Abstract

Introduction

Despite expert consensus guidelines, data is scarce on how to switch patients with type 2 diabetes when treatment with glucagon-like peptide 1 (GLP-1) receptor agonists is not effective and whether a switch to semaglutide brings any benefit on glucose and weight control for patients with type 2 diabetes.

Methods

Retrospective cohort analysis of patients with type 2 diabetes who were switched from any GLP-1 agonist in a stable dose to subcutaneously administered semaglutide. Primary endpoint was change of glycated haemoglobin (HbA1c) at 6 months. Secondary endpoints were weight, body mass index (BMI), heart rate, blood pressure and adverse events.

Results

In total, 77 patients (median age 65 years) with long-standing type 2 diabetes (median 15 years, median HbA1c 8.4%/68 mmol/l, median BMI 33 kg/m2) were included. HbA1c was significantly lower 6 months after switching to semaglutide (7.3%; 56 mmol/l). Median body weight was significantly lower at 3 months (94 kg) and 6 months (93 kg) compared to baseline (98 kg). An equipotential dose switch of semaglutide was used in 61 patients (79%) and a stepwise initiation approach was used in 16 patients (21%). Both treatment regimens improved glucose control and weight. Side effects occurred in 28 patients (36%).

Conclusion

Switching to semaglutide from established GLP-1 analogue therapy improved HbA1c and body weight. Both equipotential and stepwise dosing initiation appear to be effective and well tolerated.
