Active clinical trials for "Peripheral Vascular Diseases"

The purpose of this study is to evaluate the safety and effectiveness of the Jetstream Atherectomy System for the treatment of Japanese patients with symptomatic occlusive atherosclerotic lesions in native superficial femoral artery (SFA) and/or proximal popliteal arteries (PPA).

The aim of the study is to assess the safety and efficacy of the use of the Eximo's B-Laser™ catheter in subjects affected with Peripheral Artery Disease (PAD) in lower extremity arteries.

Patients with peripheral arterial disease often have walking impairment due to insufficient oxygen supply to lower extremity skeletal muscle. In an aging rat model, we have previously shown that daily calf muscle stretching improves endothelium-dependent dilation of soleus muscle arterioles and blood flow during exercise. The effect of muscle stretching on endothelial function and walking distance in patients with peripheral arterial disease is unknown. We performed a prospective, randomized, non-blinded, crossover study in 13 patients with stable symptomatic peripheral artery disease. Patients were randomized to undergo either 4 weeks of passive calf muscle stretching (ankle dorsiflexion splints applied 30 minutes/day, 5 days/week) followed by 4 weeks of no muscle stretching (control group) and vice versa. Endothelium-dependent flow-mediated dilation and endothelium- independent nitroglycerin-induced dilation of the popliteal artery and a 6 minute walk test were evaluated at baseline and after each 4 week treatment interval. Patients crossed over to the other treatment arm after 4 weeks and endothelium-dependent flow-mediated dilation and endothelium- independent nitroglycerin-induced dilation of the popliteal artery and the 6 minute walk test were repeated.

The MODIFY Pilot clinical study in Europe looks to evaluate acute and procedural outcomes using a new calcium atherectomy and modification solution in patients with balloon resistant calcified lesions in infrainguinal disease. The intent is to both debulk and modify the vessel to restore blood flow, improve vessel compliance and drive better outcomes. The MODIFY Pilot study will evaluate safety and performance measurements.

A prospective, multicenter, randomized study evaluating the use of Jetstream Atherectomy (JS) followed by DCB in comparison to the use of plain old balloon angioplasty (POBA) followed by DCB alone in the treatment of complex lesions in femoropopliteal arteries in subjects with claudication (Rutherford Clinical Category (RCC) of 2-4) (complex lesions are defined as long (≥ 10 cm) lesions, or moderately or highly calcified lesions, or chronic total occlusions irrespective of length).

The main objective is to evaluate the effect of Propionyl-L-Carnitine Hydrochloride on clinical pharmacokinetic characteristics and its effect of clinical pharmacokinetic characteristics and safety on healthy Chinese subjects to provide a basis for market authorization registration

The primary objective for this study is to prove the safety and effectiveness of the Spectranetics Turbo-Elite catheter in atherectomy treatment for infrainguinal arteries with catheter to vessel sizing of at least 50%.

The objective of this clinical investigation is to evaluate the short- and long-term (up to 24 months) outcome of treatment by means of dilation with the Passeo-18 Lux drug releasing balloon and by Pulsar-18 stent implantation in symptomatic (Rutherford 2-4) femoro-popliteal arterial stenotic or occlusive lesions.

Remote ischemic Preconditioning (RIPC) is a phenomena first observed in cardio-thoracic patients in which exposing the limbs for periods of short intermittent ischemia produces protective effect on heart muscle. The concept was applied to many other parts of the body and the results are positive so far. No human trials on this concept has been conducted in patients with peripheral vascular disease so far but applying the concept for healthy individuals shows vessels dilatation and animal trials shows degree of new vessels formation in addition to reports of symptoms improvement. The trial candidates will be allocated blindly in 4 groups. All groups will have advice about exercise which is the standard practice now. The first group will have supervised exercise. The second group will in addition to the supervised exercise get the ischemic preconditioning with the blood pressure cuff. The third group will get the ischemic preconditioning and the fourth group will get the standard exercise advice. All candidates will have Magnetic Resonance Image Scan (MRA) for their blood vessels in the beginning of the trial and again at the end. The effect of the RIPC (Remote ischemic Preconditioning) and exercises on patient symptoms, new vessel formation and other parameters will be recorded

Shockwave Medical Inc. intends to conduct a prospective, multi-center, single blind, randomized (1:1) study of Lithoplasty treatment used in combination with DCB versus standard balloon angioplasty used in combination with DCB to treat moderate and severely calcified femoropopliteal arteries. Assuming that roughly 15% of the subjects will be lost-to-follow-up, a total of up to 400 subjects (200 per treatment arm) will be enrolled in the study at up to 60 sites in Europe, the United States and New Zealand. In addition to the randomized study, an observational study of subjects who do not meet the inclusion/exclusion criteria for the randomized study will be conducted. The objective of the observational study is to assess the real-world acute performance of the Shockwave Medical Peripheral Lithoplasty System in the treatment of calcified, stenotic, peripheral arteries. The observational study is a prospective, multi-center, single arm observational study for subjects who do not meet the inclusion/exclusion criteria of the randomized study. A maximum of 1000 subjects at the same 60 sites will be enrolled in the observational study. Once enrollment in the randomized portion of the study is complete, subjects may continue to be enrolled in the observational study provided they meet OS eligibility criteria.
