E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate the non-inferiority of the SVR12 rates of 8 weeks of treatment with the glecaprevir/pibrentasvir combination regimen to the historical SVR12 rate of 12 weeks of treatment with the glecaprevir/pibrentasvir in treatment naïve adults with chronic HCV infection and compensated cirrhosis. The primary efficacy objective will be assessed in the Per-Protocol (PP) population.
To assess the safety of 8 weeks of treatment with the glecaprevir/pibrentasvir combination regimen in treatment naïve adults with chronic HCV and compensated cirrhosis. |
|
E.2.2 | Secondary objectives of the trial |
To demonstrate the non-inferiority of the SVR12 rates of 8 weeks of treatment with the glecaprevir/pibrentasvir combination regimen to the historical SVR12 rate of 12 weeks of treatment with the glecaprevir/pibrentasvir in treatment naïve adults with chronic HCV infection and compensated cirrhosis in the intention-to-treat (ITT) population.
To assess the percentage of subjects with OTVF in the intention-to-treat (ITT) population.
To assess the percentage of subjects with post-treatment relapse in the intention-to-treat (ITT) population. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy variable is the percentage of HCV GT1, 2, 4, 5 and 6-infected subjects who achieve SVR12 (HCV RNA < LLOQ 12 weeks after the last actual dose of study drug). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
12 weeks following the last dose of study drug |
|
E.5.2 | Secondary end point(s) |

- The percentage of subjects (for HCV GT1, 2, 4, 5 and 6-infected, HCV GT3-infected and HCV GT1-6-infected) with HCV on-treatment virologic failure.
- The percentage of subjects (for HCV GT1, 2, 4, 5 and 6-infected, HCV GT3-infected and HCV GT1-6-infected) with post-treatment HCV relapse. |
