Brief Summary:
An investigation of the efficacy and safety of up to 70 weeks of treatment with Tildacerfont in subjects with classic CAH who have elevated biomarkers at baseline on their current GC regimen. Optional open label treatment extension period up to 240 weeks with 200mg tildacerfont QD.

Condition or disease Intervention/treatment Phase
Congenital Adrenal Hyperplasia Drug: Tildacerfont/Placebo Phase 2

Detailed Description:
This is a study that will test the efficacy and safety of Tildacerfont. The first 12-weeks will be a double-blind, placebo controlled, dose ranging study. The following 58-weeks will assess the long term safety of Tildacerfont. Optional open label treatment extension period up to 240 weeks with 200mg tildacerfont QD.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

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 supraphsiologic 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

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
