Summary

This study aims to conduct a randomized, double blind, randomised controlled multicentre trial of sirolimus drug coated balloon versus standard percutaneous transluminal angioplasty for the treatment of superficial and popliteal arterial disease.

Description

The burden of limb loss as a result of peripheral arterial disease (PAD) is high and this problem is set to worsen globally. Treatment of PAD primarily involves revascularisation of the limb. Angioplasty as a first line strategy of revascularization over surgical procedures has been adopted by most vascular centers. Local drug delivery using drug coated balloons (DCB) during angioplasty for PAD can successfully deliver effective local tissue concentrations of anti-proliferative drugs to the lesions in the artery involved in the PAD. This offers the potential for sustained anti-restenotic efficacy.

Randomized trials have shown superiority of Paclitaxel DCBs over just plain-balloon angioplasty for treatment of PAD, and DCB is now considered the standard of care. However a recent meta-analyses which showed increased mortality at two years in patients treated with paclitaxel DCBs have called into question the safety of paclitaxel based DCBs.

Alternative drugs for DCBs are therefore urgently needed and sirolimus offers an attractive alternative. Compared to Paclitaxel, sirolimus is cytostatic in its mode of action with a high margin of safety. It has a high transfer rate to the vessel wall and has been shown to effectively inhibit neointimal hyperplasia in the porcine coronary model. In the coronary artery interventions, preliminary clinical studies using Sirolimus DCBs have also shown excellent procedural and 6 month patency.

Eligibility

Yes No Not Sure

Inclusion Criteria

Age ≥ 21 years or minimum age
Rutherford class 3 to 6 in the target limb
Intraoperative Inclusion Criteria
Single or sequential de novo or re-stenotic lesions (stenosis of > 50% or occlusions) from 2 to 20cm in the femoropopliteal arteries. Lesion is considered as one lesion if there is maximum of 30mm gap between lesions at discretion of investigator. Femoropopliteal arteries are superficial femoral artery, popliteal artery P1 and P2
Inflow free from flow limiting lesions (<50% stenosis) confirmed by duplex or angiography. Subjects with flow limiting inflow lesions (>50% stenosis) can be included if lesion had been treated successfully (<30% residual stenosis) before or during the index procedure
At least one non-occluded crural vessel (ie. without significant stenosis) with angiographically documented run off to the foot

Exclusion Criteria

Comorbid conditions limiting life expectancy ≤ 1 year
Subject is currently participating in another investigational drug or device study that has not reached first primary endpoint yet
Subject is pregnant or planning to become pregnant during the course of the study
Heel gangrene
Prior bypass surgery of target vessel
Planned amputation of the target limb
Failure to successfully cross the target lesion with a guide wire (successful crossing means tip of the guide wire distal to the target lesion in the absence of flow limiting dissections or perforations)
Previously implanted stent in the target lesion
Failure to obtain <30% residual stenosis in a pre-existing lesion
Vulnerable or protected adults
Highly calcific lesions
Bleeding diathesis or another disorder such as gastrointestinal ulceration which restrict the use of clopidogrel or aspirin
Use of DCBs, drug eluting stent, specialty balloons or artherectomy devices during the index procedure. (Non-compliant balloons are not considered specialty balloons)
Known allergy to sirolimus
Intraoperative Exclusion Criteria
Lesions requiring retrograde access (SAFARI)
