About this study

Official title: An Open-Label Long-Term Extension to the Randomized, Double-blind, Placebo-controlled, Multi-center, Cross-over Study of Rosuvastatin in Children and Adolescents (Aged 6 to <18 Years) With Homozygous Familial Hypercholesterolemia (HoFH)

The purpose of the study is to evaluate the safety of Rosuvastatin in Children and Adolescents with Homozygous Familial Hypercholesterolemia.

Read the detailed description

This is a long-term extension (LTE) to the randomized, double-blind, cross-over study of rosuvastatin 20 mg once daily (QD) versus placebo QD in children and adolescents (aged from 6 to <18 years) with homozygous familial hypercholesterolemia (HoFH) (Study D3561C00004).

The study is designed to assess the long-term safety and tolerability of rosuvastatin 20 mg in pediatric patients with HoFH.

In this study all patients will receive rosuvastatin 20 mg QD. Investigators will also be permitted to titrate the dose of rosuvastatin from 20 to 40 mg per day if they feel it is warranted to more aggressively treat patients' elevated LDL-C levels. This up-titration will not be permitted in Asian patients. Pharmacokinetic data of the trough plasma exposure of rosuvastatin will also be assessed for the pediatric patients with HoFH taking a daily dose of rosuvastatin 40 mg.

The primary outcome measures to be assessed include 1) Adverse events, including:

  • The frequency and severity of adverse events,
  • Rate of discontinuations due to adverse events,
  • Abnormal serum and urine laboratory values, electrocardiograms (ECGs), physical examinations, and vital signs; and 2) Assessments of growth.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Rosuvastatin 20mg in people with Homozygous Familial Hypercholesterolemia (HoFH), run by AstraZeneca at 6 sites in 6 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 12 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 27 Feb 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Belgium, Canada, Denmark, Israel, Malaysia and 1 more country. 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 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 27 Feb 2018). 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?

The Number of Participants Who Experianced Adverse Events and Serious Adverse Events (time frame: 96 weeks). The study lists 44 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 27 Feb 2018.
