E.2.2

Secondary objectives of the trial

• To evaluate the efficacy of crinecerfont, compared with placebo, in reducing daily glucocorticoid dosage while maintaining adrenal androgen control.

- Have a medically confirmed diagnosis of classic CAH due to 21- hydroxylase deficiency.
- Be on a stable regimen of glucocorticoid treatment for CAH.
- Have elevated adrenal androgens.
- If treated with fludrocortisone, dose should be stable for at least 1 month prior to screening. Regardless of fludrocortisone treatment, upright plasma renin activity (PRA) (in the absence of medications that confound interpretation of PRA) during screening should be <3× ULN and >lower limit of normal on the subject's usual sodium intake (if PRA >2 × ULN and <3 × ULN, subject must have normal age-specific systolic blood pressure and heart rate and serum potassium <ULN.

E.4

Principal exclusion criteria

- Have a diagnosis of any of the other forms of classic CAH.
- Have a history of bilateral adrenalectomy, hypopituitarism, or other condition requiring chronic daily therapy with oral glucocorticoids.
- Have a clinically significant unstable medical condition or chronic disease other than CAH
- Have a history of malignancy, unless successfully treated with curative intent and considered to be cured.
- Have a known history of clinically significant arrhythmia or abnormalities on screening ECG.
- Have a known hypersensitivity or allergy to any corticotropin-releasing hormone receptor antagonist or any component of the study drug.
- Females who are pregnant or lactating.
