Efficacy and Safety of Empagliflozin in Renal Transplant Recipients With Posttransplant Diabetes Mellitus
Abstract
OBJECTIVE: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have lately become the recommended treatment in patients with type 2 diabetes and high cardiovascular risk. Patients with posttransplant diabetes mellitus (PTDM) also have high cardiovascular risk. The aim of this study was to investigate the safety and efficacy of empagliflozin in renal transplant recipients with PTDM.
RESEARCH DESIGN AND METHODS: Forty-nine renal transplant recipients were included in an investigator-initiated, single-center, prospective, double-blind study and randomized to receive either 10 mg empagliflozin or placebo once daily for 24 weeks. Patients transplanted >1 year ago, diagnosed with PTDM, with stable renal function (estimated glomerular filtration rate [eGFR] >30 mL/min/1.73 m2), and with stable immunosuppressive therapy were studied.
RESULTS: Forty-four renal transplant recipients (22 empagliflozin/22 placebo, 34 males) completed the study. Median (interquartile range) change in glycated hemoglobin (HbA1c) was significantly reduced with empagliflozin compared with placebo: -0.2% (-0.6, -0.1) (-2.0 mmol/mol [-6.5, -1.0]) vs. 0.1% (-0.1, 0.4) (1.0 mmol/mol [-0.75, 3.8]) (P = 0.025). The magnitude of glucose reduction was dependent on GFR and baseline HbA1c. The treatment also resulted in a significant reduction in body weight of -2.5 kg (-4.0, -0.05) compared with an increase of 1.0 kg (0.0, 2.0) in the placebo group (P = 0.014). There were no significant differences between the groups…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
