Detailed Description
The study will compare the efficacy, safety and tolerability of twice daily Chronocort with twice daily immediate release hydrocortisone replacement therapy (IRHC) (Cortef®) over a randomized treatment period of up to 28 weeks in participants aged 16 years and over with known classic Congenital Adrenal Hyperplasia (CAH) due to 21 hydroxylase deficiency.

The probability that a randomly chosen participant from the Chronocort arm shows more clinical benefit after 28 weeks of randomized treatment than a randomly chosen participant from the IRHC arm (the probability of net clinical benefit).
The comparison between participants will be based on the Multidimensional Assessment of Fatigue (MAF) score.
The MAF is a 16 item scale that measures fatigue according to four dimensions: degree and severity, distress that it causes, timing of fatigue, and its impact on various activities of daily living, with a range of score from 1 - 10 per item to give a Global Fatigue Score of up to 50 with a high score indicating a worse outcome.

|
To compare Chronocort to IRHC in terms of the impact on QoL using the remaining self-completed SF-36® sub domains (excluding vitality).
Time Frame: Baseline to 4, 10, 16 and weeks of randomized treatment
|
The change from baseline to 4, 10, 16 and 28 weeks of randomized treatment in QoL using the remaining self-completed SF 36® sub-domains (excluding vitality) will be summarized and compared between treatment arms.
The SF-36 measures eight scales: physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE), and mental health (MH).
All components contribute in different proportions to the overall measures.
Where the minimum score is 0 and maximum score is 100, a high score is a more favorable score.
