  Purpose

This study will evaluate the antiviral efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) administered for 12 weeks in hepatitis C virus (HCV) treatment-naive and treatment-experienced (including treatment intolerant) participants with chronic genotype 1 or 4 HCV infection who are co-infected with HIV-1.

Participants who experience confirmed post-treatment virologic failure (relapse) at or before Posttreatment Week 24 may be eligible to be enrolled in the Retreatment Substudy to receive LDV/SOF plus ribavirin (RBV) for 24 weeks.

Primary Outcome Measures:
  • Percentage of Participants With Sustained Virologic Response (SVR) 12 Weeks After Discontinuation of Therapy (SVR12) [ Time Frame: Posttreatment Week 12 ] [ Designated as safety issue: No ]
    SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 25 IU/mL) at 12 weeks after stopping study treatment.

  • Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event [ Time Frame: Up to 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Percentage of Participants With SVR at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24) [ Time Frame: Posttreatment Weeks 4 and 24 ] [ Designated as safety issue: No ]
    SVR4 and SVR 24 were defined as HCV RNA < LLOQ at 4 and 24 weeks after stopping study treatment, respectively.

  • Percentage of Participants With HCV RNA < LLOQ at Weeks 1, 2, 4, 6, 8, 10, and 12 [ Time Frame: Weeks 1, 2, 4, 6, 8, 10, and 12 ] [ Designated as safety issue: No ]
  • Change From Baseline in HCV RNA at Weeks 1, 2, 4, 6, and 8 [ Time Frame: Baseline; Weeks 1, 2, 4, 6, and 8 ] [ Designated as safety issue: No ]
  • Percentage of Participants With Virologic Failure [ Time Frame: Up to Posttreatment Week 24 ] [ Designated as safety issue: No ]

    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.

  • Percentage of Participants That Maintain HIV-1 RNA < 50 Copies/mL While on HCV Treatment [ Time Frame: Weeks 4, 8, and 12 ] [ Designated as safety issue: No ]
  • Change From Baseline in Serum Creatinine at the End of Treatment (Week 12) and at Posttreatment Weeks 12 and 24 [ Time Frame: Baseline; Week 12, Posttreatment Weeks 12 and 24 ] [ Designated as safety issue: No ]
  • For Participants in the Retreatment Substudy, Percentage of Participants With SVR at 4, 12, and 24 Weeks After Discontinuation of Therapy (SVR4, SVR12, and SVR24) [ Time Frame: Posttreatment Weeks 4, 12, and 24 of Retreatment Substudy ] [ Designated as safety issue: No ]
    SVR4, SVR12, and SVR 24 were defined as HCV RNA < LLOQ at 4, 12, and 24 weeks after stopping study treatment, respectively.

  • For Participants in the Retreatment Substudy, Percentage of Participants With HCV RNA < LLOQ at Retreatment Weeks 2, 4, 8, 12, 16, 20, and 24 [ Time Frame: Weeks 2, 4, 8, 12, 16, 20, and 24 of the Retreatment Substudy ] [ Designated as safety issue: No ]
  • For Participants in the Retreatment Substudy, Change From Baseline in HCV RNA at Retreatment Weeks 2, 4, and 8 [ Time Frame: Baseline; Weeks 2, 4, and 8 of Retreatment Substudy ] [ Designated as safety issue: No ]
  • For Participants in the Retreatment Substudy, Percentage of Participants With Virologic Failure [ Time Frame: Up to Posttreatment Week 24 of Retreatment Substudy ] [ Designated as safety issue: No ]

    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.
