BACKGROUND: To assess the efficacy and safety of Orchid drug-coated balloon (DCB) for treatment of femoropopliteal (FP) artery in-stent restenosis (ISR) in Chinese patients.
METHODS: The study is a prospective, single center, single-blinded, randomized controlled trial (RCT) that randomized (1:1) 74 patients to DCB group (N.=38) and PTA group (N.=36). The primary efficacy endpoint was primary patency of the target lesion at 12 months. Second efficacy endpoint included clinically-driven target-lesion revascularization (CD-TLR) and ABI change at 12 months. The primary safety endpoint included peri-operative death at 30 days, all-cause death, major amputation, and other major adverse events (MAEs) at 12 months. The primary functional endpoint included Walking Impairment Questionnaire (WIQ), quality-of-life measures (EQ-5D) and 6-minute walking test (6MWT).
RESULTS: The DCB group had higher primary patency (87.9% vs. 51.6%; P=0.001) and lower rates of CD-TLR (6.1% vs. 35.5%; P=0.003) than the PTA group at 12 months. There were no peri-operative deaths, and no major amputations at 12 months in two groups. There were 1(2.6%) in the DCB group and 2 (5.6%) in the PTA group of all-cause deaths (P=0.524).
CONCLUSIONS: Results from the study showed superior treatment effect with Orchid DCB versus PTA for the treatment of FP ISR, and without an apparent difference in safety.
