Takeaway

Why this matters

  • The combined cardio-renal benefits of sodium-glucose cotransporter 2 inhibitors in patients with CKD with and without T2D are substantial, whether there is a history of CVD or not.

Study design

  • In the DAPA-CKD trial, 4304 patients with CKD with and without T2D were randomly assigned to receive dapagliflozin or placebo.

  • In this prespecified subgroup analysis, patients were divided into those with (secondary prevention group, n=1610) and without baseline CVD (primary prevention group, n=2694).

  • Primary outcome: composite of ≥50% decline in estimated glomerular filtration rate, end-stage kidney disease or kidney or CV death.

  • Secondary outcomes: kidney composite outcome (primary endpoint, minus CV death), the composite of hospitalisation for HF or CV death and all-cause death.

  • Funding: AstraZeneca.

Key results

  • Dapagliflozin lowered the risk of the primary composite outcome to a similar extent in both the primary (HR, 0.61; 95% CI, 0.48-0.78) and secondary (HR, 0.61; 95% CI, 0.47-0.79) prevention groups (Pinteraction=.90).

  • Dapagliflozin reduced the risk of the following outcomes to a similar extent in both the primary and secondary prevention groups:

    • composite of HF hospitalisation or CV death (HR, 0.67; 95% CI, 0.40-1.13 and HR, 0.70; 95% CI, 0.52-0.94, respectively; Pinteraction=.88); and

    • all-cause death (HR, 0.63; 95% CI, 0.41-0.98 and HR, 0.70; 95% CI, 0.51-0.95, respectively; Pinteraction=.71).

  • Overall, the rates of adverse events were low and similar in the primary and secondary prevention groups.

Limitations

  • Certain events were infrequent and the effect of therapy on these could not be assessed reliably.
