Brief summary

Primary Objective: * To evaluate the impact of food on the pharmacokinetics (PK) of rilzabrutinib following single oral doses to healthy subjects. * To evaluate the impact of formulation on the PK of rilzabrutinib following single oral doses to healthy subjects Secondary Objective: \- To assess the safety and tolerability of single oral doses of rilzabrutinib administered under fasted and fed conditions

Detailed description

The total study duration is approximately 43 days for each participant, including a screening period of 2 to 28 days, treatment period of 12 days, and follow-up of 3 days
