Could a cancer drug help cure hepatitis b? new trial launches

NCT ID NCT06357806

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This pilot study tests whether adding a PD-1 antibody (sintilimab) and pegylated interferon to standard antiviral therapy can help people with chronic hepatitis B lose the hepatitis B surface antigen (HBsAg), a key step toward a functional cure. The trial will enroll 45 adults who have been on antivirals for at least a year and have low but detectable HBsAg levels. Researchers will monitor safety and how many participants clear HBsAg at 24 and 48 weeks.

What this could mean

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

Active substance
Sintilimab (PD-1 antibody) combined with pegylated interferon-α2b
What this could lead to
If successful, this combination could help more people with chronic hepatitis B achieve a functional cure, meaning the virus is suppressed without lifelong medication.
What could go wrong
This is a small, early pilot study with only 45 participants, so results may not apply broadly. The treatment can cause immune-related side effects, and it is not yet known if it will work better than standard care.
