Study Endpoints

Primary Endpoints

Number of Subjects Achieving Sustained Viral Response (SVR), Demonstrated by Achieving Undetectable Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Levels 24 Weeks After Last Planned Dose of Study Treatment
24 weeks after last planned dose of study treatment (up to Week 72)

The plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay. The lower limit of quantification was 25 international units per milliliter (IU/mL) and the lower limit of detection was 10 IU/mL. Two results are reported: 1) Protocol defined SVR: undetectable HCV RNA at 24 weeks after the last planned dose of study treatment without any confirmed detectable HCV RNA between end of treatment visit (up to Week 48) and 24 weeks after last planned dose (up to Week 72); 2) SVR as per FDA guidance (snapshot analysis): undetectable HCV RNA at 24 weeks after the last planned dose of study treatment. Analysis was based only on the HCV RNA assessment in visit window (+/-2 weeks); if there were more than 1 assessment in the window, the last measurement was used.

Secondary Endpoints
