Journal ArticleDOI

An NS3 protease inhibitor with antiviral effects in humans infected with hepatitis C virus.

TL;DR: Administration of BILN 2061 to patients infected with HCV genotype 1 for 2 days resulted in an impressive reduction of HCV RNA plasma levels, and established proof-of-concept in humans for an HCV NS3 protease inhibitor, illustrating the potential of the viral-enzyme-targeted drug discovery approach for the development of new HCV therapeutics.
Journal ArticleDOI

Generating an In Vitro–In Vivo Correlation for Metabolism and Liver Enrichment of a Hepatitis C Virus Drug, Faldaprevir, Using a Rat Hepatocyte Model (HepatoPac)

TL;DR: The studies suggest that HepatoPac is a promising in vitro model to predict in vivo liver enrichment and metabolism, especially for glucuronidation, and has demonstrated superiority over suspended hepatocytes.
Journal ArticleDOI

Mass Balance and Metabolite Profiling of Steady-State Faldaprevir, a Hepatitis C Virus NS3/4 Protease Inhibitor, in Healthy Male Subjects

TL;DR: Faldaprevir is predominantly excreted in feces with negligible urinary excretion, and the terminal half-life of radioactivity in plasma was approximately 23 h with no evidence of any long-lasting metabolites.
Journal ArticleDOI

Biotransformation and mass balance of faldaprevir, a hepatitis C NS3/NS4 protease inhibitor in rats.

TL;DR: Radioactivity was rapidly distributed into tissues after the oral dose with peak concentrations of radioactivity in most tissues at 6 h post-dose, and the highest levels ofRadioactivity were observed in liver, lung, kidney, small intestine and adrenal gland.
