Real-world use of once-weekly semaglutide in patients with type 2 diabetes: Results from the SURE Switzerland multicentre, prospective, observational study

Aims: SURE Switzerland (NCT03631186) investigated real-world once-weekly (OW) semaglutide use in adults with type 2 diabetes (T2D). Methods: This multicentre, prospective, observational study enrolled adults with T2D with <= 1 documented HbA(1)c value <= 12 weeks before semaglutide initiation. Primary endpoint was change in HbA(1c) from baseline to end of study (EOS; similar to 30 weeks). Secondary endpoints included changes in body weight (BW) and waist circumference (WC), and the proportion of patients achieving HbA(1c) < 8.0%, <7.5% and <7.0% at EOS. Semaglutide dose at EOS was a prespecified exploratory endpoint. Results: Overall, 214 patients initiated semaglutide (baseline HbA(1c) 7.8% [62 mmol/mol], BW 99.9 kg and WC 117.4 cm); 187 attended the EOS visit. At EOS, 175 (81.8%) were still receiving semaglutide (mean [SD] dose 0.78 [0.29] mg); in those patients, mean HbA(1c) reduced by -0.8 [95% CI -1.01;-0.68] %-points (-9 [-11;-7] mmol/mol), BW by -5.0 kg [-5.73;-4.24] and WC by -4.8 cm [-5.75;-3.79] (all p < 0.0001). At EOS, 85.9%, 76.5% and 55.9% patients achieved, respectively, HbA(1c) < 8.0%, <7.5% and < 7.0%. No new safety signals were identified. Conclusions: Patients with T2D in Switzerland initiating OW semaglutide experienced clinically relevant glycaemic control and BW improvements in a real-world setting, supporting semaglutide use in routine clinical practice.
