About this study

Official title: A Randomized, Double-Blind, Parallel-Group, Placebo-Controlled Efficacy and Safety Study of Ezetimibe Monotherapy in Children (Ages 6 to 10 Years) With Primary Hypercholesterolemia (Heterozygous Familial and Nonfamilial) (Phase 3, Protocol No. P05522)

The purpose of this study is to determine the effect of ezetimibe 10 mg/day compared to placebo on the reduction of low-density lipoprotein cholesterol (LDL-C) from baseline to 12 weeks of treatment in children >=6 to <=10 years old with primary hypercholesterolemia. The study will also evaluate the effect of ezetimibe on total cholesterol (TC), apolipoprotein B (Apo B), high-density lipoprotein cholesterol (HDL-C), non-HDL-C, and triglycerides (TG). The safety of ezetimibe in this subject population will also be evaluated.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing ezetimibe in people with Primary Hypercholesterolemia, run by Organon and Co.

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 2 inclusion and 8 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 21 May 2024. Status can change between updates, so confirm with the study contact before making plans.

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 30 May 2013). 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?

Percentage Change From Baseline in Low-density Lipoprotein Cholesterol (LDL-C) at Week 12 (time frame: Baseline and Week 12). 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 NCT00867165, 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 21 May 2024.
