  Purpose
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.

Study Type: Interventional
Study Design: Allocation: Randomized

Primary Purpose: Treatment
Official Title: A Double-blind, Randomized, Placebo-controlled, Multicenter Study to Evaluate Safety, Tolerability and Efficacy of Evolocumab (AMG 145) on LDL-C in Combination With Statin Therapy in Japanese Subjects With High Cardiovascular Risk and With Hyperlipidemia or Mixed Dyslipidemia

Detailed Description:

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.
