STAR-PAK Study: Evaluating the Safety and Efficacy of PAK® (Paclitaxel Coated Balloon) in Treating Atherosclerotic Femoro-Popliteal Lesions
The primary objective of the study is to evaluate the performance and the safety of the PAK® DCB Catheter in the treatment of de novo and restenotic atherosclerotic lesions in the superficial femoral and/or popliteal arteries (SFA/PA) of patients with symptomatic peripheral artery disease (PAD). The study enrolls patients who have been diagnosed with peripheral artery disease with stenosis of the superficial femoral or popliteal artery and are qualified for endovascular revascularization. Lower extremity peripheral artery disease may be asymptomatic or may be accompanied by clinical symptoms due to restricted blood flow to the lower extremities. The management of a patient diagnosed with peripheral arteriosclerosis is primarily aimed at reducing symptoms of limb ischemia and improving blood supply to the limb, as well as seeking to halt the progression of the disease. Treatment of lower extremity atherosclerosis with percutaneous methods is a well-known minimally invasive and recommended treatment for lower extremity ischemia. A maximum of 120 patients will be included in the study. All patients included in the study will receive treatment with the investigational device. The study will use the PAK balloon catheter, which is CE certified and approved for the treatment of patients with peripheral vascular disease. That is, it is also used as standard outside the study. The test procedure with the study device is in accordance with its registration and instructions for use.
• Age ≥ 18 years.
• Written informed consent of the patient to participate in the study.
• Symptoms of lower limb ischemia defined by Rutherford classification from 2 to 4.
• At least one de novo or restenotic lesion, in SFA and/or PA defined as a lesion with a proximal origin \>10mm from SFA origin and a distal end above the knee joint (at least 3 cm above bottom of the femur- P1).
• Target Lesion \>60% stenosis in the SFA or PA (based on angio-CT and/or confirmed in angiography).
• Target Lesion \<150 mm that consists of no more than two adjacent lesions ≤ 25mm apart and is able to be completely covered with inflation of single investigated PAK DCB (with minimum of \>5mm proximal and distal margin.
• Note: Adjacent or tandem lesions must be treated as a single lesion.
• Reference Vessel Diameter (RVD) between 4.0 and 8.0mm and within treatment range of PAK® DCB to be used 1:1 at the target lesion.
• Angiographic evidence of distal run-off demonstrated by at least one patent tibial vessel without evidence of significant ≥50% angiographic stenosis from origin to ankle.
• In-flow vessel (both iliac and femoral) without significant ≥50% angiographic stenosis or successful treatment (≤30% residual stenosis with no complications) of a diseased in-flow vessel at least 30 days prior to the index procedure.
⁃ Note: treatment of contralateral iliac arteries is allowed.
