Evolocumab reduced first cardiovascular events

In high-risk diabetes without prior heart attack or stroke, evolocumab lowered major cardiovascular events when added to usual cholesterol treatment.

Background

People with diabetes have higher cardiovascular risk, and lowering low-density lipoprotein cholesterol reduces that risk. This study tested whether adding evolocumab helps prevent first major cardiovascular events in a particularly high-risk diabetes population.

Patients

6,002 adults with high-risk diabetes, defined by small-vessel disease, chronic insulin use, or diabetes duration of at least 10 years. Important exclusions included prior heart attack or stroke.

Intervention

Evolocumab 140 mg injected every 2 weeks, added to optimized cholesterol-lowering therapy.

Control

Matching placebo injection every 2 weeks, added to optimized cholesterol-lowering therapy.

Outcome

Two main composite outcomes: coronary heart disease death, heart attack, or ischemic stroke; and the same outcome plus artery-opening procedures for poor blood flow.

Follow-up Period

Median 4.6 years.

Results

Outcome Evolocumab Placebo Effect NNT
Main 3-part composite (primary) 6.1% 8.4% HR 0.71 (95% CI, 0.59-0.86) 44
Main 4-part composite (primary) 11.7% 14.5% HR 0.79 (95% CI, 0.69-0.91) 36
All-cause death 8.8% 11.0% HR 0.79 (95% CI, 0.67-0.93) 46
Ischemic stroke 2.0% 3.1% HR 0.66 (95% CI, 0.48-0.91) 91

HR = hazard ratio; CI = confidence interval; NNT = number needed to treat over 4.6 years.

Analyses were intention-to-treat. This was not a non-inferiority trial. The control reflected usual optimized cholesterol treatment without evolocumab.

Limitations

This was a subgroup analysis, although prespecified. The “high-risk diabetes” definition may not match all guidelines. About one-third already had atherosclerosis, limiting generalizability. Hemoglobin A1c and diabetes complications during follow-up were not measured. Industry funding and author employment by the manufacturer raise bias concerns.

Funding

Amgen funded; several authors employed by Amgen.

Clinical Application

Consider evolocumab for selected high-risk diabetes patients with persistent elevated cholesterol despite optimized therapy, especially when preventing first cardiovascular events is a priority.
