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

July 13, 2022 updated by: Henan Provincial People's Hospital

The Efficacy and Safety of IHCs Treated With Pegylated Interferon α2b Based on Pulse Theray or Sequential Therapy

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.

Detailed Description

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Group A (continuous treatment group)
The treatment period is 12 weeks as a treatment unit, starting from the first day of baseline, subcutaneous injection of Peg-IFNα-2b 180μg once a week, the total treatment course does not exceed 96 weeks. During treatment, when any efficacy check point reaches the disappearance of HBsAg with or without the appearance of HBsAb, at least 2 treatment units of consolidation therapy are given and then the drug is discontinued. Observed for 24 weeks after treatment.
The treatment period is 12 weeks as a treatment unit, starting from the first day of baseline, subcutaneous injection of Peg-IFN α-2b 180μg once a week, or every 8 weeks of injection, 4 weeks off, periodically, the total treatment course does not exceed 96 weeks.
Experimental: Group B (pulse therapy group)
The treatment period is 12 weeks as a treatment unit. From the first day of baseline, subcutaneous injection of Peg-IFNα-2b 180 μg, every injection for 8 weeks, stop for 4 weeks, periodically, the total treatment course does not exceed 96 weeks.
