Active clinical trials for "Peripheral Arterial Disease"

This study proposes to evaluate the potential of leg thermotherapy as a non-pharmacological intervention that could improve the mobility and exercise tolerance of patients with intermittent claudication. Thermotherapy is a simple, easily applicable therapy that enhances exercise tolerance in patients with chronic heart failure by improving peripheral vascular endothelial function.

The GoldenFlow (Lifetech Scientific, Shenzhen, China) is a novel woven-nitinol stent designed to have superior radial strength, flexibility and durability compared to standard nitinol stents for femoropopliteal lesions. This is a first-in-man study to evaluate the safety and efficacy of GoldenFlow woven-nitinol stent for intraluminal treatment of peripheral vascular disease in the femoropopliteal arteries.

The aim of this clinical trial is to evaluate the safety and efficacy of the novel Luminor® paclitaxel drug-eluting balloon (iVascular, S.L.U., Barcelona, Spain) in inhibiting restenosis and in ensuring long-term patency.

Some studies have reported improved vascular function with the supplementation of L-arginine in participants with cardiovascular disease (CVD). Several clinical studies have also begun the investigation of L-arginine supplementation in participants with peripheral artery disease (PAD). This is particularly important as currently there are limited options available to medically manage intermittent leg pain resulted from PAD. Although some of these short-term clinical trials suggested that oral L-arginine improved walking distance or improved walking speed in participants with PAD, these results were not consistent. Further, only 1% of the oral supplemented L-arginine is available for the NO production as the rest is metabolised by the body. A better way to provide the body with substrate to produce NO is therefore needed. The natural amino acid and food component, L-citrulline has been suggested to be a good candidate for this purpose. L-citrulline, named after watermelon citrullus vulgaris from which it was first isolated, is a natural precursor of L-arginine. Studies have shown that L-citrulline is metabolised by the body to a lesser degree compared to L-arginine and hence is an effective precursor of arginine in peripheral tissues, including endothelial cells. Oral L-citrulline supplementation also eliminates some of the unwanted effects associated with oral arginine supplementation and it is well tolerated without known side effects. In addition, L-citrulline is a supplement that is available over-the-counter. Thus, oral supplementation of L-citrulline may be a new intervention strategy in participants with PAD. The investigators hypothesize that the oral food supplement L-citrulline, unlike L-arginine, reverses endothelial dysfunction. In a multinational, multicenter, double blinded, randomised, placebo-controlled cross-over trial the effects of L-citrulline in peripheral artery disease will be investigated.

The aim of the prospective, multicentre, single-arm study is to assess safety and efficacy of a drug eluting stent in Nitinol alloy (NiTiDES) in term of vessel patency and composite event-free survival rate up to two years follow-up in focal/medium length lesions in patients with ischemic obstruction of superficial femoral arteries or/and proximal popliteal arteries.

PREVEIL is a prospective, multi-center, single-arm clinical trial to assess the safety and functionality of the SurModics drug coated balloon (DCB) in the treatment of subjects with symptomatic peripheral artery disease (PAD) due to de novo stenoses of the femoral and popliteal arteries. The trial will enroll up to 15 subjects.

This is an Outside the United States, post-CE Mark, multi-center, single-arm, non-blinded study designed to investigate the safety and efficacy of the Tack Endovascular System. This study will evaluate subjects with PAD who receive PTA (with a drug-coated balloon (DCB)) in the SFA and in popliteal arteries, ranging in diameter from 2.5mm to 6.0mm and lesion lengths of ≥20mm and ≤150mm, and have a resulting dissection(s) type(s) A through F. TOBA III will also evaluate the safety and efficacy of the device when used to treat a sub-group presenting with longer lesions of >150mm and ≤250mm.

This study evaluates the performance of the CorPath 200 System to deliver guide wires and balloons to blockages in the arteries of the leg.

To demonstrate that the BioMimics 3D Stent System meets the performance goals defined by VIVA Physicians, Inc. for the safety and effectiveness of Nitinol stents used in the treatment of symptomatic disease of the femoropopliteal artery. It is a prospective, single-arm, multicenter clinical trial.

The objective of this clinical investigation is to evaluate the short-term (up to 12 months) outcome of treatment by means of the self-expanding iVolution nitinol stent in symptomatic (Rutherford 2-4) femoropopliteal arterial stenotic or occlusive lesions.
