Summary

Studies have shown that chronic hepatitis B patients with low levels of HBsAg after nucleos(t)ide analog therapy have a higher chance of functional cure with sequential or combined pegylated interferon therapy, with about 30-50% of patients achieving HBsAg clearance and discontinuing therapy.

There are some clinical practices on the long-term benefits of discontinuing antiviral therapy, but there is a lack of evidence-based clinical studies, especially on the relapse rate, duration of relapse, and factors influencing relapse after achieving functional cure. Furthermore, there is no guideline or expert consensus on the follow-up management strategy for patients who haven't achieved functional cure but whose HBsAg levels have been substantially reduced by treatment and are at low levels.

Therefore, this study is planned to enroll participants who have completed the TB1901IFN to evaluate the long-term benefit of Peginterferon in combination with tenofovir disoproxil fumarate(TDF) and relapse in patients who have achieved functional cure, for participant with low-level HBsAg at the end of treatment, peginterferon combined with tenofovir alafenamide fumarate (TAF)therapy will be administered to explore the efficacy and safety of starting treatment after a period of drug discontinuation. Participants will be divided into 3 cohorts based on functional achievement and/or HBsAg levels after completion of TB1901IFN
