About this study

Official title: Comparison of Immunogenicity of Four Doses and Four Double Doses vs. Standard Doses of Hepatitis B Vaccination in HIV-infected Adults: a Result From Randomized Controlled Trial at 3 Years After Vaccination

This is a follow up study from the published article entitled "Comparison of immunogenicity and safety of four doses and four double doses vs. standard doses of hepatitis B vaccination in HIV-infected adults: a randomized, controlled trial" by Chaiklang K, Wipasa J, Chaiwarith R, Praparattanapan J, Supparatpinyo K. that was published in PLoS One. 2013 Nov 12;8(11):e80409. doi: 10.1371/journal.pone.0080409. eCollection 2013. ClinicalTrials.gov; NCT1289106. This study aimed to evaluate the efficacy of the HBV vaccination regimens using either four standard doses or four double doses compared with the current standard regimen of three doses in HIV-infected adults in northern Thailand. In addition, the investigators evaluated the efficacy of the HBV vaccination with the current standard regimen of three doses between healthy adults and HIV-infected patients.

Read the detailed description

From February 4, 2011 to May 4, 2012, 132 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 three recombinant vaccine (Hepavax-Gene® Berna, Korea) regimens: 20 μg IM at months 0, 1, and 6 (Standard doses group, n=44), 20 μg IM at months 0, 1, 2, 6 (four doses group, n=44), or 40 μg IM at months 0, 1, 2, and 6 (four double doses group, n=44). There was another group of healthy individuals received standard dose of 20 μg IM at months 0, 1, and 6 recruited during the same time and under the same protocol. In brief, at months 7 and 12, the percentages of responders (anti-HBs ≥10 mIU/mL) were 88.6% and 70.4% in the Standard doses group, 93.2% and 86.4% in the four doses group, (P=0.713 and 0.119), and 95.4% and 88.6% in the four double doses group, (P=0.434 and 0.062), respectively.

This current study aimed to evaluate the efficacy of the different HBV vaccination regimens at 36 months after vaccination. In addition to compare the group using four standard doses or four double doses with the current standard regimen of three doses in HIV-infected adults in northern Thailand, the investigators also compare the efficacy of the current standard regimen of 3 doses between HIV-infected and healthy individuals.

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 "healthy" v.s. "HIV group 1", "HIV group 2" v.s. "HIV group 1", "HIV group 3 v.s. "HIV group 1"

    Measured: 36 months after vaccination

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

    Comparison of the geometric means of anti-HBS titers between "healthy" v.s. "HIV group 1", "HIV group 2" v.s. "HIV group 1", "HIV group 3 v.s. "HIV group 1"

    Measured: 36 months 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 "healthy" v.s. "HIV group 1", "HIV group 2" v.s. "HIV group 1", "HIV group 3 v.s. "HIV group 1"

    Measured: 36 months after vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing recombinant HBV vaccine (Hepavax-Gene® Berna, Korea) 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 5 inclusion and 4 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. Some participants in this study may receive a placebo. 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: 36 months after vaccination). 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 NCT02713620, 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 19 Apr 2017.
