About this study
Official title: The Efficacy and Safety of IHCs Treated With Pegylated Interferon α2b Based on Pulse Theray or Sequential Therapy
A multicenter, randomized controlled trial design was used to select patients with chronic hepatitis B in the immune control phase (i.e. HBsAg positive, HBeAg negative, normal ALT and HBsAg≤1000IU/ml, HBV DNA≤2000IU/ml) to enter this study, and to compare the feasibility, effectiveness and safety treated with Pegylated Interferon α2b Continuous therapy or Pulse therapy in immune-controlled chronic hepatitis B patients.
Read the detailed description
Patients:chronic hepatitis B in the immune control phase (i.e. HBsAg positive, HBeAg negative, normal ALT and HBsAg≤1000IU/ml, HBV DNA≤2000IU/ml). The study patients were divided into two groups.Group A (PEG IFN α- 2b continuous group): PEG IFN was injected subcutaneously once a week from the first day of baseline α- 2b 180 μg. The total course of treatment should not exceed 96 weeks.Group B (PEG IFN α- 2b pulse group): from the first day of baseline, PEG IFN was injected subcutaneously α- 2b 180 μg. Every 8 weeks of injection, stop for 4 weeks, and conduct it periodically.Two groups at baseline, 4 weeks, 8 weeks, 12 weeks, 24 weeks, 36 weeks, 48 weeks, 60 weeks, 72weeks, 84 weeks, 96 weeks and the 12th and 24th weeks after drug withdrawal, and corresponding examinations were carried out at each follow-up.Check and record adverse events and concomitant medication in detail, and evaluate the compliance of subjects; Blood samples were retained and transported to the laboratory for HBV at baseline, 24 weeks, 48weeks, 72, 96, and 12 and 24 after drug withdrawal.DNA quantification and detection of hepatitis B virus markers.The efficacy and safety were evaluated after the study.

|---|---|---|
| Group A (continuous treatment group) | Experimental | The treatment period is 12 weeks as a treatment unit, starting from the first day of baseline, subcutaneous injection of Peg-IFNα-2b 180μg once a week, the total treatment course does not exceed 96 weeks. During treatment, when any efficacy check point reaches the disappearance of HBsAg with or without the appearance of HBsAb, at least 2 treatment units of consolidation therapy are given and then the drug is discontinued. Observed for 24 weeks after treatment. Receives: Behavioral: continuous treatment |

What is being measured
The primary outcome is the main question the study is designed to answer.
Extent of HBsAg decrease at 48 weeks
Decreasing level and difference of HBsAg in different treatment groups after 48 week treatment
Measured: 48 weeks
Secondary outcomes (2)
HBsAg clearance at the end of 96 weeks of treatment
To determine the response rate will be evaluated by HBsAg loss defined as HBsAg level lower than 0.05 IU/ml after 96 week treatment
Measured: 96 weeks
The decreasing extent of HBsAg level at 96 weeks
Decreasing level and difference of HBsAg in different treatment groups after 96 week treatment
Measured: 96 weeks

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.

How can a doctor refer a patient or contact the research team?
Contact Jia Shang (13938401888, shangjia666@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Extent of HBsAg decrease at 48 weeks (time frame: 48 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 14 Jul 2022.
