Primary Outcome Measures:
  • Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment [ Time Frame: 12 weeks after the last actual dose of study drug ] [ Designated as safety issue: No ]
    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:
  • Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment in the 24-week Arm Compared to the 12-week Arm [ Time Frame: 12 weeks after the last actual dose of study drug ] [ Designated as safety issue: No ]
    A sustained virologic response is defined as plasma Hepatitis C virus ribonucleic acid (HCV RNA) less than the lower limit of quantification (< LLOQ) 12 weeks after the last dose of study drug.

  • Percentage of Participants in Each Arm With On-treatment Virologic Failure During the Treatment Period [ Time Frame: Baseline (Day 1), and Treatment Weeks 1, 2, 4, 6, 8, 10, 12, 16, 20, and 24 ] [ Designated as safety issue: No ]
    Virologic failure during treatment was defined as rebound (confirmed HCV RNA greater than or equal to the lower limit of quantitation [≥ LLOQ] after HCV RNA < LLOQ during treatment, or confirmed increase from the lowest value post baseline in HCV RNA [2 consecutive HCV RNA measurements > 1 log(subscript)10(subscript) IU/mL above the lowest value post baseline] at any time point during treatment), or fail to suppress (HCV RNA ≥ LLOQ persistently during treatment with at least 6 weeks [≥ 36 days] of treatment).

  • Percentage of Participants With Virologic Relapse After Treatment [ Time Frame: within 12 weeks after the last dose of study drug ] [ Designated as safety issue: No ]
    Participants were considered to have virologic relapse after treatment if they had confirmed quantifiable plasma Hepatitis C virus ribonucleic acid (HCV RNA) ≥ 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.

Detailed Description:

During the treatment period of the study, participants received treatment with ABT-450/ritonavir/ABT-267 and ABT-333 coadministered with RBV for either 12 or 24 weeks. Upon completing the treatment period or premature discontinuation of the treatment period, participants entered a 48-week post-treatment period. Safety and efficacy data through 24 January 2014 are included in the interim analysis, which was conducted after all participants completed the post-treatment week 12 visit or discontinued from the study.
