Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of NBI-74788 in Pediatric Subjects...

CAH - Congenital Adrenal Hyperplasia

This is a Phase 2, open-label, multiple-dose, dose-escalation study to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of NBI-74788 in approximately 12 pediatric female and male subjects (14 to 17 years of age) with a documented medical diagnosis of classic 21-hydroxylase deficiency congenital adrenal hyperplasia (CAH).

Comparison of Two Forms of Hydrocortisone in Patients With Congenital Adrenal Hyperplasia

Congenital Adrenal Hyperplasia21-Hydroxylase Deficiency1 more

This study will test a new, extended release form of hydrocortisone called Chronocort in patients with congenital adrenal hyperplasia (CAH). People with CAH do not make enough of the adrenal hormones cortisol and aldosterone, and their adrenal glands make too much of the sex hormone androgen. Medicines called glucocorticoids (hydrocortisone, dexamethasone and prednisone) are currently used to treat CAH, but finding the best dose of these drugs that effectively lowers androgens without causing undesirable side effects, such as weight gain and slow growth rate in children, is often difficult to achieve. Adolescents and adults with CAH due to 21-hydroxylase deficiency may be eligible for this study. Children 16 years of age and older are eligible with confirmation by bone age that they are no longer growing. Participants undergo the following tests and procedures during two inpatient visits one month apart at the NIH Clinical Center: Medical history and physical examination. Medications: Following 7 days of Cortef (standard drug treatment for CAH), patients begin taking Chronocort on day 3 of hospitalization and continue the tablets once a day for 1 month. Blood tests: A catheter (plastic tube) is inserted in a vein and left in place for frequent blood draws in order to avoid repeated needlesticks. Blood is drawn for chemistries, blood count, pregnancy test in women, and for serial tests (up to 26 samples in a 24-hour period) to measure hormone levels. 24-hour urine test. Height and weight measurements. Between the two hospitalizations, patients are contacted by NIH weekly to check for possible side effects from Chronocort. Two weeks after the first visit, patients also will have blood drawn by their regular doctor or a local clinic. A few days before the second hospitalization, patients undergo a 20-minute telephone questionnaire about energy level and well being. About 30 days after discharge from the second hospitalization, patients are followed up with a telephone call to see how they are doing.

Comparison of Chronocort® With Standard Glucocorticoid Therapy in Patients With Congenital Adrenal...

Congenital Adrenal Hyperplasia

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.

Glucocorticoid Receptor Blockade With Mifepristone in Patients With Mild Adrenal Hypercortisolism...

Mild Hypercortisolism

The purpose of this study is to determine whether mifepristone is an effective treatment for hyperglycemia due to mild hypercortisolism. To test the hypothesis that GR blockade with mifepristone will decrease the severity of metabolic syndrome features as measured by waist circumference, lipid profile, body mass index, blood pressure and insulin resistance, measured by HOMA-IR score. To test the hypothesis that GR blockade with mifepristone will improve QoL, depression and anxiety scores, measured by validated assessments, in patients with mild hypercortisolism.

Pilot Study to Characterize and Examine the Pharmacokinetics and Efficacy of Chronocort® in Adults...

Endocrine DiseaseAdrenal Insufficiency1 more

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.

Dexamethasone Treatment of Congenital Adrenal Hyperplasia

Adrenal HyperplasiaCongenital

The purpose of this study is to determine if dexamethasone given at night is a more effective treatment for congenital adrenal hyperplasia in young children than standard three times per day hydrocortisone. Our hypothesis is that nocturnal dexamethasone will lead to more efficient suppression of the hypothalamic-pituitary-adrenal axis. We performed a cross-over trial comparing hormonal control during two 24-hour hospitalizations, one on hydrocortisone and one on nocturnal dexamethasone.

CAH - Congenital Adrenal Hyperplasia

This is a Phase 2, open-label, multiple-dose, dose-escalation study to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of NBI-74788 in up to 30 adult female and male subjects (18 to 50 years of age) with a documented medical diagnosis of classic 21-hydroxylase deficiency congenital adrenal hyperplasia (CAH). The study will include a sequential-cohort design with four NBI-74788 dosing regimens, with each regimen administered for 14 days.

A Study of ATR-101 for the Treatment of Congenital Adrenal Hyperplasia

Congenital Adrenal Hyperplasia

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.
