Study population

Patient population for this study are patients with a diminished blood flow in their heavily calcified femoropopliteal lesions, who need a reintervention.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Subject must be between 21 and 85 years old

  • Willing to comply with the specified follow-up evaluation
  • Written prior to any study procedures
  • Stenotic, restenotic after PTA or occlusive lesion(s) located in the native Superficial Femoral Artery (SFA) and/or proximal Popliteal Artery (PPA):

    1. Degree of stenosis ≥ 70% by visual agiographic assessment
    2. Vessel diameter ≥ 4 and ≥ 6 mm
    3. Total lesion length (or series of lesions) ≥ 30 mm and 210 mm (Note: Lesion segment(s) must be filly covered with one or two overlapping DES stent (s) be fully covered with one or two overlapping DES stent(s)

  • Study entry after successful target lesion crossing of the guidewire (guidewire located intraluminally or subintimally); Both crossing devices as well as retrograde recanalization can be used.
  • Non-target lesion interventions to restore adequate blood flow, in the same index procedure are allowed. This intervention must be prior to the treatment of the study lesion and should be completed successfully.

Exclusion criteria

Exclusion Criteria:

  • Not treated ipsilateral significant (>50%) stenosis of the iliac arteries

  • End-stage-renal disease
  • Presence of Severe Ischemic Ulcers or frank gangrene (Rutherford class 6).
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

What researchers measure

Primary outcomes

  1. Primary Patency

    Defined as a target lesion without a hemodynamically significant stenosis on duplex ultrasound (\>50%, systolic velocity ratio no greater than 2.4) and without Target Lesion Revascularization (TLR)

    Time frame: 12 months

  2. Procedural success:

    Defined as technical success and completion of the procedure without complications , meaning successful treatment of the vessels (technical success) in the absence of: * vessel rupture or perforation that require an intervention * need for emergency surgical revascularization of target limb * symptomatic thrombus or distal emboli that require surgical, mechanical, or pharmacologic means to improve flow and extend hospitalization * unplanned above the ankle amputation * major adverse cardiovascular events (defined as composite of total death, myocardial infarction, coronary revascularization and stroke).

    Time frame: 30 days post procedure

Secondary outcomes

  1. Primary Patency

    Defined as a target lesion without a hemodynamically significant stenosis on duplex ultrasound (\>50 systolic velocity ratio no greater than 2,4) and without Target Lesion Revascularization (TLR)

    Time frame: 6 months

  2. Target Lesion Revascularization (TLR)

    Defined as the need for target lesion revascularization after index procedure.

    Time frame: 6- and 12-months

  3. Secondary Patency Rate

    Defined as restored flow in the treated segment after occlusion or restenosis.

    Time frame: 6- and 12-months

  4. Amputation-free Survival rate

    Defined as the time until a major amputation of the index limb and/or death of any cause, whichever occurred first.

    Time frame: 6- and 12-months

  5. Major Amputation Rate

    Defined as any aboveankle amputation.

    Time frame: 6- and 12-months

  6. Clinical Success

    Defined as an improvement of the Rutherford Becker Classification of one class or more, as compared to the preprocedure Rutherford Becker Classification.

    Time frame: 6- and 12-months

  7. Absence of Major Adverse Events (MAE)

    Acute Coronary Syndrome, Stroke, Death, Major Amputation or TLR.

    Time frame: 6- and 12-months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2022 to primary completion in Sep 2025, 38 months.

Of 138 non-industry observational studies under Peripheral Arterial Disease, half reached primary completion within 40 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 116. This study's 38 months is close to that.

Counting every sponsor, half of 196 studies reached it within 36 months; a quarter within 22 and three quarters within 73.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 27, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
