    Abstract:
    OBJECTIVES: We aimed to evaluate the safety and effectiveness of the novel abluminal groove-filled biodegradable polymer-coated sirolimus-eluting FIREHAWK stent (MicroPort Medical, Shanghai, China) in a large cohort of patients. BACKGROUND: Trials on the FIREHAWK stent allowing targeted sirolimus release were not individually powered to reliably estimate low-frequency safety endpoints such as stent thrombosis (ST) or to examine long-term safety and efficacy. Additionally, the China Food and Drug Administration requires an objective performance criterion (OPC) study for new drug-eluting stents. METHODS: The primary endpoint, target lesion failure (TLF), was defined as the composite of cardiac death, target vessel myocardial infarction (MI), or clinically indicated target lesion revascularization at 12 months. Patient-level data from 1,007 patients with de novo native coronary lesions exclusively treated with the FIREHAWK stent in the TARGET serial studies (I and II) were prospectively collected, pooled and analyzed throughout a 2-year follow-up. RESULTS: The 12-month rate of TLF in 1,003 patients (follow-up rate, 99.6%) was 3.9% (upper 95% confidence interval (CI): 5.3%), which was significantly lower than the performance goal of 9.0% (P < 0.0001). The 24-month rates of TLF, PoCE (a composite of all-cause death, all MI, or any revascularization), and ARC definite or probable ST were 4.6%, 7.8% and 0.1%, respectively. In subgroup analysis, long lesion (≥ 30 mm) was an independent predictor of TLF within 2 years (hazard ratio [95%CI]: 2.44 [1.32, 4.53], P < 0.01). CONCLUSIONS: This pooled, patient-level analysis indicates that the FIREHAWK stent exhibits a promising 2-year efficacy and safety profile.
