About this study
Official title: Safety and Immunogenicity Study of the Recombinant Hepatitis E Vaccine(Escherichia Coli) Coadministration With Recombinant Hepatitis B Vaccine
This is a open label, randomized phase VI study, to assess the safety and immunogenicity of co-administration of Hepatitis E vaccine with Hepatitis B vaccine. The concomitant group (n =300) received Hepatitis B vaccine concomitantly with Hepatitis E vaccine at day 1 and months 1 and 6; The nonconcomitant group (n =150) received Hepatitis E vaccine at at day 1 and months 1 and 6. Another nonconcomitant group (n=150) received Hepatitis B vaccine at at day 1 and months 1 and 6.
Anti-HEV IgG and HBsAb were determined. Injection-site and systemic adverse events (AEs) were monitored for 30 days after any vaccination; serious AEs were monitored throughout the study.

The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This is a open label, randomized phase VI study, to assess the safety and immunogenicity of co-administration of Hepatitis E vaccine with Hepatitis B vaccine. The concomitant group (n =300) received Hepatitis B vaccine concomitantly with Hepatitis E vaccine at day 1 and months 1 and 6; The nonconcomitant group (n =150) received Hepatitis E vaccine at at day 1 and months 1 and 6. Another nonconcomitant group (n=150) received Hepatitis B vaccine at at day 1 and months 1 and 6.
Anti-HEV IgG and HBsAb were determined. Injection-site and systemic adverse events (AEs) were monitored for 30 days after any vaccination; serious AEs were monitored throughout the study.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing HEV vaccine and HBV vaccine in people with Hepatitis E and Hepatitis B, run by Xiamen Innovax Biotech Co., Ltd 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 5 inclusion and 10 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 4 Dec 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 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?
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?
Adverse reactions/events (time frame: 7 months). 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 4 Dec 2017.
