Inclusion Criteria: - Clinical diagnosis of isosexual central precocious puberty with onset of Tanner scores of Stage II for breast or pubic hair earlier than age 8.0 years in girls or Stage II for pubic hair or genitalia earlier than 9.0 years in boys. - Confirmation of diagnosis by a pubertal response to a gonadotropin-releasing hormone (GnRH) stimulation test (LH > 10 U/L at baseline). - Chronological age less than 9.0 years in girls or less than 10.0 years in boys at time of first dosing. - Bone age advanced at least 1 year beyond the chronological age at entry into the study. - The condition may be idiopathic or secondary to another lesion. If secondary, therapy of the primary condition will have been undertaken and stabilized. - No evidence of abnormal pituitary, adrenal, thyroid and gonadal function except for premature secretion of gonadotropins. Exclusion Criteria: - Irradiation to the central nervous system. - Prior therapy with medroxyprogesterone acetate and/or with any GnRH analog (including prior treatment with daily subcutaneous and depot formulations of leuprolide acetate). |

Primary | Percentage of Subjects (n/N) With Suppression of Clinical Sexual Characteristics According to Tanner Staging (Breast Development in Females) | 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). | Week 4, Week 48 (Year 1), yearly for 5 years (Week 240), and Final Visit | No |
Primary | Percentage of Subjects (n/N) With Suppression of Clinical Sexual Characteristics According to Tanner Staging (Genital Development in Males) | 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). | Week 4, Week 48 (Year 1), yearly for 5 years (Week 240), and Final Visit | No |
Secondary | Mean Peak Stimulated Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH) Concentrations | Mean peak stimulated visit LH and FSH concentrations were assessed according to the DELFIA (registered trademark) assay. The final visit for measurement of both hormone concentrations occurred at a mean age +/- SD of 11.13 +/- 1.23 (range, 6.73 to 14.07) years. | Baseline, Weeks 4, 12, 24, 48 (Year 1), yearly for 5 years (Week 240), and Final Visit | No |
Secondary | Mean Stimulated Estradiol Concentrations in Females | Mean estradiol concentrations were assessed according to the DELFIA (registered trademark) assay. The lower limit of quantitation for estradiol is 5 pg/mL and measurements below this limit are given a value of 5 pg/mL. The final visit for measurement estradiol concentrations occurred at a mean age +/- SD of 10.93 +/- 1.27 (range, 5.59 to 13.24) years. | Baseline, Weeks 4, 12, 24, 48 (Year 1), yearly for 5 years (Week 240), and Final Visit | No |
Secondary | Mean Stimulated Testosterone Concentrations in Males | Mean stimulated testosterone concentrations were assessed according to the DELFIA (registered trademark) assay. The final visit for measurement of testosterone occurred at a mean age +/- SD of 12.34 +/- 1.16 (range, 11.14 to 14.07) years. | Baseline, Weeks 4, 12, 24, 48 (Year 1), yearly for 5 years (Week 240), and Final Visit | No |
Secondary | Mean Ratio of Bone Age to Chronological Age | Bone age was determined by radiography of the wrist according to the Fels Method. The mean ratio of bone age to chronological age provides information about the slowing of bone age progression. A score = 1 indicates that bone age is equal to chronological age. | Week 24 and Week 48 (Year 1), yearly for 5 years (Week 240), and Final Visit | No |
