The Claim

In patients with established atherosclerosis who are already receiving statin therapy, treatment with evolocumab does not significantly increase the risk of hemorrhagic stroke compared to placebo, as demonstrated by a hazard ratio of 1.16 (95% confidence interval: 0.68–1.98) and a p-value of 0.59, indicating no statistically significant difference in the incidence of brain bleeding events between groups.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

For people with hardened arteries who are on cholesterol-lowering drugs, adding a drug called evolocumab doesn’t seem to raise their risk of bleeding in the brain.

See the scientific wording

In patients with established atherosclerosis on statin therapy, evolocumab does not increase the risk of hemorrhagic stroke, with no statistically significant difference observed between treatment and placebo groups (0.21% vs 0.18%; hazard ratio, 1.16 [95% CI, 0.68–1.98]; P = 0.59), suggesting a favorable safety profile regarding bleeding events in the brain.

  1. Study: Stroke Prevention With the PCSK9 (Proprotein Convertase Subtilisin-Kexin Type 9) Inhibitor Evolocumab Added to Statin in High-Risk Patients With Stable Atherosclerosis

    The study looked at whether a drug called evolocumab causes more brain bleeds in patients already on statins, and found no increased risk compared to placebo.
