About this study

Official title: Immunogenicity and Safety of 4- vs. 3-standard Doses HBV Vaccination in HIV-infected Adults With Isolated Anti-HBc Antibody

The finding of isolated hepatitis B core antibody (isolated HBc) in absent of recent active hepatitis could cause by several scenarios, including false positive, remote infection without viremia, and occult infection with low viremia. Hepatitis B virus (HBV) vaccine booster could be a great prevention strategy for those who do not have HBV viremia. There is no standard consensus for management of this issue especially among HIV infected population. In addition, prior studies revealed that HIV-infected individuals had lower immunologic response to HBV vaccine than general population. This study intends to compare the immune response and safety of 4- versus 3-standard dose of hepatitis B virus vaccination in HIV-infected adults who has isolated HBc. The immunologic response will be evaluated after the participants receive vaccination.

Read the detailed description
  • A randomized controlled trial to evaluate differences in immunogenicity and safety of the two hepatitis B vaccination regimens, including the percentage of responders, high-level responders, anamnestic response, geometric mean titers of anti-HBs antibody, adverse events and predictive factors associated with vaccine responsiveness
  • After participant enrollment, data on baseline characteristics, time since HIV diagnosis, CD4 counts, HIV viral load, antiretroviral treatment regimen and duration will be collected, then the participants will be randomized into 2 groups to receive either 3- or 4-standard doses (20 mcg per dose) of HBV vaccination, and follow-up blood test for anti-HBs titers at multiple pre-specified time points to evaluate outcomes

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Hepatitis B vaccine in people with Hepatitis B Vaccination, HIV, 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 11 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: status not confirmed, as of the sponsor's last update on 11 Jul 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Romanee Chaiwarith, MD (+66-5393-6457, rchaiwar@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Immunologic response to 4 versus 3 doses of HBV vaccination in HIV-infected adults with isolated anti-HBc antibody, demonstrated by percentage of responders (with anti-HBs Ab ≥ 10 mIU/mL ) at week 28 (time frame: 28 weeks after the first dose of HBV 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 NCT03212911, 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 11 Jul 2017.
