New hope for short kids: experimental drug takes on growth hormone
NCT ID NCT06382155
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
