Part 2: CORT113176 (Dazucorilant) 75 - 300 mg Dose-titrationEXPERIMENTAL75 mg of dazucorilant will be administered once daily for 1 week, and increased weekly in 75 mg increments up to 300 mg once daily.
Moderate Hepatic ImpairmentEXPERIMENTALOn Day 1, each participant with moderate hepatic impairment will receive a single oral dose of dazucorilant 300 mg.
Matched Healthy ParticipantsEXPERIMENTALHealthy participants will be matched to those with moderate hepatic impairment as to gender, age (± 10 years of the mean), and weight (± 20% of the mean). On Day 1, each healthy participant will receive a single oral dose of dazucorilant 300 mg.
Mild Hepatic ImpairmentEXPERIMENTALOn Day 1, each participant with mild hepatic impairment will receive a single oral dose of dazucorilant 300 mg. This arm may be enrolled after review of interim PK evaluation of the effects of moderate hepatic impairment.
Dazucorilant (300 mg) and itraconazole (200 mg)EXPERIMENTALOn Days 1 and 8, each participant will receive a single oral dose of dazucorilant 300 mg, in a fed state. On Days 5-11, all participants will be administered once daily, oral doses of itraconazole 200 mg, in a fed state.
