About this study

Official title: Investigation on Antiviral Therapy of Peginterferon Alfa-2b in HBeAg Positive Chronic Hepatitis B Patients Based on Detection of Interferon Gene Mutation and Interferon Receptor

The study is to observe the anti-HBV therapeutic effects of peginterferon alfa-2b in chronic hepatitis b patients with e antigen positive based on the detection of interferon gene mutation (IFNA2 p.Ala120Thr) and interferon receptor (IFNAR2) detection.

Read the detailed description

Patients with e antigen positive chronic hepatitis b were enrolled in the study. Age, sex, symptoms (e.g., fever, fatigue, poor appetite, jaundice) were recorded in the study. We also observed the laboratory test results including the levels of white blood cells (WBC), red blood cells (RBC), hemoglobin (HGB), platelet (PLT), alanine transaminase (ALT), aspartate transaminase (AST), hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), hepatitis B e antibody (HBeAb), and hepatitis B virus (HBV) DNA; detection of gene mutation (IFNA2 p.Ala120Thr), levels of interferon receptor (IFNAR2).

Being tested
Entecavir or Tenofovir, Peginterferon Alfa-2B

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Entecavir or TenofovirDrug

    Also called Baraclude, Viread

    Patients in nucleos(t)ide analogues treatment for 12 weeks group will receive nucleos(t)ide analogs therapy (Entecavir tablet 0.5mg/d or Tenofovir tablet 300mg/d) from Week 25th to 36th.

  • Peginterferon Alfa-2BDrug

What is being measured

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

  1. good virologic response

    level of HBsAg is less than or equal to 1500 IU/ml

    Measured: 24th week

Secondary outcomes (2)
  1. common virologic response

    level of HBsAg is more than 1500 IU/ml, also less than or equal to 20000 IU/ml

    Measured: 24th week

  2. bad virologic response

    level of HBsAg is more than 20000 IU/ml, level of HBV DNA is equal to or more than 4.0 log10 IU/ml

    Measured: 24th week

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Entecavir or Tenofovir and Peginterferon Alfa-2B in people with Chronic Hepatitis b, run by Third Affiliated Hospital, Sun Yat-Sen 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 7 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 25 Nov 2016. 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 Wenxiong Xu, Master (+8613760783281, xwx1983@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

good virologic response (time frame: 24th week). 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 25 Nov 2016.
