Primary Outcome Measures :
  1. Percentage of Non-cirrhotic Treatment-Naïve Participants Who Are Eligible for Interferon (IFN)-Based Therapy and Who Have High Viral Load in the DB Active Treatment Group With a Sustained Virologic Response 12 Weeks Post-treatment [ Time Frame: 12 weeks after the last dose of study drug ]
    The percentage noncirrhotic treatment-naïve participants who were eligible for IFN-based therapy and who had high viral load at baseline (HCV RNA ≥ 100,000 IU/mL) in the DB active treatment group 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 active study drug (SVR12). Among noncirrhotic treatment-naïve participants who were eligible for IFN-based therapy and who had high viral load at baseline, superiority of Arm A to a clinically relevant threshold based on historical SVR rate with telaprevir plus pegylated interferon alpha/ribavirin (pegIFN/RBV) in treatment-naïve, non-cirrhotic patients with high viral load; the lower bound of 95% confidence interval (LCB) had to exceed 63% to achieve superiority. The 95% confidence interval was calculated using the normal approximation to the binomial distribution.


Secondary Outcome Measures :
  1. Percentage of Participants in the Active Treatment Group With On-treatment Virologic Failure During Treatment [ Time Frame: up to 12 weeks ]

    On-treatment virologic failure among all randomized non-cirrhotic participants who received at least one dose of DB ABT-450/r/ABT-267 and all enrolled participants with compensated cirrhosis who received at least one dose of OL ABT-450/r/ABT-267. On-treatment virologic failure is defined as the occurrence of at least one of the following:

    • confirmed HCV RNA ≥ LLOQ (defined as 2 consecutive HCV RNA measurements ≥ LLOQ) at any point during treatment after HCV RNA < LLOQ (rebound), or
    • confirmed increase from nadir in HCV RNA (defined as 2 consecutive HCV RNA measurements > 1 log10 IU/mL above nadir) at any time point during treatment (rebound), or
    • HCV RNA ≥ LLOQ persistently during treatment with at least 6 weeks (≥ 36 days) of treatment (failure to suppress).

    The 95% confidence interval was calculated using the Wilson's score method.


  2. Percentage of Participants in the Substudy 1 Arm A Active Treatment Group With On-treatment Virologic Failure During Treatment, by Subpopulation [ Time Frame: up to 12 weeks ]
    On-treatment virologic failure among all randomized non-cirrhotic participants who received at least one dose of DB ABT-450/r/ABT-267 in the following subpopulations: noncirrhotic treatment-naïve (T-naïve) participants with a high baseline (BL) viral load (HCV RNA ≥ 100,000 IU/mL) who are eligible for IFN-based therapy (IFN-BT), a low viral load (HCV RNA < 100,000 IU/mL), or who are ineligible for IFN-BT; noncirrhotic treatment-experienced (T-exp) participants who relapsed after prior IFN-BT, who were nonresponders to prior IFN-BT, or who were intolerant to IFN-BT. On-treatment virologic failure is defined in Outcome measure 2. The 95% confidence interval was calculated using the Wilson's score method.

  3. Percentage of Participants in the Active Treatment Group With Post-treatment Relapse [ Time Frame: within 12 weeks after last dose of study drug ]
    Post-treatment relapse among all randomized non-cirrhotic participants who received at least one dose of DB ABT-450/r/ABT-267 and completed treatment, and all enrolled participants with compensated cirrhosis who received at least one dose of OL ABT-450/r/ABT-267 and completed treatment. Relapse was defined as confirmed HCV RNA ≥ LLOQ (defined as 2 consecutive HCV RNA measurements ≥ LLOQ) between the final treatment visit and 12 weeks after the last dose of study drugs among participants completing treatment and with HCV RNA < LLOQ at the final treatment visit and at least one post-treatment HCV RNA value. The 95% confidence interval was calculated using the Wilson's score method.

  4. Percentage of Participants in Substudy 1 Arm A Active Treatment Group With Post-treatment Relapse, by Subpopulation [ Time Frame: within 12 weeks after last dose of study drug ]

    Post-treatment relapse among all randomized non-cirrhotic participants who received at least one dose of DB ABT-450/r/ABT-267 and completed treatment, in the following subpopulations: noncirrhotic treatment-naïve (T-naïve) participants with a high baseline (BL) viral load (HCV RNA ≥ 100,000 IU/mL) who are eligible for IFN-based therapy (IFN-BT), a low BL viral load (HCV RNA < 100,000 IU/mL), or who are ineligible for IFN-BT; noncirrhotic treatment-experienced (T-exp) participants who relapsed after prior IFN-BT, who were nonresponders to prior IFN-BT, or who were intolerant to IFN-BT.

    Relapse was defined as confirmed HCV RNA ≥ LLOQ (defined as 2 consecutive HCV RNA measurements ≥ LLOQ) between the final treatment visit and 12 weeks after the last dose of study drugs among participants completing treatment and with HCV RNA < LLOQ at the final treatment visit and at least one post-treatment HCV RNA value. The 95% confidence interval was calculated using the Wilson's score method.


  5. Percentage of Participants in the Active Treatment Group With Sustained Virologic Response 12 Weeks Post-treatment [ Time Frame: 12 weeks after last dose of study drug ]
    Sustained virologic response (plasma HCV RNA level < LLOQ) 12 weeks after the last dose of study drug for all randomized non-cirrhotic participants who received at least one dose of DB ABT-450/r/ABT-267 and for all enrolled participants with compensated cirrhosis who received at least one dose of open-label ABT-450/r/ABT-267. The 95% confidence interval was calculated using the Wilson's score method.

  6. Percentage of Participants in Substudy 1 Arm A Active Treatment Group With Sustained Virologic Response 12 Weeks Post-Treatment, by Subpopulation [ Time Frame: 12 weeks after last dose of study drug ]
    Sustained virologic response (plasma HCV RNA level < LLOQ) 12 weeks after the last dose of study drug for all randomized non-cirrhotic participants who received at least one dose of DB ABT-450/r/ABT-267 in the following subpopulations: noncirrhotic T-naïve participants with a high BL viral load (HCV RNA ≥ 100,000 IU/mL) who are eligible for IFN-BT; noncirrhotic T-naïve participants with low BL viral load (HCV RNA < 100,000 IU/mL); noncirrhotic T-naïve participants who are ineligible for IFN-BT; noncirrhotic T-exp participants who relapsed after prior IFN-BT; noncirrhotic T-exp participants who were nonresponders to prior IFN-BT; noncirrhotic T-exp participants who were intolerant to IFN-BT. The 95% confidence interval was calculated using the Wilson's score method.
