Active clinical trials for "Hypercholesterolemia"

This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group Phase 3 study of Vytorin 10/10 (ezetimibe 10 mg with simvastatin 10 mg), Vytorin 10/20 (ezetimibe 10 mg with simvastatin 20 mg), and Vytorin 10/40 (ezetimibe 10 mg with simvastatin 40 mg) compared to placebo administered daily for 8 consecutive weeks in subjects with primary hypercholesterolemia (LDL-C >3.64 mmol/L [140 mg/dL]). The efficacy of daily Vytorin versus placebo in reducing the concentration of LDL-C will be evaluated, and the efficacy of daily Vytorin versus placebo with respect to change in the concentrations of total cholesterol, triglycerides, and HDL-C will be compared. The safety of Vytorin versus placebo will also be assessed.

This is a double-blind, placebo-controlled study to assess the effectiveness of BiosLife in lowering serum LDL cholesterol and raising HDL cholesterol. BiosLife is a natural supplement (mixed in water and taken twice daily) which contains guar gum and other natural soluble fibers, phytosterols, policosanol, and a proprietary chrysanthemum extract. Approximately 100 subjects with baseline LDL cholesterol of 110-190 mg/dL will be randomized in a 2:1 ratio to BiosLife or a look-alike placebo. Changes in lipids from baseline will be assessed at 6 weeks and 12 weeks.

Patients with homozygous familial hypercholesterolemia has very high serum cholesterol levels despite receiving lipid lowering drugs (e.g. statins, etc). Most of such patients die before the age of 20 due to myocardial infarction, etc. Orthotopic liver transplantation (OLT) is an effective treatment for that. Hepatocyte transplantation is an alternative to OLT that may help to overcome the shortage of donor organs. There have been reports of successful treatment of different kinds of metabolic liver disorders by hepatocyte transplantation. The major problem with hepatocyte transplantation is that the source of hepatocytes is very limited. Bone marrow stem cells are the potential source of hepatocytes. In the in-vitro culture system successful and efficient transdifferentiation of mesenchymal stem cells into hepatocytes has been documented. We have already shown that infusion of mesenchymal stem cells is safe and feasible in cirrhosis (Mohamadnejad M, et al. Arch Iran Med 2007; In Press). In this study, 2 patients with homozygous familial hypercholesterolemia will be included. The bone marrow of healthy volunteers with a normal lipid profile will be taken, then bone marrow mesenchymal stem cells (MSCs) will be cultured, and then MSCs will be trans-differentiate into hepatocytes, and the cells will be infused through the portal vein into the patients. The duration of follow up will be 6 months post-transplantation.

Aspirin resistance is the persistent platelet activation, demonstrated by platelet function tests (1). The hypothesis is that:LDL lowering by statin in patients with aspirin resistance can improve the effect of aspirin due to the potential decreasing of cholesterol content in the platelet membranes. Patients and methods:Forty hypercholesterolemic patients with aspirin resistance after 5 days of treatment with aspirin and high LDL and triglycerides<300 mg/dL, will be enrolled. Ten healthy volunteers will be the control group.

The aim of our study is to Estimate the reduction of LDL by ezetimibe in hypercholesterolemic patients on simvastatin.Investigate the effect of LDL lowering by ezetimibe on platelet activity and LDL tendency to peroxidation in hypercholesterolemic patients on simvastatin therapy The hypothesis is that: LDL lowering by ezetimibe on-top of simvastatin in patients on fixed dose of simvastatin can reduce platelet aggregation, due to the potential decreasing of cholesterol content in the platelet membranes. LDL lowering by ezetimibe can lower LDL tendency to peroxidation.

This is a multicenter study to evaluate the safety and efficacy of ezetimibe/simvastatin versus rosuvastatin in participants with high cholesterol.

The purpose of this study is to assess the safety, tolerability and pharmacodynamic effects on LDL cholesterol (LDL-C)

The purpose of this study is to evaluate the efficacy and safety of atorvastatin 10 mg and ezetimibe 10 mg coadministration in Japanese participants with hypercholesterolemia whose low-density lipoprotein (LDL)-cholesterol levels have not reached the lipid management target value with atorvastatin 10 mg alone, versus increasing the dose of atorvastatin to 20 mg or changing to rosuvastatin 2.5 mg.

The purpose of this study is to characterize three year descriptive growth and development (ie, height, weight, body mass index, Tanner Stage) and efficacy of cholesterol reduction in pediatric subjects with Heterozygous Familial Hypercholesterolemia receiving atorvastatin treatment.

To determine the effects of WelChol tablets on serum lipids, lipoproteins, apolipoproteins, and lipoprotein particle size in patients who were stabilized on atorvastatin therapy for at least 4 weeks.
