Abstract OBJECTIVES: Anti-vascular endothelial growth factor (VEGF) therapy restores retinal architecture and enhances vision in diabetic macular edema (DME). Bevacizumab is an off-label anti-VEGF drug that effectively treats DME. The safety and efficacy of bevacizumab biosimilars, which are more affordable than the original medication, still need to be established. This study aimed to assess the cost-effectiveness, efficacy, and safety of biosimilars for treating patients with naïve DME across various price ranges that are accessible in the Indian market. MATERIALS AND METHODS: Two biosimilars, BevaciRelTM (Reliance Life Sciences Pvt. Ltd.) and ZyBev (Cadila Healthcare Limited), were compared to their original, Avastin (Roche Products India Pvt. Ltd.), in a randomized, control study. Three end-notes were used to assess safety and efficacy: persistence, improvement, and adverse events. Cost-effective analysis was carried out using a decision-tree analysis model. RESULTS: This study included 69 (59%) men and 54 (41%) women with naïve DME. The cohort had an average log MAR visual acuity of 0.87 ± 0.22, and the central retinal thickness at baseline on OCT was 398.5 ± 37.61 μm. The visual acuity showed a similar improvement, and there was a decrease in central retinal thickness as observed on OCT across the groups. The incremental cost-effectiveness ratio was 10.8. CONCLUSIONS: The biosimilars of bevacizumab are safe and efficacious in treating DME in a cost-effective manner.
