ABSTRACT
Background: Neovascular age-related macular degeneration (nAMD), also known as wet AMD, is a chronic eye disease that affects the macula, which is the central part of the retina responsible for sharp, central vision. Brolucizumab is a type of anti-vascular endothelial growth factor (VEGF) drug, which works by blocking the activity of a protein called VEGF that promotes the growth of abnormal blood vessels under the macula in neovascular AMD. The aim of this study was to evaluate the clinical outcome of brolucizumab in the treatment of neovascular age-related macular degeneration. Material & Methods: This prospective observational study was conducted in Department of Ophthalmology, Bangladesh Eye Hospital & Institute Ltd, Dhaka, Bangladesh, during the period from February 2022 to February 2023. Total 60 patients with neovascular AMD were included in this study who were treated with brolucizumab. Results: The mean age of the patients was 74.3 (SD±9.8) years. Majority of the study subjects were (51.7%) female patients in the study. In our study, majority (38.3%) of the patients had only their right eye affected. In optical coherence tomography (OCT) findings, we found that a high percentage of patients had subretinal fluid (85%), intraretinal fluid (61.7%), and sub-RPE fluid (83.3%). The BCVA showed a significant change after 12 weeks of treatment, as indicated by the P-value of 0.0007. Here improvement of vision was seen in patients with AMD with active Choroidal neovascularization (CNV). But in case of AMD with macular scar, no improvement of vision was seen. In addition, the SRT, FCP, and CMT parameters also showed a statistically significant (P<0.001) improvement after brolucizumab treatment. In our study, 4 patients (6.7%) experienced intraocular inflammation, which is inflammation within the eye, 2 patients (3.3%) reported cloudy vision, and 3 patients (5%) experienced eye redness as a complication of the treatment. The majority of the patients, 51 (85%) did not experience any complications from the treatment. After treatment, improved vision was seen in most of the study patients (70%) and 30% had no improvement. Conclusion: From the findings of our study, it can be concluded that brolucizumab may be an effective treatment for neovascular AMD, as it can improve the best-corrected visual acuity and structural outcomes of the retina such as subfoveal retinal thickness, foveal center point, and central macular thickness. There was also a tolerable complication rate after treatment.
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
Polypoidal choroidal vasculopathy (PCV) occurs in the middle-aged and elderly population and is characterized by abnormal intrachoroidal vascular patterns such as branching choroidal vascular networks and polypoidal dilatation of vessel terminals, subretinal orange nodular lesions and hemorrhagic or plasma retinal pigment epithelial detachment (PED), which can cause retinal hemorrhage or vitreous hematopoiesis and is one of the major blinding fundus lesions.Intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs is currently the main method of PCV treatment, and has certain advantages in eliminating abnormal vascular networks and removing polypoidal lesions, reducing vascular exudation and promoting exudate absorption, and improving visual prognosis.However, frequent intravitreal drug injections increase the risk of infection and the treatment burden for patients.In addition, the high recurrence rate after treatment poses a significant challenge to clinical practice, so the search for new therapeutic agents that are durable and less costly is a focus of clinical research in PCV.The literature from abroad suggests that brolucizumab is a novel small-molecule anti-VEGF humanized monoclonal antibody with the advantages of high tissue penetration, high local drug concentration and bioavailability, small injectable dose, long-lasting efficacy and long injection interval, which brings new hope for the clinical treatment of PCV and improving the prognosis of affected eyes.Although the efficacy and safety of brolucizumab in the treatment of PCV have been well documented, the literature is mainly from Japan, India and Korea, and clinical practice data from China are still lacking.With the approval of the drug in several countries, it is believed that more PCV patients could benefit from this treatment in the near future.Ophthalmologists and researchers in China should closely follow the progress of brolucizumab in the treatment of PCV.

Purpose: To report the initial experience of managing treatment?resistant and treatment?na飗e eyes with polypoidal choroidal vasculopathy (PCV) by using brolucizumab 6 mg. Methods: This was a retrospective multicentric series of all consecutive eyes with PCV treated with brolucizumab. Treatment resistance was defined as taking at least six prior anti?VEGF injections over the past 1 year and showing persistent disease activity in the form of intra (IRF) or subretinal fluid (SRF) or both. All patients were treated on a pro re nata (PRN) basis and followed up monthly. Retreatment was considered when either SRF or IRF were present at any time point during the study. Results: We included 21 eyes of 21 patients with PCV with a mean age of 65.1 � 9.9 years, of which 16 eyes (76%) were treatment?resistant. The mean follow?up period from receiving the first brolucizumab was 27.3 � 3.3 weeks. Of the 21 eyes, seven eyes (33%) received three injections during follow?up, 13 eyes (62%) received two injections, and one eye received one injection. The mean injection?free interval was 12 � 1.2 weeks. The median pretreatment vision was 0.6 logMAR (IQR = 0.47�logMAR) and improved to 0.3 logMAR (IQR = 0.25�6 logMAR), whereas the mean macular thickness improved from 443 � 60 ?m at baseline to 289 � 25 ?m (P < 0.001) at the last follow?up period. None of the eyes experienced any intraocular inflammation across 48 injection sessions. Conclusion: Brolucizumab is safe and effective in controlling PCV disease in both treatment?resistant and treatment?na飗e eyes
ABSTRACT
Diabetic macular edema(DME)has become the leading cause of vision loss in patients with diabetes. Currently, intravitreal injection of anti-vascular endothelial growth factor(VEGF)therapy is the first-line treatment for DME. However, the economic burden and related complications brought by frequent injections should not be ignored. Therefore, the drugs with longer-lasting effects and longer injection intervals must be explored. Brolucizumab is a single-chain antibody fragment(scFv)with a high affinity for VEGF. Compared with other available anti-VEGFs, it has the characteristics of smaller molecular weight, higher tissue permeability and durable therapeutic effect. Clinical studies and real-world evidences showed that Brolucizumab is non-inferior to aflibercept in improving visual acuity in patients with DME. And Brolucizumab is more effective in regressing intra-retinal fluid and reducing central foveal thickness(CSFT)with longer injection interval. At the same time, Brolucizumab has a low incidence of adverse events and favourable safety after intraocular injection. This article reviews the latest progress of Brolucizumab in the treatment of DME.
ABSTRACT
@#Anti-vascular endothelial growth factor(anti-VEGF)drugs have become the first choice for the treatment of intraocular neovascularization, but the inconvenience and possible complications caused by frequent intravitreal injection cannot be ignored. Therefore, it is necessary to seek new drugs with long-lasting effects, so as to reduce the number of injections. Brolucizumab, a novel small molecule anti-VEGF drug, has the advantages of stronger tissue penetration, higher drug concentration, smaller injection dose, long-lasting efficacy and longer injection interval. Registered clinical studies and real-world evidence showed that Brolucizumab is non-inferior to aflibercept in efficacy, while its ability to improve intraretinal/subretinal fluid is more significant, and it can maintain a longer dosing interval. In addition, Brolucizumab is safe and has a low incidence of serious adverse events, such as retinal vasculitis reported. Brolucizumab provides a new treatment option for neovascular age-related macular degeneration(nARMD). This article reviews the latest progress of Brolucizumab in the treatment of nARMD.
