Background
Empagliflozin (EMPA) reduces cardiovascular (CV) and renal risk in type 2 diabetes patients with established CV disease. As shown with RAAS blockade, EMPA also causes an acute eGFR decrease after treatment initiation. Although considered hemodynamic and reversible, it needs to be better understood to avoid premature drug discontinuation.
Methods
In EMPA-REG OUTCOME®, 6,668 participants who received at least one dose of study drug and had an eGFR value at both baseline and week 4 were categorized by % acute eGFR change to: >10% decrease, >0% to ≤10% decrease, ≤0% decrease. eGFR over time was analyzed using mixed model repeated measures. Acute renal failure (ARF) incidence was based on investigator-reported adverse events according to the narrow standardized MedDRA query.
Results
As expected, there were more patients with a >10% decrease in EMPA (28.3%) than in PBO (13.4%); however, an acute eGFR drop >30% with EMPA was rare (1.4%). After initial dynamics, long-term eGFR remained stable in all categories on EMPA (Figure). In multivariate regression analyses, KDIGO risk category (elevated UACR/low eGFR) and diuretic use at baseline were independent predictors of an acute eGFR decrease >10% with EMPA. From baseline to week 4, irrespective of the magnitude of the eGFR decrease, overall adverse events (AEs) and serious AEs were similar or lower with EMPA than PBO. ARF was more frequent in patients experiencing an acute eGFR decrease >10% in both groups, however most were reported as ‘renal impairment’. During chronic treatment, overall and renal safety profiles were similar between PBO and all categories on EMPA.
Conclusion
Given the known renal protection with SGLT2 inhibition, our data demonstrate a relatively modest acute eGFR decrease with treatment, less likely to cause discontinuation of this reno-protective therapy.
