Young Adults With Early-onset Obesity Treated With Semaglutide -The RESETTLE Study
Introduction: The increasing prevalence of obesity is particularly pronounced among adolescents. Currently available treatment options consist of structured lifestyle interventions. However, 25 % of adolescents do not respond to lifestyle treatment, why new effective treatment strategies are needed. Therefore, the aim of this study is to investigate the effect of lifestyle interventions combined with the GLP-1 receptor agonist semaglutide to young adults with otherwise treatment resistant obesity. Methods and analysis: This is an investigator-initiated, randomized, placebo-controlled trial. 180-270 young adults (age 18-28) will be recruited from The Childrens Obesity Clinic (TCOC), Department of Pediatrics, Holbæk Hospital. Based on their previous response to the TCOC protocol the participants will be divided in four groups: Group A: Non-responders: 55-85 young adults with obesity (BMI≥30 kg/m2) who have not reduced adiposity, defined as BMI SDS reduction \<0.1, during the structured lifestyle counselling as children. Group B: Insufficient responders: 55-85 young adults who have reduced adiposity, defined as BMI SDS reduction \>0.25, during the structured lifestyle counselling as children but still have obesity as young adults (BMI≥30 kg/m2) Group C: Excellent responders: 35-50 young adults, who have reduced adiposity, defined as BMI SDS reduction \>0.5, during the structured lifestyle counselling as children and no longer have obesity as young adults (BMI\<30 kg/m2) Group D: Population-based reference group (normal weight development): 35-50 young adults, who have participated in The Holbaek Study as children. Group A and B are randomized 2:1 to either semaglutide or placebo for 68 weeks. Group C and D will attend baseline examinations only and not undergo intervention. The primary endpoint is change in BMI from randomization to end-of-treatment. Ethics and dissemination: The trial has been approved by the Danish Medicines Agency (EudraCT 2019-002274-31) and by the ethical committee of the Capital Region of Denmark (H-20039422). The trial will be conducted in agreement with the Declaration of Helsinki and monitored to follow the guidelines for good clinical practice. Results will be submitted for publication in international peer-reviewed scientific journals.
• Age 18-28 years
• The period from the initial treatment with TCOC protocol until inclusion in the study must be within 15 years.
• Group A: BMI≥30. Non-responders: No BMI SDS reduction (≤0.1 BMI SDS) during TCOC protocol for more than one year and still have obesity.
• Group B: BMI≥30. Insufficient responders: BMI SDS reduction ≥0.25 BMI SDS during TCOC protocol for more than one year, but still have obesity.
• Group C: BMI≤30. Excellent responders: BMI SDS reduction ≥0.5 BMI SDS during TCOC protocol for more than one year and no longer have obesity.
• Group D: Young adults who have participated in The Holbaek Study and have had normal weight development during childhood
