About this study
Official title: A Prospective Study on the Immunogenicity and Persistence of Hepatitis B Vaccine in Methadone Maintenance Treatment Patients
At present, Methadone Maintenance Treatment Patients of Hepatitis B Vaccination in are vaccinated with hepatitis B vaccine according to the standard three-dose schedule immunization program, and the effect of preventing HBV infection is not ideal.
This is a randomized, controlled trial. The study will evaluate the immunogenicity and persistence of 20 µg and 60 µg recombinant hepatitis B vaccine with three or four injections at months 0, 1, and 6 or 0, 1,2, and 6 in Methadone Maintenance Treatment Patients
Read the detailed description
Participants are randomized in a ratio of 1:1:1 into 20 µg recombinant hepatitis B vaccine group at months 0, 1, and 6 or 20µg recombinant hepatitis B vaccine group at months 0, 1, 2, and 6 or 60µg recombinant hepatitis B vaccine group at months 0, 1, 2, and 6. HBsAg and anti-HBs will be tested during the study period. Adverse reactions will be recorded after vaccination.

This is a randomized, controlled trial. The study will evaluate the immunogenicity and persistence of 20 µg and 60 µg recombinant hepatitis B vaccine with three or four injections at months 0, 1, and 6 or 0, 1,2, and 6 in Methadone Maintenance Treatment Patients
Detailed description
Participants are randomized in a ratio of 1:1:1 into 20 µg recombinant hepatitis B vaccine group at months 0, 1, and 6 or 20µg recombinant hepatitis B vaccine group at months 0, 1, 2, and 6 or 60µg recombinant hepatitis B vaccine group at months 0, 1, 2, and 6.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing 20 µg recombinant hepatitis B vaccine at months 0, 1, and 6, 20 µg recombinant hepatitis B vaccine at months 0, 1, 2, and 6 and 60 µg recombinant hepatitis B vaccine at months 0, 1, 2, and 6 in people with Hepatitis B Vaccine, run by Shanxi Medical University at 1 site in China.
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 2 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 24 May 2019. 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 China. 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 Suping Wang, PhD (#86-351-4135103, spwang88@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Anti-HBs Seroconversion Rate at Month 7 (time frame: Month 7). 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 NCT03962816, which also lists 2 linked publications.
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 24 May 2019.
