Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 24 Weeks Following Completion of Treatment (SVR24)Post-treatment Week 24

SVR24 was defined as HCV RNA \< the limit of detection (LOD; \< 15 IU/mL) 24 weeks after the last dose of study drug.

Percentage of Participants Who Experienced Adverse EventsBaseline (Day 1) to post-treatment Day 30

Adverse events (AEs) occurring from baseline (Day 1 for all groups) to 30 days following the last dose of study drug were summarized across the participant population. A participant was counted once if they had a qualifying event.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 12 Weeks Following Completion of Treatment (SVR12)Post-treatment Week 12

SVR12 was defined as HCV RNA \< LOD 12 weeks after the last dose of study drug.

Change in HCV RNA at Week 2Baseline (Day 1) to Week 2
Change in HCV RNA at Week 4Baseline (Day 1) to Week 4
Change in HCV RNA at Week 8Baseline (Day 1) to Week 8
Change in HCV RNA at Week 12Baseline (Day 1) to Week 12
Percentage of Participants With HCV RNA < LOD at Week 2Week 2
Percentage of Participants With HCV RNA Below < LOD at Week 4Week 4
Percentage of Participants With HCV RNA Below < LOD at Week 8Week 8
Percentage of Participants With HCV RNA Below < LOD at Week 12Week 12
Percentage of Participants With HCV RNA Below < LOD at Week 24Week 24
Percentage of Participants With ALT Normalization at Week 12Baseline (Day 1) to Week 12

ALT normalization was defined as ALT \> ULN at baseline and ALT ≤ ULN at Week 12.

Percentage of Participants With ALT Normalization at Week 24Baseline (Day 1) to Week 24

ALT normalization was defined as ALT \> ULN at baseline (Day 1 for all groups) and ALT ≤ ULN at Week 24.

Percentage of Participants With ALT Normalization at Post-treatment Week 4Baseline (Day 1) to Post-treatment Week 4

ALT normalization was defined as ALT \> ULN at baseline (Day 1 for all groups) and ALT ≤ ULN at Post-treatment Week 4.

Percentage of Participants With Virologic Failure During TreatmentBaseline (Day 1) to Week 24

Virologic failure was defined as either

* HCV RNA ≥ 15 IU/mL after having previously had HCV RNA \< 15 IU/mL while on treatment, confirmed with 2 consecutive values or last available measurement (ie, breakthrough);

* \> 1 log10 IU/mL increase in HCV RNA from nadir while on treatment, confirmed with 2 consecutive values or last available measurement (ie, rebound);or

* HCV RNA persistently ≥ 15 IU/mL through 8 weeks of treatment (ie, nonresponse)

Baseline was Day 1 for all groups.

Percentage of Participants With Virologic Failure Following Treatment (Viral Relapse).End of treatment to Post-treatment Week 24

Viral relapse was defined as HCV RNA \< 15 IU/mL at end of treatment, confirmed with 2 consecutive values or last available measurement.
