• Have non-clinically significant findings at physical examination and in clinically laboratory evaluations.
• Moderate hepatic impairment participants with nonalcoholic steatohepatitis (NASH) only should have a history or presence of metabolic syndrome or type 2 diabetes, clinical characteristics or prior liver biopsy, ALT ≥ 43 IU/L for men and ≥ 28 IU/L for women, and except for participants with prior liver biopsy, participants should have currently or previously one of the following: MRI-iron-corrected T1 (cT1) value > 800 ms, MRI proton density fat fraction (PDFF) liver fat content ≥ 8 % or FibroScan liver stiffness measurement (LSM) ≥ 8.5 kilopascals (kPa).

Exclusion Criteria:

• History of significant drug abuse within 1 year prior to screening or recreational use of soft drugs within 1 month or hard drugs within 3 months prior to screening, unless for hepatic impaired participants only, the participants uses any of these drugs as prescriptions.
• History of significant alcohol abuse within six months prior to screening or regular use of alcohol within six months prior to the screening visit.
• Donation of plasma within 7 days prior to dosing. Donation or loss of blood of 50 mL to 499 mL of blood within 30 days, or more than 499 mL within 56 days prior to the dosing.
• Female participants with a positive pregnancy test.
• Participant with a positive alcohol test at screening.
• History of allergic reactions to miricorilant or other related drugs
• Known clinically significant hypersensitivity to any of the ingredients or excipients of the study drug
• Previous participation in a study with miricorilant administration.
• Participated in a clinical research study involving the administration of an investigational or marketed drug or device within 30 days prior to dosing.
• Participants who have taken oral, parenteral, depot or intra-articular glucocorticoids within 12 months prior to study drug administration; or intranasal, topical, or inhaled glucocorticoids within 2 weeks prior to study drug administration.
• Male participants (including men who have had vasectomies) with a pregnant or lactating partner.
• Breast-feeding female participants
• Inability or difficulty to swallow tablets
• Inability to be venipunctured and/or tolerate catheter venous access.

Additional Exclusion Criteria for Healthy Group (No Hepatic Impairment) Participants Only:

• Any clinically significant abnormality at physical examination, clinically significant abnormal laboratory test results or positive test for HBsAg, HCV, or HIV at screening;
• Participants using medication other than topical products without significant systemic absorption.
