Outcomes
Primary Outcomes
Incidence of Adverse Events Leading to Permanent Discontinuation of Study Drug(s)
Time Frame: Up to 24 weeks
The percentage of participants discontinuing any study drug due to an adverse event was summarized.
Percentage of Participants With Sustained Virologic Response (SVR) at 12 Weeks After Discontinuation of Therapy (SVR12)
Time Frame: Posttreatment Week 12
SVR12 was defined as HCV RNA \< the lower limit of quantitation (LLOQ; ie, 25 IU/mL) at 12 weeks after stopping study treatment.
Secondary Outcomes
- Percentage of Participants Experiencing On-treatment Virologic Failure(Up to 24 weeks)
- Percentage of Participants Experiencing Viral Relapse(Up to Posttreatment Week 24)
- Percentage of Participants With Sustained Virologic Response at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24)(Posttreatment Weeks 4 and 24)
