Effects of dapagliflozin on development and progression of kidney disease in patients with type 2 diabetes: an analysis from the DECLARE–TIMI 58 randomised trial

Sodium-glucose co-transporter-2 (SGLT2) inhibitors have shown beneficial effects on renal outcomes mainly in patients with established atherosclerotic cardiovascular disease. Here we report analyses of renal outcomes with the SGLT2 inhibitor dapagliflozin in the DECLARE–TIMI 58 cardiovascular outcomes trial, which included patients with type 2 diabetes both with and without established atherosclerotic cardiovascular disease and mostly with preserved renal function. In DECLARE–TIMI 58, patients with type 2 diabetes, HbA1c 6·5–12·0% (47·5–113·1 mmol/mol), with either established atherosclerotic cardiovascular disease or multiple risk factors, and creatinine clearance of at least 60 mL/min were randomly assigned (1:1) to 10 mg dapagliflozin or placebo once daily. A prespecified secondary cardiorenal composite outcome was defined as a sustained decline of at least 40% in estimated glomerular filtration rate [eGFR] to less than 60 mL/min per 1·73m2, end-stage renal disease (defined as dialysis for at least 90 days, kidney transplantation, or confirmed sustained eGFR
