Three Drug Combination Therapy Versus Conventional Treatment of Children With Congenital Adrenal Hyperplasia
United States66 participantsStarted 1995-06-08
Plain-language summary
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 two years after their first menstrual period or until adult height.
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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
* INCLUSION CRITERIA:
Subjects will be boys with bone ages 2 to 13 years and girls with bone ages 2 to 11 years with CAH due to classic 21-hydroxylase deficiency.
Subjects must either not yet have undergone pubertal activation of the hypothalamic-pituitary-gonadal axis, or, if pubertal activation has occurred, must be receiving a GnRH agonist to suppress secondary central precocious puberty.
Children with a bone age of 1 to 2 years may enroll in the protocol for optimization of conventional therapy, but will not be randomized to a study arm until the bone age reaches 2.
EXCLUSION CRITERIA:
Children who have concurrent illnesses requiring glucocorticoid treatment (such as severe asthma), or requiring drugs that markedly alter hydrocortisone metabolism (such as anticonvulsants), and children who cannot be brought into reasonable control with conventional treatment (an unusual occurrence).
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
