Study to Assess Drug Levels and Safety of BMS-986278 in Healthy Participants and Participants With Different Degrees of Hepatic Impairment

A Phase 1, Multi-center, Open-label Study to Assess the Pharmacokinetics and Safety of BMS-986278 in Healthy Participants and Those With Mild, Moderate and Severe Hepatic Impairment

The purpose of this study is to assess the drug levels and safety of BMS-986278 in participants with mild, moderate, and severe Hepatic Impairment (HI), and in matched healthy control participants with normal hepatic function.

Inclusion Criteria:

All Participants:

• Must have a body mass index (BMI) between 18 and 40 kg/m^2 (inclusive), and body weight ≥ 50 kg.

Mild, Moderate, or Severe Hepatic Impairment Participants:

• Mild, moderate, or severe hepatic impairment (HI) or cirrhosis due to chronic hepatic disease and/or prior alcohol use.
• Mild, moderate, and severe HI participants will be enrolled according to the Child-Pugh classification score.

Matched Healthy Participants:

• Free of any clinically significant disease that would interfere with the study evaluations.
• Normal hepatic function participants will be enrolled and matched individually with HI participants with respect to age (± 10 years), weight (± 20%), sex, and race/ethnicity (Japanese and Chinese participants vs non-Japanese and non-Chinese participants).

Exclusion Criteria:

All Participants:

• History of alcohol abuse within 1 year prior to screening or regular use of alcohol within 6 months prior to screening that exceeds 7 units for women, or 14 units for men of alcohol per week (1 unit = 340 mL of beer 5%, 140 mL of wine 12%, or 45 mL of distilled alcohol 40%).
• Must not have had any prior exposure to BMS-986278.

Mild, Moderate, or Severe Hepatic Impairment Participants:

• Acute liver disease (eg, caused by an acute infection or drug toxicity).
• History of initial stage/planned liver transplantation within 6 months of screening or has received a liver transplant.

Matched Healthy Participants:

• Any significant medical condition, or psychiatric illness that would prevent participant from participating in the study.
• Other protocol-defined inclusion/exclusion criteria apply.
