Abstract
PURPOSE To evaluate the 1-year treatment outcomes of intravitreal aflibercept injections (IVA) using a treat-and-extend regimen for polypoidal choroidal vasculopathy (PCV). METHODS Thirty-seven eyes with treatment-naive PCV treated with IVA using a treat-and-extend regimen for 1 year were reviewed retrospectively. The main outcome measures were changes in the best-corrected visual acuity (BCVA) and central retinal thickness (CRT), and the treatment interval at 1 year. The predictive factors for patients who could not continue to extend the treatment interval because of poor response to IVA or recurrence were analyzed. RESULTS The mean logarithm of the minimum angle of resolution BCVA improved from 0.37 at baseline to 0.21 at 1 year (P < 0.001). The mean CRT decreased from 342.3 μm at baseline to 196.6 μm at 1 year (P < 0.001). The mean treatment interval was 9.7 weeks at 1 year (4 weeks in 11 eyes [29.7%], 6 weeks in 1 eye [2.7%], 8 weeks in 2 eyes [5.4%], 10 weeks in 1 eye [2.7%], and 12 weeks in 22 eyes [59.5%]). A larger number of polypoidal lesions at baseline was predictive for patients who could not continue to extend the treatment interval. CONCLUSIONS IVA using a treat-and-extend regimen is effective for improving BCVA and CRT in eyes with PCV.

Ophthalmology 2016; 124:74-81. [PMID: 27836430 DOI: 10.1016/j.ophtha.2016.09.021] [Citation(s) in RCA: 61] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2016] [Revised: 09/15/2016] [Accepted: 09/16/2016] [Indexed: 10/20/2022] Open
Abstract
PURPOSE To compare monthly dosing with a treat and extend algorithm using ranibizumab 0.3 mg with and without angiography-guided macular laser photocoagulation for center-involving diabetic macular edema (DME). DESIGN Multicenter, prospective, randomized clinical trial. PARTICIPANTS A total of 150 eyes from 116 subjects were randomized into 3 cohorts: Monthly (n = 30), TReat and EXtend without macular laser photocoagulation (TREX; n = 60), and treat and extend with angiography-GuIded macular LAser photocoagulation (GILA; n = 60). METHODS Monthly cohort eyes received ranibizumab 0.3 mg every 4 weeks. Eyes in the TREX and GILA cohorts received 4 monthly injections of ranibizumab 0.3 mg followed by a treat and extend algorithm based on disease activity. Eyes in the GILA cohort also received angiography-guided macular laser photocoagulation at month 1 and again every 3 months for microaneurysm leakage. MAIN OUTCOME MEASURES Change in mean best-corrected visual acuity (BCVA), mean central retinal thickness (CRT), number of injections from baseline to 1 year, and percentage gaining/losing 2 and 3 lines of vision. RESULTS Baseline demographics were well balanced among the cohorts. A total of 137 eyes (91%) completed the 1-year end point visit. At 1 year, the mean BCVA improved by 8.6, 9.6, and 9.5 letters in the Monthly, TREX, and GILA cohorts, respectively (P = 0.8). There was no significant difference between the cohorts in the percentage gaining/losing 2 and 3 lines of vision. The CRT improved by 123 μm, 146 μm, and 166 μm in the Monthly, TREX, and GILA cohorts, respectively (P = 0.47). The mean number of macular laser treatments in the GILA cohort at 1 year was 2.9 (range, 1-4). The number of injections was significantly reduced in both the TREX (10.7) and GILA (10.1) cohorts compared with the Monthly cohort (13.1, P < 0.001). There were no cases of endophthalmitis, and the total incidence of Anti-Platelet Trialists' Collaboration events was 4.7%. CONCLUSIONS This prospective, randomized trial found that treat and extend dosing of ranibizumab 0.3 mg with and without angiography-guided macular laser photocoagulation significantly decreased the number of injections given while providing similar visual and anatomic outcomes compared with monthly dosing at 1 year. Adding angiography-guided laser photocoagulation to this dosing algorithm did not significantly improve outcomes at 1 year.

Abstract
INTRODUCTION Wet age-related macular degeneration (AMD) is a chronic eye condition that causes severe deterioration of vision and even blindness. Current wet AMD treatment in the UK involves the vascular endothelial growth factor inhibitors ranibizumab and aflibercept. Patients with wet AMD require frequent and long-term monitoring for treatment to be effective, contributing to a substantial resource burden at wet AMD centers. The European license for ranibizumab was recently updated with an individualized 'treat and extend' (T&E) regimen, comprising a structured monitoring and treatment protocol. This study evaluated the cost-effectiveness of ranibizumab T&E versus aflibercept within a UK setting. METHODS An individual patient-level simulation model was developed utilizing treatment effects from a network meta-analysis of randomized controlled trials. The model was conducted from a UK National Health Service (NHS) perspective over a lifetime horizon and the base case utilized probabilistic sensitivity analysis to assess uncertainty in the model. Additional scenario analyses were conducted to assess the impact of changes to the model inputs. RESULTS Ranibizumab T&E was found to be more effective and less costly than aflibercept, providing, on average, an additional 1.058 quality-adjusted life years (QALYs) and a cost-saving of £19,604 over a lifetime horizon. At list price, ranibizumab T&E was found to be cost-effective versus aflibercept in 100% of simulations at a willingness-to-pay threshold of £20,000 per QALY. The robustness of the results was tested in several scenario analyses; ranibizumab T&E was found to be more effective, and less costly, than aflibercept in the vast majority of cases. CONCLUSION This evaluation suggests that treating patients with ranibizumab according to the T&E regimen could be a better use of NHS resources than aflibercept, and could, therefore, be considered as a first-line regimen for patients with wet AMD in the UK.

Abstract
In the last decade, a number of prospective clinical trials with carefully designed study protocols have been conducted for the treatment of neovascular age-related macular degeneration (AMD). These landmark clinical trials such as ANCHOR and MARINA and, more recently, the Comparison of AMD Treatment Trials and VIEW studies have revolutionized the management of neovascular AMD. While AMD continues to remain a leading cause of severe visual loss worldwide, advances in pharmacotherapeutics have led to substantial improvements in the outcome of these patients. The introduction of anti-vascular endothelial growth factor agents has resulted in improvement of visual outcomes and has had a positive impact on the quality of life among elderly population. While the contemporary management of neovascular AMD has been successful in tremendously reducing the visual morbidity, the financial burden of therapy has increased exponentially. To overcome these challenges, newer pharmacologic agents are evaluated for their efficacy and safety in AMD. Ground-breaking advances in bench to bedside research have led to discovery of new pathways that appear to be viable targets for preventing visual loss in AMD. In this review, study designs and results of landmark clinical trials in AMD from the past decade have been summarized.

Abstract
PURPOSE To explain the pivotal role optical coherence tomography (OCT) imaging had in the development of antiangiogenic therapies for the treatment of neovascular age-related macular degeneration (nvAMD). METHODS A historical literature review was combined with personal perspectives from the introduction of OCT imaging and the early clinical use of vascular endothelial growth factor (VEGF) inhibitors. RESULTS At the time that OCT emerged, the gold standard for imaging of nvAMD was fluorescein angiography (FA), a time-consuming, dye-based, invasive technique that provided en face images of the retina and was used to characterize leakage, perfusion status, and the types of macular neovascularization (MNV). In comparison, OCT imaging was a fast, safe, noninvasive technique that complemented FA imaging by providing cross-sectional images of the macula. OCT was able to visualize and quantify the macular fluid that was associated with the presence of excess VEGF, which was identified by intraretinal fluid, subretinal fluid, and fluid under the retinal pigment epithelium (RPE). Clinicians quickly appreciated the benefits of OCT imaging for following macular fluid after anti-VEGF therapy. By observing the qualitative and quantitative changes in macular fluid depicted by OCT imaging, clinicians were empowered to compare anti-VEGF drugs and move from fixed-dosing regimens to patient-specific dosing strategies requiring fewer injections. CONCLUSIONS Optical coherence tomography imaging was adopted as a VEGF-meter, a method to detect excess VEGF, and evolved to become the gold standard imaging strategy for diagnosing nvAMD, assessing treatment responses to anti-VEGF drugs, deciding when to re-treat, and evaluating disease progression.

Abstract
OBJECTIVE To describe the 1-year efficacy of aflibercept in Japanese patients with age-related macular degeneration (AMD) who were resistant to ranibizumab treatment. DESIGN Retrospective case series. PARTICIPANTS Fourteen consecutive eyes of 14 patients with AMD were enrolled who had no substantial response or developed resistance to intravitreal ranibizumab injections. METHODS All patients were subcategorized into one of two subtypes of AMD: seven patients with occult choroidal neovascularization (CNV) and seven with polypoidal choroidal vasculopathy (PCV). Serial intravitreal aflibercept (IVA) injections were administered. Comprehensive ophthalmic examinations, including optical coherence tomography, were conducted at baseline and at follow-up examinations at 1, 3, 6, and 12 months after the initial IVA injection. The best-corrected visual acuity converted to logarithm of the minimum angle of resolution (logMAR) and central macular thickness (CMT) at each follow-up visit were compared with the baseline values. The anatomic response was also assessed with absorption or reduction of fluid in the subretina or subretinal pigment epithelial space. RESULTS The logMAR best-corrected visual acuity improved significantly at 3, 6, and 12 months in the total cohort: at 3 and 6 months in patients with occult CNV and at 3 and 12 months in patients with PCV. The CMT decreased significantly at all follow-up visits in the total cohort as well as in both subtypes, except for the CMT at 6 months in PCV patients. The anatomic improvement was also demonstrated in all cases, and pigment epithelial detachments tended to be resolved more rapidly in patients with PCV than in patients with occult CNV. CONCLUSION Conversion to IVA was effective in patients with AMD resistant to ranibizumab, showing rapid morphologic improvement. The logMAR visual acuity was raised significantly within 12 months, and the clinical course of visual acuity improvement may differ according to the AMD subtypes.

Abstract
PURPOSE The objective of our study was to investigate preferences of patients with neovascular age-related macular degeneration (nAMD) for different anti-vascular endothelial growth factor (VEGF) treatment schemes. DESIGN We used a discrete choice experiment (DCE) design as part of a telephone interview. PARTICIPANTS Patients with nAMD aged at least 50 years were included in the study. METHODS Telephone interviews were done between November 2012 and October 2013. MAIN OUTCOME MEASURES In our DCE survey, we measured patient preferences toward specific levels of attributes that describe different options in the everyday intravitreal injection treatment setting: (1) treatment scheme; (2) change of visual acuity (VA); and (3) time the patient needs for each visit to the eye specialist. RESULTS A total of 284 patients with nAMD with a mean age of 77.4±7.1 years (women: 59.9%) completed the DCE interviews. Of them, 22.9% had poor VA at study inclusion, 54.9% had moderate VA, and 14.1% had good VA; VA was not available for 8.1% of the patients. Generally, patients preferred the attribute levels "improvement in VA" and "short time per specialist visit." The results for the attribute "treatment scheme" were inconclusive because none of the attribute levels (injections every 4 weeks, every 8 weeks, and pro re nata) were associated with statistically significant utility differences. This also mirrors the relative importance of the different attributes in patient decisions: "Change of VA" influenced decision making for a treatment option in 73.6% of cases; "waiting, treatment, and travel time" influenced decision making in 21.0% of cases; and "treatment scheme" influenced decision making for a treatment option in 5.4% of cases. To obtain improved VA instead of a worsening VA, patients in our study stated to be willing to accept a very long time needed per physician visit of 21.2 hours (8.5 hours for improved rather than stable VA and 12.7 hours for stable VA rather than worsening VA). CONCLUSIONS To prevent deterioration of VA, patients with nAMD seem to be willing to accept a high treatment burden with regular intravitreal injections at short intervals and long periods of waiting, treatment, and traveling for their consultations.
