Sequential PD-1 Antibody and Pegylated Interferon Therapy for Nucleos(t)Ide Analogue-suppressed Chronic Hepatitis B

2. september 2026 oppdatert av: Beijing 302 Hospital

Safety and Efficacy of Sequential Treatment With a PD-1 Antibody and Pegylated Interferon-α in Nucleos(t)Ide Analogue-Suppressed Patients With Chronic Hepatitis B

This is a prospective, multicenter, randomized, open-label controlled clinical trial designed to evaluate the efficacy and safety of a sequential treatment strategy incorporating a PD-1 antibody and pegylated interferon-α (Peg-IFNα) in patients with chronic hepatitis B receiving stable nucleos(t)ide analogue (NA) therapy.

Detaljert beskrivelse

A total of 60 participants will be randomly assigned in a 1:1 ratio to an experimental group or a control group. Participants in the experimental group will initially receive a PD-1 antibody in combination with continued NA therapy, followed by a period of triple therapy with the PD-1 antibody, Peg-IFNα, and NAs. The PD-1 antibody will then be discontinued, while Peg-IFNα plus NAs will be continued through Week 48. Participants in the control group will receive Peg-IFNα plus continued NA therapy from baseline through Week 48.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Eksperimentell: 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.
Legemiddel: Sintilimab
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.
Legemiddel: Pegylated Interferon-α 2b

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.

Legemiddel: Nucleos(t)ide Analogues
Background nucleos(t)ide analogue therapy with entecavir, tenofovir disoproxil fumarate, or tenofovir alafenamide will be continued throughout the study.

  • ETV
  • TAF
