LDV/SOFLDV/SOFLDV/SOF FDC for 6 weeks
Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 12 Weeks After Completion of Treatment (SVR12)Posttreatment Week 12

SVR12 was defined as HCV RNA \< the lower limit of quantitation (LLOQ) 12 weeks following the last dose of study drug.

Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse EventUp to 6 weeks
Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 4 Weeks After Discontinuation of Study Treatment (SVR4)Posttreatment Week 4

SVR4 was defined as HCV RNA \< LLOQ 4 weeks after the last dose of study drug.

Percentage of Participants With HCV RNA < LLOQ on TreatmentWeeks 2, 4, and 6
Change From Baseline in HCV RNA at Weeks 2, 4, and 6Baseline; Weeks 2, 4, and 6
Percentage of Participants With Virologic FailureUp to Posttreatment Week 12

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 end 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

Change in HIV RNA From Day 1 to End of Treatment as Assessed by Proportion of Participants Who Had Confirmed HIV Virologic Rebound During the Study.Day 1; Week 6

Participants with HIV virologic rebound was defined as participants with at least two HIV RNA ≥ 400 copies/mL at 2 consecutive post-baseline visits which are at least 2 weeks apart based on actual dates.

Percentage of Participants That Maintain HIV-1 RNA < 50 Copies/mL While on HCV Treatment and at Posttreatment Week 4Weeks 2, 4, 6, and Posttreatment Week 4
Percent Change From Baseline in CD4 T-cell Count at the End of Treatment and at Posttreatment Week 4Baseline; Week 6; Posttreatment Week 4
