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 GT 1, 2, 4, 5 or 6 infection and compensated cirrhosis. The primary efficacy objective will be assessed across genotypes, 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 GT 1, 2, 4, 5 or 6 infection and compensated cirrhosis. |

El objetivo principal de eficacia se evaluará en los distintos genotipos en la población conforme al protocolo (PP). Evaluar la seguridad de 8 semanas de tratamiento con la pauta de combinación de glecaprevir/pibrentasvir en adultos con infección crónica por el VHC GT 1, 2, 4, 5 o 6 y cirrosis compensada no tratados previamente. |

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 GT 1, 2, 4, 5 or 6 infection and compensated cirrhosis based on in the intention-to-treat (ITT) population. To assess the percentage of subjects with OTVF across genotypes in the intention-to-treat (ITT) population. To assess the percentage of subjects with post-treatment relapse across genotypes in the intention-to-treat (ITT) population. |
