Conditions
Summary
The main purpose of this study is to measure how food affects the amount of tersolisib that gets into the bloodstream. Each participant will receive two single oral doses of tersolisib, one under fasted conditions and one with either a high-fat or a low-fat meal. Blood tests will be performed to investigate how the body processes the study drug under each condition. For each participant, the study will last about 9 weeks and will include a stay in the Clinical Research Unit (CRU) lasting almost a month.
