. Patients with and without DM both showed substantial benefits, but patients with DM had 1.5-fold greater rates of the primary endpoint in the placebo group, and a 7% absolute risk reduction in first and a 12.7% reduction in total events (both p Conclusion: IPE 4 g/day provides robust CV benefits in statin-treated patients with DM, with large relative and absolute risk reductions in both first and total CV events.
