Official title
Prospective, Non-randomized, European Feasibility Clinical Study to Assess the Safety and Performance of the Xeltis Peripheral Artery Disease (XPAD) Bypass Conduit.
Overview
A prospective, single arm, non-randomized European feasibility study to evaluate the safety and performance of the XPAD conduit in patients with peripheral arterial occlusive disease (PAOD), scheduled to undergo elective lower-limb, above or below the knee, bypass surgery.
Interventions
- Device XPAD conduit
The XPAD bypass conduit is a sterile, restorative biodegradable polymer-based vascular conduit, consisting of a tubular structure with a 33cm length and 6mm inner diameter. It is comprised of a highly porous polymer matrix and an embedded electropolished nitinol reinforcement layer (Strain Relief System). The XPAD conduit is in a straight configuration and may be implanted in the lower limb for elective bypass surgery.
Primary outcome measures
- Primary patency rate [Time frame: 12 months post-implant]
- Freedom from device-related SAE [Time frame: Day 1, 30 days, 6 months, and 12 months post-implant]
Secondary outcome measures (7)
- Implantation success rate [Time frame: Day 1]
- Freedom from Major Bleeding events [Time frame: Day 1, 30 days and 6 months post-implant]
- Patency (primary, primary assisted, and secondary) rates [Time frame: 6, 12, 24, 36, 48 and 60 months post-implant]
- Freedom from device-related SAE [Time frame: 24, 36, 48 and 60 months post-implant]
- Rate of wound/conduit infections [Time frame: 30 days, 6, 12, 24, 36, 48 and 60 months post-implant]
- Freedom from Major Amputations [Time frame: 30 days, 6, 12, 24, 36, 48, and 60 months post-implant]
- Freedom from all-cause mortality [Time frame: 30 days, 6, 12, 24, 36, 48, and 60 months post-implant]
Eligibility criteria
Inclusion criteria
- Participants with peripheral artery occlusion who require elective lower-limb bypass surgery
- Participant has Rutherford grade 3 or 4 occlusive vascular disease and TASC C or D lesions.
- At least 18 years of age at screening
- Suitable anatomy while avoiding joints (assessed by a pre-procedural contrasted CT scan or previous angiogram assessed up to 90 days prior to baseline)
- Participant has been informed of the nature of the study, agrees to its provisions, and has provided written informed consent
- Participant has been informed and agrees to pre- and post-procedure follow-up, including follow-up angiography
- Life expectancy of at least 24 months
Exclusion criteria
- Participant requires, or is scheduled for, a cardiac surgical procedure or a different vascular surgical procedure within 30 days of study procedure.
- Stroke or myocardial infarction event within 6 weeks of the procedure or evidence of prior massive stroke (Modified Rankin Scale 3 or above)
- History of acute arterial occlusion requiring an emergent intervention within the last 12 months
- Severe chronic renal insufficiency (serum creatinine >2.5 mg/dL) or undergoing hemodialysis
- Previous renal transplant
- Uncontrolled arterial hypertension (BP >200 mmHg) at 2 successive readings
- Uncontrolled or poorly controlled diabetes
- Abnormal blood values that could influence participant recovery and or/ graft hemostasis
- Reduced liver function, defined as: >2x the upper limit of normal for serum bilirubin, International Normalized Ratio (INR) >1.5 or prothrombin time (PT) >18 seconds
- Any active local or systemic infection
- Known heparin- induced thrombocytopenia, active bleeding disorder and/or any coagulopathy or thromboembolic disease
- Allergies to study device (nitinol) or agents/medication, such as contrast agents, aspirin or NOACs, that can't be controlled medically
- Previous enrolment in this study
- Participant is participating in another study
- Pregnant or breastfeeding woman or woman in fertile period not taking adequate contraceptives
- Any other condition which, in the judgement of the investigator would preclude adequate evaluation for the safety and performance of the study conduit
Intra-operative exclusion criteria:
1\. Unsuitable anatomy to implant the XPAD conduit (e.g. target vessel diameter smaller than anticipated; severe calcification)
