Intravitreal anti-vascular endothelial growth factor and combined photodynamic therapy for pachychoroid neovasculopathy: long-term treatment outcomes. Graefes Arch Clin Exp Ophthalmol 2024; 262:1811-1818. [PMID: 38294513 PMCID: PMC11106190 DOI: 10.1007/s00417-024-06387-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Revised: 12/23/2023] [Accepted: 01/20/2024] [Indexed: 02/01/2024] Open
Abstract
PURPOSE To examine the long-term visual outcomes after initial treatment with combined photodynamic therapy (PDT) or aflibercept treat-and-extend (TAE) monotherapy in patients with pachychoroid neovasculopathy (PNV). METHODS Patients diagnosed with PNV, initially treated with PDT combined with anti-vascular endothelial growth factor (VEGF) or intravitreal aflibercept (IVA) monotherapy in the TAE protocol and followed up for at least 6 months, were included in the study. Medical records were retrospectively reviewed. Survival analysis was performed, in which deterioration in logMAR visual acuity by 0.1 or 0.3 is defined as "death." The annual number of treatments was also analyzed. Sub-analysis was performed on 33 patients diagnosed with PNV without polypoidal lesions. RESULTS This study included 46 patients (23 in the initial combined PDT group and 23 in the IVA TAE group). Mean age, sex, mean baseline logMAR visual acuity, or duration of observation (3.6 ± 3.2 years vs. 3.1 ± 1.9 years) in both groups were comparable. As for visual outcome, no significant differences were found in survival analysis based on worsening of 0.1 or 0.3 logMAR (3-year survival; 26% vs. 26%, 91% vs. 90%, respectively). Meanwhile, the additional number of anti-VEGF injections per year was significantly lower in the initial combined PDT group than in the IVA TAE group (1.0 ± 1.3 vs. 4.1 ± 1.5, p < 0.0001). No significant differences were found in the number of additional PDTs per year (0.07 ± 0.20 vs. 0.02 ± 0.09, p = 0.27). Similar results were found in a sub-analysis of 33 patients without polyps. CONCLUSION In the treatment of PNV, regardless of the presence of polyps, the long-term visual outcomes were similar between the initial combined PDT and IVA TAE monotherapy. However, the annual number of anti-VEGF injections was lower in the initial combined PDT group than in the aflibercept TAE group, whereas that of PDT was comparable.

Intravitreal Aflibercept for Neovascular Age-Related Macular Degeneration Beyond One Year of Treatment: AZURE, a Randomized Trial of Treat-and-Extend vs. Fixed Dosing. Adv Ther 2024; 41:1010-1024. [PMID: 38183525 PMCID: PMC10879225 DOI: 10.1007/s12325-023-02719-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Accepted: 10/23/2023] [Indexed: 01/08/2024]
Abstract
INTRODUCTION AZURE was a 76-week, randomized, open-label, parallel-group, phase IIIb noninferiority study comparing the efficacy and safety of intravitreal aflibercept (IVT-AFL) in a treat-and-extend (T&E) regimen with fixed dosing in patients with neovascular age-related macular degeneration (nAMD) previously receiving IVT-AFL for ≥ 1 year. METHODS Patients were aged ≥ 51 years and had completed ≥ 1 year of IVT-AFL treatment prior to enrollment (IVT-AFL once per month [- 1 or + 2 weeks] for 3 months followed by IVT-AFL every 2 months [6-12 weeks]). Patients were randomly assigned (1:1) to receive IVT-AFL 2 mg in either a T&E (minimum treatment interval of 8 weeks with no upper limit, adjusted according to functional and anatomic outcomes, as assessed by the investigator; n = 168), or a fixed dosing regimen (treatment every 8 weeks [± 3 days]; n = 168). The primary endpoint was best-corrected visual acuity (BCVA) change from baseline to week (W) 52. The key secondary endpoint was the proportion of patients maintaining vision (< 15-letter loss) at W52. RESULTS The full analysis set comprised 332 patients (T&E: n = 165; fixed dosing: n = 167). Mean BCVA change (baseline to W52) was - 0.3 ± 7.5 vs. - 0.5 ± 8.4 letters (T&E vs. fixed dosing; least-squares mean difference [95% CI]: 0.22 [- 1.51 to 1.96] letters; P < 0.0001 for noninferiority test [5-letter margin]). From baseline to W52, 95.2% (T&E) and 94.0% (fixed dosing) of patients maintained vision. Mean central subfield thickness change from baseline to W52 was - 24 ± 55 (T&E) and - 33 ± 47 (fixed dosing) µm. Last treatment interval to W76 was ≥ 12 weeks for 37.0% of T&E patients. No new safety signals were identified. CONCLUSION IVT-AFL T&E can achieve similar functional and anatomic outcomes to fixed dosing every 8 weeks over 52 weeks in patients with nAMD who have completed ≥ 1 year of treatment, while reducing treatment burden.

[PMID: 37924481 PMCID: PMC10776559 DOI: 10.1007/s40123-023-00830-w] [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: 05/31/2023] [Accepted: 09/29/2023] [Indexed: 11/06/2023] Open
Abstract
INTRODUCTION AURIGA is the largest real-world study to date to evaluate intravitreal aflibercept (IVT-AFL) treatment of diabetic macular edema or macular edema secondary to retinal vein occlusion (RVO) in routine clinical practice. Here, we report the 24-month outcomes in the RVO cohort from France, Germany, Italy, and Taiwan. METHODS AURIGA (NCT03161912) was a prospective observational study. Eligible patients with RVO were enrolled for whom the decision to treat with IVT-AFL had already been made by the attending physician. Patients were treated with IVT-AFL for up to 24 months at physician discretion according to local practice. The primary endpoint was mean change in visual acuity (VA; Early Treatment Diabetic Retinopathy Study [ETDRS] letters) from baseline to month (M) 12. All statistical analyses were descriptive. RESULTS In 554 treatment-naïve and 65 previously treated patients with RVO, the respective mean (95% confidence interval) change in VA from baseline was + 12.5 (10.8, 14.3) and + 7.9 (3.3, 12.6) letters by M12 and + 11.4 (9.4, 13.3) and + 4.4 (- 0.6, 9.5) letters by M24 (baseline mean ± standard deviation: 51.0 ± 21.9 and 51.9 ± 20.4 letters); 44.0% of treatment-naïve and 27.9% of previously treated patients reported ≥ 15-letter gains by M24. By M24, the mean change in central retinal thickness from baseline was - 247 (- 267, - 227) µm in treatment-naïve patients and - 147 (- 192, - 102) µm in previously treated patients. From baseline to M6, M12, and M24, treatment-naïve patients received a total of 4.0 ± 1.3, 5.5 ± 2.5, and 6.9 ± 4.2 injections, respectively, and previously treated patients received 3.8 ± 1.5, 5.0 ± 2.2, and 6.3 ± 3.7 injections, respectively. The safety profile of IVT-AFL was consistent with that of previous studies. CONCLUSIONS In AURIGA, patients with RVO experienced clinically relevant functional and anatomic improvements following IVT-AFL treatment in routine clinical practice. These improvements were largely maintained in treatment-naïve patients over the 24-month study despite the decreasing treatment frequency, suggesting long-term durability of IVT-AFL treatment outcomes.

Abstract
INTRODUCTION AURIGA is the largest real-world study to date to evaluate intravitreal aflibercept (IVT-AFL) in the treatment of diabetic macular edema (DME) or macular edema secondary to retinal vein occlusion in routine clinical practice. The 24-month outcomes in the DME cohort from across 11 participating countries are reported here. METHODS AURIGA (NCT03161912) was a prospective observational study. The study enrolled eligible patients with DME for whom the decision to treat with IVT-AFL had previously been made by the attending physician. Patients were treated with IVT-AFL for up to 24 months at physician discretion according to local practice. The primary endpoint was mean change in visual acuity (VA; Early Treatment Diabetic Retinopathy Study [ETDRS] letters) from baseline to month 12 (M12). All statistical analyses were descriptive. RESULTS In 1478 treatment-naïve and 384 previously treated patients with DME, the mean (95% confidence interval) change in VA from baseline was +6.7 (5.7, 7.6) and +7.4 (5.5, 9.4) letters by M12 and +5.9 (4.9, 6.9) and +8.1 (6.1, 10.1) letters by M24 (baseline [mean ± standard deviation]: 56.0 ± 19.8 and 50.8 ± 19.5 letters), respectively; 25.9% of treatment-naïve and 32.8% of previously treated patients achieved ≥ 15-letter gains by M24. The mean change in central retinal thickness from baseline to M24 was -110 (-119, -102) µm in treatment-naïve patients and -169 (-188, -151) µm in previously treated patients. By M6, M12, and M24, treatment-naïve patients had received 3.8 ± 1.7, 4.9 ± 2.8, and 5.7 ± 3.9 injections, respectively, and previously treated patients had received 3.9 ± 1.5, 4.9 ± 2.4, and 6.2 ± 3.6 injections, respectively. The safety profile of IVT-AFL was consistent with previous studies. CONCLUSION In AURIGA, treatment-naïve and previously treated patients with DME achieved clinically relevant functional and anatomic improvements following IVT-AFL treatment for up to 24 months in routine clinical practice. Even with the decreasing injection frequency observed, these gains were largely maintained throughout the study, suggesting long-term durability of the positive effects of IVT-AFL treatment.

[PMID: 36987548 DOI: 10.1080/08820538.2023.2194983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 03/08/2023] [Accepted: 03/13/2023] [Indexed: 03/30/2023]
Abstract
INTRODUCTION There are few reports evaluating the treatment of pachychoroid neovasculopathy (PNV) in white patients. The purpose of this study is to analyze the results of a treat and extend regimen with aflibercept in white patients with PNV after 2 years of follow-up. METHODS We performed a retrospective study in 31 eyes of 26 patients with PNV treated with a treat an extend regimen of intravitreal aflibercept. The mean age was 63,84 ± 7.92 years. There were 9 males (35%) and 17 females (65%). Best-corrected visual acuity (BCVA), central macular thickness (CMT), choroidal subfoveal thickness (CST), choroidal thickness (CT) under type 1 choroidal neovascularization (CNV), pigment epithelium detachment (PED) height, and presence of subretinal fluid (SRF), intraretinal fluid (IRF) and wet macula, were evaluated at baseline and after 3, 6, 12, and 24 months. RESULTS BCVA remained stable during the follow-up (p 0.161). A significant diminution of CMT was found (p 0.001). Conversely, PED height diminution was not significative (p 0.260). CST and CT under type 1 CNV improved significantly during the follow-up (p 0.005 and 0.009, respectively). Also, wet macula improved after 24 months (p < .001). The average number of intravitreal injections was 12.34 ± 6.01. CONCLUSION Treat and extend regimen with intravitreal aflibercept in white patients with PNV may be effective for improving CMT, CST, CT under type 1 CNV and wet macula, and to stabilize vision, with a personalized regimen of intravitreal injections.

A customized regimen of intravitreal aflibercept for the treatment of choroidal neovascularization secondary to different chorioretinal diseases. Int J Retina Vitreous 2023; 9:2. [PMID: 36653854 PMCID: PMC9847200 DOI: 10.1186/s40942-023-00440-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Accepted: 12/31/2022] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND To assess the response of CNV secondary to chorioretinal diseases to IVA and to explore the adequate dosing regimen and the long-term results. METHODS A retrospective study including patients with treatment-naïve active CNV secondary to chorioretinal diseases. All patients received an initial IVA injection followed by a PRN regimen. The main outcome measures were improvement of BCVA, improvement of anatomical morphology and vascularity of the CNV on SS-OCT, and SS-OCTA, respectively, and ocular or systemic complications attributed to IVA. RESULTS The study included 17 eyes of 15 patients. Nine patients (60%) were females. The median age was 20 years. The main primary chorioretinal disease was vitelliform macular dystrophy (29%). The mean baseline BCVA was 0.16. The mean follow-up period was 15 months. Final BCVA improved by a mean of 6 lines. The CNV regressed or became inactive in all eyes. The median number of IVA injections was 2. There were no ocular or systemic complications attributed to IVA. CONCLUSION The customized IVA regimen is effective in inducing long-term regression of secondary CNV and in improving BCVA. Multimodal imaging is fundamental in establishing the diagnosis of CNV, and in monitoring its response to IVA.

Patients with Neovascular Age-Related Macular Degeneration Requiring Intensive Intravitreal Aflibercept Treatment: An ARIES Post Hoc Analysis. Ophthalmol Ther 2022; 11:1793-1803. [PMID: 35821380 PMCID: PMC9437180 DOI: 10.1007/s40123-022-00541-8] [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: 05/04/2022] [Accepted: 06/14/2022] [Indexed: 11/27/2022] Open
Abstract
INTRODUCTION The aim of this post hoc analysis of the ARIES study is to explore the requirement for intravitreal aflibercept (IVT-AFL) treatment intervals of < 8 weeks (w) in patients with neovascular age-related macular degeneration (nAMD), and to assess vision and anatomic outcomes in such patients who require more intensive treatment. METHODS ARIES was a multicenter, randomized, phase 3b/4 study that investigated the efficacy of two IVT-AFL proactive, individualized, treat-and-extend regimens over 2 years in treatment-naïve patients with nAMD. Patients were determined as injection-intensive if the study investigator identified that a treatment interval of < 8 w was needed and if they had ≥ 1 interval of < 8 w after three initial monthly doses. Treatment intervals could be extended subsequently if extension criteria were met. This is a post hoc analysis of patients enrolled in ARIES and statistical analysis is descriptive. RESULTS Of 269 patients in the combined treatment arms, 23.0% (n = 62) were injection-intensive (Year 1: 13.8% [n = 37]; Year 2: 9.3% [n = 25]). Time from IVT-AFL initiation to injection-intensive determination varied (range, 16-100 w; median: 43.2 w). Mean treatment interval was 8.4 w before and 6.1 w after injection-intensive determination. Overall, 59.7% achieved treatment intervals of ≥ 8 w following injection-intensive determination. Vision improvements from baseline to Week 104 were smaller for injection-intensive patients than non-injection-intensive patients (mean [SD] best-corrected visual acuity change: + 2.3 [15.6] vs. + 5.9 [12.3] letters). Anatomic outcomes were similar between injection-intensive and non-injection-intensive patients (central retinal thickness change from baseline to Week 104: - 160 [154] vs. - 167 [136] µm). CONCLUSIONS In ARIES, 23% of treatment-naïve patients with nAMD experienced at least one treatment interval of < 8 w. Injection-intensive patients showed improved vision and anatomic outcomes. For most, treatment intervals could be extended to ≥ 8 w following injection-intensive determination. CLINICALTRIALS gov Identifier: NCT02581891.

Abstract
Purpose To report the safety and effectiveness of intravitreal aflibercept (IVT-AFL) for diabetic macular edema (DME) in the real-world clinical practice setting in Japan. Methods In this prospective, multicenter, observational, post-marketing surveillance, patients with DME newly receiving IVT-AFL were enrolled. During a 24-month follow-up, the primary outcome was the occurrence of safety events. Other pre-specified endpoints were effectiveness indicators, such as best-corrected visual acuity (BCVA), central retinal thickness, and injection frequency. Results In total, 646 patients administered at least one IVT-AFL injection were included in the safety analysis. During the follow-up period, adverse events occurred in 42 patients (6.50%), whereas adverse drug reactions occurred in 12 (1.86%). In the 12 patients who had adverse drug reactions, seven events occurred in seven patients within the first month of the most recent injection. In addition, 622 patients were included in the effectiveness analysis set. The number of injections over 24 months was 3.6 ± 3.0 (mean ± standard deviation [SD]). BCVA (logarithm of the minimum angle of resolution) was 0.437 ± 0.362 (mean ± SD) (n = 622) at baseline and 0.321 ± 0.348 (n = 177) after 24 months of treatment with IVT-AFL. Central retinal thickness was 440.8 ± 134.2 μm (mean ± SD) (n = 444) at baseline and 355.5 ± 126.4 μm (n = 140) at 24 months. Conclusion Routine administration of IVT-AFL for DME was not associated with new safety concerns, and BCVA outcomes were maintained over 24 months in the real-world setting. Nonetheless, patients in this real-world setting received fewer injections than those in clinical trials, suggesting that a margin for improvement exists in clinical practice.

Abstract
Introduction To explore the efficacy and safety of intravitreal aflibercept (IVT-AFL) proactive, individualized treat-and-extend (T&E) regimens in exudative age-related macular degeneration (AMD) in the subgroup of patients with polypoidal choroidal vasculopathy (PCV) enrolled in the ALTAIR study. Methods This was a PCV subgroup analysis of ALTAIR, a 96-week, randomized, open-label, phase 4 study in treatment-naïve patients with exudative AMD in Japan. Following three initial monthly doses, patients received IVT-AFL at week 16 and were randomized 1:1 to T&E regimens with either 2-week (IVT-AFL-2W) or 4-week (IVT-AFL-4W) adjustments. The primary endpoint of ALTAIR was the mean change in best-corrected visual acuity (BCVA) from baseline to week 52. Endpoints were assessed at weeks 52 and 96. Safety analyses were conducted. Results A total of 90 patients with PCV were included within the full analysis set. From baseline to week 52, mean [standard deviation (SD)] change in BCVA was + 7.5 (14.7) letters and + 8.2 (11.6) letters in the IVT-AFL-2W and IVT-AFL-4W groups, respectively. From baseline to week 96, 91.3% and 90.9% of patients maintained vision in the IVT-AFL-2W and IVT-AFL-4W groups, respectively. From baseline to week 52, mean (SD) change in central retinal thickness was − 153 (177) µm and −112 (122) µm in the IVT-AFL-2W and IVT-AFL-4W groups, respectively. Overall, 51.1% of patients (IVT-AFL-2W, 43.5%; IVT-AFL-4W, 59.1%) achieved a treatment interval of 16 weeks between weeks 16 and 96. The safety profile of IVT-AFL was consistent with previous studies. Conclusion In treatment-naïve patients with PCV, IVT-AFL administered using two different T&E regimens improved and maintained functional and anatomic outcomes over 96 weeks while minimizing treatment burden.

Multimodal imaging of unusual macular macroaneurysm rupture after navigated retinal laser in a patient with adult onset Coats disease. Am J Ophthalmol Case Rep 2022; 26:101458. [PMID: 35282602 PMCID: PMC8914334 DOI: 10.1016/j.ajoc.2022.101458] [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: 08/17/2021] [Revised: 02/14/2022] [Accepted: 02/24/2022] [Indexed: 11/27/2022] Open
Abstract
Purpose To report the uncommon rupture of a macular macroaneurysm (MAR) during navigated retinal laser (Navilas®) focal treatment in a patient with adult onset Coats disease. Observation A 30-year-old man consulted for progressive decrease of vision in his right eye from one week. Fundoscopy examination showed macular hard exudates, aneurysms, vascular telangiectasias in the temporal inferior quadrant consistent with an adult onset Coats disease (CD). Spectral domain optical coherence tomography (SD-OCT) and fluorescein angiography (FA) revealed macular edema, vessels abnormalities associate to non-perfused areas. Ultra-widefield optical coherence tomography angiography (UWF-OCTA) clearly showed the blood flow abnormalities in both superficial and deep capillary plexus. Focal laser photocoagulation of abnormal vessels by navigated retinal laser and intravitreal injections (IVT) of aflibercept, successfully resolved macular edema. During supplemental navigated focal laser treatment, a macular macroaneurysm rupture occurred, causing intravitreal hemorrhage with a self-limiting resolution in three months. Indeed, visual acuity progressively improved during follow-up and absence of macular edema was observed at 18 months. Conclusion Adult onset CD is a rare condition. Our patient presented an unusual intravitreal hemorrhagic complication due to a MAR rupture after focal navigated laser treatment. Despite this complication, early laser photocoagulation and IVT injections of anti-VEGF, successfully resolved macular edema. UWF-OCTA follow-up clearly showed abnormal vessels in both superficial capillary plexus (SCP) and deep capillary plexus (DCP) and successfully guided additional navigated focal laser treatment.

2-Year Real-World Outcomes with Intravitreal Aflibercept in Neovascular Age-Related Macular Degeneration: Literature Review and Meta-analysis of Patient-Relevant Outcomes. Ophthalmol Ther 2021; 10:397-411. [PMID: 34075564 PMCID: PMC8319257 DOI: 10.1007/s40123-021-00350-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Accepted: 04/30/2021] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND The 96 weeks' assessment from the VIEW studies provided insights into the long-term efficacy of intravitreal aflibercept (IVT-AFL) in neovascular age-related macular degeneration (nAMD) and demonstrated that it was possible to maintain long-term outcomes while moving from a fixed bimonthly regimen in Year 1 to a variable dosing regimen in Year 2. The aim of this analysis was to perform a literature review and meta-analysis assessing the use of IVT-AFL and real-world outcomes in treatment-naïve patients with nAMD treated with IVT-AFL for 2 years, as per label. METHODS A literature review and meta-analysis were performed to provide an overview of the baseline characteristics of the population, the 2-year outcomes, the associated treatment burden, and safety. RESULTS Eleven publications providing data from patients with nAMD who had treatment initiated with IVT-AFL between 2012 and 2016 were identified. The mean baseline age of patients was 78.62 years, with a baseline best-corrected visual acuity (BCVA) of 57.73 Early Treatment Diabetic Retinopathy Study (ETDRS) letters. Patients reported a mean BCVA at 2 years of 62.55 ETDRS letters, with 47.39% of patients having a BCVA ≥ 70 ETDRS letters. Mean gain in BCVA versus baseline was + 4.49 ETDRS letters for the combined population (+ 5.91 letters for patients treated with a treat-and-extend regimen). Over the 2 years of the study, patients received an average of 12.34 injections, with a reduction in injections in Year 2 versus Year 1. The qualitative assessment of the safety data suggested that no new safety signals were identified. CONCLUSION Patients treated with IVT-AFL reported significant gains in visual acuity versus baseline after 2 years. The evidence identified indicates that the visual gains achieved during the first year of treatment are maintained through the second year and that these were achieved with a reduction in the mean number of IVT-AFL injections administered in Year 2 of treatment.

Intravitreal Aflibercept in Japanese Patients with Neovascular Glaucoma: The VEGA Randomized Clinical Trial. Adv Ther 2021; 38:1116-1129. [PMID: 33330958 PMCID: PMC7889669 DOI: 10.1007/s12325-020-01579-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 11/19/2020] [Indexed: 11/30/2022]
Abstract
Introduction Neovascular glaucoma is characterized by neovascularization of the iris and the anterior angle chamber. Intravitreal anti-vascular endothelial growth factor agents may improve intraocular pressure (IOP) and neovascularization. Methods The VEGA trial assessed the efficacy and safety of intravitreal aflibercept (IVT-AFL) in patients with neovascular glaucoma in a 13-week, randomized, double-masked, sham-controlled, phase 3 study performed at multiple sites in Japan that enrolled patients with anterior segment neovascularization and IOP > 25 mmHg. Patients received background therapy plus IVT-AFL (2 mg) or sham injection at baseline. Patients were re-treated if presenting with IOP > 21 mmHg and incomplete regression of iris neovascularization, receiving additional sham or IVT-AFL injections at week 1 and IVT-AFL injections at weeks 5 and/or 9. Double-masking was maintained throughout. The primary endpoint was change in IOP from baseline to week 1. Results Fifty-four patients were randomly assigned (full analysis set); the per-protocol set comprised 52 patients. At week 1, the least squares mean change in IOP was −9.9 mmHg for IVT-AFL versus −5.0 mmHg for sham [full analysis set: difference −4.9 mmHg (95% confidence interval −10.2 to 0.3; P = 0.06); per-protocol set: −5.5 mmHg (95% CI −10.8 to −0.2; P = 0.04)]. At week 1, a greater proportion of patients administered IVT-AFL versus sham achieved IOP ≤ 21 mmHg and had improved neovascularization grades. Patients in the sham group who met re-treatment criteria and received IVT-AFL at week 1 [n = 22 (81.5%)] had an additional mean IOP decrease of 9.2 mmHg by week 2, and the proportion with improvement in neovascularization grades increased from 11.5% to 69.2%. Increases in the proportion of patients with improved neovascularization grades and the proportion who achieved IOP control (≤ 21 mmHg) were also observed by week 2 in this group. Overall, 77.8% and 74.1% of patients treated with IVT-AFL and sham/IVT-AFL, respectively, received a single IVT-AFL injection. The most common ocular treatment-emergent adverse event was punctate keratitis (9.3%: 7.4% and 11.1% in the IVT-AFL and sham/IVT-AFL groups, respectively). Conclusions IVT-AFL was associated with clinically meaningful improvements in IOP control, indicating that IVT-AFL may be a potential treatment option for patients with neovascular glaucoma.

Efficacy and Safety of Intravitreal Aflibercept Injection in Japanese Patients with Neovascular Glaucoma: Outcomes from the VENERA Study. Adv Ther 2021; 38:1106-1115. [PMID: 33330959 PMCID: PMC7889553 DOI: 10.1007/s12325-020-01580-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2020] [Accepted: 11/19/2020] [Indexed: 11/10/2022]
Abstract
Introduction Neovascular glaucoma is characterized by neovascularization of the iris and anterior angle chamber. Intravitreal anti-vascular endothelial growth factor agents may decrease intraocular pressure (IOP) and improve neovascularization. The VENERA study assessed the efficacy and safety of intravitreal aflibercept (IVT-AFL) in patients with neovascular glaucoma. Methods This was a 5-week, single-arm, nonrandomized, open-label, phase 3 study performed at 7 study sites in Japan that enrolled Japanese patients with anterior segment neovascularization and IOP > 25 mmHg who had not undergone (within 30 days prior), nor were imminently scheduled to undergo (within 8 days following) intraocular surgeries, including panretinal photocoagulation (PRP). Patients received background therapy plus 2 mg IVT-AFL at baseline. Background therapy with systemic IOP-lowering drugs was prohibited for 3 days before day 1 and until IOP evaluation at week 1. The primary endpoint was the change in IOP from baseline to week 1 and the secondary endpoint was the proportion of patients with an improvement of ≥ 1 grade of neovascularization of the angle (NVA) from baseline to week 1. Results Sixteen patients received treatment (full analysis set); the per-protocol set comprised 15 patients. The mean IOP decreased from 34.1 mmHg at baseline to 25.8 mmHg at week 1 (mean change, −8.3 mmHg [95% confidence interval; CI −12.2 to −4.4; P = 0.0004]). At week 1, 81.3% of patients had an improvement in the grade of neovascularization of the iris (NVI) and 50.0% of patients had an improvement in NVA grade. The proportion of patients with controlled IOP (≤ 21 mmHg) was 43.8% (95% CI 19.8–70.1) at week 1, and increased to 56.3% at week 2 and 86.7% at week 5. The most common ocular treatment-emergent adverse event was eye pain, which occurred in 4 patients (25.0%). Conclusions IVT-AFL was associated with statistically significant and clinically meaningful IOP reductions, without concomitant use of systemic IOP-lowering drugs or PRP. The safety profile was consistent with the known safety profile of IVT-AFL. These findings supplement those from the previous VEGA study, and suggest that IVT-AFL may be a potential treatment option for patients with neovascular glaucoma.

Importance of continuous treatment with intravitreal aflibercept injections in patients with neovascular age-related macular degeneration-12-month post hoc analysis of the PERSEUS real-world evidence study. Graefes Arch Clin Exp Ophthalmol 2020; 259:601-611. [PMID: 32789651 PMCID: PMC7904558 DOI: 10.1007/s00417-020-04803-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Revised: 04/29/2020] [Accepted: 06/13/2020] [Indexed: 11/25/2022] Open
Abstract
PURPOSE To investigate the influence of treatment regularity with intravitreal aflibercept injections (IVT-AFL injections) on visual acuity (VA) outcomes in patients with neovascular age-related macular degeneration (nAMD) enrolled in the PERSEUS trial who received at least 7 IVT-AFL injections during the first year. METHODS This was a post hoc analysis of the PERSEUS trial, a prospective, non-interventional, multicenter cohort study, and included 370 patients with nAMD who had received ≥ 7 IVT-AFL injections during year 1. In addition to the prespecified subgroups of treatment-naïve and previously treated patients, results were compared between patients with regular (n = 209) and irregular (n = 161) treatment. Regular treatment was defined as initial dosing with monthly IVT-AFL injections for 3 months, then bimonthly IVT-AFL injections until month 12. Irregular treatment was defined as any deviation from regular treatment (provided ≥ 7 injections were received). The outcome of primary interest was the mean change in VA from baseline after 12 months. Further outcomes of interest included VA gain or loss, proportion of patients achieving reading vision, and percentage of patients with fluid. RESULTS At month 12, the mean (± standard deviation, SD) VA improvement from baseline was 6.1 ± 15.6 Early Treatment Diabetic Retinopathy Study letters in the regular cohort and 2.5 ± 16.7 letters in the irregular cohort with ≥ 7 IVT-AFL injections (P = 0.0514). Best results were obtained in the treatment-naïve regular sub-cohort with a mean ± SD VA improvement of 8.0 ± 17.7 letters, whereas treatment-naïve patients with irregular treatment experienced a considerably lower VA gain (2.8 ± 20.0 letters). Irregular treatment consistently correlated with inferior results in treatment-naïve patients. At month 12, the proportion of treatment-naïve patients who had experienced a worsening of ≥ 5 letters was 29.6% in the irregular sub-cohort versus 13.6% in the regular sub-cohort (P = 0.0049). However, among the treatment-naïve patients, the mean number of injections was significantly higher in the irregular than in the regular sub-cohort (8.0 ± 1.2 vs. 7.4 ± 0.6; P = 0.0001). Furthermore, compared with the treatment-naïve, regular sub-cohort, patients in the irregular sub-cohort had more visits (19.1 ± 8.6 vs. 16.1 ± 5.7), VA tests (14.2 ± 6.9 vs. 12.0 ± 4.6), and optical coherence tomography examinations (5.1 ± 3.7 vs. 3.4.0 ± 3.0). CONCLUSIONS Although irregularly treated patients received more injections and more monitoring visits during the first year of IVT-AFL treatment, they experienced worse VA outcomes than regularly treated patients.

Impact of intravitreal aflibercept dosing regimens in treatment-naïve patients with neovascular age-related macular degeneration: 2-year results of RAINBOW. BMC Ophthalmol 2020; 20:206. [PMID: 32450838 PMCID: PMC7249443 DOI: 10.1186/s12886-020-01468-z] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Accepted: 05/08/2020] [Indexed: 11/30/2022] Open
Abstract
Background To review treatment outcomes from real-world data of patients with neovascular age-related macular degeneration (nAMD) treated with intravitreal aflibercept (IVT-AFL) injection. Methods RAINBOW (ClinicalTrials.gov, NCT02279537) is an ongoing, observational, 4-year study to monitor the effectiveness and safety of IVT-AFL in patients with nAMD in clinical practice in France. Treatment-naïve patients diagnosed with nAMD who had been prescribed IVT-AFL by their treating physician were eligible. The regimens of interest were regular treatment interval cohort (patients who received three initial monthly IVT-AFL injections followed by regular injections every 2 months) and two irregular treatment interval cohorts (with and without three initial monthly injections). Here we describe results at 24 months in patients according to IVT-AFL treatment regimen. Results The mean change in best-corrected visual acuity (BCVA) with IVT-AFL from baseline to 24 months was + 3.0 letters in the overall population (P < 0.05 vs baseline). The mean change was positive for the regular and irregular treatment interval cohorts with initial doses (+ 4.9 and + 4.0 letters, respectively; P < 0.05 vs baseline) and negative for the irregular treatment interval cohort without initial doses (− 2.5 letters; P = 0.365 vs baseline) at 24 months. The mean overall number of IVT-AFL injections over 12 and 24 months was 6.0 and 8.8, respectively. The most common ocular adverse events were lack of efficacy (6.3%), vitreous floaters (2.7%), and increased lacrimation (1.7%). Conclusions In the real-world RAINBOW study, visual outcomes observed at 24 months were consistent with results from the primary endpoint at 12 months. In this study, treatment-naïve patients who received three initial IVT-AFL doses and regular IVT-AFL treatment over the first 24 months experienced better visual outcomes than patients who received no initial doses and an irregular treatment regimen.

Vision-related quality of life in Japanese patients with wet age-related macular degeneration treated with intravitreal aflibercept in a real-world setting. Jpn J Ophthalmol 2019; 63:437-447. [PMID: 31673841 DOI: 10.1007/s10384-019-00687-2] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2018] [Accepted: 07/16/2019] [Indexed: 10/25/2022]
Abstract
PURPOSE To evaluate vision-related quality of life (QoL) in wet age-related macular degeneration (wAMD) patients receiving intravitreal aflibercept (IVT-AFL). STUDY DESIGN Prospective, observational Japanese postmarketing surveillance study. METHODS All decisions were made by the treating physician. QoL was assessed using the 25-item National Eye Institute-Visual Functioning Questionnaire (NEI-VFQ-25) composite score administered at baseline, 6 months, and 12 months (primary assessment). Secondary assessments included NEI-VFQ-25 subscale scores, resource use, and best-corrected visual acuity (BCVA; logarithm of the minimum angle of resolution [logMAR]). RESULTS In total, 576 patients (baseline), 555 patients (6 months), and 446 patients (12 months) were included. The mean (SD) number of IVT-AFL injections was 3.5 (1.2) at 6 months and 4.6 (2.2) at 12 months. The mean (SD) improvement from baseline in the NEI-VFQ-25 composite score was 3.1 (11.1) at 6 months and 2.7 (12.3) at 12 months (P < .0001). For the NEI-VFQ-25 subscale scores, the mean change was ≥ 4 (minimally important difference) for general vision, near vision, and mental health at 6 months, and for general vision and mental health at 12 months (all P < .0001). A significant improvement from baseline was found in mean BCVA (logMAR) at 6 months (-0.1) and 12 months (-0.1) (P < .0001). The mean change from baseline in the NEI-VFQ-25 scores was greatest in patients with improved BCVA (gain of ≤ -0.3 logMAR units or ≥ 15 letters) after treatment. CONCLUSION IVT-AFL was associated with significant improvements in QoL and visual acuity in Japanese patients with wAMD in a real-world setting.

Intravitreal aflibercept for the treatment of radiation-induced macular edema after ruthenium 106 plaque radiotherapy for choroidal melanoma. Graefes Arch Clin Exp Ophthalmol 2019; 257:1547-1554. [PMID: 31081526 DOI: 10.1007/s00417-019-04347-6] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2018] [Revised: 04/08/2019] [Accepted: 05/01/2019] [Indexed: 12/21/2022] Open
Abstract
PURPOSE To assess the efficacy of intravitreal aflibercept in patients suffering from post-radiation macular edema following plaque radiotherapy for choroidal melanoma. METHODS This prospective, interventional case series included patients affected by radiation maculopathy (RM) with macular edema secondary to ruthenium-106 plaque brachytherapy for choroidal melanoma. The effect of intravitreal aflibercept on best-corrected visual acuity (BCVA), central foveal thickness (CFT) detected by spectral domain optical coherence tomography (sd-OCT), and Horgan's grading scale of RM was evaluated throughout the 24-month follow-up. Intraocular pressure (IOP) and possible complications were also recorded. RESULTS Nine eyes of 9 patients were included. A mean of 4.4 ± 1.2 injections were given over the 24 months. At the end of follow-up, mean BCVA was significantly improved, from 0.9 ± 0.19 logMAR at baseline to 0.56 ± 0.3 logMAR (P = 0.028), and mean CFT was significantly decreased, from 546 ± 123 μm at baseline to 223 ± 34 μm (P < 0.001). Intravitreal aflibercept lowered baseline maculopathy stage as well. No significant change in IOP values and no complications, such as endophthalmitis, was recorded. CONCLUSION Intravitreal aflibercept is an effective treatment for patients with radiation-induced macular edema, allowing functional and anatomical improvements to be achieved with a relatively low number of injections.

An efficacy comparison of anti-vascular growth factor agents and laser photocoagulation in diabetic macular edema: a network meta-analysis incorporating individual patient-level data. BMC Ophthalmol 2018; 18:340. [PMID: 30591022 PMCID: PMC6307247 DOI: 10.1186/s12886-018-1006-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2018] [Accepted: 12/10/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND This was an updated network meta-analysis (NMA) of anti-vascular endothelial growth factor (VEGF) agents and laser photocoagulation in patients with diabetic macular edema (DME). Unlike previous NMA that used meta-regression to account for potential confounding by systematic variation in treatment effect modifiers across studies, this update incorporated individual patient-level data (IPD) regression to provide more robust adjustment. METHODS An updated review was conducted to identify randomised controlled trials for inclusion in a Bayesian NMA. The network included intravitreal aflibercept (IVT-AFL) 2 mg bimonthly (2q8) after 5 initial doses, ranibizumab 0.5 mg as-needed (PRN), ranibizumab 0.5 mg treat-and-extend (T&E), and laser photocoagulation. Outcomes included in the analysis were change in best-corrected visual acuity (BCVA), measured using an Early Treatment Diabetic Retinopathy Study (ETDRS) chart, and patients with ≥10 and ≥ 15 ETDRS letter gains/losses at 12 months. Analyses were performed using networks restricted to IPD-only and IPD and aggregate data with (i) no covariable adjustment, (ii) covariable adjustment for baseline BVCA assuming common interaction effects (against reference treatment), and (iii) covariable adjustments specific to each treatment comparison (restricted to IPD-only network). RESULTS Thirteen trials were included in the analysis. IVT-AFL 2q8 was superior to laser in all analyses. IVT-AFL 2q8 showed strong evidence of superiority (95% credible interval [CrI] did not cross null) versus ranibizumab 0.5 mg PRN for mean change in BCVA (mean difference 5.20, 95% CrI 1.90-8.52 ETDRS letters), ≥15 ETDRS letter gain (odds ratio [OR] 2.30, 95% CrI 1.12-4.20), and ≥10 ETDRS letter loss (OR 0.25, 95% CrI 0.05-0.74) (IPD and aggregate random-effects model with baseline BCVA adjustment). IVT-AFL 2q8 was not superior to ranibizumab 0.5 mg T&E for mean change in BCVA (mean difference 5.15, 95% CrI -0.26-10.61 ETDRS letters) (IPD and aggregate random-effects model). CONCLUSIONS This NMA, which incorporated IPD to improve analytic robustness, showed evidence of superiority of IVT-AFL 2q8 to laser and ranibizumab 0.5 mg PRN. These results were irrespective of adjustment for baseline BCVA.

Vision-related quality of life: 12-month aflibercept treatment in patients with treatment-resistant neovascular age-related macular degeneration. Graefes Arch Clin Exp Ophthalmol 2016; 255:475-484. [PMID: 27572301 DOI: 10.1007/s00417-016-3477-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2016] [Revised: 08/08/2016] [Accepted: 08/17/2016] [Indexed: 11/29/2022] Open
Abstract
PURPOSE To assess changes in vision-related quality of life (VR-QoL) among patients with treatment-resistant neovascular age-related macular degeneration (nAMD) following intravitreal aflibercept treatment over 48 weeks. METHODS We conducted a prospective study in which 49 patients with nAMD resistant to anti-vascular endothelial growth factor therapy were switched to intravitreal aflibercept. Patients were treated with three loading doses every 4 weeks followed by injections every 8 weeks, for a total of 48 weeks. Ophthalmic examinations performed at each visit included best-corrected visual acuity (BCVA) and central macular thickness (CMT) measurement. The National Eye Institute Visual Functioning Questionnaire 25 (NEI VFQ-25) was used to assess VR-QoL at baseline and weeks 24 and 48. Changes in NEI VFQ-25 composite and subscale scores were analyzed using paired t tests. The relationship between the change in VR-QoL and changes in BCVA and CMT, and the impact of the better-seeing eye (BSE, defined as the eye reading the greater number of letters at baseline) vs. the worse-seeing eye (WSE, the fellow eye to the BSE) were assessed. RESULTS Mean NEI VFQ-25 composite scores improved significantly at weeks 24 and 48 compared to baseline (4.5 ± 9.2 and 4.4 ± 11.8, respectively, all p < 0.01). Among subscales, general vision and near and distance activities showed significant improvements at weeks 24 and 48 (all p < 0.05). Improvement in the NEI VFQ-25 composite score was significantly associated with increased BCVA at week 48 (β coefficient = 0.43, p = 0.029), but not with change in CMT (β coefficient = -0.007, p = 0.631). There was no association between VR-QoL changes and BSE or WSE. CONCLUSION Despite previous anti-VEGF treatment in this cohort, overall VR-QoL improved following aflibercept therapy over 48 weeks. This improvement was related to improved vision in treatment eyes regardless of whether they were the BSE or WSE.
