Study Endpoints
Primary Endpoints
Relative bioavailability as assessed by rilzabrutinib Cmax following administration of the test and reference formulations in the fasted state
Day 1 to Day 8

Cmax: maximum plasma concentration

Relative bioavailability as assessed by rilzabrutinib AUClast following administration of the test and reference formulations in the fasted state
Day 1 to Day 8

AUClast: area under the plasma concentration versus time curve from time zero to the last measurable concentration

Relative bioavailability as assessed by rilzabrutinib AUC following administration of the test and reference formulations in the fasted state
Day 1 to Day 8

AUC: area under the plasma concentration versus time curve extrapolated to infinity

Secondary Endpoints
