The ACCELERATE trial investigated the effects of the CETP inhibitor evacetrapib on cardiovascular outcomes. It found that while evacetrapib significantly increased HDL-C and decreased LDL-C, it did not reduce the risk of major cardiovascular events compared to placebo. Multivariable analyses showed that the changes in lipids induced by evacetrapib were not significantly associated with cardiovascular outcomes. The trial demonstrates that favorable changes in lipids alone through CETP inhibition are not sufficient to improve clinical outcomes in high-risk patients receiving standard treatment.
