Three Drug Combination Therapy Versus Conventional Treatment of Children With Congenital Adrenal Hyperplasia

• Status: Active, not recruiting
• Trial end date: 2022-12-31
• Target enrollment: 0
• Participant gender: All

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 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.... Phase: Phase 2Accepts Healthy Volunteers? No

Criteria

• INCLUSION CRITERIA:

Subjects will be boys with bone ages 2 to 13 years and girls with bone ages 2 to 11 years with classic 21-hydroxylase.

Subjects must either not yet have undergone pubertal activation of the hypothalamic-pituitary-gonadal axis, or, if pubertal activation has occurred, must be receiving an LHRH 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).
