- © 2022 The AuthorsBackground: Drug-coated balloons (DCBs) offer an effective treatment for in-stent restenosis (ISR). The Genoss DCB is a novel paclitaxel-coated balloon with a shellac plus vitamin E excipient that enhances drug delivery to the target lesion, minimizing restenosis. Objectives: This study aimed to investigate the angiographic efficacy, clinical safety, and effectiveness of the novel shellac plus vitamin E–based DCB in a randomized controlled trial designed to enable regulatory approval of this new device in South Korea. Methods: This noninferiority trial randomized patients experiencing their first ISR to the novel shellac plus vitamin E–based DCB or the reference SeQuent Please iopromide-based DCB in a 1:1 ratio. All patients underwent planned angiographic and clinical follow-up at 6 months. The study was powered for the primary endpoint of 6 months in-segment late lumen loss (LLL). Results: A total of 82 patients from 7 centers were randomized to either the novel shellac plus vitamin E–based DCB group (n = 41) or the reference iopromide-based DCB group (n = 41). The 6-month in-segment LLL was 0.15 ± 0.43 mm with the novel DCB compared with 0.24 ± 0.39 mm with the reference device. The 1-sided 97.5% upper confidence limit of the difference was 0.13 mm, lower than the noninferiority limit of 0.29 mm, achieving noninferiority (P for noninferiority = 0.001). Major cardiovascular events were comparable between 2 groups at 6 months (7.7% for the novel DCB vs 10.3% for the reference DCB; P = 0.692). Conclusions: In this multicenter, head-to-head comparison randomized trial, the novel shellac plus vitamin E–based DCB showed a comparable result to the reference iopromide-based device for the primary endpoint of 6-month in-segment LLL for the treatment of coronary ISR.
