Rationale and design of amphilimus sirolimus-eluting stents versus zotarolimus-eluting stents in all-comers requiring percutaneous coronary intervention (ReCre8): A multicenter randomized clinical trial.

Background: Amphilimus sirolimus-eluting stents (A-SES) represent a novel elution technology in the current era of drug-eluting stents with promising results in patients with diabetes mellitus. At present no large trial has been designed to evaluate clinical outcomes of A-SES as compared to new-generation drug-eluting stents in unselected patients. Accordingly, we designed this trial to evaluate clinical noninferiority of A-SES as compared with zotarolimus-eluting stents (ZES) in a real-world, all-comers setting.

Study Design: ReCre8 is a prospective multicenter randomized clinical trial evaluating the clinical outcomes of A-SES as compared with ZES in all-comers requiring percutaneous coronary intervention. Patients are randomized 1:1 to receive either A-SES or ZES. On-site block-randomization is stratified by diabetes mellitus, and troponin status to perform prespecified subanalyses. Patients receive 1-month of dual antiplatelet therapy (DAPT) when troponin-negative, or 12-months of DAPT when troponin-positive. The primary endpoint is target-lesion failure at 1-year follow-up. A total of 1,532 patients will be enrolled to demonstrate clinical noninferiority of A-SES with at least 80% power, a noninferiority margin of 3.5% and a type-I-error of 0.05.

Conclusions: ReCre8 (NCT02328898) is the first randomized multicenter trial with a head-to-head comparison of A-SES as compared with ZES to investigate the clinical safety and efficacy of these new-generation DES in a real-world, all-comers population.
