Summary

This study looks at whether a once-weekly injection of semaglutide (2.4 mg) can help teenagers with monogenic obesity lose weight and feel better. About 70 teens aged 12 to 20 will take the drug along with diet and exercise changes for 68 weeks. The main goal is to see if at least 10% of their body mass index (BMI) drops, and to track changes in hunger, body composition, mood, and quality of life.
