简要总结
This study aims to demonstrate the safety and efficacy of the SELUTION SLR™ 018 DEB compared to plain (uncoated) balloon angioplasty in the treatment of peripheral arterial disease (PAD) in the superficial femoral artery (SFA) and proximal popliteal artery (PPA).
详细描述
Prospective, multi-center, single blinded, 2:1 randomized, controlled, superiority clinical trial.
This study will enroll up to 300 randomized subjects, and up to 20 subjects in a parallel pharmacokinetic (pK) sub study, at up to 60 clinical sites in the United Stated (US), Europe (EU) and Asia. A minimum of 50% of randomized subjects will be enrolled in the US. No more than 45 subjects (15% of the total randomized cohort) can be enrolled in the randomized cohort at any single investigational site.
Randomized Cohort:
Up to 300 subjects who meet all eligibility criteria will be randomized 2:1 by permuted block method (stratified by site and adjunctive lesion preparation) to one of two treatment arms:
- Intervention - treatment with SELUTION SLR™ 018 DEB
- Control - treatment with commercially available PTA (uncoated balloon)

- •Angiographic Inclusion Criteria:
- •Angiographic evidence that target lesion lies within the superficial femoral artery and/or proximal popliteal artery (P1 and P2 only).
- •Angiographic evidence that the target lesion consists of either a de novo lesion or a non-stented restenotic lesion, or a combination of both, that meets one of the following criteria:
- •A. A stenosis of 70-99% with lesion length between ≥3cm and <20cm by visual estimation.
- •B. A total (100%) occlusion with lesion length between ≥3cm and ≤10cm by visual estimation.
- •C. A combination lesion (stenosis and total occlusion) must have a total lesion length between ≥3cm and <20cm by visual estimation with an occluded segment that is ≤10cm by visual estimation.
- •D. If multiple lesions are to be treated, then only 2 lesions may be included. The total combination of lengths must be between ≥3cm and < 20cm by visual estimation, and there must be at least 5 cm of artery that is not to be treated between them.
