Hepatitis C virus (HCV) NS5B RNA-dependent RNA polymerase (RdRp) plays a central role in virus replication. NS5B has no functional equivalent in mammalian cells, and as a consequence is an attractive target for selective inhibition. This paper describes the discovery of a novel family of HCV NS5B non-nucleoside inhibitors inspired by the bioisosterism between sulfonamide and phosphonamide. Systematic structural optimization in this new series led to the identification of IDX375, a potent non-nucleoside inhibitor that is selective for genotypes 1a and 1b. The structure and binding domain of IDX375 were confirmed by X-ray co-crystalisation study.

ABSTRACT:

IDX375 is a potent and selective palm-binding nonnucleoside inhibitor of the hepatitis C virus (HCV) genotype 1 polymerase. This first-in-human study evaluated the safety, tolerability, and pharmacokinetics of IDX375 in healthy volunteers, as well as its antiviral activity in HCV-infected patients. IDX375, as a choline salt, was administered for 1 day to 40 healthy male volunteers (25- to 200-mg IDX375-equivalent single ascending doses and a 200-mg twice-daily [BID] dose) and three patients chronically infected with HCV genotype 1 (200 mg BID only). IDX375 was well absorbed and well tolerated by all of the study participants. A single-day 200-mg BID dose resulted in exposure-related anti-HCV activity with maximal 0.5 to 1.1 log 10 reductions in plasma HCV RNA. These observations support further clinical investigations of IDX375.
