Brief summary
This study will evaluate the efficacy and safety of glecaprevir/pibrentasvir (ABT-493/ABT-530) in chronic hepatitis C virus (HCV) genotype (GT)1 to GT6-infected Asian participants with compensated cirrhosis with or without human immunodeficiency virus (HIV) co-infection who are HCV treatment-naïve or treatment-experienced with interferon (IFN) (alpha, beta or pegylated interferon \[pegIFN\]) with or without ribavirin (RBV) OR sofosbuvir with RBV with or without IFN.

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; 15 IU/mL) 12 weeks after the last dose of study drug.
Time frame: 12 weeks after the last actual dose of study drug, Week 24 or Week 28 depending on the treatment regimen.
Population: All enrolled participants who received at least 1 dose of study drug. Backward imputation, where applicable, was used to impute missing data. Participants with missing data after backward imputation were counted as non-responders.
