Effect of Hepatic Impairment on M2951 (BTK Inhibitor) PK
Study Details
Study Description
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.
