Study Endpoints
Primary Endpoints
Percentage of Subjects (n/N) With Suppression of Clinical Sexual Characteristics According to Tanner Staging (Breast Development in Females)
Week 4, Week 48 (Year 1), yearly for 5 years (Week 240), and Final Visit

Suppression of clinical sexual characteristics was defined as regression (improvement) or no progression of breast development in females. Tanner staging is a scale of physical development that defines primary and secondary sex characteristics including size of breasts. The final visit occurred at a mean age +/- SD of 11.05 +/- 1.14 years (range, 6.96 to 12.95 years).

Percentage of Subjects (n/N) With Suppression of Clinical Sexual Characteristics According to Tanner Staging (Genital Development in Males)
Week 4, Week 48 (Year 1), yearly for 5 years (Week 240), and Final Visit

Suppression of clinical sexual characteristics was defined as regression (improvement) or no progression of genital development in males. Tanner staging is a scale of physical development that defines primary and secondary sex characteristics including size of genitals. The final visit occurred at a mean age +/- SD of 12.35 +/-1.35 years (range, 10.71 to 14.07 years).
