This Registry is designed to provide long term clinical and virologic follow up in participants who have achieved sustained virologic response (SVR) while participating in a previous Gilead sponsored hepatitis C virus (HCV) study. This long term follow up study is observational and no treatment is provided for HCV.
Proportion of participants maintaining SVR at Week 144 by treatment regimen [ Time Frame: Week 144 ]
Secondary Outcome Measures :
Proportion of participants with detectable HCV RNA due to reemergence of preexisting virus through Week 144 by treatment regimen [ Time Frame: Up to 144 weeks ]
Proportion of participants with detectable HCV resistance mutations through Week 144 by treatment regimen [ Time Frame: Up to 144 weeks ]
Proportion of participants with detectable HCV RNA due to reinfection through Week 144 by treatment regimen [ Time Frame: Up to 144 weeks ]
Liver disease progression [ Time Frame: Up to 144 weeks ]
Liver disease progression is a composite endpoint measured by laboratory parameters (alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, albumin, platelets, prothrombin time (PT) and α-fetoprotein) and observed or reported clinical signs and symptoms.
Proportion of participants who develop hepatocellular carcinoma (HCC) through Week 144 by treatment regimen [ Time Frame: Up to 144 weeks ]
