Abstract

Objectives: This study sought to determine clinical outcomes between treatment groups over long-term follow-up. Background: The safety and efficacy of a ridaforolimus-eluting stent (RES) was evaluated in the BIONICS (BioNIR Ridaforolimus-Eluting Coronary Stent System in Coronary Stenosis) and NIREUS (BioNIR Ridaforolimus Eluting Coronary Stent System [BioNIR] European Angiography Study) trials, demonstrating noninferiority of RES in comparison with a zotarolimus-eluting stent (ZES) regarding 1-year target lesion failure (TLF) and 6-month angiographic late lumen loss, respectively. Methods: Patient-level data from the BIONICS (N = 1,919) and NIREUS (N = 302) randomized trials were pooled, and outcomes in patients implanted with RES and ZES compared. Broad inclusion criteria allowed enrollment of patients with acute coronary syndromes and complex lesions. The primary endpoint was the 2-year rate of TLF or clinically driven target lesion revascularization. Results: A total of 2,221 patients (age 63.2 ± 10.3 years; 79.7% men) undergoing percutaneous coronary intervention with RES (n = 1,159) or ZES (n = 1,062) were included. Clinical and angiographic characteristics were similar between groups. At 2 years, the primary endpoint of TLF was similar among patients implanted with RES and ZES (7.0% vs. 7.2%; p = 0.94). Rates of target lesion revascularization (4.8% RES vs. 4.1% ZES; p = 0.41) and target vessel–related myocardial infarction (3.1% RES vs. 3.8% ZES; p = 0.52) did not differ between groups. The overall rate of stent thrombosis was also similar (0.5% RES vs. 0.9% ZES; p = 0.39). Conclusions: In a pooled analysis of 2 randomized trials, 2-year clinical outcomes were similar between patients undergoing percutaneous coronary intervention with RES and ZES. These results support the long-term safety and efficacy of RES for the treatment of a broad population of patients with coronary artery disease.
