Healthy volunteers: no

Brief summary:
The purpose of this study is to gather safety and effectiveness information about a new formulation of Hydrocortisone (Chronocort®) used to treat patients with a disease called congenital adrenal hyperplasia (CAH). Hydrocortisone is the man-made version of the hormone cortisol, which is released in the body following a regular daily pattern. The objective of the study is to measure the levels of hydrocortisone that are absorbed into the bloodstream once Chronocort® is taken and what affects it has on other hormones in the body. Since Chronocort® is anticipated to mimic the same release pattern of cortisol in the body, it is hoped that patients with CAH will be treated more effectively to manage their disease.

Detailed description:
This study is a Phase 2 pilot study to characterize and examine the pharmacokinetics and efficacy profile of Chronocort® in adults with congenital adrenal hyperplasia (CAH). It is designed as a two-part, single cohort, open label, multiple dose Phase 2 pilot study to: (Part A) characterize and examine the pharmacokinetics (PK) and disease bio-marker behavior following short-term dosing with Chronocort®; and to (Part B) examine the disease control after six months dose titration with Chronocort® in adults with CAH.

Arms:
arm 1: Chronocort Modified Release Capsules, 5mg, 10mg and 20mg Dosing frequency twice-daily (mane and nocte) Dose setting by titration to achieve optimal biochemical and therapeutic response

Interventions: intervention 1: Hydrocortisone Modified Release Capsules
Intervention descriptions: intervention 1: Patients with congenital adrenal hyperplasia standardised on conventional therapy is enrolled onto the study and treatment is switched to Chronocort, initially for pharmacokinetic assessment followed by longer-term biochemical and efficacy assessment
