HCV NS5B polymerase plays an essential role in HCV replication. Sofosbuvir (Sovaldi) is a NS5B polymerase inhibitor that results in suppression of HCV replication and life cycle. Sofosbuvir received FDA approval in December 2013 for treatment of chronic HCV infection with genotypes 1, 2, 3, and 4 as part of a combination antiviral regimen, including those with hepatocellular carcinoma (HCC) meeting Milan criteria (awaiting liver transplantation) to prevent HCV recurrence and those with HCV/HIV-1 coinfection.
