A Phase 2B, Randomized Study to Evaluate the Safety and Efficacy of Pegylated Interferon Lambda (BMS-914143) Administered With Ribavirin Plus a Single Direct Antiviral Agent (BMS-790052 or BMS-650032) Versus Pegasys Administered With Ribavirin (Part A) and of Pegylated Interferon Lambda (BMS-914143) Administered With or Without Ribavirin Plus 2 Direct Antiviral Agents (BMS-790052 and BMS-650032) (Part B) in Chronic Hepatitis C Genotype-1 Treatment naïve Subjects

Secondary Outcomes

• Serum HCV Ribonucleic acid (RNA) levels over time(Days 1, 3, Weeks 1, 2, 4, 6, 8, 12, 16, 20, and end of treatment (Week 16, 24 or 48 depending on treatment assignment))
• Proportion of subjects with either a 2-log or greater decrease in Hepatitis C virus (HCV) Ribonucleic acid (RNA) levels from baseline or undetectable levels of HCV RNA(Weeks 2, Weeks 4 and Weeks 12)
• Proportion of subjects with undetectable HCV RNA at the end of treatment that develop detectable levels of HCV RNA in the post-treatment follow-up period(Post-treatment Week 48)
• Time to viral clearance, defined as an absence of detectable HCV RNA(Day 1, 3, Week 1, 2, 4, 6, 8, 12, 24, 36, end of treatment (Week 48), Post-Treatment at Week 4, 12, 24, 36, 48, and 56)
• Serum levels of pegIFNλ and pegIFNα-2a and plasma levels of BMS-790052 and BMS-650032: In PK sub-study group Maximum observed serum/plasma concentration (Cmax)(Cmax will be determined at Dose 5 (Study Visit Week 4: 0 - 12 h for BMS-650032, 0 - 24 h for BMS-790052, and 0 - 168 h for pegIFNλ and pegIFNα-2a))
• Serum levels of pegIFNλ and pegIFNα-2a and plasma levels of BMS-790052 and BMS-650032: In PK sub-study group Time to maximum concentration (Tmax)(Tmax will be determined at Dose 5 (Study Visit Week 4: 0 - 12 h for BMS-650032, 0 - 24 h for BMS-790052, and 0 - 168 h for pegIFNλ and pegIFNα-2a))
• Serum levels of pegIFNλ and pegIFNα-2a and plasma levels of BMS-790052 and BMS-650032: In PK sub-study group Minimal observed serum/plasma concentration (Cmin)(Cmin will be determined at Dose 5 (Study Visit Week 4: 0 - 12 h for BMS-650032, 0 - 24 h for BMS-790052, and 0 - 168 h for pegIFNλ and pegIFNα-2a))
• Serum levels of pegIFNλ and pegIFNα-2a and plasma levels of BMS-790052 and BMS-650032: In PK sub-study group Area under the serum/plasma concentration-time curve during one dose interval AUC(TAU)(AUC(TAU) will be determined at Dose 5 (Study Visit Week 4: 0 - 12 h for BMS-650032, 0 - 24 h for BMS-790052, and 0 - 168 h for pegIFNλ and pegIFNα-2a))
• Serum levels of pegIFNλ and pegIFNα-2a and plasma levels of BMS-790052 and BMS-650032: In all subjects, trough concentrations will be assessed (Ctrough)(Troughs at baseline (week 0), weeks 2, 4, 8, 12, 16, and 24)
• Proportion of subjects with 12-week sustained virologic response (SVR12), defined as undetectable HCV RNA(At end of treatment (maximum of 48 weeks) and follow-up Week 12)
• Proportion of subjects with 4-week sustained virologic response (SVR4), defined as undetectable HCV RNA(At end of treatment (maximum of 48 weeks) and follow-up Week 4)
• Proportion of HCV genotype 1 subjects with Protocol definition of virologic response (PDR) for Part A and Part B(Weeks 4, Weeks 12 and post-treatment Weeks 24)
• Proportion of subjects with viral breakthrough, defined as confirmed > 1 log10 increase in HCV RNA over nadir or confirmed HCV RNA ≥ Lower limit of quantitation (LLOQ) after confirmed undetectable HCV RNA while on treatment(Post-treatment Week 48)
• Proportion of subjects with undetectable HCV RNA over time(Days 1, 3, Weeks 1, 2, 4, 6, 8, 12, 16, 20, and end of treatment (Week 16, 24 or 48 depending on treatment assignment))
