Inclusion criteria

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

Exclusion Criteria:

  • Subjects without cirrhosis
  • Liver or any other organ transplant
  • Current or known history of cancer within 5 years prior to screening
  • Documented or suspected hepatocellular carcinoma(HCC)
  • Evidence of decompensated liver disease including, but not limited to, radiologic criteria, a history or presence of ascites, bleeding varices, or hepatic encephalopathy

What researchers measure

Primary outcomes

  1. Proportion of treated subjects in each of the naive arms with sustained virologic response (SVR12)

    SVR12 is defined as Hepatitis C virus ribonucleic acid (HCV RNA) \< Limit of Quantification (LOQ) target detected or target not detected (LOQ TD/TND)

    Time frame: Post treatment 12 week

Secondary outcomes

  1. Proportion of treated subjects in each of the experienced arms with SVR12

    Time frame: Post treatment 12 Week

  2. 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)

  3. 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)

  4. 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

  5. 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

  6. Differences in rates of selected Grade 3 - 4 laboratory test result abnormalities

    Time frame: Up to end of treatment (week 12) + 7 days

  7. Proportion of subjects achieving SVR12 associated with HCV geno subtype 1a vs 1b

    Time frame: Post treatment 12 Week

  8. Proportion of subjects in each arm achieving SVR12 associated with IL28B rs12979860 single nucleotide polymorphism(SNP) status (CC genotype or non-CC genotype)

    Time frame: Post treatment 12 Week
