A Study on the Pursuit of Sustained Clearance of HBsAg in Chronic Hepatitis B(CHB) Patients With Previous Interferon Treatment Using Pegylated Interferon Alpha
This is a real-world, prospective, multicenter, non-randomized, controlled study. It aims to investigate the efficacy and safety of pegylated interferon α-2b (PEG IFN α-2b) monotherapy versus its combination with nucleos(t)ide analogs (NAs) regarding hepatitis B surface antigen (HBsAg) clearance in interferon-experienced patients with chronic hepatitis B (CHB). Subjects will receive either interferon-based therapy or NAs monotherapy based on their personal willingness and physicians' professional recommendations, with a uniform 48-week treatment course for all enrolled patients.
