Efficacy and safety of empagliflozin in combination with other oral hypoglycemic agents in patients with type 2 diabetes mellitus.

Introduction: To analyze the efficacy and safety of empagliflozin combined with other oral hypoglycemic agents in patients with type 2 diabetes mellitus.

Methods: Pooled analysis of three phase III trials in patients with type 2 diabetes mellitus (n=1,801) who received placebo or empagliflozin 10 or 25mg once daily for 24 weeks, in combination with metformin, metformin+sulphonylurea or pioglitazone ± metformin.

Results: Empagliflozin significantly decreased HbA1c (adjusted mean reduction vs placebo with empagliflozin 10mg: -0.58% [95% CI: -0.66; -0.49]; P<.0001, and with empagliflozin 25mg: -0.62% [95% CI: -0.70; -0.53], P<.0001), weight (adjusted mean reduction vs placebo with empagliflozin 10mg: -1.77kg [95% CI: -2.05; -1.48]; P<.0001, and with empagliflozin 25mg: -1.96kg [95% CI: -2.24; -1.67], P<.0001), and systolic and diastolic blood pressure (SBP/DBP). Adverse effect rates were 64% with placebo, 63.9% with empagliflozin 10mg, and 60.9% with empagliflozin 25mg. Documented episodes of hypoglycemia (≤70mg/dL and/or requiring care) occurred in 3.9% of patients with placebo, 6.9% of patients with empagliflozin 10mg, and 5.3% of patients with empagliflozin 25mg. Urinary tract infections developed in 9.4% of patients with placebo, 10.2% of patients with empagliflozin 10mg, and 8.3% of patients with empagliflozin 25mg. Genital infections were reported in 1.0% of patients with placebo, 4.6% of patients with empagliflozin 10mg, and 3.5% of patients with empagliflozin 25mg.

Conclusions: Empagliflozin combined with other oral treatments decreased HbA1c, body weight, and SBP/DBP as compared to placebo, with a good safety and tolerability profile.
