Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A double-blinded, randomised, placebo-controlled trial of semaglutide 3.0 mg/ml in patients with poor weight-loss following bariatric surgery. The primary aim of this trial is to determine whether, and the extent to which, 68 weeks of subcutaneous semaglutide 3.0 mg/ml causes greater percentage weight loss (%WL), reduction in adiposity, improvement in metabolic and inflammatory indices and health-related quality of life (HRQoL) than placebo, in patients with poor weight loss following gastric bypass or sleeve gastrectomy.
