The purpose of this study is to determine whether a regimen consisting of daclatasvir and
asunaprevir is effective in treatment-naive patients with chronic hepatitis genotype 1b
infection.
Primary Outcomes
Description: HCV RNA < Lower limit of quantitation (LLOQ) target detected (TD) or target not detected (TND) at follow-up Week 12
Measure: Proportion of treated subjects randomized to Active Dual therapy with Sustained Virologic Response (SVR12)
Time: Post-treatment Week 12
Secondary Outcomes
Measure: Proportion of subjects with anemia on active Dual therapy Time: Post-treatment Week 12
Measure: Proportion of subjects with neutropenia on active Dual therapy Time: Post-treatment Week 12
Measure: Proportion of subjects with thrombocytopenia on active Dual therapy Time: Post-treatment Week 12
Measure: On treatment safety, as measured by frequency of serious adverse events (SAEs) and discontinuations due to adverse events (AEs) Time: Post-treatment week 12
Measure: Differences in rates of selected Grade 3-4 laboratory abnormalities for hematology between treatments (DCV + Asunaprevir (ASV) vs PBO) Time: first 12 weeks on treatment
Measure: Differences in rates of selected Grade 3-4 laboratory abnormalities for liver function between treatments (DCV + Asunaprevir (ASV) vs PBO) Time: first 12 weeks on treatment
Measure: Proportion of subjects with SVR12 by the rs12979860 single nucleotide polymorphism (SNP) in the interleukin (IL) -28B gene for each cohort Time: Post-treatment visit week 12
Measure: Proportion of subjects with hepatitis C virus (HCV) RNA < LLOQ-TD/TND in each arm at various intervals after the initiation of active Dual therapy Time: post-treatment visit Week 24
Measure: Proportion of subjects who achieve HCV RNA < LLOQ-TND at each arm at various intervals after the initiation of active Dual therapy Time: post-treatment visit Week 24
Measure: Proportion of treated subjects with SVR12 for subjects randomized to placebo Time: Post-treatment visit week 12
