Active clinical trials for "Peripheral Arterial Disease"

Investigators hypothesize that high-dose n-3 polyunsaturated fatty acids (PUFA) oral supplementation will improve will improve systemic inflammation and patency of peripheral vascular intervention (PVI).

The hypothesis being that both aspirin-ticagrelor and ticagrelor monotherapy will be superior to aspirin monotherapy in the reduction of whole blood viscosity at the end of each 4 week treatment period. Study participants will be randomized into 3 groups, and each group will receive each of 3 treatments in the cross-over study. At the end of each individual 4 week treatment period the investigators will determine whether there are differences in low and high shear rate dependent viscosity and investigate the effect of the treatment on peripheral arterial blood flow using pulse volume recordings, ankle brachial index and toe pressures. Subjects will be eligible if they have ankle-brachial index less than or equal to 0.85, or if a patient's blood vessels are calcified, patients will have toe-brachial index less than or equal to 0.6 performed using continuous-wave Doppler.

Sarpogrelate hydrochloride, a selective 5-HT2A antagonist, has been widely used as an anti-platelet agent for the treatment of PAD. DP-R202 is a new Sarpogrelate hydrochloride product improved patient's convenience and disadvantage of dosage regimen of previous drug. The aim of this study was to compare the efficacy and safety of DP-R202 and Anplag® Tab in patients with PAD

To assess the safety and effectiveness of adventitial deposition of the Study Drug in reducing inflammation and restenosis in patients with clinical evidence of claudication or critical limb ischemia and an angiographically significant lesion in the superficial femoral and/or popliteal arteries. Study Drug and Dose: Dexamethasone Sodium Phosphate Injection, USP, 4 mg/ml, with dilute contrast (17%) administered to the adventitia in a dose of 1.6 mg per cm of desired vessel treatment length.

The purpose of this study is to determine if it is safe and feasible to apply PRT-201 to the adventitia of arteries following successful angioplasty (PTA).

The purpose of this study is to collect safety and efficacy data on the IN.PACT Admiral™ Drug Eluting Balloon (DEB) in treatment of atherosclerotic disease in the superficial femoral and/or popliteal arteries in a "real world" patient population.

This clinical study is being conducted to assess the safety and determine the maximum tolerated dose (MTD) of PDA-002 [human placenta-derived cells] administered into the lower leg muscles of subjects with peripheral arterial disease and diabetic foot ulcers. It will look to see if PDA-002 helps reduce some of the symptoms of PAD and/or improves ulcer healing. This study will also help to find the best dose of PDA-002 to use in future studies.

The Zilver® PTX® V Clinical Study is a post-market clinical trial required by the US FDA to provide continued evaluation of the safety and effectiveness of the Zilver PTX Drug-Eluting Peripheral Stent in treatment of narrowing of the femoropopliteal arteries.

Stimulation of arterial inflow to the lower limb is important to obtain functional improvement in peripheral artery diseased (PAD) patients with claudication. The clinical effect of muscle stimulation to increase arterial inflow and the direct evaluation of the regional blood flow impairment (RBFI) in the area of stimulation, have not been evaluated in PAD patients. Fifteen adult patients with stable arterial claudication will participate. Recruitment will be performed among patients referred for exercise oxymetry (treadmill: 3.2km.h-1, 10% slope) After two minutes of rest, the gastrocnemius will be stimulated for 20 minutes at an increasing frequency rate with 5 min steps (1 Hz, 1.25 Hz, 1.5 Hz and 1.75 Hz) on the most symptomatic side. The investigators record the tcpo2 value, arterial blood inflow with ultrasound of the femoral artery, and near infra-red spectrometry (NIRS) on both sides. Patients will be instructed to report eventual contraction-induced pain in the stimulated calf.

Background and rationale: In clinical practice, antihypertensives are generally prescribed for use in the morning, whereas some statins are recommended for use in the evening. There is evidence that the reduction in LDL cholesterol achieved with some statins is superior when taken in the night, but it is unclear whether the additional reduction in LDL cholesterol(and the reported improvement in BP control when aspirin is taken in the evening) is offset by a reduction in adherence when taking medication in the evening. Current product labelling recommends night use for simvastatin and does not state a timing preference for aspirin or blood pressure lowering medicines. There is therefore uncertainty concerning the best timing of administration of the polypill. This uncertainty will be addressed by this trial. Trial design: Randomised, open label cross over trial (n=75) of the polypill in the morning compared with the evening administration compared with individual agent administration (acetylsalicylic acid and blood pressure lowering agents in the morning, and statin in the evening) in individuals at high risk of cardiovascular disease. Patients will be recruited to the RHP 2c (acetylsalicylic acid 75mg, simvastatin 40mg, lisinopril 10mg, hydrochlorthiazide 12.5mg), and will be randomly allocated to the sequence of time of administration.
