Abstract
PURPOSE To describe the sociodemographic, medical and management characteristics of patients using intravitreal (IVT) anti-vascular endothelial growth factors (VEGF) in France. METHODS An observational study was conducted in patients treated with IVT ranibizumab or aflibercept, aged 18 years or older using the French National Health Insurance Databases covering 99% of the French population. Patients currently treated in 2018 were included in a cross-sectional approach to describe treatment history over the previous 6 years. Patients newly treated between 2014 and 2018 were included in a longitudinal approach to describe treatment management during up to 6 years of follow-up. Sociodemographic characteristics and medical history were described in both populations. The analyses were performed at the patient level, as no distinction between the eyes could be made. RESULTS A total of 224 775 current users of IVT anti-VEGF in 2018 (mean age 78.1 ± 11.3 years, 60% female) and 330 969 new users between 2014 and 2018 (mean age 75.9 ± 12.0 years, 59% female) were included. In both populations cardiovascular comorbidities or risk factors were frequent and the main treatment indications were age-related macular degeneration and diabetic macular oedema. Among current users of IVT anti-VEGF in 2018, the mean number of years receiving a treatment was 2.9 ± 2.0 years, with a mean of 13.7 ± 11.8 dispensations. In the longitudinal approach, a 26% increase in IVT anti-VEGF initiation was observed between 2014 and 2018. For new users, the mean number of years receiving a treatment was 1.6 ± 1.6 and 67% had at least three dispensations within the first three months. A treatment interruption was observed for 83% of new users and occurred on average of 6.1 ± 8.1 months after initiation. The mean number of dispensations was 4.8 ± 2.8 in the first year and 2.2 ± 2.9 in the second year. The mean number of eye monitoring examinations was 6.5 ± 4.7 in the first year and 4.6 ± 4.4 in the second year. CONCLUSION This study described the real-world conditions of IVT anti-VEGF dispensing at the entire French population scale. Less frequent dispensations and surveillance examinations were observed than in monthly schemes applied in registration trials for IVT anti-VEGF. These results may indicate a lack of systematic monitoring associated with fewer injections and/or clinicians' preference for more flexible and personalized injection schemes than those originally recommended.

Abstract
PURPOSE To quantify changes of the retinal vascular bed area (RVBA) in mm2 on stereographically projected ultrawide field fluorescein angiography images in eyes with proliferative diabetic retinopathy after antivascular endothelial growth factor injection. METHODS This is a prospective, observational study. The early-phase ultrawide field fluorescein angiography images (Optos 200Tx) of 40 eyes with proliferative diabetic retinopathy and significant nonperfusion obtained at baseline and after six months (NCT02863354) were stereographically projected by correcting peripheral distortion. The global retinal vasculature on ultrawide field fluorescein angiography was extracted for calculating RVBA by summing the real size (mm2) of all the pixels automatically. RESULTS For the entire cohort, the global RVBA for the entire retina decreased from 67.1 ± 15.5 to 43.6 ± 18.8 mm2 after anti-VEGF treatment at six months (P < 0.001). In the subgroup receiving monthly anti-VEGF injections, the global RVBA decreased from 68.7 ± 16.2 to 33.9 ± 13.3 mm2 (P < 0.001). In the subgroup receiving anti-VEGF every three months, the global RVBA decreased from 65.6 ± 15.1 to 50.8 ± 19.3 mm2 (P = 0.004). CONCLUSION RVBA seems to be a new biomarker to indicate efficiency of retinal vascular changes after anti-VEGF injection. Eyes with proliferative diabetic retinopathy and significant nonperfusion demonstrate reduced RVBA after anti-VEGF treatment.

Abstract
BACKGROUND Diabetes is a major risk factor for erectile dysfunction, however, the effect of GLP-1 receptor agonists on erectile dysfunction is unknown. We aimed to assess the incidence, prevalence, and progression of erectile dysfunction in men treated with dulaglutide compared with placebo, and to determine whether dulaglutide's effect on erectile dysfunction was consistent with its effect on other diabetes-related outcomes. METHODS The Researching Cardiovascular Events with a Weekly Incretin in Diabetes (REWIND) trial was a double-blind, placebo-controlled randomised trial of the effect of dulaglutide on cardiovascular outcomes. REWIND was done at 371 sites in 24 countries. Men and women aged older than 50 years with type 2 diabetes, who had either a previous cardiovascular event or cardiovascular risk factors, were randomly assigned (1:1) to receive either dulaglutide or placebo. Participating men were offered the opportunity to complete the standardised International Index of Erectile Function (IIEF) questionnaire at baseline, 2 years, 5 years, and study end. We did an exploratory analysis, in which we included participants who completed a baseline and at least 1 follow-up IIEF questionnaire. The primary outcome for these analyses was the first occurrence of moderate or severe erectile dysfunction following randomisation, assessed by the erectile function subscores on IIEF. This analysis was part of the REWIND trial, which is registered with ClinicalTrials.gov, NCT01394952. FINDINGS Between Aug 18, 2011, and Aug 14, 2013, 3725 (70·1%) of 5312 male participants with a mean age of 65·5 years (SD 6·4 years) were analysed, of whom 1487 (39·9%) had a history of cardiovascular disease, and 2104 (56·5%) had moderate or severe erectile dysfunction at baseline. The incidence of erectile dysfunction following randomisation was 21·3 per 100 person-years in the dulaglutide group and 22·0 per 100 person-years in the placebo group (HR 0·92, 95% CI 0·85-0·99, p=0·021). Men in the dulaglutide group also had a lesser fall in erectile function subscore compared with the placebo group, with a least square mean difference of 0·61 (95% CI 0·18-1·05, p=0·006). INTERPRETATION Long-term use of dulaglutide might reduce the incidence of moderate or severe erectile dysfunction in men with type 2 diabetes. FUNDING Eli Lilly and Company.

Abstract
OBJECTIVE Onasemnogene abeparvovec, a one-time intravenous gene replacement therapy, and nusinersen, an antisense oligonucleotide that requires ongoing intrathecal administration, have been evaluated as treatments for spinal muscular atrophy (SMA) type 1 in separate Phase III trials, but no head-to-head comparison studies have been conducted. Onasemnogene abeparvovec was compared with nusinersen using a matching-adjusted indirect comparison (MAIC) to estimate the treatment effect of onasemnogene abeparvovec relative to nusinersen for the treatment of symptomatic patients with SMA type 1 for up to 24 months of follow-up. METHODS In the absence of studies for both onasemnogene abeparvovec and nusinersen with a common comparator, a Bayesian naïve indirect treatment comparison (ITC) and MAIC between onasemnogene abeparvovec and nusinersen were conducted to compare efficacy and safety of onasemnogene abeparvovec with nusinersen. Outcomes of interest were event-free survival (EFS), overall survival (OS), and motor milestone achievements (independent sitting and independent walking). Relative treatment effects were expressed as relative risk (RR) and risk difference. RESULTS Pooled and weighted patient-level data illustrated a favorable effect toward onasemnogene abeparvovec, suggesting longer EFS for patients compared with nusinersen (HR of onasemnogene abeparvovec vs. nusinersen: 0.19 [95% CI: 0.07-0.54; 99% CI: 0.05-0.74]). At 24 months of follow-up, patients receiving onasemnogene abeparvovec were statistically significantly more likely to achieve the motor milestone of sitting independently compared with patients treated with nusinersen. Although statistically significant differences were not observed at 6 to 18 months between treatment options, the likelihood of sitting independently at 12 and 18 months numerically favored onasemnogene abeparvovec. A numerically greater likelihood of walking by 18 and 24 months was also observed for patients treated with onasemnogene abeparvovec compared with nusinersen. Onasemnogene abeparvovec therapy was also associated with a favorable (but statistically nonsignificant) outcome for OS and may be associated with prolonged survival compared with nusinersen (HR of onasemnogene abeparvovec vs. nusinersen: 0.35 [95% CI: 0.09-1.32; 99% CI: 0.06-2.01]). Bayesian naïve ITC results were similar to the MAIC analysis for EFS, OS, and motor milestone achievements. Small sample size limited covariate matching to baseline CHOP INTEND and nutritional support requirement, leading to wider CIs and statistically inconclusive outcomes for some of the results. CONCLUSIONS Despite limitations of the current MAIC analysis (mainly a small sample size for statistical testing, even for the pooled onasemnogene abeparvovec trials, and potential differences in prognostic and predictive factors between studies), the relative treatment effects in EFS, OS, and motor milestone achievement indicate that onasemnogene abeparvovec may offer continued benefit compared with nusinersen through 24 months of follow-up.

Abstract
Colorectal cancer is the second leading cause of cancer-related death worldwide. For metastatic colorectal cancer (mCRC) patients, it is recommended, as first-line treatment, chemotherapy (CT) based on doublet cytotoxic combinations of fluorouracil, leucovorin, and irinotecan (FOLFIRI) and fluorouracil, leucovorin, and oxaliplatin (FOLFOX). In addition to CT, biological (targeted agents) are indicated in the first-line treatment, unless contraindicated. In this context, most of mCRC patients are likely to progress and to change from first line to second line treatment when they develop resistance to first-line treatment options. It is in this second line setting where Aflibercept offers an alternative and effective therapeutic option, thought its specific mechanism of action for different patient's profile: RAS mutant, RAS wild-type (wt), BRAF mutant, potentially resectable and elderly patients. In this paper, a panel of experienced oncologists specialized in the management of mCRC experts have reviewed and selected scientific evidence focused on Aflibercept as an alternative treatment.

Ophthalmology. Retina. 2021;(5):409-419
Abstract
PURPOSE To evaluate the effect of intravitreal aflibercept on diabetic retinopathy (DR) severity and visual function in patients with proliferative DR (PDR) without diabetic macular edema (DME). DESIGN Prospective, longitudinal, multicenter clinical trial. PARTICIPANTS Forty eyes of 40 patients with PDR and no DME were enrolled in this study. Patients were randomized into monthly and quarterly 2-mg aflibercept injection cohorts and were treated over a period of 12 months. METHODS All patients underwent ultra-widefield fundus imaging including pseudocolor and fluorescein angiography using an Optos 200Tx device. MAIN OUTCOME MEASURES Severity of DR at baseline, month 6, and month 12 was evaluated using the DR severity scale (DRSS). The DRSS scores were correlated with the 25-item Visual Function Questionnaire (VFQ-25) and 39-item Visual Function Questionnaire (VFQ-39) scores at baseline and month 12. RESULTS Mean age of the patients was 48.2 years (range, 25-75 years), mean duration of diabetes mellitus was 16.1 years (range, 2-36 years), and median glycated hemoglobin level was 8.8% (IQR, 7.4%-10%). Both monthly and quarterly groups demonstrated a statistically significant regression in DRSS from baseline to month 12 (P < 0.001). The monthly group demonstrated a statistically significant greater regression of DRSS score at the month 6 visit compared with the quarterly group (P = 0.019). However, the difference between the two groups became statistically insignificant at month 12 visit (P = 0.309). Also no difference was found in mean VFQ-25 and VFQ-39 composite scores between the monthly and quarterly groups at month 12 (P = 0.947 and P = 0.921, respectively). The improvement in mean VFQ-25 and VFQ-39 composite scores at month 12 was correlated significantly with improvement in DRSS score (r = 0.384 and P = 0.039, and r = 0.361 and P = 0.046, respectively). CONCLUSIONS In this study of eyes with PDR without DME, both monthly and quarterly aflibercept injection groups showed significant improvement in DR severity at month 12 compared with baseline. The improvement in DRSS score was associated with an improvement in VFQ-25 and VFQ-39 composite score.

Abstract
PURPOSE To assess the influence of baseline choroidal neovascularization (CNV) features on visual change and fluid resolution after anti-vascular endothelial growth factor (VEGF) treatment of eyes with neovascular age-related macular degeneration (nAMD). DESIGN Post hoc analysis of 52-week data from the phase 3 Vascular Endothelial Growth Factor VEGF Trap-Eye: Investigation of Efficacy and Safety in Wet Age-Related Macular Degeneration (AMD) Studies (VIEW) 1 and 2 clinical trials. PARTICIPANTS One thousand eight hundred four patients with nAMD. METHODS Integrated data from VIEW 1 and 2 of 1804 eyes receiving intravitreal aflibercept injections (IAIs) 2 mg every 4 weeks, IAIs 2 mg every 8 weeks after 3 initial monthly doses, and ranibizumab every 4 weeks with documented baseline CNV type, total area, and leakage area were analyzed. Time to an event and cumulative incidence were evaluated by Kaplan-Meier analysis, and relative risks were estimated using proportional hazards analysis. MAIN OUTCOMES MEASURES Cumulative incidence of time to first sustained vision gain of 15 or more Early Treatment Diabetic Retinopathy Study letters, vision loss of more than 5 Early Treatment Diabetic Retinopathy Study letters from baseline, as well as first sustained absence of retinal fluid and intraretinal fluid as evaluated by OCT with respect to CNV type, total CNV, and leakage area. RESULTS Eyes with predominantly classic CNV (mean best-corrected visual acuity [BCVA], 48.2 letters at baseline) showed a higher incidence rate of first sustained gain of 15 letters or more than eyes with occult CNV (mean BCVA, 57.9 letters at baseline; P < 0.01). Eyes with occult CNV at baseline showed higher incidence rates of first sustained absence of retinal fluid and of intraretinal fluid than eyes with predominantly classic CNV (both P < 0.01). With increasing baseline CNV total area and leakage area, the incidence rate of first sustained gain of 15 letters or more decreased. CONCLUSIONS This post hoc analysis provided additional evidence for the role of baseline CNV features (CNV type, total area, and leakage area) in influencing visual and anatomic outcomes in eyes with nAMD after anti-VEGF treatment.

Abstract
BACKGROUND/AIMS: Quantifying microaneurysms (MAs) turnover may be an objective measure for therapeutic response in diabetic retinopathy. This study assesses changes in MA counts on ultra-widefield fluorescein angiography (UWFA) in subjects undergoing treatment with intravitreal aflibercept injection (IAI) for proliferative diabetic retinopathy (PDR) in the Intravitreal Aflibercept for Retinal Non-Perfusion in Proliferative Diabetic Retinopathy(RECOVERY) study using an automated MA detection platform. METHODS RECOVERY is a prospective study that enrolled 40 subjects with PDR randomised 1:1 to receive 2 mg IAI every 4 weeks(q4wk) or every 12 weeks (q12wk). UWFA images were obtained at baseline, 6 months and 1 year. Images were analysed using an automated segmentation platform to detect and quantify MAs. Zones 1, 2 and 3 correspond to the macula, mid-periphery and far-periphery, respectively. RESULTS The q4wk cohort demonstrated a significant decline in MAs in all zones and panretinally at baseline versus month 6, baseline versus year 1, and month 6 versus year 1 (-20.0% to -61.8%; all p<0.001). In the q12wk cohort, baseline versus month 6 showed a significant decline panretinally (mean: -34.2%; p<0.001) and in zone 3 (mean -44.18%; p<0.001). Addiitonally, baseline to year 1 in the q12wk group demonstrated significant decline panretinally (mean: -47.7%; p<0.001) and in zone 3 (mean: -59.8%; p<0.001). All zones demonstrated significantly decline from month 6 to year 1 in the q12wk group. CONCLUSION Therapy with IAI demonstrates significantly reduced panretinal MA counts in PDR at 1 year in both treatment groups. The use of automated platforms to detect and quantify MAs may provide a novel imaging marker for evaluating disease activity and therapeutic impact. TRIAL REGISTRATION NUMBER NCT02863354.

Abstract
PURPOSE To report the 2-year efficacy and safety of abicipar every 8 weeks and quarterly (after initial doses) compared with monthly ranibizumab in patients with treatment-naïve neovascular age-related macular degeneration (nAMD). DESIGN Two multicenter, randomized, phase 3 clinical trials with identical protocols (CEDAR and SEQUOIA). Analyses used pooled trial data. PARTICIPANTS The trials enrolled 1888 patients (1 eye/patient) with active choroidal neovascularization secondary to age-related macular degeneration and best-corrected visual acuity (BCVA) of 24 to 73 Early Treatment Diabetic Retinopathy Study letters. METHODS At enrollment, patients were assigned to study eye treatment with abicipar 2 mg every 8 weeks after initial doses at baseline and weeks 4 and 8 (abicipar Q8, n = 630), abicipar 2 mg every 12 weeks after initial doses at baseline and weeks 4 and 12 (abicipar Q12, n = 628), or ranibizumab 0.5 mg every 4 weeks (ranibizumab Q4, n = 630). MAIN OUTCOME MEASURES Efficacy measures included stable vision (<15-letter loss in BCVA from baseline) and change from baseline in BCVA and central retinal thickness (CRT). Safety measures included adverse events (AEs). RESULTS For patients who completed the study, efficacy of abicipar after initial doses was maintained through week 104. At week 104, the proportion of patients with stable vision was 93.0% (396/426), 89.8% (379/422), and 94.4% (470/498); mean change in BCVA from baseline was +7.8 letters, +6.1 letters, and +8.5 letters, and mean change in CRT from baseline was -147 μm, -146 μm, and -142 μm in the abicipar Q8 (14 injections), abicipar Q12 (10 injections), and ranibizumab Q4 (25 injections) groups, respectively. The overall incidence of intraocular inflammation (IOI) AEs was 15.4%, 15.3%, and 0.3% from baseline through week 52 and 16.2%, 17.6%, and 1.3% from baseline through week 104 in the abicipar Q8, abicipar Q12, and ranibizumab Q4 groups, respectively. CONCLUSIONS Two-year results show efficacy of abicipar Q8 and Q12 in nAMD. First onset of IOI events with abicipar was much reduced in the second year and comparable with ranibizumab (0.8% and 2.3% vs. 1.0%). The extended duration of effect of abicipar allows for quarterly dosing and reduced treatment burden.

Abstract
PURPOSE To prospectively evaluate the outcomes of different subtypes of neovascular age-related macular degeneration during intravitreal aflibercept monotherapy. METHODS Forty-four eyes of 44 patients with treatment-naïve polypoidal choroidal vasculopathy (PCV, n = 12), hemorrhagic choroidal neovascularization (hCNV, n = 12), pigment epithelium detachment (PED, n = 11), or retinal angiomatous proliferation (RAP, n = 9) were included and followed for 12 months. All patients received intravitreal aflibercept monotherapy. RESULTS Mean visual acuity at baseline in PCV was 67 ± 16 Early Treatment Diabetic Retinopathy Study letters (20/50 Snellen equivalent), in hCNV 55 ± 21 (20/80), in RAP lesions 64 ± 11 (20/50), and in PED 74 ± 7 (20/32). At Month 12, visual acuity in PCV was 66 ± 16 (20/50), in hCNV 69 ± 17 (20/40), in RAP 68 ± 12 (20/50), and in PED 69 ± 18 (20/40). At the 12-month follow-up, visual acuity improved or was stable (±5 letters from baseline) in 84% of eyes (37/44 patients), with hCNV showing the greatest mean visual acuity gain. Mean central retinal thickness in patients with PCV was 523 ± 251 µm, in hCNV 497 ± 171, in RAP lesions 573 ± 132, and in PED 541 ± 158 and decreased to 310 ± 91 µm in PCV, 323 ± 75 µm in hCNV, 357 ± 173 µm in RAP lesions, and 422 ± 150 µm in PED. The mean area of atrophy increased from 2.0 ± 3.6 mm2 at baseline to 4.6 ± 8.6 mm2 at Month 12 (mean difference [95% confidence interval] -0.8 [-8.5 to 7.0], P = 0.8), with the greatest atrophy in patients with PED at Month 12. CONCLUSION All subtypes of neovascular age-related macular degeneration showed anatomical improvement and stabilization of visual function during intravitreal treatment.
