Brief Summary:
A Phase 3b, single arm, open-label, multicenter study in treatment naïve adults with chronic HCV infection and compensated cirrhosis to assess the safety of 8 weeks of treatment with glecaprevir/pibrentasvir and to demonstrate the efficacy of the sustained virologic response 12 weeks post dosing (SVR12) rates of 8 weeks of treatment with glecaprevir/pibrentasvir compared to the historical SVR12 rates of 12 weeks of treatment with glecaprevir/pibrentasvir.

Outcome Measures

Primary Outcome Measures :
  1. Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12) in Hepatitis C Virus (HCV) Genotype (GT) 1,2,4,5 and 6-infected Participants in the Per Protocol (PP) Population [ Time Frame: 12 weeks after last 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; less than 15 IU/mL) 12 weeks after the last dose of study drug. Efficacy of the 8-week treatment duration compared to the historical 12-week treatment duration was demonstrated if the lower bound of the 2-sided 95% confidence interval (CI) for the percentage of participants with HCV GT1, GT2, GT4, GT5, or GT6 infection in the 8 week treatment duration achieving SVR12 was greater than 94% in the PP population. Efficacy analyses were performed following a fixed-sequence testing procedure to control the type I error rate. The percentage of participants achieving SVR12 was summarized with a 2-sided 95% CI, calculated using the normal approximation to the binomial distribution. If the number of participants who failed to achieve SVR12 rate was less than 5, the Wilson's score method was used to calculate the CI.

  2. Percentage of Participants With SVR12 in HCV GT 1,2,4,5 and 6-infected Participants in the Intent-To-Treat (ITT) Population [ Time Frame: 12 weeks after last dose of study drug ]
    SVR12 was defined as HCV RNA level less than the LLOQ (less than 15 IU/mL) 12 weeks after the last dose of study drug. Efficacy of the 8-week treatment duration compared to the historical 12-week treatment duration was demonstrated if the lower bound of the 2-sided 95% CI for the percentage of participants with HCV GT1, GT2, GT4, GT5, or GT6 infection in the 8 week treatment duration achieving SVR12 was greater than 93% in the ITT population. Primary efficacy analyses were performed following a fixed-sequence testing procedure to control the type I error rate. The percentage of participants achieving SVR12 was summarized with a 2-sided 95% CI, calculated using the normal approximation to the binomial distribution. If the number of participants who failed to achieve SVR12 rate was less than 5, the Wilson's score method was used to calculate the CI.


Secondary Outcome Measures :
  1. Percentage of Participants With SVR12 in HCV GT1-6-infected Participants in the PP Population [ Time Frame: 12 weeks after last dose of study drug ]
    SVR12 was defined as HCV RNA level less than the LLOQ (less than 15 IU/mL) 12 weeks after the last dose of study drug. Efficacy of the 8-week treatment duration compared to the historical 12-week treatment duration was demonstrated if the lower bound of the 2-sided 95% CI for the percentage of participants with HCV GT1, GT2, GT3, GT4, GT5, or GT6 infection in the 8 week treatment duration achieving SVR12 was greater than 94% in the PP population. These efficacy analyses were performed only if success was demonstrated for both primary efficacy analyses, following a fixed-sequence testing procedure.

  2. Percentage of Participants With SVR12 in HCV GT1-6-infected Participants in the ITT Population [ Time Frame: 12 weeks after the last dose of study drug ]
    SVR12 was defined as HCV RNA level less than the LLOQ (less than 15 IU/mL) 12 weeks after the last dose of study drug. Efficacy of the 8-week treatment duration compared to the historical 12-week treatment duration was demonstrated if the lower bound of the 2-sided 95% CI for the percentage of participants with HCV GT1, GT2, GT3, GT4, GT5, or GT6 infection in the 8 week treatment duration achieving SVR12 was greater than 93% in the ITT population. These efficacy analyses were performed only if success was demonstrated for both primary efficacy analyses, following a fixed-sequence testing procedure.

  3. Percentage of Participants With On-treatment Virologic Failure in the ITT Population [ Time Frame: 8 weeks on treatment ]
    On-treatment virologic failure was defined as confirmed HCV RNA ≥ 100 IU/mL 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 HCV RNA ≥ LLOQ at end of treatment with at least 6 weeks of treatment.

  4. Percentage of Participants With Post-treatment Relapse [ Time Frame: Up to 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 among participants who completed treatment as planned (defined as study drug duration ≥ 52 days for participants assigned to 8 weeks of treatment) and with HCV RNA levels < LLOQ at the end of treatment excluding participants who had been reinfected.

  5. Percentage of HCV GT3-infected Participants Who Achieved SVR12 in the PP Population [ Time Frame: 12 weeks after the last dose of study drug ]
    SVR12 was defined as HCV RNA level less than the LLOQ (less than 15 IU/mL) 12 weeks after the last dose of study drug.

  6. Percentage of HCV GT3-infected Participants Who Achieved SVR12 in the ITT Population [ Time Frame: 12 weeks after the last dose of study drug ]
    SVR12 was defined as HCV RNA level less than the LLOQ (less than 15 IU/mL) 12 weeks after the last dose of study drug.
