BACKGROUND: BioFreedom is a polymer- and carrier-free drug-coated stent that delivers Biolimus A9 to the vessel wall. Our purpose was to evaluate the efficacy and safety of this DCS in patients with short-duration dual antiplatelet therapy.
CONCLUSIONS: This study's angiography and IVUS assessments demonstrated that the BioFreedom DCS has anti-restenotic efficacy similar to first-generation DES. In the absence of concerning safety signals, this DCS should be considered effective and safe for patients who require a shorter duration of DAPT. Copyright (c) 2017 Elsevier Inc.

METHODS: The BioFreedom US IDE feasibility trial was a single-arm, open-label, prospective study of patients requiring stenting of de novo lesions. Patients received 3 months of DAPT, repeat angiography at 9 months, and clinical follow-up at multiple intervals. A subgroup also underwent intravascular ultrasound (IVUS) interrogation. The primary safety end point was major adverse cardiac events, defined as a composite of cardiac death, myocardial infarction, target lesion revascularization, or stent thrombosis. The primary efficacy end point, in-stent late lumen loss at 9 months, was compared with a historical control from a first-generation paclitaxel-eluting stent.
RESULTS: A total of 72 patients from 10 sites received BioFreedom DCS implanted in 83 de novo lesions. At 9 months, the incidence of composite MACE was 8.4%, and TLR was 1.5%. Short DAPT was safe without occurrence of stent thrombosis. The primary end point of LLL was 0.32+/-0.53 mm. Paired IVUS analyses comparing postprocedural with 9-month measurements showed low in-stent neointimal volume obstruction (5.39+/-5.28%) and low neointimal hyperplasia (7.43+/-8.04 mm<sup>3</sup>).
