Summary

This is a Pivotal, Prospective, randomized, two arm, placebo controlled, single-blind, multicenter trial that will be conducted at approximately 80 sites; approx. 50 sites with at least 50% of subjects will be recruited from USA and approx. 30 sites OUS - Europe, Australia and Asia. Each site will be capped at 30 maximum subjects recruited. The main goal of this clinical trial is to determine the effectiveness and safety of the sirolimus drug coated balloon (DCB) versus standard percutaneous transluminal angioplasty (PTA) for the treatment of below the knee arterial disease. Eligible subjects will be randomised in a 1:1 allocation ratio and stratified by recruiting countries. Each subject will be randomized to receive either: 1. MagicTouch PTA sirolimus coated balloon catheter (DCB) in addition to standard balloon angioplasty or 2. Placebo balloon angioplasty in addition to standard balloon angioplasty (PTA).

Detailed description

The burden of limb loss because 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 many vascular centres. In recent years, studies have shown that local drug delivery using drug coated balloons (DCB) during angioplasty for PAD can successfully deliver effective local tissue concentrations of antiproliferative 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 femoropopliteal occlusive disease, and DCB is now considered the standard of care in many regions. However, the efficacy of Paclitaxel below the knee is less clear, as multiple randomized trials evaluating Paclitaxel-coated DCBs below the knee have failed to meet their primary endpoints. Alternative drugs for DCBs are therefore needed and sirolimus may offer 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- \& 12- months patency. This study aims to conduct a single blind, randomised controlled multicentre trial of sirolimus drug coated balloon versus standard percutaneous transluminal angioplasty in patients with below the knee arterial disease.

Conditions

• Arterial Disease of Legs
• Below-the-knee Obstruction
• PAD - Peripheral Arterial Disease

Interventions

Type	Name	Description
DEVICE	MagicTouch PTA Sirolimus drug coated balloon	All patients must first be treated with pre dilatation with a standard balloon angioplasty using any standard balloon catheters at the discretion of the operator. Magic Touch PTA Sirolimus coated balloon catheter is an adjunct treatment that should be used in combination with standard balloon angioplasty. Following successful crossing of wire across the lesion and plain balloon angioplasty of arterial lesion with successful lesion preparation with residual lesion \<30%, subjects will be randomized to receive study device balloon. If patients are assigned to MagicTouch PTA Sirolimus DCB, the Angioplasty of lower limb will be performed with this device in addition to standard balloon angioplasty.
DEVICE	Placebo balloon angioplasty	For participants randomized to a Placebo balloon angioplasty group, a Placebo balloon angioplasty in addition to standard balloon angioplasty will be performed.
