Primary Outcome Measures
NameTimeMethod
Maximal Decrease From Baseline in log10 HCV RNA Levels During ABT-493 or ABT-530 Monotherapy TreatmentDay 1 through prior to first dose of the combination regimen on Study Day 4

Maximal decrease from baseline in log10 HCV RNA levels during ABT-493 or ABT-530 monotherapy treatment. The baseline value was the last measurement before the first dose of monotherapy on Day 1.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)12 weeks after last actual dose of combination 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 combination study drug.

Percentage of Participants With Post-treatment RelapseFrom the end of treatment through 12 weeks after the last dose of combination 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 completing combination treatment with HCV RNA levels \< LLOQ at the end of treatment.

Percentage of Participants With On-treatment Virologic FailureUp to 87 days

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