Main results


In the REVEAL study, individuals with diabetes were at higher absolute risk of major coronary events. Anacetrapib lowered non-HDL-c and reduced major coronary events with similar efficacy in patients with and without diabetes. Patients with diabetes had a numerically greater absolute risk reduction with anacetrapib treatment. A small reduction in risk of new-onset diabetes mellitus was observed.


Discussant Stephen Nicholls (Adelaide, Australië) summarized in his presentation what we know about CETP: it plays an important role in lipid metabolism, and genetic polymorphisms associated with low CETP activity associate with low CV risk. CETP inhibitors gained popularity primarily due to their ability to raise HDL-c levels and because CETP inhibition showed favorable effects on animal models of atherosclerosis. Favorable effects on HDL-c and LDL-c levels have indeed been demonstrated in humans, but torcetrapib also produced adverse effects on mortality and CV events. Dalcetrapib and evacetrapib trials were stopped early due to clinical futility.

Anacetrapib is a more potent CETP inhibitor. The CV benefit observed associated with the reduction in atherogenic apoB containing lipoproteins. The authors now demonstrate similar benefits in patients with and without diabetes and that a lower rate of new onset diabetes in patients treated with anacetrapib.

The modest CV benefit and prolonged half-life led to the decision to not bring anacetrapib to the clinic. However, he said, the benefit does keep the door slightly open with regard to potential clinical use of these agents in higher risk patients with higher baseline LDL-C levels. Genetic studies report that CETP inhibition may be of more value in the absence of statin therapy and that dalcetrapib may have benefits exclusively in patients with specific polymorphisms.

Considering lipid modifying therapy in the context of diabetes, evidence from genetics suggests that lowering LDL-C will associate with a greater risk of diabetes. The clinical relevance is unknown and are unlikely to change treatment of high risk patients in which the benefits of lipid lowering are well established. While CETP inhibitors in general have favurable effects on the risk of developing diabetes, it remains unknown how this influences clinical outcomes
