Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).
