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

Inclusion Criteria: * Females were postmenopausal for at least 2 years; 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 indicated HCV single genotype infection for the appropriate treatment arm, without co-infection of any other genotype. * Chronic HCV infection is defined as one of the following: * Positive for anti-HCV antibody (Ab) and/or HCV RNA at least 6 months before Screening. * A liver biopsy consistent with chronic HCV infection. * Agreed to voluntarily sign and date an informed consent form, approved by an Institutional Review Board (IRB)/Independent Ethics Committee (IEC) prior to the initiation of any screening or study specific procedures. * Participants who were able to understand and adhere to the study visit schedule and all other protocol requirements. * Absence of hepatocellular carcinoma (HCC) as indicated by an ultrasound, computed tomography (CT) scan or magnetic resonance imaging (MRI). 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. * Participants co-infected with hepatitis B virus or human immunodeficiency virus. * Use of contraindicated medications or supplements within 2 weeks or 10 half-lives (if known), whichever was longer, prior to the first dose of any study drug. * 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. * Any cause of liver disease other than chronic HCV infection. * Any current or past clinical evidence of Child-Pugh B or C classification or clinical history of decompensated liver disease. * Consideration by the investigator, for any reason, that the participant is an unsuitable candidate to receive ABT-493/ABT-530.
