Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Sustained Virologic Response 12 Weeks After Discontinuation of Therapy (SVR12)	SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ) 12 weeks following the last dose of study treatment.	Posttreatment Week 12
Primary	Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event		Up to 12 Weeks
Secondary	Percentage of Participants With Sustained Virologic Response 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24)	SVR4 and SVR24 were defined as HCV RNA < LLOQ at 4 and 24 weeks following the last dose of study treatment, respectively.	Posttreatment Weeks 4 and 24
Secondary	Percentage of Participants With HCV RNA < LLOQ on Treatment		Baseline through end of treatment (Week 6, Week 8 or Week 12, as applicable)
Secondary	HCV RNA Change From Baseline		Baseline through end of treatment (Week 6, Week 8 or Week 12, as applicable)
Secondary	Percentage of Participants With Virologic Failure	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
