          -  Participant has any liver disease of non-HCV etiology. This includes, but is not
             limited to, acute hepatitis A, drug- or alcohol-related liver disease, autoimmune

             non-alcoholic steatohepatitis, primary biliary cirrhosis, or any other non-HCV liver
             disease considered clinically significant by the investigator

          -  Participant is infected/co-infected with non-genotype 4 HCV

          -  Participant has any other active clinically significant disease or clinically
             significant findings during screening of medical history, physical examination,
             laboratory testing or electrocardiogram (ECG) recordings that, in the investigator's
             opinion, would compromise the participant's safety or could interfere with the
             participant participating in and completing the study

          -  Participant has history of malignancy within 5 years of the screening visit
             (exceptions: skin carcinomas, carcinoma in situ of the cervix, or malignancy that in
