This study comprises two phases: Phase Ib and Phase II. Phase Ib is a multicenter, randomized, open-label, active-controlled, single-dose, dose-escalation to assess safety, tolerability, PK/PD profile, and immunogenicity of GenSci134 in children with GHD.
Phase II is a multicenter, randomized, open-label, active-controlled, multiple-dose, parallel-group study to assess the efficacy and safety of multiple subcutaneous doses of GenSci134 at different levels versus Norditropin® in children with GHD. It will also evaluate PK/PD profile and immunogenicity to support dose selection for Phase III.
Informed consent of parent or legal representative of participant and child assent, as age appropriate must be obtained before any study-related activities.
