What the trial is, and whether it could suit you
This is a two-part clinical study for children with growth hormone deficiency. In the first part, participants will be randomly assigned to receive different doses of an oral treatment (GS3-007a dry suspension) or a placebo for 14 days. This part is double-blinded, meaning neither the participants nor the doctors will know who is receiving the treatment or placebo. The goal is to find a safe and well-tolerated dose.
In the second part, participants will be randomly assigned to receive either the selected dose of GS3-007a or another approved treatment for 52 weeks. This part is open-label, so everyone will know which treatment is being given. After that, all participants may continue taking GS3-007a for another 156 weeks in an extension phase to study long-term effects.
