Abstract

Objectives: The aim of this study was to assess the 2-year clinical outcomes of the Firehawk stent (Shanghai MicroPort Medical Group, Shanghai, China), a novel abluminal groove-filled biodegradable-polymer sirolimus-eluting coronary stent, compared with XIENCE (Abbott Vascular, Santa Clara, California), a durable-polymer everolimus-eluting coronary stent.

Background: The long-term outcomes of the Firehawk stent have not been evaluated beyond 1 year in a randomized all-comers clinical trial.

Methods: The TARGET All Comers study is a prospective, multicenter, all-comers, randomized, noninferiority trial conducted in Europe. A total of 1,653 patients were randomly assigned to undergo implantation of either the Firehawk or the XIENCE stent. The primary endpoint was target lesion failure, a composite of cardiac death, target vessel myocardial infarction, or ischemia-driven target lesion revascularization.

Results: At 2-year follow-up, the incidence of target lesion failure was 8.7% in the Firehawk group versus 8.6% in the XIENCE group (p = 0.92). The event rates of individual components of the primary endpoint were comparable for the 2 groups. Landmark analyses between 1- and 2-year follow-up revealed no statistically significant difference of TLF for the Firehawk versus the XIENCE stent. Beyond 1 year, very late definite or probable stent thrombosis occurred in 3 patients (0.4%) in the Firehawk group and in 7 patients (0.9%) in the XIENCE group (p = 0.34).

Conclusions: The 2-year follow-up of the TARGET All Comers study confirms comparable safety and efficacy profiles of the Firehawk and XIENCE stents.

Trial registration: ClinicalTrials.gov NCT02520180.
