Active clinical trials for "Peripheral Vascular Diseases"

This study is a randomized, open-label, blinded endpoint, parallel-group, active-control, multi-center, proof-of-concept study in subjects with Peripheral Arterial Disease (PAD), designed to assess the safety and potential efficacy of adding edoxaban to aspirin following femoropopliteal endovascular intervention, with or without stent placement, relative to current treatment practice with clopidogrel and aspirin.

Peripheral arterial disease (PAD) is a pathological condition limiting, resulting from a narrowing or occlusion of the artery diameter due to aneurysms, inflammation, atherosclerosis and thromboembolic events. One of the main risk factors for the development of DAP is diabetes mellitus due to its relation to the process of atherogenesis. Thus, the objective of this study is to evaluate the effects of three treatment modalities for PAD on the blood flow velocity. It is a crossover study. Fifteen women with diabetes receive three types of treatment, the order defined according draw: high voltage electrical stimulation, shortwave diathermy and kinesiotherapy. The blood flow of the lower limb will be assessed by Doppler ultrasound. The hypothesis of this study is that physical therapy resources increase the circulation of the lower limb.

Cardiovascular disease remain one of the leading causes of death in Australia, accounting for 47637 (36%) of deaths in 2004. Peripheral arterial disease (PAD) is a category of cardiovascular disease, characterised by intermittent claudication. This is defined as walking induced pain, cramping, aching, tiredness or heaviness in one or both legs that does not go away with continued walking and is relieved with rest. It is estimated that between 5-10% of individuals aged over 50 years suffer from claudication. The primary and most effective treatment for these patients is focused on improving walking ability and functional status. Current research has shown that approximately 30% of patients improve with exercise, while 30% continue to deteriorate and the rest show no change. The changes produced at a biochemical and cellular level due to exercise are unknown. To help better understand this, our study will assess the entire range of proteins expressed before and after exercise in the skeletal muscle tissue of patients with intermittent claudication. This will help to identifying key proteins that have a role in improving patient symptoms and outcome.

The primary objective of the Phase I ascending dose trial is to investigate the safety and tolerability of intramuscular (gastrocnemius) injections of human neural stem cell product, CTX, in patients with peripheral arterial disease (Fontaine Stage II through IV). This trial is based on independent preclinical data from a leading academic research institution that has been submitted for publication. Inclusion of patients with Fontaine Stage II is justified as these patients have a lower incidence of background events and will facilitate distinction between events which are possibly intervention-related versus spontaneous events associated with underlying advanced atherosclerosis. The trial is designed to treat 9-18 patients and evaluate safety measures over a 12 month follow-up period.

A primary therapeutic goal for patients with intermittent claudication (IC) is to regain lost physical function through exercise rehabilitation. Supervised exercise programmes can markedly improve walking capacity, but these are resource intensive, National Health Service provision is limited, and patients cite accessing services as a barrier to participation. Increasing walking activity via a structured education programme might be a pragmatic solution for improving walking capacity, health and wellbeing in patients with IC; however, further research is needed to substantiate this. Hence, the aim of this project is to develop a pragmatic education programme to increase walking in these patients and to collect data on its feasibility to inform the development of a definitive trial investigating clinical and cost effectiveness. Focus groups will be conducted to inform the development of the education programme. Programme components will be theoretically-underpinned and evidence-based. The development of the programme will be an iterative process involving pilot work, feedback, evaluation, and revision. The programme will then be assessed in a randomised controlled pilot study with 6-week follow-up (n=30). We will assess the feasibility of the intervention and obtain preliminary data of its impact on important outcomes (daily steps/physical activity, walking capacity, quality of life, illness perceptions).

The PROPEL study will test the hypothesis that GM-CSF combined with supervised treadmill exercise will significantly improve functional performance in patients with PAD more than GM-CSF alone or supervised treadmill exercise alone. In addition to identifying novel therapeutic options for patients with PAD, the current proposal is expected to identify mechanisms by which functional impairment is improved in patients with PAD.

The DURABILITY Iliac study is a prospective, multi-center, non-randomized study confirming the safety and effectiveness of stenting using the Protégé® EverFlex™ and Protégé® GPS™ Self-Expanding Stent Systems for the treatment of atherosclerotic lesions in the common and/or external iliac arteries.

The purpose of the ESPRIT I Clinical Investigation is to evaluate the safety and performance of the ESPRIT BVS in subjects with symptomatic claudication from occlusive vascular disease of the superficial femoral (SFA) or common or external iliac arteries.

Peripheral Arterial Disease (PAD) is a highly prevalent public health problem that results from progressive atherosclerosis of arteries in the lower extremities. PAD is also associated with major detrimental effects on quality of life and functional status, and is the most important cause of limb amputation. More importantly, PAD is a major manifestation of cardiovascular disease and a potent predictor of myocardial infarction, stroke and death. Despite its frequent occurrence, little is known about the natural history of PAD in Hispanics who represent 12.5% of the United States. Because access to health care is limited among Hispanics, CBPR is the ideal process to reach this target population. The goal of the proposed study is to evaluate community-based strategies of detection and treatment of peripheral arterial disease (PAD) in Hispanics. The proposed project consists of two phases: a cross-sectional phase (PAD detection), followed by a randomization phase.During the PAD detection study , the prevalence and severity of PAD in this population will be determined. Specific risk factors associated with PAD among the Hispanic participants will be identified. During the second phase patients will be enrolled in a randomized, non-blinded trial comparing a community-based risk factor modification and supervised exercise program versus usual care for PAD. These individuals will undergo a baseline evaluation similar to the one obtained during the first phase of the study, but will also include functional testing of the lower extremities.

The objective of this post-market clinical follow-up study is to evaluate the clinical outcomes of patients receiving PhotoFix as a patch within a vascular repair or reconstruction procedure.
