Abstract
OBJECTIVES The aim of this randomized controlled trial was to investigate a novel sirolimus-coated balloon (SCB) compared with the best investigated paclitaxel-coated balloon (PCB). BACKGROUND There is increasing clinical evidence for the treatment of coronary de novo disease using drug-coated balloons. However, it is unclear whether paclitaxel remains the drug of choice or if sirolimus is an alternative, in analogy to drug-eluting stents. METHODS Seventy patients with coronary de novo lesions were enrolled in a randomized, multicenter trial to compare a novel SCB (SeQuent SCB, B. Braun Melsungen; 4 mu g/mm(2)) with a PCB (SeQuent Please, B. Braun Melsungen; 3 mu g/mm(2)). The primary endpoint was angiographic late lumen loss (LLL) at 6 months. Secondary endpoints included major adverse cardiovascular events and individual clinical endpoints such as cardiac death, target lesion myocardial infarction, clinically driven target lesion revascularization, and binary restenosis. RESULTS Quantitative coronary angiography revealed no differences in baseline parameters. After 6 months, in-segment LLL was 0.01 +/- 0.33 mm in the PCB group versus 0.10 +/- 0.32 mm in the SCB group. The mean difference between SCB and PCB was 0.08 (95% CI: -0.07 to 0.24). Noninferiority at a predefined margin of 0.35 was shown. However, negative LLL was more frequent in the PCB group (60% of lesions vs 32% in the SCB group; P = 0.019). Major adverse cardiovascular events up to 12 months also did not differ between the groups. CONCLUSIONS This first-in-human comparison of a novel SCB with a crystalline coating showed similar angiographic outcomes in the treatment of coronary de novo disease compared with a clinically proven PCB. However, late luminal enlargement was more frequently observed after PCB treatment.
