Clinical Trial 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.

Recruitment information / eligibility

• Gender: All
• Age group: 21 Years and older

Eligibility

Inclusion Criteria:

1. Age = 21 years or minimum age

2. Rutherford class 3 to 6 in the target limb

Intraoperative Inclusion Criteria

3. 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

4. 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.

5. At least one non-occluded crural vessel (ie. without significant stenosis) with angiographically documented run off to the foot.

Exclusion Criteria:

1. Comorbid conditions limiting life expectancy = 1 year

2. Subject is currently participating in another investigational drug or device study that has not reached first primary endpoint yet

3. Subject is pregnant or planning to become pregnant during the course of the study

4. Heel gangrene

5. Prior bypass surgery of target vessel

6. Planned amputation of the target limb

7. Previously implanted stent in the target lesion

8. Vulnerable or protected adults

9. Bleeding diathesis or another disorder such as gastrointestinal ulceration which restrict the use of clopidogrel or aspirin

10. Known allergy to sirolimus

Intraoperative Exclusion Criteria

11. 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)

12. Failure to obtain <30% residual stenosis in a pre-existing lesion

13. Highly calcific lesions

14. Use of DCBs, drug eluting stent, specialty balloons or artherectomy devices during the index procedure. (Non-compliant balloons are not considered specialty balloons)

15. Lesions requiring retrograde access (SAFARI)

Related Conditions & MeSH terms

• Arterial Disease
• Atherosclerosis
• Peripheral Arterial Disease
• Peripheral Artery Disease

Intervention

Device:
• MagicTouch PTA sirolimus drug coated balloon (DCB)
For participants randomised to MagicTouch PTA sirolimus DCB, following successful plain balloon angioplasty of the arterial lesion, (defined as <30% residual stenosis after treatment at rated burst pressure of the angioplasty balloon), MagicTouch PTA sirolimus coated balloon will be applied at the lesion after appropriate sizing using the diameter of the plain balloon angioplasty.
• POBA standard balloon
For participants randomised to the standard balloon angioplasty group, a placebo standard balloon which is identical to the SCB will also be applied at the lesion after appropriate sizing using the diameter of the plain balloon angioplasty.
