Comparison of Agent™ and SeQuent® Please Paclitaxel Coated Balloon Catheters in Coronary In-stent Restenosis (AGENT-ISR)
- Conditions
- Coronary ArteriosclerosisCoronary Artery DiseaseCoronary RestenosisCoronary Atherosclerosis

- Device: SeQuent® Please Paclitaxel-coated BalloonDevice: Agent Paclitaxel-coated balloon
- Registration Number
- NCT02151812
- Lead Sponsor
- Hemoteq AG
- Brief Summary
The primary objective of this study is determine the safety and performance of the Agent™ Paclitaxel-Coated PTCA Balloon Catheter compared to the SeQuent® Please Paclitaxel-Releasing Coronary Balloon Catheter for the treatment of patients with narrowed previously-stented coronary arteries (in-stent restenosis).
The performance will be determined at six months post-procedure by quantitative coronary angiography (QCA) to measure Late Lumen Loss (LLL) in the re-opened stented segment. QCA results will be assessed by an independent, blinded angiographic core lab.
Study statistical hypothesis: The loss of in-stent luminal diameter at six months after treatment of the restenosed stent with the Agent™ study device is not larger than the respective LLL after treatment with the SeQuent® Please control devices, i.e. study device is non-inferior to the control device with respect to LLL.

- Primary Outcome Measures
Name Time Method in-stent late lumen loss six months In-stent late lumen loss (LLL) of the treated stented segment after PTCA using the Agent(TM) study device in comparison to the LLL after PTCA using the SeQuent(R) Please control device as measured by QCA at six months post-index procedure.
- Secondary Outcome Measures
Name Time Method technical success rate during index procedure, less 1 hour The ability to cross and dilate the lesion to achieve residual angiographic stenosis no greater than 30 percent

In-stent percent diameter stenosis 6 months post-index procedure In-stent percent diameter reduction measured within the borders of the stent
In-segment percent diameter stenosis 6 months post-index procedure In-segment percent diameter reduction measured in the stented segment plus 5mm on either side.
In-stent binary restenosis rate 6 months post-index procedure In-stent binary restenosis is defined as ≥50% luminal narrowing within the borders of the stent observed at follow-up QCA.
In-segment binary restenosis rate 6 months post-index procedure In-segment binary restenosis is defined as ≥50% luminal narrowing in the stented segment plus 5mm on either side observed at follow-up QCA.
In-segment late lumen loss 6 months post-index procedure In-segment late lumen loss is the in-segment minimal lumen diameter (MLD) post index procedure minus the in-segment MLD at 6 months follow-up as determined by QCA.
