Condition
Hepatitis C, Chronic

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 ]

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 ]
  • Average number of DRM loss by treatment regimen [ Time Frame: Up to 3 years ]
  • Liver disease progression [ Time Frame: Up to 3 years ]
    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 ]

Biospecimen Retention:   Samples Without DNA
