Tóm tắt

 BACKGROUND: The randomized Chocolate Touch Study demonstrated that in patients undergoing treatment of femoropopliteal artery lesions, the Chocolate Touch drug-coated balloon (DCB) was safe and had superior efficacy at 12 months compared with the Lutonix DCB. We report the prespecified diabetes subanalysis comparing outcomes among patients with and without diabetes mellitus (DM). METHODS: Patients with claudication or ischemic rest pain (Rutherford class 2-4) were randomized to Chocolate Touch or Lutonix DCB. The primary efficacy endpoint was DCB success defined as primary patency at 12 months (peak systolic velocity ratio <
 2.4 by duplex ultrasound without clinically driven target lesion revascularization in the absence of bailout stenting). The primary safety endpoint was freedom from major adverse events at 12 months, a composite of target limb-related death, major amputation, or reintervention. RESULTS: A total of 313 patients (38% DM [n=119]) were randomized to either Chocolate Touch (n=66/152) or Lutonix DCB (n=53/161). Among patients with DM, DCB success was 77.2% and 60.5% (p=0.08), and in non-DM patients, DCB success was 80% and 71.3% (p=0.2114) for the Chocolate Touch and Lutonix DCB, respectively. The primary safety endpoint was similar for both cohorts regardless of DM status (interaction test, p=0.96). CONCLUSIONS: This randomized trial demonstrated similar safety and efficacy for the treatment of femoropopliteal disease with the Chocolate Touch DCB compared with using the Lutonix DCB regardless of DM status at 12 months.Clinical ImpactThis substudy of the Chocolate Touch Study demonstrated similar safety and efficacy for treatment of femoropopliteal disease of the Chocolate Touch DCB compared with the Lutonix DCB regardless of diabetes (DM) status at 12 months. Endovascular therapy has become the therapy of choice for the treatment of most symptomatic femoropopliteal lesions regardless of DM status. These results give clinicians another option when treating femoropopliteal disease in this high-risk patient population.
