5 Clinical Trials for Congenital Adrenal Hyperplasia
The purpose of this Phase 2, open-label, sequential dose cohort study is to evaluate the safety, efficacy, and pharmacokinetics (PK) of CRN04894 in participants with classic congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency.
Background: Children with congenital adrenal hyperplasia (CAH) can survive well into adulthood with proper treatment. But the change from pediatric to adult care can be challenging. Many people with CAH need extra support as they learn to take control of their own health care needs. Researchers have studied how people respond to different types of patient education. Now researchers want to find out if virtual education, via computer, is a good way to teach people how to manage CAH as they become adults. Objective: To test a virtual method of delivering patient education to adolescents and young adults with CAH. Eligibility: Adolescents and young adults aged 16 to 22 years who have CAH. They must already be enrolled in Natural History Study Protocol 06-CH-0011. Design: Participants may take part in the study remotely; they may also come to the clinic. They will have 3 visits in 1 year. Participants will complete questionnaires. Topics will include what they know about CAH; whether they remember to take their medications on their own; and whether they schedule their own appointments. They will be asked about their quality of life. They will be asked about their physical and emotional health. All participants will be taught how to care for themselves. The participants will be divided into 2 groups. Some will watch an 11-minute video on CAH that focuses on their goals as they become adults. The others will receive standard education. After 6 months, participants will receive CAH education again. After 12 months, participants will repeat the questionnaires from their first visit.
The purpose of this study is to evaluate the long-term safety, tolerability, and efficacy of atumelnant (CRN04894).
This study will evaluate and gather information in patients with genetic causes of too much androgen (male-like hormone) in order to better understand the effects of too much androgen and describe problems associated with it. Too much androgen in childhood, if untreated, results in rapid growth and early puberty with early cessation of growth and short stature in adulthood. Too much androgen in adulthood may result in infertility, and women may have excess facial hair, acne and a more male-like appearance. Excess androgen may also affect mood and behavior and possibly the secretion of other hormones, such as insulin. Two genetic diseases that result in early childhood androgen excess are congenital adrenal hyperplasia (CAH) and familial male-limited precocious puberty (FMPP). Patients with known or suspected CAH due to 21-hydroxylase deficiency, 11- hydroxylase deficiency, or 3-beta-hydroxysteroid dehydrogenase deficiency and males with known or suspected FMPP may be eligible for this study. Patients with both classic and non-classic CAH are eligible, and patients with androgen excess of unknown cause may be eligible. Participants undergo the following procedures: * Medical history and physical examination. * Fasting blood tests for analysis of hormones, blood chemistries including blood sugar and cardiovascular risk factors such as lipids. * Oral glucose tolerance test for patients with elevated insulin levels. For this test, a catheter (plastic tube) is placed in a vein in the patient's arm. The patient drinks a sugar-containing fluid and blood samples are collected through the catheter at intervals starting with drinking the solution, and then 30, 60 and 120 minutes after drinking the solution. * 24-hour urine collection to measure hormone levels in the urine. * DNA testing for patients with 21-hydroxylase deficiency to help identify the type of genetic mutation responsible for the disease. * X-ray of the left hand to measure bone age in growing children. The x-ray is used to determine how far into puberty the child is and how much growth potential is left in the bones. * A pelvic ultrasound in females and testicular ultrasound in males to evaluate the size and development of the gonads (ovaries in females and testes in males). * Cognitive and psychological tests, including an IQ test and evaluation of memory, achievement and behavior. * Other tests and evaluations based on medical need. The schedule for these procedures varies. In a part of the study involving only patients with CAH, growing children are evaluated twice (once in childhood and once after reaching adult height), and adults are evaluated once. In another part of the study involving patients with CAH and FMPP, growing children are seen twice a year, and adults and children who have reached adult height may be seen annually. Additional visits may be scheduled if medically indicated. In this part of the study, females are asked to keep a record of their periods after their first menstrual cycle. ...
The purpose of this study is to find out whether the study drug, metyrapone, is safe and effective in treating participants with Mild Autonomous Cortisol Secretion (MACS).
