RANGER-SFA: Comparison of the Ranger™ Paclitaxel-Coated PTA Balloon Catheter and Uncoated PTA Balloons in Femoropopliteal Arteries
Study Details
Study Description
Brief Summary
The primary objective of this study is to prove the superior performance of the Ranger™ paclitaxel-coated PTA balloon catheter for angioplasty for femoropopliteal artery lesions when compared to non-coated balloons at six months post-procedure when comparing Late Lumen Loss (LLL). Study statistical hypothesis: The %-mean loss of luminal diameter as assessed by angiography at six months follow-up after treatment of the femoropopliteal artery with Ranger DCB study devices is lower than the %-mean loss of luminal diameter after treatment with uncoated PTA balloon control devices.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Ranger(TM) Paclitaxel-coated balloon Index lesion treated with Ranger(TM) Paclitaxel-coated PTA balloon catheter (Ranger DCB) |
Device: Ranger DCB
After successful pre-dilatation the index lesion is treated with one or two Ranger DCB devices that completely cover the lesion. If two devices are deployed, overlap shall be minimal.
|
| Active Comparator: uncoated PTA balloon Index lesion treated with an uncoated standard PTA dilatation balloon catheter selected upon investigator´s discretion |
Device: uncoated PTA balloon
The index lesion is treated with one or more uncoated standard PTA balloons that completely cover the lesion.

Outcome Measures
Primary Outcome Measures
- in-segment late lumen loss [six months]
In-segment late lumen loss (LLL) of the treated segment after PTA using the Ranger™ paclitaxel-coated PTA balloon, in comparison to the LLL after PTA using an uncoated balloon, as observed by angiography at six months post-index procedure.
Secondary Outcome Measures
- technical success [during index procedure, less 1 hour]
The ability to cross and dilate the lesion to achieve residual angiographic stenosis no greater than 30%.
- procedural success [within 24 hours of index procedure]
Technical success with no MAE noted within 24 hours of the index procedure.
- primary patency [six months]
Percentage of lesions that reach endpoint without a hemodynamically significant stenosis on duplex ultrasound (DUS) and without target lesion revascularization (TLR) or bypass of the target lesion to maintain or restore patency.
- primary patency [twelve months]
Percentage of lesions that reach endpoint without a hemodynamically significant stenosis on DUS and without TLR or bypass of the target lesion to maintain or restore patency.
- assisted primary patency [six months]
Percentage of lesions without TLR and those with TLR (not due to complete occlusion or bypass) that reach endpoint without restenosis.
- assisted primary patency [twelve months]
Percentage of lesions without TLR and those with TLR (not due to complete occlusion or bypass) that reach endpoint without restenosis.
- secondary patency [six months]
