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.

Arm AABT-493, ABT-530ABT-493 (200 mg) once daily (QD) co-administered with ABT-530 (80 mg) QD for 12 weeks in chronic HCV genotype 1- infected participants without cirrhosis.
Arm BABT-493, ABT-530ABT-493 (300 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD plus ribavirin (RBV) for 12 weeks in chronic HCV genotype 1- infected participants without cirrhosis.
Arm Bribavirin (RBV)ABT-493 (300 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD plus ribavirin (RBV) for 12 weeks in chronic HCV genotype 1- infected participants without cirrhosis.
Arm CABT-493, ABT-530ABT-493 (300 mg) once daily (QD) co-administered with ABT-530 (120 mg) QD for 12 weeks in chronic HCV genotype 1- infected participants without cirrhosis.
Arm DABT-493/ABT-530ABT-493/ABT-530 (300 mg/120 mg) coformulated once daily (QD) for 12 weeks in HCV genotypes 1- or 4-6- infected participants with or without cirrhosis.
Arm EABT-493/ABT-530ABT-493/ABT-530 (300 mg/120 mg) coformulated once daily (QD) for 16 weeks in HCV genotype 1- or 4-6- infected participants with or without cirrhosis.
Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)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 Outcome Measures
NameTimeMethod
Percentage of Participants With On-treatment Virologic FailureDay 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

On-treatment virologic failure was defined as confirmed HCV RNA ≥ 100 IU after HCV RNA \< LLOQ during treatment; confirmed increase of \> 1 log(subscript)10(subscript) IU/mL above the lowest value post-baseline in HCV RNA during treatment; or HCV RNA ≥ LLOQ at end of treatment with at least 6 weeks of treatment.

Percentage of Participants With Sustained Virologic Response 4 Weeks Post-treatment (SVR4)4 weeks after the last actual dose of study drug

SVR4 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification \[\<LLOQ\]) 4 weeks after the last dose of study drug.

Percentage of Participants With Post-treatment RelapseFrom the end of treatment through 12 weeks after the last dose of study drug

Post-treatment relapse was defined as confirmed HCV RNA ≥ LLOQ between the end of treatment and 12 weeks after the last dose of study drug among participants with HCV RNA levels \< LLOQ at the end of treatment, excluding reinfection.
