ILLUMENATE - ILLUMENATE
Contribution To Literature:
The ILLUMENATE trial shows that PTA with a paclitaxel-based DCB is superior to PTA with a regular balloon for primary patency in patients with short to moderately long femoropopliteal arterial lesions.
The goal of this trial was to assess safety and efficacy of a novel paclitaxel-coated balloon (2 mcg/mm2) compared with routine percutaneous transluminal angioplasty (PTA) in patients with femoropopliteal peripheral arterial disease.
Patients with superficial femoral artery (SFA) and/or popliteal arterial stenoses were randomized in a 2:1 fashion to balloon angioplasty with a drug-coated balloon (DCB) (n = 200) or standard balloon (n = 100).
- Rutherford class 2-4 symptoms
- Lesion in SFA and/or popliteal arteries
- Known intolerance to study medications, paclitaxel, or contrast agents that in the opinion of the investigator cannot be adequately pretreated
- Total number of enrollees: 300
- Duration of follow-up: 12 months
- Percentage female: 40%
- Percentage with diabetes: 50%
- Previous or current smokers: 80%
- Lesion characteristics: Mean lesion length, 85 mm; restenotic lesions, 15%; total occlusions, 20%; severe calcification, 44%; 0-1 patent run-off, 32%
The primary efficacy endpoint, clinically driven target lesion revascularization at 12 months for DCB vs. standard balloon, was 93.6% vs. 87.3%, p < 0.05.
Secondary endpoints for DCB vs. standard balloon, primary patency at 12 months, was 82.3% vs. 70.9%, p < 0.05.
The results of this trial indicate that PTA with a novel low-dose paclitaxel-coated balloon is superior to PTA with standard angioplasty alone in moderately long lesions in the SFA and/or popliteal arteries. These data are similar to the LEVANT 2 trial, which used a different balloon but the same drug (differences are in balloon design and dose of paclitaxel). Direct comparison of DCBs with drug-eluting stents is awaited. In the ZILVER-PTX trial with a PES, the rate of primary patency with PES was 83.1% at 1 year (mean lesion length 65 mm), compared with 82.3% in the current trial. Cost-effectiveness analyses are also awaited.
