New hope for hepatitis b: experimental combo aims to clear the virus

NCT ID NCT04856085

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested whether combining two experimental drugs (VIR-2218 and VIR-3434) with or without a standard immune booster (PEG-IFNα) can safely eliminate hepatitis B surface antigen in people with chronic hepatitis B. 244 adults with long-term infection who were already on antiviral therapy took part. The goal was to see if these combinations could achieve undetectable virus levels and possibly allow patients to stop lifelong medication.
