About this study
Official title: A Study of Peg-interferon Treatment for Nucleos(t)Ide Analogues Suppressed Chronic Hepatitis B Patients With Low Level Hepatitis Surface Antigen
Chronic hepatitis B is a global public health problem, with nearly 700,000 deaths each year because of hepatitis B-related diseases. Recent studies have found that some patients who have used nucleot(s)ide analogues(NAs) for some period can achieve higher hepatitis B surface antigen(HBsAg) clearance rate(which is called clinical cure or functional cure) by using pegylated interferon. Patients who achieve clinical cure will further reduce liver inflammation, fibrosis and risks of liver cirrhosis and cancer in the future. This study was initiated in May 2018 and plans to recruit 30,000 eligible patients. The enrollment conditions are as follows: 1. according with the diagnosis of chronic hepatitis B in the guideline of China in 2015; 2.18-60 years old; 3. more than 1 year history of NAs therapy with HBsAg ≤1500 IU/ml, negative hepatitis e antigen and hepatitis B virus DNA<100 IU/ml; 4. no contraindications of interferon. For the above patients, pegylated interferon was used for 1-2 years(combined with NAs for at least 3 months).The primary goal of this study is to find out the optimal treatment for clinical cure.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Chronic hepatitis B is a global public health problem, with nearly 700,000 deaths each year because of hepatitis B-related diseases. Recent studies have found that some patients who have used nucleot(s)ide analogues(NAs) for some period can achieve higher hepatitis B surface antigen(HBsAg) clearance rate(which is called clinical cure or functional cure) by using pegylated interferon. Patients who achieve clinical cure will further reduce liver inflammation, fibrosis and risks of liver cirrhosis and cancer in the future. This study was initiated in May 2018 and plans to recruit 30,000 eligible patients. The enrollment conditions are as follows: 1. according with the diagnosis of chronic hepatitis B in the guideline of China in 2015; 2.18-60 years old; 3. more than 1 year history of NAs therapy with HBsAg ≤1500 IU/ml, negative hepatitis e antigen and hepatitis B virus DNA<100 IU/ml; 4. no contraindications of interferon. For the above patients, pegylated interferon was used for 1-2 years(combined with NAs for at least 3 months).The primary goal of this study is to find out the optimal treatment for clinical cure.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing pegylated interferon-alfa in people with Hepatitis B, Chronic, 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 4 inclusion and 13 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: under way, not looking for participants, as of the sponsor's last update on 13 Apr 2025. 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?
This study is still under way. Results are not available in the source record yet.
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?
hepatitis B surface antigen (time frame: up to 48 weeks). 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 NCT04035837, which also lists 14 linked publications.
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 13 Apr 2025.
