[Semaglutide, once weekly GLP-1 receptor agonist (Ozempic®)].

Semaglutide (Ozempic®) is a new once-weekly agonist of glucagon-like peptide-1 receptors (GLP-1 AR) indicated in the treatment of type 2 diabetes (T2D). Phase III clinical trials of the SUSTAIN programme demonstrated both the efficacy and safety of semaglutide in patients with T2D treated by diet and exercise, oral antidiabetic agents or even insulin. Direct and indirect comparative clinical trials showed that semaglutide (subcutaneous 0.5 or 1.0 mg once weekly) exerts a better glucose-lowering activity and a greater weight loss than other GLP-1 AR. Presented as prefilled pens for subcutaneous injection, semaglutide is currently reimbursed in Belgium after failure of antidiabetic therapy including metformin (HbA1c superior to 7,5 % or 58 mmol/mol) in T2D patients with body mass index ? 30 kg/m².
