Active clinical trials for "Adrenogenital Syndrome"

The purpose of this study is to determine the minimum dose of abiraterone acetate needed to decrease serum androstenedione to age-appropriate levels in premenopausal women on steroid replacement for classic 21-hydroxylase deficiency.

This is an open-label, non-randomized crossover design feasibility trial comparing oral hydrocortisone treatment with interval bolus delivery (pulsatile) of subcutaneous hydrocortisone via infusion pump in children with congenital adrenal hyperplasia. Eight children, ages 4-18 yrs, will have 24-hr pharmacokinetic and pharmacodynamic profiles of cortisol, 17-hydroxyprogesterone and androstenedione concentrations while on oral hydrocortisone therapy (admission 1), during an initial trial of the subcutaneous hydrocortisone pump (admission 2), and after 6 weeks of subcutaneous hydrocortisone pump treatment (admission 3). An integrated pharmacokinetic and pharmacodynamic model will be used to determine cortisol, 17-hydroxyprogesterone and androstenedione parameters to compare the duration of time subjects have these concentrations outside acceptable ranges.

This study was a single-center randomized controlled trial which lasted 14 days and consisted of two stages (run-in period (stage I) and intervention period (stage II) each contain 7 days without potassium supplement. If participants meet the enrollment criteria at the end of stage I, they were assigned to the low sodium group (50mmol/d) or normal sodium group (100mmol/d), and then continued to finish stage II. The primary outcome was the change in serum potassium after exposure to normal sodium / low sodium diet and the secondary outcome was the assessment of BP change following a normal sodium / low sodium diet. Patients were given nifedipine controlled-release tablets 30 mg/d to lower blood pressure and were not provided any potassium supplements during the two stages. If the subject has an increase in BP (>180/110 mmHg), the dose of nifedipine controlled-release tablets will be increased to 60 mg/d. Patients will be withdrawn from the study if they cannot tolerate the diet or their serum potassium were below 2.8 mmol/L.

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).

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 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.

This study is an open-label, randomised, titration-blinded, parallel arm, multicenter study to compare twice daily Chronocort® with standard care in participants with Congenital Adrenal Hyperplasia (CAH). This study will be conducted in the USA.

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.

Primary aldosteronism (PA) is a common cause of secondary hypertension, which is characterized by excessive aldosterone production by the adrenal gland. Excessive aldosterone can significantly increase the risk of cardiovascular disease and stroke. Patients with aldosterone-producing adenoma (APA) or unilateral hyperplasia (UAH) can be cured by unilateral adrenalectomy. The adrenal cortex is the outer part of the adrenal gland and is subdivided into three layers- the zona glomerulosa, the zona fasciculata, and the zona reticularis. And the outermost layer is the zona glomerulosa, and it's full of cells that make the hormone aldosterone. Although it has been investigated that the main cause of APA or UAH is the mutations of different calcium ion channels, including KCNJ5, CACNA1D, CLCN2 et al, it is still unknown whether there are any other changes of other proteins in different layers. Therefore, the investigators designed the study to characterize the proteomics profiles of adrenal adenoma/hyperplasia leading to primary aldosterone and identify biomarkers for early identification of PA by using spatial proteomics. The samples from adrenal adenoma or hyperplasia will be collected and analyzed by spatial proteomics in Hangzhou Jingjie Biotechnology Co., Ltd. The differentially expressed proteins in different layers will be screened out between APA and UAH, APA and its adjacent normal tissues, and UAH and its adjacent normal tissues, respectively. And KEGG analysis will be conducted to determine enriched pathway in these differentially expressed protein, respectively.

The conventional glucocorticoid replacement therapy in congenital adrenal hyperplasia (CAH) renders the cortisol levels unphysiological, which may cause symptoms and long-term complications. Glucocorticoid replacement is technically feasible by continuous subcutaneous hydrocortisone infusion (CSHI), and can mimic the normal diurnal cortisol rhythm. This method was recently applied to treat a patient through a critical phase of puberty. This is a clinical trial aiming to evaluate CSHI treatment in patients with CAH. The main objective is to determine the effects of CSHI on metabolic parameters (androstenedione and 17-hydroxyprogesterone profiles, and testosterone,adrenocorticotropic hormone(ACTH), cortisol, and bone markers), and to determine the required glucocorticoid doses. Secondary objectives are to determine effects on clinical status, body weight, blood pressure and other metabolic parameters, as well as on subjective health status (AddiQoL, SF36).
