A Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of ABT-493 and ABT-530 With and Without Ribavirin in Adults With HCV Who Failed a Prior DAA Containing Therapy

A Randomized, Open-Label, Multicenter Study to Evaluate the Efficacy, Safety, and Pharmacokinetics of Co-Administration of ABT-493 and ABT-530 (or ABT-493/ABT-530) With and Without Ribavirin in Adults With Chronic Hepatitis C Virus (HCV) Infection Who Failed a Prior Direct-Acting Antiviral Agent (DAA)-Containing Therapy

The purpose of this study is to assess the efficacy and safety of ABT-493 and ABT-530 with or without ribavirin (RBV) in participants with chronic hepatitis C virus, (HCV)-infection who previously failed treatment with a direct acting antiviral (DAA)-containing regimen.

Inclusion Criteria:

1. Patients from 18 to 70 years in Arms A, B, and C; patients 18 years of age or older in Arms D and E.
2. Previous treatment with DAA-containing regimen for chronic hepatitis C virus (HCV) infection resulting in either on-treatment virologic failure or post-treatment relapse
3. Chronic HCV genotype (GT) 1, 4, 5, or 6-infection (GT4-6 in Arms D and E)

Exclusion Criteria:

1. History of severe, life-threatening or other significant sensitivity to any drug
2. 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
3. Recent (within 6 months prior to study drug administration) history of drug or alcohol abuse that could preclude adherence to the protocol
4. Positive for hepatitis B surface antigen (HBsAg) or anti-human immunodeficiency virus antibody (HIV Ab)
5. Co-infection with more than one HCV genotype
