What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Blood samplingProcedure or surgery
At Years 16 - 20 after first dose of the primary vaccination in HAB-084 (208127/084) study.
| Study group | Role | What they receive |
|---|---|---|
| 2-dose Primed Group | Experimental | Adolescent subjects in this group received 2 doses of Twinrix Adult (720/20) (licensed as Ambirix in the EU) according to a 0, 6 months schedule in the primary study HAB-084 (208127/084). Receives: Procedure: Blood sampling |

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

Measured: At each long-term follow-up (LTFU) visit (16-20 years after the first dose of primary vaccination)
Secondary outcomes (1)
Occurrence of Serious adverse events (SAEs)
Measured: During the entire study period (Year 16-20)

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Blood sampling in people with Hepatitis B and Hepatitis A, run by GlaxoSmithKline at 1 site in Czechia.
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 3 inclusion and 7 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The record says: withdrawn, as of the sponsor's last update on 18 Nov 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Czechia. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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The study was withdrawn before enrolling participants, so there are no results.
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?
Immunogenicity with respect to components of the study vaccine in terms of antibody titres (time frame: At each long-term follow-up (LTFU) visit (16-20 years after the first dose of primary vaccination)). 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 18 Nov 2015.
