Study groups in NCT02189603
Study groupRoleWhat they receive
Senior group(over 65 years old)-HEExperimentalAnti-HEV IgG seronegative participants over 65 years old were enrolled. Hepatitis E vaccine, containing 30mcg of HEV239 recombinant antigen adsorbed to alum adjuvant suspended in 0.5ml phosphate buffer, was given at 0, 1, 6m for three doses.
Receives: Biological: Recombinant (E. Coli) Hepatitis E Vaccine
Younger groups(16-65 years old)Active comparatorParticipants aged 16-65 years old were enrolled. Hepatitis E vaccine, containing 30mcg of HEV239 recombinant antigen adsorbed to alum adjuvant suspended in 0.5ml phosphate buffer, was given at 0, 1, 6m for three doses.
Receives: Biological: Recombinant (E. Coli) Hepatitis E Vaccine
Senior group(over 65 years old)-ContNo interventionAnti-HEV IgG seropositive participants over 65 years old were enrolled. This is the safety control group, without any intervention.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants with Serious and Non-Serious Adverse Events

    Any adverse events reported within one month post each vaccination would be recorded, any serious adverse events reported throughout the study would be recorded.

    Measured: From month 0-7

Secondary outcomes (2)
  1. anti-HEV IgG seropositive rate

    Measured: at month 7

  2. GMT of anti-HEV IgG

    Serum sample would be collected at month 7, and geometric mean titer of anti-HEV IgG would be tested

    Measured: 7 month after first vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Recombinant (E. Coli) Hepatitis E Vaccine in people with Hepatitis E, run by Jun Zhang 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 6 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 17 Aug 2018. 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?

Number of Participants with Serious and Non-Serious Adverse Events (time frame: From month 0-7). 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 NCT02189603, 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 17 Aug 2018.
