Biosimilar Ranibizumab (Ranieyes) Safety and Efficacy in the Real World: BRESER Study

Purpose: To evaluate the early real-world clinical outcomes regarding the safety and efficacy after administration of a ranibizumab biosimilar (Ranieyes). Methods: This multicenter retrospective uncontrolled observational study incorporated data from 7 centers in India. All patients were treated with at least 1 intravitreal injection of 0.5 mg of ranibizumab biosimilar between July 2022 and July 2023 for various indications. Results: A total of 474 ranibizumab biosimilar injections were given in 268 eyes of 254 patients. Indications were diabetic macular edema (DME) (n = 112), macular neovascularization (MNV) (n = 92), retinal vein occlusion (RVO) (n = 54), cystoid macular edema (n = 4), and proliferative diabetic retinopathy with vitreous hemorrhage (n = 6). The mean logMAR BCVA (±SD) improved significantly from baseline to the last follow-up as follows: DME cases, from 0.77 ± 0.37 (Snellen equivalent, 6/36) to 0.43 ± 0.25 (6/15) (z = -8.0; r = -0.8); MNV cases, from 0.95 ± 0.53 (6/60) to 0.59 ± 0.42 (6/24) (z = -7.1; r = -0.8); RVO cases, from 0.83 ± 0.40 (6/45) to 0.44 ± 0.32 (6/15) (z = -5.5; r = -0.8) (all P < .001). All groups also had a significant improvement in the central subfield thickness (all P < .001). No site reported drug-related adverse events (eg, inflammation, vasculitis, systemic adverse effects). Conclusions: The preliminary real-world data from this limited early series suggest that Ranieyes has clinical efficacy and is safe as a ranibizumab biosimilar across the approved indications.
