Active clinical trials for "Hypercholesterolemia"

Cardiovascular disease (CVD) is associated with high levels of low-density lipoprotein (LDL) cholesterol and low levels of high-density lipoprotein (HDL) cholesterol. CVD results from 'hardening of the arteries' when there is a build-up of cholesterol in the walls of blood vessels. LDL is the main carrier of cholesterol in the body. LDL particles are responsible for transporting cholesterol that is deposited in vessel walls. LDL particles can also be altered in structure and turn into an irritant to the vessel walls. The body responds to the irritating effect of LDL by producing substances that result in inflammation. This sequence of events eventually leads to the vessels becoming permanently damaged. HDL has a protective role in CVD. It is associated with the enzyme paraoxonase which protects the body from the damaging effects of altered LDL particles. Nicotinic acid (niacin) has the ability to lower LDL levels and raise HDL levels thus reducing the incidence of CVD. Our study aims to show that niacin not only has good effects on cholesterol levels but is also able to reduce inflammation. Niacin is often poorly tolerated due to flushing side effect. Tredaptive is a formulation that combines niacin with laropiprant, an agent that reduces flushing hence improving tolerability and compliance. Patients who are receiving cholesterol-lowering medication and whose LDL levels have not reached the recommended target are recruited to the study. The study will be conducted at the Manchester Royal Infirmary. The study has two consecutive 16 week periods. In each period patients will be randomised to either tredaptive or placebo. They will attend for 5 monitoring visits. Apart from the first visit, fasting blood samples will be taken from them during all subsequent visits.

The primary objective is to determine the effect of WelChol tablets on serum lipids, lipoproteins, apolipoproteins, and lipoprotein particle size in patients who were stabilized on simvastatin therapy for at least 4 weeks.

The purpose of this study is to compare the effects of pitavastatin and atorvastatin on adiponectin percentage change in patients with hypercholesteremia comorbid stable CAD.

Patients with coronary heart disease (CHD) or CHD equivalent (e. g. diabetes mellitus) often have abnormalities in lipids (hypercholesterolemia). Besides, hypercholesterolemia is an evident risk factor for atherosclerosis. Hitherto, there are only few studies of patients with primary hypercholesterolemia where the combination therapy with statins (HMG-Co-reductase inhibitors) and ezetimib was investigated. This combination therapy should be more effective in reducing low density lipoprotein cholesterol (LDL-C) and total cholesterol levels compared to monotherapy.

This is a 3-period study. Periods 1 and 2 will evaluate the effects of multiple doses of laropiprant on the antiplatelet effects of clopidogrel and aspirin administered in combination in participants with primary hypercholesterolemia or mixed dyslipidemia. Period 3 will be open-label and will evaluate single dose pharmacokinetics of nicotinic acid and laropiprant components of Tredaptive.

The purpose of this study is to evaluate the effect of SCH 900271 compared to placebo on the reduction of low-density lipoprotein cholesterol (LDL-C) from baseline to 8 weeks of treatment in participants with primary hypercholesterolemia (familial and nonfamilial) or mixed hyperlipidemia. The study will also evaluate the effect of SCH 900271 on non-high density lipoprotein cholesterol (non-HDL-C) and various other lipids and lipoproteins. The safety of SCH 900271 in this participant population will also be evaluated.

The goal of this trial is to study the effects of AEGR-733 on LDL cholesterol, other lipids as well as measures of safety over the long-term.

The purpose of this study is to determine safety and efficacy of mipomersen (ISIS 301012) in the reduction of total cholesterol, low density lipoprotein cholesterol (LDL-C), and apolipoprotein B (apoB) in high risk subjects intolerant to statins.

To compare the efficacy of various doses of rosuvastatin with atorvastatin, pravastatin & simvastatin in reducing levels of low density lipoprotein cholesterol in subjects with hypercholesterolaemia.

The purpose of this study is to determine the safety and tolerability of ezetimibe/simvastatin in patients newly diagnosed with dyslipidemia.
