Study on Clinical Program Optimization of Inactive Hepatitis B Surface Antigen (HBsAg) Carriers (IHCs)

Overview

A multicenter, randomized controlled trial design was used to select patients with chronic hepatitis B in the immune control phase (i.e. HBsAg positive, HBeAg negative, normal ALT and HBsAg≤1000IU/ml, HBV DNA≤2000IU/ml) to enter this study, and to compare the feasibility, effectiveness and safety treated with Pegylated Interferon α2b Continuous therapy or Pulse therapy in immune-controlled chronic hepatitis B patients.

Patients:chronic hepatitis B in the immune control phase (i.e. HBsAg positive, HBeAg negative, normal ALT and HBsAg≤1000IU/ml, HBV DNA≤2000IU/ml). The study patients were divided into two groups.Group A (PEG IFN α- 2b continuous group): PEG IFN was injected subcutaneously once a week from the first day of baseline α- 2b 180 μg. The total course of treatment should not exceed 96 weeks.Group B (PEG IFN α- 2b pulse group): from the first day of baseline, PEG IFN was injected subcutaneously α- 2b 180 μg. Every 8 weeks of injection, stop for 4 weeks, and conduct it periodically.Two groups at baseline, 4 weeks, 8 weeks, 12 weeks, 24 weeks, 36 weeks, 48 weeks, 60 weeks, 72weeks, 84 weeks, 96 weeks and the 12th and 24th weeks after drug withdrawal, and corresponding examinations were carried out at each follow-up.Check and record adverse events and concomitant medication in detail, and evaluate the compliance of subjects; Blood samples were retained and transported to the laboratory for HBV at baseline, 24 weeks, 48weeks, 72, 96, and 12 and 24 after drug withdrawal.DNA quantification and detection of hepatitis B virus markers.The efficacy and safety were evaluated after the study.
