Study Endpoints
Primary Endpoints
Percent Change From Baseline to Day 14 in 17-hydroxyprogesterone (17-OHP) Morning Window Averages
Baseline and Day 14

Percent changes in 17-OHP were assessed through the collection of samples from 0600 hours to 1000 hours both prior to study drug administration (i.e., at baseline) and after 14 days of study drug dosing. The 3 samples collected during this morning window at each visit were averaged and used to determine the percent change from baseline.

Secondary Endpoints
Percent Change From Baseline to Day 14 in Androstenedione Morning Window Averages
Baseline and Day 14
Percent Change From Baseline to Day 14 in Adrenocorticotropic Hormone (ACTH) Morning Window Averages
