This Registry is designed to obtain long term data on participants who have failed to achieve sustained virologic response (SVR) while receiving at least one Gilead oral antiviral agent (OAV) in a previous Gilead-sponsored hepatitis C virus (HCV) study.
||Observational Model: Cohort
Time Perspective: Prospective
||A Long Term Follow-up Registry Study of Subjects Who Did Not Achieve Sustained Virologic Response in Gilead-Sponsored Trials in Subjects With Chronic Hepatitis C Infection
Primary Outcome Measures:
- Proportion of participants with at least one drug resistant mutation (DRM) loss from enrollment to end of study by treatment regimen [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
Biospecimen Retention: Samples Without DNA
Secondary Outcome Measures:
- Proportion of participants with DRM loss by unit category, 1, 2, 3,…n, by treatment regimen [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
- Average number of DRM loss by treatment regimen [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
- Liver disease progression [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]
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 ] [ Designated as safety issue: No ]
