Overview

The main purpose of this study is to evaluate how a medicine, LY3841136, works in participants with different levels of liver damage and in participants with healthy liver. The researchers want to see how the medicine is absorbed and used by the body, and if it causes any side effects, in participants with mild, moderate, or severe liver damage, as well as in participants with normal liver function.

For each participant, the study will last about 14 weeks, which will include a stay at the clinical research unit for 5 nights.

Eligibility

Inclusion Criteria:

• Have a body weight of 55 kilograms (kg) or more and body mass index between 19.0 and 40.0 kilograms per square meter (kg/m²), inclusive

Group 1

Groups 2 through 4

• Have hepatic impairment classified as Child-Pugh score A, B, or C (mild, moderate, or severe impairment who are considered acceptable for participation in this study by the investigator. Participants must have a diagnosis of chronic hepatic impairment of greater than 6 months per physician diagnosis and standard-of-care practice, with no clinically significant changes in the opinion of the investigator within 15 days prior to screening

Participants with hepatic impairment may have stable baseline medical conditions for which neither the condition nor treatments received would negatively impact the health of the participant or study conduct

Exclusion Criteria:

• Have a current infection with hepatitis B virus (HBV), that is,
  • if hepatitis B surface antigen (HBsAg) is positive, the participant is excluded, or
  • if HBsAg is negative and anti-Hepatitis B core antibody (HBc) is positive, further testing for HBV deoxyribonucleic acid (DNA) is required, and
    • if the screening HBV DNA is positive, the participant is excluded
• Have a current infection with hepatitis C virus (HCV), that is,
  • if anti-HCV is positive, a test for circulating HCV ribonucleic acid (RNA) is required, and
