Background: Increases in measured inulin clearance, measured creatinine clearance, and estimated glomerular filtration rate (eGFR) have been observed with bardoxolone methyl in 7 studies enrolling approximately 2,600 patients with type 2 diabetes (T2D) and chronic kidney disease (CKD). The largest of these studies was Bardoxolone Methyl Evaluation in Patients with Chronic Kidney Disease and Type 2 Diabetes (BEACON), a multinational, randomized, double-blind, placebo-controlled phase 3 trial which enrolled patients with T2D and CKD stage 4. The BEACON trial was terminated after preliminary analyses showed that patients randomized to bardoxolone methyl experienced significantly higher rates of heart failure events. We performed post-hoc analyses to characterize changes in kidney function induced by bardoxolone methyl. Methods: Patients in ­BEACON (n = 2,185) were randomized 1: 1 to receive once-daily bardoxolone methyl (20 mg) or placebo. We compared the effects of bardoxolone methyl and placebo on a post-hoc composite renal endpoint consisting of ≥30% decline from baseline in eGFR, eGFR <15 mL/min/1.73 m2, and end-stage renal disease (ESRD) events (provision of dialysis or kidney transplantation). Results: Consistent with prior studies, patients randomized to bardoxolone methyl experienced mean increases in eGFR that were sustained through study week 48. Moreover, increases in eGFR from baseline were sustained 4 weeks after cessation of treatment. Patients randomized to bardoxolone methyl were significantly less likely to experience the composite renal endpoint (hazards ratio 0.48 [95% CI 0.36–0.64]; p < 0.0001). Conclusions: Bardoxolone methyl preserves kidney function and may delay the onset of ESRD in patients with T2D and stage 4 CKD.

Extracellular superoxide dismutase 3 (SOD3), one member of the antioxidant defense system and a superoxide scavenger, has been noted to be downregulated in the kidneys of diabetic mice and is characterized by a heparin-binding domain that can anchor the protein to the endothelium and extracellular matrix. The association of the serum and urinary SOD3 levels with diabetic nephropathy in different stages has never been evaluated. It remains unclear how urinary SOD3 changes in different renal diseases. We recruited 98 Taiwanese patients with type 2 diabetes and 10 patients with early chronic kidney disease (CKD) into this study. Biochemical analyses were performed, including evaluation of the serum SOD3, urinary SOD3, urinary albumin, urinary vascular endothelial growth factor (VEGF), and urinary angiotensinogen (ANG). The Kruskal-Wallis rank sum test was used to compare various parameters among the three groups of patients: early CKD, diabetes alone, and diabetes with CKD. Results showed that lower serum and urinary SOD3 levels were observed in the group of patients with diabetes alone. Higher serum and urinary SOD3 levels were observed in the group of patients with diabetes and CKD, which had higher albuminuria and serum creatinine levels. The serum SOD3 levels were significantly positively correlated with renal function, according to the serum creatinine level. The urinary levels of SOD3 were significantly correlated with other urinary biomarkers such as urinary ANG and VEGF. Furthermore, albuminuria can positively predict the serum SOD3 level for the ratio of urinary albumin to urinary creatinine (ACR) >1,190.769 mg/g and the urinary SOD3 level for ACR ≥300 mg/g.

Abstract Background and Aims Reductions in albuminuria are consistently associated with a subsequent lower risk of kidney failure. The sodium glucose co-transporter 2 inhibitor dapagliflozin significantly reduced albuminuria in patients with type 2 diabetes. Whether this effect persist in patients with chronic kidney disease (CKD) with and without diabetes is unknown. We therefore assessed and compared the effects of dapagliflozin on albuminuria in patients with CKD with and without type 2 diabetes from the DAPA-CKD trial. Method We randomized 4304 patients with CKD and an eGFR of 25-75 ml/min/1.73m2 and urinary albumin-to-creatinine ratio (UACR) 200-5000 mg/g to dapagliflozin (10 mg once daily) or placebo. Change in albuminuria was a pre-specified exploratory outcome. We used regression in UACR stage, defined as a transition from macroalbuminuria (≥300 mg/g) to micro- or normoalbuminuria (&lt;300 mg/g), and progression in UACR stage, defined as a transition from non-nephrotic (&lt;3000 mg/g) to nephrotic range albuminuria (≥3000 mg/g), as additional endpoints. Subgroup analyses were performed according to baseline type 2 diabetes status. Results Median (25th to 75th Percentile) UACR was 949 (477-1885) mg/g. In patients with and without type 2 diabetes baseline median UACR was 1017 mg/g and 861 mg/g, respectively. Dapagliflozin, compared to placebo, reduced UACR by 29.3% (95% confidence interval [CI] 25.2, 33.1; p&lt;0.001), with a 35.1% (95%CI 30.6, 39.4) reduction in patients with type 2 diabetes and 14.8% (95%CI 5.9, 22.9) reduction in patients without type 2 diabetes (p for interaction &lt;0.001). Among 3860 patients with UACR ≥300 mg/g at baseline, dapagliflozin significantly increased the likelihood of regression in UACR stage (hazard ratio [HR] 1.81; 95%CI 1.60, 2.05). The corresponding HRs for patients with and without type 2 diabetes were 2.06 (95%CI 1.78, 2.39) and 1.33 (95%CI 1.07, 1.66), respectively (p for interaction 0.001). Among 3820 patients with UACR &lt;3000 mg/g at baseline, dapagliflozin significantly decreased the risk of nephrotic range albuminuria (HR 0.41; 95%CI 0.32, 0.52). The corresponding HRs for patients with and without type 2 diabetes were 0.39 (95%CI 0.29, 0.51) and 0.50 (95%CI 0.30, 0.82), respectively (p for interaction 0.401). Conclusion In patients with CKD with and without type 2 diabetes dapagliflozin significantly reduced albuminuria, with a larger reduction in patients with type 2 diabetes. The similar effects of dapagliflozin on clinical outcomes in patients with or without type 2 diabetes, but different effects on UACR suggest that part of dapagliflozin’s protective effect in patients without diabetes is mediated through pathways unrelated to UACR reduction.
