Who can join

Age: 18 and older, up to 100. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age of at least 18 years.
• Clinical diagnosis of PAD secondary to atherosclerosis affecting a lower limb.
• ABI <0.90 at rest or with exercise, or a toe-brachial index (TBI) <0.70 if ABI value is >1.30 (non-compressible), or radiographic evidence of PAD that correlates with clinical symptoms.
• Rutherford category 2-4.
• Screening duplex Doppler ultrasound with a SFA or PA lesion with a PSVR >2.4.
• De novo lesion, not previously treated by angioplasty, atherectomy, or stent.
• 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.

You may not qualify if…

• 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).
• Total occlusion of the SFA or PA in the index leg.
• Planned surgical or endovascular procedures to the affected leg on the day of or within 28 days of study drug administration.
• Deep vein thrombosis within the past 3 months.
• Known bleeding disorder.
• Presence of any arterial aneurysm in the index leg.
• Known hypercoagulable state (e.g., protein C deficiency, factor V Leiden mutation, prothrombin G20210A mutation).
• Platelet count <130K, hematocrit <30%, bilirubin or ALT >3.0 times the upper limit of normal.
• Arterial systolic BP >200 mmHg or diastolic BP >100 mmHg at screening or day of procedure.
• 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 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 contrast media, iodine, lidocaine, prilocaine, or EMLA Cream (lidocaine 2.5% and prilocaine 2.5%).
