About this study

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

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.

Read the 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.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Atorvastatin and Evolocumab in people with Hyperlipidemia or Mixed Dyslipidemia at High Risk for Cardiovascular Events, run by Amgen at 54 sites in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 54 sites in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Dec 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percent Change From Baseline in Low-Density Lipoprotein Cholesterol (LDL-C) at the Mean of Weeks 10 and 12 (time frame: Baseline and Weeks 10 and 12). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Dec 2015; AzTrials last refreshed its copy on 30 Oct 2026.
