Brief Summary

The purpose of this study is to evaluate the dose-related safety, tolerability, pharmacokinetics (PK) and pharmacological effects (PD) of CORT125329 after single and multiple ascending oral doses of CORT125329 lipid capsule formulations in healthy participants.

Detailed Description

This is a 3-part, single-center study of single and multiple ascending doses of CORT125329 in healthy participants.

Part 1 will be a double-blind, randomized, placebo-controlled assessment of single ascending doses (SAD) of CORT125329 lipid capsule formulations. Participants will be enrolled sequentially into 1 of up to 8 cohorts, each containing 8 participants.

Part 2 will be double-blind, randomized, placebo-controlled assessments of multiple oral ascending doses (MAD) of CORT125329 lipid capsule formulations. Participants will be enrolled sequentially into 1 of up to 4 cohorts, each containing 8 participants.

Optional Part 3 will be an open-label, 2-way fixed sequence cross-over study and will serve as proof of PD (glucocorticoid receptor modulation) for CORT125329 lipid capsule formulations. Participants will be enrolled in a single cohort of 10 participants.

Throughout the study, routine safety tests will be performed. In selected parts of the study, assessments of PK (CORT125329), changes in serum cortisol and plasma adrenocorticotrophic hormone (ACTH), and changes in hematological and bone biomarkers will be measured.

Study Groups

SAD Cohort A CORT125329

Participants will receive a single dose of CORT125329 30 mg lipid capsule formulation 1 in the fasted state on Day 1

Group Type: EXPERIMENTAL

Intervention Type: DRUG

CORT125329 lipid capsule formulation 1 or 2 for oral administration

SAD Cohort B CORT125329

Participants will receive a single dose of CORT125329 lipid capsule formulation 1 in the fasted state on Day 1. The dose will be determined after review of safety, tolerability, and PK data from SAD Cohort A.

Group Type: EXPERIMENTAL

SAD Cohorts C through H CORT125329

Participants will receive a single dose of CORT125329 lipid capsule formulation 1 or 2 in the fasted or fed state on Day 1 in a dose escalation format. The dose, formulation, and prandial state for each cohort will be determined after review of safety, tolerability, and PK data from previous cohorts.

SAD Cohorts A through H Placebo

Participants will receive a single dose of placebo matching CORT125329 lipid capsule formulation 1 or 2 in the fasted or fed state on Day 1 in a dose escalation format. The dose, formulation, and prandial state for each placebo cohort will match that used in the corresponding CORT125329 cohort.

MAD Cohorts A through D CORT125329

Participants will receive CORT125329 lipid capsule formulation 1 or 2 in the fasted or fed state on Days 1 through 14 in a dose escalation format. The dose, dose frequency (once- or twice-daily), formulation, and prandial state for each cohort will be determined after review of safety, tolerability, and PK data from previous cohorts.

Pharmacodynamic (PD) Effect Cohort

Participants will receive a single dose of prednisone 25 mg in the fasted or fed state on Day 1 of Period 1. The prandial state for the Period 1 treatment will be determined after review of safety and tolerability data from the SAD Cohorts. After a 7-day washout period, participants will receive a single dose of prednisone 25 mg and a single dose of CORT125329 lipid capsule formulation 1 or 2 in the fasted or fed state on Day 1 of Period 2. The formulation and dose level of CORT125329 treatment in Period 2 will be determined after review of safety, tolerability, and PK data from the SAD cohorts. The prandial state for treatment in Period 2 will be the same used in Period 1.
