What is being measured

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

  1. The Number of Seroprotected Participants to the Modified Process Hepatitis B Vaccine and ENGERIX-B™ (Currently Licensed Vaccine) at Month 7

    The number of participants as measured by the

    seroprotection rate (anti-hepatitis B surface antibodies greater than or equal to 10 mIU/mL). Anti-HBs (Antibodies against hepatitis B surface antigen) titers were measured from blood samples taken at Day 1 (prior to the first dose) and at Month 7 (1 month after the third dose).

    Measured: 7 months (1 month after the third dose)

  2. The Number of Seroprotected Participants to the Modified Process Hepatitis B Vaccine and ENGERIX-B™ (Currently Licensed Vaccine) at Month 9

    The number of participants as measured by the

    seroprotection rate (anti-hepatitis B surface antibodies greater than or equal to 10 mIU/mL). Anti-HBs (Antibodies against hepatitis B surface antigen) titers were measured from blood samples taken at Day 1 (prior to the first dose) and at Month 9 (1 month after the fourth dose).

    Measured: 9 months (1 month after the fourth dose)

  3. The Total Number of Participants With One or More Injection-Site Adverse Experiences

    Measured: Days 1-15 After Any Vaccination

  4. The Total Number of Participants With a Maximum Temperature >= 100.0F / 37.8C

    Measured: Days 1-5 After Any Vaccination

  5. The Total Number of Participants With Serious Vaccine-Related Clinical Adverse Experiences

    Participants with adverse experiences considered possibly, probably, or definitely related to study vaccines and considered serious (death, persistent disability, life threatening, hospitalization, birth defects, cancer, or overdose).

    Measured: 0-9 months (recorded from first dose until the participant completes or discontinues the study)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Comparator: modified process hepatitis B vaccine and Comparator: ENGERIX-B™ in people with Hepatitis B Virus Infection, run by Merck Sharp & Dohme LLC.

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: finished, as of the sponsor's last update on 13 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

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 8 Jul 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?

The Number of Seroprotected Participants to the Modified Process Hepatitis B Vaccine and ENGERIX-B™ (Currently Licensed Vaccine) at Month 7 (time frame: 7 months (1 month after the third dose)). The study lists 5 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 NCT00440297, 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 13 Apr 2017.
