Information
Lomibuvir (VX-222) Lomibuvir (VX-222, VCH-222) is a novel, potent and selective inhibitor of HCV polymerase with IC50 of 0.94-1.2 μM, 15.3-fold less effective for mutant M423T, and 108-fold less effective for mutant I482L. Phase 2.
In vitro
VX-222 binds to the thumb II allosteric pocket of the HCV RNA-dependent RNA polymerase. VX-222 exhibits non-competitive and selective inhibition in HCV NS5B of genotype 1a and 1b, with IC50 of 0.94 and 1.2 μM, respectively. VX-222 selectively inhibits the replication of subgenomic HCV genotype 1a and 1b with an EC50 of 22.3 and 11.2 nM, respectively. Similarly, a recent study shows that VX-222 inhibits the 1b/Con1 HCV subgenomic replicon, with an EC50 of 5 nM. VX-222 preferentially inhibits primer-dependent RNA synthesis, showing only a modest or no effect on de novo-initiated RNA synthesis.
In vivo
In rats and dogs, VCH-222 displays fine pharmacokinetic profile, including low total body clearance and excellent oral bioavailability (greater than 30%) and good ADME properties. VCH-222 is biotransformed by several enzymes (CYP1A1, 2A6, 2B6, 2C8, CYP 3A4, UGT1A3) and is predicted to be actively transported in liver and excreted mainly intact in bile or as glucuronide adducts.
