What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Ratio From Baseline of the Serum Cortisol Weighted Mean (0-24 Hours) on 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.	Day -1/1 (Baseline) and Day 42

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Ratio From Baseline of the Serum Cortisol Area Under the Concentration-time Curve (AUC) (0-24 Hour) on Day -1/1 (Baseline) and Day 42	Area under the plasma drug concentration-time (AUC[0-24 hour]) curve from time zero (pre-dose) to the last time of quantifiable serum cortisol concentration at 24 hours post-dose on Day -1/1 (Baseline) and Day 42 was measured. AUC reflects the actual body exposure to drug over a specified period of time after administration of a dose. Samples were collected at the following times: 0 (immediately pre-dose inhaled study drug); post-dose at 5 minutes (min), 15 min, 30 min, and 1 hour (hr), 2 hr, 4 hr, 9 hr, 12 hr, 16 hr, 20 hr, and 24 hr. 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.	Day -1/1 (Baseline) and Day 42
Ratio From Baseline of Serum Cortisol Trough (0-24 Hours) at Day -1/1 (Baseline) and Day 42	Serum cortisol trough is defined as the minimum value of serum cortisol measured over the 24-hour period. Samples were collected at the following times: 0 (immediately pre-dose inhaled study drug); post-dose at 5 minutes (min), 15 min, 30 min, and 1 hour (hr), 2 hr, 4 hr, 9 hr, 12 hr, 16 hr, 20 hr, and 24 hr. 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.	Day -1/1 (Baseline) and Day 42
Ratio From Baseline of 0-24 Hour Urinary Free Cortisol Excretion on Day -1/1 (Baseline) and Day 42	A 24-hour urine sample was collected for the measurement of 24-hour urinary cortisol excretion at Day -1/1 (Baseline) and Day 42. Only those participants available at the specified time points were analyzed. 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.	Day -1/1 (Baseline) and Day 42
Plasma FF and VI Pharmacokinetic (PK) Concentration	Plasma FF and VI Pharmacokinetic (PK) Concentration were estimates at the following time points:0 (immediately pre-dose inhaled study drug), and post-dose at 5 min, 15 min, 30 min, and 1 hr, 2 hr, 4 hr, 9 hr, 12 hr, 16 hr, 20 hr, 24 hr on Day 42. Only those participants available at the specified time points were analyzed (represented by n=X, X, X, X in the category titles). Different participants may have been analyzed at different time points, so the overall number of participants analyzed reflects everyone in the Pharmacokinetic Population.	Day 42
AUC(0-t) and AUC(0-24) for FF on Day 42	Area under the plasma drug concentration-time (AUC[0-t]) curve from time zero (pre-dose) to the last time of quantifiable FF concentration and AUC(0-24) is the concentration time curve from zero (pre-dose) to 24 hours of quantifiable FF concentration on Day 42 was measured. AUC reflects the actual body exposure to drug over a specified period of time after administration of a dose. Samples were collected at the following times: 0 (immediately pre-dose inhaled study drug); post-dose at 5 minutes (min), 15 min, 30 min, and 1 hour (hr), 2 hr, 4 hr, 9 hr, 12 hr, 16 hr, 20 hr, and 24 hr post-dose on Day 42.	Day 42
Cmax for FF on Day 42	Cmax is defined as the maximum observed concentration on Day 42. Samples were collected at the following times: 0 (immediately pre-dose inhaled study drug); post-dose at 5 minutes (min), 15 min, 30 min, and 1 hour (hr), 2 hr, 4 hr, 9 hr, 12 hr, 16 hr, 20 hr, and 24 hr post-dose on Day 42.	Day 42
Tmax and Tlast of FF at Day 42	tmax is defined as the time to reach the observed maximum concentration, and tlast is defined as the time of the last observed quantifiable concentration on Day 42.

Day 42
AUC(0-t) for VI on Day 42	Area under the concentration-time (AUC[0-t]) curve from time zero (pre-dose) to the last time of quantifiable VI concentration on Day 42 was measured. Samples were collected at the following times: 0 (immediately pre-dose inhaled study drug); post-dose at 5 minutes (min), 15 min, 30 min, and 1 hour (hr), 2 hr, 4 hr, 9 hr, 12 hr, 16 hr, 20 hr, and 24 hr post-dose on Day 42.	Day 42
Cmax for VI on Day 42	Cmax is defined as the maximum observed concentration on Day 42. Samples were collected at the following times: 0 (immediately pre-dose inhaled study drug); post-dose at 5 minutes (min), 15 min, 30 min, and 1 hour (hr), 2 hr, 4 hr, 9 hr, 12 hr, 16 hr, 20 hr, and 24 hr post-dose on Day 42.
