Does Evolocumab Lower Lipoprotein Particles?

Am J Cardiol; ePub 2017 Nov 8; Toth, et al

Evolocumab significantly lowers atherogenic lipoprotein particles (LDL-P), including low-density and remnant lipoproteins, a recent study found. The post-hoc sub-analysis included 619 patients from the DECARTES trial, a 52-week, randomized, double-blind, placebo-controlled, global study of patients with hyperlipidemia. At baseline, mean LDL-P concentration was 1,077 nmol/L for the placebo group and 1,100 nmol/L for the evolocumab group. Researchers found:

  • In patients receiving evolocumab, week 52 total LDL-P concentration decreased to 610 nmol/L, a treatment difference of 50% vs placebo.
  • Evolocumab also reduced concentrations of medium VLDL-P, small VLDP-P, and IDL-P.
  • Mean changes in total LDL particle size in the evolocumab group was ‒1.7.
  • Changes in total LDL, HDL, and VLDL particle sizes were all significant vs placebo.
