E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Participants with CAH who have successfully completed Chronocort study DIUR-006 (sites in France and US only) or study DIUR-014.
2. Participants who are capable of giving signed informed consent/assent as described in Appendix 1 which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol. |
|
E.4 | Principal exclusion criteria |
Medical Conditions
1. Participants with clinical or biochemical evidence of hepatic or renal disease e.g., creatinine >2 times the upper limit of normal (ULN) or elevated liver function tests (alanine aminotransferase [ALT] or aspartate aminotransferase [AST] >2 times the ULN).
2. Participants with a history of malignancy (other than basal cell carcinoma successfully treated >26 weeks prior to entry into the study).
3. Participants with a history of bilateral adrenalectomy.
4. Participants with any other significant medical or psychiatric conditions that in the opinion of the Investigator would preclude participation in the study.
Prior/Concomitant Therapy
5. Participants with a co-morbid condition requiring daily administration of a medication or consumption of any material that interferes with the metabolism of glucocorticoids (examples at http://medicine.iupui.edu/clinpharm/ddis/clinical-table/).
6. Participants on regular daily inhaled, topical, nasal, or oral steroids for any indication other than CAH.
7. Participants anticipating regular prophylactic use of additional steroids e.g., for strenuous exercise.
Prior/Concurrent Clinical Study Experience
8. Participation in another clinical study of an investigational or licensed drug or device within 3 months prior to inclusion in this study, except for another clinical study with the current formulation of Chronocort.
Other Exclusions
9. Females who are pregnant or lactating.
10. Participants, who in the opinion of the Investigator, will be unable to comply with the requirements of the protocol.
11. Participants who routinely work night shifts and so do not sleep during the usual night-time hours.
12. Participants with a body weight of 50 kg or less. (Note: this exclusion criterion is only applicable for French sites).

E.5 End points |
E.5.1 | Primary end point(s) |
The safety of Chronocort over time, assessed
using, but not limited to, the following outcome
variables:

• Use of IRHC from the emergency packs for stress dosing or use of any additional glucocorticoid treatment during the study.
• Occurrence of adrenal crises throughout the study.
• Occurrence of AEs throughout the study.
• Change from pre-Chronocort baseline in safety laboratory assessments at each visit throughout the study.
• Change from pre-Chronocort baseline in vital signs at each visit throughout the study. |
