JOULE - Metabolic Adaptation to Weight Loss in Response to a Behavioural Lifestyle Program With or Without Semaglutide in Adolescents With Obesity

Semaglutide will be delivered by a subcutaneous injection using an injectable pen once weekly. Semaglutide is formulated with 5 approved doses (0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg). Treatment will commence with the lowest dose and will be increased every 4 weeks to the maximum tolerable dose where they will remain for the remainder of the treatment. Participants who are taking the drug will have monthly visits to assess any adverse events, dose titration and drug adherence.

The BLP will be delivered by the Growing Healthy Weight Management (GHWM) pediatric program at McMaster Children's Hospital. GHWM is a family-based program addressing health behaviours (nutritional pattern and eating behaviours, physical activity, sedentary time and sleep) and physical and mental health issues. In Year 1, the program typically includes 2 group sessions and monthly individualized sessions with the participant and their family. The interdisciplinary weight management team is comprised of a registered dietician, exercise physiologist, kinesiologist, social worker and/or psychologist, general pediatrician and pediatric endocrinologists.
