This study sought to investigate safety and efficacy of biolimus-eluting stents (BES) with biodegradable polymer as compared with sirolimus-eluting stents (SES) with durable polymer through 2 years of follow-up.
BES with a biodegradable polymer provide similar efficacy and safety as SES with a durable polymer at 9 months. Clinical outcomes beyond the period of biodegradation of the polymer used for drug release and after discontinuation of dual antiplatelet therapy are of particular interest.
A total of 1,707 patients were randomized to unrestricted use of BES (n = 857) or SES (n = 850) in an all-comers patient population.
At 2 years, BES remained noninferior compared with SES for the primary endpoint, which was a composite of cardiac death, myocardial infarction, or clinically indicated target vessel revascularization (BES 12.8% vs. SES 15.2%, hazard ratio [HR]: 0.84, 95% confidence interval [CI]: 0.65 to 1.08, pnoninferiority < 0.0001, psuperiority = 0.18). Rates of cardiac death (3.2% vs. 3.9%, HR: 0.81, 95% CI: 0.49 to 1.35, p = 0.42), myocardial infarction (6.3% vs. 5.6%, HR: 1.12, 95% CI: 0.76 to 1.65, p = 0.56), and clinically indicated target vessel revascularization (7.5% vs. 8.6%, HR: 0.86, 95% CI: 0.62 to 1.20, p = 0.38) were similar for BES and SES. The rate of definite stent thrombosis through 2 years was 2.2% for BES and 2.5% for SES (p = 0.73). For the period between 1 and 2 years, event rates for definite stent thrombosis were 0.2% for BES and 0.5% for SES (p = 0.42). After discontinuation of dual antiplatelet therapy, no very late definite stent thrombosis occurred in the BES group.
At 2 years of follow-up, the unrestricted use of BES with a biodegradable polymer maintained a similar safety and efficacy profile as SES with a durable polymer. (Limus Eluted From a Durable Versus Erodable Stent Coating [LEADERS]; NCT00389220)
