No substantially different relative risk for kidney failure among three Anti-VEGF Drugs, finds study

This study was conducted by Cai CX and colleagues. Anti-VEGF drugs are a mainstay in the treatment of several eye diseases, including diabetic retinopathy, age-related macular degeneration, and retinal vein occlusion. However, concerns have been raised regarding their potential systemic effects, particularly on renal function. This study sought to address whether there were differences in kidney failure risk among these drugs.

The retrospective cohort study analyzed data from over 240,000 adult patients who received intravitreal anti-VEGF medications for various eye conditions. The study focused on patients who had received at least 3 monthly treatments and were newly treated with anti-VEGF agents. The primary outcome assessed was the incidence of kidney failure among patients treated with aflibercept, ranibizumab, and bevacizumab.

The key findings of the study were as follows:

• The study found no substantially different relative risk for kidney failure among the three anti-VEGF drugs.

• The hazard ratios for kidney failure were similar across comparisons: 1.01 for aflibercept versus ranibizumab, 0.95 for ranibizumab versus bevacizumab, and 0.95 for aflibercept versus bevacizumab.

• The safety profile of all three drugs was consistent, with no serious or severe treatment-emergent adverse events reported.

• The most commonly reported adverse events were somnolence and dizziness.

• While all three drugs are effective for treating eye diseases, there are differences in cost.

• Bevacizumab, although off-label, was found to be significantly cheaper compared to aflibercept and ranibizumab.

The study provides reassurance to clinicians regarding the safety of anti-VEGF drugs concerning kidney failure risk. The findings suggest that clinicians can choose these drugs based on other factors, such as efficacy and cost, without concerns about differential renal risks. Further research may be needed to explore the long-term effects of these drugs on renal function.
