Objective

DAPA-CKD demonstrated risk reduction for kidney and cardiovascular outcomes with dapagliflozin versus placebo in participants with chronic kidney disease (CKD) with and without diabetes. We compared outcomes according to baseline glycemic status.

Research Design and Methods

We enrolled participants with CKD, estimated glomerular filtration rate (eGFR)
25–75ml/min/1.73m²and urinary albumin-to-creatinine ratio 200–5000mg/g. The primary composite endpoint was sustained eGFR decline ≥50%, end-stage kidney disease, or kidney or cardiovascular death.

Results

Of 4304 participants, 738 had normoglycemia, 660 pre-diabetes, and 2906 type 2 diabetes. The effect of dapagliflozin on the primary outcome was consistent (p-interaction=0.19) in normoglycemia (HR [95%CI] 0.62 [0.39–1.01]), pre-diabetes (HR 0.37 [0.21–0.66]) and type 2 diabetes (HR 0.64 [0.52–0.79]). We found no evidence for effect modification on any outcome. Adverse events were similar, with no major hypoglycemia or ketoacidosis in participants with normoglycemia or pre-diabetes.

Conclusions

Dapagliflozin safely reduced kidney and cardiovascular events independent of baseline glycemic status.
