A Ph2b to Evaluate Tildacerfont in the Reduction of Glucocorticoid Steroid Doses in Adult CAH

This is a study that evaluated the ability of tildacerfont to reduce the glucocorticoid steroid dose used by adult subjects with CAH. The first 24-weeks were a double-blind, placebo controlled, comparison of tildacerfont vs placebo. The following 52-weeks allowed all subjects to move to open label tildacerfont to continue to reduce steroid dose where appropriate, and observe long term safety. Subjects were offered a long term open label extension up to 240 weeks.
