Efficacy of Anti-VEGF Treatments For Diabetic Retinopathy Explored

HealthDay News — Three anti-vascular endothelial growth factor (anti-VEGF) treatments are associated with low rates of diabetic retinopathy (DR) worsening, according to a study published online in JAMA Ophthalmology.
Susan B. Bressler, MD, from Johns Hopkins University, and colleagues conducted preplanned secondary analysis of data from a comparative effectiveness trial for center-involved DME in 650 participants during 2 years of treatment with aflibercept (2 mg), bevacizumab (1.25 mg), or ranibizumab (0.3 mg).
The researchers found that at 1 year, among 423 nonproliferative DR (NPDR) eyes, 44 of 141 (31.2%) treated with aflibercept, 29 of 131 (22.1%) with bevacizumab, and 57of 151 (37.7%) with ranibizumab had improvement of DR severity (P =.004 for aflibercept vs bevacizumab, P =.01 for ranibizumab vs bevacizumab, and P =.51 for aflibercept vs ranibizumab). At 2 years, no treatment group differences were identified. Among the 93 eyes with proliferative DR (PDR) at baseline, 1-year improvement rates were 75.9% for aflibercept, 31.4% for bevacizumab, and 55.2% for ranibizumab (P <.001 for aflibercept vs bevacizumab, P =.09 for ranibizumab vs bevacizumab, and P =.02 for aflibercept vs ranibizumab). These rates and group differences were maintained at 2 years.
“All 3 anti-VEGF treatments were associated with low rates of DR worsening. These data provide additional outcomes that might be considered when choosing an anti-VEGF agent to treat DME,” conclude the authors……
