Abstract

The aim of the BIOPAC trial was to determine long-term safety and efficacy of a novel microcrystalline paclitaxel-coated balloon (mcPCB) with a biocompatible polymer as an excipient in the treatment of occlusive femoropopliteal lesions. In this first-in-human prospective controlled randomized trial, 66 patients with femoropopliteal, symptomatic (Rutherford stages 2B to 5) occlusive arterial disease were randomized to either mcPCB (study group) or POBA (plain old balloon angioplasty) (control group) on a 1:1 basis. Late lumen loss (LLL) at 6 months was the primary endpoint of the study and serious adverse events (SAE: death, amputation, repeated revascularization) were considered a composite secondary endpoint. Routine angiography was scheduled for all study subjects at 6-month follow-up; outpatient appointments were scheduled at 12 and 36 months after intervention. At 6 months, the LLL was 63% lower in the mcPCB group compared to the POBA group (0.52 ± 1.2 vs 1.39 ± 1.1 mm; psup < 0.01). Binary restenosis occurred in 23% vs 52% of patients (p = 0.02). At 3 years, the prevalence of SAE was significantly lower in the mcPCB group (33.3 vs 63.3%; p = 0.02), which mainly resulted from a twofold reduction in target vessel revascularization rate (28.6 vs 59.3%; p = 0.02). The difference in mortality was nonsignificant (7.4 vs 14.3%; p = 0.42). Patients with mcPCB were less symptomatic and less likely to adhere to secondary prevention measures. In this pivotal trial, a novel mcPCB proved superior to POBA concerning LLL at 6-month follow-up, and SAE at 12 months. This result was sustained up to 3 years. There was no difference between groups regarding mortality. ClinicalTrials.gov Identifier: NCT02145065
