- Percentage of Participants With Sustained Virologic Response (SVR) 12 Weeks After Discontinuation of Therapy (SVR12) [ Time Frame: Posttreatment Week 12 ]SVR12 was defined as hepatitis C virus ribonucleic acid (HCV RNA) < the lower limit of quantitation (LLOQ; ie, 15 IU/mL) at 12 weeks after stopping study treatment. The exact 95% confidence interval (CI) for the percentage within treatment group was based on the Clopper-Pearson method.
- Percentage of Participants Who Permanently Discontinued Study Drug Due to an Adverse Event [ Time Frame: First dose date up to Week 24 ]
- Percentage of Participants With SVR at 4 Weeks After Discontinuation of Therapy (SVR4) [ Time Frame: Posttreatment Week 4 ]SVR4 was defined as HCV RNA < LLOQ (ie, 15 IU/mL) at 4 weeks after stopping study treatment. The exact 95% CI for the percentage within treatment group was based on the Clopper-Pearson method.
- Percentage of Participants With SVR at 24 Weeks After Discontinuation of Therapy (SVR24) [ Time Frame: Posttreatment Week 24 ]SVR24 was defined as HCV RNA < LLOQ (ie, 15 IU/mL) at 24 weeks after stopping study treatment. The exact 95% CI for the percentage within treatment group was based on the Clopper-Pearson method.
- Percentage of Participants With HCV RNA < LLOQ on Treatment [ Time Frame: Weeks 2, 4, 6, 8, 12, 16, 20, 24 ]The total number of participants with HCV RNA < LLOQ was the sum of the number of participants with HCV RNA "< LLOQ detected" plus the number of participants with HCV RNA "< LLOQ target not detected (TND)". LLOQ was 15 IU/mL. The exact 95% CI for the percentage within treatment group was based on the Clopper-Pearson method.
- HCV RNA [ Time Frame: Weeks 2, 4, 6, 8, 12, 16, 20, 24 ]
- Change From Baseline in HCV RNA [ Time Frame: Weeks 2, 4, 6, 8, 12, 16, 20, 24 ]
- Percentage of Participants With Virologic Failure [ Time Frame: Baseline 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.

- Percentage of Participants Who Developed Resistance to LDV and SOF [ Time Frame: Baseline up to Posttreatment Week 24 ]
- Pharmacokinetics (PK) Parameter: AUCtau of LDV [ Time Frame: Sparse PK Samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Weeks 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=2)) ]AUCtau is defined as the population PK derived area under the concentration versus time curve of the drug over the dosing interval.
- PK Parameter: AUCtau of SOF [ Time Frame: Sparse PK Samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Weeks 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=2)) ]AUCtau is defined as the population PK derived area under the concentration versus time curve of the drug over the dosing interval.
- PK Parameter: AUCtau of GS-331007 (Metabolite of SOF) [ Time Frame: Sparse PK Samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Weeks 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=2)) ]AUCtau is defined as the population PK derived area under the concentration versus time curve of the drug over the dosing interval.
- PK Parameter: Cmax of LDV [ Time Frame: Sparse PK Samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Weeks 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=2)) ]Cmax is defined as the population PK derived maximum concentration of the drug.
- PK Parameter: Cmax of SOF [ Time Frame: Sparse PK Samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Weeks 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=2)) ]Cmax is defined as the population PK derived maximum concentration of the drug.
- PK Parameter: Cmax of GS-331007 (Metabolite of SOF) [ Time Frame: Sparse PK Samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Weeks 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=2)) ]Cmax is defined as the population PK derived maximum concentration of the drug.
