  • Percent Change From Baseline in Low-Density Lipoprotein Cholesterol (LDL-C) at Week 12 [ Time Frame: Baseline and Week 12 ]
    LDL-C was measured using ultracentrifugation. Least squares (LS) means are based off an analysis of covariance (ANCOVA) model which includes treatment group (3 evolocumab alone dose groups and the ezetimibe group) and stratification factors as covariates.
  • Percent Change From Baseline in LDL-C at Week 12: Ezetimibe Alone Versus Evolocumab + Ezetimibe [ Time Frame: Baseline and Week 12 ]
    LDL-C was measured using ultracentrifugation. LS means are based off an ANCOVA model which includes treatment group (evolocumab + ezetimibe and ezetimibe alone) and stratification factors as covariates.
Percent change from baseline in LDL-C [ Time Frame: 12 week treatment duration ]

Goal Achievement After Utilizing an Anti-PCSK9 Antibody in Statin Intolerant Subjects
A Randomized, Multicenter Study to Evaluate Tolerability and Efficacy of AMG 145 on LDL-C, Compared With Ezetimibe, in Hypercholesterolemic Subjects Unable to Tolerate an Effective Dose of a HMG-CoA Reductase Inhibitor
The primary objective was to evaluate the effect of 12 weeks of subcutaneous evolocumab (AMG 145), compared with ezetimibe, on percent change from baseline in low-density lipoprotein cholesterol (LDL-C) in patients with hypercholesterolemia unable to tolerate an effective dose of a statin.
