Brief Summary

To date, antiviral treatment is not recommended for chronic hepatitis B patients with a normal ALT level and low viremia. The strategy is to closely monitor the patients. However, evidence suggests that these group are at risk of gradual disease progression and development of hepatocellular carcinoma. Peginterferon eliminates the hepatitis B virus through immune regulation and induction of antiviral protein expression. For patients with low viral load, the clinical cure rate is potentially promising. In this study, we aim to investigate the efficacy and safety of peginterferon alpha-2b therapy in selected chronic hepatitis B patients with normal ALT level and low viremia. It is expected to obtain a satisfactory curative effect. Peginterferon is a marketed drug available in Chinese clinics with indications of anti-hepatitis B virus.

Study Groups

monotherapy group

Peginterferon alpha-2b injection is given subcutaneously at a dosage of 180μg/w for 48 consecutive weeks. Patients will stop the treatment whenever HBsAg is eliminated, and those without HBsAg elimination after 48 dosages will enter the group of best treatment. The patients will be followed up for another 24 weeks after treatment.
