Overview
Brief Summary
The purpose of this study was to determine the safety, tolerability, pharmacokinetics and anti-viral activity of JTK-853 in hepatitis C virus genotype 1 infected subjects based on reduction in viral load (HCV RNA level) from baseline to end of treatment, followed by genotypic resistance monitoring for up to one year after study drug treatment.
