About this study
Official title: Long-Term Follow Up Study at Years 16-20, to Evaluate the Persistence of Immune Response of GlaxoSmithKline Biologicals' Hepatitis B Vaccine in Newborns of HBeAg+ and HBsAg+ Mothers
The purpose of this study is to evaluate the persistence of anti-hepatitis B surface antigen (anti-HBs) antibodies 16, 17, 18, 19 and 20 years after administration of the first dose of the study vaccine. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
Read the detailed description
The primary study was designed to evaluate the immunogenicity and protective efficacy of hepatitis B vaccine in newborns of HBeAg+ and HBsAg+ mothers in comparison with a historical control group.
The present study is carried out to evaluate the anti-HBs persistence 16-20 years after the first vaccine dose and to further investigate the prevalence and incidence of other hepatitis B markers and the clinical significance of these at all time points from Year 16-20.
No additional subjects will be recruited during this long-term follow-up study and no vaccine will be administered.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Engerix™-BBiological
In the primary study, subjects received HBV (10 milligram) vaccine according to a 0, 1 and 2 month schedule with a booster dose at Month 12. Subjects in the 5-dose vaccination regimen received a booster dose of HBV vaccine at Month 60.
| Study group | Role | What they receive |
|---|---|---|
| HBV-1 Group | Experimental | neonates born to HBsAg+ and HBeAg+ mothers who received a 5-dose vaccination regimen (0, 1 and 2-month schedule with a booster dose at Month 12 and again a booster dose at Month 60) Receives: Biological: Engerix™-B |
| HBV-2 Group | Experimental | neonates born to HBsAg+ and HBeAg+ mothers who received a 4-dose vaccination regimen (0, 1 and 2-month schedule with a booster dose at Month 12) Receives: Biological: Engerix™-B |
| HBV-3 Group | Experimental | neonates born to HBsAg+ and HBeAg- mothers who received a 5-dose vaccination regimen (0, 1 and 2-month schedule with a booster dose at Month 12 and again a booster dose at Month 60) Receives: Biological: Engerix™-B |
| HBV-4 Group | Experimental | neonates born to HBsAg+ and HBeAg- mothers who received a 4-dose vaccination regimen (0, 1 and 2-month schedule with a booster dose at Month 12) Receives: Biological: Engerix™-B |
| HBV-5 Group | Experimental | neonates born to HBsAg- and HBeAg- mothers who received a 5-dose vaccination regimen (0, 1 and 2-month schedule with a booster dose at Month 12 and again a booster dose at Month 60) Receives: Biological: Engerix™-B |
| HBV-6 Group | Experimental | neonates born to HBsAg- and HBeAg- mothers who received a 4-dose vaccination regimen (0, 1 and 2-month schedule with a booster dose at Month 12) Receives: Biological: Engerix™-B |
What is being measured
The primary outcome is the main question the study is designed to answer.
Anti-hepatitis B Surface Antigen (Anti-HBs) Antibody Concentrations
During this follow-up study, it was planned to collect data from Year 16 through to Year 20 after primary vaccination. By the time the study protocol was approved, it was too late to collect data on Year 16. Therefore, the table presents mean concentrations expressed in milli-international units/milliliter (mIU/mL) at years 17, 18, 19 and 20.
Measured: Years 17, 18, 19 and 20.
Prevalence of Serological Markers for Hepatitis B Infection
It was initially planned to collect data from Year 16 through to Year 20 after primary vaccination. By the time the study protocol was approved, it was too late to collect data on Year 16. Only the subjects positive for HBsAg or anti Hepatitis B core antigen (anti-HBc) were tested for HBeAg \& anti-HBe
Measured: Years 17, 18, 19 and 20.
Clinical Review for Hepatitis B Infection Status
Chronic hepatitis B (HB) carrier is defined as positive for anti-HBc AND HBsAg at two or more consecutive time points
Measured: Over the entire 4 year follow up period (17 - 20 years)

Primary outcome
Anti-hepatitis B Surface Antigen (Anti-HBs) Antibody Concentrations
Time frame: Years 17, 18, 19 and 20.
During this follow-up study, it was planned to collect data from Year 16 through to Year 20 after primary vaccination. By the time the study protocol was approved, it was too late to collect data on Year 16. Therefore, the table presents mean concentrations expressed in milli-international units/milliliter (mIU/mL) at years 17, 18, 19 and 20.
Prevalence of Serological Markers for Hepatitis B Infection
Time frame: Years 17, 18, 19 and 20.
It was initially planned to collect data from Year 16 through to Year 20 after primary vaccination. By the time the study protocol was approved, it was too late to collect data on Year 16. Only the subjects positive for HBsAg or anti Hepatitis B core antigen (anti-HBc) were tested for HBeAg \& anti-HBe
Clinical Review for Hepatitis B Infection Status
Time frame: Over the entire 4 year follow up period (17 - 20 years)
Chronic hepatitis B (HB) carrier is defined as positive for anti-HBc AND HBsAg at two or more consecutive time points

What is this clinical trial studying?
A Phase 4 study testing Engerix™-B in people with Hepatitis B, run by GlaxoSmithKline at 1 site in Thailand.
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 0 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 Dec 2016. 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 Thailand. 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?
Yes. Results are posted in the registry (first posted 1 May 2009). 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?
Anti-hepatitis B Surface Antigen (Anti-HBs) Antibody Concentrations (time frame: Years 17, 18, 19 and 20.). The study lists 3 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 NCT00240500, which also lists 2 linked publications.
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 Dec 2016.
