简要总结
This is an open-label, multi-center, randomized, two-arm parallel, no-treatment group controlled (only for the first 6 months), Phase 3 study in children with ISS. The subjects will be treated with 0.067 milligram/kilogram/day (mg/kg/day) of Saizen®, weight base dose, for 12 months (12 months of treatment in the test group, and 6 months of no treatment and then 6 months of treatment in the control group).

结局指标
主要结局
Change From Baseline in Height Velocity at Month 6 Using Last Observation Carried Forward (LOCF) Method
时间窗: Baseline, Month 6
Baseline height is defined as the last available height measurement before randomization. Baseline height velocity = (\[Baseline height minus height measurement obtained at least 6 months prior\] / 6) \* 12. Height velocity at Month 6 = (\[Month 6 height minus height measurement obtained at least 6 months prior\] / 6) \* 12.
次要结局
- Change From Baseline in Height Velocity at Month 12(Baseline, Month 12)
- Change From Baseline in Height at Month 6 and 12(Baseline, Month 6, Month 12)
- Change From Baseline in Height Standard Deviation Score (SDS) at Month 6 and 12(Baseline, Month 6, Month 12)
- Change From Baseline in Serum Concentration of Insulin-like Growth Factor-I (IGF-I) at Month 6 and 12(Baseline, Month 6, Month 12)
- Change From Baseline in Serum Concentration of Insulin Like Growth Factor Binding Protein-3 (IGFBP-3) at Month 6 and 12(Baseline, Month 6, Month 12)
- Percentage of Adherence to Study Treatment(6 months post-dose (Saizen Test Group and Saizen Control Group); 12 months post-dose (Saizen Test Group))
- Number of Subjects With Treatment Emergent Adverse Events (TEAEs), Serious TEAEs(Baseline up to Month 13)
