A Study to Evaluate the Efficacy and Safety of ABT-493/ABT-530 in Japanese Adults With Genotype 2 Chronic Hepatitis C Virus Infection

Inclusion Criteria: * Females were postmenopausal for at least 2 years prior to screening; surgically sterile or had a vasectomized partner; or, if of childbearing potential and sexually active with a male partner, were currently using at least 1 effective method of birth control at the time of Screening and agreed to practice 1 effective method of birth control from Screening through 30 days after stopping study drug. Sexually active males were surgically sterile or, if sexually active with a female partner of childbearing potential, agreed to practice 1 effective form of birth control from Screening through 30 days after stopping study drug. * Screening central laboratory result indicating HCV GT-2 infection without co-infection of any other genotype. * Participant has positive anti-HCV antibody (Ab) and plasma HCV RNA viral load greater than or equal to 1000 IU/mL at Screening Visit. * Chronic HCV infection defined as one of the following: * Positive for anti-HCV Ab and/or HCV RNA at least 6 months before Screening; or * A liver biopsy consistent with chronic HCV infection. * Participant must be HCV treatment-naïve (i.e., patient has not received a single dose of any approved or investigational DAA) and non-cirrhotic. Prior HCV treatment using IFNs with or without ribavirin is acceptable. Previous HCV Interferon (IFN) based treatment must have been completed greater than or equal to 2 months prior to screening. Exclusion Criteria: * Females who were pregnant or planned to become pregnant, or breastfeeding or males whose partner was pregnant or planning to become pregnant during the study. * Recent (within 6 months prior to study drug administration) history of drug or alcohol abuse that could preclude adherence to the protocol in the opinion of the investigator. * Positive test result at Screening for hepatitis B surface antigen (HBsAg) or anti human immunodeficiency virus antibody (HIV Ab). * Requirement for and inability to safely discontinue contraindicated medications or supplements at least 2 weeks or 10 half-lives (whichever is longer) prior to the first dose of any study drug. * Clinically significant abnormalities, other than HCV-infection, based upon the results of a medical history, physical examination, vital signs, laboratory profile, and a 12-lead electrocardiogram (ECG) that make the participant an unsuitable candidate for this study in the opinion of the investigator, including, but not limited to: * Uncontrolled diabetes as defined by a glycated hemoglobin (hemoglobin A1C) level \> 8.5% at the Screening Visit. * Active or suspected malignancy or history of malignancy (other than basal cell skin cancer or cervical carcinoma in situ) in the past 5 years, or any history of hepatocellular carcinoma (HCC). * Uncontrolled cardiac, respiratory, gastrointestinal, hematologic, neurologic, psychiatric, or other medical disease or disorder, which is unrelated to the existing HCV infection. * Any cause of liver disease other than chronic HCV-infection, including but not limited to the following: * Hemochromatosis, alpha-1 antitrypsin deficiency, Wilson's disease, autoimmune hepatitis, alcoholic liver disease, or steatohepatitis considered to be the primary cause of the liver disease rather than concomitant/incidental with HCV infection.
