Primary Outcome Measures
NameTimeMethod
Antiviral activity, as determined by the proportion of non-cirrhotic HCV GT-1b subjects with 12-week sustained virologic response (SVR12), defined as HCV RNA < LLOQ target detected or not detectedPost-treatment Week 12

HCV = Hepatitis C virus; GT = Geno Type; RNA = Ribonucleic acid; LLOQ = Lower limit of quantitation

Secondary Outcome Measures
NameTimeMethod
Proportion of non-cirrhotic HCV GT-1b subjects with psychiatric symptoms (depression or irritability or insomnia) through the end of treatment (maximum of 12 weeks)On-treatment Weeks 1, 2, 4, 8, and 12
Proportion of non-cirrhotic HCV GT-1b subjects with eRVR, defined as HCV RNA < LLOQ target not detectedAt Week 4 and Week 12

eRVR = Extended rapid virologic response

Proportion of non-cirrhotic HCV GT-1b subjects with treatment-emergent cytopenic abnormalities (anemia as defined by Hb < 10 g/dL, and/or neutropenia as defined by ANC < 750 mm3, and/or thrombocytopenia as defined by platelets < 50,000 mm3) on treatmentOn-treatment Weeks 1, 2, 4, 8, and 12

Hb = Hemoglobin; ANC = Absolute neutrophil count

Proportion of non-cirrhotic HCV GT-1b subjects with on-treatment (maximum of 12 weeks) interferon-associated flu-like symptoms (pyrexia or chills or pain)On-treatment Weeks 1, 2, 4, 8, and 12
Proportion of non-cirrhotic HCV GT-1b subjects with on-treatment (maximum of 12 weeks) interferon-associated musculoskeletal symptoms (arthralgia or myalgia or back pain)On-treatment Weeks 1, 2, 4, 8, and 12
Proportion of non-cirrhotic HCV GT-1b subjects with SVR24, defined as HCV RNA < LLOQ target detected or not detectedPost-treatment follow-up Week 24
Frequency of deaths among non-cirrhotic HCV GT-1b subjects through the end of follow-up (maximum of 60 weeks)On-treatment Weeks 1, 2, 4, 8, and 12 and post-treatment weeks 4, 12, 24, 36 and 48
Frequency of Serious adverse events (SAEs) among non-cirrhotic HCV GT-1b subjects through the end of follow-up (maximum of 60 weeks)On-treatment Weeks 1, 2, 4, 8, and 12 and post-treatment weeks 4, 12, 24, 36 and 48
Frequency of drug related Adverse events (AEs) among non-cirrhotic HCV GT-1b subjects through the end of treatment (maximum of 12 weeks)On-treatment Weeks 1, 2, 4, 8, and 12
Frequency of dose reductions and discontinuations due to AEs among non-cirrhotic HCV GT-1b subjects through the end of treatment (maximum of 12 weeks)On-treatment Weeks 1, 2, 4, 8, and 12
Frequency of treatment emergent laboratory abnormalities among non-cirrhotic HCV GT-1b subjects through the end of treatment (maximum of 12 weeks)On-treatment Weeks 1, 2, 4, 8, and 12
Proportion of non-cirrhotic HCV GT-1b subjects with interferon-associated constitutional symptoms (fatigue or asthenia) through the end of treatment (maximum of 12 weeks)On-treatment Weeks 1, 2, 4, 8, and 12
Proportion of non-cirrhotic HCV GT-1b subjects with interferon-associated neurologic symptoms (headache or dizziness) through the end of treatment (maximum of 12 weeks)On-treatment Weeks 1, 2, 4, 8, and 12
