Cholesteryl ester transfer protein (CETP) inhibitor.
Torcetrapib is a Cholesteryl ester transfer protein (CETP) inhibitor. CETP normally transfers cholesterol from HDL cholesterol to very low density or low density lipoproteins (VLDL or LDL). Inhibition of this process results in higher HDL levels (the "good" cholesterol-containing particle) and reduces LDL levels (the "bad" cholesterol). Unfortunately clinical trials were stopped because of excessive all cause mortality. Reasons are still being investigated, but may be related to some off target effects such as an increase in aldosterone secretion not found in some other CETP inhibitors.

Development of the cholesteryl ester transfer protein (CETP) inhibitor, torcetrapib, was halted after the ILLUMINATE trial revealed an increase in both all-cause mortality (ACM) and major cardiovascular events (MCVEs) associated with its use. We now report that the harm caused
Torcetrapib, a cholesteryl ester transfer protein (CETP) inhibitor which raises high-density lipoprotein (HDL) cholesterol and reduces low-density lipoprotein (LDL) cholesterol level, has been documented to increase mortality and cardiac events associated with adverse effects. However, it is still unclear the
Subnormal levels of HDL cholesterol constitute a major cardiovascular risk factor. Inhibitors of cholesteryl ester transfer protein (CETP) are presently the most potent HDL-raising agents. Torcetrapib was the first CETP inhibitor to enter a large-scale, prospective, placebo-controlled interventional trial, which
Aldosterone, sodium, and hypertension: lessons from torcetrapib?
Expert opinion on investigational drugs, 17(10), 1589-1597 (2008-09-24)
Despite reduction in low-density lipoprotein cholesterol, there is still a considerable amount of residual atherosclerosis-related disease. Epidemiological and pathophysiological data strongly favour increasing plasma high-density lipoprotein (HDL) cholesterol levels as antiatherogenic therapy, for example with cholesteryl ester transfer inhibition (CETP).
