Real world effectiveness of oral semaglutide: Focus on patients with type 2 diabetes older than 75 years.

Aim: Data on the efficacy of oral semaglutide (OS) in elderly patients with type 2 diabetes are still lacking. This study evaluates the effectiveness of OS in a real world setting with a large ≥75 year old population.

Methods: This study includes all type 2 diabetic patients who started OS between October 2021 and December 2023 in seven diabetes centers. Data were collected at baseline, 6 (T6) and 12 (T12) months. Effectiveness measures were assessed on the total sample and by patient age (<65, 65-75, >75 years).

Results: Overall 1824 patients started OS, of those 18.7 % were over 75 years (>75 yr). OS resulted in a significant reduction in rate of patients using sulphonylureas, rapid and basal insulin therapy, HbA1c reduced by 0.87 % at T6 and at T12 (both p < 0.0001), body weight by 2.78 Kg (p < 0.0001) at T6 and 3.89 Kg (p < 0.0001) at T12. Similarly, >75 yr showed HbA1c reduction at T6 (p < 0.0001) and T12 (p = 0.0003), body weight significantly reduced (p for interaction 0.005) both at T6 (-1.57 Kg; p = 0.0003) and T12 (-2.74 Kg; p < 0.0001).

Conclusion: In our study, OS results efficacy in non-elderly and elderly patients, making it an effective treatment option also for very elderly type 2 diabetic patients.
