Identification of CETP as a Marker of Atherosclerosis

Status Completed

Clinical Trial Summary

The reverse cholesterol transport (RCT) pathway, which involves the centripetal movement of free cholesterol from peripheral tissues, including the vessel wall, to the liver represent the primary mechanism by which HDL protects against atherosclerosis and by which it may induce plaque regression. Recent data reveal that the capacity of HDL to efflux cholesterol from macrophages, a metric of HDL function reflecting the initial step of the RCT, is clinically relevant, displaying a strong inverse association with both carotid intima-media thickness and the severity of angiographic CAD; such observations were independent of HDL-C levels. In human, the Cholesteryl Ester Transfer Protein (CETP), represents a key protein of the RCT pathway and mediates redistribution of neutral lipids between lipoproteins, has been identified as a potential therapeutic target against atherosclerosis. It is known that CETP activity correlates with HDL-C levels and represents a key modulator of the ability of whole plasma to mediate free cholesterol efflux from human macrophages. Recent studies showed that 23% of endogenous plasma CETP activity variability is explained by plasma LDL-C (12.0%), HDL-C (6.4%) and TG (4.4%) whereas sex and BMI accounted together for only 0.7% of its variability. Scoring patients for cardiovascular risk on the basis of their plasma lipid levels (TC, TG, LDL-C and HDL-C), revealed that patients with high cardiovascular risk (score ≥3) displayed a mean endogenous plasma CETP activity above 34%. Therefore plasma CETP activity represents a potent indicator of cardiovascular risk in patients with metabolic disorders since it integrates major independent risk factors. The objective of this study is to decipher the relationship between CETP, HDL efflux capacity and the development of atherosclerosis in humans in order to identify CETP as a potent biomarker of atherosclerosis distribution.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
