What is being measured

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

  1. Number of Subjects With Anti-hepatitis B Surface Antigen (Anti-HBs) Antibody Concentrations as Measured by ELISA Equal to or Above Cut-off Value

    The cut-off value was defined as 100 milli-international units per milliliter (mIU/mL).

    Measured: One month after the challenge dose (Month 1)

  2. Number of Subjects With Anti-hepatitis B Surface Antigen (Anti-HBs) Antibody Concentrations as Measured by ChemiLuminescence ImmunoAssay (CLIA) Equal to or Above Cut-off Value.

    The cut-off value was defined as 100 milli-international units per milliliter (mIU/mL).

    Measured: One month after the challenge dose (Month 1)

Secondary outcomes (7)
  1. Number of Subjects With Anti-HBs Antibody Concentrations as Measured by ELISA Equal to or Above Cut-off Values

    The cut-off values were defined as 3.3 mIU/mL, 10 mIU/mL and 100 mIU/mL.

    Note: the number of subjects with anti-HBs antibody concentrations equal to or above 100 mIU/mL on month post-challenge dose data are presented as a primary outcome measure.

    Measured: Before (Day 0) and one month (Month 1) after the challenge dose

  2. Number of Subjects With Anti-HBs Antibody Concentrations as Measured by CLIA Equal to or Above Cut-off Values

    The cut-off values were defined as 6.2 mIU/mL, 10 mIU/mL and 100 mIU/mL. Note: the number of subjects with anti-HBs antibody concentrations equal to or above 100 mIU/mL on month post-challenge dose data are presented as a primary outcome measure.

    Measured: Before (Day 0) and one month (Month 1) after the challenge dose

  3. Number of Subjects With Solicited Local and General Symptoms

    Solicited local symptoms were pain, redness and swelling. Solicited general symptoms were fatigue, gastrointestinal symptoms, headache and fever.

    Fever was defined as axillary temperature greater than or equal to 37.5 degrees Celsius.

    Measured: During the 4-day (Day 0-3) follow-up period following the challenge dose vaccination

  4. Number of Subjects With Unsolicited Adverse Events (AEs)

    Unsolicited AE covers any AE reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms.

    Measured: During the 31-day (Day 0-30) follow-up period following the challenge dose vaccination

  5. Number of Subjects With Serious Adverse Events (SAEs)

    SAEs assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in disability/incapacity or are a congenital anomaly/birth defect in the offspring of a study subject.

    Measured: After the challenge dose of the vaccine (Day 0) up to the study end (Month 1)

  6. Number of Subjects With Anamnestic Response to the Challenge Dose as Measured by ELISA.

    Anamnestic response was defined as: - At least (i.e. greater than or equal to) a 4-fold rise in post-challenge vaccine dose anti-HBs antibody concentrations in subjects seropositive (i.e. with anti-HBs antibody concentration equal to or greater than 3.3 mIU/mL) at the pre-challenge dose time point. - Post-challenge dose anti-HBs antibody concentrations equal to or greater than 10 mIU/mL in subjects seronegative (i.e. with anti-HBs antibody concentrations less than 3.3 mIU/mL) at the pre-challenge dose time point.

    Measured: One month after the challenge dose (Month 1)

  7. Number of Subjects With Anamnestic Response to the Challenge Dose as Measured by CLIA.

    Anamnestic response was defined as: - At least (i.e. greater than or equal to) a 4-fold rise in post-challenge vaccine dose anti-HBs antibody concentrations in subjects seropositive (i.e. with anti-HBs antibody concentration ≥ 6.2 mIU/mL) at the pre-challenge dose time point. - Post-challenge dose anti-HBs antibody concentrations equal to or greater than 10 mIU/mL in subjects seronegative (i.e. with anti-HBs antibody concentrations < 6.2 mIU/mL) at the pre-challenge dose time point.

    Measured: One month after the challenge dose (Month 1)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Engerix™-B Kinder in people with Hepatitis B, run by GlaxoSmithKline at 24 sites in Germany.

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 8 inclusion and 14 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 20 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in Germany. 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 Mar 2011). 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?

Number of Subjects With Anti-hepatitis B Surface Antigen (Anti-HBs) Antibody Concentrations as Measured by ELISA Equal to or Above Cut-off Value (time frame: One month after the challenge dose (Month 1)). The study lists 2 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 NCT00984139, 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 20 Aug 2018.
