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.

Detailed 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.

Interventions

Type	Name	Description
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.
DEVICE	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.
