RESETTLE Trial (ECO 2026 May 13): Semaglutide 2.4 mg in 18-28 Year Olds With Treatment-Resistant Severe Obesity Drives 19% Mean BMI Reduction
Prof. Jens-Christian Holm and colleagues at the Children's Obesity Clinic (European Centre for Obesity Management at Holbæk Hospital) presented RESETTLE at ECO 2026 on May 13. The randomized trial enrolled young adults aged 18-28 who remained severely obese despite at least one year of hospital-based non-pharmacological treatment in childhood. After 68 weeks of once-weekly semaglutide 2.4 mg vs placebo, the treatment arm achieved 19% mean BMI reduction (22.3 kg average weight loss). Total fat mass, abdominal fat, and liver fat all improved substantially vs placebo. The data fills a clinical gap — most semaglutide weight-loss trials excluded young adults coming out of structured pediatric obesity programs, leaving prescribers without evidence for one of the most underserved cohorts.
