title: Real-world effectiveness and safety of dapagliflozin therapy added to a GLP1 receptor agonist in patients with type 2 diabetes.
abstract: To evaluate the effectiveness and safety of a sodium-glucose cotransporter-2 (SGLT-2) inhibitor, dapagliflozin, in patients with type 2 diabetes mellitus (T2DM) and background glucagon-like peptide-1 receptor agonist (GLP1-RA) therapy.
  
  
  
  This is a 12-month, real-world observational study, which assessed the effectiveness and safety of dapagliflozin in patients with T2DM and background GLP1-RA therapy. The main outcome measures were changes in A1C and weight at 6 and 12 months from baseline. Secondary outcomes were differences in A1C and weight reduction between this cohort and another group of patients with T2DM treated with dapagliflozin but without background GLP1-RA therapy. In total, 109 patients with GLP1-RA and 104 patients without GLP1-RA were included. Baseline mean A1C and weight in the GLP1-RA and non-GLP1-RA groups were 7.4% vs. 7.3% and 96.2 kg vs. 95.1 kg, respectively. A significant reduction in A1C was seen with dapagliflozin in both cohorts at 6 and 12 months (GLP1-RA: -0.51% and -0.34%, non-GLP1-RA: -0.69% and -0.62%, respectively, p < 0.0001 in all analyses). Weight was significantly reduced in both groups at 6 and 12 months (GLP1-RA: -2.3 kg and -2.4 kg, non-GLP1-RA: -3.9 kg and -4.8 kg, respectively, p < 0.0001 in all analyses). A1C reduction and weight loss were significantly lower in patients with GLP1-RA than in patients without GLP1-RAs. Drug discontinuation rates were similar in both cohorts.
  
  
  
  Dapagliflozin, when added in real life to patients with T2DM treated with GLP1-RAs, induced a further significant, albeit modest improvement in A1C and a further weight loss.
