Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Age ≥18 years with chronic HCV infection
* Liver biopsy results ≤ 3 years prior to screening indicating the absence of cirrhosis. Alternatively, a non-invasive procedure conducted within 6 months of screening is permitted in countries where allowed
* Monoinfection with HCV genotype (GT) 1a or 1b
* HCV RNA ≥ 104 IU/mL at screening
* Prior treatment and adherence with one course of pegylated interferon alfa and RBV
* The subject's medical records must include sufficient detail of prior treatment with pegylated interferon alfa and RBV (start/stop dates and viral response) to allow for categorization of prior response as either null, partial, breakthrough or relapse.
* Body mass index (BMI) 18-40 kg/m2 inclusive
* Screening ECG without clinically significant abnormalities and with QTcF interval (QT corrected using Fridericia's formula)

≤ 450 msec for males and ≤ 470 msec for females.
* Agree to use two forms of highly effective contraception for the duration of the study and for 7 months after the last dose of study medication. Females of childbearing potential must have a negative pregnancy test at screening and baseline.

Exclusion Criteria

* Discontinuation of prior treatment with pegylated interferon alfa and RBV due to an adverse event, toxicity reasons or were lost to follow-up
* History of significant cardiac disease
* Exceed criteria delineated in Section 4.2 for laboratory measure thresholds related to leukopenia, neutropenia, anemia, thrombocytopenia, and thyroid stimulating hormone (TSH).
* Diagnosis of autoimmune disease, decompensated liver disease, poorly controlled diabetes mellitus, significant psychiatric illness, severe chronic obstructive pulmonary disease (COPD), HIV, hepatitis B virus (HBV), hepatocellular carcinoma or other malignancy (with exception of certain resolved skin cancers), hemoglobinopathy, retinal disease, or are immunosuppressed.
* Current abuse of amphetamines, cocaine, opiates, or alcohol. Methadone use is not allowed, however stable buprenorphine maintenance treatment for ≥ 6 months is permitted.
