Inclusion Criteria
  • Cohorts 1 and 3: Participants with Mild or Moderate Hepatic Impairment

    • Participants will satisfy the criteria for mild (Cohort 1) and moderate hepatic impairment (Cohort 3) defined as a Child-Pugh total score of 5 to 6 and 7 to 9 points, respectively at the screening visit
    • Participants will have chronic (greater than or equal to (≥) 6 months) documented liver disease
  • Cohorts 2 and 4: Matched Healthy Participants

    • Participants will be matched (cohort 2 matched to cohort 1; and cohort 4 matched to cohort 3) during screening to participants with hepatic impairment for age, sex, and weight

    • History or presence of severe hepatic encephalopathy (Grade >2)
    • Any condition possibly affecting drug absorption
    • Significant renal dysfunction (creatinine clearance <60 milliliter per minute [mL/min] ) estimated according to the method of Cockcroft and Gault at the screening Visit or Day-1
    • History of solid organ or bone marrow transplantation
  • Cohorts 2 and 4: Matched Healthy Participants

    • History of febrile illness or other acute illness that has not fully resolved by 14 days before the first dose of study drug
