Outcome Measures
Primary Outcomes (1)
Percentage of Participants With Suppression of Peak-Stimulated Luteinizing Hormone
Luteinizing Hormone (LH) suppression is defined as peak-stimulated LH \< 4 mIU/mL. Peak-stimulated LH refers to the maximum LH concentration measured 30 and 60 minutes after a gonadotropin-releasing hormone agonist (GnRHa) stimulation test. Participants who failed suppression at previous visit and prematurely discontinued were counted as having failed future visits also. Final visit is the participant's last visit closest to Month 36.
Day 1, Months 6, 12, 24, and 36
Secondary Outcomes (8)
Percentage of Female Participants With Suppression of Basal Estradiol (Assay 1)
Day 1, Months 3, 6, 9, 12, and 24
Percentage of Female Participants With Suppression of Basal Estradiol (Assay 2)
Months 6, 9, 12, 24, 30, and 36
Percentage of Male Participants With Suppression of Basal Testosterone
Day 1, Months 3, 6, 9, 12, 24, 30, and 36
Mean Peak-stimulated Luteinizing Hormone Concentration by Visit
Baseline of the lead-in study L-CP07-167, Day 1, Months 6, 12, 24, and 36
Percentage of Female Participants With Suppression of the Physical Signs of Puberty (Breast Development)
Baseline (of the lead-in study L-CP07-167), Day 1, Months 3, 6, 9, 12, 18, 24, 30, and 36
- +3 more secondary outcomes

Interventions
Eligibility Criteria
You may qualify if:
- Subject completed the Treatment Period of the lead-in study, L-CP07-167 (NCT00635817), and has documented luteinizing hormone suppression as evidenced by peak-stimulated luteinizing hormone \<4 mIU/mL at the Month 6 study visit of the lead-in study.
- Demonstrated suppression of the physical signs of puberty at Month 6 of the lead-in study.
- Subject is expected to receive at least 12 months of therapy to treat Central Precocious Puberty after study entry.
- In general good health with no uncontrolled, clinically significant disease which would interfere with bone maturation or mask the objectives of this protocol as assessed by the investigator.
You may not qualify if:
- Incomplete precocious puberty, peripheral precocious puberty or evidence of any abnormal pituitary, hypothalamic, adrenal, thyroid and gonadal function (other than premature secretion of gonadotropins) not adequately controlled, unstable intracranial tumors except hamartoma.
- Bone age ≥14 years for girls and ≥15 years for boys (based on the Month 6 lead in study, L-CP07-167, radiographic results).
- Has an abnormal laboratory value suggesting a clinically significant underlying disease or condition.
- Chronic illness requiring treatment that may interfere with growth, ie, chronic steroid use, renal failure, moderate to severe scoliosis.
- Current therapy with medroxyprogesterone acetate.
- Current therapy with growth hormone.
- Current therapy with insulin-like growth factor-1 (IGF-1).
- Current use of an estrogen preparation.
- Any concomitant medical condition that, in the opinion of the investigator, may expose a subject to an unacceptable level of safety risk or that affects subject compliance.
- Subject has a positive pregnancy test.
