New combo aims to cure hepatitis b in over half of patients

NCT ID NCT05771402

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This phase 2 trial tests a combination of an anti-PD-1 antibody, interferon, and standard antiviral drugs in 120 adults with chronic hepatitis B. The goal is to boost the immune system to clear the virus and achieve a functional cure, where the virus stays under control without lifelong treatment. The study builds on earlier work that achieved cure in up to 50% of certain patients, and aims to improve that rate further.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Anti-PD-1 antibody, Peg-IFNα, and nucleos(t)ide analogues (ETV/TDF/TAF)

What this could lead to

If successful, this combination could help more than half of patients with chronic hepatitis B achieve a functional cure, meaning the virus is controlled without lifelong medication.

What could go wrong

This is a phase 2 trial with only 120 participants, so results are preliminary. The anti-PD-1 antibody may cause immune-related side effects, and the cure rate may not reach the hoped-for 50%.
