BackgroundThe Cobra-P drug-eluting stent (DES) system consists of cobalt chromium alloy with bio-absorbable siloxane sol–gel matrix coating that elutes low dose paclitaxel within 6 months. The aim of this first-in-man trial was to evaluate the safety and performance of 2 doses of the Cobra-P DES.MethodsA total of 60 lesions (54 patients) were sequentially assigned to 2 different paclitaxel doses: group A (3.7 μg/18 mm, n = 30) or group B (8 μg/18 mm, n = 30). The primary endpoint was MACE at 4 months defined as cardiac death, myocardial infarction, and target lesion revascularization.ResultsPatient and lesion characteristics were matched between the 2 groups except for male sex. MACE at 4 months was 3.3% and 0% respectively (P = 1.000) and at 1-year follow-up remained unchanged. In-stent late loss at 4 months was similar in both groups (0.36 ± 0.30 mm and 0.34 ± 0.20 mm P = .773).ConclusionsIn this FIM study, implantation of the Cobra-P low dose paclitaxel-eluting stent with a bioabsorbable sol–gel coating was proven to be feasible and safe. Moderate neointimal proliferation was observed as well as an acceptable MACE rate up to 1 year.
