This study is designed to determine the hypothalamic-pituitary-adrenal (HPA) axis suppression potential and pharmacokinetic (PK) properties of CB-03-01 Cream, 1%, applied every twelve hours for two weeks, in subjects with acne vulgaris ages 12 years or older.
729 studies on the registry are indexed under Acne Vulgaris; 85 are open to participants now.
This study's enrollment of 42 is below the median of 68 across 627 interventional studies indexed under Acne Vulgaris.

Exclusion Criteria:
Topical cream, 1.0% concentration, applied every twelve hours
Drug: cortexolone 17α-propionate
Also known as: CB-03-01, clascoterone (USAN, INN)
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.
Time frame: Baseline and Day 14
PK Profiles (Cmax) of Cortexolone 17α-propionate
Max concentration (Cmax) of cortexolone 17α-propionate in plasma following the first application (i.e., Day 1, 0-12 hours) and last application (i.e., Day 14, 0-12 hours).
Time frame: Baseline and Day 14
PK Profiles (AUC) of Cortexolone 17α-propionate
Area under the plasma concentration curve (0-12 hours) of cortexolone 17α-propionate at baseline (i.e., Day 1, after first application \[0-12 hours\]) and at Day 14 (i.e., Day 14, after last application \[0-12 hours\]).
Time frame: Baseline and Day 14
PK Profiles (Cavg) of Cortexolone 17α-propionate
Average concentration of cortexolone 17α-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).
