NCT ID NCT04349657

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares a new stent (Supera) to standard surgery for treating blockages in the leg's main artery. About 286 people with moderate to severe leg pain or sores will be randomly assigned to get either the stent or surgery. Researchers will check if the stent keeps the artery open as well as surgery and if it causes fewer complications.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Supera Peripheral Stent System
What this could lead to
If successful, this could offer a less invasive alternative to surgery for treating blocked leg arteries, potentially reducing recovery time and complications.
What could go wrong
This is a mid-stage trial with 286 participants. The stent may not work as well as surgery, or could cause complications like re-blockage or bleeding. Results may not apply to all patients.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 286 people

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Sep 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patient is ≥18 years old * Patient presenting a score from 2 to 4 following Rutherford classification * Patient is willing to comply with specified follow-up evaluations at the specified times * Patient understands the nature of the procedure and provides written informed consent, prior to enrolment in the study * Patient has a life expectancy of at least 12 months * Prior to enrolment, the guidewire has crossed the target lesion in the endovascular arm. In the surgical arm, the endarterectomy needs to be performed with primary suture or patch implantation * De novo stenotic or restenotic (post-PTA) lesions (\<100%) located in the common femoral artery, suitable for both endovascular therapy and endarterectomy * Target lesion is located within the native CFA: localized between 1cm proximal to the origin of the circumflex iliac artery and the proximal (2cm) superficial femoral artery and deep femoral artery (2cm) (Azéma type 2 and 3 lesions) * There is angiographic evidence of a patent deep femoral artery and/or superficial femoral artery * The target lesion has angiographic evidence of \>50% stenosis. Occlusions are not allowed. Exclusion Criteria: * Presence of another stent in the target vessel that was placed during a previous procedure * Previous open surgery in the ipsilateral groin * Patients contraindicated for antiplatelet therapy, anticoagulants or thrombolytics * Patients who exhibit persistent acute intraluminal thrombus at the target lesion site * Patients with known hypersensitivity to nickel-titanium and heparin, including those patients who have had a previous incidence of heparin-induced thrombocytopenia (HIT) type II * Known allergy to contrast media that cannot be adequately pre-medicated prior to study procedure * Patients with uncorrected bleeding disorders * Female patients with child bearing potential not taking adequate contraceptives or currently breastfeeding * Ipsilateral inflow (aorto-iliac) artery treatment before target lesion treatment with a residual stenosis \>30% * Use of thrombectomy, atherectomy or laser device during procedure * Any patient considered to be hemodynamically unstable at onset of procedure * Severe medical comorbidities (untreated coronary artery disease/congestive heart failure, severe chronic obstructive pulmonary disease, metastatic malignancy, dementia, etc.) or other medical condition that would prelude compliance with the study protocol or 1-year life expectancy * Major distal amputation (above the ankle) in the study limb or non-study limb * Target lesion involves an (pseudo-)aneurysm or is adjacent to an (pseudo-)aneurysm (within 5mm) * Iliac inflow disease requiring treatment, unless the iliac artery disease is successfully treated first during the index procedure. Success is defined as ≤30% residual diameter stenosis without death or major complications * Presence of an aortic, iliac or femoral artificial graft * Occlusion in the target lesion * Presence of an interposition graft with/without profunda reimplantation
