About this trial

This is an interventional treatment trial for Acne Vulgaris focused on measuring acne, cortexolone, anti-androgen

Eligibility Criteria

9 Years - 11 Years (Child)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patient must provide written informed assent and be accompanied by the parent or legal guardian at the time of assent/consent signing. The parent or legal guardian must provide written informed consent for the patient.
  • Patient has moderate to severe facial acne vulgaris as determined by the Investigator and obvious acne on the trunk (i.e., shoulders, upper chest, and/or back).
  • Females of childbearing potential must be using highly effective birth control methods with a negative urine pregnancy test (UPT) at study start.
  • Patient must be in general good health with normal renal function and no clinically relevant abnormalities present at study start.
  • Patient and parent/guardian are able to communicate with the staff and are willing to comply with study instructions, reside at and/or return to the clinic for required visits.

Exclusion Criteria:

  • Patient is pregnant, lactating, or is planning to become pregnant during the study.
  • Patient has a Body Mass Index (BMI) for age percentile > 95%.
  • Patient has any skin or medical condition, including facial hair that could interfere with the evaluation of the test article or requires the use of interfering topical or systemic therapy.
  • Patient has received an investigational drug or been treated with an investigational device within 30 days prior to study start.
  • Patient is currently enrolled in an investigational drug or device study.
  • Patient has any condition which, in the investigator's opinion, would make it unsafe for the patient to participate in this research study.
  • Patient has known allergy or sensitivity to CB-03-01 or any of its ingredients
  • Patient has participated in a previous CB-03-01 study.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

CB-03-01 cream, 1%

Arm Description

Topical CB-03-01 (cortexolone 17α-propionate) cream containing 1% active drug applied to the face and trunk twice daily for 14 days

Outcomes

Primary Outcome Measures

Change in HPA Axis Response as Measured by CST
Measurement of serum cortisol concentrations after stimulation of the adrenal cortex with cosyntropin (Cosyntropin Stimulation Test - CST). HPA axis suppression is defined as a post-stimulation serum cortisol level ≤ 18 μg/dL at Day 14.

Secondary Outcome Measures

Evaluate Trough Plasma Concentrations
Trough (single blood draw approximately 12 hours post the most recent dose) measurements of cortexolone 17α-propionate (clascoterone) concentration in plasma at Screening, Baseline, Day 7 and Day 14.

5. Study Description

Brief Summary
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 pediatric patients 9 to less than 12 years of age with acne vulgaris. Adrenal suppression effects and systemic safety are an important safety concern. The current study is designed to investigate these potential concerns under maximal use conditions.
