This is an open-label, randomized, 3 treatment, 3-period, 6-sequence, crossover study. Eligible subjects will participate in 3 treatment periods. During each treatment period, subjects will receive a single 300-mg relacorilant dose. An equal number of subjects will be randomized to each of 6 sequences (i.e., ABC, BCA, CAB, BAC, ACB, and CBA):~(A) relacorilant single 300 mg dose (3×100-mg softgel capsules) following a minimum 10 hour fast (Test 1) (B) relacorilant single 300 mg dose (3×100-mg hard-shell capsules) following a minimum 10-hour fast (Test 2) (C) relacorilant single 300 mg dose (6×50-mg hard-shell capsules) following a minimum 10 hour fast (Reference) Subjects will be admitted to the Clinical Research Unit (CRU) on the morning of Day -1 of each period following an 8-hour fast for baseline assessments and will remain confined until Day 3 of each period. After dosing in Period 1 and Period 2, subjects will undergo minimum 14 day washouts between doses of study drug. Subjects will then receive the next relacorilant dose in their randomized sequence in Period 2 and Period 3, respectively. Subjects will attend an outpatient Follow-up Visit 14±2 days after the last dose of study drug in Period 3 (or Early Termination Visit).~Blood samples will be collected before dosing and at intervals up to 120 hours after relacorilant dose in Periods 1, 2 and 3.~Safety and tolerability will be monitored using AEs, clinical laboratory evaluations, 12-lead ECG recordings, vital signs, and physical examinations.
This is an open-label, randomized, 3 treatment, 3-period, 6-sequence, crossover study conducted at a single study center to characterize the relative bioavailability of relacorilant administered as 3×100-mg softgel capsules (Treatment A), 3×100 mg hard-shell capsules (Treatment B), and 6×50-mg hard shell capsules (Treatment C/reference) in healthy, fasted, adult subjects.~Eligible subjects will participate in 3 treatment periods. During each treatment period, subjects will receive a single 300-mg relacorilant dose. An equal number of subjects will be randomized to each of 6 sequences.
