Real-World Safety Outcomes of Intravitreal Ranibizumab Biosimilar (Razumab) Therapy for Chorioretinal Diseases.

ABSTRACT:

Introduction

To assess the safety profile of the intravitreal ranibizumab biosimilar molecule, Razumab^® (Intas Pharmaceuticals, Ahmedabad, India) in chorioretinal disorders under real-world conditions.

Methods

This was a multicenter, retrospective chart review which included patients from 15 centers receiving intravitreal Razumab (IVRz) injections from 2016 to 2020. Patient demographics, ocular examination data, and detailed safety information regarding serious adverse events (SAE) or serious adverse drug reactions (sADR), and non-serious AEs (nsAE) or non-serious ADRs (nsADR) occurring within 1 month of IVRz injections were compiled.

Results

A total of 6404 eyes of 6404 patients received 9406 IVRz injections [mean (± SD) = 1.49 (± 0.63)] during 4.25 years. Adverse events were reported after 1978 injections (21.03%): 64.16% nsAE, 32.96% nsADR, 2.37% sADR, and 0.51% SAE. The most frequent adverse events were subconjunctival hemorrhage (8.2% of total injections), transient blurring of vision (6.5% of total injections), and mild ocular pain (5.27% of total injections). Serious ocular (31 cases with retinal pigment epithelial tears [0.33%], two cases of non-infectious vitritis [0.02%], and one case of endophthalmitis [0.01%]) and systemic (seven patients with non-fatal myocardial infarction [0.12%] and six patients with non-fatal cerebrovascular accident [0.09%]) adverse events were infrequent.

Conclusion

The study reports the largest pooled safety data on IVRz use in a real-world scenario. The results did not raise any new ocular or systemic safety concerns for the biosimilar agent, with the incidence and spectrum of adverse reactions similar to those reported with other anti-vascular endothelial growth factor (anti-VEGF) drugs. The real-world evidence suggests that IVRz is a safe anti-VEGF agent in the management of chorioretinal disorders.

Project description:PurposeTo evaluate the effectiveness, safety, and treatment patterns of ranibizumab 0.5 mg in prior ranibizumab-treated patients with neovascular age-related macular degeneration (nAMD) enrolled in the LUMINOUS™ study.Patients and methodsLUMINOUS, a 5-year, prospective, multicenter, observational study, recruited 30,138 adult patients (treatment-naïve or prior ranibizumab-treated or other ocular treatments) across all approved indications for ranibizumab. Patients were treated as per local ranibizumab label of participating countries. Here we report the mean change in visual acuity (VA) at Year 1, treatment exposure, overall incidence of ocular, non-ocular adverse events (AEs) and serious AEs (SAEs) in prior ranibizumab-treated nAMD patients (n = 16,167).ResultsAt baseline, the mean (standard deviation [SD]) age of patients was 78.4 (9.0) years, 59.0% were female, and 80.0% were Caucasian. At Year 1 (n = 10,168), the mean (SD) VA change was -1.6 (12.6) letters (baseline VA: 58.3 [19.0] letters) with a mean (SD) of 4.7 (3.1) ranibizumab injections. Stratified by duration of prior ranibizumab treatment of <1 (n = 4,112), 1 to <2 (n = 2,095), 2 to <3 (n = 1,506), 3 to <4 (n = 1,123), 4 to <5 (n = 689), and ≥5 (n = 256) years, the mean (SD) VA change at Year 1 were -1.2 (13.5), -2.0 (12.3), -2.0 (11.3), -1.9 (11.8), -2.5 (10.9), and 0.0 (11.2) letters, respectively. Mean (SD) VA change in patients who received ≤6 and >6 injections over 1 year was -1.8 (13.8) and +0.5 (12.5) letters, respectively. The rate of ocular/non-ocular AEs and SAEs across all prior ranibizumab-treated patients over 5 years were 13.29%/23.02% and 0.84%/13.66%, respectively.ConclusionsOverall, regardless of the prior ranibizumab-treatment duration, VA was maintained in these patients at Year 1, and those receiving ≥6 injections showed a trend towards gaining letters. There were no new safety signals. These results may help inform routine clinical practice to appropriately treat nAMD patients with ranibizumab to achieve optimal visual outcomes.
