Brief Summary
The goal of this clinical trial is to compare sequential PEG-IFNα therapy strategies in chronic hepatitis B (CHB) patients previously treated with ASO/siRNA. The main questions it aims to answer are:
- Group A (immediate 24-week PEG-IFNα + 24-week follow-up) vs. Group B (24-week observation + 24-week PEG-IFNα) in Phase 1 to see if sequential PEG-IFNα therapy will improve HBsAg loss rate . Researchers will describe:
- The response rate of IFN treatment in non-responders (HBsAg-positive) in Phase 2.
- The relaspe rate of responders (HBsAg-negative). Participants will: Phase 1 (0-48 weeks):
- Group A: Receive PEG-IFNα for 24 weeks, followed by 24-week treatment-free follow-up.
- Group B: Undergo 24-week observation, then receive PEG-IFNα for 24 weeks. Phase 2 (48-96 weeks):
- HBsAg-positive at week 48 patients either from group A or group B : Receive 24-week PEG-IFNα therapy, followed by 24-week follow-up.
- HBsAg-negative at week 48 patients either from group A or group B: Enter 24-week follow-up without treatment. All participants will undergo:
- HBsAg quantification, HBV DNA, liver function, and safety monitoring (every 12 weeks).
