Active clinical trials for "Peripheral Vascular Diseases"

The objective of this clinical investigation is to evaluate the safety and efficacy of the Minnow Medical GRST™ Peripheral Catheter System in the treatment of de novo lesions in the superficial femoral artery (SFA) or the popliteal artery.

A 12-Week Efficacy Study in participants with Peripheral Arterial Disease. the primary hypothesis is that MK-0736 7 mg administered once daily for 12 weeks will result in a decrease in lower extremity atherosclerotic plaque macrophage content when compared to placebo (an approximate decrease of up to 30% is expected).

This is an interventional study assessing the effectiveness of Ticagrelor on the reduction of thrombus burden using optical coherence tomography in patients undergoing peripheral artery stenting.

The PDA-002-DFU-002 trial is a Phase 2, multicenter, randomized, double blind, placebo controlled, dose range finding study. The study will enroll approximately 133 subjects in four treatment groups. The primary objective of the study is to assess the efficacy and safety of PDA-002 administered intramuscular (IM) in subjects who have DFU with and without PAD. The secondary objective is to explore potential clinical efficacy by assessing changes in vascular parameters such as Ankle-Brachial Index and Toe-Brachial Index (ABI and/or TBI), Transcutaneous oxygen measurements (TcPO2).

The purpose of this study is to determine the effects of metformin on functional capacity (pain-free and maximum walking times) in individuals with peripheral artery disease (PAD)-related intermittent claudication.

The primary objective of the VBX 17-04 registry is to collect post-market safety and performance data of the GORE® VIABAHN® VBX Balloon Expandable Endoprosthesis (VBX Stent Graft) in peripheral vessels in patients who require interventional treatment

Peripheral arterial disease (PAD) affects over 8 million individuals in the United States alone. This is a form of atherosclerosis in which plaques preferentially build up inside the arteries of the legs to limit blood flow. These patients are at high risk for heart attack and stroke, with at least half dying from coronary artery disease. Our understanding of the causes of PAD remains incomplete. The renin-angiotensin hormone system is one mechanism known to contribute to atherosclerosis. Pharmacologic blockade of the hormone angiotensin II is beneficial in forms of atherosclerosis, including peripheral arterial disease, to improve blood vessel damage and functional outcomes. These therapies also increase circulating levels of angiotensin-(1-7), a hormone that dilates blood vessels. Angiotensin-(1-7) improves blood vessel function and reduces inflammation to protect against atherosclerosis in animal models; however, there are no clinical data in patients with atherosclerosis. The overall goal of this project is to examine the cardiovascular effects of angiotensin-(1-7) in PAD.

The purpose of this study is to apply Avazzia micro-current stimulation to patients with chronic, non-healing wounds to determine if this therapy is effective in perfusion and bacterial measurements.

Intermittent claudication (IC), the most common manifestation of peripheral artery disease (PAD), represents not only a significant detriment in quality of life, but also an increased risk for atherosclerotic cardiovascular disease (ASCVD), including progression of PAD, coronary artery disease (CAD) and cerebrovascular disease. Guideline directed therapy for IC includes supervised exercise, smoking cessation and optimal medical management to decrease overall risk of ASCVD. In the VA Health Care System, implementation of supervised exercise therapy through cardiac rehabilitation or physical therapy programs is limited by distances that patients must travel to VA facilities that provide these services. Furthermore, one of the most common failure points in exercise therapy programs is poor patient compliance. Improved patient participation and compliance in exercise programs for IC represents an unmet need, without which the majority of patients with life-style limiting PAD may not be receiving optimal medical management. Small studies have demonstrated the effectiveness of home-based exercise programs as an alternative to supervised exercise therapy; however, the success of the home-based exercise programs require remote coaching and/or regular provider feedback. The wide-spread availability of smart phones and smart devices has accelerated the implementation of telehealth programs that may supplement or may eventually replace in-person encounters for health care delivery. The role of provider feedback in addition to real-time feedback from smart devices remains completely unexplored. Our central hypothesis is that in individuals with IC, regular provider feedback on smart-device-based remote health monitoring data, which is available to the patient in real time, will augment the benefits of home-based exercise programs. We propose a randomized trial in patients with IC to test the central hypothesis through two Specific Aims: To determine the effect of provider feedback on smart-device-based remote health monitoring data during home-based exercise programs on walking distance in patients with IC. To determine the effect of provider feedback on smart-device-based remote health monitoring data during home-based exercise programs on quality of life (QOL) in patients with IC. Based on a sample size calculation to detect a 50% increase in walking distance between the 2 groups, we expect to enroll 30 patients (15 in each group). Patient participation in the study will be concluded after 12 weeks. As an exploratory aim in the study, we will also (as an optional part of the study) collect plasma before and after the 12-weeks of exercise to investigate changes in lipid levels and plasma biomarkers associated with exercise therapy. This exploratory aim will generate preliminary data for future studies.

The objective is to ensure the pro-active collection of information on quality, safety and performance of FlowOx™ after it is placed on the market. The study will be carried out in a patient population with peripheral artery disease (claudicatio intermittens) to confirm its usefulness and in particular gather information for further improvements of the device related to this patient population. The data collected from the use of the CE-marked FlowOX™ device are change of walking distance, quality of life, and the patient's compliance.
