Overview
This observational study aims to assess the effect of once-weekly s.c. semaglutide 2.4 mg as an adjunct to a calorie-reduced diet and increased physical activity on weight loss, change in hunger, body composition, depression, and quality of life after 68 weeks of treatment in adolescents diagnosed with monogenic obesity in routine clinical care.
Description
The primary objective of this prospective, non-interventional observational study is to evaluate the effect of once-weekly s.c. semaglutide 2.4 mg in routine clinical care as an adjunct to a calorie-reduced diet and increased physical activity on weight loss after 68 weeks of treatment in adolescents diagnosed with monogenic obesity.
The secondary objectives of this prospective, non-interventional observation are to evaluate treatment compliance and to assess the influence of once-weekly s.c. semaglutide 2.4 mg in clinical practice on hunger score, body mass parameters, body composition, and depression score after 68 weeks of treatment in adolescents diagnosed with monogenic obesity. In addition, we will document the known parameters of safety and tolerability to determine safety and tolerability in clinical practice.
The exploratory objective of this prospective, non-interventional observation is to assess user satisfaction by measuring change in subjective hunger score, quality of life, and perceptions and attitudes regarding treatment with semaglutide in adolescents diagnosed with monogenic obesity treated in routine clinical practice with once-weekly s.c. semaglutide 2.4 mg after 68 weeks of treatment.
