Trial Outcomes & Findings for An Evaluation of the Adrenal Suppression Potential and Pharmacokinetic Properties of CB-03-01 Cream in Subjects With Acne Vulgaris (NCT NCT01831960)

NCT ID: NCT01831960

Last Updated: 2020-12-02

Results Overview

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.
