简要总结
The present randomized trial was initially intended to study the benefits of a combined treatment with growth hormone (GH) and a gonadotropin-releasing hormone (GnRH) agonist for pubertal children with idiopathic short stature. However, treatments were stopped in January 2012 at the request of the French drug agency. Therefore, a protocol amendment divided the study in two study periods.
Study Period 1 involved combined treatment with somatropin and leuprorelin or treatment with somatropin alone. Participants from France who participated in this Period 1 of the study were asked to participate in a long term safety follow up defined as a Period 2 of the study. Participants from the Netherlands were offered participation in Genetics and Neuroendocrinology of Short Stature International Study (GeNeSIS, clinicaltrials.gov Identifier: NCT01088412) for long term safety follow up independent of this study.

结局指标
主要结局
Number of Participants With One or More Drug-related Adverse Events
时间窗: Baseline through End of Study (up to 9 years)
A drug-related AE was an AE that occurred postdose or was present predose and became more severe postdose and was considered to be related to study treatment. A summary of other nonserious AEs, and all SAE's, regardless of causality, is located in the Reported Adverse Events section.
Adult Height Standard Deviation Score (SDS)
时间窗: Baseline through End of Study (up to 9 years)
The height of the participants were measured barefoot using a standard wall-mounted Harpenden stadiometer. SDS report the number of standard deviations from the mean for age and sex for an individual measurement (normal range: -2 to +2 SDS). Height SDS is derived by subtracting the population mean from individual's height value and then dividing that difference by the population standard deviation. Greater height SDS values indicate greater height.
次要结局
- Difference Between Adult Height SDS and Target Height SDS(Baseline through End of Study (up to 9 years))
- Height SDS(Baseline through End of Study (up to 9 years))
- Difference Between Adult Height SDS and Baseline Height SDS(Baseline through End up Study (up to 9 years))
- Percentage of Children With Normal Adult Height SDS(Baseline through End of Study (up to 9 years))
- Height Velocity(Baseline through End of Study (up to 9 years))
- Bone Age(Baseline through End of Study (up to 9 years))
- Difference Between Adult Height SDS and Baseline Predicted Height SDS(Baseline through End up Study (up to 9 years))
