Brief Summary
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.

Outcomes
Primary Outcomes
Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)
Time Frame: 12 weeks after the last actual dose of study drug
SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification \[\<LLOQ\]) 12 weeks after the last dose of study drug.
Secondary Outcomes
- Percentage of Participants With On-treatment Virologic Failure(Day 3, Treatment Weeks 1, 2, 4, 6, 8, 10, 12 (end of treatment for 12-week treatment arms), and 16 (end of treatment for 16-week treatment arm) or premature discontinuation from treatment)
- Percentage of Participants With Sustained Virologic Response 4 Weeks Post-treatment (SVR4)(4 weeks after the last actual dose of study drug)
- Percentage of Participants With Post-treatment Relapse(From the end of treatment through 12 weeks after the last dose of study drug)
