A randomized comparison of two paclitaxel-coated balloons for the treatment of in-stent restenosis: The LONGTY ISR China randomized trial (LONGTY DCB vs. SeQuent Please DCB).
2021
Objectives This study sought to compare the efficacy and clinical safety of the LONGTY drug-coated balloon (DCB) with those of SeQuent Please DCB in patients with in-stent restenosis (ISR). Background Although DCB technologies have evolved, little is known about the clinical efficacy of the new-generation LONGTY DCB. Methods This was a prospective, multicenter, randomized, noninferiority trial comparing LONGTY DCB with SeQuent Please DCB in patients with ISR. The primary endpoint was target lesion late lumen loss at 9 months' follow-up. Results A total of 211 patients with ISR from 13 Chinese sites were included (LONGTY DCB, n = 105; SeQuent Please DCB, n = 106). Device success was achieved in all patients. At the 9 month angiographic follow-up, target lesion late lumen loss was 0.35 ± 0.42 mm with LONGTY and 0.38 ± 0.45 mm with SeQuent Please (p for noninferiority Conclusions In this multicenter, head-to-head, randomized trial, the new-generation LONGTY DCB was noninferior to the SeQuent Please DCB for the primary endpoint of target lesion late lumen loss at 9 months.
