  • Percentage of Participants With Sustained Virologic Response (SVR) 12 Weeks After Discontinuation of Therapy (SVR12) [ Time Frame: Posttreatment Week 12 ]
    SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 25 IU/mL) 12 weeks following the last dose of study drug.
  • Incidence of Adverse Events Leading to Permanent Discontinuation From Any Study Drug [ Time Frame: Up to 24 weeks ]
    The percentage of participants who experienced an adverse event leading to permanent discontinuation from any study drug was summarized.
  • Sustained virologic response after discontinuation of therapy [ Time Frame: 12 weeks after discontinuation of therapy ]
    Sustained virologic response (SVR) 12 weeks after the end of treatment (SVR12 defined as HCV RNA < lower limit of quantification [LLOQ] 12 weeks after last dose of study drug).
  • Safety and tolerability of combination treatment with sofosbuvir (SOF)/GS-5885 fixed-dose combination (FDC) ± RBV as measured by review of the accumulated safety data [ Time Frame: Safety and tolerability on treatment and 30 days post last dose ]

  • Percentage of Participants With SVR at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24) [ Time Frame: Posttreatment Weeks 4 and 24 ]
    SVR4 and SVR24 were defined as HCV RNA < LLOQ at 4 and 24 weeks following the last dose of study drug, respectively.
  • Percentage of Participants With HCV RNA < LLOQ at Week 1 [ Time Frame: Week 1 ]
  • Percentage of Participants With HCV RNA < LLOQ at Week 2 [ Time Frame: Week 2 ]
  • Percentage of Participants With HCV RNA < LLOQ at Week 4 [ Time Frame: Week 4 ]
  • Percentage of Participants With HCV RNA < LLOQ at Week 8 [ Time Frame: Week 8 ]
  • Percentage of Participants With HCV RNA < LLOQ at Week 12 [ Time Frame: Week 12 ]
  • Percentage of Participants With HCV RNA < LLOQ at Week 24 [ Time Frame: Week 24 ]
  • Change From Baseline in HCV RNA at Week 1 [ Time Frame: Baseline; Week 1 ]
  • Change From Baseline in HCV RNA at Week 2 [ Time Frame: Baseline; Week 2 ]
  • Change From Baseline in HCV RNA at Week 4 [ Time Frame: Baseline; Week 4 ]
  • Change From Baseline in HCV RNA at Week 8 [ Time Frame: Baseline; Week 8 ]
  • Percentage of Participants With Virologic Failure [ Time Frame: Baseline to posttreatment Week 24 ]

    Virologic failure was defined as on-treatment virologic failure or virologic relapse.

    • On-Treatment Virologic Failure was defined as

      • Breakthrough (confirmed HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ while on treatment), or
      • Rebound (confirmed > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment), or
      • Non-response (HCV RNA persistently ≥ LLOQ through 8 weeks of treatment)

    Virologic relapse was defined as confirmed HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at last on-treatment visit.

  • Sustained virologic response after discontinuation of therapy [ Time Frame: 4 and 24 weeks after discontinuation of therapy ]
    Sustained virologic response (SVR) at 4 and 24 weeks after discontinuation of therapy (SVR4 and SVR24 defined as HCV RNA < lower limit of quantification [LLOQ] 12 weeks after last dose of study drug).
  • Kinetics of circulating HCV RNA during and after treatment discontinuation [ Time Frame: 12 and 24 weeks ]
    On treatment and post treatment HCV RNA levels over time will be used to characterize the kinetics of circulating HCV RNA during and after treatment discontinuation.
  • Viral resistance to sofosbuvir and GS-5885 combination therapy during and after treatment [ Time Frame: 12 and 24 weeks ]
    To evaluate the emergence of viral resistance to sofosbuvir and GS-5885 during treatment and after treatment discontinuation
  • Characterization of steady state pharmacokinetics of sofosbuvir and GS-5885 [ Time Frame: 12 and 24 weeks ]
    To characterize steady state pharmacokinetics of sofosbuvir and GS-5885 during treatment and after treatment discontinuation
