Lomibuvir, also known as VX-222, VCH-222 and VX22, is an nonnucleoside NS5B polymerase inhibitor. VX-222 inhibits the 1b/Con1 HCV subgenomic replicon, with 50% effective concentrations (EC(50)s) 5 nM. VX-222 binds to the HCV polymerase with dissociation constants of 17 nM. In phase 1 and 2 clinical studies, VX-222 demonstrated effective antiviral efficacy, with substantial reductions in plasma HCV RNA in patients chronically infected with genotype 1 HCV.
