The purpose of this study is to test a new medicine called Inno8. The study will test how eating and drinking before and after taking Inno8 affects how well it is absorbed in the stomach. The study consists of four arms. Participants will take the study medicine after an overnight fast. How long participants will need to fast depends on which group participants are in. After taking the study medicine, participants will need to fast again. The study will last for up to 9.5 weeks.
