HBsAg Decline After Pegylated-interferon-α in e Antigen Positive Chronic Hepatitis B With Nucleoside Maintenance

Chronic Hepatitis B Clinical Trial

Official title:
HBsAg Decline and HBeAg Seroconversion Following 48 Weeks Peg-interferon-α Treatment in Patients With e Antigen Positive Chronic Hepatitis B After Nucleoside Analogue Maintenance Therapy Compared to Continuing Nucleoside Analogue Treatment

Clinical Trial Summary

This study proposes to compare the effect of 48 weeks exposure to pegylated interferon alpha vs. nucleoside analogue (NA) on hepatitis B e antigen (HBeAg) seroconversion and HBsAg levels in nucleoside analogue controlled HBeAg-positive chronic hepatitis B (CHB) patients who have an undetectable hepatitis B virus (HBV) viral load at least 1 years.

Clinical Trial Description

Pegylated interferon after long term NA therapy will potentiate the antiviral efficacy directly via its effect on broad antiviral activities and indirectly via activation of innate and adaptive immune responses leading to HBeAg seroconversion and eventually HBsAg loss and/or seroconversion.

This study proposes to compare the effect of 48 weeks exposure to pegylated interferon alpha vs. NA on HBeAg seroconversion and HBsAg levels in NA controlled HBeAg-positive CHB patients who have an undetectable HBV viral load at least 1 years. ;
