Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Subjects With Undetectable Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) at Week 24 After the Completion of Study Drug Dosing	The plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay. The lower limit of detection was 10 international units per milliliter (IU/mL).	24 weeks after the completion of study drug dosing (up to Week 72)	No
Secondary	Percentage of Subjects With Undetectable Plasma HCV RNA at Week 12 After the Completion of Study Drug Dosing	The plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay. The lower limit of detection was 10 international units per milliliter (IU/mL).	12 weeks after the completion of study drug dosing (up to Week 60)	No
Secondary	Percentage of Subjects With Undetectable Plasma HCV RNA at Completion of Study Drug Dosing	The plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay. The lower limit of detection was 10 international units per milliliter (IU/mL).	Completion of study drug dosing (up to Week 48)	No
Secondary	Number of Subjects With Adverse Events (AEs) and Serious Adverse Events (SAEs)	AE: any adverse change from the subject's baseline (pre-treatment) condition, including any adverse experience, abnormal recording or clinical laboratory assessment value which occurs during the course of the study, whether it is considered related to the study drug or not. An adverse event includes any newly occurring event or previous condition that has increased in severity or frequency since the administration of study drug. SAE: medical event or condition, which falls into any of the following categories, regardless of its relationship to the study drug: death, life threatening adverse experience, in-patient hospitalization/prolongation of hospitalization, persistent/significant disability or incapacity, congenital anomaly/birth defect, important medical event. "Study drug" includes all investigational agents (including placebo, if applicable) administered during the course of the study.	Baseline up to Week 48	Yes
Secondary	Number of Subjects With Viral Relapse	Viral relapse was defined as having detectable HCV RNA during antiviral follow-up. The plasma HCV RNA level was measured using Roche TaqMan HCV RNA assay. The lower limit of detection was 10 international units per milliliter (IU/mL).	After last dose of study drug up to antiviral follow-up (up to Week 72)	No
Secondary	Maximum (Cmax), Minimum (Cmin) and Average (Cavg) Plasma Concentration of Telaprevir	Only subjects who received telaprevir were to be analyzed for this outcome. Maximum, minimum and average plasma concentrations observed during assessment period were reported.	Day 1, 4, 8, 15, 22, 29, 43, 57, 71, 85	No
