AIMS: The once-weekly administered glucagon-like peptide 1 (GLP-1) receptor agonist (GLP-1RA) semaglutide, has, in clinical trials, demonstrated significant reductions in glycated haemoglobin A(HbA) and body weight in persons with type 2 diabetes. We evaluated the real-world clinical effects of semaglutide once weekly in a hospital-based diabetes out-patient clinic. 1c1c
METHODS: This retrospective observational cohort study included persons with type 2 diabetes (n = 119) on a broad range of antidiabetic medicine: GLP-1RA naïve persons (n = 37) and GLP-1RA-experienced persons (n = 82). Person characteristics at inclusion: age [median (quartiles)]: 65 (57, 72) years; body weight 99 (86, 118) kg; body mass index (BMI) 33 (29, 38) kg/m²; HbA61 (54, 69) mmol/mol/(7.7 (7.1, 8.5) %). Data were collected at baseline and after 3, 6 and 12 months of semaglutide treatment. Data were analysed using a general linear mixed model for repeated measurements. 1c
RESULTS: After 12 months, the reductions in HbAwere (mean [95% confidence interval]: GLP-1RA naïve: -12.8 [-17.0, -8.5] mmol/mol/ -1.2 [-1.6, -0.8]% (p < 0.01) and GLP-1RA experienced: -6.4 [-9.0, -3.8] mmol/mol/ -0.6 [-0.8, -0.4]% (p < 0.01), respectively. Body weight reductions in GLP-1RA naïve: -5 [-6.9, -3.1] kg (p < 0.01) and GLP-1RA experienced: -3.2 [-4.4, -2.0] kg (p < 0.01), respectively. Seventy-five percent received 1 mg QW semaglutide. 1c
CONCLUSION: We observed effects of semaglutide once weekly on HbAand body weight comparable with the effects observed in clinical studies with fewer persons in our cohort receiving maximum dose of semaglutide. 1c
