A Study to Evaluate the Efficacy and Safety of ABT-493/ABT-530 in Renally Impaired Adults With Chronic Hepatitis C Virus Genotype 1 - 6 Infection

* Chronic hepatitis C virus (HCV) infection * Screening laboratory results indicating HCV genotype 1 - 6 (GT1 - 6) infection. * Subject must be HCV treatment-naïve or have failed previous HCV treatment. * Subjects with underlying chronic renal impairment (estimated glomerular filtration rate (eGFR) \< 30 mL/min/1.73 m2 as estimated by the MDRD method at screening, including those requiring dialysis). * Non-cirrhotic subjects must have documented absence of cirrhosis and subjects with cirrhosis must have documented compensated cirrhosis.

* History of severe, life-threatening or other significant sensitivity to any excipients of the study drug. * Female who is pregnant, planning to become pregnant during the study, or breastfeeding; or male whose partner is 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). * HCV genotype performed during screening indicating co-infection with more than 1 HCV genotype; HCV GT3 infected, treatment-experienced subjects were excluded. * Patients who failed a previous regimen containing protease inhibitor (PIs) and/or nonstructural protein 5A (NS5A) inhibitors.
