Study Summary

This trial is testing a new four-drug combination to see if it can normalize growth in children with congenital adrenal hyperplasia. The children will be followed until they reach their final adult height to see if the new combination is effective.

Who is the study for?
This trial is for children with Congenital Adrenal Hyperplasia who haven't started puberty or are suppressing it. Boys aged 2-13 and girls aged 2-11, based on bone age, can join. Kids needing steroids for other illnesses or those not stabilized on standard treatments cannot participate.Check my eligibility
What is being tested?
The study compares a new four-drug combo (flutamide, testolactone, reduced hydrocortisone dose, fludrocortisone) to the usual care in kids with Congenital Adrenal Hyperplasia. It aims to see if growth normalizes using these drugs until they reach adult height.See study design
What are the potential side effects?
Possible side effects include hormonal imbalances due to Fludrocortisone and Hydrocortisone; Letrozole may cause bone pain or hot flashes; Flutamide might lead to liver issues or gastrointestinal discomfort.

Could you please share what other research studies have used Flutamide?

"As of now, 245 clinical trials are underway to study flutamide. 74 of those studies are in Phase 3. Torrance, California is homebase for many of these investigations, however there are 17760 total locations running related research."

Answered by AI

For what sorts of treatments is Flutamide usually prescribed?

"Flutamide has been shown to be an effective medical intervention for patients struggling with ulcerative colitis, malignant neoplasms, and varicella-zoster virus acute retinal necrosis."

Answered by AI

How many research subjects are included in this investigation?

"This research project is no longer recruiting patients. The study was created on 6/8/1995 and last updated 11/1/2022. Currently, there are 245 clinical trials for Flutamide admitting patients and 145 trials for adrenal hyperplasia, congenital that are actively looking for participants."

Answered by AI

Are volunteers still being sought for this research project?

"This research project, as specified on clinicaltrials.gov, is not looking for participants at this time. The date the trial was originally posted was 6/8/1995 and the last update to the posting was on 11/1/2022. There are other 390 trials that are open for enrollment currently."
