Study Summary

The purpose of the study is to investigate the effect of multiple doses of a proton-pump inhibitor (PPI) esomeprazole on the PK of vepdegestrant under fed conditions in healthy adult participants. All participants in this study will receive one dose of vepdegestrant alone by mouth in Period 1. In Period 2, everyone will receive esomeprazole by mouth once a day for multiple days. Participants will also receive one dose of vepdegestrant by mouth. The levels of vepdegestrant in Period 1 will be compared to the levels of vepdegestrant in Period 2 to determine if the PPI affects how vepdegestrant is processed differently in healthy adults.
