Trial summary

Intramuscular injection of 40 μg hepatitis B vaccine in a standard three-dose schedule or a four-dose schedule is recommended for hemodialysis patients. However, seroconversion rates are inadequate and persistence of immunity remains a challenge. This is a randomized, controlled trial. Read more about this study

About this study

Official title: Immunogenicity and Persistence of Intramuscular High Dose Recombinant Hepatitis B Vaccine in Hemodialysis Patients in China: a Multicenter Randomized Controlled Trial

Intramuscular injection of 40 μg hepatitis B vaccine in a standard three-dose schedule or a four-dose schedule is recommended for hemodialysis patients. However, seroconversion rates are inadequate and persistence of immunity remains a challenge.

This is a randomized, controlled trial. The study will evaluate the immunogenicity, immune persistence, and safety of 20 µg and 60 µg recombinant hepatitis B vaccine with three injections at months 0, 1, and 6 in hemodialysis patients.

Read the detailed description

Participants are randomized in a ratio of 1:1 into 20 µg recombinant hepatitis B vaccine group or 60µg recombinant hepatitis B vaccine group.The 20 µg group will receive three intramuscular injections of the 20 µg recombinant hepatitis B vaccine, while the 60 µg group will receive three intramuscular injections of the 60 µg dose at months 0, 1 and 6, respectively. HBsAg and anti-HBs will be tested during the study period. Adverse reactions will be recorded after vaccination.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing 60 µg dose hepatitis B vaccine and 20 µg dose hepatitis B vaccine in people with Hepatitis B Vaccine, run by Suping Wang.

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 4 inclusion and 14 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 14 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

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?

Yes. Results are posted in the registry (first posted 14 Feb 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

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 NCT02963714, 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 14 Feb 2022.
