Objective of the REAL PTX trial is to compare paclitaxel-eluting stents to paclitaxel-eluting balloons for treating symptomatic peripheral artery disease of the femoropopliteal artery.
The REAL PTX trial has been designed as prospective, randomized, multi-center, post-market study investigating the effect of the paclitaxel-eluting stent Zilver® PTX® (DES)in comparison to the use of a paclitaxel eluting balloon (DEB)in treating symptomatic peripheral artery disease of the femoropopliteal artery. Up to 150 patients will be enrolled in Germany and Belgium. Enrollment is expected to be completed within approximately six months of initiating the study. One group (DES or DEB) will be considered to yield significantly better results of the primary patency rate than the other group at 12 months follow up.

Peak Systolic Velocity Ratio (PSVR)
The primary outcome will be the one-year primary patency rate (Kaplan-Meier estimate at 12 months).Primary patency is defined as absence of clinically-driven target lesion revascularization (TLR) or binary restenosis. Binary restenosis is defined as a peak systolic velocity ratio (PSVR) \> 2.4 as evaluated by duplex ultrasound core laboratory analysis.
Time frame: 12 months
target lesion revascularization (TLR)
The primary outcome will be the one-year primary patency rate (Kaplan-Meier estimate at 12 months).Primary patency is defined as absence of clinically-driven target lesion revascularization (TLR) or binary restenosis. Binary restenosis is defined as a peak systolic velocity ratio (PSVR) \> 2.4 as evaluated by duplex ultrasound core laboratory analysis.
Time frame: 12 months
Major Adverse Events (MAEs)
MAE is defined as: * Death within 30 days of the index procedure or within 30 days of a target lesion revascularization (TLR) * Clinically-driven TLR, or * Major target limb amputation.
Time frame: 6, 12 and 24 months
All cause death
Time frame: 6, 12 and 24 months
Target vessel revascularization (TVR)
Time frame: 6, 12 and 24 months
Clinically-driven target lesion revascularization (TLR)
Clinically-driven TLR is defined as a reintervention performed for ≥ 50% diameter stenosis (confirmed by angiography) within ± 5 mm proximal and/or distal to the target lesion after documentation of recurrent clinical symptoms of peripheral artery disease (PAD) following the initial procedure.
Time frame: 6, 12 and 24 months

Major target limb amputation within 6, 12 and 24 months. Major target limb Major target limb amputation
Major target limb amputation is defined as amputation of the target leg other than amputation of the toe(s).
Time frame: 6, 12 and 24 months
Sustained clinical improvement
Sustained clinical improvement is defined as an improvement in the Rutherford category of one class compared to baseline in surviving patients who are free from major target limb amputation and free from target lesion revascularization (TLR).
Time frame: 6, 12 and 24 months
Binary restenosis
Binary restenosis (Peak Systolic Velocity Ratio (PSVR) \>2.4)of the target lesion at 6, 12 and 24 months or at the time of reintervention prior to any pre-specified time point.
Time frame: 6, 12 and 24 months
Walking capacity
Walking capacity assessment by walking impairment questionnaire (WIQ) at 6, 12 and 24 months or at the time of reintervention prior to any pre-specified time point.
Time frame: 6, 12 and 24 months
Procedural success
Procedural success is defined as obtainment of \< 30% residual stenosis on angiography by visual estimate.
Time frame: 6, 12 and 24 months
