Arm Intervention/treatment
Experimental: 3-DAA + RBV 600 mg
3-DAA (ombitasvir/paritaprevir/ritonavir [25 mg/150 mg/100 mg once daily] and dasabuvir [250 mg twice daily]) plus RBV (ribavirin [600 mg once daily]) for 12 weeks.
Drug: ombitasvir/paritaprevir/ritonavir and dasabuvir
Tablet; ombitasvir coformulated with paritaprevir and ritonavir, dasabuvir tablet
Other Names:
  • Viekira Pak
  • paritaprevir also known as ABT-450
  • ombitasvir also known as ABT-267
  • dasabuvir also known as ABT-333

Drug: ribavirin

Primary Outcome Measures :
  1. Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12) [ Time Frame: 12 weeks after the last actual dose of study drug ]
    SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification [<LLOQ]) 12 weeks after the last dose of study drug. The primary efficacy endpoint was noninferiority of the percentage of participants who achieved SVR12 in participants in the treatment arm 3-DAA + RBV 600 mg) for 12 weeks compared with the historical control rate for subjects treated with 3-DAA + weight-based RBV for 12 weeks.

  2. Percentage of Participants With Hemoglobin < 10 g/dL During Treatment [ Time Frame: up to 12 weeks ]
    The percentage of participants with hemoglobin <10 g/dL during treatment is provided.

  3. Mean Change in Hemoglobin Values From Baseline to End of Treatment [ Time Frame: Baseline (Day 1) to Weeks 2, 4, 8, and 12, and the Final Treatment Visit (up to 12 weeks) ]
    The mean change in hemoglobin (g/L) from baseline to each study visit and to the final treatment visit (up to 12 weeks) is provided.

Secondary Outcome Measures :
  1. Percentage of Participants With On-treatment Virologic Failure [ Time Frame: Up to 12 weeks ]
    On-treatment virologic failure was defined as confirmed HCV RNA ≥ LLOQ after HCV RNA < LLOQ during treatment; confirmed increase of > 1 log(subscript)10(subscript) IU/mL above the lowest value post-baseline in HCV RNA during treatment; or all on-treatment values of HCV RNA ≥ LLOQ with at least 6 weeks of treatment.

  2. Percentage of Participants With Post-treatment Relapse [ Time Frame: From the end of treatment through 12 weeks after the last dose of study drug ]
    Post-treatment relapse was defined as confirmed HCV RNA ≥ LLOQ between the end of treatment and 12 weeks after the last dose of study drug, excluding reinfection, among participants who completed treatment with HCV RNA levels < LLOQ at the end of treatment.
