Beschreibung
Screening: Initial study inclusion criteria
- Age of at least 18 years.
- Clinical diagnosis of PAD secondary to atherosclerosis affecting a lower limb.
- Rutherford category 3-5.
- De novo lesion, not previously treated by angioplasty, atherectomy or stenting.
- Scheduled to undergo angioplasty of the distal popliteal, tibial or peroneal arteries.
- If female and of childbearing potential (premenopausal and not surgically sterile) must have a negative pregnancy test at the screening visit and be willing to use contraception from the time of the screening visit to 1 week following study drug administration. Acceptable methods of birth control include abstinence, barrier methods with spermicide, implants, injectables, oral contraceptives, intra-uterine device, or a vasectomized partner.
- Ability to understand and comply with the requirements of the entire study and communicate with the study team.
Ability to provide written informed consent using a document that has been approved by the required institutional review board.
Procedure: Study inclusion criteria to be determined at the time of the angioplasty procedure
- Atherosclerotic lesion with >50% stenosis in the popliteal (distal to the center of the knee joint space, the P3 segment), tibial or peroneal artery prior to angioplasty.
- Successful revascularization without the use of stenting of the target lesion; no flow limiting dissection and <30% residual lumen stenosis as compared with an adjacent non-diseased lumen diameter.
Exclusion Criteria Screening: Initial study exclusion criteria
- Patients in whom arterial insufficiency in the lower extremity is the result of an immunologic or inflammatory non-atherosclerotic disorder (e.g., Buerger's disease, vasculitis).
- Planned above ankle amputation on ipsilateral limb within 4 weeks of study drug administration.
- Prior or planned stenting of the target lesion.
- Deep vein thrombosis within the past 3 months.
- Known bleeding disorder.
- Known hypercoagulable state (e.g., protein C deficiency, factor V Leiden, prothrombin G20210A mutation).
- Platelet count <130K, hematocrit <30%, bilirubin or ALT >3.0 times the upper limit of normal.
- Renal failure with existing dependence on dialysis or an eGFR by MDRD calculation of < 20 mL/min/1.73 m2.
- Pregnancy, lactation or plans to become pregnant during the course of the study.
- Presence of any significant medical condition that might significantly confound the collection of safety and efficacy data in this study.
- Malignancy or treatment for malignancy within the previous 12 months with the exception of localized basal cell or squamous cell skin cancer, or any cancer in situ.
- Treatment with any investigational drug within the previous 30 days or investigational antibody therapy within 90 days prior to signing informed consent.
Known allergy to radiocontrast agents.
Procedure:
Exclusion criteria to be determined at the time of the angioplasty procedure
- Reference vessel diameter < 2 mm and > 8 mm.
- Severe concentric medial calcification of the target lesion thought to interfere with study drug delivery to the adventitia based on fluoroscopic appearance.
- Aneurysm in the target vessel.
- Failure to cross the target lesion with a guide wire; however subintimal wire crossing is allowed.
- Stenting of the target lesion.
