Study to Assess the Plasma Concentration of Tolebrutinib Given as a Tablet to Adult Participants With Mild Hepatic Impairment Compared to Participants With Normal Hepatic Function

An Open-label Phase 1, Pharmacokinetic and Tolerability Study of Tolebrutinib Given as a Single Dose in Adult Participants With Mild Hepatic Impairment, and in Matched Participants With Normal Hepatic Function

The purpose of this parallel group, Phase 1, open-label, 2-arm, single dose, multi-center study is to assess the effect of mild hepatic impairment on pharmacokinetics (PK), safety and tolerability of tolebrutinib compared with normal hepatic function, in male and female participants aged 18 to 79 years.

Description

Inclusion Criteria:

For participants with mild hepatic impairment

• Stable chronic liver disease assessed by medical history, physical examination, and laboratory values
• Child-Pugh total score ranging from 5 to 6, inclusive.
• Laboratory parameters within the acceptable range for participants with hepatic impairment; however, estimated glomerular filtration rate (eGFR) should be above or equal to 60 mL/min
