Basic information
Public title A clinical investigation of SM-01 stenting versus balloon angioplasty for the treatment of superficial femoral artery disease.
Acronym SM-01
Scientific Title A clinical investigation of SM-01 stenting versus balloon angioplasty for the treatment of superficial femoral artery disease.
Scientific Title:Acronym SM-01

Condition Patient with intermittent claudication who shows no sign of improvement with exercise or drug treatment. The SFA lesion(s) should be de novo or restenotic (one long or multiple, serial native lesions with total length >= 40 mm and <= 150 mm).
Classification by specialty
Cardiology Vascular surgery Radiology
Classification by malignancy Others
Genomic information NO

Narrative objectives1 The main objective is to evaluate the safety and efficacy of SM-01 stenting for the treatment of SFA lesions as compared to PTA.If SM-01 is used in a PTA-bailout patient, the case will be assessed separately.

Key inclusion criteria 1. Age >= 20 years.
2. Symptomatic leg ischemia by Rutherford Classification (category1, 2, or 3).
3. Lesion length >= 40 mm to <= 150 mm. (must be treatable with no more than two SM-01 stents. Overlap should be about 1cm if two stents are used)
4. Reference vessel diameter (RVD) >= 4.0 mm and <= 7.0 mm.
5. All lesions are to be located >= 3.0 cm proximal to the superior edge of the patella, and >= 1.0 cm distal to the SFA / PFA bifurcation.
6. >= 50% stenosis or total occlusion.
7. Patent infrapopliteal and popliteal arteries, i.e., single-vessel runoff or better with at least one of three vessels patent (< 50% stenosis) to the ankle or foot.
8. Patient or legally authorized representative must provide written informed consent prior to initiation of study procedures.
9. A patient with bilateral obstructive SFA disease is eligible for enrollment into the study. If a patient with bilateral disease is enrolled, the target limb will be the more severe limb. The more severe limb will be selected according to clinical symptomatology. If clinical symptomatology is similar, the more clinically severe lesion will be selected. The contralateral procedure should not be done until at least 30 days after the index procedure of the more severe limb was attempted.
Key exclusion criteria 1. Recent hemorrhagic disease within the past 3 months.
2. Aneurysm in the SFA or popliteal artery.
3. Acute limb occlusion.
4. Procedures which are pre-determined to require stent-in-stent placement to obtain patency, such as severe calcification which is resistant to stenting, or for in-stent restenosis.
5. Poor iliac or common femoral "inflow".(However, intervention to restore adequate blood flow prior to the treatment of the study lesion is allowed.)
6. Known allergies to aspirin, heparin, or ticlopidine, or bleeding diathesis.
7. Patients unable or unwilling to tolerate anticoagulant or antiplatelet therapy.
8. Patients unable or unwilling to tolerate contrast agents used in intravascular procedures.
9. Allergic to nitinol or tantalum.
10. Women who are pregnant or lactating, or of child bearing potential, or with a desire to be a parent during the study period.
11. Significant vessel tortuosity or other parameters prohibiting access to the lesion or which would prevent delivery of the stent device.
12. Revascularization involving the same limb 30 days prior to the index procedure or a planned re-vascularization within 30 days after the index procedure.
13. Previously implanted stent(s) at the same site in the artery to be treated.
14. Requiring stent placement in the distal SFA or popliteal artery.
15. Presence of a femoral artificial graft.
16. History of participating in any other clinical study within 1 year.
17. Life expectancy less than 3 years, or any other factors preventing clinical follow-up.
18. Receiving dialysis or immunosuppressant therapy
19. Serum creatinine level >= 2.0 mg/dL before procedure.
20. A principal investigator or a co-principal investigator determines that patient is unsuitable for this study.
