실험적: Sequential PD-1 Antibody and Peg-IFNα
Participants will continue background nucleos(t)ide analogue therapy throughout the study.
During Weeks 0-12, participants will receive the PD-1 antibody plus NAs.
Peg-IFNα will be added at Week 12, resulting in triple therapy with the PD-1 antibody, Peg-IFNα, and NAs during Weeks 12-24.
After completion of PD-1 antibody treatment at Week 24, participants will continue Peg-IFNα plus NAs through Week 48.
|
Sintilimab will be administered intravenously at a dose of 1.0 mg/kg at Weeks 0, 6, 12, and 18, for a total of four doses.
Peg-IFNα will be administered subcutaneously once weekly from Week 12 through Week 48. Dose: 135 μg or 180 μg, according to the study protocol. When sintilimab and Peg-IFNα are scheduled during the same treatment period, administration of the two drugs will be separated by at least 72 hours.
Background nucleos(t)ide analogue therapy with entecavir, tenofovir disoproxil fumarate, or tenofovir alafenamide will be continued throughout the study.
