To Study the Effect of Adding on Pegylated Interferon (PEG-INF) Therapy for Patients Diagnosed With Chronic Hepatitis B

Summary

To assess whether PEG-INF (Peglyated - interferon) Add-on therapy in patients of CHB who have achieved a maintained viral suppression (HBV DNA PCR( polymerase chain reaction) \<200 for last 3-6 month) with NA's can result in increased rate of HBV infection eradication (HbsAg is undetectable by serological blood testing with or without seroconversion to HBs antibody).
