Evolocumab reduces first MACE in high-risk patients without established atherosclerosis: Subgroup analysis from the VESALIUS-CV trial

20 Jul 2026

STUDY DESIGN

VESALIUS-CV was a randomized, double-blind, placebo-controlled, multicenter trial conducted across 33 countries that enrolled 12,257 patients to evaluate the impact of evolocumab on major adverse cardiovascular events (MACE) in patients at high cardiovascular (CV) risk without prior myocardial infarction (MI) or stroke.1

Eligible patients were required to have elevated atherogenic lipids, defined as low-density lipoprotein cholesterol (LDL-C) ≥90mg/dL, non-high-density lipoprotein cholesterol (non-HDL-C) ≥120mg/dL, or apolipoprotein B (ApoB) ≥80mg/dL, despite optimized lipid-lowering therapy (LLT) with or without ezetimibe, and had either established atherosclerosis or high-risk diabetes.1 Patients were randomized 1:1 to receive subcutaneous evolocumab 140mg every two weeks or a matching placebo, on top of optimally tolerated statin therapy, and were followed for a median of 4.6 years.1

The present prespecified subgroup analysis focused on 3,655 patients (30% of the overall VESALIUS-CV population) without established significant atherosclerotic disease to assess whether evolocumab could prevent a first MACE in this lower-risk subgroup.1 Significant atherosclerosis was defined as prior arterial revascularization, documented arterial stenosis ≥50%, and a coronary artery calcium (CAC) score ≥100 Agatston units.1 Per protocol, all patients had high-risk diabetes mellitus, defined by a disease duration of ≥10 years, daily insulin use, or the presence of microvascular complications.1

Baseline characteristics within the prespecified subgroup were generally well balanced between treatment groups, with a median age of 65 years and 57% of participants being female.1 Hypertension was present in 88% of patients, with a median body mass index (BMI) of 31kg/m2 and a median LDL-C level of 132mg/dL.1 At baseline, 89% of patients were receiving any LLT, with statins used in 84% and ezetimibe in 14%.1 Of these, 68% were already treated with high-intensity LLT.1

The dual primary endpoints were 3-point MACE (time to coronary heart disease death, MI, or ischemic stroke) and 4-point MACE (time to 3-point MACE or ischemia-driven arterial revascularization).1 Secondary endpoints included composite outcomes of MI, stroke, ischemia-driven revascularization (IDR), and coronary heart disease (CHD)/CV death, along with all-cause mortality.1

FINDINGS

Primary endpoints:

  • The dual primary endpoints were 3-point MACE (time to coronary heart disease death, MI, or ischemic stroke) and 4-point MACE (time to 3-point MACE or ischemia-driven arterial revascularization [IDR])1
  • In the prespecified subgroup, evolocumab reduced the incidence of 3-point MACE by 31% at 5 years vs. placebo (5.0% vs. 7.1%; HR=0.69; 95% CI: 0.52-0.91; p=0.009)1
  • A similar reduction in 4-point MACE was observed in the subgroup with evolocumab vs. placebo (7.6% vs. 10.5%; HR=0.69; 95% CI: 0.55-0.86; p=0.001)1

Secondary and exploratory endpoints:

  • Secondary endpoints included composite outcomes of MI, stroke, IDR, and CHD/CV death, along with all-cause mortality1
  • In the lipid substudy, evolocumab reduced median LDL-C level to 44mg/dL at 96 weeks vs. 105mg/dL in placebo1
  • Evolocumab reduced CV death by 32% (2.6% vs. 4.0%; HR=0.68; 95% CI: 0.46-0.99; nominal p=0.046) and all-cause mortality by 24% (7.8% vs. 10.1%; HR=0.76; 95% CI: 0.61-0.95; nominal p=0.017)1
  • Consistent reductions were observed across secondary composite endpoints and individual components, including MI, IDR, CHD death, and ischemic stroke1
  • Analyses were consistent with the Cholesterol Treatment Trialists’ Collaboration (CTTC) paradigm, demonstrating that reductions in major coronary and vascular events were proportional to the magnitude of LDL-C lowering1
  • A delayed treatment benefit was observed in patients without known atherosclerosis, with minimal event curve separation in the first year followed by substantial risk reduction thereafter; as evident by evolocumab reducing 3-point MACE by 41% and 4-point MACE by 39% from year 1 onwards in the subgroup, in contrast to earlier and more consistent benefit observed in those with established disease1

 

“These data strongly support that in these lower-risk patients, we should be targeting LDL-C goals typically reserved for very high-risk secondary prevention patients.”
