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

Summary

This study tested a new combination of two antiviral pills, bemnifosbuvir and ruzasvir, taken once daily for 8 weeks in 275 adults with chronic hepatitis C. The main goal was to see if the virus was still undetectable 12 weeks after treatment ended. The trial is now complete, and results will show how safe and effective this short treatment course is.
