SponsorMyeong Jun Song
Drug classDirect-acting antiviral combination (NS5A inhibitor + NS3/4A protease inhibitor)
TargetHCV NS5A protein and HCV NS3/4A serine protease
ModalitySmall molecule
Therapeutic areaInfectious Disease (Hepatology)
PhaseFDA-approved

Mechanism of action

Daclatasvir is an NS5A inhibitor that disrupts hepatitis C virus replication and assembly, while asunaprevir is an NS3/4A protease inhibitor that prevents cleavage of viral polyproteins necessary for viral maturation. Together, this combination targets two distinct steps in the HCV life cycle, reducing the likelihood of resistance development.
