An Open-label Trial of 48-week Peginterferon Alfa-2a (PEGASYS) to Assess the Sustained Response of Chronic Hepatitis B Patients With HBeAg Seroconversion on Nucleot(s)Ide Analogue Therapy

Summary

This is a multi-center, single-arm, open-label study on the virological response of chronic HBV infection to pegyinterferon-alfa-2a among patients who achieved HBeAg seroconversion on nucleos(t)ide analogue (NA) treatment. The primary endpoint of this study is to investigate the sustained response (HBeAg seroconversion with HBV DNA \<2000 IU/ml) to peginterferon at 24 weeks after the end of treatment.
