About this study

Official title: Evaluate the Persistence of Immune Response of GSK Biologicals' TWINRIX™ ADULT, Administered According to 0,6 Month Schedule and 0,12 Month Schedule, in Volunteers Aged 12-15 Years Inclusive at the Time of First Vaccine Dose

To evaluate the persistence of immune response 5 years and 6 years after the first vaccine dose.

Read the detailed description

Open, randomised, long-term antibody persistence studies, conducted in 2 centers. Immune persistence was compared between subjects who received two doses of GSK Biologicals combined hepatitis A and hepatitis B vaccine at either 0, 6 month schedule or 0, 12 month schedule. These long-term follow-up studies involved taking blood samples at approximately 5 and 6 years after the primary vaccination of combined hepatitis A and B vaccine, to assess antibody persistence and a retrospective safety follow-up.

What is being measured

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

  1. Immune persistence in terms of anti-HAV and anti-HBs antibodies and GMCs, 5 and 6 years after administration of first vaccine dose. An additional dose of the study vaccine will be given (between 6 to 12 months after the Year 6 time point) to subjects who

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Combined Hepatitis A and B vaccine in people with Hepatitis B and Hepatitis A, run by GlaxoSmithKline at 2 sites in Australia.

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 1 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?

The record lists 2 sites in Australia. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Immune persistence in terms of anti-HAV and anti-HBs antibodies and GMCs, 5 and 6 years after administration of first vaccine dose. An additional dose of the study vaccine will be given (between 6 to 12 months after the Year 6 time point) to subjects who. 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.
