Around 3% of the human population is infected with hepatitis C virus (HCV) and 70-80% of these individuals develop a chronic infection. There is no vaccine available against HCV and up to 50% of the infected patients do not respond to standard therapy, based on the combination of interferon-alpha (IFN-α) and ribavirin. Recently, direct acting antiviral drugs against HCV have been made available for treatment, leading to a significant improvement in therapeutic success. In 2014, the U.S. Food and Drug Administration approved ledipasvir plus sofosbuvir to treat the chronic infection, the first IFN- and ribavirin-free approved treatment. With such treatment, the eradication of the disease would be feasible, although drug costs are high. Host target therapy represents an emerging alternative, based on the understanding of host factors involved in the HCV infection. This therapy might show at least two theoretical benefits, increasing the number of options for therapy and raising the genetic barrier for selection of resistant variants. New treatment regimens may consist of classical therapy combined with host target-based therapy, hopefully in a synergistic manner.
