Inclusion criteria

* Screening laboratory result indicating hepatitis C virus (HCV) Genotype 1, 2, 4, 5 or 6 (GT1,2,4,5,6) infection * Chronic HCV infection * Subject must be HCV treatment-naïve or have failed prior HCV treatment * Subject must have documented compensated cirrhosis and no current or past clinical evidence of decompensated liver disease

Exclusion criteria

* Positive test result at screening for Hepatitis B surface antigen or anti-human immunodeficiency virus (anti-HIV) antibody * HCV genotype performed during screening indicating co-infection with more than 1 HCV genotype * Consideration by the investigator, for any reason, that the subject is an unsuitable candidate to receive ABT-493/ABT-530

Percentage of Participants With On-treatment Virologic FailureTreatment Weeks 1, 2, 4, 8, and 12 (end of treatment) or premature discontinuation from treatmentOn-treatment virologic failure was defined as confirmed increase of \> 1 log(subscript)10(subscript) IU/mL above the lowest value post-baseline HCV RNA during treatment; confirmed HCV RNA ≥ 100 IU/mL after HCV RNA \< LLOQ during treatment, or HCV RNA ≥ LLOQ at end of treatment with at least 6 weeks of treatment.
Percentage of Participants With Post-treatment RelapseFrom the end of treatment through 12 weeks after the last dose of study drugPost-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 who completed treatment with HCV RNA levels \< LLOQ at the end of treatment, excluding reinfection.

Outcome results

Primary

Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)

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.

Time frame: 12 weeks after the last actual dose of study drug

Population: Intent-to-treat (ITT) population: all participants who received at least 1 dose of study drug; participants with missing data after backwards imputation were imputed as nonresponders.

Secondary

Percentage of Participants With On-treatment Virologic Failure

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

Time frame: Treatment Weeks 1, 2, 4, 8, and 12 (end of treatment) or premature discontinuation from treatment

Population: All participants who received at least 1 dose of study drug (ITT population).

Percentage of Participants With Post-treatment Relapse

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 who completed treatment with HCV RNA levels \< LLOQ at the end of treatment, excluding reinfection.

Time frame: From the end of treatment through 12 weeks after the last dose of study drug

Population: All participants who received at least 1 dose of study drug, completed treatment, and had HCV RNA \<LLOQ at the final treatment visit.
