What this trial studies

This open-label, randomized study aims to evaluate the safety and efficacy of three different interventions for managing in-stent restenosis in patients with drug-eluting stents. The treatments being compared include the Magic Touch sirolimus-coated balloon, the Emperor paclitaxel and dextran-coated balloon, and the Xience chromium-cobalt everolimus-eluting stent. Patients will be enrolled based on their suitability for all three treatment options, and a subset may participate in an optical coherence tomography sub-study.

Who should consider this trial

Good fit: Ideal candidates are patients admitted for intervention of drug-eluting stent restenosis who meet the criteria for all three treatment arms.

Not a fit: Patients undergoing coronary angiography after sudden cardiac death or those who are pregnant or nursing may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients experiencing restenosis after coronary stent placement.

How similar studies have performed: Other studies have explored various interventions for stent restenosis, but this specific comparison of these three methods is relatively novel.
