Update on the Discovery and Development of Cholesteryl Ester Transfer Protein Inhibitors for Reducing Residual Cardiovascular Risk

摘要

Cholesteryl ester transfer protein (CETP) facilitates the transfer of cholesteryl ester and triglycerides between plasma lipoprotein particles HDL and LDL/VLDL, resulting in equilibration between these lipoprotein fractions. Therapy that modulates HDL metabolism to increase HDL-c levels could be an effective strategy to reduce residual cardiovascular risk since it is estimated that for each mg/dL increase in plasma HDL cholesterol, there could be a 2?3% decrease in cardiovascular risk. Modification of the lipoprotein profile by CETP inhibitors is promising, but the beneficial effect of reducing coronary heart disease risk has not yet been proven. To date, four CETP inhibitors have advanced to phase 3 cardiovascular outcome clinical trials, and two have been terminated for off-target adverse effects and lack of efficacy. This perspective will summarize recent events, new research developments, and the discovery of new classes of CETP inhibitors.
