Summary

This study is being done to evaluate the efficacy and safety of the drug combination grazoprevir (GZR; MK-5172) + elbasvir (EBR; MK-8742) in participants with chronic hepatitis C virus (HCV) genotype (GT) 1, 4, or 6 infection and who have cirrhosis and Child-Pugh (CP) score 7-9 moderate hepatic insufficiency (CP-B). The primary hypothesis is that the percentage of HCV-infected participants with hepatic insufficiency (the CP-B population) achieving sustained viral response (SVR) 12 weeks after the end of all treatment (SVR12) will be greater than 60%. Additionally, ten non-cirrhotic (NC) HCV-infected GT1 participants will also be given GZR + EBR at the beginning of the study; this will be done for the purpose of collecting plasma pharmacokinetic (PK) data in HCV GT1-infected participants who do not have hepatic insufficiency.
