What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event
Time Frame: Up to 12 weeks
Up to 12 weeks
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.
Posttreatment Week 12

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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 at 4 and 24 weeks following the last dose of study drug, respectively.
Posttreatment Weeks 4 and 24
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
Up to Posttreatment Week 24
Percentage of Participants With HCV RNA < LLOQ on Treatment
Time Frame: Up to 12 Weeks
Up to 12 Weeks
HCV RNA Change From Baseline/Day 1
Time Frame: Baseline to Week 12
Baseline to Week 12
Percentage of Participants That Maintained HIV-1 RNA < 50 Copies/mL While On HCV Treatment
Time Frame: Up to 12 Weeks
Up to 12 Weeks
Serum Creatinine Change From Baseline At the End of Treatment and At Posttreatment Week 12
Time Frame: Week 12; Posttreatment Week 12
Week 12; Posttreatment Week 12
