Mechanism of action

Sofosbuvir is a nucleotide analog that inhibits the NS5B RNA-dependent RNA polymerase. Velpatasvir inhibits the NS5A protein, which is essential for viral replication and assembly. Voxilaprevir inhibits the NS3/4A serine protease. Together, these three agents target different steps of the HCV lifecycle, providing a pangenotypic, direct-acting antiviral regimen with high barrier to resistance.
