NCT02413138

Brief Summary

The trial will consist of three stages: 1) a 30 day Phase 2 PK and PD evaluation of somavaratan, 2) an optional Phase 2 Extension and 3) a 12 month Phase 3 safety and efficacy stage. Upon completion of the PK/PD stage, the PK/PD profiles for the GHD children in this study will be compared to the PK/PD profiles for the GHD children treated in the Western study Phase 1b/2a study (Protocol 12VR2) and identify the somavaratan dose to be used in the Phase 3 stage in Japan. The Phase 3 stage will continue dosing for 12 months to obtain safety and efficacy data on 48 subjects.
