Abstract
Neovascular age-related macular degeneration (nAMD) is a prevalent cause of permanent vision loss and blindness in the elderly worldwide, with a significant impact on patients' daily lives. However, burdens related to nAMD from the patients' perspective have not been well documented. Here we developed a new questionnaire after eliciting nAMD patients' daily challenges followed by a pilot survey. Seven daily life burden domains were identified, and a quantitative survey was conducted using the questionnaire in the real-world clinic. Of the total 153 participants (mean age, 76.3 ± 8.3 years), 67 (43.8%) had bilateral nAMD, and 79 (52.7%) were classified into severe nAMD according to the best-corrected visual acuity with cut-off value of 0.52 in logMAR. Patients with bilateral and severe nAMD had significantly higher burden scores across all domains. Network models for the bilateral and severe disease subgroups identified the interactions between "activity of daily living" and "hand-eye coordination" and between "use of electronic devices" and "face recognition" domains, which were considered to be important burdens for the patients. These results can advance ophthalmologists' understanding of the impact of nAMD on patients' daily lives and the importance of active and continuing treatment for patients with nAMD.

Abstract
This prospective, multicentre, postmarketing surveillance were conducted to report on the long-term safety and effectiveness of intravitreal aflibercept (IVT-AFL) treatment in clinical practice of Japanese patients with neovascular age-related macular degeneration (nAMD) who newly initiated IVT-AFL treatment. The primary outcomes were the incidence of adverse events (AEs) and of adverse drug reactions (ADRs) over 36 months. Number of injections, timing of ADR occurrence, and some effectiveness index were also summarised. A total of 3,872 patients received 7.2 ± 5.8 (mean ± standard deviation) injections, and AEs occurred in 5.73% of patients. ADRs were reported in 2.76% of patients, with ocular and nonocular ADRs in 2.07% and 0.72% of patients, respectively. Most vitreo-retinal events developed within 6 months of initial IVT-AFL treatment, and most instances of increased intraocular pressure and cerebral infarction developed after 6 months of follow-up. Mean best-corrected visual acuity and central retinal thickness were numerically better throughout the follow-up period compared with baseline. These results indicated acceptable tolerability and effectiveness of IVT-AFL treatment in patients with nAMD in clinical practice in Japan. Information regarding the risk and the timing of ADRs is valuable for safe and effective long-term treatment of patients with nAMD.Trial registration number: NCT01756248.

Impact of Treating Age-Related Macular Degeneration before Visual Function Is Impaired. J Clin Med 2022; 11:jcm11195726. [PMID: 36233594 PMCID: PMC9573686 DOI: 10.3390/jcm11195726] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 09/11/2022] [Accepted: 09/23/2022] [Indexed: 11/23/2022] Open
Abstract
Visual outcomes of age-related macular degeneration (AMD) have substantially improved via anti-vascular endothelial growth factor (anti-VEGF) therapy. However, the treatment effects vary among individuals. Medical charts of 104 eyes (104 patients) with AMD, treated with anti-VEGF drugs and followed up for 12−36 months, were retrospectively analyzed. Logistic regression analyses adjusted for age showed that eyes with an initial best-corrected visual acuity (BCVA) < 0.3 in the logarithm of the minimum angle of resolution (logMAR) were a positive predictor (odds ratio = 3.172; 95% confidence interval [CI] = 1.029−9.783; p = 0.045), and the presence of initial fibrovascular pigment epithelial detachment (PED) was a negative predictor (0.222; 0.078−0.637; p = 0.005) of maintained or improved BCVA at the final visit. Kaplan−Meier survival analysis showed that eyes with an initial BCVA < 0.3 (Cox hazard ratio = 2.947; 95% CI = 1.047−8.289; p = 0.041) had a better survival rate after adjusting for age when failure was defined as a BCVA reduction ≥ 0.2 of logMAR. Eyes with an initial BCVA < 0.3 belonged to younger patients; more frequently had subretinal fluid as an exudative change; and less frequently had intraretinal fluid, submacular hemorrhage, and fibrovascular PED. Initiating anti-VEGF treatment before BCVA declines and advanced lesions develop would afford better visual outcomes for AMD eyes in the real-world clinic, although further analyses are required.

Abstract
Objectives: To evaluate functional and anatomical responses to intravitreal aflibercept (IVA) treatment in newly diagnosed and untreated neovascular age-related macular degeneration (nvAMD) cases and to investigate the effect of baseline lesion characteristics on anatomical responses. Materials and Methods: This prospective, cross-sectional study included a series of 139 eyes of 133 patients that were diagnosed with active nvAMD and had not been treated. All eyes were subjected to complete ophthalmological examination, spectral-domain optical coherence tomography and fluorescein angiography, and 42 eyes also underwent indocyanine green angiography. IVA treatment was performed using a “treat and extend” regimen after 3 injections at 4-6 weeks intervals. Anatomical and functional responses at 4 weeks after the last injection were evaluated in eyes that completed 3 injections and the subgroup of eyes that completed 6 IVA injections. The effect of baseline lesion characteristics on IVA treatment results was also investigated. Results: All 139 eyes included in the study received 3 IVA injections (group 1) and 62 received 6 IVA injections. Both groups showed statistically significant improvement in best-corrected visual acuity (p<0.001 for both). The rate of complete response was 54.6% and 58.0% in groups 1 and 2, respectively. In group 1, the presence of pigment epithelial detachment (PED) and serous PED were identified as negative initial factors (p=0.043, p=0.005, respectively). However, none of the baseline characteristics were significantly associated with anatomical response in group 2. Conclusion: In our study, it was determined that successful anatomical and functional results were achieved with 3 and 6 doses of IVA in eyes with newly-diagnosed and untreated nvAMD. Among baseline characteristics, the presence of PED and serous PED in particular were found to be factors affecting treatment response negatively.

Five-Year Outcome of Aflibercept Monotherapy for Exudative Age-Related Macular Degeneration with Good Baseline Visual Acuity. J Clin Med 2021; 10:jcm10051098. [PMID: 33807964 PMCID: PMC7961756 DOI: 10.3390/jcm10051098] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Revised: 03/02/2021] [Accepted: 03/03/2021] [Indexed: 11/16/2022] Open
Abstract
We investigated the long-term visual and anatomical outcomes of aflibercept monotherapy for exudative age-related macular degeneration (AMD) with good baseline best-corrected visual acuity (BCVA). A medical chart review was performed for 40 consecutive patients with baseline decimal BCVA ≥ 0.6 secondary to exudative AMD. Three monthly injections were administrated, and thereafter additional injection was performed if needed over 5 years. In total, 13 eyes with neovascular AMD (nAMD) and 27 eyes with polypoidal choroidal vasculopathy (PCV) were enrolled. In both groups, the mean BCVA significantly improved at the 12-month visit (p < 0.05). However, the significant improvement in BCVA disappeared at the 24-month visit, and the final mean BCVA was equivalent to that at baseline (p = 0.17 in the nAMD group and p = 0.15 in the PCV group). The median number of injections required after the loading dose was 15.0 during the 5-year follow-up (nAMD:15.0 vs. PCV:15). During the study period, 37 (92.5%) eyes required retreatment(s). Cox regression analysis demonstrated that the protective allele of ARMS2 A69S was associated with a retreatment-free period from the initial injection (p = 0.041, repeated forward selection method). As-needed aflibercept monotherapy is a preferable treatment option for exudative AMD with good initial visual acuity regardless of nAMD or PCV during the 5-year study period.

Abstract
PURPOSE To evaluate the one-year efficacy of intravitreal aflibercept injection in polypoidal choroidal vasculopathy (PCV) with best-corrected visual acuity (BCVA) of 20 / 40 or better. METHODS This was a multicenter retrospective study. The medical records of patients diagnosed with treatment-naïve PCV were retrospectively reviewed. Patients with an initial BCVA of 20 / 40 or better and who had undergone intravitreal aflibercept injection were included. Patients were treated with three consecutive monthly injections, followed by pro re nata regimen according to the clinician's discretion at variable interval visits. The proportions of eyes for which BCVA was maintained (≤ 0.2 logarithm of the minimum angle of resolution change) or improved at 12 months were evaluated. The changes of BCVA, central subfield macular thickness (CSMT), pigment epithelial detachment, and subretinal fluid also were assessed. RESULTS A total of 86 eyes were included. The mean number of injections for 12 months of treatment was 5.4 ± 1.7. BCVA was maintained or improved in 94.2% (81 / 86) of cases. Mean BCVA (logarithm of the minimum angle of resolution) had changed from the baseline (0.23 ± 0.09) at 3 months (0.21 ± 0.14), 6 months (0.24 ± 0.22), and 12 months (0.20 ± 0.18), but with no statistical significance. CSMT had improved significantly from the baseline (336.1 ± 97.3 μm) at 3 months (223.6 ± 47.22 μm), 6 months (239.6 ± 64.2 μm), and 12 months (223.8 ± 47.9 μm). Pigment epithelial detachment was observed in 93% of cases at the baseline, 72.1% at 3 months, and 69.8% at 12 months, showing a significant decrease at all observation points. Subretinal fluid was observed in 91.9% of cases at the baseline, 20.9% at 3 months, and 29.1% at 12 months, showing a significant decrease at all observation points. CONCLUSIONS In cases of PCV with good visual acuity, intravitreal aflibercept injections decreased CSMT and were effective in maintaining visual acuity.

Abstract
The insulin-like growth factor (IGF) axis has been implicated in the progression of malignant disease and identified as a clinically important therapeutic target. Several IGF-1 receptor (IGF-1R) targeting drugs including humanized monoclonal antibodies have advanced to phase II/III clinical trials, but to date, have not progressed to clinical use, due, at least in part, to interference with insulin receptor signalling. We previously reported on the production of a soluble fusion protein consisting of the extracellular domain of human IGF-1R fused to the Fc portion of human IgG1 (first generation IGF-TRAP) that bound human IGF-1 and IGF-2 with a 3 log higher affinity than insulin. We showed that the IGF-TRAP had potent anti-cancer activity in several pre-clinical models of aggressive carcinomas. Here we report on the re-engineering of the IGF-TRAP with the aim of improving physicochemical properties and suitability for clinical applications. We show that cysteine-serine substitutions in the Fc hinge region of IGF-TRAP eliminated high-molecular-weight oligomerized species, while a further addition of a flexible linker, not only improved the pharmacokinetic profile, but also enhanced the therapeutic profile of the IGF-TRAP, as evaluated in an experimental colon carcinoma metastasis model. Dose-response profiles of the modified IGF-TRAPs correlated with their bio-availability profiles, as measured by the IGF kinase-receptor-activation (KIRA) assay, providing a novel, surrogate biomarker for drug efficacy. This study provides a compelling example of structure-based re-engineering of Fc-fusion-based biologics for better manufacturability that also significantly improved pharmacological parameters. It identifies the re-engineered IGF-TRAP as a potent anti-cancer therapeutic.

Abstract
Nonresponsiveness to age-related macular degeneration (AMD) treatments has become a growing concern in ophthalmology. Disparity among publications that have assessed pharmacogenetic (PGx) connections between AMD disease genes and treatments has delayed the implementation of PGx testing in AMD. We assessed all AMD PGx publications to identify the degree of agreement for publications within similar ethnic cohorts and worldwide, and the causes for differences in study outcomes. There are no accepted genotype–phenotype correlations, either within similar ethnic cohorts or worldwide. The diversity of measured outcomes, treatment protocols and statistical methods used may be causing this discrepancy. A universally accepted treatment protocol and the creation of agreed response group classification may bridge the gap between AMD PGx publications.
