About this study

Official title: Cohort Study on Efficacy and Safety of Interferon Intermittent Treatment of Chronic Hepatitis B

This study was a retrospective clinical observational cohort study. All patients with chronic hepatitis B (CHB) whose HBsAg decreased by less than 10% were treated continuously with interferon in the Department of Hepatology, Beijing Ditan Hospital, Beijing Medical University, Beijing Capital University, 2008.10-2017.4. The total interferon treatment time of the enrolled subjects was 48 weeks. The subjects were randomly divided into the following two observation cohorts: 1) patients with chronic hepatitis B treated with continuous interferon for 48 weeks; 2) intermittent interferon For 48 weeks of treatment for patients with chronic hepatitis B, the interferon treatment interval was 3 months. HBV DNA content, HBsAg/anti-HBs, HBeAg/anti-HBe and biochemical markers, serum AFP and liver imaging (liver ultrasound) were collected before treatment (baseline) and during treatment. The primary outcome measure was the rate at which HBsAg disappeared at 48 weeks of treatment. The secondary evaluation index was the 48-week HBeAg seroconversion rate. To investigate the efficacy, influencing factors and safety of interferon intermittent treatment of chronic hepatitis B.

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?

Rate of disappearance of HBsAg (time frame: after 48 weeks of treatment). 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 NCT04028856, 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?
