BIOLUX-RCT: Clinical Performance of the Pantera Lux Balloon Versus the Orsiro Stent in Patients With In-stent Restenosis.
Study Details
Study Description
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.

Detailed Description
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.
Study Design

Outcome Measures
Primary Outcome Measures
- Late lumen loss (in-stent) [After 6 months.]
In-stent late lumen loss is defined as the difference between minimal luminal diameter after procedure and at 6 months, as evaluated by offline quantitative coronary angiography (QCA). In-stent: Pantera Lux balloon: In-stent is defined as from (proximal) shoulder to (distal) shoulder of the dilated balloon. Orsiro stent: In-stent is defined as from (proximal) edge to (distal) edge of the implanted Orsiro stent.
Secondary Outcome Measures
- Percent diameter stenosis in-stent and in-segment [After 6 months.]
Percent diameter stenosis is defined as the difference between reference vessel diameter and minimal lumen diameter divided by reference vessel diameter x100%. Angiographic parameters as evaluated by offline QCA. In-segment: Pantera Lux balloon: In-segment is defined as in-stent plus 5 mm distal and 5 mm proximal. Orsiro stent: In-segment is defined as in-stent plus 5 mm distal and 5 mm proximal.
- Binary restenosis in-stent and in-segment [After 6 months.]
Binary restenosis is defined as ≥50% lumen diameter stenosis as evaluated by offline QCA.
- Mean lumen diameter in-stent and in-segment [After 6 months.]
Mean minimum lumen diameter derived from two orthogonal views as evaluated by offline QCA.
- Type of reoccurrence according to Mehran classification [After 6, 12 and 18 months.]
Type of reoccurrence according to Mehran classification (Mehran et al. Circulation 199; 100: 1872-1878) evaluated by offline QCA.
- Target lesion failure (TLF) [After 6 and 18 months.]
TLF is defined as a composite of cardiac death, any target vessel myocardial infarction (MI), coronary artery bypass graft (CABG) and clinically driven target lesion revascularization (TLR).
- Target vessel failure (TVF) [After 6, 12 and 18 months.]
TVF is defined as a composite of cardiac death, any target vessel myocardial infarction, coronary artery bypass graft and clinically driven target vessel revascularization (TVR).
- Stent thrombosis [After 6, 12 and 18 months.]
According to Academic Research Consortium (ARC) definition (Cutlip et al. Circulation 2007; 115: 2344-2351).
- Procedure success [During hospital stay or 7 days after procedure, whichever came first.]
Procedure success defined as achievement of a final diameter stenosis of <30% by QCA, using any percutaneous method, without the occurrence of death, MI, or repeat revascularization of the target lesion during the hospital stay or 7 days after procedure, whichever came first.
- Device success [1 day (During procedure)]
Successful delivery of the balloon or stent to the target lesion site in the coronary artery; and appropriate balloon inflation and deflation or stent deployment; and successful removal of the balloon or the delivery system.
