Filter by:Subjects completing study DIUR-005 and those who have already completed study DIUR-003 will be offered the opportunity either to continue Chronocort® therapy or to switch from their current glucocorticoid therapy to Chronocort® in this open-label study.
This was an open label, randomised, single dose study, comprising Part A (undertaken in two separate three-period crossover cohorts denoted as A1 and A2) and Part B (undertaken in one four-period crossover cohort), to evaluate the PK of Chronocort® in healthy male volunteers. The washout interval in both Part A and Part B was 1-week in between each treatment period.
This was an open label, randomized, single dose, three period crossover pharmacokinetic study of Chronocort® in 30 healthy male volunteers. The study was conducted in smaller sub groups (Group 1, n=18 and Group 2, n=12).
The study will investigate 27 hour profiles of hormones in the subcutaneous tissue of healthy subjects and patients with Addison's, Congenital Adrenal Hyperplasia, Growth Hormone Deficiency, acromegaly, Cushings and Primary Hyperaldosteronism during conventional diagnostic and therapeutic follow-up. The 27 hour monitoring by ULTRADIAN takes into account the rhythm of hormones throughout the day. It is hoped that this information may in the future improve and simplify diagnostic procedures. Follow-up of patients in endocrinology still remains difficult including clinical signs of over and under-treatment, questionnaires of quality of life and blood testing necessitating often retesting. Simplification of the diagnostic procedure by obtaining detailed knowledge about the rhythm of hormones may contribute to the improvement and individualization of treatment and may decrease morbidity and mortality of endocrine patients.
This is a Phase 2 multicenter, single-blind, multiple dose study to evaluate the safety and efficacy of orally administered ATR-101 in subjects with classic congenital adrenal hyperplasia (CAH). Treatment duration will range from a minimum of approximately 2 months to 6 months per subject. A subject may receive a minimum of one dose level or up to a maximum of 5 dose levels, in sequentially increasing dose strengths. Each dose level will last 28 days.
The classic form of 21-hydroxylase deficiency (prevalence 1/15,000) is the most common cause of congenital adrenal hyperplasia (CAH). This autosomic recessive disease is responsible for virilization of the external genitalia in girls through androgen hypersecretion during fetal life. Since 1984, the Lyon Pediatric Endocrinology group has proposed prenatal dexamethasone (DEX) for all fetuses at risk of CAH With the aim of preventing fetal androgen hypersecretion in affected girls and avoiding poor long-term results from reconstructive surgery. Prenatal DEX was used in Europe and the USA but its use was recently suspended: in 2007, a Swedish study conducted on 26 children treated with DEX in utero for a short period of time reported cognitive impairments. These data were not confirmed by an American study on the short-term DEX use, which showed potential cognitive impairments in CAH children exposed to DEX for long periods of time. These confusing and controversial results have caused the scientific community to question its position and have resulted in the suspension of the use of prenatal DEX with drastic consequences for CAH girls (virilization; genital surgery etc.). In this context, an evaluation of neuropsychological development under in utero DEX is essential to validate its indication for use during the prenatal period. This study will evaluate outcomes using prospective cognitive and emotional assessments. It will first focus on the unaffected children previously treated in utero in order to assess the adverse effects of the drug. The study will then assess the children with CAH for whom DEX could have beneficial effects.
This study is a parallel arm, randomised, open-label study, including dose titration and admissions for four overnight stays for 24-hour endocrine profiles. It will compare the efficacy, safety and tolerability of Chronocort® with standard glucocorticoid replacement therapy in the treatment of congenital adrenal hyperplasia (CAH) over a treatment period of 6 months. Dose titration decisions in both treatment groups will be made by a central independent physician, blinded to the treatment arm, using information generated from the 24-hour endocrine profiles. Each treatment arm will be subject to the same titration rules throughout the study, ensuring that opportunities for optimisation and control of androgens are the same in both groups.
Children with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency tend to have elevated circulating levels of androgens, which can accelerate skeletal maturation and adversely impact adult height. Additionally, these children require supraphysiologic doses of hydrocortisone to suppress secretion of adrenal androgen precursors, and this treatment can retard linear growth. This study seeks to use oral abiraterone acetate (Zytiga)as an adjunct to approved CAH therapy (oral hydrocortisone and fludrocortisone) for pre-pubescent children with classic 21-hydroxylase deficiency in order to reduce daily requirement of hydrocortisone. In this Phase 1 study, the investigators will determine the minimum effective dose of abiraterone acetate that normalizes androstenedione levels during the 7-day Treatment Period.
Congenital adrenal hyperplasia (CAH) results from a deficiency of a key enzyme in the biosynthesis of cortisol, mainly 21-hydroxylase, resulting in its classic form a neonatal salt loss syndrome and / or a virilization syndrome in girls. The treatment of the disorder in adulthood involves administering steroidal compounds with the aim to substitute the gluco- and mineralocorticoid deficit on the one hand, and effectively curb the adrenal hyperplasia and adrenal androgen pathway in girls . The terms of glucocorticoid treatment are not clearly codified and are based on several steroidal compounds and various protocols. The advantages in terms of adrenal suppression and disadvantages - including bone and metabolic - different treatments have not been clearly established in the literature. The main objective of this study is to compare among adults with HCS in its classical form the impact on hormonal parameters adrenal suppression glucocorticoid of 3 types of treatment administered to equivalent dose and according to the usual procedures. The secondary objective is to compare in the same patients the impact of different drugs and treatments on several metabolic bone parameters. The study will include 40 adult patients bearing a HCS in its classical form and will include 3 treatment sequences of eight weeks each, during which they will be administered sequentially in random order at random and according to the known equivalences hydrocortisone, prednisone (CORTANCYL) and dexamethasone (DECTANCYL). Randomization will be stratified based on previous DMARDs in the investigation that may be different for different patients, knowing that France hydrocortisone and dexamethasone are used mainly for the treatment of congenital adrenal hyperplasia. The judging criteria will be: i) the criteria of adrenal hormone suppression: plasma levels of testosterone, androstenedione, 17 OHP, ACTH and diurnal variations of the 17 OH progesterone salivary ii) the criteria of the metabolic impact of glucocorticoids: plasma glucose levels , blood lipids, and insulin sensitivity index HOMA-R calculated from glucose and insulin, iii) the criteria of bone impact of glucocorticoids: plasma for CTX bone resorption and bone alkaline phosphatase P1NP for bone formation iv) the living quality criteria evaluated by the PGWB Questionnaire (Psychological General Well-Being). The duration of the study period will be 24 months.
This is a Phase 1, multicenter, open-label, single-dose study to evaluate the safety and tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of NBI-77860 in subjects with congenital adrenal hyperplasia (CAH). The study will be conducted in approximately 15 adolescent females (12-18 years of age) with a documented medical diagnosis of classic 21-hydroxylase deficiency CAH. The study will include three independent dose cohorts of NBI-77860 (approximately 5 subjects per dose cohort). Ascending doses will be evaluated as part of a sequential-cohort design.
