This is an open-label study being conducted in healthy adults, to learn what happens to the study medicine (camlipixant) they are receiving in a person's body over time (a pharmacokinetic \[PK\] study). The goal of the study is to understand how the body processes camlipixant, to check its safety and how well it is tolerated. Participants will receive camlipixant at different dose levels with different formulation types either on an empty stomach or after a meal.
