Further study details as provided by Klinikum Rosenheim:

Primary Outcome Measures:
  • Late Lumen Loss (LLL) [ Time Frame: 6 +/-2 months ]
    • Late lumen loss (difference between the angiographic minimum lumen diameter (MLD) immediately and at 6 months post index procedure) evaluated by quantitative angiography. Analysis will be performed by an independent Angiographic Core Laboratory

Secondary Outcome Measures:
  • • Procedural success [ Time Frame: after intervention ]
    • Procedural success defined as ≤ 30% residual stenosis following the procedure at the target lesion (after prolonged dilation and stenting, if necessary)

  • Target lesion revascularization (TLR) [ Time Frame: 6, 12 and 24 months ]
    • Clinically-driven target lesion revascularization (TLR) at 6, 12 and 24 months. Target lesion revascularization is defined as any reintervention or artery bypass graft surgery involving the target lesion.

  • Target vessel revascularization (TVR) [ Time Frame: 6, 12 and 24 months ]
    • Target vessel revascularization (TVR) at 6, 12 and 24 months

  • Binary restenosis rate [ Time Frame: 6, 12 and 24 months ]

    • Binary restenosis rate at 6, 12 and 24 months.

    o Binary restenosis defined as > 50% diameter stenosis via angiography or PVR ≥ 2.4 via duplex ultrasound. In cases where results are available for both angiography and duplex ultrasound, angiographic results (if conducted within follow-up window) will be used to determine binary restenosis

  • Rutherford category [ Time Frame: 6, 12 and 24 months ]
    Change of Rutherford category post index procedure and at 6, 12, and 24 months as compared to baseline

  • Ancle Brachial index (ABI) [ Time Frame: 6, 12 and 24 months ]
    • Change in ABI at 6, 12, and 24 months as compared to baseline

  • Late lumen loss (LLL) [ Time Frame: 24 months ]
    • LLL at 24 months

  • Minimum lumen diameter (MLD) [ Time Frame: 12 and 24 months ]
    • MLD at 12 and 24 months

  • Hospitalization [ Time Frame: 6, 12 and 24 months ]
    • Hospitalization (extra days due to complications of the index procedure) and hospitalization between the follow-up visits due to the index lesion and index leg

  • safety [ Time Frame: 30days ]
    • Evaluation of 30 days freedom from procedure related death, unplanned amputation, and TLR.

  • resteosis pattern [ Time Frame: 6 and 24 months ]
    • Characterization of restenosis patterns between the two therapies

  • Target lesion revascularization (TLR), clinical success and angiographic outcome (restenosis rate, late lumen loss) after second therapy [ Time Frame: after intervention, 6, 12 and 24 months ]
    clinical success, restensosis, TLR and LLL after second use of drug eluting balloons if initial therapy failed 30 days or later

Inclusion Criteria:

  1. In-stent restenosis or re-occlusion at the target lesion due to an interventional treatment > 3 months prior to enrollment.
  2. Has evidence of ≥ 70% stenosis or occlusion in the SFA and/or popliteal confirmed by angiography that is 3-27 cm long.
  3. Reference vessel diameter of 3 to 7 mm (reference vessel diameter = normal vessel diameter 1 cm proximal of the index lesion)
  4. Patients (men and women) with PAD disease category 2 to 5 according to Rutherford classification.
  5. Patient is eligible for an operative vascular intervention in case of complications during the procedure.
  6. Female patients of child bearing potential must have a negative pregnancy test 7 days at theprior to the time of intervention.
  7. Fully informed and signed consent must be obtained from each patient.
  8. Patients must be willing and able to continue study participation following study procedure in order to ensure completion of all procedures and observations required by protocol.
  9. Patient has evidence of at least one run off vessel that does not also require treatment for significant (≥ 50% stenosis or occlusion) stenosis during the index procedure to the ankle/foot of the limb to be treated. Treatment of infrapopliteal lesions must be staged at least 30 days before or after the index procedure.
  10. If restnosis occurs in both arms 30 days or later (re-re-sternosis)- treament with two drug eluting balloons at the same location (double dose)

Exclusion Criteria:

  1. Patients with more than two lesions in the target vessel requiring treatment (if the distance between two lesions is less than 2 cm, the lesions should be counted as one lesion). The second lesion should also be treated with either coated or uncoated balloons (according to the randomization)
  2. Guidewire cannot cross lesion and/or an intentional subintimal approach in the stented lesion is required.
  3. Patients with stent fractures grade 2-4.
  4. Inflow lesion (proximal to the study lesion) with flow limitation not being successfully treated prior to treatment of the study lesion.
  5. Acute thrombosis of the study lesion requiring lysis or thrombectomy prior to the treatment of the study lesion.
