Assessment of Clinical Effects of Cholesteryl Ester Transfer Protein Inhibition With Evacetrapib in Patients at a High Risk for Vascular Outcomes - ACCELERATE

Contribution To Literature:

The ACCELERATE study suggests that evacetrapib is not superior to placebo in reducing cardiovascular outcomes in patients at high risk for vascular risk despite favorable effects on both high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C).


The goal of the trial was to compare the safety and efficacy of evacetrapib, a cholesteryl ester transfer protein (CETP) inhibitor, in patients at high vascular risk.

Study Design

Patients at high vascular risk were randomized in a 1:1 fashion to either evacetrapib 130 mg daily (n = 6,038) or placebo (n = 6,054).

  • Total number of enrollees: 12,092
  • Duration of follow-up: 30 months
  • Mean patient age: 65 years
  • Percentage female: 23%
  • Percentage diabetics: 68%

Other salient features/characteristics:

  • Prior myocardial infarction (MI): 67%
  • Peripheral arterial disease: 14%
  • High-intensity statin use: 46%
  • Mean LDL-C: 81 mg/dl
  • Mean HDL-C: 45 mg/dl

Inclusion criteria:

  • Acute coronary syndrome (ACS) within 30-365 days          
  • Diabetes with coronary disease
  • Peripheral arterial disease
  • Cerebrovascular disease
  • Must be treated with a statin for at least 30 days prior to screening; or, if not treated with a statin, must have documented statin intolerance or contraindication to statin
  • HDL-C <80 mg/dl
  • Triglycerides ≤400 mg/dl

Exclusion criteria:

  • History of transient ischemic attack (TIA) or ischemic stroke <30 days and ACS <30 days
  • Blood pressure ≥180/110 mm Hg
  • History of hemorrhagic stroke or intracranial hemorrhage
  • New York Heart Association class III or IV congestive heart failure
  • Serum creatinine >2.2 mg/dl
  • Clinically active liver disease
  • History of malignancy within the preceding 3 years prior to screening

Principal Findings:

The trial was terminated early due to futility.

The primary outcome, cardiovascular death/MI/stroke/coronary revascularization/unstable angina for evacetrapib vs. placebo: 12.8% vs. 12.7%, p = 0.85

Components of the primary outcome (for evacetrapib vs. placebo):

  • CV death: 7.2% vs.7.3%, p = 0.73
  • MI: 4.2% vs. 4.2%, p = 0.97
  • Stroke: 1.5% vs. 1.6%, p = 0.82

Secondary outcomes:

  • Mean HDL-C for evacetrapib vs. placebo at 30 months: 104 mg/dl vs. 46 mg/dl, p < 0.001
  • Mean LDL-C at 30 months: 55 mg/dl vs. 84 mg/dl, p < 0.001
  • All-cause mortality: 3.8% vs. 4.1%, p = 0.06
  • Drug discontinuation due to adverse events: 8.6% vs. 8.7%, p = 0.86
  • Change in high-sensitivity C-reactive protein: 4.6% vs. -8%
  • New hypertension: 11.4% vs. 10.1%, p < 0.05. mean difference in systolic blood pressure = 0.9 mm Hg during the trial


The results of this trial indicate that evacetrapib is not superior to placebo in reducing cardiovascular outcomes in patients at high risk for vascular risk despite a 130% increase in HDL-C and a 37% decrease in LDL-C. Reasons for this are unclear, but may be related to a blood pressure increasing effect of these drugs (although it only increased by 1 mm Hg during the trial). Inflammatory markers such as high-sensitivity C-reactive protein were also elevated with evacetrapib. This trial, coupled with negative results for torcetrapib and dalcetrapib, suggests that CETP inhibition may not be a good strategy to mitigate residual cardiovascular risk. An outcomes trial with anacetrapib is ongoing.
