Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 12 Weeks After Treatment12 weeks after the last actual dose of active study drug

The percentage of participants with sustained virologic response (plasma Hepatitis C virus ribonucleic acid \[HCV RNA\] level less than the lower limit of quantitation \[\< LLOQ\]) 12 weeks after the last dose of study drug.

Secondary Outcome Measures
NameTimeMethod
Percentage of HCV Genotype 1b-infected Participants With Sustained Virologic Response 12 Weeks After Treatment12 weeks after the last actual dose of active study drug

The percentage of participants with sustained virologic response (plasma Hepatitis C virus ribonucleic acid \[HCV RNA\] level less than the lower limit of quantitation \[\< LLOQ\]) 12 weeks after the last dose of study drug.

Percentage of Participants With On-treatment Virologic Failure During the Double-blind Treatment Period: ABT-450/r/ABT-267 and ABT-333, Plus RBV Arm12 weeks after the last actual dose of active study drug

Virologic failure was defined as rebound (hepatitis C virus ribonucleic acid \[HCV RNA\] ≥ lower limit of quantification \[LLOQ\] after HCV RNA \< LLOQ or increase in HCV RNA of at least 1 log10 IU/mL) or failure to suppress (all on-treatment values of plasma HCV RNA ≥ LLOQ with at least 36 days of treatment) during treatment.

Percentage of Participants With Normalization of Alanine Aminotransferase (ALT) at Final Treatment Visit During the Double-Blind Treatment PeriodAt 12 weeks

Normalization is defined as alanine aminotransferase less than or equal to the upper limit of normal (ULN) at final treatment visit for participants with alanine aminotransferase greater than ULN at baseline.

Percentage of HCV Genotype 1a-infected Participants With Sustained Virologic Response 12 Weeks After Treatment12 weeks after the last actual dose of active study drug

The percentage of participants with sustained virologic response (plasma Hepatitis C virus ribonucleic acid \[HCV RNA\] level less than the lower limit of quantitation \[\< LLOQ\]) 12 weeks after the last dose of study drug.

Percentage of Participants With Virologic Relapse After Treatment: ABT-450/r/ABT-267 and ABT-333, Plus RBV ArmWithin 12 weeks post-treatment

Participants were considered to have virologic relapse after treatment if they had confirmed quantifiable plasma hepatitis C virus ribonucleic acid (HCV RNA) greater than or equal to the lower limit of quantification (≥ LLOQ) between the end of treatment and 12 weeks after the last dose of study drug among participants who completed treatment with HCV RNA \< LLOQ at the end of treatment.
