Phase I DAVIO Trial: EYP-1901 Bioerodible, Sustained-Delivery Vorolanib Insert in Patients With Wet Age-Related Macular Degeneration. OPHTHALMOLOGY SCIENCE 2024; 4:100527. [PMID: 38881599 PMCID: PMC11179418 DOI: 10.1016/j.xops.2024.100527] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 03/15/2024] [Accepted: 04/01/2024] [Indexed: 06/18/2024]
Abstract
Purpose To evaluate safety and tolerability of EYP-1901, an intravitreal insert containing vorolanib, a pan-VEGF receptor inhibitor packaged in a bioerodible delivery technology (Durasert E™) for sustained delivery, in patients with wet age-related macular degeneration (wAMD) previously treated with anti-VEGF therapy. Design Phase I, multicenter, prospective, open-label, dose-escalation trial. Participants Patients with wAMD and evidence of prior anti-VEGF therapy response. Methods Patients received a single intravitreal injection of EYP-1901. Main Outcome Measures The primary objective was to evaluate safety and tolerability of EYP-1901. Secondary objectives assessed biologic activity of EYP-1901 including best-corrected visual acuity (BCVA) and central subfield thickness (CST). Exploratory analyses included reduction in anti-VEGF treatment burden and supplemental injection-free rates. Results Seventeen patients enrolled in the 440 μg (3 patients), 1030 μg (1 patient), 2060 μg (8 patients), and 3090 μg (5 patients) dose cohorts. No dose-limiting toxicity, ocular serious adverse events (AEs), or systemic AEs related to EYP-1901 were observed. There was no evidence of ocular or systemic toxicity related to vorolanib or the delivery technology. Moderate ocular treatment-emergent AEs (TEAEs) included reduced visual acuity (2/17) and retinal exudates (3/17). One patient with reduced BCVA had 3 separate reductions of 17, 18, and 16 letters, and another had a single drop of 25 letters. One severe TEAE, neovascular AMD (i.e., worsening/progressive disease activity), was reported in 1 of 17 study eyes but deemed unrelated to treatment. Mean change from baseline in BCVA was -1.8 letters and -5.4 letters at 6 and 12 months. Mean change from baseline in CST was +1.7 μm and +2.4 μm at 6 and 12 months. Reduction in treatment burden was 74% and 71% at 6 and 12 months. Of 16 study eyes, 13, 8, and 5 were injection-free up to 3, 6, and 12 months. Conclusion In the DAVIO trial (ClinicalTrials.gov identifier, NCT04747197), EYP-1901 had a favorable safety profile and was well tolerated in previously treated eyes with wAMD. Measures of biologic activity remained relatively stable following a single EYP-1901 injection. These preliminary data support ongoing phase II and planned phase III trials to assess efficacy and safety.

Intravitreal anti-vascular endothelial growth factor therapy for retinal diseases in Norway from 2011 to 2021: A combined registry and survey study. Acta Ophthalmol 2024; 102:544-554. [PMID: 38071435 DOI: 10.1111/aos.16598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 11/24/2023] [Accepted: 11/28/2023] [Indexed: 07/09/2024]
Abstract
PURPOSE To investigate the use of intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy in Norway from 2011 to 2021 and explore how the eye departments organized their injection services. METHODS We combined data from the Norwegian Patient Registry (NPR) with survey responses from Norway's 22 eye departments. The NPR data encompassed all registered intravitreal injection episodes from 2011 to 2021. The survey contained questions about local treatment practices and emphasized neovascular age-related macular degeneration (nAMD), retinal vein occlusion and diabetic macular edema. RESULTS A total of 47247 unique patients received 841 646 intravitreal injections in the study period. The number of patients per year increased from 6522 in 2011 to 20 635 in 2021. The number of injections per year increased from 30 926 in 2011 to 125 258 in 2021. The most frequent diagnosis was nAMD. In 2021, the age-adjusted treatment activity in Norway's 11 counties ranged from 47.8 to 75.5 injections per 1000 inhabitants aged ≥50 years. The use of aflibercept gradually exceeded bevacizumab, but the aflibercept proportion per county ranged from 38 to 82% in 2021. The survey revealed varying treatment practices, local guidelines were often absent, and only half of the departments defined a lower visual limit for initiating or maintaining treatment. CONCLUSION The use of intravitreal anti-VEGF therapy increased considerably from 2011 to 2021, but there was considerable regional variation in treatment activity, drug utilization and organization of injection services. These findings emphasize the need for strengthened governance and national guidelines to ensure equal treatment nationally.

Abstract
Purpose Limited data is available on treatment satisfaction with the management of wet age-related macular degeneration (wAMD) among patients in Italy. In this cross-sectional real-world study, treatment satisfaction with anti-vascular endothelial growth factor (anti-VEGFs) was assessed in patients with wAMD in Italy. Patients and Methods This was a non-interventional, cross-sectional survey involving patients with wAMD receiving anti-VEGFs. The survey was administered through a virtual assistant via phone. Patients' treatment satisfaction was assessed using a newly developed Novartis Tailored Treatment Satisfaction Questionnaire (NVS TTSQ) and the validated Macular Disease Treatment Satisfaction Questionnaire (MacTSQ). Results Overall, 154 evaluable patients were enrolled in 5 centers across Italy. The mean (SD) age of the patients was 76.8 years (7.01). Overall treatment satisfaction score assessed by NVS TTSQ was 40.50 (7.11), with a mean of 9.97 (1.84) on the information domain and 22.98 (4.57) on the unmet need domain. Patients were satisfied with diagnosis communication (4.99 [1.30]), information provided on treatment administration (4.58 [1.49], range 0-6), the waiting room (4.40 [1.43]), and management of visits and injections at the center (5.14 [1.12]), general management of maculopathy at the center (5.22 [1.01]). Patients were not satisfied with their independence in terms of disease management (2.56 [2.45]); they would like additional information about the disease (5.38 [1.03]) and to discuss the injection procedures (4.02 [1.94]) with already-treated patients. The overall treatment satisfaction score on MacTSQ scale was 55.84 (10.13). Conclusion Patients with wAMD are satisfied with the overall management of their disease in Italy. However, patients would like to have more information on prognosis and management of the disease.

Abstract
Treatment decisions for neovascular age-related macular degeneration (nAMD) in the setting of individualised treatment regimens are adapted to disease activity. The main marker of disease activity and trigger for re-treatment with anti-vascular endothelial growth factor (anti-VEGF) agents is the presence of retinal fluid on optical coherence tomography (OCT). Recently, attention has focused on the impact of residual retinal fluid on nAMD management. Based on a literature review and the combined clinical experience of an international group of retinal specialists, this manuscript provides expert guidance on the treatment of nAMD according to fluid status and proposes an algorithm for determining when to administer anti-VEGF treatment according to residual fluid status. We explore the role of residual fluid in treatment decisions and outcomes in nAMD, taking into consideration fluid evaluation and, in particular, distinguishing between fluid in different anatomic compartments and at different stages during the treatment course. Current limitations to identifying and interpreting fluid on OCT, and the assumption that any residual retinal fluid reflects ongoing VEGF activity, are discussed.

Stereotactic radiotherapy for neovascular age-related macular degeneration (STAR): a pivotal, randomised, double-masked, sham-controlled device trial. Lancet 2024; 404:44-54. [PMID: 38876132 DOI: 10.1016/s0140-6736(24)00687-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 03/19/2024] [Accepted: 04/03/2024] [Indexed: 06/16/2024]
Abstract
BACKGROUND Neovascular age-related macular degeneration (nAMD) is a leading cause of blindness. The first-line therapy is anti-vascular endothelial growth factor (anti-VEGF) agents delivered by intravitreal injection. Ionising radiation mitigates key pathogenic processes underlying nAMD, and therefore has therapeutic potential. STAR aimed to assess whether stereotactic radiotherapy (SRT) reduces the number of anti-VEGF injections required, without sacrificing visual acuity. METHODS This pivotal, randomised, double-masked, sham-controlled trial enrolled participants with pretreated chronic active nAMD from 30 UK hospitals. Participants were randomly allocated in a 2:1 ratio to 16-Gray (Gy) SRT delivered using a robotically controlled device or sham SRT, stratified by treatment centre. Eligible participants were aged 50 years or older and had chronic active nAMD, with at least three previous anti-VEGF injections, including at least one in the last 4 months. Participants and all trial and image reading centre staff were masked to treatment allocation, except one unmasked statistician. The primary outcome was the number of intravitreal ranibizumab injections required over 2 years, tested for superiority (fewer injections). The main secondary outcome was Early Treatment Diabetic Retinopathy Study visual acuity at two years, tested for non-inferiority (five-letter margin). The primary analysis used the intention-to-treat principle, and safety was analysed per-protocol on participants with available data. The study is registered with ClinicalTrials.gov (NCT02243878) and is closed for recruitment. FINDINGS 411 participants enrolled between Jan 1, 2015, and Dec 27, 2019, and 274 were randomly allocated to the 16-Gy SRT group and 137 to the sham SRT group. 240 (58%) of all participants were female, and 171 (42%) of all participants were male. 241 participants in the 16-Gy SRT group and 118 participants in the sham group were included in the final analysis, and 409 patients were treated and formed the safety population, of whom two patients allocated to sham treatment erroneously received 16-Gy SRT. The SRT group received a mean of 10·7 injections (SD 6·3) over 2 years versus 13·3 injections (5·8) with sham, a reduction of 2·9 injections after adjusting for treatment centre (95% CI -4·2 to -1·6, p<0·0001). The SRT group best-corrected visual acuity change was non-inferior to sham (adjusted mean letter loss difference between groups, -1·7 letters [95% CI -4·2 to 0·8]). Adverse event rates were similar across groups, but reading centre-detected microvascular abnormalities occurred in 77 SRT-treated eyes (35%) and 13 (12%) sham-treated eyes. Overall, eyes with microvascular abnormalities tended to have better best-corrected visual acuity than those without. Fewer ranibizumab injections offset the cost of SRT, saving a mean of £565 per participant (95% CI -332 to 1483). INTERPRETATION SRT can reduce ranibizumab treatment burden without compromising vision.

[PMID: 38965319 DOI: 10.1038/s41433-024-03218-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 05/27/2024] [Accepted: 06/26/2024] [Indexed: 07/06/2024] Open
Abstract
BACKGROUND Age-related macular degeneration (AMD) remains a primary cause of blindness, with neovascular AMD (nAMD) presenting particular treatment challenges. Despite anti-vascular endothelial growth factor (anti-VEGF) therapies, many patients exhibit a suboptimal response to the previously available anti-vascular endothelial growth factor (anti-VEGF) therapies. This study evaluates the efficacy and treatment interval extension of faricimab in this patient cohort. METHODS In a retrospective single-centre study at University Hospitals of Bristol and Weston, UK, nAMD patients suboptimally responsive to previous anti-VEGF therapies were switched to faricimab. Treatment started with an initiation phase of 4 monthly injections followed by a 'Treat and Extend' protocol. Outcomes included best-recorded visual acuity (BRVA), central subfield thickness (CST), the presence of retinal fluid, and treatment intervals. RESULTS Among 98 eyes of 79 patients, following faricimab treatment, significant reductions in CST and retinal fluid were noted, indicating decreased disease activity. While BRVA changes were not statistically significant, the anatomical improvements suggest a potential therapeutic benefit. Notably, 40% of patients achieved extended treatment intervals, reducing the treatment burden. CONCLUSION Faricimab offers a promising alternative for nAMD patients with suboptimal responses to prior anti-VEGF treatments, demonstrating significant anatomical improvements and the possibility of extended dosing intervals. These findings highlight the need for prospective real-world studies to further assess faricimab's role in nAMD management and its long-term impact on patient outcomes.

Abstract
The development of intravitreally injected biologic medicines (biologics) acting against vascular endothelial growth factor (VEGF) substantially improved the clinical outcomes of patients with common VEGF-driven retinal diseases. The relatively high cost of branded agents, however, represents a financial burden for most healthcare systems and patients, likely resulting in impaired access to treatment and poorer clinical outcomes for some patients. Biosimilar medicines (biosimilars) are clinically equivalent, potentially economic alternatives to reference products. Biosimilars approved by leading health authorities have been demonstrated to be similar to the reference product in a comprehensive comparability exercise, generating the totality of evidence necessary to support analytical, pre-clinical, and clinical biosimilarity. Anti-VEGF biosimilars have been entering the field of ophthalmology in the US since 2022. We review regulatory and scientific concepts of biosimilars, the biosimilar development landscape in ophthalmology, with a specific focus on anti-VEGF biosimilars, and discuss opportunities and challenges facing the uptake of biosimilars.

Abstract
Background/Objectives: This study aimed to assess the effectiveness of bi-monthly brolucimumab treatment in patients with neovascular age-related macular degeneration (nAMD) refractory to monthly aflibercept treatment. Methods: A retrospective chart review included 32 eyes of patients with refractory nAMD who switched from monthly intravitreal aflibercept treatment to bi-monthly intravitreal brolucizumab treatment. This study evaluated changes in visual acuity (VA), intraretinal fluid (IRF), subretinal fluid (SRF), pigment epithelial detachment (PED), and central macular thickness (CMT), at specific times as follows: baseline before switching (T0), 2 months after switching (T1), 4 months after switching (T2), and 6 months after switching (T3). Results: The mean best-corrected visual acuity (BCVA) did not significantly change across all time points (0.52 ± 0.12, 0.48 ± 0.27, 0.48 ± 0.28, and 0.50 ± 0.27 logarithms of the minimum angle of resolution in T0, T1, T2, and T3, respectively). CMT significantly decreased after additional brolucizumab injections compared to the baseline (218.2 ± 48.6 and 207.9 ± 49.8 μm, respectively; p = 0.001). The PED height also significantly decreased from 251.0 ± 165.4 to 154.4 ± 115.65 μm (p < 0.001), with complete resolution in nine patients (28%). The mean subfoveal choroidal thickness (SFCT) before brolucizumab treatment was 262.8 ± 79.7 μm, which decreased to 233.0 ± 71.2 μm (p = 0.001) after the first injection. The final SFCT also significantly decreased after additional brolucizumab injections compared to the baseline SFCT (p = 0.012). Conclusions: Bi-monthly brolucizumab treatment proves effective for patients refractory to monthly fixed aflibercept, resulting in positive anatomical changes without significant deterioration in visual acuity. This approach provides a promising prognosis while reducing the treatment burden on refractory patients.

Abstract
PURPOSE Pathological angiogenesis and vascular instability are observed in diabetic retinopathy (DR), diabetic macular edema (DME), and wet age-related macular degeneration (wAMD). Many receptor tyrosine kinases (RTKs) including vascular endothelial growth factor receptors (VEGFRs) contribute to angiogenesis, whereas the RTK TIE2 is important for vascular stability. Pan-VEGFR tyrosine kinase inhibitors (TKIs) such as vorolanib, sunitinib, and axitinib are of therapeutic interest over current antibody treatments that target only one or two ligands. This study compared the anti-angiogenic potential of these TKIs. METHODS A kinase HotSpot™ assay was conducted to identify TKIs inhibiting RTKs associated with angiogenesis and vascular stability. Half-maximal inhibitory concentration (IC50) for VEGFRs and TIE2 was determined for each TKI. In vitro angiogenesis inhibition was investigated using a human umbilical vein endothelial cell sprouting assay, and in vivo angiogenesis was studied using the chorioallantoic membrane assay. Melanin binding was assessed using a melanin-binding assay. Computer modeling was conducted to understand the TIE2-axitinib complex as well as interactions between vorolanib and VEGFRs. RESULTS Vorolanib, sunitinib, and axitinib inhibited RTKs of interest in angiogenesis and exhibited pan-VEGFR inhibition. HotSpot™ assay and TIE2 IC50 values showed that only axitinib potently inhibited TIE2 (up to 89%). All three TKIs effectively inhibited angiogenesis in vitro. In vivo, TKIs were more effective at inhibiting VEGF-induced angiogenesis than the anti-VEGF antibody bevacizumab. Of the three TKIs, only sunitinib bound melanin. TKIs differ in their classification and binding to VEGFRs, which is important because type II inhibitors have greater selectivity than type I TKIs. CONCLUSIONS Vorolanib, sunitinib, and axitinib exhibited pan-VEGFR inhibition and inhibited RTKs associated with pathological angiogenesis. Of the three TKIs, only axitinib potently inhibited TIE2 which is an undesired trait as TIE2 is essential for vascular stability. The findings support the use of vorolanib for therapeutic inhibition of angiogenesis observed in DR, DME, and wAMD.

Abstract
PURPOSE To identify baseline factors associated with 1-year outcomes when treating neovascular age-related macular degeneration (nAMD) with ranibizumab biosimilar SB11 or reference ranibizumab (rRBZ), and to compare efficacy of the two products within subgroups judged to be clinically relevant. DESIGN Post hoc analysis of a prospective, equivalence phase 3 randomized clinical trial (RCT) METHODS: 705 patients with nAMD were randomized 1:1 to receive SB11 or rRBZ for 48 weeks. Pooled and randomized groups were used to identify baseline factors associated with clinical outcomes at Week 52 using multiple linear regression models. Significant factors identified in regression analyses were confirmed in analyses of variance. Subgroup analyses comparing best-corrected visual acuity (BCVA) changes between SB11 and rRBZ were conducted. RESULTS 634 (89.9%) participants completed the 52-week visit. Regression analyses showed that younger age, lower BCVA, and smaller total lesion area at baseline were associated with greater BCVA gain at Week 52, while older age, lower BCVA, and thicker central subfield thickness (CST) at baseline were predictors of greater CST reduction in the pooled group. Subgroup analyses demonstrated that BCVA outcomes appeared comparable for the SB11 and rRBZ groups. CONCLUSION Post hoc analyses of the SB11-rRBZ equivalence study showed that baseline age, BCVA, CST, and total lesion area were prognostic factors for visual or anatomical outcomes of nAMD, while subgroup analyses demonstrated comparable results for SB11 and rRBZ. Collectively, the results appear comparable to similar RCTs of anti-vascular endothelial growth factor reference products for nAMD and strengthen confidence in the biosimilarity of SB11.

Graefes Arch Clin Exp Ophthalmol 2024; 262:1519-1530. [PMID: 38059999 DOI: 10.1007/s00417-023-06321-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 10/06/2023] [Accepted: 11/17/2023] [Indexed: 12/08/2023] Open
Abstract
PURPOSE Dysfunctions of retinal pigment epithelium (RPE) attributed to oxidative stress and inflammation are implicated with age-related macular degeneration (AMD). A debate on the curative role of metformin in AMD has been raised, though several recent clinical studies support the lower odds by using metformin. This study aimed to determine whether metformin could exert cytoprotection against RPE oxidative damages and the potential mechanisms. METHODS A cellular AMD model was established by treating ARPE-19 cells with hydrogen peroxide (H2O2) for 24 h. The reactive oxygen species (ROS) generation, expression of antioxidant enzymes, and levels of pro-inflammatory cytokines were monitored under administrations with H2O2 with/without metformin. The expression and DNA-binding activity of transcription factor erythroid-related factor 2 (Nrf2) were determined by western blot, immunofluorescence, and electrophoretic mobility shift assay. Knockout of Nrf2 was conducted by CRISPR/Cas9 gene deletion system. RESULTS Metformin pretreatment significantly improved the H2O2-induced low viability of ARPE-19 cells, reduced ROS production, and increased contents of antioxidative molecules. Concurrently, metformin also suppressed levels of pro-inflammatory cytokines caused by H2O2. The metformin-augmented nuclear translocation and DNA-binding activity of Nrf2 were further verified by the increased expression of its downstream targets. Genetic deletion of Nrf2 blocked the cytoprotective role of metformin. CONCLUSION Metformin possesses antioxidative and anti-inflammatory properties in ARPE-19 cells by activating the Nrf2 signaling. It supports the potential use for the control and prevention of AMD.

Abstract
INTRODUCTION In neovascular age-related macular degeneration (nAMD) trials, anti-VEGF injection frequency decreases after the first year, while outcomes remain primarily related to the number of injections. To the best of our knowledge, there are no reports of maintaining the best corrected visual acuity (BCVA) for more than 7 years in extension studies. OBJECTIVE To report a 12-year follow-up of a real-world case of nAMD where BCVA was preserved from declining. CASE DESCRIPTION A 67-year-old Caucasian female presented to our department in June 2010 due to decreased vision in her left eye (LE) within the preceding months. Examination showed a BCVA of 85 letters (L) in the right eye (RE) and 35 L in the LE. Fundus examination showed drusen in the macula of both eyes. Macular edema, loss of the macular lutein pigment, macular hypo/hyperpigmentation were observed in the LE. A diagnosis of Type 2 choroidal neovascular membrane (CNV) in the LE was established and within two months a Type 1 CNV developed in the RE. She undergone 9 injections of bevacizumab (six) and ranibizumab (three) within the first year of treatment in the LE and seven injections of ranibizumab within the first year in the RE. RESULTS The LE had a mean of 5.2 injections per year, and the RE had a mean of 7.5 injections per year, from 2010 to 2022. RE's BCVA dropped by 8L (85L to 77L) and central retinal thickness (CRT) increased by 16 μm (276 μm to 292 μm) while LE's BCVA increased by 28L (35L to 63L) and CRT decreased by 369 μm (680 μm to 311 μm), at the twelfth year. CONCLUSIONS Although the final visual outcome depends on baseline BCVA and lesion type or size, the number of injections is paramount in preserving BCVA and achieving favorable functional outcomes in nAMD, even after 12 years of treatment.

OPHTHALMOLOGY SCIENCE 2024; 4:100421.

Abstract
Purpose To evaluate anti-VEGF treatment patterns and the influence of patient demographic and clinical characteristics on up to 6-year vision outcomes in neovascular age-related macular degeneration. Design Retrospective, multicenter, noninterventional registry study with up to 6 years of follow-up. Participants A cohort of 254 655 eyes (226 767 patients) with first anti-VEGF injection and at least 2 years of follow-up; 160 423 eyes had visual acuity (VA) data. Methods Anonymized patient data were collected in the United States through the IRIS® Registry (Intelligent Research in Sight). Main Outcome Measures Changes in VA from baseline; frequency of and gaps between intravitreal anti-VEGF injections; treatment discontinuations; switching anti-VEGF agents; and influence of baseline clinical and demographic characteristics on VA. Results After a mean VA increase of 3.0 ETDRS letters at year 1, annual decreases led to a net loss from baseline of 4.6 letters after 6 years. Patients with longer follow-ups had better baseline and follow-up VA. From a mean of 7.2 in year 1 and 5.6 in year 2, mean injections plateaued between 4.2 to 4.6 in years 3 through 6. Treatment was discontinued in 38.8% of eyes and switched in 32.3%. When adjusting for differences at baseline, every additional injection resulted in a 0.68 letter improvement from baseline to year 1; thus, multiple injections in a year have the potential to be clinically meaningful. Older age, male gender, Medicaid insurance, and not being treated by a retina specialist were associated with a higher likelihood of vision loss at year 1. Of the patients, 58.5% lost ≥ 10 letters VA at least once during follow-up, with 14.5% of patients experiencing sustained poor vision after a median of 3.4 years. Conclusions After modest mean VA improvement with intravitreal anti-VEGF injections at year 1, patients netted a loss of VA by year 6. Injection frequency decreased over time, and this was paired with a relatively high rate of discontinuation. Modeling suggested that more frequent injections were associated with better VA. Difficulty with continuous adherence to frequent intravitreal injections may have contributed to undertreatment resulting in less-than-optimal vision outcomes.

Abstract
INTRODUCTION Remote monitoring of vision, using tools such as the shape discrimination hyperacuity (SDH) test, can detect disease activity in patients with maculopathy. We determined the in-clinic accuracy and repeatability of three myVisionTrack expanded version (mVTx) tests for self-testing of visual acuity (VA) and contrast sensitivity. METHODS Aphelion, a single-arm, prospective study conducted at two sites in the USA, included adults with any maculopathy and a baseline VA of 0.7 log of minimum angle of resolution (logMAR) (Snellen 20/100) or better. Participants completed the mVTx tests (tumbling E, Landolt C, contrast sensitivity, and SDH) and standard clinical tests (near and distance Early Treatment Diabetic Retinopathy Study [ETDRS] charts and the Pelli-Robson contrast sensitivity chart). Test-retest repeatability and agreement between the mVTx tests and the corresponding clinical test were assessed by Bland-Altman analyses. Participants also completed a usability survey. RESULTS The mean age of the 122 participants was 67 years. The most common diagnosis was age-related macular degeneration (42% of patients). The tumbling E test had a test-retest 95% limit of agreement (LoA) of ± 0.18 logMAR; the Landolt C test, ± 0.23 logMAR; the SDH test, ± 0.24 logMAR; and the contrast sensitivity test, ± 0.32 log contrast threshold (logCT). Compared with the distance ETDRS chart, the LoA was ± 0.35 logMAR for the tumbling E test (mean difference, - 0.07 logMAR) and ± 0.39 logMAR for the Landolt C test (mean difference, 0.03 logMAR). For the contrast sensitivity test, the LoA compared with the Pelli-Robson chart was ± 0.30 logCT (mean difference, - 0.25 logCT). Most participants (85%) reported that they learned the tests quickly. The tumbling E test scored the highest on ease of use. CONCLUSION The mVTx tests of VA are accurate and repeatable, supporting their potential use alongside the SDH test to detect disease progression remotely between clinic visits.

Abstract
BACKGROUND Unresolved retinal fluid and high injection burden are major challenges for patients with neovascular age-related macular degeneration. Brolucizumab addresses these challenges by providing robust vision gains and superior fluid resolution, with the potential for longer treatment intervals. Brolucizumab has been associated with adverse events of retinal vasculitis and retinal vascular occlusion typically in the presence of intraocular inflammation (IOI). To define the incidence of the adverse events, Novartis convened an external safety review committee, which found a rate of 4.6% for definite or probable IOI, 3.3% for retinal vasculitis, and 2.1% for retinal vascular occlusion in the HAWK and HARRIER trials. Novartis also established a coalition to explore 4 areas regarding the adverse events: root cause, patient characterization, event mitigation and vigilance, and treatment protocols for the adverse events. Based on the coalition findings, a risk mitigation framework was developed. Prior to initiating treatment with brolucizumab, it is important to weigh the potential benefit against risk of adverse events and to consider patient risk factors such as prior history of IOI and/or retinal vascular occlusion. To mitigate the potential for IOI-related adverse events, it is important to conduct a thorough dilated eye examination before each injection and closely monitor patients throughout treatment. Patients should be educated on symptoms of IOI to monitor for. Brolucizumab should not be injected in the presence of active IOI. If an adverse event is identified, prompt and intensive treatment should be considered. CONCLUSION Progress has been made in understanding how to mitigate IOI-related adverse events following treatment with brolucizumab.

Abstract
With a growing aging population, the prevalence of age-related eye disease and associated eye care is expected to increase. The anticipated growth in demand, coupled with recent medical advances that have transformed eye care for people living with retinal diseases, particularly neovascular age-related macular degeneration (nAMD) and diabetic eye disease, has presented an opportunity for health systems to proactively manage the expected burden of these diseases. To do so, we must take collective action to address existing and anticipated capacity limitations by designing and implementing sustainable strategies that enable health systems to provide an optimal standard of care. Sufficient capacity will enable us to streamline and personalize the patient experience, reduce treatment burden, enable more equitable access to care and ensure optimal health outcomes. Through a multi-modal approach that gathered unbiased perspectives from clinical experts and patient advocates from eight high-income countries, substantiated perspectives with evidence from the published literature and validated findings with the broader eye care community, we have exposed capacity challenges that are motivating the community to take action and advocate for change. Herein, we propose a collective call-to-action for the future management of retinal diseases and potential strategies to achieve better health outcomes for individuals at-risk of, or living with, retinal disease.

Abstract
Neovascular age-related macular degeneration (nAMD) leads to irreversible central vision loss if untreated. Frequent administration of anti-vascular endothelial growth factor (anti-VEGF) injections inhibits disease activity with excellent functional and morphological benefits. However, these injections pose a heavy therapeutic burden, and treatment discontinuation is common. Although current anti-VEGF treatment paradigms, such as treat-and-extend, mitigate treatment burden while still leading to acceptable vision outcomes, they fail to sustain initial vision gains for many. Novel longer-acting anti-VEGF therapies may reduce the overall burden on nAMD patients. Gene therapy might offer a paradigm shift by providing continuous expression of anti-VEGF, potentially decreasing treatment requirements and improving long-term vision outcomes.

Abstract
Purpose To explore outcomes and biomarkers associated with retinal fluid instability represented by a new parameter in neovascular age-related macular degeneration (nAMD). Methods Patients with treatment-naïve nAMD receiving anti-vascular endothelial growth factor (VEGF) injections for a duration of 1 to 3 years were consecutively reviewed. Fluctuation Index (FI) of each eye, calculated by averaging the sum of differences in 1-mm central subfield thickness between each follow-up from months 3 to 24, was arranged into ascending order from the lowest to the highest and split equally into low, moderate, and high fluctuation groups. Outcomes were analyzed at 24 months. Results Of 558 eyes, FI values showed a negative correlation with a degree-response gradient with 24-month visual improvement. After controlling for baseline best-corrected visual acuity and potential confounders, eyes with low fluctuation gained more Early Treatment Diabetic Retinopathy Study letters than those in the moderate and high fluctuation group (Δ, 10.1 and 14.0 letters, respectively). Significant best-corrected visual acuity improvement from baseline to month 24 (11.8 letters) was observed exclusively in the low fluctuation group despite the indifference in the number of injections and types of anti-VEGF drug used among groups. Patients presenting with central subfield thickness of ≥405 µm or intraretinal fluid coinciding with subretinal fluid showed a significant association with foveal thickness instability during the maintenance phase. Conclusions Apart from the central subfield thickness values, unstable macular thickening represented by the FI was associated with some baseline features and may contribute to substandard visual outcomes. Translational Relevance FI may be a valuable tool for assessing therapeutic adequacy in the treatment of nAMD.

Abstract
INTRODUCTION Timely anti-vascular endothelial growth factor (VEGF) treatment is crucial for visual function in neovascular age-related macular degeneration (nAMD). The aim of this study was to assess the reasons for anti-VEGF treatment delay during the COVID-19 lockdown and its clinical impact in patients with nAMD. METHODS A retrospective, observational, multicentre study in patients with nAMD treated with anti-VEGF therapy was performed in 16 centres nationwide. Data were retrieved from the FRB Spain registry, patient medical records and administrative databases. Patients were divided into two groups based on whether they received or missed intravitreal injections during the COVID-19 lockdown. RESULTS A total of 302 eyes from 245 patients were included (timely treated group [TTG] 126 eyes; delayed treatment group [DTG] 176 eyes). Visual acuity (VA; ETDRS letters) decreased from baseline to post-lockdown visit in the DTG (mean [standard deviation] 59.1 (20.8) vs. 57.1 (19.7); p = 0.020) and was maintained in the TTG (64.2 [16.5] vs. 63.6 [17.5]; p = 0.806). VA worsened by an average of - 2.0 letters in the DTG and by - 0.6 in the TTG (p = 0.016). A higher proportion of visits were cancelled due to hospital overload in the TTG (76.5%) than in the DTG (47%), and a higher proportion of patients missed visits in the DTG (53%) than in the TTG (23.5%, p = 0.021), with fear of COVID-19 infection being the main reason for missed visits (60%/50%). CONCLUSIONS Treatment delays were caused by both hospital saturation and patients' decision; the latter being mainly driven by fear of COVID-19 infection. These delays had a detrimental effect on the visual outcomes in nAMD patients.

Randomized Trial of Biosimilar XSB-001 versus Reference Ranibizumab in Patients with Neovascular Age-Related Macular Degeneration. Ophthalmol Retina 2023; 7:753-761. [PMID: 37179017 DOI: 10.1016/j.oret.2023.05.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 05/04/2023] [Accepted: 05/05/2023] [Indexed: 05/15/2023]
Abstract
OBJECTIVE To evaluate the efficacy, safety, and immunogenicity of a ranibizumab biosimilar candidate (XSB-001) versus reference product (Lucentis) for neovascular age-related macular degeneration (nAMD). DESIGN Phase III, multicenter, randomized, double-masked, parallel-group study. PARTICIPANTS Patients with nAMD. METHODS Eligible patients were randomized (1:1) to receive intravitreal injections of XSB-001 or reference ranibizumab (0.5 mg [0.05 ml]) in the study eye once every 4 weeks for 52 weeks. Efficacy and safety assessments continued through 52 weeks of treatment. MAIN OUTCOME MEASURES Primary end point was change from baseline in best-corrected visual acuity (BCVA) by ETDRS letters at week 8. Biosimilarity was concluded if the 2-sided 90% confidence interval (CI) (United States) or 95% CI (rest of world) for the difference in least-squares (LS) mean change in BCVA at week 8 between treatment groups was within the predefined equivalence margin of ± 3.5 letters. RESULTS In total, 582 patients (n = 292 XSB-001, n = 290 reference ranibizumab) were randomized. Mean age was 74.1 years, most patients (85.2%) were White, and 55.8% were women. Mean BCVA score at baseline was 61.7 and 61.5 ETDRS letters in the XSB-001 and reference ranibizumab groups, respectively. At week 8, the LS mean (standard error [SE]) change in BCVA from baseline was 4.6 (0.5) ETDRS letters in the XSB-001 group and 6.4 (0.5) letters in the reference ranibizumab group (LS mean [SE] treatment difference: -1.8 [0.7] ETDRS letters; 90% CI, -2.9 to -0.7; 95% CI, -3.1 to -0.5). The 90% CI and 95% CI for LS mean difference in change from baseline were within the predefined equivalence margin. At week 52, LS mean (SE) change in BCVA was 6.4 (0.8) and 7.8 (0.8) letters, respectively (LS mean [SE] treatment difference, -1.5 [1.1] ETDRS letters; 90% CI, -3.3 to 0.4; 95% CI, -3.6 to 0.7). There were no clinically meaningful differences between treatments in anatomical, safety, or immunogenicity end points through week 52. CONCLUSIONS XSB-001 demonstrated biosimilarity to reference ranibizumab in patients with nAMD. Treatment with XSB-001 for 52 weeks was generally safe and well tolerated, with a safety profile similar to the reference product.

Short-Term Treatment Outcomes of Brolucizumab in Patients with Neovascular Age-Related Macular Degeneration: A Multicentre Indian Real-World Evidence Study. Clin Ophthalmol 2023; 17:2295-2307. [PMID: 37583576 PMCID: PMC10424695 DOI: 10.2147/opth.s415044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Accepted: 07/25/2023] [Indexed: 08/17/2023] Open
Abstract
Objective To evaluate the short-term effectiveness and safety outcomes following brolucizumab treatment in patients with neovascular age-related macular degeneration (nAMD) as a part of real-world clinical practice in India. Methods This was a retrospective, observational, multicentre study including patients (≥50 years old) diagnosed with nAMD. Anonymized data of the patients receiving the first dose of brolucizumab intravitreal injection (IVI) who were either treatment-naïve or previously treated with a single or a combination of other anti-VEGF IVIs were included. The present study reported the change in retinal fluid levels from baseline to month 3, best-corrected visual acuity (BCVA), central retinal thickness (CRT), and the number of injections received. The adverse events in the three months after brolucizumab treatment initiation were also monitored. Results The study included 63 patients (65 eyes) from four study centres across India (mean age: 69.1 ± 9.7 years). A total of 82 brolucizumab injections were administered during the 3 months of study duration, with 52/65 (80.0%) eyes receiving only 1 injection. Resolution of IRF, SRF, and PED was observed in 76.9%, 64.6%, and 67.7% of eyes, respectively. Further, a significant reduction in CRT was observed (baseline: 403.5 ± 118.7 μm; month 3: 308.3 ± 73.8 μm; p < 0.001), and BCVA also improved notably from 0.7 ± 0.5 logMAR at baseline to 0.5 ± 0.4 logMAR at month 3 (p < 0.001). Adverse events (AEs) were reported in 3 eyes from 3 patients; retinal pigment epithelial rip (1) and subretinal hemorrhage (2) after the first injection of brolucizumab, however, none discontinued the treatment. Conclusion The study reports on the short-term effectiveness and tolerability of brolucizumab therapy in the management of nAMD in both treatment-naïve and switch eyes. Brolucizumab was observed to have a favourable benefit-risk profile, and study results were within the known safety profile, with no instances of intraocular inflammation.

Abstract
The way a drug molecule is administered has always had a profound impact on people requiring medical interventions - from vaccine development to cancer therapeutics. In the Controlled Release Society Fall Symposium 2022, a trans-institutional group of scientists from industry, academia, and non-governmental organizations discussed what a breakthrough in the field of drug delivery constitutes. On the basis of these discussions, we classified drug delivery breakthrough technologies into three categories. In category 1, drug delivery systems enable treatment for new molecular entities per se, for instance by overcoming biological barriers. In category 2, drug delivery systems optimize efficacy and/or safety of an existing drug, for instance by directing distribution to their target tissue, by replacing toxic excipients, or by changing the dosing reqimen. In category 3, drug delivery systems improve global access by fostering use in low-resource settings, for instance by facilitating drug administration outside of a controlled health care institutional setting. We recognize that certain breakthroughs can be classified in more than one category. It was concluded that in order to create a true breakthrough technology, multidisciplinary collaboration is mandated to move from pure technical inventions to true innovations addressing key current and emerging unmet health care needs.

Abstract
Neovascular age-related macular degeneration (nAMD) with choroidal neovascularization (CNV) is a leading cause of blindness in the elderly in developed countries. The disease is currently treated with anti-angiogenic biologics, including aflibercept, against vascular endothelial growth factor (VEGF) but with limited efficacy, treatment resistance and requirement for frequent intravitreal injections. Although anti-VEGF gene therapy may provide sustained therapy that obviates multiple injections, the efficacy and side effects related to VEGF pathway targeting remain, and alternative strategies to block angiogenesis independently of VEGF are needed. We recently reported that secretogranin III (Scg3) induces only pathological angiogenesis through VEGF-independent pathways, and Scg3-neutralizing antibodies selectively inhibit pathological but not physiological angiogenesis in mouse proliferative retinopathy models. Anti-Scg3 antibodies synergize dose-dependently with VEGF inhibitors in a CNV model. Here, we report that an adeno-associated virus-8 (AAV8) vector expressing anti-Scg3 Fab ameliorated CNV with an efficacy similar to that of AAV-aflibercept in a mouse model. This study is the first to test an anti-angiogenic gene therapy protocol that selectively targets pathological angiogenesis via a VEGF-independent mechanism. The findings support further safety/efficacy studies of anti-Scg3 gene therapy as monotherapy or combined with anti-VEGF to treat nAMD.

Impact of an immersive, interactive medical education initiative on guideline-based retinal disease management knowledge/competence and effectual practice change. BMC Ophthalmol 2023; 23:285. [PMID: 37349689 DOI: 10.1186/s12886-023-03034-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Accepted: 06/10/2023] [Indexed: 06/24/2023] Open
Abstract
BACKGROUND Retinal diseases, including wet or dry age-related macular degeneration, diabetic macular edema, and diabetic retinopathy (DR), are underdiagnosed and undertreated in the United States. Clinical trials support the effectiveness of anti-vascular endothelial growth factor (anti-VEGF) therapies for several retinal conditions, but real-world data suggest underuse by clinicians, resulting in patients experiencing poorer visual outcomes over time. Continuing education (CE) has demonstrated effectiveness at changing practice behaviors, but more research is needed to understand whether CE can help address diagnostic and treatment gaps. METHODS This test and control matched pair analysis examined pre-/post-test knowledge of retinal diseases and guideline-based screening and intervention among 10,786 healthcare practitioners (i.e., retina specialists, ophthalmologists, optometrists, primary care providers, diabetes educators, pharmacists/managed care specialists, and other healthcare providers, such as registered nurses, nurse practitioners, and physician assistants) who participated in a modular, interactive CE initiative. An additional medical claims analysis provided data on practice change, evaluating use of VEGF-A inhibitors among retina specialist and ophthalmologist learners (n = 7,827) pre-/post-education, compared to a matched control group of non-learners. Outcomes were pre-/post-test change in knowledge/competence and clinical change in application of anti-VEGF therapy, as identified by the medical claims analysis. RESULTS Learners significantly improved knowledge/competence scores on early identification and treatment, identifying patients who could benefit from anti-VEGF agents, using guideline-recommended care, recognizing the importance of screening and referral, and recognizing the importance of early detection and care for DR (all P-values = 0.003 to 0.004). Compared with matched controls, learners' incremental total injections for anti-VEGF agents for retinal conditions increased more after the CE intervention (P < 0.001); specifically, there were 18,513 more (new) anti-VEGF injections prescribed versus non-learners (P < 0.001). CONCLUSIONS This modular, interactive, immersive CE initiative resulted in significant knowledge/competence gains among retinal disease care providers and changes in practice-related treatment behaviors (i.e., appropriate consideration and greater incorporation of guideline-recommended anti-VEGF therapies) among participating ophthalmologists and retina specialists compared to matched controls. Future studies will utilize medical claims data to show longitudinal impact of this CE initiative on treatment behavior among specialists and impact on diagnosis and referral rates among optometrists and primary care providers who participate in future programming.

Abstract
PURPOSE To evaluate long-term visual and anatomical outcomes in neovascular age-related macular degeneration (nAMD) patients treated with anti-vascular endothelial growth factor (VEGF) agents depending on the time delay from confirmed diagnosis to treatment initiation. MATERIALS AND METHODS Seventy-three nAMD patients (73 eyes) treated with anti-VEGF agents for 12 months using the pro re nata regimen were included in this retrospective longitudinal study. Patients were split into 3 groups according to the time from diagnosis to first anti-VEGF injection: < 48 h (group 1); 48 h-7 days (group 2); > 7 days (group 3). Decimal best-corrected visual acuity (VA) and macular thickness (MT) were recorded at baseline and 1-2-, 3-4-, 6- and 12-month later. Furthermore, age, gender as well as the applied treatment and number of injections after 12 months of treatment were also registered and compared. RESULTS Long-term effect of the treatment demonstrated enhanced VA in group 1 patients compared with the rest of groups after 1-2-, 6-, and 12-month follow-up (P < 0.05). Positive effects of early treatment were additionally corroborated by the augmented percentage of patients with normal VA in the group 1 respect to the rest of groups over studied time points (P < 0.05). Moreover, the VA gain in nAMD at group 1 was obtained with a mean of 3.7 intravitreal injections over 1-year follow-up period. Regarding MT, non-significant difference was observed among groups. CONCLUSIONS An early initial treatment with VEGF inhibitors is critical to achieve the best functional benefits of this therapy in new-onset nAMD patients.

Longer treatment intervals are associated with reduced treatment persistence in neovascular age related macular degeneration. Eye (Lond) 2023; 37:467-473.

Abstract
AIMS To test the hypothesis that patients treated for neovascular age related macular degeneration (nAMD) with longer treatment intervals are more likely to persist with treatment. METHODS Data were obtained from the prospectively-defined Fight Retinal Blindness! registry. Treatment interval at 2 years was stratified based on the mean treatment interval over the three visits prior to and including the 2-year visit. Rates of non-persistence to follow-up were assessed from 2 to 5 years. RESULTS Data from 1538 eyes were included. The overall rate of non-persistence was 51% at 5 years. Patients on longer treatment intervals (12-weeks) at 2 years were found to be less persistent to long-term follow-up. These eyes were found to have fewer active disease visits in the first 2 years (40%) than eyes treated at 4-weekly intervals (66%, p < 0.001). In the multivariable analysis, better vision at 2 years was associated with a lower risk of non-persistence (hazards ratio [HR] [95% CI]: 0.95 [0.93, 0.97], P < 0.001), while longer treatment intervals (HR [95% CI]: 1.31 [0.95, 1.8] and 1.54 [1.15, 2.06] for 12-week and > 12-week intervals vs. 4-week intervals, respectively, P = 0.002) and older patients (HR [95% CI]: 1.03 [1.02, 1.04], p < 0.001) were at higher risk of non-persistence. CONCLUSIONS We found that patients on longer treatment intervals at 2 years were more likely to be non-persistent with treatment in later years. Reinforcing the need for ongoing treatment is important for patients on longer intervals who may feel complacent or that treatment is no longer effective, particularly if newer, longer lasting agents become widely available.

Abstract
PURPOSE To evaluate the changes in visual impairment (VI) due to age-related macular degeneration (AMD) during the past 40 years and the impact of novel therapies at population level. METHODS In this nationwide register-based study, we assessed the incidence, prevalence, severity, and onset age of VI due to AMD based on the Finnish Register of Visual Impairment data from 1980 to 2019. Our data included 30 016 visually impaired persons with AMD as the main diagnosis for VI. The number of persons treated with intravitreal injections in Finland was obtained from hospital data kept by the Finnish Institute for Health and Welfare. RESULTS Between the 1980s and the 2010s, the incidence of reported VI doubled; however, this increase has stagnated in the 2010s. Since 2012, the prevalence of reported VI has decreased. The number of patients treated with intravitreal injections showed a 40-fold increase during 2005-2019. The severity of reported VI has decreased whereas the mean age at the onset of reported VI has increased during the 40 years. The age-adjusted incidence and prevalence of reported VI were significantly higher in females in comparison to males in all decades. CONCLUSION Increase in the incidence and prevalence of VI due to AMD in the past decades has stagnated and shifted to older age in the 2010s when therapies for exudative class became commonly available. Furthermore, the prognosis of VI has improved during the past 40 years. These positive trends are likely contributable to improved diagnostic tools, earlier diagnoses, and new therapy options.

Abstract
Intravitreal injections of anti-vascular endothelial growth factor (VEGF) agents are used to treat wet age-related macular degeneration (wAMD); however, they are associated with a considerable treatment burden and poor real-world outcomes. The molecular size and charge of anti-VEGF agents influence drug pharmacokinetics in the vitreous and peak drug efficacy. This article reviews the established and novel strategies to prolong drug action, in the vitreal cavity, and thus reduce dosing frequency. Increased ocular residency can be attained by increasing drug size as with large molecules, such as KSI-301; adding polyethylene glycol to pegcetacoplan (APL-2) or avacincaptad pegol to increase molecular size; or binding to other targets that increase molecular size, such as vitreal albumin in the case of BI-X. Faricimab is a bispecific antibody in which the fragment crystallizable portion is engineered to prolong ocular residency and reduce systemic exposure. Conversely, small VEGF-binding molecules, such as brolucizumab, can be administered at higher clinical doses, with the potential for prolonged clinical activity versus larger molecules. Other important considerations include sustained drug delivery routes, such as the ranibizumab port delivery system or subconjunctival or suprachoroidal injection. More effective and longer-lasting treatments are needed for wAMD to prolong drug action and reduce dosing frequency. Several strategies are under investigation and the prevention of vision loss in patients with AMD or other retinal diseases may be attainable in the near future.

Abstract
Purpose: to study long-term results of anti-VEGF therapy for macular diseases of patients followed up for 60 months in real clinical practice. Materials and methods. The research group included 57 patients (43 women, 14 men; median age 62 years) who received antiVEGF therapy (ranibizumab, aflibercept) and remained under regular observation for 60 months. Of these, 24 patients had “wet” agerelated macular degeneration (wAMD), 20 had myopic choroidal neovascularization (mCNV), 10 had macular edema due to retinal vein occlusions (MERVO), and 3 patients had diabetic macular edema (DME). Statistical analysis of demographic indicators and treatment results was carried out using STATISTICA 13.3 software: conditions of normality for variables, nonparametric and parametric criteria were determined, and rank analysis of variance was carried out. The characteristics of the study group are given in the first part of this article [ROJ, 2022; 15 (3): 11–17]. Results. Over the research period, the best corrected visual acuity (BCVA) increased from 0.29 0.35 0.42 to 0.47 0.54 0.61 (p < 0.00001); 91.2 % of patients maintained the indicator or improved it with regard to the baseline. The proportion of subjects with BCVA ≥ 0.5 ranged from 61.4 to 73.7 % during the research period. The average number of intravitreal injections (IVI) received by the patients was 8.93 10.84 12.75. We revealed a tendency towards a gradual decrease in the intensity of treatment and confirmed it (p < 0.00001). The proportion of patients who received 4 IVI or more over 12 months of treatment decreased from 57.9 % in the first year to 12.3 % in the fifth year, and the proportion of cases where anti-VEGF therapy did not need to be resumed before the end of the year of treatment increased from 28.1 % (in the second year of research) to 49.1 % (in the fifth year). The need for IVI anti-VEGF drugs in wAMD and DME was significantly greater than in MERVO and mCNV. Conclusion. The results confirm high efficiency of anti-VEGF therapy. To solve the issue of ill-timed or insufficient treatment, it is necessary to start the therapy as early as possible, use the most effective (proactive) regimens, apply individualized approach to the treatment, take organizational measures aimed at facilitation of access to specialized care, and, generally, to change the attitude of the professional community.

Clin Ophthalmol 2022; 16:3959-3972. [PMCID: PMC9719699 DOI: 10.2147/opth.s391082] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Accepted: 11/02/2022] [Indexed: 12/05/2022] Open
Abstract
Purpose To analyze the use of artificial tears in patients undergoing treatment with anti-vascular endothelial growth (anti-VEGF) intravitreal injections. Methods Thirty-four eyes undergoing anti-VEGF treatment were analyzed. Each patient underwent a subjective and objective evaluation of the ocular surface, using the Ocular Surface Disease Index (OSDI), Dry Eye Questionnaire (DEQ)-5, tear meniscus height (TMH), first and average non-invasive Keratograph Break-Up Time (NIKBUT), bulbar conjunctival redness, meibography and the Vision Break-Up Time (VBUT). Patients attended 5 visits (days 0, 7, 30, 37, and 60). All patients continued with their intravitreal injection treatment during the study (days 0, 30, and 60). Patients did not receive any artificial tear treatment during the first month of the study, and at the baseline visit they were randomly assigned to one of two study groups to receive either the Systane Hydration or the Viscofresh 10mg/mL formulation. Patients were instructed to instill one drop of the assigned study treatment 3 times a day for 30 days during the second month of the study. Results According to the Mixed Models for Repeated Measures analysis, there is not enough statistical evidence for any of the parameters examined to determine significant differences between being treated with artificial tears and not being treated (p > 0.05). There is, however, a tendency toward improved outcomes in some parameters when artificial tears were used. OSDI, DEQ-5, TMH, and meibography were not affected by either the type of artificial tear used or by the time (from day 30 to day 60; p > 0.05), but the NIKBUT and VBUT values increased over time during this period regardless of which treatment the patient was receiving. Conclusion The use of artificial tears may help to keep the tear film stable Future studies with larger samples should be conducted to elucidate whether the tendency reported in our study becomes significant.

Abstract
AIMS To evaluate the long-term functional and anatomical outcomes of neovascular age-related macular degeneration (nvAMD) treated with intravitreal anti-vascular endothelial growth factor (anti-VEGF) for up to 10 years, and to identify associated risk factors. METHODS Clinical and optical coherence tomography findings were retrieved for nvAMD cases treated with intravitreal anti-VEGF compounds using a treat-and-extend protocol. In addition, the major risk alleles for AMD in the CFH (rs1061170), HTRA1 (rs1200638) and C3 (rs2230199) genes were genotyped. RESULTS From 276 eligible eyes in 206 patients, 80 eyes (29%) in 66 patients (32.0%) had a follow-up period of ≥8 years and were included in this study. Over a 10-year period, 73.3±28.0 (mean±SD) anti-VEGF injections were administered. Best-corrected visual acuity (BCVA; LogMAR) deteriorated from 0.55±0.53 at baseline to 1.00±0.73 at 10 years (p<0.0005). Central subfield thickness (CST) decreased from 415.8±162.1 µm at baseline to 323±113.6 µm (p<0.0005) after three monthly injections and remained lower than baseline throughout the follow-up period. Visual outcome was associated with BCVA and intraretinal fluid (IRF) at baseline, macular atrophy, and macular thinning at follow-up. The decrease in CST was inversely correlated with the number of CFH and/or C3 risk alleles carried by the patient (Pearson's r: -0.608; p=0.003). CONCLUSIONS Patients with nvAMD who received anti-VEGF therapy for 10 years developed substantial vision loss associated with the presence of IRF at baseline and macular atrophy. Major risk alleles for AMD in two complement genes were associated with a reduced long-term reduction in macular thickness.

Abstract
Age-related macular degeneration (AMD) represents a leading cause of blindness worldwide. Neovascular AMD (nAMD) is a subtype of AMD most frequently treated with intravitreal anti-vascular endothelial growth factor (aVEGF) injections, which has allowed for patients to maintain vision that would have otherwise been lost. However, the need for frequent intravitreal injections for optimal results poses a risk for undertreatment in nAMD patients due to the high treatment burden associated with current aVEGF therapy. Many novel agents and pathways are being explored and targeted for less burdensome treatment options, one of which is the ranibizumab port delivery system (PDS). The PDS is a surgically implanted, refillable device that allows for the sustained release of ranibizumab, a widely used aVEGF agent, into the vitreous cavity. Positive results non-inferior to monthly ranibizumab injections in both phase II and phase III clinical trials allowed for FDA approval of the device with refill intervals of 6 months, which represents the longest approved treatment interval to date for nAMD therapy. This article reviews the need for a durable nAMD treatment option in real-world practice, the clinical trial and extension study data for the PDS, the risk of adverse events and safety profile of the PDS and the potential clinical role of the PDS in answering the real-world needs of nAMD treatment. In addition, other pipeline sustained-treatment modalities are discussed in the context of ongoing clinical trials.

Abstract
To evaluate the real-world treatment outcomes in patients with neovascular age-related macular degeneration (nAMD) in Korea, focusing on retinal fluid resolution. This multi-institutional retrospective chart review study, analyzed medical records of patients with nAMD (age ≥ 50 years) who received their first anti-vascular endothelial growth factor (VEGF) treatment in ophthalmology clinics across South Korea between January 2017 and March 2019. The primary endpoint was the proportion of patients with retinal fluid after 12 months of anti-VEGF treatment. The association between fluid-free period and VA gains was also evaluated. A total of 600 patients were enrolled. At baseline, 97.16% of patients had retinal fluid; after 12 months of anti-VEGF treatment, 58.10% of patients had persistent retinal fluid. VA improvements were relatively better in patients with absence of retinal fluid compared with presence of retinal fluid (+ 12.29 letters vs. + 6.45 letters at month 12; P < .0001). Longer duration of absence of retinal fluid over first 12 months correlated with better VA gains at month 12 (P < .01). More than half of the study patients with nAMD had retinal fluid even after 12 months of treatment with their current anti-VEGF. Presence of retinal fluid was associated with relatively worse VA outcomes.

Abstract
Purpose
(1) To investigate the relative importance of convenience (consultation frequency and injection frequency) against treatment outcomes (visual and anatomical outcomes) and out-of-pocket medical costs via a discrete choice experiment (DCE), and (2) to investigate how patient characteristics affect patient treatment preferences.
Methods
Eligibility criteria were: (1) receiving a neovascular age-related macular degeneration (nAMD) diagnosis; (2) receiving anti-VEGF treatment; (3) being ≥21 years old, and (4) being able to speak and understand English/Mandarin. Patients were presented with eight choice tasks and asked to choose between their current treatment and two hypothetical treatments that varied by six attributes: number of clinic visits in a year, number of injections in a year, vision quality, control of swelling in retina, drug labelling and out-of-pocket cost.
Results
This analysis involved 180 patients. Based on latent class logistic regressions, vision quality was the most important attribute (34%) followed by cost (24%). The frequency of total clinic visits (15%) was the third most-important attribute, closely followed by labelling (12%) and control of retina swelling (11%). Injection frequency was the least important attribute (4%).
Conclusions
Vision quality was the most important attribute followed by the out-of-pocket costs. Given the same outcomes, patients preferred treatment regimens which require fewer total clinic visits. In comparison, injection frequency alone did not influence patient preferences. With increasing treatment options for nAMD, understanding patients’ preferences can help clinicians in selecting agents and treatment regimen most preferred for each patient, which may lead to improved long-term adherence and outcomes.

Abstract
PURPOSE Brolucizumab, a new generation anti-VEGF, has demonstrated efficacy and safety in AMD in the pivotal HAWK and HARRIER trials. Post-marketing, previously undetected adverse events related to intraocular inflammation have been reported. An independent post hoc review of the pivotal trials puts the rate of IOI at 4.6%. The aim of this paper is to propose a set of recommendations for implementing the management of brolucizumab in clinical practice. METHODS The recommendations made by the authors are based on their clinical experience, critical review of (i) the pivotal trials, the post-hoc analysis of the Safety Review Committee, (ii), and (iii) the published literature. RESULTS In the pivotal trials, brolucizumab showed sustained functional gains, superior anatomical outcomes with potentially longer intervals between injections and a well-tolerated overall safety profile. Adverse events reported post-marketing include retinal vasculitis and retinal vascular occlusion. Based on the available information, experts recommend (i) ruling out non-recommended patient profiles (prior history of ORI), (ii) screening the patient prior to each injection to rule out active ORI, (iii) monitoring the patient for early warning signs, and (iv) treating immediately should any adverse events develop. CONCLUSIONS The adverse events reported are rare, but may be associated with severe and irreversible loss of visual acuity. The recommendations made are intended to facilitate the management of brolucizumab in the routine practice of retinologists, to ensure patient safety and, should any adverse events occur, to minimise their impact on vision.

Abstract
PURPOSE To assess the association between treatment interval and likelihood of anti-vascular endothelial growth factor (anti-VEGF) discontinuation among patients with neovascular age-related macular degeneration (nAMD) in a real-world setting US. DESIGN Retrospective clinical cohort study. METHODS Health insurance claims data from the IBM MarketScan® Commercial and Medicare Supplemental databases were retrospectively reviewed to identify adults with nAMD who received anti-VEGF for the first time between 1 January 2011 and 30 June 2020. The proportion of discontinued patients was analyzed using Kaplan-Meier curves. Cox proportional hazards models were used to examine the association between treatment intervals at 24 months and anti-VEGF discontinuation. RESULTS The analysis included 8,167 patients on continuous, unilateral anti-VEGF treatment for at least 24 months. Baseline demographics and clinical characteristics were well balanced between treatment interval groups. The overall rate of discontinuation from 24 months until 60 months after treatment initiation was 30.4%. At 60 months, patients on shorter treatment intervals were more likely to remain on treatment than those on longer intervals, ranging from 76.8% (4-week interval group) to 60.6% (>12-week interval group) and corresponding to a 28% lower likelihood (HR [SE] 0.72 [0.12], p<0.01) and 55% higher likelihood of discontinuing treatment (HR [SE] 1.55 [0.07], p<0.01), respectively, compared with the 8-week group. CONCLUSIONS nAMD patients on longer anti-VEGF treatment intervals at 24 months had consistently higher discontinuation rates than patients on shorter intervals in the following years. This highlights the need to support and educate patients on long treatment intervals to continue with their treatment.

Abstract
PURPOSE To compare the 12 months visual and anatomical outcomes of treatment-naïve neovascular age-related macular degeneration (nAMD) patients diagnosed by optical coherence tomography angiography (OCT-A) compared with fluorescein angiography (FA)/indocyanine green angiography (ICGA), after anti-VEGF treatment in a real-world setting. METHODS Monocentric, observational, parallel-group study of nAMD patients diagnosed with either FA/ICGA or non-invasive OCT-A methods. Patients were treated with a fixed dosing regimen of intravitreal ranibizumab or aflibercept and followed up for 12 months. Primary outcomes were the 12 months functional (BCVA) and anatomical (CST reduction) gains between the two groups. The stratification of BCVA and CST gains by type of neovascular lesion and by anti-VEGF treatment was also assessed. RESULTS Seventy-two patients received FA/ICGA for the initial diagnosis of nAMD, while 73 received OCT-A. Overall, the mean BCVA gain at 12 months was 11.5 ± 9.6 letters. There were no statistically significant differences between the invasive and non-invasive imaging groups in BCVA gain (p = 0.87) or CST reduction (p = 0.76). No statistically significant outcome differences between different lesion types and the two drugs were observed. CONCLUSION In a real-world setting, nAMD patients diagnosed with OCT-A showed meaningful improvements in visual and anatomical parameters during 12 months of treatment, without significant differences with those diagnosed by invasive modalities.

Abstract
PURPOSE For the elderly in nursery homes, a visit to the ophthalmologist is a burden, which might lead to undertreatment. We have recently started offering a novel ophthalmological service combining onsite examination and telemedical interpretation for patients with limited access to ophthalmological care. This study summarises the frequency of findings of treatable eye diseases after the first year of operation in participants who dropped out from regular ophthalmological control. METHODS Participants' clinical characteristics, frequency of service utilisation, and findings were extracted from the system and analysed. RESULTS Of 1946 residents approached, 540 (27.7%; 1080 eyes) signed up for the service. A complete examination was possible in 412 persons (813 eyes) and partially possible in the remaining 128. The mean age of the examined participants mean age was 83.9 years (SD 9.7), and they were predominantly female (69.8%). The majority had a diagnosis of dementia (54.5%) and 20.2% had diabetes mellitus requiring treatment. The median care level (ranging from 0 - 12) was 7 (interquartile range 6 - 9), corresponding to a care need of 121 - 140 min/d. The mean best-corrected decimal visual acuity was 0.55 (SD 0.24). For 164 eyes (15.2%), the current spectacle correction was insufficient. An untreated cataract was present in 145 eyes (13.4%), 89 eyes (8.2%) were receiving glaucoma treatment, and 7 eyes had a decompensated glaucoma. Dry age-related macular degeneration (AMD) appeared in 276 eyes (25.6%), 12 eyes (1.1%) had wet AMD, and 24 eyes (11.0%) among patients with diabetes showed signs of diabetic retinopathy. Other pathologies were uncommon. CONCLUSION Residents of nursery homes, who are unable to attend regular ophthalmological control, show various treatable ophthalmological conditions, including cataracts, glaucoma, and retinal pathologies. Screening with a novel telemedicine service allows for the identification of treatable conditions and careful planning and referral of patients to appropriate clinics having the necessary infrastructure for this particular population.

Abstract
BACKGROUND After the introduction of a "treat-and-extend" regimen (T&E) with aflibercept for exudative age-related macular degeneration, naive eyes were compared with eyes pretreated with a "pro re nata" scheme (PRN). PATIENTS AND METHODS The Ethics Committee of Eastern Switzerland approved the retrospective single-centre study (EKOS20/084, project ID: 2020-01193). The study included 342 eyes of 303 patients newly treated with or switched to T&E between January 2018 and March 2018 at the Eye Clinic of the Cantonal Hospital St. Gallen. The gender distribution of the treated eyes was 63.5% (n = 217) female and 36.5% (n = 125) male. The mean age was 81.6 years (SD = 8.6 years). The collective was divided into three groups: 1) naive, untreated eyes (n = 92), 2) eyes with ≤ 6 previous treatments with PRN (n = 37), 3) eyes with > 6 previous treatments with PRN (n = 213). The following parameters were analysed up to December 2019: the evolution of visual acuity, the number of intravitreal injections, the number of recurrences, the duration of the follow-up, the dropout rate, and the duration of the last treatment interval. RESULTS During the observation period, group 1 showed a statistically significant improvement in visual acuity of + 1.5 ETDRS, while groups 2 and 3 showed a decrease in visual acuity of - 2.9 and - 3.7 ETDRS, respectively. Group 1 had better development of visual acuity than groups 2 and 3 (p = 0.005), while groups 2 and 3 were not significantly different (p = 0.92). The other parameters examined in the three groups did not differ significantly between groups. CONCLUSIONS Treatment with aflibercept in T&E shows significantly better visual acuity in naive eyes than in eyes pretreated with PRN.

Abstract
AIMS The arrival of anti-vascular endothelial growth factor (anti-VEGF) therapies represented a treatment shift for several ophthalmological disorders and led to an increasing number of patients undergoing intravitreal injections. The aims of this observational study were to assess the expansion of anti-VEGF intravitreal injections in the Portuguese National Health System (NHS) and to identify factors correlated with geographical variations in episode rates. METHODS Administrative database on discharge from Portuguese NHS hospitals was analysed for annual values and rates of intravitreal anti-VEGF injections at a national and regional level, between 2013 and 2018. RESULTS The number of episodes of anti-VEGF treatment and patients treated increased 16% and 9% per year, respectively, between 2013 and 2018. During the study period around 72% of patients were treated in the Metropolitan areas of Lisbon and Porto and in the Central region. Intravitreal anti-VEGF treatment rates in 2018 were 560 per 100 000 population and presented high variability between municipalities. Higher anti-VEGF treatment rates at the municipality level were associated with shorter distances between their residence and the hospital. At the hospital level, higher ratio of ophthalmologists and higher organisational level were associated with higher anti-VEGF treatment rates. CONCLUSION The number of episodes and patients treated with anti-VEGF injections has been growing in recent years. Proximity to healthcare, more access to ophthalmologists and hospitals with higher organisational levels are associated with higher anti-VEGF treatment rates. Improving access is crucial to reduce regional discrepancies and ensure optimal treatment frequency, which may improve health outcomes.

Anatomical and functional responses to single brolucizumab injection in neovascular age-related macular degeneration patients not responding to antiangiogenics: a case series. Drug Target Insights 2022; 16:6-11. [PMID: 35360670 PMCID: PMC8961812 DOI: 10.33393/dti.2022.2343] [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: 09/24/2021] [Accepted: 03/16/2022] [Indexed: 11/24/2022] Open
Abstract
Introduction: Neovascular age-related macular degeneration (nAMD) is treated with antivascular endothelial growth factor (anti-VEGF) drugs. However, resistance to anti-VEGF therapy is observed in some patients. Brolucizumab is a new-generation anti-VEGF drug for the treatment of nAMD, with proven efficacy in fluid resolution and long-lasting effects. Methods: We report here a case series of nAMD patients not responding to previous anti-VEGF therapy showing anatomical and functional response to a single intravitreal injection of brolucizumab. Results: Nine patients with nAMD, undergoing treatment with anti-VEGF therapy (aflibercept, bevacizumab, or ranibizumab) but with either fluid persistence or frequent fluid recurrences in retinal compartments, were switched to intravitreal brolucizumab and examined 4 weeks postinjection. No signs of active disease were observed in all but one patient, with complete retinal fluid resolution in seven patients. Central macular thickness and visual acuity significantly improved, and changes were sustained for up to 12 weeks in a subset of three patients. No adverse reactions were observed. Conclusions: This new anti-VEGF drug showed great efficacy since the first week from the injection with a significative reduction of subretinal fluid and rapid improvement of visual acuity. In conclusion, brolucizumab administered intravitreally appears to be an effective treatment in nAMD patients, leading to both early anatomical and functional improvements.

Abstract
PURPOSE To assess the effect of clinical factors on the development and progression of atrophy and fibrosis in patients with neovascular age-related macular degeneration (nAMD) receiving long-term treatment in the real world. METHODS An ambispective 36-month multicentre study, involving 359 nAMD patients from 17 Spanish hospitals treated according to the Spanish Vitreoretinal Society guidelines, was designed. The influence of demographic and clinical factors, including the presence and location of retinal fluid, on best-corrected visual acuity (BCVA) and progression to atrophy and/or fibrosis were analysed. RESULTS After 36 months of follow-up and an average of 13.8 anti-VEGF intravitreal injections, the average BCVA gain was +1.5 letters, and atrophy and/or fibrosis were present in 54.8% of nAMD patients (OR = 8.54, 95% CI = 5.85-12.47, compared to baseline). Atrophy was associated with basal intraretinal fluid (IRF) (OR = 1.87, 95% CI = 1.09-3.20), whereas basal subretinal fluid (SRF) was associated with a lower rate of atrophy (OR = 0.40, 95% CI = 0.23-0.71) and its progression (OR = 0.44, 95% CI = 0.26-0.75), leading to a slow progression rate (OR = 0.34, 95% CI = 0.14-0.83). Fibrosis development and progression were related to IRF at any visit (p < 0.001). In contrast, 36-month SRF was related to a lower rate of fibrosis (OR = 0.49, 95% CI = 0.29-0.81) and its progression (OR = 0.50, 95% CI = 0.31-0.81). CONCLUSION Atrophy and/or fibrosis were present in 1 of 2 nAMD patients treated for 3 years. Both, especially fibrosis, lead to vision loss. Subretinal fluid (SRF) was associated with good visual outcomes and lower rates of atrophy and fibrosis, whereas IRF yields worse visual results and a higher risk of atrophy and especially fibrosis in routine clinical practice.

Abstract
This Italian retrospective study aimed to analyze the pharmaco-utilization of anti-VEGF drugs and health care costs among patients with wet age-related macular degeneration (wAMD) or other ocular diseases. A retrospective analysis was performed on administrative databases of Italian entities covering approximately six million individuals. Across January 2010–December 2017, patients aged ≥50 years with a prescription of intravitreal anti-VEGFs were included as “wAMD” patients [by wAMD hospitalization or intravitreal injections] or as “other ocular diseases” patients [by hospitalization for other ocular disorders or intravitreal injections, with concomitant diabetes diagnosis or dexamethasone treatment]. The date of first matching of inclusion criteria was index-date. wAMD-cohort. Overall, 3879 patients were included; at index-date, 82.2% were treated with Ranibizumab, 15.8% with Aflibercept, and 2% with Pegaptanib. During the follow-up, the mean/annual anti-VEGF prescription [3.6 (first-year)–0.8 (third-year)] and the total expenditure [5799.84 € (first-year)–3212.84 € (third-year)] decreased. Other ocular diseases-cohort. Overall, 2646 patients were enclosed; 85.9% were treated with Ranibizumab, 13.5% with Aflibercept, and 0.6% with Pegaptanib. During the follow-up, the mean/annual anti-VEGF prescription [3.3 (first-year)–0.5 (third-year)] and the total cost [7196.83 € (first-year)–5162.68 € (third-year)] decreased. This observational study highlighted a decline in anti-VEGF prescriptions over time in both cohorts, suggesting a trend of under-treatment that could worsen the patients’ clinical outcomes and increase health care resource consumption.

A model to quantify the influence of treatment patterns and optimize outcomes in nAMD. Sci Rep 2022; 12:2789.

Abstract
Neovascular age-related macular degeneration (nAMD) is a progressive retinal disease that often leads to severe and permanent vision loss. Early initiation of anti-vascular endothelial growth factor (anti-VEGF) therapy has been shown to preserve vision in nAMD patients. Concurrently, treatment outcomes in real-world are inferior to those reported in clinical trials. The most likely reasons observed are fewer treatment-intensity in routine clinical practice than in clinical trials. The other possibility could be the delay in starting treatment and the re-treatment interval. Although a negative impact of aforementioned parameters seems obvious, quantitative impact measures remain elusive in a real-world setting due to a lack of an ‘optimal treatment’ control group. To overcome this shortcoming, we developed, validated, and applied a model to assess and quantify the impact of anti-VEGF administration variables on visual acuity development in a prospective nAMD patient cohort. The model was further applied to probe the impact of the COVID-19 pandemic on visual progressions in nAMD patients. The presented model paves the way to systematically explore and evaluate realistic interventions in the current treatment paradigm, that can be adopted in routine clinical care.

Abstract
INTRODUCTION To present real-world outcomes of neovascular age-related macular degeneration (nAMD) management in Thailand. METHODS This multicenter retrospective study reviewed medical records of naive nAMD patients diagnosed from 1 January 2016 until 31 December 2018. The patients received at least one intravitreal anti-vascular endothelial growth factor (VEGF) treatment and had captured visual acuity (VA) at baseline and at month 12. Treatment outcomes were assessed at month 12, 24, and 36. The primary outcome was a mean change in VA from baseline to month 12. RESULTS Five hundred seventy-two (572) eyes were included in this study and of these eyes, 222 and 96 had 2- and 3-year follow-up periods, respectively. At month 12, the mean improvement of VA (ETDRS letter) was six letters (P < 0.0001), and central retinal thickness (CRT) decreased on average by 104 microns (P < 0.0001). However, visual improvement by 0.1 letters at month 36 did not show statistical significance. The presence of fluid was found in approximately half of patients throughout the study period (45.98%, 48.85%, and 50.91% at month 12, 24, and 36, respectively). Mean number of injections (SD) was 6.06 (3.00), 3.44 (2.94), and 2.71 (3.07) for years 1, 2, and 3, respectively. The mean number of visits (SD) in year 1 was 9.01 (2.60) and declined to 5.67 (2.69) in year 2 and 4.93 (2.49) in year 3. Patients who had an average injection interval of ≤ 8 weeks were 74.46% in year 1, 51.28% in year 2, and 45.24 in year 3; 35.31% of patients were lost to follow-up. CONCLUSIONS This analysis reflects real-world nAMD management with significant improvement of outcomes. At the same time, the study reveals unmet needs in anti-VEGF therapy in nAMD including persistent disease activities, inadequacy of available treatment, and lack of treatment adherence leading to visual deterioration in the long-term.

Abstract
PURPOSE The purpose of this study is to report the 24-month outcomes of a pro re nata (PRN) compared with a treat and extend (T&E) regimen in patients previously treated for neovascular age-related macular degeneration (nAMD). METHODS This was a 2-year prospective, single-center study. Previously treated patients for nAMD were randomized into two regimen groups: T&E and PRN groups. Main outcome measured was change in best corrected visual acuity (BCVA) from baseline to month 24. Secondary outcomes encompassed anatomical features such as central retinal thickness (CRT), number of intravitreal injections (IVI), and visits required. RESULTS A total of 124 eyes received the T&E (n = 61) or PRN (n = 63) regimen. At month 24, the mean BCVA change was -4.4 early treatment diabetic retinopathy study (ETDRS) letters (T&E) and -3.4 ETDRS letters (PRN), with a difference of +1.1 ETDRS letters (95% CI [-2.25]; p = 0.006). The mean change in CRT was -10.6 µm (T&E) and -7.9 µm (PRN), with a difference of +2.6 µm (95% CI [+19.2]; p = 0.004). The T&E group had received a mean of +4.6 more injections (95% CI [-7.06; -2.12]; p < 0.001) at month 24. CONCLUSION There was statistically proven non-inferiority between the PRN and T&E regimens in terms of visual and anatomical outcomes at 24 months, with significantly more IVI administered in the T&E regimen.

Antivascular endothelial growth factor agents for wet age-related macular degeneration: an IRIS registry analysis. CANADIAN JOURNAL OF OPHTHALMOLOGY 2021; 58:252-261. [PMID: 34863677 DOI: 10.1016/j.jcjo.2021.10.008] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 10/22/2021] [Accepted: 10/28/2021] [Indexed: 11/21/2022]
Abstract
OBJECTIVE To evaluate treatment patterns and outcomes of patients in the United States who received antivascular endothelial growth factor (anti-VEGF) agents for wet age-related macular degeneration (AMD). DESIGN Retrospective study PARTICIPANTS: Patients with wet AMD. METHODS Using the Intelligent Research in Sight Registry, we studied patients with wet AMD who received ≥1 anti-VEGF injection, who were ≥50 years old, and with ≥1.5 years of follow-up. Patients were grouped based on follow-up duration (in years): ≥1.5 (cohort 1), ≥2.5 (cohort 2), and ≥3.5 (cohort 3). RESULTS Patient characteristics were similar between treatment groups. 36.8%, 34.5%, and 39.2% of ranibizumab, aflibercept, and all anti-VEGF eyes, respectively, had an injection interval <8 weeks in length at the end of year 1. Results were similar at year 2 and 3. In cohorts 1-3, visual acuity (VA) changes from baseline ranged from 0.3 to 0.7 (year 1), -1.3 to -1.7 (year 2), and -2.8 to -3.1 (year 3) Early Treatment Diabetic Retinopathy Study letters. By the end of year 3, 41%, 39%, and 42% of ranibizumab, aflibercept, and all anti-VEGF eyes, respectively, had discontinued treatment (no injection for >6 months). CONCLUSION Approximately one-third of eyes had injection intervals <8 weeks in length at the end of year 1. VA was slightly better at the end of year 1 and declined after the first year despite treatment. By the end of year 3, more than one-third of eyes had discontinued treatment. Given the high treatment burden, wet AMD patients may benefit from more durable approaches that require less frequent dosing.

Three-Year Outcomes of Neovascular Age-Related Macular Degeneration in Eyes That Do Not Develop Macular Atrophy or Subretinal Fibrosis. Transl Vis Sci Technol 2021; 10:5.

Abstract
Purpose To report the 36-month treatment outcomes of eyes with neovascular age-related macular degeneration (nAMD) receiving vascular endothelial growth factor (VEGF) inhibitors in daily practice who did not develop either subretinal fibrosis (SRFi) or macular atrophy (MA). Methods This is a retrospective analysis of data from the Fight Retinal Blindness registry. Treatment-naïve eyes starting intravitreal injection of VEGF inhibitors for nAMD from January 1, 2010, to September 1, 2017, and did not have SRFI and MA at baseline were tracked. Results We identified 2478 eligible eyes, of which 1712 eyes did not develop SRFi or MA, 291 developed extrafoveal SRFI or MA, and 475 developed subfoveal SRFi or MA over 36 months. The estimated visual acuity stabilized from 6 months to 36 months in eyes that did not develop SRFI or MA with a mean (95% confidence interval [CI]) change in VA of −1 (−2, 0) letters, whereas eyes that developed extrafoveal (−3 [−5, −2] letters) or subfoveal (−10 [−11, −8] letters) SRFi or MA declined in vision in the same period. Eyes with no or extrafoveal SRFi or MA over 36 months were more likely to maintain their visual improvement from six months to 36 months (odds ratio [OR; 95% CI] = 2.3 [1.5, 3.3] for absence vs. subfoveal SRFi or MA, P ≤ 0.01 and OR = 2.0 [1.2, 3.4] for extrafoveal vs. subfoveal MA or SRFi, P = 0.01). Conclusions Treatment-naïve nAMD eyes receiving VEGF inhibitors maintain their initial six-month visual improvement over three years if they do not develop SRFI or MA. Translational Relevance The nAMD is still a major cause of blindness despite antiangiogenic treatments. We found that eyes that did not develop subretinal fibrosis or macular atrophy maintained their initial vision improvement for at least three years, suggesting that identifying treatments for these complications is the final barrier to achieving excellent outcomes in nAMD.
