A Study to Assess Change in How Oral Icalcaprant With Itraconazole Moves Through the Body in Healthy Adult Participants

A Phase 1 Open-label Study to Evaluate the Effect of Itraconazole on the Pharmacokinetics of Icalcaprant in Healthy Adult Subjects

This study is to assess the change of itraconazole, a strong CYP3A inhibitor, on the pharmacokinetics, safety, and tolerability of a single dose of icalcaprant in healthy participants.

Inclusion Criteria:

• Body Mass Index (BMI) is ≥ 18.0 to ≤ 32.0 kg/m^2 after rounding to the tenths decimal. BMI is calculated as weight in kg divided by the square of height measured in meters.
• A condition of general good health, based upon the results of a medical history, physical examination, vital signs, laboratory profile and a 12-lead ECG.

Exclusion Criteria:

• History of any clinically significant sensitivity or allergy to any medication or food.
• Exposure to icalcaprant within the past 90 days.
• History of or active medical condition(s) or surgical procedure(s) that might affect gastrointestinal motility, pH, or absorption [e.g., Crohn's disease, celiac disease, gastroparesis, short bowel syndrome, gastric surgery (except pyloromyotomy for pyloric stenosis during infancy), cholecystectomy, vagotomy, bowel resection, etc.].
