AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with narrowed or blocked iliac arteries (pelvic leg arteries) that cause symptoms. It compares the VBX Device with bare metal stents.
- Age
- 18 years and older.
- Sex
- All sexes.
- Disease stage
- Leg pain when walking, pain at rest, or small wounds (Rutherford Category 2-5). New or re-narrowed lesions in the common and/or external iliac artery. Each lesion is >50% narrowed or fully blocked and between 4 and 11 cm (1.6–4.3 in) long. Vessel width about 5 mm to 13 mm. Arteries below must have good flow (<50% narrowed).
- Earlier treatment
- Cannot join after previous stents in the iliac arteries, previous bypass surgery in the treated leg, or a leg artery catheter procedure within 30 days of randomization.
Main reasons for not taking part
- Expected to live less than 1 year, or pregnant.
- Severe kidney weakness (serum creatinine > 2.5mg/dL (221 µmol/L)) without hemodialysis.
- Allergy to stent parts (nitinol, stainless steel, heparin) or cannot take blood-thinning medicines.
- Lesion or aneurysm in the abdominal aorta, or a stent needed within 2 cm (0.8 in) of the inguinal ligament.
- Narrowing only in the common iliac artery treatable with one device, or other leg artery disease needing treatment at the same time.

Who can take part
- Age ≥ 18 years at time of informed consent signature
- Informed Consent Form (ICF) is signed by the subject
- Subject can comply with protocol requirements, including follow-up
- Patient has symptomatic claudication, rest pain, or minor tissue loss (Rutherford Category 2-5)
- Patient has de novo or restenotic lesion(s) found in the common and/or external iliac artery(ies)
- Patient has: Unilateral or bilateral single or multiple lesions (>50% stenosis or chronic total occlusion) each between 4 and 11 cm in length
- Patient has a target vessel diameter visually estimated to be approximately between 5 mm and 13 mm
- Patient has a sufficient (<50% stenotic) common femoral artery and at least one sufficient (<50% stenotic) femoral artery (deep or superficial)
- Patient has at least one sufficient (<50% stenotic) infrapopliteal run-off vessel
Who cannot take part
- Patient has a known intolerance to antithrombotic medications that prevent compliance with study or control device Instructions for Use
- Patient has previous stenting in the iliac arteries
- Patient has previous surgical bypass in the target limb
- Patient is currently participating in another investigative clinical study unless received written approval by the sponsor
- Patient has a lesion requiring drug-coated balloon angioplasty, atherectomy, lithotripsy, or any ablative device to facilitate stent delivery
- Patient has isolated common iliac artery stenosis that can be treated with a single device (i.e., common iliac artery stenosis that does not require kissing stents or extend into the external iliac artery)
- Patient has outflow disease that requires concomitant interventions (i.e. common femoral endarterectomy or femoral / tibial revascularization)
- Patient has a known allergy to stent or stent graft components (including nitinol, stainless steel, or heparin)
- Patient has evidence of a systemic infection
- Patient has severe chronic renal insufficiency (serum creatinine level > 2.5mg/dL) and not undergoing hemodialysis
- Life expectancy <1 year
- Patient is pregnant at time of informed consent
- Patient has had vascular catheterization of the lower extremities within 30 days of randomization (excluding diagnostic angiograms for the study procedure)
- Patient has an abdominal aortic artery lesion or aneurysm
- Patient has a lesion that requires stent placement within 2 cm of the inguinal ligament

About the trial
What the trial wants to find out
The objective of this prospective, multicenter, randomized, controlled clinical trial is to demonstrate the superiority of the VBX Device for primary patency when compared to bare metal stenting in complex iliac occlusive disease.
The 2 groups in the trial
- VBX Device GroupExisting treatment, for comparison
Subject in this group will receive treatment with the GORE VIABAHN® VBX Balloon Expandable Endoprosthesis (VBX)
Treatment: Stenting of the Common and/or External Iliac Arteries with the GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis
- BMS Control GroupExisting treatment, for comparison
Subjects in this group will receive treatment with a commercially available bare metal stent (BMS) that is approved for treatment of the disease
Treatment: Stenting of the Common and/or External Iliac Arteries with Bare Metal Stent
