INTRODUCTION: Clinical trials have demonstrated greater glycemic control and weight loss with once-weekly (OW) semaglutide versus other anti-diabetes medications, including sodium-glucose co-transporter 2 inhibitors (SGLT2is) in adults with type 2 diabetes (T2D), yet real-world evidence is limited.
METHODS: This observational study of adults with uncontrolled T2D (HbA1c ≥ 7.0%) initiating semaglutide OW or SGLT2is (January 2018-February 2022; first prescription = index) utilized linked data from IQVIA PharMetrics® Plus adjudicated claims and Ambulatory Electronic Medical Records databases. Among the all semaglutide OW cohort and subgroups (1: persistent [≤ 60-day gap in semaglutide OW supply]; 2: receiving maximum dose ≥ 1 mg; and 3: persistent and ≥ 1 mg dose), changes in weight, body mass index (BMI), and glycated hemoglobin (HbA1c) outcomes from baseline to 1 year post index were descriptively compared. For the main analysis, changes in weight, BMI, HbA1c, and all-cause healthcare resource utilization (HCRU) after 1 year were compared among adjusted semaglutide OW and comparator SGLT2i cohorts, following inverse probability of treatment weighting (IPTW).
RESULTS: The all semaglutide OW cohort included 772 patients, and IPTW adjusted cohorts included 416 semaglutide OW patients and 1093 SGLT2i patients. Significant (P < 0.0001) mean changes from baseline were observed in the all semaglutide OW cohort and all subgroups, in weight (kg [all: - 4.4; 1: - 5.0; 2: - 4.9; 3: - 5.2]), BMI (kg/m[all: - 1.5; 1: - 1.8; 2: - 1.8; 3: - 1.9]), and HbA1c (% [all: - 1.5; 1: - 1.7; 2: - 1.5; 3: - 1.6]). Post-IPTW adjustment, the semaglutide OW cohort had significantly greater mean reductions versus the SGLT2i cohort in weight (- 4.4 versus - 3.4 kg, P = 0.0061), BMI (- 1.5 versus - 1.1 kg/m, P = 0.0013), and HbA1c (- 1.6 versus - 1.2%, P < 0.0001), with similar all-cause HCRU. 2 2
CONCLUSION: Adults with T2D initiating semaglutide OW in the real-world had significant decreases in weight, BMI, and HbA1c after 1 year, with greater improvements versus SGLT2i, and similar HCRU.
