Investigational Therapy
Children with congenital adrenal hyperplasia (CAH) and bone ages of 2-13 years in boys and 2-11 years in girls were randomized to receive antiandrogen (flutamide 10mg/kg/day orally), aromatase inhibitor (testolactone - 20mg/ kg/day orally OR letrozole - 1.5mg/m\^2 body surface area orally), low-dose hydrocortisone (6-8 mg/m\^2/day orally), and fludrocortisone (100-200 mcg/day, depending on lab evaluation, orally). Participants received the four-drug regimen until the age of 13 in the girls and 14 in the boys and then were switched to standard therapy. Female participants on investigational drugs were continued on flutamide until attainment of final adult height or two years post menarche. Participants who experienced early puberty received GnRH agonist therapy: depot leuprolide 7.5-15 mg/kg monthly intramuscularly or deslorelin 4 mcg/kg/day (adjusted based on weight and response) subcutaneously.
Standard Therapy
Children with congenital adrenal hyperplasia (CAH) and bone ages of 2-13 years in boys and 2-11 years in girls received standard therapy/conventional treatment (with hydrocortisone and fludrocortisone). Participants received hydrocortisone approximately 10-15 mg/m\^2/day orally, not exceeding 25mg/m\^2/day, and fludrocortisone 100-200 mcg/day orally depending on lab evaluation. Participants who experienced early puberty received GnRH agonist therapy: depot leuprolide 7.5-15 mg/kg monthly intramuscularly or deslorelin 4 mcg/kg/day (adjusted based on weight and response) subcutaneously.

SECONDARY outcome

Timeframe: Followed to attainment of adult height, average of 11 years from date of randomization

Population: Modified intention-to-treat population, includes patients who were reassigned from investigational to standard therapy due to drug intolerance.

Adult height expressed in standard deviation score (SDS) units relative to the mid-parental height for the general population. Adult height is defined as incremental growth \< 1.5 cm over 12 months. Adult height SDS was based on National Health and Nutrition Examination Survey (Centers for Disease Control and Prevention, National Center for Health Statistics) data at 20 years old. Mid-parental height was calculated based on reported parental heights calculated as (father's height (cm) + mother's height (cm))/ 2 ± 6.5 (cm).

SECONDARY outcome

Timeframe: At date of randomization and at pubertal onset (average of seven years from date of randomization)

Population: Modified intention-to-treat population, includes patients who were reassigned from investigational to standard therapy due to drug intolerance.

Predicted adult height was calculated using the bone age at the baseline visit or the first available bone age, using the Bayley-Pinneau method. Predicted adult height was calculated as the standard deviation score (SDS) units relative to the general population based on the National Health and Nutrition Examination Survey data (Centers for Disease Control and Prevention (CDC), National Center for Health Statistics) at 20 years old. Baseline was defined as time of randomization. Pubertal onset was defined as when patients entered puberty (Tanner 2 breast in females, testicle size ≥ 4 mL in males) or completed therapy with either aromatase inhibitor and/or GnRHa (age 13 years in girls and 14 years in boys).

Measured during the study period from baseline visit to pubertal onset visit (visits occurring approximately every 6 months) and from pubertal onset to adult height. Baseline was defined as date of randomization. Pubertal onset was defined as when patients entered puberty (Tanner 2 breast in females, testicle size ≥ 4 mL in males) or completed therapy with either aromatase inhibitor and/or GnRHa (age 13 years in girls and 14 years in boys). Final visit was defined as attainment of adult height with incremental growth \< 1.5 cm over 12 months.

n=21 Participants
Children with congenital adrenal hyperplasia (CAH) and bone ages of 2-13 years in boys and 2-11 years in girls were randomized to receive antiandrogen (flutamide 10mg/kg/day orally), aromatase inhibitor (testolactone - 20mg/ kg/day orally OR letrozole - 1.5mg/m\^2 body surface area orally), low-dose hydrocortisone (6-8 mg/m\^2/day orally), and fludrocortisone (100-200 mcg/day, depending on lab evaluation, orally). Participants received the four-drug regimen until the age of 13 in the girls and 14 in the boys and then were switched to standard therapy. Female participants on investigational drugs were continued on flutamide until attainment of final adult height or two years post menarche. Participants who experienced early puberty received GnRH agonist therapy: depot leuprolide 7.5-15 mg/kg monthly intramuscularly or deslorelin 4 mcg/kg/day (adjusted based on weight and response) subcutaneously.

n=12 Participants
Children with congenital adrenal hyperplasia (CAH) and bone ages of 2-13 years in boys and 2-11 years in girls were randomized to receive antiandrogen (flutamide 10mg/kg/day orally), aromatase inhibitor (testolactone - 20mg/ kg/day orally OR letrozole - 1.5mg/m\^2 body surface area orally), low-dose hydrocortisone (6-8 mg/m\^2/day orally), and fludrocortisone (100-200 mcg/day, depending on lab evaluation, orally). Participants received the four-drug regimen until the age of 13 in the girls and 14 in the boys and then were switched to standard therapy. Female participants on investigational drugs were continued on flutamide until attainment of final adult height or two years post menarche. Participants who experienced early puberty received GnRH agonist therapy: depot leuprolide 7.5-15 mg/kg monthly intramuscularly or deslorelin 4 mcg/kg/day (adjusted based on weight and response) subcutaneously.
Standard Therapy
n=20 Participants
Children with congenital adrenal hyperplasia (CAH) and bone ages of 2-13 years in boys and 2-11 years in girls received standard therapy/conventional treatment (with hydrocortisone and fludrocortisone). Participants received hydrocortisone approximately 10-15 mg/m\^2/day orally, not exceeding 25mg/m\^2/day, and fludrocortisone 100-200 mcg/day orally depending on lab evaluation. Participants who experienced early puberty received GnRH agonist therapy: depot leuprolide 7.5-15 mg/kg monthly intramuscularly or deslorelin 4 mcg/kg/day (adjusted based on weight and response) subcutaneously.

SECONDARY outcome

Timeframe: Final visit, average of 11 years from date of randomization

Population: Modified intention-to-treat population, includes patients who were reassigned from investigational to standard therapy due to drug intolerance.

Anterior posterior spine bone mineral density (BMD) measured by dual-energy x-ray absorptiometry (DEXA) scan at final visit. The instrument specific comparisons (in standard deviations) were made to the average peak bone mass of a normal population, i.e. to the average bone mass of persons of the same age and sex as the patient. Final visit is defined as attainment of adult height with incremental growth \< 1.5 cm over 12 months.
