In EMPA-REG OUTCOME, empagliflozin (EMPA) reduced the risk of CV death by 38% in T2D patients (pts) with CV disease. EMPA induces an initial, reversible dip in estimated glomerular filtration rate (eGFR). We investigated whether this transient initial renal hemodynamic effect was influenced by baseline characteristics or had an impact on the EMPA-induced risk reduction in CV death. In a post-hoc analysis, among the 6,668 pts randomized to EMPA 10 mg, 25 mg or placebo [PBO] with eGFR available, 28.3% of EMPA pts vs. 13.4% PBO experienced an initial eGFR decline >10% from baseline to Week 4 (odds ratio [OR; 95% CI]: 2.7 [2.3-3.0]). Multivariate logistic regression was used to identify baseline characteristics predictive of eGFR dip >10%. The impact of an eGFR dip >10% on the risk reduction in CV death was assessed using Cox regression. Diuretic use and higher KDIGO (Kidney Disease: Improving Global Outcomes) risk category at baseline were predictive of an eGFR dip >10% with EMPA vs. PBO. Serious adverse events were generally lower or similar in EMPA vs. PBO, regardless of predictive baseline factors. EMPA-induced CV death risk reduction was consistent across subgroups below vs. above average eGFR dipping OR (Panel A) and not affected by eGFR dip >10% (Panel B). T2D pts with more advanced kidney disease and/or on diuretic therapy were more likely to experience an eGFR dip >10% with EMPA. EMPA reduced CV death, regardless of an initial eGFR dip >10%.
