Active clinical trials for "Hyperlipoproteinemia Type II"

Primary Objective: To evaluate the effect of alirocumab on low-density lipoprotein cholesterol (LDL-C) levels after 8 weeks of treatment in heterozygous familial hypercholesterolemia (heFH) participants aged of 8 to 17 years, with LDL-C >=130 milligrams per deciliter (mg/dL) (3.37 millimoles per litre [mmol/L]) on optimal stable daily dose of statin therapy +/- other lipid modifying therapies (LMTs) or a stable dose of non-statin LMTs in case of intolerance to statins for at least 4 weeks prior to the screening period. Secondary Objective: To evaluate the safety and tolerability of alirocumab. To evaluate the pharmacokinetics profile of alirocumab. To evaluate the effects of alirocumab on other lipid parameters.

The purpose of this study is to assess the safety, tolerability, and efficacy of ALN-PCSSC in participants with homozygous familial hypercholesterolemia.

Primary Objective: To evaluate the efficacy of alirocumab (75 or 150 milligrams [mg] depending on body weight [BW]), administered every 2 weeks (Q2W), on low-density lipoprotein cholesterol (LDL-C) levels at Week 12 of treatment in children and adolescents with homozygous familial hypercholesterolemia (hoFH) of 8 to 17 years of age on top of background treatments. Secondary Objectives: To evaluate the efficacy of alirocumab after 24 and 48 weeks of treatment on LDL-C levels. To evaluate the effects of alirocumab on other lipid parameters (eg, apolipoprotein B [Apo B], non-high density lipoprotein cholesterol [non-HDL-C], total cholesterol [Total-C], high density lipoprotein cholesterol [HDL-C], lipoprotein a [Lp (a)], triglycerides [TG], apolipoprotein A-1 [Apo A-1] levels) after 12, 24, and 48 weeks of treatment. To evaluate the safety and tolerability of alirocumab up to 48 weeks of treatment.

This study will assess the safety and tolerability of Ezetimibe (EZ) 10 mg/Atorvastatin (Atora) 10 mg and EZ 10mg/Atora 20 mg fixed-dose combination (FDC) in Japanese participants with hypercholesterolemia uncontrolled with monotherapy of Ezetimibe 10 mg or Atorvastatin up to 20 mg. There is no formal hypothesis for the study.

Familial hypercholesterolemia (FH) is an autosomal codominant single-gene disorder caused by mutations in the LDL receptor gene that disrupt the normal clearance of LDL particles from the plasma compartment. Heterozygous patients present a 2- to 3-fold raise in plasma LDL-cholesterol (C) concentrations, tendinous xanthomatosis and premature atherosclerotic coronary heart disease (CHD), usually occurring between the age of 35 and 55 years. Since the mid-1970s, LDL-C has been removed from the blood of patients using plasmapheresis, and this technique has been shown to improve the life expectancy of FH homozygotes. LDL apheresis selectively removes LDL particles but not immunoglobulins and other beneficial proteins, thereby overcoming a potential drawback of the traditional plasmapheresis method. LDL-C is effectively reduced by more than 60% immediately after LDL apheresis, although LDL levels rebound rapidly. Dextran sulfate adsorption is a commonly apheresis technique used in familial hypercholesterolemia patients. In this apheresis plasma is separated from red blood cells and passed over columns of cellulose beads containing dextran sulfate which binds apolipoprotein B (apoB) by a highly selective electrostatic binding mechanism. Since LDL, very-low density lipoprotein (VLDL), and Lipoprotein (a) all contain apoB, dextran sulfate adsorption apheresis selectively reduces these lipoproteins while having little effect on the non-apoB containing HDL particles. In clinical practice, LDL apheresis reduces the rate of future cardiovascular events and has been postulated to have additional effects on potentially pro-atherogenic factors. Some proteins have been identified with adhesive characteristics to lipoproteins, rheological, immunological and inflammation relevant proteins16-19 that influence microcirculation as well as the inflammatory response. However, no studies have yet to investigate the impact of LDL apheresis on the expression of different genes involved in cardiovascular disease. The main objective of the present research project is to investigate the impact of the LDL apheresis dextran sulfate adsorption system on the messenger ribonucleic acid (mRNA) expression of genes involved in cardiovascular disease using microarrays analysis in 9 FH homozygotes.

The study will assess the safety and tolerability of Ezetimibe 10 mg+ Rosuvastatin 2.5 mg and Ezetimibe 10 mg+ Rosuvastatin 5.0 mg for up to 52 weeks in Japanese participants with hypercholesterolemia uncontrolled with monotherapy of Ezetimibe 10 mg or Rosuvastatin up to 5 mg.

This study is being carried out to see if the study medication, rosuvastatin, is effective in treating familial hypercholesterolaemia in children and adolescents, and to determine the long term (over 2 years) safety, tolerability and efficacy of the study medication in these patients. This study will also measure levels of drug in the blood and see how well it is tolerated. This is known as pharmacokinetic (PK) analysis. At baseline only a small number of patients will participate in a single dose PK phase over 24 hours. In order to see if this medication works, a control group of healthy siblings will help the researchers to compare certain results.

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.

To demonstrate the effect of JTT-705 doses from 300 mg to 900 mg on the elevation of HDL-C and on the inhibition of CETP activity versus placebo, in patients presenting with mild dyslipidaemia. These objectives will be tested after 4 weeks of treatment.

The purpose of this study is to evaluate the effect of two dose levels of JTT-705 when co-administered with pravastatin 40 mg on HDL-C and LDL-C and the inhibition rate of CETP activity and to document short term safety.
