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).
Target Lesion Length = ~126 mm Total Occlusions = ~42% Moderate to Severe Calcium = ~54%
|12-MONTH PRIMARY ENDPOINTS||RANGER||IN.PACT||p-value|
|Binary Primary Patency||83.0%
|Freedom from major adverse events||91.0%
|Both primary endpoints met.|
|Excipient||TransPax™ citrate ester||Urea||N/A|
|Paclitaxel dose density||2.0 µg/mm2||3.5 µg/mm2||N/A|
|Average total paclitaxel dose per patient in trial||6,971 µg||13,035 µg||<0.0001|
|Total Occlusion Length||131 mm||113 mm||0.23|
|Target Lesion Length||124 mm||128 mm||0.65|
|Moderate to Severe Calcification**||51%||57%||***|
|* p-value based on entire distribution. Never, Former or Current Smokers
** PACSS Grade 3/4 may be considered similar to moderate/severe calcification
*** p-value for entire distribution of PACSS Calcium Grades 0, 1, 2, 3, 4 calcium for RANGER vs IN.PACT. p-value was 0.20.

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).
