A Study of the Safety, Tolerability, Pharmacokinetics, and Antiviral Activity of JNJ-47910382 at Different Doses and Dose Regimens in Asian Genotype-1, Chronic, HCV-Infected Patients

Inclusion Criteria: * Documented chronic HCV infection (diagnosis of hepatitis C \>= 6 months before the screening period) * HCV geno- and subtype of 1a or 1b (Panel 1) or 1b (Panels 2 and 3) * Patient has never received pegylated interferon, ribavirin, or any other approved or investigational antiviral treatment for chronic HCV infection * Patient with HCV ribonucleic acid (RNA) level of \>100,000 IU/mL at screening (as assessed by standard quantitative in vitro nucleic acid amplification assay) * A Body Mass Index (BMI, weight in kg divided by the square of height in meters) of 18.0 to 32.0 kg/m2, extremes included * A body weight above 50 kg * Normal 12-lead electrocardiogram (ECG) at screening Exclusion Criteria: * Evidence of or documented liver cirrhosis * Evidence of decompensated liver disease * Evidence of any other cause of significant liver disease in addition to hepatitis C * History or evidence of current use of alcohol, barbiturate, amphetamine, recreational or narcotic drug use, which in the Investigator's opinion would compromise patient's safety and/or compliance with the study procedures * A positive urine drug (with exclusion of methadone or equivalent) test at study screening * Patient with protocol-defined laboratory abnormalities at screening * Patient coinfected with HIV-1 or HIV-2, or hepatitis A or B virus infection, or active tuberculosis at study screening * Patient infected/coinfected with non-genotype 1 HCV at study screening * Patient with any cardiac disease at screening, or any active clinically significant disease (eg, cardiac dysfunction, cardio(myo)pathy, cardiac insufficiency), or medical history or physical examination findings during screening that, in the Investigator's opinion, would compromise the outcome of the trial * Patient having uncontrolled/unstable disease such as diabetes, epilepsy, a manifest psychiatric disease, or thyroid disease or disorders * Patient with non-stable methadone (or equivalent drug) use
