Study to Evaluate the Effects of a Cytochrome P450 2C19 Inhibitor on the Pharmacokinetics of Miricorilant
Phase 1
Completed
- Conditions
- Non-alcoholic Steatohepatitis (NASH)Antipsychotic Induced Weight Gain
- Interventions
- Registration Number
- NCT05712265
- Lead Sponsor
- Corcept Therapeutics
- Brief 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.
