NCT05283915

CompletedPhase 1

Sponsor: Sanofi

Conditions: Hepatic Function Abnormal

Interventions: tolebrutinib

Countries: United States

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.
