COMPARE is the world’s first head-to-head prospective, RCT (1:1) comparing low dose Ranger DCB (2 μg/mm2) to higher dose IN.PACT DCB (3.5 μg/mm2).
Ranger demonstrated similar primary patency1 with half the total drug dose.2
24-Month Results Presented at LINC 2021 by Sabine Steiner, MD
Target Lesion Length = ~126 mm Total Occlusions = ~42% Moderate to Severe Calcium = ~54%

Definitions
Primary safety endpoint — composite of freedom from device and procedure-related death through 30-days and freedom from major target limb amputation and CD-TLR through 12 months post index-procedure.
Primary efficacy endpoint — primary patency at 12 months defined as absence of clinically-driven target lesion revascularization (CD-TLR) or binary restenosis determined as a peak systolic velocity ratio > 2.4 evaluated by duplex ultrasound core laboratory analysis.
CD-TLR — a reintervention performed for ≥ 50% diameter stenosis (confirmed by angiography) within ± 5 mm proximal and/or distal to the target lesion after documentation of recurrent clinical symptoms of PAD (increase of 1 Rutherford class or more) and/or drop of ABI (≥20% or ≥0.15 when compared to maximum early postprocedural level).
