This pre-screening study is designed to determine potential eligibility of adults with classic CAH due to 21-hydroxylase deficiency (21-OHD) for participation in the CAH-301 \[NCT04783181\] gene therapy trial with BBP-631.
This study is designed to evaluate the safety, tolerability, and efficacy of AAV5 based BBP-631 in adult participants diagnosed with classic congenital adrenal hyperplasia.
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. ...
This study was developed to determine if a combination of four drugs (flutamide, testolactone, reduced hydrocortisone dose, and fludrocortisone) can normalize growth in children with congenital adrenal hyperplasia. The study will take 60 children, boys and girls and divide them into 2 groups based on the medications given. Group one will receive the new four- drug combination. Group two will receive the standard treatment for congenital adrenal hyperplasia (hydrocortisone and fludrocortisone). The boys in group one will take the medication until the age of 14 at which time they will stop taking the four drug combination and begin receiving the standard treatment for congenital adrenal hyperplasia. Girls in group one will take the four drug combination until the age of 13, at which time they will stop and begin receiving the standard treatment for congenital adrenal hyperplasia plus flutamide. Flutamide will be given to the girls until six months after their first menstrual period. All of the children will be followed until they reach their final adult height. The effectiveness of the treatment will be determined by measuring the patient's adult height, body mass index, and bone density. \<TAB\>...
Background: * Congenital adrenal hyperplasia (CAH) is a genetic disorder of the adrenal gland. The adrenal gland is located in the abdomen and produces small amounts of hormones such as cortisol, aldosterone, and androgen. These hormones help control blood pressure, protect the body, and maintain good health, especially during development. People with CAH do not make enough cortisol and aldosterone, and make too much androgen. This can lead to serious medical problems. The standard treatment is to take pills that mimic the effects of cortisol and aldosterone. However, treatment with pills can have long-term side effects because of the higher doses needed, and may not work well for some people. * A possible new treatment for CAH is to use a pump to deliver cortisol under the skin. Similar pumps are often used to give insulin to people with diabetes. Researchers think that a cortisol pump might be able to help the body use the cortisol more effectively than taking pills. They want to compare the results of a cortisol pump and standard pill treatments for CAH. Objectives: - To compare the effectiveness of a cortisol pump with standard cortisol pill therapy for CAH. Eligibility: - Men and women at least 18 years of age who have CAH (see more details in Eligibility section below). Design: * This study will involve four inpatient hospital stays at the National Institutes of Health in Bethesda, MD over 6 months (spaced 2 months apart). The first and last stays will last about 5 days. The second and third stays will last about 3 days. * Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. * At the first study visit, participants will provide regular blood and urine samples. They will also have imaging studies. These studies will look at the bones, fat, and muscles in the abdomen and pelvis. * Participants will receive a cortisol pump during the first visit. They will be shown how to use the pump. They will also learn what to do, if they need to take extra "stress dose" cortisol pills. * At the second and third visits, the cortisol dose given with the pump will be adjusted as needed. Blood and urine samples will also be collected. No imaging studies are scheduled for these visits. * The last study visit will have the same tests as the first visit. Participants will be offered the chance to continue with the pump treatment for 1 more year, or go back to their standard pill treatment.

This is a Phase 3 study to evaluate the efficacy, safety, and tolerability of crinecerfont versus placebo administered for 28 weeks in approximately 81 pediatric participants with classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. The study consists of a 28-week double blind, placebo-controlled period, followed by 24 weeks of open-label treatment with crinecerfont. Subsequently, participants may elect to participate in the open-label extension (OLE) period. The duration of participation in the study is approximately 14 months for the core study and will be a variable amount of time per participant for the OLE (estimated to be approximately 3 years).
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.
21-hydroxylase deficiency (21-OHD) is an inherited disorder that results from a mutation on the CYP21A2 gene. It affects the adrenal glands and is the most common cause of congenital adrenal hyperplasia (CAH). 21-OHD CAH causes the body to produce an insufficient amount of cortisol and an excess of androgen, the type of hormone that produces male characteristics. The primary treatment for 21-OHD CAH, glucocorticoid replacement therapy, has been shown to cause bone loss. However, the elevated hormone levels caused by 21-OHD CAH may increase production of the protein osteoprotegerin (OPG), which in turn may protect against bone loss. This study will compare bone density and OPG levels in women who have 21-OHD CAH and have undergone a lifetime of glucocorticoid replacement therapy to that in women who have neither of these criteria. In doing so, the study will aim to determine the relationship between OPG and bone loss.
Congenital adrenal hyperplasia (CAH) is a genetic disorder that affects the amount of steroids that the body forms. The most common form of CAH is 21-hydroxylase deficiency (21OHD), which leads to cortisol deficiency and causes the development of mature masculine characteristics in newborn, prepubescent, and grown females, and prepubescent males. Prenatal treatment with dexamethasone, a corticosteroid, has been shown to reduce the masculinization of genitalia. However, the long-term effects of dexamethasone on the children who received it as fetuses and on mothers who were exposed to it while they were pregnant have not been determined. This study will investigate potential long-term adverse side effects of prenatal dexamethasone treatment in children and young adults who received dexamethasone as fetuses and their mothers who were exposed to it during pregnancy.
An investigation of the safety and efficacy of tildacerfont in participants with CAH.
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.
An investigation of the ability of Tildacerfont to reduce supraphysiologic glucocorticoid dosing in classic CAH subjects up to 76 weeks of treatment. Optional open label extension up to 240 weeks.
An investigation of the efficacy and safety of up to 70 weeks of treatment with Tildacerfont in subjects with classic CAH who have elevated biomarkers at baseline on their current GC regimen. Optional open label treatment extension period up to 240 weeks with 200mg Tildacerfont QD.
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.
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.
This qualitative interview-based study will investigate the impact that living with congenital adrenal hyperplasia has for women in the following areas: health-related quality of life (HRQL), psychological health, and health-seeking behaviors.
This study will examine and compare the effects of intense exercise on the release of catecholamines in patients with congenital adrenal hyperplasia (CAH) and in healthy persons. Catecholamines are hormones (adrenaline and noradrenaline) that are produced by the adrenal glands and released into the blood stream during stress, such as trauma, illness, intense exercise, or low blood sugar. The study will also assess exercise tolerance in patients with CAH, compared with healthy persons. Patients with CAH between the ages of 10 and 40 years who are managing well on standard treatment (glucocorticoids, mineralocorticoids) may be eligible for this study. Healthy volunteers that match the enrolled patients in age, sex, race and body fat will be recruited as control subjects. All candidates will be screened with a medical history, physical examination and electrocardiogram (EKG). Body fat will be measured using an instrument called a Bod Pod. The body fat measurement has two parts: first, the subject sits quietly in a large egg-shaped capsule for about 2 to 3 minutes; then the subject breathes into a plastic tube for one minute, followed by three quick panting breaths. Women will have a urine pregnancy test; pregnant women cannot participate in the study. Participants will undergo three exercise sessions on separate consecutive mornings after fasting overnight. Before each test, patients (not healthy volunteers) will take either an additional morning dose of hydrocortisone or a placebo (a lookalike pill with no active ingredient). Before each test a thin catheter (plastic tube) will be placed into an arm vein through a needle. A numbing cream can be applied to make the needle stick hurt less. Blood will be drawn through this intravenous (IV) line before, during and after the exercise tests. The first test is a maximal exercise test to determine the individual's maximum exercise fitness capacity. The second two and third tests are a standardized exercise tests. Before the two standardized tests, patients (not healthy volunteers) will take either an additional morning dose of hydrocortisone or a placebo (a lookalike pill with no active ingredient). All tests are done on a stationary bicycle. Maximal Exercise Test - The subject pedals on a stationary bicycle for about 10 minutes. After a 3-minute warm-up, the workload is increased continuously until either the subject can no longer continue or the physician stops the test for medical reasons. During the exercise, heart rate and heart activity are monitored with an EKG, and the subject wears a nose clip and mouthpiece connected to a breathing tube to measure oxygen use. Blood is drawn before and during the test, totaling no more than 2 tablespoons. Standardized Exercise Test - The subject pedals on a stationary bicycle for 20 minutes, while wearing the nose clip and mouthpiece to measure oxygen use. For the first 5 minutes, the subject pedals at a speed that elicits 50 percent of maximal effort (determined by the maximal exercise test); the next 10 minutes are at 70 percent of maximal effort; and the last 5 minutes are at 90 percent. Blood samples drawn before, during (at 15 and 20 minutes) and after exercise (at 30, 40 and 60 minutes) total less than 1/2 cup. Heart rate and heart activity are monitored during the test with an EKG, and temperature is measured before and at the end of the test.
The purpose of this study is to evaluate the long-term safety, tolerability, and efficacy of atumelnant (CRN04894).
The goal of this study is to help investigators to understand more about the development of characteristics related to being male or female (what is called gender development). The investigators will study girls with congenital adrenal hyperplasia (CAH) aged 10 to 13 to learn more about the girls' interests and activities, thoughts and feeling about being female, and family relationships. This will help investigators to understand the ways in which gender development is shaped by hormones and family relationships.
