About this study

Official title: Hepatitis B Virus Vaccination in HIV-positive Patients and Individuals at High Risk for HIV Infection: an Open-label Randomized Clinical Trial

The primary aim of this open-label, randomized control trial is to compare the immunogenicity at week 28 after 20µg HBV vaccine (at week 0, 4, 24) versus 40µg HBV vaccine (40-µg at week 0, 4, 24 week) among HIV-positive patients or HIV-negative MSM who were born in Taiwan after July 1986 and tested negative for all HBV serological markers. The secondary aims are to assess the safety of double-dose HBV vaccination, the proportions of high-level responders (anti-HBs antibody >100 mIU/ml) at weeks 28 and 48, the serological responses at week 48, and incident HBV infection (indicated by appearance of anti-HBc and/or HBsAg) at week 48.

Read the detailed description
  1. Study procedures:
  2. Well explain, complete inform and consent documents
  3. A blood test for hepatitis B surface antigen (HBsAg), anti-hepatitis B surface antibody (anti-HBs antibody), anti-hepatitis B core antibody (anti-HBc antibody), anti-HCV and RPR will be performed first.
  4. The patients with all negative seromarkers (within 1 month) will be allocated to two groups (random blank=4), a standard-dose booster of 20µg and a double-dose booster of 40µg. For patients receiving 40µg, two 20µg of vaccines are injected at both sides of deltoid muscles. The schedules of booster vaccination are the same in two groups, which is at 0, 1, 6 months.
  5. To detect and manage possible immediate and severe allergic reaction, patients who received vaccination will be observed for 30 minutes after injection.
  6. The solicited adverse effect will be recorded on the diary card if occurred in 7 days after each dose of vaccination.
  7. The titer of hepatitis B surface antibody will be examined before booster vaccination, at the 4th week, the 24th week, 28th week, 48th week. By comparing the responses in the two groups, the effect of different doses of booster vaccination can be evaluated. For those HIV-negative individuals at baseline, HIV screening test will be evaluated every 6 months during the study, at the 24th week, the 48th.
  8. To screen the acquisition of hepatitis B, the anti-HBc antibody and HBsAg will be examined at the 48th week
  9. To screen the acquisition of hepatitis C and syphilis, anti-HCV and RPR will be examined at the 24th week, the 48th week
  10. The results of the study will be informed by phone or the physician during the follow-up care.
  11. The serum/blood samples will be preserved in the research lab of the department of internal medicine and kept for 20 years. During this period, the sample will be applied or used in other studies after the patients and the Research Ethics Committee both agreed.
  12. During the follow-up care, the treatment or record of hospitalization will be recorded or reviewed.
  13. The participants will drop out of clinical trial when protocol violation occurred or the participant is not willing to continue.

What participants receive

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

  • Engerix-BDrug

    The vaccine contains HBsAg which was produced by genetic engineering yeast. It stimulates the active immunity generated by human immune system toward the HBsAg.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Engerix-B in people with Viral Hepatitis B and Immunization; Infection, run by National Taiwan University Hospital at 1 site in Taiwan.

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 6 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 22 May 2020. 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 Taiwan. 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 Chien-Ching Hung, MD, PhD (+886-2-23123456 ext. 67552, hcc0401@ntu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Vaccine efficacy (time frame: week 28). 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 22 May 2020.
