Goal Achievement After Utilizing an Anti-PCSK9 Antibody in Statin Intolerant Subjects-4

Summary

The primary objective of the study was to evaluate the effect of 12 weeks of subcutaneous (SC) evolocumab compared with ezetimibe, on percent change from baseline in low-density lipoprotein cholesterol (LDL-C) in hypercholesterolemic adults unable to tolerate an effective dose of a statin.

Detailed description

After screening participants who met all inclusion/exclusion criteria were randomized with an allocation ratio of 2:2:1:1 into 4 groups: evolocumab (AMG 145) 420 mg administered by subcutaneous injection monthly and placebo pill daily; evolocumab 140 mg administered by subcutaneous injection every two weeks and placebo pill by mouth daily; placebo 420 mg administered by subcutaneous injection monthly and ezetimibe 10 mg pill daily; placebo 140 mg administered subcutaneous injection every two weeks and ezetimibe 10 mg pill daily. Randomization was stratified by screening LDL-C level and baseline statin use. Participants on low or atypical statin dose therapy must have been on a stable dose for at least 4 weeks prior to screening and throughout the blinded portion of the study; the dose could not be adjusted during screening and for the duration of the study. After Week 12, ezetimibe was discontinued and participants moved to an open-label dose of evolocumab administered by subcutaneous injection either every two weeks or monthly and their standard of care.
