Mechanism of action

TMC435 is a direct-acting antiviral that selectively binds to and inhibits the NS3/4A serine protease of hepatitis C virus. This protease is essential for cleaving the HCV polyprotein into functional viral proteins. By blocking this enzyme, TMC435 prevents viral replication and reduces viral load in infected patients.
