End point title |
Change in HPA Axis Response to Cosyntropin [1] | ||||||||||||||||||||||||
End point description |
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.

Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: All analyses were descriptive. Serum cortisol results were summarized for evaluable subjects. HPA axis responses to CST were dichotomized to normal and abnormal. |

Adverse event reporting additional description |
Any treatment emergent AEs ongoing at the end of the treatment period (Day 14) were followed until they resolve, the condition stabilizes, the events are otherwise explained, or the subject is lost to follow-up. In addition, all SAEs were followed until resolution as previously stated for study product-related AEs.
