Effectiveness of inhibition of cholesteryl ester transfer protein by JTT-705 in combination with Pravastatin in type II dyslipidemia

The inhibition of cholesteryl ester transfer protein (CETP) has recently been shown to effectively increase high-density lipoprotein (HDL) cholesterol. This study examined the use of the CETP inhibitor JTT-705 combined with pravastatin. In a randomized, double-blind, placebo-controlled trial, 155 patients with type II dyslipidemia using pravastatin 40 mg were treated with placebo or JTT-705 300 or 600 mg. Four weeks of treatment with JTT-705 600 mg led to a 30% decrease in CETP activity (p <0.001), a 28% increase in HDL cholesterol (p <0.001), and a 5% decrease in low-density lipoprotein cholesterol (p <0.03). Combination therapy using JTT-705 and pravastatin effectively increases HDL cholesterol levels and is safe and well tolerated up to 4 weeks of administration. (c) 2005 by Excerpta Medical In

A review of CETP and its relation to atherosclerosis

Although the atheroprotective role of HDL cholesterol (HDL-c) is well documented, effective therapeutics to selectively increase plasma HDL-c levels are not yet available. Recent progress in unraveling human HDL metabolism has fuelled the development of strategies to decrease the incidence and progression of coronary artery disease (CAD) by raising HDL-c. In this quest for novel drugs, cholesteryl ester transfer protein (CETP) represents a pivotal target. The role of this plasma protein in HDL metabolism is highlighted by the discovery that genetic CETP deficiency is the main cause of high HDL-c levels in Asian populations. The use of CETP inhibitors to effectively increase HDL-c concentration in humans was recently published and data with regard to the effect on human atherosclerosis are expected shortly.jlr This review discusses the potential of CETP inhibitors to protect against atherosclerosis in the context of the current knowledge of CETP function in both rodents and human

The cholesteryl ester transfer protein (CETP) TaqIB polymorphism in the cholesterol and recurrent events study: no interaction with the response to pravastatin therapy and no effects on cardiovascular outcome A prospective analysis of the CETP TaqIB polymorphism on cardiovascular outcome and interaction with cholesterol-lowering therapy

AbstractObjectivesOn the basis of quantitative coronary angiography data, the cholesteryl ester transfer protein (CETP) TaqIB gene polymorphism has been postulated to predict the progression of coronary atherosclerosis and response to cholesterol-lowering therapy.BackgroundCholesteryl ester transfer protein mediates the exchange of lipids between anti-atherogenic high-density lipoprotein (HDL) and atherogenic apolipoprotein B containing lipoproteins and therefore plays a key role in human lipid metabolism. Hence, CETP gene polymorphisms may alter susceptibility to atherosclerosis.MethodsTo investigate the significance of the CETP TaqIB gene polymorphism with respect to clinical end points, we used the Cholesterol And Recurrent Events (CARE) cohort. The CARE study was designed to investigate the effect of five years of pravastatin therapy on coronary events.ResultsWe found that the odds ratios for the primary end point were not significantly different from unity for the three genetic subgroups after five years of placebo treatment. Furthermore, pravastatin induced similar changes in total cholesterol, low-density lipoprotein cholesterol, and HDL cholesterol among TaqIB genotypes, and both nonfatal myocardial infarction and deaths from coronary heart disease were reduced to the same extent in all three genotypes.ConclusionsIn the CARE cohort, the CETP TaqIB polymorphism does not predict cardiovascular events or discriminate between those who will or will not benefit from pravastatin treatment
