Active clinical trials for "Atherosclerosis"

The purpose of the study is to assess the safety and efficacy of the Lutonix Catheter for treatment of stenosis of the femoropopliteal arteries by direct comparison to standard balloon angioplasty.

The specific aim of the SOS-Xience V study is to examine the 12-month incidence of binary angiographic in-stent restenosis after implantation of the Xience V stent in aortocoronary saphenous vein bypass graft lesions.

Study Goal #1: Determine the optimal oral dose of vitamin C to reduce surrogate markers of atherosclerosis (blockages in blood vessels) following the consumption of an atherogenic high fat lunch in type 2 diabetic individuals. Study Goal #2: After conducting the original study, we found that vitamin E was not effective in reducing the markers of oxidative stress, hypercoagulation, inflammation, and metabolic parameters in patients with type 2 diabetes. To date, data from randomized trials have largely demonstrated no significant benefit of vitamin E supplementation on the prevention of primary and/or secondary cardiovascular disease as once thought. Therefore, we decided to amend our current protocol to add a Part B to study only the effects of vitamin C at the following doses: 500 mg, 1000 mg, and 2000 mg daily (and include a placebo arm, as well.

A 104-week, randomized, double-blind, parallel group, multi-center Phase IIIb study comparing the effects of treatment with rosuvastatin 40 mg or atorvastatin 80 mg on atherosclerotic disease burden as measured by intravascular ultrasound in patients with coronary artery disease.

The purpose of this study is to evaluate the effects of Atorvastatin on the coronary atherosclerosis plaque morphology.

The primary objective of this study is to examine the effects of SB-480848 on plasma lipoprotein associated phospholipase A2 (Lp-PLA2) activity in dyslipidemic patients during a 4-week treatment with SB-480848.

This study will assess whether co-administration of ezetimibe 10 mg with simvastatin 20 mg will be more effective than treatment with simvastatin 20 mg alone in reducing LDL-C concentrations when administered for 6 weeks.

Rationale: Cis-9, trans-11 conjugated linoleic acid (CLA) can protect against the atherosclerosis development in several animal models. Studies in transgenic mice have shown that mechanisms might involve beneficial effects on lipoprotein metabolism and insulin sensitivity and in addition activation of anti-inflammatory pathways. A very limited amount of human studies have not shown similar beneficial effect of cis9,trans11-CLA on insulin sensitivity in obese subjects, yet cis9,trans11-CLA did improve the lipoprotein profile in healthy subjects. The effect of cis9,trans11-CLA supplementation on alternative early biomarkers of atherosclerosis, like aortic pulse wave velocity, and alternative biomarkers identified through platelet proteomics, has not been assessed before, and may add valuable insights into the mechanism of this functional fatty acid in humans. Objective: To assess the effect of increased intake of cis9 trans11-CLA on development of atherosclerosis, as assessed with aortic pulse wave velocity and on alternative biomarkers. Study design: The study is designed as a double blind randomised placebo controlled parallel group trial. Study population: 400 men and women, between 40 and 70 years of age, with a body mass index of 25 kg/m2 or above. Subjects with previous symptomatic vascular disease or diabetes mellitus and subjects on blood pressure lowering or lipid lowering medication are excluded. Intervention: Subjects in the intervention arm will receive daily 4 g of CLA oil (2.6 g cis9,trans11-CLA), 2 capsules to be taken in the morning and 2 in the evening. The subjects in the control arm receive 4 identical placebo capsules. Main study parameters/endpoints: The main study outcome is difference between treatment arms in change in aortic pulse wave velocity after 6 months intervention.

The purpose of this study is to investigate an oral formulation of RVX000222 for safety, pharmacokinetic and efficacy in healthy subjects.

Molsidomine used as an add-on treatment on standard care therapy should be superior to placebo used also as an add-on treatment on standard care therapy on improving the endothelial function (endothelium score measured by reactive hyperemia - peripheral arterial tonometry [RH-PAT]) after 12 months of treatment in patients with stable angina patients and undergoing elective percutaneous coronary intervention. The study will be double-blind, parallel-group, randomised, multicentre, sequential, placebo-controlled study. The device used to determine RH-PAT will be EndoPAT. Duration of the treatment = one year.
