Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in HPA Axis Response to Cosyntropin	Measurement of serum cortisol concentrations after stimulation of the adrenal cortex with cosyntropin injection (Cosyntropin Stimulation Test - CST). Prior to CST, a pre-CST blood sample is taken between 7AM to 9AM. Thirty minutes after CST, a post-CST blood sample is collected. HPA axis suppression is defined as a post-stimulation serum cortisol level = 18 µg/dL at Day 14.	Baseline and Day 14
Primary	PK Profiles (Cmax) of Cortexolone 17a-propionate	Max concentration (Cmax) of cortexolone 17a-propionate in plasma following the first application (i.e., Day 1, 0-12 hours) and last application (i.e., Day 14, 0-12 hours).	Baseline and Day 14
Primary	PK Profiles (AUC) of Cortexolone 17a-propionate	Area under the plasma concentration curve (0-12 hours) of cortexolone 17a-propionate at baseline (i.e., Day 1, after first application [0-12 hours]) and at Day 14 (i.e., Day 14, after last application [0-12 hours]).	Baseline and Day 14
Primary	PK Profiles (Cavg) of Cortexolone 17a-propionate	Average concentration of cortexolone 17a-propionate in plasma calculated as the ratio of the AUC(0-12 hours) and the dosing interval (i.e., 12 hours) at baseline (i.e., Day 1, after first application) and at Day 14 (after last application).	Baseline and Day 14
