Study of Low-Density Lipoprotein Cholesterol (LDL-C) Reduction Using Evolocumab (AMG 145) in Japanese Patients With Advanced Cardiovascular Risk

Overview

The primary objective of the study was to evaluate the effect of 12 weeks of subcutaneous evolocumab administered every 2 weeks and once a month, compared with placebo, on percent change from baseline in LDL-C when used in combination with statin therapy in adults with high cardiovascular risk and with hyperlipidemia or mixed dyslipidemia.

After a screening and placebo run-in period, eligible patients were randomized in a 1:1 ratio to 1 of 2 open-label background statin treatments (atorvastatin 5 mg or 20 mg daily \[QD\]) and entered a 4-week lipid stabilization period. After the lipid stabilization period, eligible patients were randomized in a 1:1:1:1 ratio to investigational product (evolocumab or placebo) for the 12-week treatment period. Both randomizations were stratified by subject diagnosis and lipid-lowering therapy as follows: * current or prior diagnosis of heterozygous familial hypercholesterolemia (HeFH) * no diagnosis of HeFH and receiving intensive lipid-lowering therapy * no diagnosis of HeFH and receiving non-intensive lipid-lowering therapy. A participant was considered randomized into the study after successfully completing the screening period, meeting all inclusion/exclusion criteria including meeting final laboratory safety criteria, and undergoing both randomization procedures.
