A study in healthy volunteers to find out how long aticaprant stays in and acts on the body when administered with or without food and with or without fluconazole

This study is about a new medicine called aticaprant. We're asking healthy volunteers to join because we need to understand how this medicine works inside the human body. Think of it like learning how a new car engine runs — we need to see how efficiently it uses fuel, how long it can run, and if certain conditions (like adding special fuel or driving uphill) change how it performs.

Specifically, researchers want to see how long it takes for aticaprant to get into your system, how long it stays active there, and how your body eventually gets rid of it. This is really important information because it helps doctors figure out the right dose to give patients and how often they should take the medicine. They also want to see if eating food at the same time as taking aticaprant changes how your body handles the medicine. This is common with many medicines, where food can speed up, slow down, or even stop the medicine from working as well.

Finally, the study will also look at whether a common anti-fungal medicine called fluconazole, which many people take for infections, affects how aticaprant behaves in the body. Sometimes, taking two medicines at once can change how each one works. By understanding these things early on, researchers can make sure that when aticaprant is eventually given to patients who need it, it will be as safe and effective as possible.
