Key inclusion criteria
Inclusion Criteria Part 3:

* Males or females of non-childbearing potential aged 18 to 65 years. Females must be surgically sterile, or post-menopausal for at least 12 months. Females of child-bearing potential may be enrolled provided they use two methods of acceptable contraception.
* Diagnosed with chronic liver disease consistent with chronic hepatitis C infection, genotype-1, for at least 6 months.
* Genotype 1 Patients who are HCV treatment-naive, with no history of exposure to interferon, ribavirin, or direct antivirals; OR Genoytpe 2 or 3 patients who have previously been treated with interferon.
* Otherwise healthy as determined at screening.
* At least one measurement of serum HCV RNA of = 100,000 IU/mL measured during Screening by the COBAS AmpliPrep/COBAS TaqMan HCV.
* ALT and AST measurement at Screening < 5 times of ULN.
* Liver biopsy obtained within 2 years (24 calendar months) prior to Screening with a fibrosis classification of non-cirrhotic as judged by a local pathologist. Incomplete cirrhosis (Ishak 5) is also considered as cirrhosis. If no history of liver biopsy, a study qualifying biopsy must be performed during the screening period, prior to randomization.
* Negative pregnancy test (for all females) at Screening and Day -1.
* All male patients with female partners of child-bearing potential must use two acceptable methods of contraception (one of which must be a barrier method), during and for 3 months after participation in the study.
* A body mass index (BMI) of = 18 kg/m2, but not exceeding 36.
* Able to abstain from any alcohol (including alcohol-containing products) and able to limit caffeine consumption to two 8-ounce cups of coffee or the equivalent per day, from 72 hours before receiving study drug through the end of the study (Day 56 or early termination).

* Positive results for drugs of abuse at Screening.
* History of clinically significant drug allergy to nucleoside/nucleotide analogues.
* Donation or loss of more than 400 mL blood within 2 months prior to anticipated dose administration.
* Participation in a clinical study with an investigational drug, biologic, or device within 3 months prior to anticipated dose administration.
* Males whose female partner is pregnant.
