- Proportion of treated subjects in each of the naive arms with sustained virologic response (SVR12) [ Time Frame: Post treatment 12 week ]SVR12 is defined as Hepatitis C virus ribonucleic acid (HCV RNA) < Limit of Quantification (LOQ) target detected or target not detected (LOQ TD/TND)
- Proportion of treated subjects in each of the experienced arms with SVR12 [ Time Frame: Post treatment 12 Week ]
- Proportion of subjects in each arm who achieve HCV RNA < LOQ TD/TND [ Time Frame: Weeks: 1, 2, 4, 6, 8, and 12; Post treatment Weeks 4 (SVR4), 8 (SVR8) and 24 (SVR24) ]
- Proportion of subjects in each arm who achieve HCV RNA < LOQ TND [ Time Frame: Weeks: 1, 2, 4, 6, 8, and 12; Post treatment Weeks 4 (SVR4), 8 (SVR8), 12 (SVR12) and 24 (SVR24) ]
- Safety as measured by frequency of Serious Adverse Events(SAEs)and discontinuations due to Adverse Events(AEs) [ Time Frame: Up to end of treatment (week 12) + 7 days ]
- Proportion of subjects with anemia defined as Hg < 10 g/dL on-treatment and Hg ≥ 10 g/dL at baseline in each arm within each cohort [ Time Frame: Up to end of treatment (week 12) + 7 days ]
- Differences in rates of selected Grade 3 - 4 laboratory test result abnormalities [ Time Frame: Up to end of treatment (week 12) + 7 days ]
- Proportion of subjects achieving SVR12 associated with HCV geno subtype 1a vs 1b [ Time Frame: Post treatment 12 Week ]

Inclusion Criteria:
- Subjects chronically infected with HCV genotype 1
- Subjects with compensated cirrhosis
- HCV RNA ≥ 10,000 IU/mL at screening
- Treatment-naïve subjects with no previous exposure to an interferon formulation (ie, IFNα, pegIFNα), Ribavirin (RBV), or HCV Direct Acting Antivirals (DAA) (protease, polymerase inhibitor, etc.)
- Treatment-experienced subjects are eligible including exposure to anti-HCV agents of a mechanistic class other than those contained in the Daclatasvir (DCV) / Asunaprevir (ASV) /BMS-791325 triple regimen is permitted. Examples of permitted agents include, but are not limited to nucleoside/nucleotide inhibitors of nonstructural protein 5B (NS5B) polymerase, inhibitors of cyclophilin, or inhibitors of microRNA.
Exclusion Criteria:
- Subjects without cirrhosis
