A Study to Evaluate the Effect of Mild and Moderate Hepatic Impairment on the Single-Dose Pharmacokinetics of Rilzabrutinib (PRN1008)

An Open-Label, Phase 1 Study to Evaluate the Effect of Mild and Moderate Hepatic Impairment on the Single-Dose Pharmacokinetics of Rilzabrutinib (PRN1008)

This is a single-dose study to assess the effect of mild or moderate Hepatic Impairment (HI) on the Pharmacokinetics (PK) of rilzabrutinib as well as to evaluate the safety and tolerability of rilzabrutinib in subjects with HI.

Inclusion Criteria:
