Brief Summary:
This was a multicenter study evaluating the efficacy and safety of ombitasvir/paritaprevir/ritonavir and dasabuvir co-administered with ribavirin (RBV) for 12 weeks in treatment naïve and pegylated-interferon alfa-2a or alfa-2b (pegIFN)/RBV treatment-experienced, cirrhotic HCV genotype 1b-infected adults.

Condition or disease Intervention/treatment Phase
Chronic Hepatitis C Virus (HCV) Infection Drug: Ombitasvir/Paritaprevir/Ritonavir Drug: Dasabuvir Drug: Ribavirin (RBV) Phase 3

Detailed Description:
The primary objective of this study was to assess the safety and efficacy (the percentage of participants achieving a 12-week sustained virologic response (SVR12), [HCV ribonucleic acid (RNA) < lower limit of quantification (LLOQ) 12 weeks following treatment]) of co-formulated ombitasvir, paritaprevir, and ritonavir (ombitasvir/paritaprevir/r) and dasabuvir co-administered with RBV for 12 weeks in HCV genotype 1b-infected adult participants with compensated cirrhosis. The secondary objectives of this study were to assess the number and percentage of participants with virologic failure during treatment and the percentage of participants with relapse post-treatment.

Tablet




Primary Outcome Measures :
  1. Percentage of Participants With Sustained Virologic Response 12 Weeks (SVR12) Post-treatment [ Time Frame: Post-treatment Day 1 to Post-treatment Week 12 ]
    Sustained Virologic Response 12 (SVR12) is defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) less than the lower limit of quantification (< LLOQ; < 25 IU/mL) 12 weeks after the last dose of study drug. Participants with missing data were imputed as failures.


Secondary Outcome Measures :
  1. Percentage of Participants With On-Treatment Virologic Failure [ Time Frame: Day 1 through Week 12 ]
    On-Treatment Virologic Failure is defined as confirmed HCV RNA >= LLOQ after HCV RNA < LLOQ during treatment, or confirmed increase from nadir (local minimum value) in HCV RNA [2 consecutive HCV RNA measurements > 1 log10 IU/mL above nadir] at any time point during treatment, or failure to suppress during treatment [all on-treatment values of HCV RNA >= LLOQ] with at least 6 weeks [defined as active study drug duration ≥ 36 days] of treatment.

  2. Percentage of Participants With Post-Treatment Relapse [ Time Frame: Post-treatment Day 1 to Post-treatment Week 12 ]
    Post- Treatment Relapse is defined as confirmed HCV RNA >= LLOQ between end of treatment and 12 weeks after last actual dose of active study drug [up to and including the SVR12 assessment time point] for a participant with HCV RNA < LLOQ at Final Treatment Visit who completes treatment.
