What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent Change From Baseline in Low-Density Lipoprotein Cholesterol (LDL-C) at 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.

    Measured: Baseline and Week 12

  2. Percent Change From Baseline in LDL-C at Week 12: Ezetimibe Alone Versus Evolocumab + Ezetimibe

    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.

    Measured: Baseline and Week 12

    Measured: Baseline and Week 12

  7. Percent Change From Baseline in Total Cholesterol/HDL-C Ratio at Week 12

    LS means are based off an ANCOVA model which includes treatment group (3 evolocumab alone dose groups and the ezetimibe group) and stratification factors as covariates.

    Measured: Baseline and Week 12

  8. Percent Change From Baseline in Total Cholesterol/HDL-C Ratio at Week 12: Ezetimibe Alone Versus Evolocumab + Ezetimibe

    LS means are based off an ANCOVA model which includes treatment group (evoloumab + ezetimibe and ezetimibe alone) and stratification factors as covariates.

    Measured: Baseline and Week 12

  9. Percent Change From Baseline in Apolipoprotein B/Apolipoprotein A1 Ratio at Week 12

    LS means are based off an ANCOVA model which includes treatment group (3 evolocumab alone dose groups and the ezetimibe group) and stratification factors as covariates.

    Measured: Baseline and Week 12

  10. Percent Change From Baseline in Apolipoprotein B/Apolipoprotein A1 Ratio at Week 12: Ezetimibe Alone Versus Evolocumab + Ezetimibe

    LS means are based off an ANCOVA model which includes treatment group (evoloumab + ezetimibe and ezetimibe alone) and stratification factors as covariates.

    Measured: Baseline and Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Evolocumab and Ezetimibe in people with Hyperlipidemia, run by Amgen at 42 sites in 8 countries.

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

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. 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 7 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 42 sites in United States, Spain, Sweden, Australia, Canada and 3 more countries. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 Week 12 (time frame: Baseline and Week 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?

On the ClinicalTrials.gov record for NCT01375764, which also lists 1 linked publication.

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 7 Nov 2022.
