Acerca de la investigación

The purpose of this study is to evaluate the efficacy, safety, PK, and PD of atumelnant in adults with classic CAH due to 21-OHD.

Leer la descripción completa

This is a Phase 3, global, multicenter, randomized, double-blind, placebo-controlled study in adult participants (male or female age ≥18 to \<75 years) with classic CAH due to 21-OHD who have been on a stable regimen of GCs for at least 2 months to evaluate efficacy, safety, PK, and PD of atumelnant administered once per day. Following a 3- to 6-week Screening Period, eligible participants will enter the Treatment Period where they will be randomly assigned in a 2:1 ratio to receive either atumelnant 80 mg once daily (with an option for dose escalation to 120 mg once daily at Week 20) or placebo.

A total of approximately 150 participants may be enrolled in the study.

3. Have classic CAH due to 21-OHD confirmed by the Investigator.
4. Participants with Visit 2 levels of morning serum A4 as follows:

* A4 \>ULN and treated with \<11 mg/m2/day (physiologic) GC doses
* OR normal A4 (\>0.5xULN to ≤1xULN) and treated with ≥14 mg/m2/day GC doses
* OR A4 \>ULN and treated with ≥11 mg/m2/day GC doses.
5. On a stable (defined as no dose change of \>5 mg/day hydrocortisone equivalent within 2 months prior to Screening) regimen of GC replacement (e.g., hydrocortisone, prednisolone, prednisone, methylprednisolone, meprednisone, dexamethasone, cortisone acetate) at the time of informed consent.
6. If treated with mineralocorticoids (fludrocortisone), the dose should be stable for at least 1 month prior to Screening without orthostatic hypotension, and with serum sodium and potassium in the normal range.
7. If on estrogen therapy (any route), the dose must be stable for at least 3 months prior to Screening.

Exclusion Criteria:

1. Diagnosis of any form of CAH other than classic 21-OHD.
2. History of bilateral adrenalectomy, hypopituitarism, or other condition requiring chronic GC therapy.
3. Clinically significant medical condition or abnormal laboratory tests, as judged by the Investigator, other than CAH.
4. Concomitant mental condition rendering him/her unable to understand the nature, scope, and possible consequences of the study, and/or evidence of poor compliance with medical instructions.
