Brief summary

All subjects in this study have previously been in an Idenix HCV study and received study drug for 3 consecutive days. Subjects who had received placebo in a previous Idenix study will not be enrolled in this study. In this study, researchers will try to find answers to these questions: * How much (if any) hepatitis C virus is in your blood after stopping your Idenix study drug? * Is your hepatitis C virus possibly resistant to treatment with the Idenix study drug or similar drugs?

Detailed description

The data obtained from this study will be used to further understand the long-term efficacy of Idenix DAAs used to treat HCV infection and to further understand HCV resistance to Idenix DAAs.

Design outcomes

Primary

MeasureTime frameDescription
Durability of Sustained viral response [SVR]every 3 monthsTo evaluate the durability of sustained virological response (SVR). Plasma HCV RNA levels will be monitored over time.

Secondary

MeasureTime frameDescription
Kinetics of resistant variantsevery 3 monthsTo describe the kinetics of resistant variants to Idenix direct acting antivirals (DAAs) by HCV RNA sequencing. The presence of each identified resistant variant in the viral population will be descriptively evaluated until the viral population consists entirely of wild-type virus or over a period of 3 years, whichever comes first.
