Eligibility
Key inclusion criteria
* Male and female subjects over 18 years old, inclusive
* Has a known childhood diagnosis of classic CAH due to 21-hydroxylase deficiency based on genetic mutation in CYP21A2 and/or documented elevated 17-OHP and currently treated with HC, HC acetate, prednisone, prednisolone, methylprednisolone (or a combination of the aforementioned GCs)
* Has been on a stable supraphysiologic dose of GC replacement =15 mg/day and =60 mg/day in HC equivalents
* For subjects with the salt-wasting form of CAH, subject has been on a stable dose of mineralocorticoid replacement for =1 month before screening
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Has a known or suspected diagnosis of any other known form of classic CAH (not due to 21 hydroxylase deficiency)
* Has a history that includes bilateral adrenalectomy or hypopituitarism
* Has a history of allergy or hypersensitivity to Tildacerfont, any of its excipients, or any other CRF1 receptor antagonist
* Current treatment with dexamethasone as GC therapy for CAH. Prior treatment with dexamethasone is allowed as long as the transition to an alternative GC regimen (eg, HC, prednisone, or prednisolone) has resulted in a stable dose of GC replacement for =1 month before screening.
* Shows clinical signs or symptoms of adrenal insufficiency
