Trial summary

Pegylated interferon α-2a(Peg-IFN-α) not only inhibit viral replication, but also play an important role in immune regulation, while Nucleoside analog(ue) drugs only inhibit viral replication. In hepatitis B infection, NKs are the main effector cells in early antiviral innate immune response. Read more about this study

About this study

Official title: The Changes of Natural Killer Cells Frequency and Function During Pegylated Interferon α-2a and Nucleoside Analogues Treatment in Patients With Chronic Hepatitis B.

Pegylated interferon α-2a(Peg-IFN-α) not only inhibit viral replication, but also play an important role in immune regulation, while Nucleoside analog(ue) drugs only inhibit viral replication. In hepatitis B infection, NKs are the main effector cells in early antiviral innate immune response. This study was aimed at investigating the changes of NKs frequency and function, and the expression of costimulatory molecules during Peg-IFN-αand nucleoside analog(ue) therapy.Meanwhile, investigators want to verify whether Peg IFN - alpha suppressed the virus and the reduction of virus led to the recovery of NKs function, or Peg IFN - alpha enhanced NKs function which gave rise to the decline of the virus.

Read the detailed description

Pegylated interferon α-2a(Peg-IFN-α)and Nucleoside analog(ue) drugs can inhibit viral replication , but Peg-IFN-α also play an important role in immune regulation . In hepatitis B infection, NKs are the main effector cells in early antiviral innate immune response.Peg-IFN-α recommended as the first-line treatment has a higher chance to achieve HBeAg seroconversion and even HBsAg disappearance than nucleoside analog(ue) drugs, which may be related to the functional activation of pDCs in the case of hepatitis and the function enhancement of NKs during Peg-IFN-α therapy. This study was aimed at investigating the changes of NKs frequency and function, and the expression of costimulatory molecules during Peg-IFN-αand nucleoside analog(ue) therapy.Meanwhile, investigators want to explore whether the decline of HBsAg and HBeAg resulted in recovery of NKs function, or recovery of NKs function led to the decrease of HBsAg and HBeAg. Several studies demonstrated that HBsAg and HBeAg could damage NKs function, and the loss of HBsAg and HBeAg led to recovery of NKs function.

What participants receive

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

  • Peginterferon Alfa-2aDrug

    Also called Peg-IFN-α

    patients untreated in immune-active phase were given subcutaneous injection of Peginterferon Alfa-2a with starting dose of 180 mg/weekly in experiment group.

What is being measured

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

  1. the changes of Natural Killer Cells

    the changes of NK%,CD56bri/NK%,CD56dim/NK%,IFNAR2+NK%,IFNAR2MFI,NKp46+/NK%,NKp46dim/NK%,NKp46high/NK%, NKp46MFI,and NKp46ABC will be measured by flow cytometry during Pegylated Interferon α-2a and Nucleoside Analogues Treatment

    Measured: at baseline and at treatment week 12, 24

Secondary outcomes (3)
  1. the change of HBVDNA levels (IU/ML)

    the curative effect of antiviral therapy will be evaluated by HBV markers and HBV DNA levels and liver function

    Measured: at baseline and at treatment 12, 24, 36, 48 weeks

  2. the change of ALT levels(U/L)

    the curative effect of antiviral therapy will be evaluated by HBV markers and HBV DNA levels and liver function

    Measured: at baseline and at treatment 12, 24, 36, 48 weeks

  3. the change of AST levels(U/L)

    the curative effect of antiviral therapy will be evaluated by HBV markers and HBV DNA levels and liver function

    Measured: at baseline and at treatment 12, 24, 36, 48 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Peginterferon Alfa-2a in people with Chronic Hepatitis B Infection, run by Beijing Ditan Hospital 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 1 inclusion and 5 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 12 Jul 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yao Xie, MD (8610-84322489, xieyao00120184@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the changes of Natural Killer Cells (time frame: at baseline and at treatment week 12, 24). 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 NCT03208998, 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 12 Jul 2017; AzTrials last refreshed its copy on 2 Nov 2026.
