Percentage of Participants Achieving Rapid Viral Response
Tidsramme: Week 4
|
Rapid viral response (RVR) is defined as undetectable hepatitis C virus ribonucleic acid (HCV RNA) at Week 4. Serum HCV RNA levels were measured using Roche COBAS TaqMan HCV Auto assay.
The limit of quantification was 1.2 log IU/mL (15 IU/mL) and the limit of detection was <1.2 log IU/mL, but with no specific value.
The Data-As-Observed (DAO) approach was used to handle missing data.

Change From Baseline in HCV RNA in log10 at Week 4
Tidsramme: Baseline and Week 4
|
Change from baseline in HCV RNA at Week 4 was calculated by subtracting Week 4 HCV RNA level from Baseline HCV RNA level.
HCV RNA is measured as International Units per milliliter (IU/mL).
Serum HCV RNA levels were measured using Roche COBAS TaqMan HCV Auto assay.
The DAO approach was used to handle missing data.
