Hepatitis b drug trial halted midway

NCT ID NCT02577029

First seen Jan 18, 2026 · Last updated May 14, 2026 · Updated 25 times

Summary

This study tested an experimental drug called ARC-520 in 79 adults with chronic hepatitis B. Some participants received ARC-520 alone, while others got it with standard treatments like entecavir or tenofovir. The goal was to see if ARC-520 could lower hepatitis B surface antigen levels. The trial was terminated early, so results are limited.
