November 6, 2023 updated by: RenJi Hospital

Comparing the Efficacy of Heparin-boned Viabahn@ Endoprosthesis and Paclitaxel-coated Balloons for Endovascular Treatment of Complex Femoropopliteal Lesions

The purpose of this study is to evaluate the effectiveness of the Viabahn endoprosthesis for treating long femoropopliteal lesions (stenosis ≥ 25cm, occlusion ≥ 15cm) or recurrent in-stent restenosis compared to drug-coated balloons (DCB) with or without a bailout bare nitinol stent.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multicenter, prospective, 1:1 randomized clinical trial with clinical and image follow-up for two years post-procedure. Approximately 60 subjects will be enrolled and randomized into a Viabahn preferred group (study arm) or drug-coated balloons (DCB) group (control arm); Each group will include 30 patients. All enrolled patients will be followed up for 12 months to assess the incidence of restenosis by duplex ultrasound and major adverse events. Follow-up visits occur at 12 and 24 months, as well as telephone visits after 1, 6, 9 and 24 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Primary patency
Time Frame: 24-month
Peak systolic velocity ratio (PSVR ≤2.4) without any repeat intervention.

Freedom from a composite of Major adverse events (MAEs)
Time Frame: 24-month
Freedom from MAEs is defined as freedom from clinically-driven target vessel revascularization (CD-TVR), major amputation, and all-cause of death
24-month

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame: Immediately after interventional surgery
Procedural success is defined as technical or device success without major adverse events during the hospital stay.

Secondary patency
Time Frame: 24-month
Secondary patency is defined as maintaining patency in the target vessel after a repeat intervention to correct complete occlusion in the treated arterial segment.
24-month
Clinically-driven target vessel revascularization (CD-TVR)
Time Frame: 24-month
clinically-driven target vessel revascularization (CD-TVR) is defined as repeat intervention performed during enrollment in the clinical study.

Defined as a sustained upward shift of at least one category on the Rutherford classification without the need for repeated target lesion revascularization (TLR) in surviving patients.
24-month
Secondary sustained clinical improvement
Time Frame: 24-month
Defined as a sustained upward shift of at least one category on the Rutherford classification3, including the need for repeated target lesion revascularization (TLR) in surviving patients.
