Summary
This study tracks the long-term safety and effectiveness of the growth hormone treatment Growtropin-II in children with short stature. It includes up to 5,000 children with growth hormone deficiency, idiopathic short stature, Turner syndrome, or those born small for gestational age. Researchers will monitor side effects and changes in height over time to see how well the treatment works in real-world use.
