Abstract

OBJECTIVES:

The aim of the present study was to evaluate the angiographic efficacy, clinical safety, and effectiveness of the Restore paclitaxel-coated balloon in a randomized trial designed to enable the approval of the new device in China.

BACKGROUND:

Drug-coated balloon (DCB) angioplasty offers an effective treatment for in-stent restenosis. Restore is a new DCB with a SAFEPAX shellac-ammonium salt excipient that can avoid drug washing off during catheter delivery to the target lesion site.

METHODS:

In the noninferiority RESTORE ISR China (Compare the Efficacy and Safety of RESTORE DEB and SeQuent Please in Chinese Patient With Coronary In-stent Restenosis) trial, eligible patients with first occurrence of drug-eluting stent ISR were randomized to the Restore DCB or SeQuent Please DCB in a 1:1 ratio stratified by diabetes. Angiographic and clinical follow-up was planned at 9 months and 1 year, respectively, in all patients. The study was powered for the primary endpoint of 9-month in-segment late loss.

RESULTS:

Between May 2016 and July 2017, a total of 240 subjects at 12 sites were randomized to either the Restore group (n = 120) or the SeQuent Please group (n = 120). Nine-month in-segment late loss was 0.38 ± 0.50 mm with Restore versus 0.35 ± 0.47 mm with SeQuent Please; the 1-sided 97.5% upper confidence limit of the difference was 0.17 mm, achieving noninferiority of Restore compared with SeQuent Please (p for noninferiority = 0.02). Both DCBs had similar 1-year rates of target lesion failure (13.3% vs. 12.6%; p = 0.87).

CONCLUSIONS:

In this head-to-head randomized trial, the Restore DCB was noninferior to the SeQuent Please DCB for the primary endpoint of 9-month in-segment late loss. (Compare the Efficacy and Safety of RESTORE DEB and SeQuent Please in Chinese Patient With Coronary In-stent Restenosis; NCT02944890).
