Abstract
BACKGROUND The objectives of this study were to evaluate the safety profile of aflibercept and health-related quality of life (HRQL) in patients with metastatic colorectal cancer (mCRC) provided with aflibercept access before marketing authorization. PATIENTS AND METHODS Patients received aflibercept followed by FOLFIRI (fluorouracil, leucovorin, irinotecan) on day 1 of a 2-week cycle until disease progression, unacceptable toxicity, death, or patient/investigator decision to discontinue. Treatment-emergent adverse events (TEAEs) were evaluated, and HRQL was assessed at baseline, cycle 3, and every other cycle using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30, EORTC QLQ-CR29, and EuroQol 5-Dimensions 3-Levels questionnaires (NCT01571284). RESULTS Overall, 779 adult patients with mCRC, who received ≥ 1 prior oxaliplatin-based regimen and had disease progression during or following their last administration of oxaliplatin-based chemotherapy, were enrolled. At data cutoff, all patients had discontinued treatment, mainly owing to disease progression (51.7%). The most common TEAEs of any grade were diarrhea (61.6%), hypertension (48.4%), and nausea (43.3%). The most common grade 3/4 TEAEs were hypertension (24.1%), neutropenia (23.1%), and diarrhea (15.3%). Clinically meaningful changes in HRQL were reported for all measures. Most patients either had an improvement in their HRQL scores or remained stable during the treatment period based on patient-reported outcomes. CONCLUSION The data from this study support the tolerability of the combination of aflibercept and FOLFIRI in a setting that more closely approximates real life in patients with mCRC who failed to respond to oxaliplatin-based chemotherapy, and also suggest an improvement in HRQL.

Abstract
PURPOSE To examine vision-related quality of life in patients with diabetic macular edema (DME) treated with intravitreal aflibercept (EYLEA, Regeneron Pharmaceuticals, Inc, Tarrytown, NY). DESIGN AQUA was a multicenter, open-label, single-arm, phase 4 study. PARTICIPANTS Adults 18 years of age or older with type 1 or 2 diabetes mellitus and DME. METHODS Patients received intravitreal aflibercept 2 mg every 8 weeks for 52 weeks, after 5 initial doses every 4 weeks. MAIN OUTCOME MEASURES The primary outcome was the change in 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) total score from baseline to week 52. Secondary outcomes included the change in NEI VFQ-25 near and distant activities subscale scores, best-corrected visual acuity (BCVA; Early Treatment Diabetic Retinopathy Study [ETDRS] letters), and central retinal thickness (CRT) from baseline to week 52. Change in NEI VFQ-25 score at week 52 for better-seeing eyes (BSEs) and worse-seeing eyes (WSEs) also was evaluated. RESULTS A total of 553 patients comprised the full analysis set, and 560 patients comprised the safety analysis set. At baseline, the mean NEI VFQ-25 total score was 70.12, mean BCVA was 61.5 ETDRS letters, and mean CRT was 464.81 μm. A mean of 8.8 injections were administered over 52 weeks. At week 52, the mean improvement from baseline in the NEI VFQ-25 total score was +6.11 (standard deviation [SD], 11.46); the corresponding improvements in near and distant activities were +11.37 (SD, 18.01) and +7.33 (SD, 17.32), respectively. Similarly, improvements in patients whose BSE and WSE were treated were 7.74 (SD, 13.59) and 5.48 (SD, 9.70), respectively. At week 52, mean change in BCVA was +10.0 ETDRS letters (SD, 8.0 ETDRS letters), and mean change in CRT was -175.38 μm (SD, 132.62 μm). Overall, 53.6% of patients reported treatment-emergent adverse events (TEAEs), of whom 26.8% experienced an ocular TEAE in the study eye. The most common serious ocular TEAE was endophthalmitis (0.5% [n = 3]). Five deaths (0.9%) were reported, but were not considered treatment related. CONCLUSIONS Intravitreal aflibercept was associated with clinically meaningful improvements in NEI VFQ-25 total score over 52 weeks in patients with DME; these were even more pronounced for near than for distant activities. Adverse events were consistent with the known safety profile of intravitreal aflibercept.

Abstract
PURPOSE To evaluate the efficacy and safety of intravitreal aflibercept injection (IAI) in Japanese patients with diabetic macular edema (DME). METHODS VIVID-DME was a Phase 3 study comprising patients with DME randomized 1:1:1 to IAI 2 mg every 4 weeks (2q4), IAI 2 mg every 4 weeks until Week 16 then 8-week dosing (2q8), and laser. A total of 403 patients (76 Japanese) were included in this study. VIVID-Japan (72; all Japanese patients) was a nonrandomized, open-label study comprising Japanese patients with DME receiving IAI 2q4 until Week 16, then 2q8. Primary efficacy endpoint (Week 52) of VIVID-DME was mean change from baseline in best-corrected visual acuity; VIVID-Japan evaluated safety and tolerability. RESULTS Mean change in best-corrected visual acuity (letters) for 2q4, 2q8, and laser groups was +10.6, +10.9, and +1.2 and +9.8, +9.5, and +1.1 in the non-Japanese and Japanese populations of VIVID-DME, respectively. In VIVID-Japan, it was +9.3 for IAI 2q8. Intravitreal aflibercept injection also provided consistently greater benefits for anatomical outcomes versus laser. Adverse events were consistent with the known safety profile of IAI. CONCLUSION In Japanese patients with DME, IAI treatment was superior to laser for visual and anatomical outcomes and resulted in efficacy and safety outcomes similar to those in a non-Japanese patient population.

BMC ophthalmology. 2019;(1):123
Abstract
BACKGROUNDS To assess the changes in individual retinal layer thickness and visual function associated with gains in visual acuity after an intravitreal conbercept injection in the diabetic macular edema (DME) on spectral domain optical coherence tomography (SD-OCT) and microperimetry during 1-year follow-up. METHODS Retrospective observational study. Twenty patients with clinically significant DME in the study eye were imaged by SD-OCT every 3 months and MP1 microperimeter in the third month while receiving anti-vascular endothelial growth factor (VEGF) (conbercept) treatment. In each patient, seven retinal layers were segmented in 98 scans covering a 6 mm × 6 mm area of the macula at baseline and during 1 year of treatment. An automatic, full-threshold microperimetry of the central field (10° × 10°, 40 stimulated points) with the MP1 microperimeter. Thickness and microperimetry changes were quantitatively measured and evaluated for their correlation with increases in visual acuity. RESULTS Although thicknesses of the inner nuclear layer (INL) and the outer nuclear layer (ONL) were reduced the most after treatment (p < 0.05), decreases of the ganglion cell layer (GCL) (r = 0.591, p = 0.006) and inner plexiform layer (IPL) (r = 0.663, p = 0.001) in central subfield area was associated with best-corrected visual acuity (BCVA) gain, and had the best estimation of BCVA gain (adjust R2 = 0.544). Mean macular sensitivity in the central subfield was also well correlated with BCVA gain (r = 0.531, p = 0.016). CONCLUSIONS Neural recovery occurred after the resolution of edema during conbercept treatment, due to the decreases in GCL and IPL associating with gains in vision and improved microperimetry.

Ophthalmic surgery, lasers & imaging retina. 2019;(11):684-690
Abstract
BACKGROUND AND OBJECTIVE To report the correlation of central macular thickness (CMT) and best-corrected visual acuity (BCVA) after 1-year treatment by two doses (2.5 mg or 1.25 mg) of intravitreal ziv-aflibercept (IVZ) versus bevacizumab (IVB) in eyes with diabetic macular edema (DME). PATIENTS AND METHODS In this study, the correlation of CMT and BCVA changes of the eyes enrolled in a previous clinical trial of 123 eyes were re-evaluated. The correlation of BCVA and CMT changes at each visit was evaluated in the three study arms individually. Then, the eyes in each of the arms were classified at each follow-up visit into three subgroups based on their CMT changes related to the baseline CMT: CMT decrease of 30% or more of baseline CMT, between 10% to 29% of baseline CMT, and less than 9% of baseline CMT or CMT increase. RESULTS BCVA and CMT changes were correlated significantly (P < .05) in all and in half of the follow-up visits, respectively, in the eyes treated by IVZ 1.25 mg and IVB (r = 0.554 and r = 0.617 at 1 year, respectively). Nevertheless, such a significant correlation was not detected in the eyes treated by IVZ 2.5 mg in any of the follow-up visits (r = 0.202 at 1 year; P = .259). In the IVZ 2.5 mg group, BCVA improvement was observed in all subgroups with each level of CMT reductions. CONCLUSION Ziv-aflibercept 2.5 mg might have a beneficial effect on DME beyond thickness reduction. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:684-690.].

Abstract
PURPOSE To investigate retinal fluid features and ellipsoid zone (EZ) integrity dynamics on spectral-domain OCT (SD-OCT) in eyes with diabetic macular edema (DME) treated with intravitreal aflibercept injection (IAI) in the VISTA-DME study. DESIGN A post hoc subanalysis of a phase III, prospective clinical trial. PARTICIPANTS Eyes received either IAI 2 mg every 4 weeks (2q4) or every 8 weeks after 5 initial monthly doses (2q8). METHODS All eyes from the VISTA Phase III study in the IAI groups imaged with the Cirrus HD-OCT system (Zeiss, Oberkochen, Germany) were included. The OCT macular cube datasets were evaluated using a novel software platform to generate retinal layer and fluid boundary lines that were manually corrected for assessment of change in EZ parameters and volumetric fluid parameters from baseline. The retinal fluid index (i.e., proportion of the retinal volume consisting of cystic fluid) was also calculated at each time point. MAIN OUTCOME MEASURES The feasibility of volumetric assessment of higher-order OCT-based retinal parameters and its correlation with best-corrected visual acuity (BCVA). RESULTS Overall, 106 eyes of 106 patients were included. Specifically, 52 eyes of 52 patients were included in the IAI 2q4 arm, and 54 eyes of 54 patients were included in the IAI 2q8 arm. Ellipsoid zone integrity metrics significantly improved from baseline to week 100, including central macular mean EZ to retinal pigment epithelium (RPE) thickness (2q4: 26.6 μm to 31.6 μm, P < 0.001; 2q8: 25.2 μm to 31.4 μm, P < 0.001). At week 100, central macular intraretinal fluid volume was reduced by >65% (P < 0.001) and central macular subretinal fluid volume was reduced by >99% in both arms (P < 0.001). Central macular retinal fluid index (RFI) significantly improved in both arms (2q4: 17.9% to 7.2%, P < 0.001; 2q8: 19.8% to 4.2%, P < 0.001). Central macular mean EZ-RPE thickness (i.e., a surrogate for photoreceptor outer segment length) and central RFI were independently correlated with BCVA at multiple follow-up visits. CONCLUSIONS Intravitreal aflibercept injection resulted in significant improvement in EZ integrity and quantitative fluid metrics in both 2q4 and 2q8 arms and correlated with visual function.

Plaza-Ramos, P, Borque, E, García-Layana, A
PloS one. 2019;(10):e0223793
Abstract
PURPOSE To evaluate the efficacy and safety of ranibizumab and aflibercept in the treatment of diabetic macular edema in a real world study, and to compare the two treatments with each other. METHODS Retrospective observational study of 213 eyes from 141 patients with diabetic macular edema was completed between June 2014 and June 2016. 122 were treated with ranibizumab intravitreal injection and 91 with aflibercept intravitreal injection, with a loading phase of 3 injections and a Pro Re Nata protocol. The drug was selected by the physician and fluorescein angiography was performed by physician`s criteria. Re-treatment was performed when a decline in BCVA, an increase of central macular thickness or an increase or persistence of intraretinal fluid in OCT was observed. The primary outcome was the mean change in best corrected visual acuity at 1 year, while central macular thickness, central macular volume, the number of injections and visits were evaluated as secondary outcomes. The correlation between BCVA at 4th month visit and BCVA at 12th month visit was also evaluated. RESULTS The mean baseline best corrected visual acuity for the eyes treated with ranibizumab was 0.55 (+/- 0.35) logMAR, and with aflibercept it was 0.48 (+/- 0.29) (P = 0.109). Best corrected visual acuity improved in both groups, and at the end of the follow-up was 0.40 (+/- 0.35) in the ranibizumab group and 0.40 (+/- 0.29) in the aflibercept group (P = 0.864). Best corrected visual acuity at 4th month visit is correlated at a high value (R = 0.789) with the one at the end of the study. No differences were found in central macular thickness, central macular volume and glycosylated hemoglobin when adjusting with baseline values. The overall number of injections was 5.77 (+/- 2.01), being 5.56 (+/- 2.0) in the ranibizumab group and 6.07 (+/- 1.99) in the aflibercept group (P = 0.069). The main outcome determining final best corrected visual acuity was the baseline best corrected visual acuity (P<0.001). CONCLUSION There are no differences in efficacy between ranibizumab and aflibercept in diabetic macular edema treatment in this real world study.

Ophthalmic surgery, lasers & imaging retina. 2019;(3):167-173
Abstract
BACKGROUND AND OBJECTIVE To evaluate the effect of baseline factors on differences in vision gains with intravitreal aflibercept injection (IAI) versus laser control in patients with diabetic macular edema (DME). PATIENTS AND METHODS This was an integrated post-hoc subanalysis of two phase 3 trials (VISTA, VIVID) in patients with DME. Least square (LS) mean differences of patients treated with IAI compared to laser control in best-corrected visual acuity (BCVA) change from baseline at week 100 were evaluated for association with baseline demographics and baseline systemic disease characteristics. RESULTS At week 100, LS mean differences in BCVA change from baseline with IAI compared to laser control were not significant for association with baseline age, gender, and race or status of glycosylated hemoglobin, body mass index, renal impairment, hypertension, cerebrovascular disease, and ischemic heart disease. CONCLUSION Vision gains with IAI were significantly greater than laser control and were not influenced by demographics and systemic disease control at baseline.

Graefe's archive for clinical and experimental ophthalmology = Albrecht von Graefes Archiv fur klinische und experimentelle Ophthalmologie. 2019;(7):1373-1380
Abstract
PURPOSE To assess the impact of micropulsed laser (MPL) on modifying the number of aflibercept injections when used as an adjuvant therapy in diabetic macular edema (DME). METHODS A prospective randomized interventional clinical study included patients with DME attending Al Hadi Clinic, Kuwait, during the period from May 2017 to December 2018. Patients were allocated in two groups; group A received aflibercept injections alone and group B received combined aflibercept injections followed by MPL within a week. The primary outcome was the number of Aflibercept injections in each group guided by the change in central macular thickness (CMT). All the patients were followed for 18 months. Secondary outcome measures included best corrected visual acuity (BCVA), contrast sensitivity (CS), and any recorded complications. RESULTS Fifty-four eyes of 51 patients were included (27 in each group). There was no statistically significant difference between the two groups in baseline characteristics except for the age that was statistically higher in group B (p = 0.001). The number of injections were significantly lower in group B (4.1 ± 1.1) than group A (7.3 ± 1.1) (p < 0.005). At 18th month, there was significant reduction in CMT in both groups (p < 0.005) with no statistical difference between the two groups (p = 0.989). Final BCVA in both groups showed statistically significant improvement (p < 0.005) without statistically significant difference between the two groups (p = 0.082). In both groups, the CS showed significant improvement from baseline (p < 0.005). No ocular or systemic adverse effects were observed in either group. CONCLUSION Supplemental MPL in eyes with DME may decrease the burden of the aflibercept injection frequency while resulting in comparable anatomical and visual outcomes.
