Official Title  ICMJE BIOLUX RCT - Clinical Performance of the Pantera LUX Paclitaxel Releasing Balloon Versus the Drug Eluting Orsiro Hybrid Stent System in Patients With In-stent Restenosis - a Randomized Controlled Trial
Brief Summary To determine in a randomized controlled trial (RCT) whether percutaneous coronary intervention - in patients with in-stent restenosis in either bare metal stents or drug eluting stents - with the Pantera Lux balloon is angiographically non-inferior to percutaneous intervention with the Orsiro stent 6 months post-procedure.

This clinical investigation is an international, multi-center, randomized controlled trial with angiographic follow up at 6 months. Clinical follow ups will take place at 6, 12 and 18 months.

Up to 210 subjects will be block randomized 2:1 to receive the Pantera Lux balloon or the Orsiro stent and will be stratified according to diabetic status at screening.
