About this study

Official title: A Randomized, Double-blind, Multicenter Phase II Clinical Trial to Evaluate the Efficacy and Safety of Therapeutic Hepatitis B Vaccine (Mimogen-based) Joint Entecavir in Treating HBeAg Positive Chronic Hepatitis B Patients

The purpose is to evaluate efficacy and safety of therapeutic hepatitis B virus (HBV) vaccine (mimogen-based)) Joint entecavir treatment in chronic hepatitis B patients.

Read the detailed description

Eligible subjects are enrolled and assigned into 2 groups randomly with a 1:1 ratio:

  1. Therapeutic HBV vaccine Joint Entecavir group:Inject εPA-44 900μg at week 0, 3, 6, 9, 12, 15, 18, 21, 24, 28, 32, 36, 40, 44, 48 + Oral intake entecavir 0.5mg per day ;
  2. Empty liposome Joint Entecavir group:Inject empty liposome at week 0, 3, 6, 9, 12, 15, 18, 21, 24, 28, 32, 36, 40, 44, 48 + Oral intake entecavir 0.5mg per day.

The study cycle consists of screening and enrollment period (week -4~0), treatment and follow-up period (week 0-96).

What is being measured

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

  1. Percentage of Participants With HBeAg Seroconversion at Week 48

    Primary endpoint data were summarised under "End of Study",using the last available post-baseline observation(Last Observation Carried Forward,LOCF)

    Measured: 48 weeks

Secondary outcomes (4)
  1. Serological Response

    Serological response at every observation time: serological conversion rate of HBeAg, negative conversion rate of HBeAg, and change of HBeAg.

    Measured: 96 weeks

  2. Virological Response

    Virological response at every observation time: the proportion of patients with serum HBV DNA level reduction to undetectable level, decreased amount of serum HBV DNA compared with the baseline value, and HBV DNA load decrease 2 log scales or HBV DNA level <1.72×104 IU/ml.

    Measured: 96 weeks

  3. Biochemistry Response

    Biochemistry response at every observation time, mean the ALT level reduce to normal.

    Measured: 96 weeks

  4. Histological Response

    Histological response at week 72, mean histological score limited reduce 2 (reduced score 2-5), and no fiber deterioration compare with before treatment.

    Measured: 72 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Therapeutic HBV vaccine and entecavir in people with Chronic Hepatitis B, run by Chongqing Jiachen Biotechnology Ltd. at 15 sites 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 22 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 26 Jun 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 26 Jun 2019). 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?

Percentage of Participants With HBeAg Seroconversion at Week 48 (time frame: 48 weeks). 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 26 Jun 2019.
