Background/AimsTo provide longer-term data on efficacy, safety, immunogenicity and pharmacokinetics (PK) of ranibizumab biosimilar SB11 compared with the reference ranibizumab (RBZ) in patients with neovascular age-related macular degeneration (nAMD).Methods Setting: Multicentre. Design: Randomised, double-masked, parallel-group, phase III equivalence study. Patient population: ≥50 years old participants with nAMD (n=705), one ‘study eye’. Intervention: 1:1 randomisation to monthly intravitreal injection of 0.5 mg SB11 or RBZ. Main outcome measures: Visual efficacy endpoints, safety, immunogenicity and PK up to 52 weeks.ResultsBaseline and disease characteristics were comparable between treatment groups. Of 705 randomised participants (SB11: n=351; RBZ: n=354), 634 participants (89.9%; SB11: n=307; RBZ: n=327) completed the study until week 52. Previously reported equivalence in primary efficacy remained stable up to week 52 and were comparable between SB11 and RBZ. The adjusted treatment difference between SB11 and RBZ in full analysis set at week 52 of change from baseline in best-corrected visual acuity was −0.6 letters (90% CI −2.1 to 0.9) and of change from baseline in central subfield thickness was −14.9 µm (95% CI –25.3 to –4.5). The incidence of ocular treatment-emergent adverse events (TEAEs) (SB11: 32.0% vs RBZ: 29.7%) and serious ocular TEAE (SB11: 2.9% vs RBZ: 2.3%) appeared comparable between treatment groups, and no new safety concerns were observed. The PK and immunogenicity profiles were comparable, with a 4.2% and 5.5% cumulative incidence of antidrug antibodies up to week 52 for SB11 and RBZ, respectively.ConclusionsLonger-term results of this study further support the biosimilarity established between SB11 and RBZ.

PurposeTo characterize relationships between Consensus on Neovascular Age-Related Macular Degeneration Nomenclature (CONAN) Study Group classifications of macular neovascularization (MNV) and visual responses to ranibizumab in patients with neovascular age-related macular degeneration (nAMD).MethodsThis was a post hoc analysis of the phase 3 HARBOR trial of ranibizumab in nAMD. Analyses included ranibizumab-treated eyes with baseline multimodal imaging data; baseline MNV; subretinal and/or intraretinal fluid at screening, baseline, or week 1; and spectral-domain optical coherence tomography images through month 24 (n = 700). Mean best-corrected visual acuity (BCVA) over time and mean BCVA change at months 12 and 24 were compared between eyes with type 1, type 2/mixed type 1 and 2 (type 2/M), and any type 3 MNV at baseline.ResultsAt baseline, 263 (37.6%), 287 (41.0%), and 150 (21.4%) eyes had type 1, type 2/M, and any type 3 lesions, respectively. Type 1 eyes had the best mean BCVA at baseline (59.0 [95% CI: 57.7–60.3] letters) and month 24 (67.7 [65.8–69.6] letters), whereas type 2/M eyes had the worst (50.0 [48.6–51.4] letters and 60.8 [58.7–62.9] letters, respectively). Mean BCVA gains at month 24 were most pronounced for type 2/M eyes (10.8 [8.9–12.7] letters) and similar for type 1 (8.7 [6.9–10.5] letters) and any type 3 eyes (8.3 [6.3–10.3] letters).ConclusionDifferences in BCVA outcomes between CONAN lesion type subgroups support the use of an anatomic classification system to characterize MNV and prognosticate visual responses to anti-vascular endothelial growth factor therapy for nAMD.Trial registrationClinicalTrials.gov identifier: NCT00891735.

Purpose To evaluate the 1-year efficacy, durability, and safety of faricimab versus aflibercept in patients with neovascular age-related macular degeneration (nAMD) enrolled in the Japan subgroup of the TENAYA trial. Study design TENAYA (NCT03823287) was a global, phase 3, multicenter, randomized, active comparator–controlled, double-masked, noninferiority, parallel-group, 112-week trial. After completion of global enrollment, additional patients were enrolled in the Japan extension of TENAYA. Methods Treatment-naïve patients aged ≥ 50 years with nAMD were randomized (1:1) to intravitreal faricimab 6 mg up to every 16 weeks (Q16W) after 4 initial Q4W doses based on disease activity at weeks 20 and 24 or aflibercept 2 mg Q8W after 3 initial Q4W doses. Primary endpoint was mean change in best-corrected visual acuity (BCVA) from baseline averaged over weeks 40, 44, and 48. Anatomical/durability outcomes were assessed. Results Overall, 133 patients were included in the TENAYA Japan subgroup analysis (faricimab, n = 66; aflibercept, n = 67). The adjusted mean (95% confidence interval) BCVA changes were + 7.1 (4.6‒9.7) and + 7.7 (5.2‒10.1) letters in the faricimab and aflibercept treatment groups, respectively. At week 48, 66.1%, 22.6%, and 11.3% of patients in the faricimab group were on Q16W, Q12W, Q8W and dosing intervals, respectively. Ocular adverse event rates were similar between treatment groups (faricimab, n = 14 [21.2%] versus aflibercept, n = 17 [25.4%]). Conclusion The TENAYA Japan subgroup analysis showed that faricimab up to Q16W had sustained efficacy with an acceptable safety profile. These findings are consistent with the global TENAYA and LUCERNE findings.

Background This analysis evaluated aqueous humour (AH) interleukin (IL)-6 concentrations and the association between AH IL-6 and visual outcomes in patients with neovascular age-related macular degeneration (nAMD) or diabetic macular oedema (DMO) receiving anti–vascular endothelial growth factor (VEGF) monotherapy. Methods Post hoc analysis of the multicentre, double-masked, randomised HARBOR (NCT00891735) and READ-3 (NCT01077401) trials. HARBOR enrolled treatment-naïve nAMD patients. READ-3 enrolled treatment-naïve/previously treated DMO patients. HARBOR patients received ranibizumab 0.5 or 2.0 mg monthly or as needed; AH samples were collected at month 2, after two previous intravitreal injections. READ-3 patients received ranibizumab 0.5 or 2.0 mg as needed; AH samples were collected at baseline and months 3, 6, 9, and 12. Main outcome measure: association between AH IL-6 concentrations and month 24 best-corrected visual acuity (BCVA). Results In both trials (HARBOR, N  = 36; READ-3, N  = 137), patients with higher AH IL-6 concentrations had worse visual outcomes. HARBOR patients with low AH IL-6 concentrations at month 2 had a mean (95% CI) BCVA change at month 24 of +2.9 (−2.6, 8.3) letters, whereas patients with high AH concentrations had a mean (95% CI) BCVA change of −9.0 (−22.7, 4.7) letters. READ-3 patients with low AH concentrations at baseline had a mean (95% CI) BCVA change at month 12 of +9.3 (7.4, 11.3) letters, whereas patients with high AH concentrations had a mean (95% CI) BCVA change of +5.6 (2.2, 9.1) letters. Conclusions Higher IL-6 AH concentrations may predict suboptimal visual responses to anti–VEGF monotherapy in patients with nAMD/DMO.

To investigate quantitative associations between AI-assessed disease activity and optical coherence tomography angiography (OCTA)-derived parameters in patients with neovascular age-related macular degeneration (nAMD) undergoing anti-VEGF therapy. OCTA and SD-OCT images obtained from multicenter, randomized study data were evaluated. A deep learning algorithm (RetInSight) was used to detect and quantify macular fluid on SD-OCT. Mixed effects models were applied to evaluate correlations between fluid volumes, macular neovascularization (MNV)-type and OCTA-derived MNV parameters; lesion size (LS) and vessel area (NVA). 230 patients were included. A significant positive correlation was observed between SRF and NVA (estimate = 199.8 nl/mm 2 , p  = 0.023), while a non-significant but negative correlation was found between SRF and LS (estimate = − 71.3 nl/mm 2 , p  = 0.126). The presence of Type I and Type II MNV was associated with significantly less intraretinal fluid (IRF) compared to Type III MNV (estimate type I:− 52.1 nl, p  = 0.019; estimate type II:− 51.7 nl, p  = 0.021). A significant correlation was observed between pigment epithelial detachment (PED) and the interaction between NVA and LS (estimate:28.97 nl/mm 2 ; p  = 0.012). Residual IRF at week 12 significantly correlated to baseline NVA (estimate:38.1 nl/mm 2 ; p  = 0.015) and LS (estimate:− 22.6 nl/mm 2 ; p  = 0.012). Fluid in different compartments demonstrated disparate associations with MNV OCTA features. While IRF at baseline was most pronounced in type III MNV, residual IRF was driven by neovascular MNV characteristics. Greater NVA in proportion to LS was associated with higher amounts of SRF and PED. The correlation between these parameters may represent MNV maturation and can be used as a biomarker for resolution of disease activity. AI-based OCT analysis allows for a deeper understanding of neovascular disease in AMD and the potential to adjust therapeutic strategies to optimize outcomes through precision medicine.

PurposePost hoc analysis of the phase III HAWK and HARRIER studies to compare the reductions in subretinal hyper-reflective material (SHRM) thickness following brolucizumab 6 mg or aflibercept 2 mg treatment and to assess SHRM thickness and thickness variability as a potential biomarker of visual outcomes in patients with neovascular age-related macular degeneration (nAMD).MethodsOptical coherence tomography images from the brolucizumab (n=700) and aflibercept (n=696) arms were analysed for the maximum SHRM thickness across the macula over 96 weeks. In a pooled treatment-agnostic analysis, the effect of week 12 SHRM thickness and SHRM thickness variability on best-corrected visual acuity (BCVA) through week 96 were also assessed.ResultsBrolucizumab was associated with numerically higher percentage reductions from baseline in SHRM thickness versus aflibercept in all patients (week 96: 54.4% vs 47.6%, respectively) and also in the matched subgroups with disease activity at week 16 (week 96: 51.6% vs 33.8%, respectively). In eyes with lower SHRM measurements at week 12, mean BCVA gains from baseline were higher at week 96 (<200 µm, +6.47 Early Treatment Diabetic Retinopathy Study letters; ≥200 µm, +3.10 letters). Eyes with the lowest SHRM thickness variability from week 12 to week 96 showed the greatest mean BCVA gains from baseline (week 96: <12 µm, +7.42 letters; >71 µm, −2.95 letters).ConclusionsIn HAWK and HARRIER, greater reductions in maximum SHRM thickness from baseline were observed with brolucizumab compared with aflibercept. Furthermore, the data suggest that SHRM thickness postloading and SHRM thickness variability over time are biomarkers for visual outcomes in patients with nAMD.

Aims To determine the level of vascular endothelial growth factor (VEGF) in the plasma of patients with diabetic macular edema (DME) and of patients with exudative age-related macular degeneration (ARMD) before and after intravitreal injection of bevacizumab, ranibizumab or pegaptanib. Methods 30 patients with DME and 30 patients with ARMD were included in this randomized controlled study. Patients were randomized to treatment with ranibizumab (0.5 mg), bevacizumab (1.25 mg) or pegaptanib (0.3 mg). 10 patients with DME received bevacizumab, 10 ranibizumab and 10 pegaptanib. The same randomized treatment allocation applied to the 30 patients with ARMD. The concentrations of VEGF were measured by ELISA just before the injection, after 7 days and 1 month. Results Plasma VEGF in patients with exudative ARMD before the injection of bevacizumab was 89.7 pg/ml. It was significantly reduced to 25.1 pg/ml after 7 days (p=0.01), and to 22.8 pg/ml after 1 month (p=0.008). In patients with DME the same systemic reduction by bevacizumab was observed with a significant decrease of baseline VEGF level from 72.2 pg/ml to 13.7 pg/ml after 7 days (p=0.008) and 17.1 pg/ml at 4 weeks with (p=0.012). No significant reductions of plasma VEGF levels were observed in patients receiving ranibizumab or pegaptanib during follow-up. Conclusions Bevacizumab significantly reduces the level of VEGF in the blood plasma for up to one month in patients with DME as well as in those with ARMD. No significant systemic effects of intravitreal ranibizumab or pegaptanib on plasma VEGF could be observed.

Purpose To evaluate 2-year efficacy, durability, and safety of faricimab in the TENAYA Japan subgroup and pooled global TENAYA/LUCERNE cohort of patients with neovascular age-related macular degeneration (nAMD). Methods Subgroup analysis of TENAYA/LUCERNE (NCT03823287/NCT03823300): phase III, multicentre, randomised, active comparator–controlled, double-masked, non-inferiority trials. Treatment-naïve patients aged ≥ 50 years with nAMD were randomised (1:1) to intravitreal faricimab (6.0 mg up to every 16 weeks [Q16W] after 4 initial Q4W doses) or aflibercept (2.0 mg Q8W after 3 initial Q4W doses). Outcomes were assessed through year 2 for the TENAYA Japan subgroup ( N  = 133) and global pooled TENAYA/LUCERNE cohort ( N  = 1329). Results Vision and anatomic improvements achieved with faricimab at year 1 were maintained over 2 years and were generally comparable between the TENAYA Japan subgroup and pooled TENAYA/LUCERNE cohort. Adjusted mean best-corrected visual acuity (BCVA) change from baseline at year 2 for the TENAYA Japan subgroup and global pooled TENAYA/LUCERNE cohort was +7.1 (3.7–10.5) and +4.4 (3.2–5.5) letters in the faricimab arm, respectively, and +5.2 (1.9–8.6) and +4.3 (3.1–5.4) letters in the aflibercept arm, respectively. At week 112, the proportion of faricimab-treated patients on Q16W dosing was 61.0% and 63.1% in the TENAYA Japan subgroup and pooled TENAYA/LUCERNE cohort. Faricimab was well tolerated through year 2. Conclusion Year 2 TENAYA Japan subgroup findings for faricimab were generally consistent with the pooled global TENAYA/LUCERNE results in patients with nAMD. Vision and anatomical benefits with faricimab were similar to those with aflibercept but with fewer injections.

Background and Objective This was a prospective multicenter, randomized, double-masked, active-controlled study, the aim of which was to demonstrate the efficacy and safety of intravitreal ONS-5010 (bevacizumab-vikg) in eyes with neovascular age-related macular degeneration (nAMD). This was a phase III trial on ONS-5010 (NORSE TWO). Materials and Methods Treatment-naïve nAMD patients aged 50 years and older with a best-corrected distance visual acuity (BCVA) of 25 to 67 Early Treatment Diabetic Retinopathy Study (ETDRS) letters and evidence of disease activity were included. Subjects randomized to ONS-5010 received monthly intravitreal doses of 1.25 mg of ONS-5010, bevacizumab-vikg (Outlook Therapeutics) for 12 months. Subjects randomized to ranibizumab received 0.50 mg of ranibizumab on days 0, 30, 60, 150, and 240 based on the PIER study dosing regimen. Results The primary end point was the proportion of subjects who gained ≥ 15 letters from baseline in BCVA at 11 months, and evaluating the safety and tolerability of intravitreal injections of ONS-5010 administered monthly from baseline to 12 months. One hundred thirteen subjects were included in the ONS-5010 group and 115 subjects were included in the ranibizumab group. Respectively, 41.7% and 23.1% of patients gained ≥ 15 letters (3 lines) of visual acuity, with a risk difference of 0.1859 [95% CI = 0.0442, 0.3086]; P = 0.0052. The change in BCVA from baseline to 11 months was found to be 11.2 ± 12.19 and 5.8 ± 14.80 ETDRS letters, respectively. The number of subjects gaining ≥ 5 and ≥ 10 letters and subjects losing < 15 letters was significantly higher in the ONS-5010 group. Similarly, subjects with a Snellen visual acuity equivalent of 20/200 (35 ETDRS letters) or worse at 11 months were significantly fewer in the ONS-5010 group. Only one subject in the ONS-5010 group had a study-related serious ocular adverse event (SAE), namely, elevated intraocular pressure. The most common adverse event in the ONS-5010 group was conjunctival hemorrhage (8.8%), and reduced visual acuity in the ranibizumab group (12.2%). Conclusions In the prescribed treatment plan, ONS-5010 exhibited strong effectiveness in improving or stabilizing visual acuity and was also well tolerated. Bevacizumab and ranibizumab displayed a comparable safety profile. [Ophthalmic Surg Lasers Imaging Retina 2024;55:XX–XX.]

ObjectivesTo assess the therapeutic response to brolucizumab and aflibercept by deep learning/OCT-based analysis of macular fluid volumes in neovascular age-related macular degeneration.MethodsIn this post-hoc analysis of two phase III, randomised, multi-centre studies (HAWK/HARRIER), 1078 and 739 treatment-naive eyes receiving brolucizumab or aflibercept according to protocol-specified criteria in HAWK and HARRIER, respectively, were included. Macular fluid on 41,840 OCT scans was localised and quantified using a validated deep learning-based algorithm. Volumes of intraretinal fluid (IRF), subretinal fluid (SRF), pigment epithelial detachment (PED) for all central macular areas (1, 3 and 6 mm) in nanolitres (nL) and best corrected visual acuity (BCVA) change in ETDRS letters were associated using mixed models for repeated measures.ResultsBaseline IRF volumes decreased by >92% following the first intravitreal injection and consistently remained low during follow-up. Baseline SRF volumes decreased by >74% following the first injection, while PED volume resolved by 68–79% of its baseline volume. Resolution of SRF and PED was dependent on the substance and regimen used. Larger residual post-loading IRF, SRF and PED volumes were all independently associated with progressive vision loss during maintenance, where the differences in mean BCVA change between high and low fluid volume subgroups for IRF, SRF and PED were 3.4 letters (p < 0.0001), 1.7 letters (p < 0.001) and 2.5 letters (p < 0.0001), respectively.ConclusionsDeep-learning methods allow an accurate assessment of substance and regimen efficacy. Irrespectively, all fluid compartments were found to be important markers of disease activity and were relevant for visual outcomes.
