Experimental hepatitis b drug trial halted midway

NCT ID NCT02604212

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

Summary

This study tested an experimental drug called ARC-520 in 32 adults with chronic hepatitis B who were already taking antiviral medications (entecavir or tenofovir). The goal was to see if adding ARC-520 could lower hepatitis B surface antigen levels more than placebo. The trial was terminated early, so results are limited.
