A narrative review and international survey. Graefes Arch Clin Exp Ophthalmol 2023; 261:3299-3306. [PMID: 37199802 PMCID: PMC10587024 DOI: 10.1007/s00417-023-06108-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 05/02/2023] [Accepted: 05/08/2023] [Indexed: 05/19/2023] Open
Abstract
PURPOSE This study reviews evidence and provides recommendations for the ideal setting of intravitreal injection (IVI) administration of vascular endothelial growth factor (VEGF) inhibitors. METHODS A multi-step approach was employed, including content analysis of regulations and guidelines, a systematic literature review, and an international survey assessing perioperative complications and endophthalmitis incidence in relation to injection settings. The literature review searched PubMed and Cochrane databases from 2006 to 2022, focusing on studies reporting correlations between complications and treatment settings. The survey utilized a web-based questionnaire distributed to clinical sites and the international ophthalmic community, with data managed using electronic capture tools. RESULTS We reviewed regulations and guidelines from 23 countries across five continents, finding significant variation in IVI administration settings. In most countries, IVI is primarily administered in outpatient clean rooms (96%) or offices (39%), while in others, it is restricted to ambulatory surgery rooms or hospital-based operating theatres (4%). The literature review found that endophthalmitis risk after IVI is generally low (0.01% to 0.26% per procedure), with no significant difference between office-based and operating room settings. The international survey (20 centers, 96,624 anti-VEGF injections) found low overall incidences of severe perioperative systemic adverse events and endophthalmitis, independent of injection settings. CONCLUSION No significant differences in perioperative complications were observed among various settings, including operating theatres, ambulatory surgery rooms, offices, hospitals, or extra-hospital environments. Choosing the appropriate clinical setting can optimize patient management, potentially increasing effectiveness, quality, productivity, and capacity.

Abstract
PURPOSE To compare the visual and anatomical outcomes between strict pro re nata (strict PRN) and treat-and-extend (T&E) anti-vascular endothelial growth factor (anti-VEGF) regimens for neovascular age-related macular degeneration (nAMD). METHODS A meta-analysis of 1-year and 2-year changes between strict PRN and T&E anti-VEGF regimens were conducted in both randomized controlled trials (RCTs) and real-world studies (RWSs). The best-corrected visual acuity (BCVA), central retinal thickness (CRT), and weighted mean numbers of visits and injections were evaluated. RESULTS A total of 19 RCTs and 23 RWSs (2,530 eyes in strict PRN and 4,399 eyes in T&E) were included. Mean BCVA change in strict PRN group in both 1-year and 2-year (5.95 and 5.78, respectively) was noninferior to the T&E group (7.85 and 5.96, respectively). Mean CRT changes were also similar in both strict PRN and T&E groups. Mean number of visits were significantly more in the strict PRN group, whereas mean number of injections was significantly more in the T&E group. CONCLUSION The strict PRN regimen demonstrates a noninferior BCVA improvement to the T&E regimen, achieving fewer injections, and may be both economically and medically beneficial. Both selections should be provided to patients with an overall consideration.

Abstract
Age-related macular degeneration (AMD) is a progressive degenerative eye disorder that primarily affects individuals over 50. It causes gradual loss of central vision and can lead to irreversible severe visual loss if left untreated. AMD is a leading cause of blindness in the developed world. This study aimed to investigate the effects of a loading dosage of intravitreal Aflibercept on functional and morphological responses in neovascular AMD, considering demographic characteristics and the link between AMD-related retinal symptoms at presentations. A prospective interventional study was conducted from November 2021 to September 2022 on a sample of Iraqi patients with neovascular AMD who had active choroidal neovascularization (CNV) lesions confirmed by OCT-A and received intravitreal Aflibercept 2mg injection as initial therapy (3 loading doses). Best-corrected visual acuity (BCVA) was used to measure functional responses, and central macular thickness (CMT) and maximum area of the retinal thickness (MART) (by SD-OCT) were used to measure morphological responses. The study included 48 patients (57 eyes) with active neovascular AMD. The mean difference of BCVA in log MAR (0.2 ± 0.7) significantly improved from 1.3±0.7 at baseline to 1.1±0.8 after loading Aflibercept (P=0.034). The mean difference in CMT 113.6 ± 125.9 was statistically significant (P<0.0001). Also, the mean change in MART significantly decreased from 444.2 ± 127.1 µm at baseline to 348.7±74.5 µm (p < 0.0001) after loading Aflibercept. This study demonstrated that Aflibercept is a functionally and anatomically successful treatment for neovascular AMD.

Abstract
OBJECTIVES We sought to identify the consecutive changes and predictive features for exudation recurrence in macular neovascularization (MNV) using optical coherence tomography angiography (OCTA) in type 1 neovascular age-related macular degeneration (NVAMD). METHODS A total of 291 OCTA images in consecutive visit of 45 patients newly diagnosed with type 1 NMV and treated with three loading intravitreal anti-vascular endothelial growth factor injections (IVIs) and a pro-re-nata (PRN) therapy regimen were analysed. Quantitative features of OCTA included the MNV area, MNV length, total number of endpoints (open-ended vessels) and junctions (internal branching) using AngioTool. Two subgroups were divided according to exudation recurrence time from the third IVI (group 1: ≤3 months vs. group 2: >3 months). RESULTS The area, length, number of total junctions, and endpoints decreased during three loading IVIs and increased at exudation recurrence (all p < 0.05). In a subgroup analysis of consecutive OCTA images, the number of total endpoints increased at two months prior to exudate recurrence in group 2 (the late recurrence group, p = 0.020). A higher total number of endpoints of MNV at baseline were found to be related with group 1 (early recurrence, p = 0.020 and 0.012 in univariate and multivariate regression analyses). CONCLUSIONS The MNV with higher open-ended vessels at the lesion periphery at baseline might be expected to show earlier recurrence of exudation after loading IVIs. By observing the number of open-ended vessels in consecutive OCTA images, exudation recurrence could be predicted.

J Manag Care Spec Pharm 2022; 28:1350-1364.

Abstract
BACKGROUND: Brolucizumab is a new anti-vascular endothelial growth factor (anti-VEGF) approved for treating neovascular age-related macular degeneration (nAMD). Multiple treatment regimens are available for treating nAMD. These regimens include manufacturer-recommended regimens, pro re nata (PRN) regimens, and treat-and-extend (T&E) regimens, which are based on clinical practice guidelines and data observed in the real-world clinical setting, classified as real-world evidence (RWE). Most budget impact models predict the financial consequences of adding a new drug to the formulary based on the manufacturer-recommended regimen. With different anti-VEGF treatment regimens being used in nAMD by ophthalmologists, it is OBJECTIVE: To estimate the budget impact of different treatment regimens of brolucizumab in nAMD from a US payer perspective. METHODS: A Microsoft Excel-based budget impact model was developed for different treatment regimens of brolucizumab over a 1-year time frame from a US payer perspective. A separate analysis was performed to estimate the budget impact from a US patient population perspective. Model inputs included drug costs, administration costs, physician visit costs, and disease monitoring costs. Outcomes in the budget impact model included the cost per member per month, annual health plan cost, and the US patient population-based annual cost. Based on the prevalence of nAMD in public and commercial health plans, a scenario analysis was conducted on the US population to account for the differences in the drug cost to the public and commercial payers. Further, 1-way sensitivity analyses were conducted to test model assumptions and uncertainty in model inputs. RESULTS: The addition of brolucizumab to the formulary increased the net budgetary impact under PRN and T&E regimens. The maximum increase in expenditure for a hypothetical health plan with 1 million enrollees was associated with the PRN regimen ($824,696), followed by the T&E regimen ($163,101). In contrast, using the manufacturer-recommended and RWE regimens led to an annual saving of $93,068 and $94,170 for the health plan, respectively. In the US patient population model, the introduction of brolucizumab resulted in savings in the manufacturer-recommended ($30.99 million) and RWE regimens ($31.35 million) but led to an increase in annual expenditures for the PRN ($274.58 million) and T&E ($54.30 million) regimens. CONCLUSIONS: Payers need to evaluate the cost impact of different treatment regimens of existing and new anti-VEGFs when making formulary decisions in nAMD management. DISCLOSURES: Mr Siddiqui, Ms Dhumal, Dr Patel, and Dr LeMasters have nothing to disclose. Dr Kamal has received research funding from Cerevel Therapeutics, served as a consultant to Pfizer/Cytel Inc, and received honoraria from Pharmacy Times Continuing Education. Dr Almony has served as a consultant to Cardinal Health and received honoraria from Pharmacy Times Continuing Education and Prime Education.

Abstract
BACKGROUND Aflibercept is a relatively new anti-VEGF used to treat neovascular age-related macular degeneration (AMD). The purpose of this review is to evaluate the effect of pro re nata (PRN) and fixed regimen (bimonthly) of aflibercept injection for neovascular AMD on visual outcomes at 12 months of follow-up. METHODS We conducted a systematic search in PubMed (MEDLINE), Embase, Scopus, and Web of Science, EBSCOHost, and ClinicalTrials.gov databases. Number of injections, number of hospital visit, mean change of best corrected visual acuity (BCVA), mean change of central macular thickness (CMT), and adverse effects of the included studies were evaluated. Meta-analysis were performed using Review Manager 5.4. RESULTS Four studies were selected for meta-analyses synthesis (3 RCT, 1 retrospective study). A total of 197 eyes in PRN group and 241 eyes in the fixed group. All four studies favored fixed regimen with standardized mean difference of 0.56 (95% CI 0.36-0.75, I2 = 0%, p < 0.00001). There was no significant difference in CMT between both group with SMD of 0.17 (95% CI - 0.14-0.48, I2 = 26%, p = 0.28). CONCLUSION The present meta-analysis shows that bimonthly injection of aflibercept for neovascular AMD is superior compared to PRN injection, shown by better improvement in BCVA at 12 months follow-up. However, high risk of bias downgrade the certainty of evidence.

Abstract
The use of anti-vascular endothelial growth factor (VEGF) agents has profoundly changed the prognosis of neovascular age-related macular degeneration (nAMD). As clinical experiences have accumulated, it has become mandatory to summarize data to give information that can be useful in everyday practice. We conducted a systematic review to identify randomized controlled trials (RCTs) and observational studies that reported 12-month changes in best-corrected visual acuity (BCVA) in patients with nAMD on anti-VEGF monotherapy. Data were analyzed in a random-effects meta-analysis with BCVA change as the primary outcome. Meta-regression was conducted to evaluate the impact of multiple covariates. Four hundred and twelve heterogeneous study populations (109,666 eyes) were included. Anti-VEGFs induced an overall improvement of +5.37 ETDRS letters at 12 months. Meta-regression showed that mean BCVA change was statistically greater for RCTs (p = 0.0032) in comparison with observational studies. Populations following a proactive regimen had better outcomes than those following a reactive treatment regimen. Mean BCVA change was greater in younger populations, with lower baseline BCVA and treated with a higher number of injections (p < 0.001). Our results confirm that anti-VEGFs may produce a significant functional improvement at 12 months in patients with nAMD.

Abstract
Vascular endothelial growth factor (VEGF) has been identified as a major promoter of the development of choroidal neovascularization in age-related macular degeneration. The development of choroidal neovascularization can be slowed by preventing the binding of vascular endothelial growth factor to cellular VEGF receptor-2 present on vascular endothelial cells, which represents the major proangiogenic stimulus. Advances in the development of anti-VEGF therapy have led to significant improvement in visual acuity outcomes in recent years that neovascular age-related macular degeneration can no longer be considered an incurable disease. Despite its many advantages, the current standard of care, which is the frequent application of VEGF blockers to the vitreous, is a significant burden on both the patient and the healthcare system. This review is aim on a new brolucizumab molecule (also known as RTH 258 or formerly ESBA 1008). The article focuses on the molecular aspects of the drug and an overview of the basic preclinical and clinical studies that were performed during drug development. Brolucizumab is a single chain fragment of a humanized monoclonal antibody with a molecular weight of 26 kDa that inhibits VEGF-A. Preclinical animal studies have shown good penetration of the molecule through the retina with minimal systemic exposure. The SEE study (phase 1/2) demonstrated safety and tolerability after drug administration. The OSPREY (phase 2) study demonstrated the same efficacy of brolucizumab on visual acuity in the 8-week dosing regimen compared to aflibercept. In the same study, patients were also pilot tested in a 12-week dosing regimen. The HAWK and HARRIER studies (phase 3) demonstrated the efficacy of the drug at a dose of 6 mg in a 12-week dosing schedule in 55.6 % and 51 % of patients, respectively.

Abstract
Background and objectives: Because few data are available, the aim of this study is to analyze the effects of antithrombotic agents (ATAs) on visual function and long-term risk of cardiovascular events and mortality in hypertensive patients with retinal vein occlusion (RVO). Materials and methods: Hypertensive patients with RVO were consecutively selected from 2008 to 2012 and followed for a median of 8.7 years. Ophthalmologists evaluated and treated RVO complications, and best-corrected visual acuity (BCVA) was checked at each visit during the first one year of follow-up. Survival analysis was conducted on the rate of the composite endpoint of all-cause deaths or non-fatal cardiovascular events. Results: Retrospectively, we collected data from 80 patients (age 68 ± 12 years, 39 males). Central and branch RVO was present in 41 and 39 patients, respectively, and 56 patients started ATAs (50 antiplatelet drugs, 6 warfarin, and 2 low-molecular weight heparin). Average BCVA of the cohort did not change significantly during one-year of follow-up. The only predictor of BCVA was the baseline BCVA value. There was a reduction in proportion and severity of macular edema and an increase in the cumulative proportion of retinal vein patency reestablishment during the follow-up, independent of treatment. ATAs had no effects on one-year BCVA, intraocular complications, or the composite endpoint rate. Conclusions: In this exploratory study, ATAs had no effect on BCVA during the first one year of follow-up and on the composite endpoint during the long-term follow-up. Further prospective studies need to be conducted with an accurate standardization of the intraocular and antithrombotic treatment to define the positive or negative role of ATAs in hypertensive patients with RVO.

Abstract
PURPOSE To determine the dose-response characteristics of the antivascular endothelial growth factor agents ranibizumab and aflibercept in neovascular age-related macular degeneration using published randomized trials and observational series. METHODS Literature review of published series from 2006 to 2018 as determined from electronic searches of PubMed and the Cochrane Library. Data extracted included treatment strategy, frequency, and first year visual acuity response. Monthly or bimonthly treatment schedules were classified as Fixed, pro re nata studies as PRN, treat and extend as TE, and when no strategy was listed, as Variable. RESULTS Of 2062 citations retrieved, 96 were deemed eligible; these 96 citations provided 120 data points of dose frequency versus visual acuity change in Year 1 of treatment. The dose-response curve was nonlinear, but a log transform of the number of injections per year yielded a linear relationship defined by the expression, Letters of Improvement = -6.66 + 15.7*log (number of injections Year 1). After accounting for the number of injections neither the drug used (ranibizumab or aflibercept) nor the strategy used (Fixed, pro re nata, treat and extend, or Variable) were significant predictors of acuity change. As a group, studies using the pro re nata approach had the lowest number of injections and the worst acuity improvements as a treatment strategy. CONCLUSION There seems to be a predictable, mathematically defined relationship between dose frequency and visual acuity change at 1 year in neovascular age-related macular degeneration. The performance of current treatment efforts, as suggested by reported series and Medicare claims data, seems to be substandard.

J Clin Med 2020; 9:jcm9082637. [PMID: 32823822 PMCID: PMC7463565 DOI: 10.3390/jcm9082637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 08/03/2020] [Accepted: 08/11/2020] [Indexed: 11/16/2022] Open
Abstract
Background: The aim of this study was to evaluate outcomes in patients with submacular hemorrhage secondary to polypoidal choroidal vasculopathy (PCV) after switching treatment from a fixed-dose to an as-needed regimen. Methods: This retrospective study included 19 patients with submacular hemorrhage secondary to PCV who were treated with fixed-dose intravitreal aflibercept during the first 56 weeks. After 56 weeks, the treatment regimen was switched to an as-needed regimen. The incidence and timing of lesion reactivation during the as-needed phase were evaluated. The best-corrected visual acuity (BCVA) at baseline (beginning of the regimen) and the final follow-up were compared. Multivariate analysis was performed to determine the factors associated with lesion reactivation. Results: During the mean follow-up period of 27 ± 7.3 months, lesion reactivation was noted in 10 patients (52.6%; mean time period: 12.2 ± 9.1 months) in the as-needed phase. Reactivations were treated with anti-vascular endothelial growth factor (VEGF) injections (mean, 4.1 ± 2.6). The mean logarithm of the minimum angle of resolution (logMAR) BCVA was 0.26 ± 0.34 at baseline and 0.31 ± 0.38 at final follow-up (p = 0.212). Deterioration of ≥0.2 logMAR BCVA was noted in two patients (10.5%). In multivariate analysis, large lesion size was closely associated with a high risk of lesion reactivation (p = 0.009). Conclusion: Visual acuity was relatively stable after switching from a fixed-dose to an as-needed regimen, with no definite visual deterioration in the majority of patients. We conclude that patients with large lesions should be carefully monitored when switching to an as-needed regimen.

Abstract
Background To evaluate the three-year outcome after intravitreal aflibercept injection (IAI) for neovascular age-related macular degeneration (nAMD). Methods Forty-nine treatment-naïve nAMD patients (50 eyes) were enrolled in this prospective study. The eyes received IAI at two-month intervals in the first year. The treatment regimen was changed to IAI based on a treat-and-extend approach in the second and third years. Results Twenty-nine eyes of 28 patients were successfully followed up over 36 months. The nAMD subtypes included 15 eyes with typical AMD and 14 eyes with polypoidal choroidal vasculopathy. The number of IAIs performed over the 3 years was 17.2 ± 3.1 (mean ± standard deviation). The mean logMAR, which was 0.42 at baseline, improved to 0.19 (P = 0.001) at 12 months, and 0.26 (P = 0.049) at 36 months. The central retinal thickness (CRT) was 329 ± 120 μm at baseline, 151 ± 38 μm (P < 0.001) at 12 months, and 143 ± 61 μm (P < 0.001) at 36 months. The mean subfoveal choroidal thickness (SFCT) was 288 ± 97 μm at baseline, 243 ± 82 μm (P < 0.001) at 12 months, and 208 ± 63 μm (P < 0.01) at 36 months. The changes in logMAR, CRT, and SFCT over the study period did not differ between typical AMD and PCV. Conclusion Long-term aflibercept injection can achieve visual improvement and reduce the thickness of the retina and choroid in nAMD. Morphological improvement of these tissues may not be sufficient to sustain earlier visual improvement over the long-term.

A Trinity regimen with aflibercept for treatment-naïve neovascular age-related macular degeneration: 2-year outcomes. Graefes Arch Clin Exp Ophthalmol 2020; 258:1663-1670. [PMID: 32436085 DOI: 10.1007/s00417-020-04745-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Revised: 05/02/2020] [Accepted: 05/08/2020] [Indexed: 10/24/2022] Open
Abstract
PURPOSE To evaluate the advantages of the Trinity regimen for treatment-naïve neovascular age-related macular degeneration (nAMD). METHODS Thirty-one treatment-naïve nAMD eyes were treated using the Trinity regimen with an intravitreal aflibercept injection (IVA) and evaluated after 24 months. Three treatment methods, pro re nata (PRN), treat and extend (TAE), and fixed regimen were changed depending on recurrence frequency. After the initial treatment, PRN or TAE (started for 4 or 8 weeks) was selected as per the recurrence interval. Subsequently, the recurrence interval became constant, transitioning from a TAE to fixed regimen. When the recurrence frequency became irregular, the treatment regimen was changed to TAE. RESULTS After the initial treatment, 15 eyes (48.4%) were allocated to the PRN group, 12 (38.7%) to the TAE 8-week group, and 4 (12.9%) to the TAE 4-week group. Mean logMAR significantly improved in all cases, 0.53 ± 0.40 at baseline to 0.36 ± 0.34 at 24 months (p < 0.01), in the PRN group (0.63 ± 0.46 to 0.42 ± 0.43, p < 0.01), and the TAE 8-week group (0.44 ± 0.29 to 0.27 ± 0.19, p < 0.05). LogMAR in the TAE 4-week group was maintained. The mean number of injections for all and in the PRN, TAE 8-week, and TAE 4-week groups were 9.7, 5.3, 13.1, and 15.8, respectively, with the PRN group being significantly less (p < 0.01). CONCLUSION The Trinity regimen delivered the benefits of the PRN, TAE, and FIXED regimens while minimizing injections during the early treatment phase without visual loss. TRIAL REGISTRATION This trial was registered with the University Hospital Medical Information Network (UMIN ID: 000038335).

Abstract
Purpose: Retinal vein occlusion is associated with an increased risk of cardiovascular diseases. Anti-vascular endothelial growth factor has been widely used as a treatment option. However, the systemic safety of intravitreal anti-vascular endothelial growth factor for retinal vein occlusion patients is still unclear.Materials and Methods: A meta-analysis was conducted to investigate all randomized controlled trials published up to February 2019 of retinal vein occlusion patients who received intravitreal anti-vascular endothelial growth factor vs. control treatments. Fixed effect models were used and results were reported as odds ratios and 95% confidence intervals.Results: Eight trials that evaluated 2320 patients were retrieved. Anti-vascular endothelial growth factor did not significantly increase the risks of cardiovascular events (odds ratio,1.54; 95% confidence interval, 0.66-3.57), hypertension (odds ratio, 0.92; 95% confidence interval, 0.63-1.33), or heart rate disorders (odds ratio,1.53; 95% confidence interval, 0.37-6.28) when compared with control treatment. Subgroup analyses did not show a significant increase of cardiovascular events in aflibercept (odds ratio,1.96; 95% confidence interval, 0.44-8.81) vs. ranibizumab trials (odds ratio, 1.47; 95% confidence interval, 0.54-4.02); 0.5 mg ranibizumab trials (odds ratio, 1.73; 95% confidence interval, 0.61-4.96) vs. 0.3 mg ranibizumab trials (odds ratio, 0.70; 95% confidence interval, 0.14-3.59); nor branch retinal vein occlusion (odds ratio, 1.32; 95% confidence interval, 0.40-4.33) vs. central retinal vein occlusion trials (odds ratio, 1.93; 95% confidence interval, 0.59-6.29).Conclusions: Intravitreal administration of anti-vascular endothelial growth factor did not significantly increase the risks of cardiovascular events, hypertension or heart rate disorders in retinal vein occlusion patients.

Abstract
INTRODUCTION Age-related macular degeneration (AMD) is the most common cause of blindness among the elderly in the industrialized world. While effective treatment is available for neovascular AMD, no therapy is successful for the non-neovascular form. Herein, the authors report the current knowledge on non-neovascular AMD pathogenesis and the promising research on treatments. AREAS COVERED In the present review, the authors summarize the most recent advances in the treatment of non-neovascular AMD and provide an update on current treatment strategies. Evidence available from preclinical and clinical studies and from a selective literature search is reported. EXPERT OPINION When investigating AMD, numerous pathological cascades and alterations of physiological processes have been investigated. It is well-known that AMD is a multifactorial disease, with environmental causes and genetics playing a role. Perturbations in multiple pathogenic pathways have been identified and this led to the development of several molecules directed at specific therapeutic targets. However, despite the huge research effort, the only proven approach so far is oral antioxidant supplementation. We believe that, in addition to successful advancement of promising drugs, further research should be directed at tailoring therapy to specific patient groups, eventually employing a combinational therapy strategy.

Brolucizumab: Evolution through Preclinical and Clinical Studies and the Implications for the Management of Neovascular Age-Related Macular Degeneration. Ophthalmology 2020; 127:963-976.

Abstract
Improving or maintaining visual acuity is the main goal for the treatment of neovascular age-related macular degeneration (nAMD). Current nAMD standard of care dictates frequent intravitreal (IVT) anti-vascular endothelial growth factor (VEGF) injections, which places a substantial burden on patients, caregivers, and physicians. Brolucizumab, a newly developed anti-VEGF molecule for nAMD treatment, has demonstrated longer durability and improvement in visual and anatomic outcomes in clinical studies in a q12-week regimen, indicating its potential to reduce treatment burden as an important therapeutic tool in nAMD management. This review focuses on the development of brolucizumab and the preclinical and clinical studies evaluating its efficacy, tolerability, and safety. Brolucizumab (also known as "RTH258" and "ESBA1008") is a humanized, single-chain variable fragment (scFv) antibody with a molecular mass of approximately 26 kDa that inhibits VEGF-A. Preclinical studies show that brolucizumab readily penetrates the retina to reach the retinal pigment epithelium (RPE)/choroid with minimal subsequent systemic exposure. The safety, tolerability, and efficacy of a single IVT brolucizumab administration in patients with treatment-naïve nAMD were first demonstrated in the SEE Phase 1/2 study. The OSPREY Phase 2 study showed brolucizumab to be as efficacious as aflibercept in a q8-week regimen with regard to best-corrected visual acuity (BCVA) and brolucizumab achieving greater fluid resolution. Brolucizumab-treated patients in the OSPREY study were subsequently challenged with a q12-week dosing interval, and the outcomes provided key information for the study design and end points of the Phase 3 studies. In the HAWK and HARRIER Phase 3 studies, after 3 monthly loading injections, brolucizumab treatment regimen (q12-week or q8-week) was guided by individual disease activity assessment using functional and anatomic parameters (central subfield thickness [CST], intraretinal fluid [IRF], or subretinal fluid [SRF]) versus aflibercept (q8-week). Fewer brolucizumab 6-mg treated eyes had disease activity versus aflibercept, and anatomic outcome results at weeks 16 and 48 demonstrate brolucizumab as a potent drying agent. Moreover, of patients treated with 6 mg brolucizumab, 55.6% and 51.0% maintained a q12-week dosing interval immediately after the loading phase until week 48 in HAWK and HARRIER, respectively. These Phase 3 studies demonstrated that the brolucizumab q12-week regimen maintains efficacy and safety while reducing treatment burden associated with regular IVT injections for patients with nAMD.
