Brief Summary:

This study is a prospective, interventional, multi-center 1:1 randomized non-inferiority trial.

The trial evaluates the safety and efficacy of the Magic Touch PTA sirolimus drug-coated balloon in comparison to the treatment with PTX drug-coated balloon (control device) in patients with femoropopliteal artery disease.

Condition or disease Intervention/treatment Phase
Peripheral Artery Disease Combination Product: Percutaneous Transluminal Angioplasty (PTA) Not Applicable

Detailed Description:

Percutaneous transluminal angioplasty (PTA), in which a balloon is advanced and inflated in the obstructed artery for several seconds to minutes, has become the standard endovascular treatment for peripheral arteries. The long-term success of bare balloon PTA in the fem-oropopliteal segment is hampered by the occurrence of restenosis, which can be reduced by local antiproliferative drug delivery via the PTA balloon catheter.

The rationale of this study is based on the hypothesis that the usage of the Sirolimus-coated Magic Touch Sirolimus DCB is at least equal (non-inferior) with regards to efficacy and safety in comparison with a clinically well-established PTX coated balloon.

The objective of this prospective, randomized, multi-center, post-market study is to compare the Magic Touch Sirolimus DCB with Paclitaxel-coated DCB for treatment of high grade ste-notic or occluded lesions in SFA and / or P1 segment of the popliteal artery (PA) in PAD pa-tients.

PTA with an drug-coated balloon catheter (DCB) in the femoropopliteal artery

Primary Outcome Measures :
  1. Patency rate (Absence of clinically driven target lesion revascularization) [ Time Frame: one year after study procedure (PTA with medical product under investigation or comparator) ]
    patency rate after one year defined as absence of clinically driven target lesion revascularization (TLR) due to symptoms and drop of ABI of ≥ 20% or > 0.15 when compared to post-procedure or restenosis with PVR > 2.4 evaluated by duplex ultrasound

  2. Safety outcome [ Time Frame: through 12 months post-procedure ]
    Composite of freedom from device and procedure-related death through 12 months post procedure as well as freedom from both target limb major amputation and clinically-driven target vessel vessel revasculariza-tion

Secondary Outcome Measures :
  1. TLR rate [ Time Frame: 1, 6, 12, 24, 36, 48 and 60 months after study procedure ]
    ocurrence of Target lesion revascularization (TLR) at certain time Points

  2. Rutherford classification [ Time Frame: at 12 months after study procedure ]
    Sustained clinical improvement: an improvement shift in the Rutherford classification of one class in amputation and TVR free surviving patients

  3. Walking capacity assessment 1 [ Time Frame: at 1, 6, 12, 24, 36, 48 and 60 months after study procedure ]
    patient-self-assessment of walking distance

  4. Walking capacity assessment 2 [ Time Frame: at 6, 12, 24, 48 months after study procedure ]
    6-minute Walking test (6MWT)

  5. Walking capacity assessment 3 [ Time Frame: at 6, 12, 24, 48 months after study procedure ]
    Treadmill test (optional)

  6. Walking capacity assessment 4 [ Time Frame: at 6, 12, 24, 48 months after study procedure ]
    Walking Impairment Questionnaire (WIQ); 20 questions (scale 0 to 4); best score 0, worst score 80

  7. Duplex Ultrasound [ Time Frame: post-procedure and at 6, 12, 24 and 48 months or at any time of re-intervention ]
    Duplex-defined binary restenosis (PSVR >2.4) of the target lesion

  8. ABI [ Time Frame: at discharge, 6, 12, 24 and 48 months ]
    Ankle brachial index (ABI)

  9. Qualilty of Life Assessment [ Time Frame: at 1 month, 6, 12, 24, 36, 48 and 60 months ]
    Quality of life assessment (QoL) by EQ5D-3L questionnaire; 5 questions (scale 1 to 5), best score 5, worst score 25

  10. Secondary Safety: freedom from all cause death, target limb major amputation and clinically-driven target vessel revascularization [ Time Frame: trough 60 months after study procedure ]
    Composite of freedom from all cause death through 60 months post procedure as well as freedom from both target limb major amputation and clinically-driven target vessel revascularization
