Multicenter Interventional Study: Somatrogon Impact on Outcomes in Naive Small for Gestational Age or Idiopathic Short Stature Pediatric Patients Compared With Daily Growth Hormone
This study is a randomized, open-label, active controlled, parallel group study comparing the efficacy and safety of once weekly Somatrogon to daily Growth Hormone (Genotropin) in pre-pubertal children with short stature either born Small for Gestational Age (SGA) or with Idiopathic Short Stature (ISS). The planned study duration is 12 months with a screening period of up to 30 days. The study will consist of two groups: 140 children with SGA who are naïve to GH treatment will be randomized 1:1 to receive either Somatrogon or Genotropin for 12 months. A second group will include 114 children with ISS who are naïve to GH treatment who will be randomized 1:1 to receive either Somatrogon or Genotropin for 12 months.
• Diagnosis of SGA or ISS. SGA, defined as born with a birth weight and/or length \<-2 SDS below the mean for gestational age. ISS, defined as height \< -2 SDS for age and gender without evidence of GHD
• Females aged ≥3 years and \<9 years. Males aged ≥3 years and \<11 years
• Pre-pubertal- Tanner stage 1 for breasts and testes.
• A bone age of not more than chronological age recorded in previous 8 weeks.
• Current height \< -2 SDS for age and gender.
• Participants using hormonal replacement therapy(s) must be on an optimized and stable treatment regimen (hormone levels within normal ranges on screening) for at least three months prior to screening
• Participants who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.
