Efficacy, Durability and Safety of Faricimab in Neovascular Age-Related Macular Degeneration and Diabetic Macular Oedema: Lessons Learned from Registration Trials. Ophthalmol Ther 2023; 12:2253-2264. [PMID: 37410309 PMCID: PMC10441964 DOI: 10.1007/s40123-023-00753-6] [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: 03/27/2023] [Accepted: 06/08/2023] [Indexed: 07/07/2023] Open
Abstract
INTRODUCTION This review aims to assess the efficacy, durability and safety of faricimab-a dual vascular endothelial growth factor and angiopoietin 2 inhibitor-in patients with neovascular age-related macular degeneration (nAMD) and diabetic macula oedema (DMO). It summarises the findings of current studies on faricimab and discusses whether this new drug may fill a gap in current treatment options. METHODS We performed a search of the PubMed, Cochrane, Web of Science and EMBASE databases for publications on faricimab between 29 November 2022 and 10 May 2023, and a search of ClinicalTrials.gov for the protocols on clinical trials for this review. We included clinical trials, case-control studies and observational studies. RESULTS In phase 3 trials of nAMD, the efficacy of faricimab was non-inferior to aflibercept (+ 5.8-6.6 vs. + 5.1-6.6 Early Treatment Diabetic Retinopathy Study [ETDRS] letters). At study end, 80% of faricimab-treated patients were on ≥ 12-week dosing intervals, and 44.9-45.7% of faricimab-treated patients were on 16-week dosing intervals. Total adverse events, as well as serious ocular adverse events, were comparable between groups. In phase 3 trials of DMO, efficacy of faricimab was non-inferior to aflibercept (+ 10.7-11.8 vs. + 10.3-10.9 ETDRS letters). At study end, > 70% of patients in the personalised treatment interval faricimab group were on ≥ 12-week dosing intervals, and 51-53% were on 16-week dosing intervals. Total adverse events were comparable between groups, although the rate of serious ocular adverse events was higher in the faricimab groups than in the aflibercept groups (1.9-3.1% vs. 0.6-1.9%, respectively). In real-world studies of treatment-resistant nAMD or DMO, faricimab demonstrated superior efficacy compared to aflibercept. In a real-world study of mostly previously treated nAMD, faricimab demonstrated some efficacy. CONCLUSION Faricimab demonstrated non-inferior to superior efficacy, strong durability and acceptable safety in treatment-naïve nAMD and mostly treatment-naïve DMO, as well as superior efficacy in treatment-resistant nAMD and DMO. However, further research is needed on faricimab in real-world settings.

Huang X, Zhang L, Fu Y, Zhang M, Yang Q, Peng J. Rethinking the potential and necessity of drug delivery systems in neovascular age-related macular degeneration therapy. Front Bioeng Biotechnol 2023; 11:1199922. [PMID: 37288355 PMCID: PMC10242387 DOI: 10.3389/fbioe.2023.1199922] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Accepted: 05/09/2023] [Indexed: 06/09/2023] Open
Abstract
Age-related macular degeneration (AMD) is the predominant threat to human vision and ultimately results in blindness. With the increase in the aging population, it has become a more crucial issue to human health. AMD is a multifactorial disease with the unique feature of uncontrollable angiogenesis during initiation and progression. Although increasing evidence indicates that AMD is largely hereditary, the predominant efficient treatment is antiangiogenesis, which mainly involves VEGF and HIF-α as therapeutic targets. The repeated administration of this treatment over the long term, generally through intravitreal injection, has called for the introduction of long-term drug delivery systems, which are expected to be achieved by biomaterials. However, the clinical results of the port delivery system indicate that the optimization of medical devices toward prolonging the activities of therapeutic biologics in AMD therapy seems more promising. These results indicate that we should rethink the possibility and potential of biomaterials as drug delivery systems in achieving long-term, sustained inhibition of angiogenesis in AMD therapy. In this review, the etiology, categorization, risk factors, pathogenesis, and current clinical treatments of AMD are briefly introduced. Next, the development status of long-term drug delivery systems is discussed, and the drawbacks and shortages of these systems are emphasized. By comprehensively considering the pathological aspect and the recent application of drug delivery systems in AMD therapy, we hope to find a better solution for the further development of long-term therapeutic strategies for AMD.

Hertzberg SNW, Jørstad ØK, Petrovski BÉ, Bragadottir R, Steffensen LA, Moe MC, Burger EA, Petrovski G. Transition from Laser to Intravitreal Injections for Diabetic Retinopathy: Hospital Utilization and Costs from an Extended Healthcare Perspective. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:12603. [PMID: 36231903 PMCID: PMC9564656 DOI: 10.3390/ijerph191912603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 09/26/2022] [Accepted: 09/28/2022] [Indexed: 06/16/2023]
Abstract
PURPOSE To describe the trends in hospital utilization and economic outcomes associated with the transition from laser to intravitreal injection (IVI) therapy for diabetic retinopathy (DR) at Oslo University Hospital (OUH), which provides the largest retina service in Norway. METHODS This descriptive study analyzed hospital administrative data and determined the average utilization and treatment proportions of laser therapy, IVIs and vitrectomy for each patient per year. The Chi-square test was used to compare resource use between treatment groups. From an extended healthcare perspective, the annual cost per patient was calculated using Norwegian tariff data from 2020 and the National Medication Price Registry for patients seen between 2010 and 2018. Bootstrapping was performed to generate 95% confidence intervals for the cost per patient per year. RESULTS Among the 1838 (41% female) patients treated for DR between 2005 and 2018, OUH provided on average 1.09 laser treatments per DR patient and 0.54 vitrectomies per DR patient in 2005, whose utilization declined to 0.54 and 0.05 treatments per DR patient, respectively, by 2018. Laser treatments declined from 64% to 10%, while vitrectomies declined from 32% to 1%. In contrast, IVI treatments increased from 4.5% to 89% of the total share, representing an average increase, from 0.08 injections per patient in 2005 to 4.73 injections per patient in 2018. Both the increasing number of DR patients and the shift in the type of treatment increased the economic costs of treating DR from a total of EUR 0.605 million (EUR 2935 per patient) in 2010 to EUR 2.240 million (EUR 3665 per patient) in 2018, with IVIs contributing considerably to these costs. CONCLUSIONS Despite the decline in the use of vitrectomies, the transition from laser to IVI therapy for DR increased the healthcare resource utilization and economic costs of its treatment over the observed time. A main cost driver was the need for long-term IVIs, in addition to the drug cost itself. Trade-offs can be achieved through effective alternative IVI delivery or appropriate drug choice that balances patient needs with the economic burden of treating DR.

Abstract
OBJECTIVES To investigate the eligibility of a real-world neovascular age-related macular degeneration (nAMD) population for the TENAYA and LUCERNE trials (testing faricimab), and to compare the eligible real-world patients to trial participants. DESIGN, SETTINGS AND PARTICIPANTS In this retrospective cross-sectional study, we used data from the Swedish Macula Registry (SMR) between 1 January 2017 and 31 December 2020. Persons were eligible if they fulfilled the main inclusion criteria in TENAYA and LUCERNE: (1) nAMD diagnosis, (2) treatment naïve, (3) ≥50 years and (4) best-corrected visual acuity (BCVA) of 78-24 letters. MAIN OUTCOME MEASURES Characteristics at the original visit of the eligible SMR population and baseline data from the clinical trials were compared. RESULTS In total, 27 962 individuals with nAMD were registered in SMR. A total of 15 399 (55%) individuals were treatment naïve; of these, 15 368 (55%) were ≥50 years and 13 265 (47%) also had BCVA of 78-24 letters and fulfilled eligibility. Among treatment-naïve individuals, 86% were eligible and the BCVA criterion was the most common reason for non-eligibility. The eligible SMR population was significantly older than either TENAYA or LUCERNE. SMR included more women and patients with worse visual acuity than TENAYA, while SMR patients were diagnosed more quickly than LUCERNE. CONCLUSIONS Almost half of the real-world nAMD population in SMR fulfilled the main inclusion criteria of the TENAYA and LUCERNE trials. Among treatment-naïve individuals, 86% were eligible. Marginally differences were shown between the eligible SMR population and the trial populations. The SMR population were older and more similar to the population in LUCERNE than TENAYA.
