Objectives
Based on a novel paclitaxel–resveratrol drug matrix, the safety and efficacy to inhibit intimal hyperplasia were studied in symptomatic claudicants with morphologically challenging lesions.
Background
The treatment of peripheral artery occlusive disease (PAOD) with percutaneous transluminal angioplasty is limited by occurrence of vessel recoil and neointimal hyperplasia. Drug-coated balloons (DCB) deliver drugs to the arterial wall to potentially reduce the restenosis rate. A number of paclitaxel-coated balloon technologies are available to treat peripheral lesions.
Methods
In this randomized controlled trial, a total of 153 patients with symptomatic PAOD in femoro-popliteal lesions were randomized either to DCB or plain old balloon angioplasty (POBA).
Results
The mean lesion length was 13.2 ± 10.4 cm with target lesion total occlusions in 26.1% of all patients (40/153). The primary endpoint of in-lesion late lumen loss (LLL) at 6 months was significantly reduced in the DCB group as compared to the POBA group (0.35 mm CI [0.19; 0.79 mm] vs. 0.72 mm CI [0.68; 1.22 mm], p = 0.006). At 12 months, the TLR rate in the DCB group was significantly lower as compared to the POBA group (17.8 vs. 37.7% p = 0.008). The censored walking distance increase suggests a benefit for patients who underwent DCB angioplasty as compared to the standard POBA treatment (12 months 165 ± 105 vs. 94 ± 136 m, p = 0.012).
Conclusion
The use of paclitaxel–resveratrol-matrix-coated peripheral balloon angioplasty as compared to POBA was associated with significantly reduced in-lesion LLL and reduced TLR rates.
