    Abstract:
    OBJECTIVES: The aim of BIOLUX P-II (BIOTRONIK'S-First in Man study of the Passeo-18 LUX drug releasing PTA Balloon Catheter vs. the uncoated Passeo-18 PTA balloon catheter in subjects requiring revascularization of infrapopliteal arteries) trial was to compare the safety and efficacy of a novel paclitaxel-coated drug-eluting balloon (DEB) versus an uncoated balloon (percutaneous transluminal angioplasty [PTA]) in de novo or native restenotic lesions of the infrapopliteal arteries in patients with claudication and critical limb ischemia. BACKGROUND: DEB have shown promising results in femoropopliteal lesions, but data for infrapopliteal lesions are scarce. METHODS: In this prospective, multicenter, randomized first-in-man study, 72 patients were randomized 1:1 to either a Passeo-18 Lux DEB (Biotronik AG, Buelach, Switzerland) (n = 36) or Passeo-18 PTA (n = 36). Follow-up assessments were scheduled at 1, 6, and 12 months, with angiographic assessment at 6 months. Adverse events were adjudicated by an independent clinical events committee, and angiographic parameters were assessed by an independent core laboratory. RESULTS: The primary safety endpoint (a composite of all-cause mortality, target extremity major amputation, target lesion thrombosis, and target vessel revascularization at 30 days) was 0% in the DEB group versus 8.3% in the PTA group (p = 0.239). The primary performance endpoint (patency loss at 6 months) was 17.1% in the DEB group versus 26.1% in the PTA group (p = 0.298), and major amputations of the target extremity occurred in 3.3% versus 5.6% of the patients at 12 months, respectively. CONCLUSIONS: The Passeo-18 Lux DEB has been proven to be safe and effective in infrapopliteal lesions with comparable outcomes to PTA.
