Effect of Hepatic Impairment on M2951 (BTK Inhibitor) PK

Study Overview
=================
Brief Summary
-----------------
This study is to investigate the pharmacokinetic (PK) and safety of M2951 (Bruton's tyrosine kinase [BTK] inhibitor) in participants with different degrees of hepatic impairment compared to participants with normal hepatic function.

Official Title

Conditions
-----------------
Hepatic Impairment

Intervention / Treatment
-----------------
* Drug: M2951 (BTK inhibitor)


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Participants with normal hepatic function only will be overtly healthy as determined by medical evaluation, including no clinically significant abnormality identified on physical examination or laboratory evaluation and no active clinically significant disorder, condition, infection or disease that would pose a risk to participant safety or interfere with the study evaluation, procedures, or completion OR Participants with moderately impaired hepatic function only will be considered to have moderately (Child-Pugh class B and confirmed liver cirrhosis) impaired hepatic function and has been clinically stable for at least 1 month prior to Screening OR Participants with mildly impaired hepatic function only will be considered to have mildly (Child-Pugh class A and confirmed liver cirrhosis) impaired hepatic function and has been clinically stable for at least 1 month prior to Screening Have a body weight within 50.0 and 120.0 kilogram (kg) and body mass index (BMI) within the range 19.0 and 36.0 kilogram per square meter (kg/m^2) Female participants are not pregnant or breastfeeding, and at least one of the following conditions applies Not a woman of childbearing potential (WOCBP) Other protocol defined inclusion criteria could apply Exclusion Criteria: Clinical history of autoimmune disorder with hepatic influence (Hashimoto thyroiditis and rheumatic diseases allowed) History of any malignancy Diseases and surgeries of the gastrointestinal tract, which could influence the gastrointestinal anatomy and mobility. Prior history of cholecystectomy or inflammatory bowel disease, and any clinically relevant surgery within 6 months prior to Screening History of chronic or recurrent acute infection or any bacterial, viral, parasitic or fungal infections within 30 days prior to Screening and at any time between Screening and admission, or hospitalization due to infection within 6 months prior to Screening History of shingles within 12 months prior to Screening History of drug hypersensitivity, ascertained or presumptive allergy/hypersensitivity to the active drug substance and/or formulation ingredients; history of serious allergic reactions leading to hospitalization or any other hypersensitivity reaction in general, which may affect the safety of the participant and/or outcome of the trial per the Investigator's discretion Participants with impaired hepatic function will be excluded who had Primary and secondary biliary cirrhosis. Participants with impaired hepatic function will be excluded with Clinical evidence of severe ascites. Participants with impaired hepatic function will be excluded with Hepatic encephalopathy Grade greater than 1 Other protocol defined exclusion criteria could apply
