Effects of Icosapent Ethyl (Eicosapentaenoic Acid Ethyl Ester) on Atherogenic Lipid/Lipoprotein, Apolipoprotein, and Inflammatory Parameters in Patients With Elevated High-Sensitivity C-Reactive Protein (from the ANCHOR Study)

Icosapent ethyl is pure prescription eicosapentaenoic acid approved at 4 g/day as an adjunct to diet to reduce triglycerides (TG) in adults with TG ≥500 mg/dl. Elevated high-sensitivity C-reactive protein (hsCRP) is associated with increased cardiovascular risk. The 12-week ANCHOR study randomized 702 statin-treated patients at increased cardiovascular risk with TG 200 to 499 mg/dl despite low-density lipoprotein cholesterol (LDL-C) control (40 to 99 mg/dl). This post hoc analysis assessed 246 ANCHOR patients with baseline hsCRP ≥ 2.0 mg/L randomized to icosapent ethyl 4 g/day (n = 126; approved dose) or placebo (n = 120). Without increasing LDL-C, icosapent ethyl significantly reduced median TG (-20%; p < 0.0001), non-high-density lipoprotein cholesterol (-12.3%; p < 0.0001), total cholesterol (-11.1%; p < 0.0001), high-density lipoprotein cholesterol (-5.2%; p = 0.0042), very LDL-C (-21.0%; p < 0.0001), very low-density lipoprotein TG (-22.9%; p < 0.0001), remnant lipoprotein cholesterol (-23.0%; p = 0.0125), apolipoprotein B (-7.4%; p = 0.0021), apolipoprotein C-III (-16%; p < 0.0001), oxidized LDL (-13.7%; p = 0.0020), lipoprotein-associated phospholipase A2 (-19.6%; p < 0.0001), and hsCRP (-17.9%; p = 0.0213) versus placebo, while interleukin-6 and intercellular adhesion molecule-1 were not significantly changed. Eicosapentaenoic acid increased with icosapent ethyl 4 g/day +637% in plasma and +632% in red blood cells versus placebo (both p < 0.0001). Icosapent ethyl exhibited a safety profile similar to placebo. In conclusion, in statin-treated patients with hsCRP ≥ 2.0 mg/L and TG 200 to 499 mg/dl at baseline, icosapent ethyl 4 g/day significantly and safely reduced TG and other atherogenic and inflammatory parameters without increasing LDL-C versus placebo.
