Outcomes
Primary Outcomes
Ratio From Baseline of the Serum Cortisol Weighted Mean (0-24 Hours) on Day -1/1 (Baseline) and Day 42
Time Frame: Day -1/1 (Baseline) and Day 42
Serum cortisol weighted mean was determined for each participant over the time period 0-12 hours on Day -1/1 (Baseline) and Day 42. Serum cortisol weighted mean was derived by dividing the area under the concentration-time curve (AUC; defined as thearea under the concentration-time curve from time zero up to 24 hours) by the sample collection time interval. The sample collection time interval is defined as the difference between the time of the last cortisol sample and the time of the first cortisol sample. Samples were collected at the following time points: 0 (first blood draw/pre-dose); 2, 4, 9, 12, 14, 16, 20, 22, and 24 hours (relative to the "0" time point). Because values are on a logged scale, the ratio of the endpoint to Baseline is presented, as it is a measure of the difference from Baseline.
