Primary Outcome Measures:

The proportion of subjects who have a sustained viral response at 12 weeks after the last planned dose of treatment [ Time Frame: 12 weeks after the last planned dose of treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

The safety and tolerability as assessed by adverse events (AEs), vital signs, 12-lead electrocardiograms (ECGs), and laboratory assessments (serum chemistry, hematology, and urinalysis) [ Time Frame: up to 20 weeks ] [ Designated as safety issue: Yes ]
The proportion of subjects who have an SVR 24 weeks after the last planned dose of the study drug [ Time Frame: 24 weeks after the last planned dose of the study drug ] [ Designated as safety issue: No ]
The proportion of subjects who have an SVR 4 weeks after the last planned dose of the study drug [ Time Frame: 4 weeks after the last planned dose of the study drug ] [ Designated as safety issue: No ]
The proportion of subjects who relapse (i.e., who had <LLOQ HCV RNA at the end of planned study drug treatment (planned EOT) followed by ≥LLOQ HCV RNA after planned EOT) [ Time Frame: 48 weeks either after the last planned dose of study drug or after time of failure ] [ Designated as safety issue: No ]
The proportion of subjects who achieve undetectable HCV RNA (below the lower limit of detection (<LLOQ undetectable) at Weeks 2, 4, 8, 12, and 16 after the first dose of study drug, and <LLOQ at the end of planned study drug treatment (planned EOT) [ Time Frame: up to 16 weeks ] [ Designated as safety issue: No ]
Time to achieve <LLOQ undetectable HCV RNA [ Time Frame: up to 16 weeks ] [ Designated as safety issue: No ]
The proportion of subjects who have on-treatment virologic failure defined as subjects who either have viral breakthrough or who complete the assigned treatment and have ≥LLOQ HCV RNA at the end of study drug treatment (EOT) [ Time Frame: up to 16 weeks ] [ Designated as safety issue: No ]
The association of the IL-28B genotype (CC versus CT versus TT) with SVR12 [ Time Frame: 12 weeks after the last planned dose of treatment ] [ Designated as safety issue: No ]
The amino acid sequence of the nonstructural (NS)3/4A and NS5B proteins in subjects who have treatment failure [ Time Frame: 48 weeks either after the last planned dose of study drug or after time of failure ] [ Designated as safety issue: No ]
