Sofosbuvir is used for the treatment of chronic hepatitis C, genotypes 1, 2, 3, and 4, in combination with pegylated interferon and ribavirin, or with ribavirin alone. It is also used in combination with the viral NS5a inhibitor ledipasvir in an interferon-free combination for the treatment of genotype 1 hepatitis C infection. sofosbuvir also used along with the daclatasvir for the genotype 3 indication and also available pangenotypic combination of sofosbuvir and velpatasvir. Sofosbuvir is also used in HCV patients with an HIV coinfection. The treatment is based on a number of clinical trials, for example the ELECTRON trial which showed that a dual interferon-free regimen of sofosbuvir plus ribavirin produced a 24-week post-treatment sustained virological response (SVR24) rate of 100% for previously untreated patients with HCV genotypes 2 or 3.
