Inclusion Criteria
  • Hepatic Impaired Subjects:

    • Non-smoking or light smoker (not exceeding 5 cigarettes per day), adult male or non-pregnant, non-lactating female, 18-75 years of age, inclusive, at screening.
    • Weight ≥ 50 kg, at screening.
  • Healthy Subjects:

    • Non-smoking or light smoker (not exceeding 5 cigarettes per day), healthy, adult males and non-pregnant, non-lactating females, 18-75 years of age, inclusive, at screening.

Subject must be matched for age (within ± 10 years), and sex of the matched subject with hepatic impairment.

--Weight ≥ 50 kg at screening.

Additional inclusion criteria might apply.

Exclusion Criteria
  • Hepatic Impaired Subjects:

    • Pregnant or lactating female.
    • Uncontrolled treated/untreated hypertension (systolic blood pressure ≥ 160 millimeters of mercury [mmHg] and/or diastolic blood pressure ≥ 105 mmHg), or resting pulse rate < 45 or > 100 beats per minute (bpm). Measurements may be repeated once in order to determine eligibility.
  • Healthy Subjects

Primary Outcome Measures
NameTimeMethod
Area under the concentration-time curve of total rilzabrutinib in plasma over the time interval from 0 extrapolated to infinity (AUC0-inf)Up to 30 hours after rilzabrutinib dosing
Time from dosing to maximum measured concentration of total rilzabrutinib in plasma (tmax)Up to 30 hours after rilzabrutinib dosing
Terminal Half-Life of total rilzabrutinib in Plasma (t1/2)Up to 30 hours after rilzabrutinib dosing
Apparent Total Clearance of rilzabrutinib in the plasma after extra-vascular administration (CL/F)Up to 30 hours after rilzabrutinib dosing
Fraction of unbound drug ( rilzabrutinib) expressed as percent (%fu)Up to 24 hours after rilzabrutinib dosing
Area under the concentration-time curve of total rilzabrutinib in plasma from 0 to t (AUC0-t)Up to 30 hours after rilzabrutinib dosing
Apparent Volume of Distribution during the Terminal elimination phase after extravascular administration (Vz/F)Up to 30 hours after rilzabrutinib dosing
Number of Adverse Events (AE) / Serious Adverse Events (SAE)From date of signed ICF, up to 9 days after rilzabrutinib dosing
Incidence of potentially clinically significant laboratory test, vital signs, and electrocardiogram (ECGs) abnormalitiesUp to 30 hours after rilzabrutinib dosing
Percent of AUC0-inf extrapolated total rilzabrutinib in plasma (%AUCextrap )Up to 30 hours after rilzabrutinib dosing
Maximum measured concentration of total rilzabrutinib in plasma (Cmax)Up to 30 hours after rilzabrutinib dosing

Secondary Outcome Measures
NameTimeMethod
Maximum measured concentration of rilzabrutinib metabolites in plasma (Cmax)Up to 24 hours after rilzabrutinib dosing
Time from dosing to maximum measured concentration of rilzabrutinib metabolites in plasma (tmax)Up to 24 hours after rilzabrutinib dosing
Terminal Half-Life of rilzabrutinib metabolites in Plasma (t1/2)Up to 24 hours after rilzabrutinib dosing
Elimination Rate Constant of rilzabrutinib metabolites (Kel)Up to 24 hours after rilzabrutinib dosing
Metabolite-to-parent ratio (MRAUC)Up to 24 hours after rilzabrutinib dosing

MRAUC is Based on AUC0-t, corrected for Molecular weights (MW). MRAUC = (AUC0-t,M/AUC0-t,P) x (MW,P/MW,M) where M was metabolite and P was parent.

Metabolite-to-parent ratio (MRCmax)Up to 24 hours after rilzabrutinib dosing

MRCmax is based on Cmax, corrected for MW. MRCmax = (Cmax,M/ Cmax,P) x (MW,P/MW,M) where M was metabolite and P was parent.

Area under the concentration-time curve of rilzabrutinib metabolites in plasma from 0 to t (AUC0-t)Up to 24 hours after rilzabrutinib dosing
Area under the concentration-time curve of rilzabrutinib metabolites in plasma over the time interval from 0 extrapolated to infinity (AUC0-inf)Up to 24 hours after rilzabrutinib dosing
Percent of AUC0-inf extrapolated rilzabrutinib metabolites in plasma (%AUCextrap)Up to 24 hours after rilzabrutinib dosing
