Deleobuvir sodium is the salt form of Deleobuvir, also known as BI207127, a non-nucleoside hepatitis C virus NS5B polymerase inhibitor for the treatment of hepatitis C. Deleobuvir was tested in combination regimens with pegylated interferon and ribavirin, and in interferon-free regimens with other direct-acting antiviral agents including faldaprevir. Deleobuvir showed that a triple combination of deleobuvir, faldaprevir, and ribavirin performed well in HCV genotype 1b patients.
