  4. Six-minute Walking Distance

    The Six-minute Walking Distance test is an objective method for estimation of walking capacity in patients with Peripheral Arterial Disease (PAD) or claudication.

    Measured: 1 Year

Secondary outcomes (16)
  1. Number of Participants Experiencing Peri-procedural and Post-procedural Complications

    Periprocedural/Postprocedural Complications defined as complications during the procedure through 30 days post implant that include hematoma, arteriovenous (AV) fistula pseudoaneurysm, subacute occlusion, non-target lesion Percutaneous Transluminal Angioplasty (PTA) /stenting, distal embolization, and vessel perforation.

    Measured: 30 days

  2. Number of Peri-procedural and Post-procedural Complications

    Periprocedural/Postprocedural Complications defined as complications during the procedure through 30 days post implant that include hematoma, arteriovenous (AV) fistula pseudoaneurysm, subacute occlusion, non-target lesion Percutaneous Transluminal Angioplasty (PTA) /stenting, distal embolization, and vessel perforation.

    Measured: 30 days

  3. Rutherford-Becker Clinical Category

    Rutherford/Becker Categories:

    0 - Asymptomatic, no hemodynamically significant occlusive disease.

    1. - Mild claudication.
    2. - Moderate claudication.
    3. - Severe claudication.
    4. - Ischemic rest pain.
    5. - Minor tissue loss, non-healing ulcer, or focal gangrene with diffuse pedal ischemia.
    6. - Major tissue loss, extending above transmetatarsal level, functional foot no longer salvageable.

    Measured: 30 days

  4. Restenosis by Duplex Ultrasound

    In-Stent Restenosis is re-narrowing within the margins of the stent following the reduction of a previous narrowing. It is defined as the presence of a hemodynamically significant restenosis (≥ 50%), as determined by duplex ultrasonography (DUS) or arteriography. A peak systolic velocity ratio (PSVR) of 2.4 and 2.5 will be used to calculate duplex restenosis.

    Measured: 6 months

  5. Restenosis by Duplex Ultrasound

    In-Stent Restenosis is re-narrowing within the margins of the stent following the reduction of a previous narrowing. It is defined as the presence of a hemodynamically significant restenosis (≥ 50%), as determined by duplex ultrasonography (DUS) or arteriography. A peak systolic velocity ratio (PSVR) of 2.4 and 2.5 will be used to calculate duplex restenosis.

    Measured: 1 Year

  6. Target Lesion Revascularization

    Target Lesion Revascularization (TLR): Any revascularization at the target lesion with or without evidence of target lesion diameter stenosis ≥ 50% determined by DUS or arteriography, with or without new distal ischemic sign (worsening Rutherford Becker Clinical Category that is clearly referable to the target lesion).

    Measured: 6 months

  7. Target Lesion Revascularization

    Target Vessel: The entire vessel in which the treated lesion is located. The boundaries for the iliac artery are the abdominal aortic bifurcation and the superior border of the inguinal ligament.

    Target Lesion Revascularization (TLR): Any revascularization at the target lesion with or without evidence of target lesion diameter stenosis ≥ 50% determined by DUS or arteriography, with or without new distal ischemic sign (worsening Rutherford Becker Clinical Category that is clearly referable to the target lesion.)

    Measured: 1 Year

  8. Stent Fracture

    Stent fractures determined by fluoroscopy .

    Measured: 1 Year

  9. Stent Fracture

    Stent fracture and Involuntary stent migration are types of device System Failure.

    Device System Failure is defined as the inability of the device to provide the intended clinical utility requiring surgical intervention to correct.

    Measured: 1 to 2 years

  10. Stent Fracture

    Stent fracture and Involuntary stent migration are types of device System Failure.

    Device System Failure is defined as the inability of the device to provide the intended clinical utility requiring surgical intervention to correct.

    Measured: 1 to 3 Years

  11. Target Limb Ankle Brachial Index (at Rest)

    Ankle Brachial Index (ABI) is a measure of the fall in blood pressure in the arteries supplying the legs and is used to detect evidence of blockages in the peripheral vessels. It is calculated by dividing the higher systolic blood pressure in the ankle (dorsalis pedis or posterior tibial) of the one leg by the higher of the two systolic blood pressures in the arms. A doppler probe is used to monitor the pulse while a sphygmomanometer is inflated above the artery. The cuff is deflated and the pressure at which the pulse returns is recorded.

    ABI=Highest Ankle Systolic Pressure/Highest Brachial Systolic Pressure

    The ABI is the ratio of the ankle to arm pressure, and an ABI between 0.9 and 1.3 is considered normal. A reduced ABI (less than 0.9) is consistent with peripheral artery occlusive disease, with values below 0.8 indicating moderate disease and below 0.5 severe disease.

    Measured: At baseline

Questions about this trial

What is this clinical trial studying?

A study testing SUPERA Interwoven self-expanding nitinol stent in people with Peripheral Artery Disease and Femoropopliteal Artery Stenosis, run by Abbott Medical Devices at 4 sites in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 0 inclusion and 23 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 19 Sep 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 17 Aug 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Six-minute Walking Distance (time frame: At baseline). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2017.
