787-P: Glucose and Weight Outcomes Associated with Oral Semaglutide in the Real-World—Initial Results from the Association of British Clinical Diabetologists’ (ABCD) Audit

Semaglutide is the first glucagon like peptide-1 receptor agonist (GLP1-RA) available in an oral preparation. Weight and HbA1c outcomes with injectable semaglutide in the real-world are well established. The aim of this analysis is to assess weight and HbA1c response to oral semaglutide.

Methods: Data were extracted from the secure online ABCD audit tool. Individuals were included if baseline and follow-up weight and/or HbA1c data were available. Change in HbA1c, body mass index (BMI) and weight from baseline was assessed using a multivariate linear regression model and change in the numbers achieving an endpoint HbA1c≤7.5% [58mmol/mol] were assessed using Chi² tests in Stata 16.

Results: Data were available for 350 individuals with baseline mean±SD HbA1c 9.2%±1.7 [76.6mmol/mol±18.3], weight 101.8kg±21.9, BMI 34.3kg/m²±6.9, median diabetes duration 11years (IQR 6-16) and age 59 years (IQR 51-68); 63.0% were male and 79.7% were white. Median follow-up was 0.5years (IQR 0.3-0.8). Significant reductions in HbA1c of 0.7% (95%CI 0.4, 0.9; P<0.001) [7.4mmol/mol; 95%CI 4.7, 10.0; P<0.001] were observed. Weight decreased by 3.3kg (95%CI 2.3, 4.3; P<0.001) and BMI fell by 1.1kg/m² (95%CI 0.6, 1.6; P<0.001). Twice as many people achieved a HbA1c≤7.5% at follow-up compared to baseline (28.6% [52/182] vs 14.3% [26/182]) - this change was statistically significant (P<0.001).

Conclusion: In the real-world, oral semaglutide is associated with statistically significant and clinically meaningful reductions in HbA1c, weight and BMI. The numbers achieving a HbA1c≤7.5% also increased. In the light of this, further data collection and analysis should be undertaken, including comparisons between oral and injectable GLP1-RAs and analysis of switches between them
