Abstract

Drug-coated balloons (DCBs), developed to reduce restenosis after percutaneous intervention in peripheral arterial disease (PAD), have been shown to be safe and efficacious, particularly in treating PAD affecting the femoropopliteal segment. The SurVeil DCB uses an excipient intended to optimize both the uniformity and transfer of paclitaxel to the vessel wall, allowing for efficient drug loading and lower systemic exposure than currently available DCBs, Heretofore, clinical outcomes have not previously been compared to other DCBs. This prospective, multicenter, international, randomized, single-blind, trial will compare 1:1 the SurVeil DCB with the IN.PACT Admiral DCB for treatment of patients with Rutherford classification 2 to 4 due to femoral and/or popliteal arterial disease. The trial will randomize 446 subjects (with reference vessel diameter 4-7 mm and total lesion length ≤180 mm). Subjects will be followed for 60 months. The primary efficacy endpoint is 1 year primary patency, defined as composite freedom from clinically-driven target-lesion revascularization (TLR) and binary restenosis (core lab-adjudicated duplex ultrasound peak systolic velocity ratio ≥2.4, or ≥50% stenosis via angiography). The primary safety endpoint is composite freedom from device- and procedure-related death through 30 days and freedom from target limb major amputation and clinically-driven target vessel revascularization through 12 months. The primary analysis is a test of noninferiority of the SurVeil vs. IN.PACT Admiral on the primary efficacy and safety endpoints according to absolute deltas of 15.0% and 10.0%, respectively. The Randomized And Controlled Noninferiority Trial to Evaluate Safety and Clinical Efficacy of the SurVeil DCB in the Treatment of Subjects with Stenotic Lesions of the Femoropopliteal Artery Compared to the Medtronic IN.PACT Admiral (TRANSCEND) study will assess safety and efficacy of the SurVeil DCB relative to a commonly used DCB.
