Evaluation of Monthly Leuprorelin Treatment Over 24 Months for Children with Central Precocious Puberty

What this Trial Is About

Researchers are evaluating the safety and effectiveness of a monthly Leuprorelin treatment given for 24 months in children diagnosed with central precocious puberty CPP. This phase 4, single-arm, open-label study focuses on children with early puberty signs, primarily girls younger than 9 years and boys younger than 10 years, who have reached Tanner stage 2 or higher. The study aims to understand how this treatment impacts hormone levels and puberty progression over two years. Participants will receive Leuprorelin injections every four weeks for up to 24 months. This treatment is designed to influence hormone levels by suppressing luteinizing hormone LH after stimulation with gonadotropin-releasing hormone GnRH. The study tracks changes in hormone levels, pubertal development, growth parameters like height and weight, and monitors for any treatment-related adverse events during this period. During the trial, children will undergo regular assessments including hormone tests to measure LH, follicle-stimulating hormone FSH, testosterone, and estradiol levels, as well as evaluations of their pubertal stage and growth. Safety is closely monitored by recording any side effects related to the treatment. The primary outcome is the suppression of peak LH levels 24 weeks after starting treatment, with ongoing follow-ups up to 96 weeks to observe longer-term effects and safety.
