Long Intervals between Intravitreal Injections Using a Treat-and-Extend Protocol in a Real-Life Context in AMD: The LIRE Study. Ophthalmologica 2023; 247:44-57. [PMID: 38104545 PMCID: PMC10836925 DOI: 10.1159/000535806] [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: 07/26/2023] [Accepted: 12/11/2023] [Indexed: 12/19/2023]
Abstract
INTRODUCTION The aim of the study was to assess the outcome of long treat-and-extend (TE) anti-VEGF intravitreal injection (IVI) intervals (≥every 12 weeks [Q12W]) in neovascular age-related macular degeneration (nAMD). The aims of this retrospective study were to determine the proportion of nAMD eyes treated ≥ Q12W, to analyze their longitudinal, functional, and anatomical outcomes, and to compare functional and anatomical outcomes between eyes that rapidly versus slowly reached a Q12W regimen and between eyes directly treated with versus initiating lately the TE regimen. METHODS All patients receiving IVIs for nAMD were screened. The longitudinal, functional, and anatomical characteristics of Q12W-treated eyes were reported at different timepoints. RESULTS Ninety-one eyes were included (38% of our total nAMD cohort). The mean TE regimen time to reach a Q12W interval was 20.1 ± 16.2 months. During this time, a mean number of 12.1 ± 9.3 IVIs were needed. The mean best-corrected visual acuity was 68 letters at the time of diagnosis and was maintained (p > 0.05). Eyes that rapidly reached a Q12W interval had a shorter follow-up before TE regimen initiation (p = 0.04) and received fewer IVIs (p = 0.02) than eyes that slowly reached a Q12W interval. Eyes directly treated with the TE regimen reached a Q12W interval more rapidly than eyes with late TE initiation. The neovascularization subtype was not a predictor of outcome in TE-treated eyes. CONCLUSION ≥Q12W eyes represent an important part of the nAMD population in our real-life study. No baseline anatomical characteristics were associated with the outcome under a TE regimen, although early TE regimen initiation allowed extending more rapidly the IVI interval.

Brown GC, Brown MM, Gierhart D, Olk RJ. Prevention Surpasses Treatment: 5-year Follow-Up, Cost-Utility, and Cost-Benefit of Zeaxanthin Therapy for Neovascular Age-Related Macular Degeneration. Ophthalmol Ther 2023; 12:2583-2608. [PMID: 37430077 PMCID: PMC10441916 DOI: 10.1007/s40123-023-00742-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Accepted: 05/22/2023] [Indexed: 07/12/2023] Open
Abstract
INTRODUCTION Oral administration of zeaxanthin (Zx) 20 mg daily in patients with unilateral neovascular age-related macular degeneration (nAMD) treated with triple therapy (photodynamic therapy/intravitreal bevacizumab/intravitreal dexamethasone) reduced fellow-eye 2-year nAMD incidence from 23 to 6% (p = 0.02) in a prior clinical trial. We questioned the long-term benefit and thus analyzed case-control 5-year patient data of trial participants and additional participants with 5-year follow-up, also performing cost-utility and cost-benefit analyses. METHODS Consecutive, unilateral nAMD patient outcomes for those taking 20 mg Zx supplementation orally for ≥ 5 years were compared with the Comparison of AMD Treatments Trials (CATT) 5-year historical controls for fellow-eye nAMD conversion. Eleven-year mean life expectancy, cost-utility and cost-benefit models were undertaken employing a 3% discount rate and 2020 US real dollars. RESULTS Among 227 consecutive patients with nAMD/Zx-supplementation, 202 (90%) had 5-year follow-up. The fellow-eye nAMD 5-year conversion incidence using a Kaplan-Meier cumulative event estimate was 22% (49/227), versus 48% (167/348) with CATT control data (p < 0.0001). An 11-year cost-utility model with estimates for years 6-11 demonstrated a 0.42 (7.7%) QALY (quality-adjusted life-year) gain, including 3 months of life saved per patient due to decreased nAMD fellow-eye conversion. This yielded a direct ophthalmic medical cost perspective, incremental cost-utility ratio (CUR) of -$576/QALY and a societal cost perspective CUR of -$125,071/QALY. Zx supplementation for all 2020 US unilateral nAMD cases would have theoretically saved society, primarily patients, $6.0 billion over 11 years, a 1531% return on investment (ROI), or 31.3% annual ROI, on Zx costs. CONCLUSIONS Oral zeaxanthin supplementation for unilateral nAMD patients appears to decrease fellow-eye long-term incidence and is cost-effective and financially rewarding. It is dominant vs. no supplementation in patients presenting with unilateral nAMD. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT01527435.

Aflibercept more effectively weans patients with neovascular age-related macular degeneration off therapy compared with bevacizumab. J Clin Invest 2023; 133:159125. [PMID: 36413411 PMCID: PMC9843049 DOI: 10.1172/jci159125] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Accepted: 11/17/2022] [Indexed: 11/23/2022] Open
Abstract
BACKGROUNDStudies assessing the efficacy of therapies for neovascular age-related macular degeneration (nvAMD) have demonstrated that aflibercept may have a longer treatment interval than its less-expensive alternative, bevacizumab. However, whether this benefit justifies the additional cost of aflibercept remains under debate. We have recently reported that a treat-and-extend-pause/monitor approach can be used to successfully wean 31% of patients with nvAMD off anti-VEGF therapy. Here, we examined whether the choice of therapy influences the outcomes of this approach.METHODSIn this retrospective analysis, 122 eyes of 106 patients with nvAMD underwent 3 consecutive monthly injections with either aflibercept (n = 70) or bevacizumab (n = 52), followed by a treat-and-extend protocol, in which the decision to extend the interval between treatments was based on visual acuity, clinical exam, and the presence or absence of fluid on optical coherence tomography. Eyes that remained stable 12 weeks from their prior treatment were given a 6-week trial of holding further treatment, followed by quarterly monitoring. Treatment was resumed for worsening vision, clinical exam, or optical coherence tomography findings.RESULTSAt the end of 1 year, eyes receiving bevacizumab had similar vision but required more injections (8.7 ± 0.3 treatments vs. 7.2 ± 0.3 treatments) compared with eyes receiving aflibercept. However, eyes treated with aflibercept were almost 3 times more likely to be weaned off treatment (43% vs. 15%) compared with eyes treated with bevacizumab at the end of 1 year.CONCLUSIONThese observations expose an advantage of aflibercept over bevacizumab and have important clinical implications for the selection of therapy for patients with nvAMD.FUNDINGThis work was supported by the National Eye Institute, NIH grants R01EY029750 and R01EY025705, Research to Prevent Blindness, the Alcon Young Investigator Award from the Alcon Research Institute, and the Branna and Irving Sisenwein Professorship in Ophthalmology.

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.

Abstract
PURPOSE To determine the incidence of complete resolution of choroidal neovascular membrane-associated exudation with a single antivascular endothelial growth factor injection in treatment-naive wet age-related macular degeneration patients and its associated characteristics. METHODS Retrospective, observational study of naive wet age-related macular degeneration patients who received antivascular endothelial growth factor therapy with ranibizumab/aflibercept and demonstrated complete resolution of retinal exudation with a single injection. Complete resolution was defined as the total disappearance of the intraretinal fluid, cysts, and subretinal fluid and a return of retinal thickness to <250 μm on spectral-domain optical coherence tomography. All relevant data were collected. Follow-up was scheduled on Days 1, 7, and 30 postoperatively and then monthly, with at least 9 visits mandatory per year if the macula remained fluid free. Appropriate statistical analyses were performed. RESULTS Sixty-three patients (29 men; mean age 67.25 ± 4.40 years) were identified. The mean baseline and final-corrected distance visual acuity was 20/160 and 20/45, respectively. Patients completed a mean of 10.9 follow-up visits per year. Smaller choroidal neovascular membranes (<200 μm), early presentation, better presenting corrected distance visual acuity, subfoveal choroidal neovascular membranes, absence of blood/fibrosis, and use of aflibercept (2 mg) favored resolution with one injection. CONCLUSION A subset (13.76%; 63/458, 95% confidence intervals: 10.73-17.25) of patients with treatment-naive wet age-related macular degeneration demonstrates resolution of choroidal neovascular membrane-associated exudation with a single antivascular endothelial growth factor injection, sustained over 2 years or more. This can lower therapy costs, treatments, office visits, and the potential risk of geographic atrophy.

Yoon WT, Kim JW, Kim CG, Kim JH. Proportion and Reasons for Ineligibility to Re-register for Extended Health Insurance in Neovascular Age-related Macular Degeneration. JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY 2021. [DOI: 10.3341/jkos.2021.62.7.948] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/23/2022]
Abstract
Purpose: To evaluate the proportion and reasons for ineligibility to re-register for extended health insurance at 5 years in patients diagnosed with neovascular age-related macular degeneration (AMD) and registered for extended health insurance. Methods: This retrospective study was performed in patients diagnosed with neovascular AMD and registered for extended health insurance with follow-up for at least 5 years. The criteria for re-registration for extended health insurance were determined along with the ineligibility for re-registration. Results: In total, 263 patients were included in the analysis. Of these, 148 (56.3%) did not satisfy the criteria for re-registration. No active treatment was performed in 98 patients during the last 6 months of the study period (no recurrence, 51 patients; additional treatment was not considered beneficial due to retinal damage even without disciform scar formation, 44 patients). Macular disciform scar formation was noted in 50 patients (33.8%). Older age (p = 0.013), poor visual acuity (p = 0.004), and retinal angiomatous proliferation (p < 0.001) were associated with ineligibility for re-registration due to severe retinal damage. Conclusions: Among the patients who were initially registered for extended health insurance, 56.3% failed to satisfy the re-registration criteria. The primary reason was advanced retinal damage. The results of this study provide useful information for patient education and to establish long-term treatment strategies.
