Summary

This study tests a drug called vosoritide in 100 children with idiopathic short stature (short height with no known cause). The goal is to see if vosoritide can safely improve growth compared to standard growth hormone. Participants will receive either vosoritide or growth hormone, and their height and growth rate will be tracked over time.
