The purpose of the protocol is to assess the efficacy of the triptorelin 6 month PR (Prolonged Release) formulation in suppressing LH (Luteinising hormone) levels to prepubertal levels (defined as a peak LH ?5 IU/L) after i.v. GnRH (Gonadotropin-releasing Hormone) stimulation at Month 6 (Day 169) in Chinese children with CPP (Central Precocious Puberty).
The purpose of this study is to observe whether the Triptorelin pamoate 15mg (3-month formulation) effectiveness in Chinese population of CPP children has the same or similar trend with that in overseas CPP population. This is measured by assessing the proportion of children who have a suppressed Luteinizing Hormone (LH) response to Gonadotropin Releasing Hormone
