Outcomes
Primary Outcomes
Proportion of treated subjects randomized to Active Dual therapy with Sustained Virologic Response (SVR12)
Time Frame: Post-treatment Week 12

- On treatment safety, as measured by frequency of serious adverse events (SAEs) and discontinuations due to adverse events (AEs)(Post-treatment week 12)
- Differences in rates of selected Grade 3-4 laboratory abnormalities for hematology between treatments (DCV + Asunaprevir (ASV) vs PBO)(first 12 weeks on treatment)
