Clinical Trial Summary

The primary objective of this study is to evaluate the pharmacokinetics (PK) of miricorilant in the presence and absence of the strong cytochrome P450 [(CYP) 2C19] inhibitor, fluvoxamine, in healthy participants. Participants will receive a single dose of miricorilant under fed conditions with a standard breakfast after an overnight fast alone and in combination with once-daily doses of fluvoxamine. Blood samples will be collected at regular intervals for PK and safety analysis between admission and discharge from the clinical unit.
