Chronic Hepatitis B InfectionNCT03210493
The Changes of Treg Cells Frequency and Function During Antiviral Therapy
A study testing Peginterferon Alfa-2a in people with Chronic Hepatitis B Infection, run by Beijing Ditan Hospital at 1 site in China.
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, Treg cells Regulatory T cells played a negative role in immune. Read more about this study

About this study
Official title: The Changes of Treg 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, Treg cells Regulatory T cells played a negative role in immune. This study was aimed at investigating the changes of Treg cells frequency and function, and the expression of costimulatory molecules during Peg-IFN-αand nucleoside analog(ue) therapy.Meanwhile, the investigators wanted to verify whether Peg-IFN-α suppressed the virus, which led to the decline of Treg cells frequency and function;negative regulation of Tregs for immune cells diminished, hence, the function of immune cells recovered.

In hepatitis B infection, Treg cells play an important role in immune regulation.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 Treg cells in the case of hepatitis and the function enhancement of Treg cells during Peg-IFN-α therapy.

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.

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 Treg Cells (time frame: after treatment 24 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 12 Jul 2017.
