Active clinical trials for "Puberty, Precocious"

The goal of this observational study is to describe the natural history of imprinting disorders (IDs) according to their metabolic profile in all patients (adults and children) affected with an ID regardless of the severity of the disease, with a molecular characterization, with a signed informed consent for all subjects, followed in one partner's center. The main questions it aims to answer are: Can we identify common metabolic profiles for all imprinted diseases? Which imprinting disorders have an impact on the metabolic profiles of IDs? Which are the metabolic risks associated to IDs? Can we use the metabolic profiles for the clinical classification and prognosis of IDs? Are there common therapeutic approaches for all IDs?

The purpose of this study is to explore the genetic basis of reproductive disorders and cleft lip and/or palate.

The primary objective of this study is to determine the safety and efficacy of metformin in lowering serum DHEAS levels in girls with premature pubarche and secondary, to observe changes in hormones associated with pubertal development including gonadotropins, sex steroids, insulin, adipocytokines, and growth factors.

The purpose of this study is to assess long-term safety and efficacy of leuprorelin in the treatment of Central Precocious Puberty (CPP).

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 (GnRH) test performed 3 months after injection of triptorelin.

The purpose of this study is to determine if 11.25 and 30 mg formulations of leuprolide are effective in treating children with Central Precocious Puberty (CPP).

The COPENHAGEN School Study is a combined cross-sectional and longitudinal study of healthy Danish school children. This study will by clinical examinations and withdrawal of blood samples investigate whether age of pubertal onset is continuing to decline in Denmark over the past 15 years. Furthermore, we will investigate the mechanism driving earlier onset of puberty and the long term health risks of extremely early puberty using Danish registry data

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).

A multicenter, open-label, prospective study to evaluate the safety and efficacy of leuprorelin acetate DPS (Leuplin DPS) treatment quarterly in patients with central precocious puberty

Due to various complex factors, the incidence of precocious puberty is increasing rapidly. It severely threatens physical and mental health of children. It's urgent to explore effective ways to control the disease.
