Glycemic efficacy and safety of the SGLT2 inhibitor ertugliflozin in patients with type 2 diabetes and stage 3 chronic kidney disease: an analysis from the VERTIS CV randomized trial

Abstract

INTRODUCTION: Here we report the glycemic efficacy and safety of ertugliflozin in patients in the VERTIS CV cardiovascular outcome trial with chronic kidney disease (CKD) stage 3. RESEARCH DESIGN AND METHODS: at screening. The primary endpoint was glycemic efficacy at week 18. Longer term glycemic efficacy and changes in body weight, systolic blood pressure (SBP), and eGFR were also evaluated. RESULTS: ). Week 18 least squares (LS)-mean (95% CI) placebo-adjusted changes from baseline in glycated hemoglobin (HbA1c) for 5 mg and 15 mg ertugliflozin were -0.27% (-0.37% to -0.17%) and -0.28% (-0.38% to -0.17%), respectively, for CKD stage 3 overall and -0.27% (-0.38% to -0.15%) and -0.31% (-0.43% to -0.19%), respectively, for CKD stage 3A (all p<0.001). For CKD stage 3B, the reduction in HbA1c for 5 mg ertugliflozin was -0.28% (-0.47% to -0.08%) (p=0.006) and for 15 mg ertugliflozin was -0.19% (-0.39% to 0.01%) (p=0.064). LS-mean placebo-adjusted reductions in body weight (range: -1.32 to -1.95 kg) and SBP (range: -2.42 to -3.41 mm Hg) were observed across CKD stage 3 categories with ertugliflozin. After an initial dip, eGFR remained above or near baseline with ertugliflozin treatment. The incidence of overall adverse events (AEs), symptomatic hypoglycemia, hypovolemia, and kidney-related AEs did not differ between ertugliflozin and placebo across CKD stage 3 subgroups. CONCLUSIONS: In VERTIS CV patients with CKD stage 3A, ertugliflozin resulted in reductions in HbA1c, body weight and SBP, maintenance of eGFR, and was generally well tolerated. Results in the CKD stage 3B subgroup were generally similar except for an attenuated HbA1c response with the 15 mg dose. TRIAL REGISTRATION NUMBER: NCT01986881.
