Effects of once-weekly dulaglutide on kidney function in patients with type 2 diabetes in phase II and III clinical trials.

Dulaglutide is a once-weekly glucagon-like peptide-1 receptor agonist approved for the treatment of type 2 diabetes (T2D). Integrated data from 9 phase II and III trials in people with T2D (N = 6005) were used to evaluate the effects of dulaglutide on estimated glomerular filtration rate (eGFR [Chronic Kidney Disease Epidemiology Collaboration]), urine albumin-to-creatinine ratio (UACR) and kidney adverse events (AEs). No significant differences in eGFR were observed during treatment for dulaglutide vs placebo, active comparators or insulin glargine (mean +/- standard deviation values: dulaglutide vs placebo: 87.8 +/- 17.7 vs 88.2 +/- 17.9 mL/ min/1.73 m(2), P =.075; dulaglutide vs active comparators: 89.9 +/- 16.7 vs 88.8 +/- 16.3 mL/ min/1.73 m(2), P =.223; and dulaglutide vs insulin glargine: 85.9 +/- 18.2 vs 83.9 +/- 18.6 mL/ min/1.73 m(2), P =.423). Lower UACR values were observed for dulaglutide vs placebo, active comparators and insulin glargine (at 26 weeks, median [Q1-Q3] values were: dulaglutide vs placebo: 8.0 [4.4-20.4] vs 8.0 [4.4-23.9] mg/g, P =.023; dulaglutide vs active comparators: 8.0 [4.4-21.2] vs 8.9 [4.4-27.4] mg/g, P =.013; and dulaglutide vs insulin glargine: 8.9 [4.4-29.2] vs 12.4 [5.3-50.5] mg/g, P =.029). AEs reflecting potential acute renal failure were 3.4, 1.7 and 7.0 events/1000 patient-years for dulaglutide, active comparators and placebo, respectively. In conclusion, dulaglutide treatment of clinical trial participants with T2D did not affect eGFR and slightly decreased albuminuria.
