Introduction: The effect of once-weekly (OW) subcutaneous semaglutide, a glucagon-like peptide-1 (GLP-1) analog for the treatment of T2D, has been examined in GLP-1-naïve patients only. Here, we examined glycemic control and weight management in GLP-1-experienced patients switching from another GLP-1 to semaglutide in a real-world setting, using U.S. prescription data.

Methods: Adults (≥18 years old) with T2D were identified in the Explorys (IBM Watson Health) U.S. electronic medical records database (data cut-off 12/5/19). Included patients had ≥1 prescription for semaglutide (index/switch date), a prescription for any other GLP-1 (baseline) in the previous year, and separate HbA1c/weight measurements at 6 or 12 months post-index and in the 90-day pre-index period.

Results: Patients with valid HbA1c (N=365) and weight (N=480) data had similar baseline characteristics. Both the full 6-month cohorts and subgroups with 12-month data had significant HbA1c and weight reductions (Figure). Significant HbA1c improvement at 6 months was sustained at 12 months, whereas weight loss was more pronounced with longer follow-up. HbA1c and weight changes were independent of previous GLP-1 used (p>0.05 between GLP-1s).

Conclusions: Switching to OW semaglutide from another GLP-1 was associated with significant HbA1c and weight reductions in routine clinical practice, independent of previous GLP-1 used.
