1197-P: Two-Year Effects of Ertugliflozin on Renal Function

Abstract

2 RCT evaluating ertugliflozin 5 mg (E5, n=652), 15 mg (E15, n=640) vs. non-ertugliflozin (NE, glimepiride or placebo, n=644) in T2D patients were pooled to evaluate effects on eGFR (MDRD) and albuminuria (UACR, geometric mean of % change from baseline). eGFR and UACR were analyzed by mixed model repeated measures with treatment, time, trial, baseline measures [A1C, SBP, eGFR/UACR] as covariates in overall population and by presence of UACR >30 mg/g. Baseline characteristics in the treatment groups were balanced. Overall, mean baseline eGFR was 88.2 ml/min/1.73m2 and geometric mean baseline UACR was 11.6 mg/g. At week 6, changes in eGFR were: -2.3, -2.7 and -0.7 ml/min/1.73m2, for the E5, E15 and NE groups, respectively. Mean eGFR with ertugliflozin increased over time, while it decreased in the NE group. The week 104 ΔeGFR [95% CI] compared to NE was 1.81 ([0.13, 3.49]; p=0.04) and 2.10 ml/min/1.73m2 ([0.42, 3.78]; p=0.01) for E5 and E15, respectively. In patients with baseline UACR > 30 mg/g (n=415) the ertugliflozin groups had greater UACR reductions. The week 104 ΔUACR [95% CI] compared to NE was -29.0% ([-47.0, -4.5]; p=0.02) for E5 and -32.7% ([-50.4, -8.6]; p=0.01) for E15. Ertugliflozin acutely reduced eGFR in an expected fashion, possibly based of known hemodynamic effects. Over 104 weeks, eGFR values were higher with ertugliflozin than control, suggestive of renal function preservation. Ertugliflozin reduced UACR in subjects with baseline albuminuria. Disclosure D.
