NCT ID NCT04856085

First seen Nov 01, 2025 · Last updated May 13, 2026 · Updated 28 times

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 clear the hepatitis B virus from the blood. 244 adults with chronic hepatitis B who were already on antiviral therapy took part. The main goals were to check for side effects and see if the virus's surface antigen (HBsAg) became undetectable, which is a key step toward controlling the infection.
