Brief summary
The purpose of this study is to assess the safety and efficacy of ABT-493/ABT-530 following 12 weeks of treatment in adults with chronic Hepatitis C Virus Infection genotype 1, 2, 4, 5 or 6 infection and compensated cirrhosis.
Interventions
Tablet; ABT-493 coformulated with ABT-530

Eligibility
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

Outcome results
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.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| ABT-493/ABT-530 | Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12) | 99.3 percentage of participants |
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).
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| ABT-493/ABT-530 | Percentage of Participants With On-treatment Virologic Failure | 0.0 percentage of participants |
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.
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| ABT-493/ABT-530 | Percentage of Participants With Post-treatment Relapse | 0.7 percentage of participants |
