Официальное название

MAGICAL BTK: Randomized Controlled Trial of MAGIcTouch - Sirolimus Coated BALloon Versus Standard Balloon Angioplasty in The Treatment of Below The Knee Arterial Disease

Обзор

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).

Подробное описание

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.

Вмешательства

• Устройство 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 randomiz
• Устройство 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.

Intraoperative Inclusion Criteria:

• Single or sequential de novo or re-stenotic lesions (stenosis of > 50% or occlusions) from 2 to 20cm in the proximal 200mm of below the knee arteries. Lesion is considered as one lesion if there is maximum of 30 mm gap between lesions at discretion of investigator. Below the knee arteries are Tibio-peroneal trunk, Peroneal bifurcation, anterior tibial artery, posterior tibial artery and peroneal artery. With documented Distal Run off a maximum of two tibial vessels can be treated in the index procedure. 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.
• Target vessel has angiographically documented unimpaired (<50% stenosis) run off into a named Tibio-pedal artery (Peroneal, Anterior Tibial/ Dorsalis Pedis/ Posterior Tibial Artery)
