About this study

Official title: Comparison of Immunogenicity and Safety of 4 Standard Doses and 3 Standard Doses of Hepatitis B Vaccination in HIV-infected Adults Who Have CD4 < 200 Cells/mm3

This study aimed to evaluate the efficacy of different hepatitis B vaccination regimens in HIV-infected adults with low CD4 cell count in northern Thailand.

Read the detailed description

HIV-infected adults with CD4+ cell counts < 200 cells/mm3, undetectable plasma HIV-1 RNA, and negative for all HBV markers were randomly assigned to receive one of these 2 regimens of recombinant hepatitis B vaccine (Centro De Ingenieria Genetica Y Biotecnologia, La Habana, Cuba); 1) 20 μg IM at months 0, 1, and 6 (3-standard doses group), and 2) 20 μg IM at months 0, 1, 2, 6 (4-standard doses group).

This study aimed to evaluate the efficacy and safety of these 2 hepatitis B vaccination regimens at month 7 after vaccination.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Recombinant Hepatitis B vaccine [(CIGB) La Habana, Cuba]Biological

    Different HBV vaccine regimen in each group

Study groups in NCT02732054
Study groupRoleWhat they receive
HIV-Group 1Active comparatorReceiving three intramuscular injections of 20 µg of recombinant hepatitis B vaccine [(CIGB) La Habana, Cuba] at months 0, 1, and 6
Receives: Biological: Recombinant Hepatitis B vaccine [(CIGB) La Habana, Cuba]
HIV-Group 2ExperimentalReceiving four intramuscular injections of 20 µg of recombinant hepatitis B vaccine [(CIGB) La Habana, Cuba] at months 0, 1, 2, and 6

What is being measured

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

  1. Proportion of participants with protective immunity against HBV

    comparison of proportion of participants who had protective immunity (anti-HBS titer >=10 mIU/ml) against HBV between HIV group 2 v.s. HIV group 1

    Measured: 1 month after vaccination

Secondary outcomes (2)
  1. The geometric means of anti-HBs titers

    Comparison of the geometric means of anti-HBS titers between HIV group 2 v.s. HIV group 1

    Measured: 1 month after vaccination

  2. Proportion of participants with high level of immune response against HBV

    Comparison of proportion of participants who had anti-HBS titers >= 100 mIU/ml between HIV group 2 v.s. HIV group 1

    Measured: 1 month after vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Recombinant Hepatitis B vaccine [(CIGB) La Habana, Cuba] in people with Hepatitis B, run by Chiang Mai University 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 11 inclusion and 5 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 19 Apr 2017. 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?

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?

Proportion of participants with protective immunity against HBV (time frame: 1 month after 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 19 Apr 2017.
