A Phase 2 Study of Vosoritide in Children With Idiopathic Short Stature

Following a minimum 6 month observational period in which baseline growth is assessed, participants in the vosoritide and placebo groups will complete a minimum of 6 months of randomized treatment (maximum of 6 months of placebo treatment), followed by open-label treatment with vosoritide until they reach near-final adult height, or at least 16 years of age for females or 18 years of age for males, whichever comes later. Participants randomized to the hGH group will receive open-label hGH for a minimum of 4 years.
