Primary Outcome Measures :
  1. Percentage of Participants With Sustained Virologic Response 12 Weeks After Discontinuation of Therapy (SVR12) [ Time Frame: Posttreatment Week 12 ]
    SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ) 12 weeks following the last dose of study drug.

  2. Percentage of Participants Who Discontinued LDV/SOF Drug Due to an Adverse Event (AE) [ Time Frame: 12 weeks ]

Secondary Outcome Measures :
  1. Percentage of Participants With Sustained Virologic Response 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 4 and 24 weeks after the last dose of study drug, respectively.

  2. Percentage of Participants With Overall Virologic Failure [ Time Frame: Up to Posttreatment Week 24 ]

    Virologic failure was defined as

    • On-treatment virologic failure

      • confirmed HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ, while on treatment (ie, breakthrough),
      • confirmed > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment (ie, rebound),
      • HCV RNA persistently ≥ LLOQ through 8 weeks of treatment (ie, nonresponse)
    • Relapse

      • HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at end of treatment, confirmed with 2 consecutive values or last available posttreatment measurement
