Mechanism of action

Odalasvir is a direct-acting antiviral (DAA) that targets the NS5A protein of hepatitis C virus. NS5A is a multifunctional, zinc-binding phosphoprotein that plays critical roles in HCV RNA replication, virion assembly, and host cell interactions. By binding to and inhibiting NS5A, odalasvir disrupts the viral replication complex, preventing the virus from making copies of itself and assembling infectious particles. This mechanism is distinct from protease inhibitors (which block viral protein processing) and polymerase inhibitors (which block RNA synthesis), allowing odalasvir to be combined with drugs targeting other viral proteins for enhanced antiviral activity. The drug was developed as part of a multi-DAA combination strategy to achieve high cure rates in hepatitis C patients across different viral genotypes.
