Active clinical trials for "Peripheral Vascular Diseases"

To utilize near-infrared spectroscopy to investigate if the research device, which induces muscle stretching, and creatine loading impact submaximal exercise performance in aged and PAD patients. Near-infrared spectroscopy (NIRS)-derived tissue oxygenation responses will be obtained during device placement (muscle stretch) and during a walking test (i.e., six-minute walk test). Muscle oxygenation at rest and during device placement will be assessed with Magnetic Resonance Imaging. It is hypothesized that the stretching protocol will improve both NIRS-derived tissue oxygenation and magnetic resonance-derived muscle oxygenation and that creatine supplementation will further improve phosphorus metabolite muscle performance. All patients will undergo either 4 weeks of stretch training with- or- without creatine supplementation according to previously defined creatine guidelines.

The individual restrictions of daily life for patients with PAD are more important than statistical facts for mortality and morbidity. Intermittent claudication causes a progressive reduction of the pain-free walking distance (PWD) as an expression of a worsening PAD. This decrease in physical capability results in a decline of mental health and relevantly reduces the patients' quality of life (QoL). Supervised exercise therapy (SET) is a cornerstone in the conservative management of intermittent claudication and extends the PWD. Even though SET is easy to practice and highly cost effective, the adherence to perform SET on a regular base is rather low. The underuse of exercise can be partly explained by the lack of institutional resources, but also by both patients' and physicians' lack of interest in exercise. Mobile health (mHealth) technologies increase the incentives and provide digital support for patients with PAD on several treatment levels. They might lead to a higher adherence to exercise training and offer new scopes in patient-centered healthcare, but so far studies show opposite results. Because app stores are flooded with health and fitness apps, specific support tools are highly desired by patients with PAD and PAD-specific solutions are missing so far. Based on this background, the investigators developed a smartphone app named TrackPAD to provide PAD-specific support for SET. The TrackPAD pilot study was designed as a 2-armed randomized controlled trial and included patients with diagnosed and symptomatic PAD. Patients were randomized by the Center for Clinical Studies in Essen using the TENALEA software into 2 groups. The control group included participants with standard care and no further mobile intervention. The intervention group included participants with standard care and additional mHealth-based self-tracking of their physical activity using trackPAD.

The purpose of this study is to assess safety and the inhibition of restenosis of the CVI Paclitaxel-coated PTA Balloon Catheter in the treatment of de-novo occluded/stenotic or reoccluded/restenotic superficial femoral (SFA) or popliteal arteries. The primary endpoint for this analysis is late lumen loss at six (6) months.

A non-randomized, prospective, global clinical trial of the Avinger Pantheris System, an atherectomy device that provides directional visualization and imaging as an adjunct to fluoroscopy to aid removal of plaque in diseased lower extremity arteries.

An evaluation of the safety and performance of the STANZA Drug-eluting Resorbable Scaffold (DRS) system for the treatment of patients with obstructive superficial femoral artery disease.

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.

The main purpose of this study is to evaluate the safety and feasibility of regenerative therapy with expanded adipose derived stroma/stem cells sue, administered intramuscularly in patients with critical leg ischemia.

This study will treat patients with such severe lower leg ischemia or vascular compromise that they have pain at rest. The goal is to compare treatment of the patient's painful disorder by injecting cells into the calf of the leg and testing for circulatory improvement. A treatment will given at random to two groups and will be injection into the calf muscle with ALD-301 (specially processed stem and progenitor cells) from the patient's own bone marrow, or with cells processed by more routine that minimally purifies the cells. The study goal is to see if the ALD-301 cells are more effective in generating new small blood vessels to improve the circulation to the affected leg.

Patients with peripheral artery disease have decreased blood flow to exercising muscle causing pain. This decreased blood flow to the muscle affects the level of acylcarnitines which in turn decreases the level of carnitine. Carnitine allows muscles to function properly. This study will test the safety and efficacy of Propionyl-L-Carnitine taken in combination with a monitored exercise training program.

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.
