An RCT Evaluating the Safety and Efficacy of the Endovascular Treatment of Subjects with Stenotic or Restenotic Lesions of the Common Femoral Artery with the Supera Vascular Mimetic Implant Compared to Surgical Common Femoral Artery Endarterectomy
The SUPERSURG RCT trial investigates the efficacy and safety of the endovascular treatment of stenosis or restenosis in the common femoral artery (CFA) of patients presenting with Rutherford classification 2,3 or 4 with a Supera Vascular Mimetic Implant of Abbott, compared to classic surgical common femoral artery endarterectomy. The Supera Vascular Mimetic Implant has an interwoven design and has a high crush resistance and is, when correctly implanted, an ideal stent to treat eccentric calcified plaques in the CFA. An expected total of 143 patients will be treated with the Vascular Mimetic Implant of Abbott and compared to a control group of another 143 patients that will be treated with classic surgical endarterectomy of the common femoral artery. Assignment to the treatment groups will be at random. Patients will be invited for a follow-up visit at 1, 6, 12, 24 and 36 months post-procedure. The primary efficacy endpoint is defined as follows: freedom from clinically-driven target lesion revascularization and binary restenosis at 12 months. The primary safety endpoint is defined as follows: a composite of overall death, cardiac, pulmonary, renal complications, sepsis, target lesion revascularisation and wound related complications through 30 days post-index procedure. The secondary endpoints are defined as technical success, primary patency in the deep femoral artery, primary patency in the target lesion, target lesion revascularisation, target vessel revascularisation, binary restenosis, duration of initial hospital stay, sustained clinical improvement, change of walking impairment questionnaire score from baseline, change in target limb Rutherford classification, change in target limb ABI/TBI from baseline, all cause death, thrombosis at the target lesion through 6, 12, 24 and 36 months post-procedure.
• 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.
