Summary
This study tested the drug somatropin (a growth hormone) in 33 Japanese people with Prader-Willi syndrome, a genetic condition that causes weak muscles, slow growth, and constant hunger. The goal was to see if somatropin could safely improve body composition by increasing lean muscle mass and reducing fat. Participants received the drug for 12 months, and changes were measured using body scans.
