Healthy Participants
Conditions
Brief summary
This is a Phase 1, open-label, randomized, two-part study to evaluate the relative bioavailability (rBA) of two tablet formulations compared to the capsule formulation of ZN-A-1041 (Part 1). Part 2 of the study will evaluate the effect of food and rabeprazole on the ZN-A-1041 tablet formulation. No participants were enrolled in Part 2 of the study as it has been cancelled.
Interventions
Participants will be administered either a ZN-A-1041 capsule or a tablet orally.
