Primary Outcome Measures :
  1. 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, 15 IU/mL) at 12 weeks after stopping study treatment.

  2. Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event [ Time Frame: Up to 12 weeks ]

Secondary Outcome Measures :
  1. 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 SVR 24 were defined as HCV RNA < LLOQ at 4 and 24 weeks after stopping study treatment, respectively.

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

    Virologic failure was defined as:

    • On-treatment virologic failure:

      • 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:

      • Confirmed HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at last on-treatment visit.
