Active clinical trials for "Hypercholesterolemia"

Assess the efficacy of WelChol® plus Zetia® in treating patients with high cholesterol

The retinal vasculature is morphologically and functionally related to the cerebral vessels due to its common origin from the internal carotid artery. A recent study demonstrated that endothelium-dependent vasodilation of the retinal vasculature is impaired in patients with essential hypertension, which is a strong risk factor for stroke. Furthermore, AT1-receptor blockade was demonstrated to improve retinal endothelium-dependent vasodilation in these hypertensive patients. Hypercholesterolemia is also a risk factor for ischemic stroke and impairment of endothelial function has been observed in various vascular beds in hypercholesterolemic patients, including the coronary and the forearm vasculature. Whether endothelial function of the retinal vasculature is impaired in patients with hypercholesterolemia has not yet been investigated. In patients with stroke, AT1-receptor blockade and angiotensin-converting enzyme inhibition have beneficial effects on clinical outcome. Alterations of endothelial function of the cerebral vasculature might be one pathogenetic factor for the beneficial clinical outcome. To further address this issue, the present study was designed to test the hypothesis that endothelium-dependent vasodilation of the retinal vasculature is impaired in hypercholesterolemic patients and that endothelial function can be improved by AT1-receptor blockade.

This study will evaluate the lipid-lowering effect and safety of colesevelam therapy administered to heterozygous familial pediatric patients 10 through 17 years of age who are on a stable dose of a pediatric-approved statin monotherapy (atorvastatin, lovastatin, simvastatin or pravastatin), or who are treatment naive to lipid-lowering therapy.

The Torcetrapib project was terminated on December 2, 2006 due to safety findings. To evaluate the efficacy and safety of torcetrapib/atorvastatin compared to atorvastatin alone in patients with heterozygous familial hypercholesterolemia

The purpose of the study is to assess the safety and efficacy of fluvastatin in children diagnosed with heterozygous familial hypercholesterolemia

The Torcetrapib project was terminated on December 2, 2006 due to safety findings. To look at ultrasound images taken in the carotid arteries and to look at various lipids in the blood of people with heterozygous familial hypercholesterolemia

The purpose of this study is to evaluate the safety and effectiveness of two approved drugs in lowering high cholesterol when taken together, compared to taking only one of the drugs.

The purpose of this study is to evaluate the cholesterol lowering effectiveness and safety of two investigational drugs in patients with mixed hyperlipidemia (high cholesterol and high triglycerides).

The purpose of this study is to determine to what degree Hypocol® (Red Yeast Rice) may lower low density lipoprotein (LDL)-cholesterol in a European population. The effect of Red Yeast Rice on fasting blood glucose and inflammatory markers will also be investigated.

This is a randomized, double-blind, controlled, parallel-group, multicenter, Phase-3 study to evaluate the efficacy and safety of ezetimibe with simvastatin taken alone in subjects ages 10-17 years with Heterozygous Familial Hypercholesterolemia.
