Brief summary
A study designed to characterize the plasma pharmacokinetic (PK) profile of CORT125134 in healthy subjects receiving once-daily oral administration of the current capsule formulation of CORT125134 for 14 days.
Detailed description
Initially, subjects will be enrolled into 2 cohorts each of 8 subjects (Cohort 1 and Cohort 2) to receive CORT125134 at 150 mg or 250 mg, respectively. Data from Cohorts 1 and 2 will be evaluated to select dose levels for Cohort 3 and optional Cohort 4. The secondary objective of the study is to characterize the plasma PK profile of CORT125134 metabolites in healthy subjects receiving once-daily oral administration of the current capsule formulation of CORT125134.
