Weekly shot could replace daily needles for short stature kids
NCT ID NCT07226089
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if a once-weekly injection of somatrogon works as well as a daily growth hormone shot for children with short stature. It includes 254 children born small for their age or with no clear cause for their short height. The goal is to see if the weekly option can improve height just as much, with fewer injections.
