Abstract
INTRODUCTION The study aimed to evaluate comparability in terms of efficacy, safety and immunogenicity of Sun's ranibizumab biosimilar with reference ranibizumab in patients with neovascular age-related macular degeneration (nAMD). METHODS This prospective, randomised, double-blind, two-group, parallel-arm, multicentre, phase 3 comparative study included patients with nAMD ≥ 50 years, randomised (in a 2:1 ratio) in a double-blind manner to receive 0.5 mg (0.05 mL) intravitreal injection of either Sun's ranibizumab or reference ranibizumab in the study eye every 4 weeks until week 16 (total of four doses). RESULTS Primary endpoint results demonstrated equivalence in the proportion of patients who lost fewer than 15 letters from baseline best-corrected visual acuity (BCVA) to the end of week 16 (99% of patients in Sun's ranibizumab and 100% in reference ranibizumab; p > 0.9999), with the proportional difference (90% confidence interval) at -1% (-2.51, +0.61) lying within a pre-specified equivalence margin. Visual acuity improved by 15 or more letters in 43% of Sun's ranibizumab group and 37% of the reference ranibizumab group (p = 0.4267). The mean increase in BCVA was 15.7 letters in Sun's ranibizumab group and 14.6 letters in the reference ranibizumab group (p < 0.001 within both groups and p = 0.5275 between groups). The mean change in central macular thickness was comparable between groups (p = 0.7946). Anti-ranibizumab antibodies were found in one patient of the reference ranibizumab group, while neutralising antibodies were not found in any patients. Both products were well tolerated. CONCLUSION Sun's ranibizumab biosimilar is found to be therapeutically equivalent to reference ranibizumab in patients with nAMD. There were no additional safety or immunogenicity concerns.

Abstract
Purpose To report the incidence, clinical features, potential risk factors, and outcomes of intraocular inflammation (IOI) following brolucizumab in Indian eyes. Methods All consecutive patients diagnosed with brolucizumab-induced IOI from 10 centers in eastern India between October 2020 and April 2022 were included. Results Of 758 injections given during the study period across centers, 13 IOI events (1.7%) were recorded attributable to brolucizumab. The IOI occurred after the first dose in two eyes (15%) (median 45 days after brolucizumab), second dose in six eyes (46%) (median = 8.5 days), and third dose (39%) in the remaining five eyes (median 7 days). Reinjections of brolucizumab were administered at a median interval of 6 weeks (interquartile range = 4-10 weeks) in the 11 eyes, where IOI occurred after the second or third dose. Eyes that experienced IOI after the third dose had received a significantly greater number of previous antivascular endothelial growth factor injections (median = 8) compared to those who developed it after the first or second dose (median = 4) (P = 0.001). Anterior chamber cells were seen in almost all eyes (n = 11, 85%), while peripheral retinal hemorrhages were seen in two eyes, and one eye showed branch artery occlusion. Two-thirds of patients (n = 8, 62%) recovered with a combination of topical and oral steroids, while remaining recovered with topical steroids alone. Irreversible visual loss was not seen in any eye, and median vision recovered to pre-IOI levels by 3 months' time point. Conclusion Brolucizumab-induced IOI was relatively rare, occurring in 1.7% of eyes, was more common after the second or third injection, especially in those who required frequent reinjections every 6 weeks, and occurred earlier with increasing number of previous brolucizumab injections. Continued surveillance is necessary even after repeated doses of brolucizumab.

Abstract
Purpose To analyse outcomes of innovator ranibizumab (IRM) (Lucentis) and biosimilar ranibizumab (BRM) (Razumab) in Indian eyes with neovascular age-related macular degeneration (nAMD). Methods Retrospective observational study in nAMD patients, who were treated with IRM or BRM (3 loading doses followed by pro re nata (PRN). Primary outcome measures were change in best corrected visual acuity (BCVA) and central macular thickness (CMT) along with safety analysis. Secondary outcomes measures were changes in the subretinal fluid (SRF) and intraretinal fluid (IRF). Results Inclusion criteria were satisfied in 164 eyes (60.74%). A total of 87 eyes were treated with IRM, and 77 eyes received BRM. Baseline BCVA was 0.57±0.27 logMAR in IRM group and 0.61±0.25 in the BRM group. At 3, 6, 9, and 12 months BCVA was 0.27±0.22 (p<0.0001), 0.34±0.23 (p<0.0001), 0.39±0.25 (p<0.0001), and 12 months 0.41±0.23 (p<0.0001) in the IRM group and 0.24±0.16 (p<0.0001), 0.27±0.16 (p<0.0001), 0.34±0.17 (p<0.0001), 0.38±0.18 (p<0.0001) in the BRM group. Baseline CMT was 420.39±54.45 μm in IRM group and 407.82±53.07 μm in BRM group. At 3, 6, 9, and 12 months, CMT decreased to 258.28±20.4 μm (p<0.0001), 268.38±19.5 μm (p<0.0001), 269.51±32.41 μm (p<0.0001), and 278.28±16.56 μm (p<0.0001) in the IRM group and 258.84±17.47 μm (p<0.0001), 265.69±17.29 μm (p<0.0001), 273.64±23.13 μm (p<0.0001), and 283.09±19.66 μm (p<0.0001) in the BRM group. Similar improvements in IRF and SRF levels in the patients were noted in both groups. Required number of doses of IRM and BRM was similar over the 12 month period in both groups. A similar profile of adverse events was noted in both the groups. Conclusion Intravitreal injection of IRM and BRM show similar efficacy and safety in Indian eyes with nAMD.

Abstract
Introduction To compare the efficacy of innovator ranibizumab (iRBZ—Accentrix, Novartis, India) vs. biosimilar ranibizumab (bRBZ, Razumab-Intas, India) in eyes with diabetic macular edema (DME) in an Indian population. Methods Data of patients with DME who underwent at least three injections of iRBZ or bRBZ and had a minimum of 6 months follow-up were obtained from an electronic database. Choice of injection depended upon the patient. Pro re nata (PRN) protocol from baseline was used with reinjections advised if the central macular thickness (CMT) was at least 300 μm and best corrected visual acuity (BCVA) was 20/40 or worse. Primary outcome measure was comparison of change in BCVA at 6 months between iRBZ and bRBZ. Results We included 264 eyes in the iRBZ group and 69 eyes in bRBZ group, which were comparable for baseline characteristics. Mean BCVA improved from 0.64 ± 0.39 logMAR to 0.47 ± 0.31 logMAR (p < 0.001) in the iRBZ group and from 0.71 ± 0.42 logMAR to 0.50 ± 0.29 logMAR in the bRBZ group (p < 0.001) at 6 months. There were no differences in BCVA between the two groups (p > 0.05 for all time points). The CMT reduction in the iRBZ group (120 ± 196 µm) was comparable to that in the bRBZ group at 6 months (105 ± 187 µm) (p = 0.69). There was no difference in the mean number of injections taken (3.81 ± 1.2 in iRBZ vs. 3.55 ± 1.2 in bRBZ) (p > 0.05) between groups. Vision at baseline was the only factor associated with vision at last follow-up after adjusting for CMT at baseline, type of injection, and number of injections. Conclusions Biosimilar RBZ is similar to innovator RBZ in improving vision and reducing CMT in eyes with DME in the short term.

Abstract
Ranibizumab is approved for the treatment of several macular disorders, including wet age-related macular degeneration (wet AMD), diabetic macular edema (DME), retinal vein occlusion (RVO) and myopic choroidal neovascularization (mCNV), among others. The unaffordability of the innovator ranibizumab among patients from developing countries such as India led to the development of the world’s first biosimilar ranibizumab, which is a cost-effective alternative that does not compromise efficacy and safety. Razumab™, developed and produced by Intas Pharmaceuticals Ltd., India, is the world’s first biosimilar of ranibizumab, and is approved in India for the treatment of various macular disorders, including wet AMD, DME, RVO and mCNV. The efficacy and safety of Razumab for the treatment of these macular disorders have been evaluated in both prospective and real-world retrospective studies. Razumab has shown an efficacy similar to that of the innovator ranibizumab, achieving improved visual acuity, as measured by the best corrected visual acuity, and reduction in the central macular thickness, leading to improved patient outcomes. The safety profile of Razumab is comparable to that of the innovator ranibizumab and is well tolerated without any new safety concerns. Here, we review the clinical and real-world data of Razumab in the treatment of macular disorders.
