Real-World Clinical Experience of Oral Semaglutide in a Secondary Diabetes Clinic in the UK: A Retrospective Observational Study.

ABSTRACT

INTRODUCTION: Oral semaglutide improves cardiovascular risk factors in people with type 2 diabetes (T2D) in clinical trials, though real-world evidence is limited. We aimed to determine the real-world impact of oral semaglutide on routinely collected clinical data in our practice. METHODS: People with T2D initiated on oral semaglutide in secondary care diabetes clinics at two hospital sites in Wales (United Kingdom) were included. Data were collected on reasons for oral semaglutide initiation and changes in bodyweight, blood pressure, glycemic control, and lipid profiles over follow-up at 3-6 months, and at 6-12 months. Data were collected to determine the safety of oral semaglutide. RESULTS: Seventy-six patients were included, with a median age 59.3 [51.4-67.6] years, and 38 (50.0%) patients were female. The most common reasons for oral semaglutide were need for weight loss and improved glycemia (69.8%), and improved glycemia alone (25.0%). Oral semaglutide associated with significantly reduced bodyweight (- 3.3 kg), body mass index (BMI) (- 0.9 kg/m2), glycated hemoglobin (HbA1c) (- 11 mmol/mol), and total cholesterol (- 0.4 mmol/l) by 3-6 months follow-up. At 6-12 months, there was a significant reduction in systolic blood pressure (- 7.0 mmHg), in addition to sustained reductions in other metabolic parameters. By 12 months, 18 (23.6%) patients had discontinued the drug, largely resulting from gastrointestinal disturbance, but there were no serious events in this cohort. CONCLUSIONS: Oral semaglutide was effective in improving cardiovascular risk factors in this real-world population living with T2D, and no serious events were identified related to oral semaglutide in this patient group.
