Objective: To evaluate real-world clinical outcomes of semaglutide on glycemic control and weight as an add-on to treatment or changed-on from other GLP-1 in patients with T2D who initiate treatment.

Patients and Methods: To better understand the effectiveness of semaglutide on clinical outcomes in a real-world setting, this retrospective cohort study included eligible patients were at least 18 years old with uncontrolled T2D (HbA1c 6.5-11%) receiving stable therapy that initiated subcutaneous semaglutide 0.5 or 1.0 mg once weekly added to their therapy or after a change from other GLP-1. Primary endpoint was change from baseline in glycated Hb (HbA1c) and confirmatory secondary endpoint was change from baseline in body weight, both at week 24. Semaglutide was initiated as part of their diabetes therapy based in clinical practice.

Results: in this study, were included 147 patients had a mean age of 60.3 ± 10.1 years, T2D duration of 14.0 ± 7.4 years, and baseline A1C of 8.3 ± 1.34%. Seventy-five were naïve in treatment with GLP-1 and seventy-four received previously another GLP-1 (liraglutide 1.8 mg daily or dulaglutide 1.5 mg once weekly). At 6 months follow-up, 145 patients who remained on-treatment showed an A1C reduction of 1.2 ± 1.15% (p<0.05), A1C lowering was seen in both groups: a reduction de 1.8±1.8% (p < 0.05) in patients that received GLP for first time and 0.6± 1.0%(p< 0.05) in group prior use of GLP-1. Mean weight reduction was 5.1 ± 4.6 kg (p < 0.001) in the group initiated GLP-1 for first time and 2.1±4.0 kg (p<0.01) in group that changed from another GLP-1. Four patients presented gastrointestinal adverse events to retire the treatment, all of them in the group that never had been treated with GLP-1.

Conclusion: In this real-world study, patients initiating semaglutide had significant reductions in HbA1c and weight. The effect was reached whether patients received GLP-1 for the first time or if a change had been made from another GLP-1.
