• First Posted Date: October 24, 2011
• Last Update Posted Date: May 4, 2018
• Actual Study Start Date: December 19, 2011
• Actual Primary Completion Date: April 9, 2018 (Final data collection date for primary outcome measure)
• Current Primary Outcome Measures (submitted: December 8, 2014): 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 ]

Original Primary Outcome Measures (submitted: October 20, 2011)

Viral Activity [ Time Frame: 3 years ]

To characterize HCV viral sequences and the persistence or evolution of treatment emergent viral mutations in subjects who fail to achieve an SVR after treatment with a Gilead oral antiviral (OAV) containing regimen in a previous Gilead-sponsored hepatitis C study

Current Secondary Outcome Measures (submitted: December 8, 2014)

• 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 ]

Original Secondary Outcome Measures (submitted: October 20, 2011)

• Clinical progression of liver disease [ Time Frame: 3 years ]
  Clinical progression of liver disease will be assessed by review of clinical signs, symptoms and laboratory parameters (clinical chemistry, haematology, coagulation and alfa-feto protein).
• Development of hepatocellular carcinoma (HCC) [ Time Frame: 3 years ]
  Screening for the development of HCC will comprise of review of clinical signs and symptoms and laboratory parameters including alfa-feto protein.
