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
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
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.

Ophthalmology. Retina. 2021;(1):60-70
Abstract
PURPOSE This study evaluated the potential safety, efficacy, and durability advantages of investigational triamcinolone acetonide suspension (CLS-TA; Clearside Biomedical, Alpharetta, GA) administered suprachoroidally in conjunction with intravitreal aflibercept compared with aflibercept monotherapy for treatment of diabetic macular edema (DME). DESIGN TYBEE was a prospective, controlled, double-masked study. Patients were randomized 1:1 to CLS-TA and aflibercept (active) or aflibercept monotherapy (control), and assessed over 24 weeks. PARTICIPANTS Treatment-naive DME patients with best-corrected visual acuity (BCVA) of 20 to 70 letters and central subfield retinal thickness (CST) of more than 300 μm. METHODS Patients in the active group (n = 36) received CLS-TA and aflibercept at baseline and week 12. Patients in the control group (n = 35) received aflibercept at baseline, week 4, week 8, and week 12. To mask both groups, sham suprachoroidal and intravitreal injections were utilized. All patients were eligible to receive aflibercept as needed at weeks 4, 8, 16, and 20 per prespecified criteria. MAIN OUTCOME MEASURE Mean change in BCVA from baseline. Treatment differences were assessed with a 2-sided significance level of 0.10. RESULTS Mean BCVA changes from baseline to week 24 were not statistically different in the active and control groups (intention-to-treat [ITT] population: +11.4 letters and +13.8 letters [P = 0.288]; per protocol [PP] population: +12.3 letters and +13.5 letters [P = 0.664]; respectively). Greater improvement in CST was seen in the active versus control group (ITT population: -212.1 μm and -178.6 μm [P = 0.089]; PP population: -226.5 μm and -176.1 μm [P = 0.035]; respectively). Compared with the control group, eyes in the active group received fewer treatments (scheduled plus as-needed treatments averaging 4.6 versus 2.6, respectively). No treatment-related serious adverse events were observed. Ocular adverse events were low for both arms. Cataract events, all assessed as unrelated to treatment, and events of elevated intraocular pressure trended higher in the active group. CONCLUSIONS CLS-TA administered suprachoroidally in conjunction with intravitreal aflibercept for treatment of DME provides simliar visual benefit at 24 weeks' follow-up compared with aflibercept monotherapy, is well tolerated and shows modest anatomic benefit with potential to reduce treatment burden.

Abstract
PURPOSE To evaluate whether baseline demographic, clinical, and OCT characteristics predict visual acuity (VA) outcomes in patients receiving anti-vascular endothelial growth factor (VEGF) therapy for macular edema (ME) due to central retinal vein occlusion (CRVO). DESIGN Post hoc analysis of the randomized noninferiority trial (Lucentis, Eylea, Avastin in CRVO) LEAVO Study from December 12, 2014, to December 16, 2016, carried out across 44 UK National Health Service ophthalmology departments. PARTICIPANTS Data on 267 participants with a baseline best-corrected mean visual acuity (BCVA) range of 19 to 78 Early Treatment Diabetic Retinopathy Study letter score (approximate Snellen equivalent, 20/32 to 20/320) who had central subfield thickness (CST) ≥ 320 μm on Spectralis OCT (Heidelberg Engineering) were analyzed. METHODS Study participants were randomized to receive repeated intravitreal injections of ranibizumab (0.5 mg/50 μl), aflibercept (2.0 mg/50 μl), or bevacizumab (1.25 mg/50 μl), and a protocol-driven pro re nata re-treatment regimen at 4 to 8 weekly visits was followed up to week 100 after 4 mandated 4-weekly loading injections. MAIN OUTCOME MEASURES Change in BCVA and percentage of patients gaining ≥ 10 letters and achieving BCVA letter score > 70 letters at 52 and 100 weeks. RESULTS The analysis was adjusted for treatment effects and confirmed by sensitivity analysis. Age ≥ 75 years is a poor predictor for all 3 visual outcomes. Lower baseline BCVA predicted 10-letter gainers and higher gains in BCVA, although it is a poor predictor of achieving > 70 Early Treatment Diabetic Retinopathy Study letters. None of the baseline OCT morphologic characteristics except ellipsoid zone (EZ) integrity influenced any visual outcomes. Both baseline CST and total macular volume showed a nonlinear relation to 10-letter gainers, with CST > 900 μm being a poor prognostic indicator. Baseline CST and macular volume did not predict mean change in BCVA or BCVA > 70 letters at 52 and 100 weeks. The sensitivity analysis conclusions after removing iCRVO were similar. CONCLUSIONS At presentation, younger age, higher baseline BCVA, and a definitely intact subfoveal EZ are predictors of BCVA score > 70 letters at 100 weeks.

Abstract
BACKGROUND/PURPOSE Treating neovascular age-related macular degeneration with intravitreal aflibercept treat-and-extend (T&E) can reduce treatment burden. ARIES assessed whether intravitreal aflibercept early-start T&E was noninferior to late-start T&E. METHODS A randomized, open-label, Phase 3b/4 study that included treatment-naïve patients aged ≥50 years with the best-corrected visual acuity 73-25 Early Treatment Diabetic Retinopathy Study letters and active choroidal neovascularization secondary to AMD. Patients received 2 mg intravitreal aflibercept at Week (W) 0, W4, W8, and W16. At W16, patients were randomized 1:1 to early-start (2W interval adjustments) or late-start T&E (8W intervals until W48 then 2W interval adjustments). Primary endpoint: the best-corrected visual acuity change from randomization to W104. RESULTS Two-hundred seventy-one patients were randomized. The mean (SD) best-corrected visual acuity at baseline was 60.2 (12.1; early-T&E) and 61.3 (10.8; late-T&E) letters. The mean (SD) best-corrected visual acuity change (W16-104) was -2.1 (11.4) versus -0.4 (8.4) letters (early-T&E vs. late-T&E; least-squares mean difference: -2.0; 95% confidence interval: -4.75 to 0.71; P = 0.0162 for noninferior); +4.3 (13.4) versus +7.9 (11.9) letters (W0-104). The mean (SD) number of injections was 12.0 (2.3) versus 13.0 (1.8). From baseline to W104, 93.4% and 96.2% maintained best-corrected visual acuity; the mean (SD) central retinal thickness change was -161.6 (135.6) µm and -158.6 (125.1) µm. The last injection interval (W104) was ≥12W for 47.2% and 51.9% of patients. CONCLUSION Outcomes were similar between patients with neovascular age-related macular degeneration treated with an intravitreal aflibercept early-T&E or late-T&E regimen after initial dosing, with one injection difference over 2 years.

Abstract
INTRODUCTION The purpose of this study was to report the one-year results of treatment of diabetic macular edema (DME) with aflibercept using a treat-and-extend regimen (TER). METHODS This was a prospective, multicenter, single-arm study planned for 2 years. The eyes received 5 consecutive intravitreal injections of 2 mg of aflibercept every 4 weeks, and the interval between injections was then adjusted by 2 weeks based on changes in the central subfield macular thickness (CSMT). If the CSMT was worse, stable, or better, the interval was shortened, extended, or maintained, respectively. The primary outcome measure was the change in best-corrected visual acuity (BCVA) from baseline to 104 weeks, and the secondary outcome was the change in BCVA from baseline to 52 weeks. RESULTS Of the 48 patients enrolled, 46 completed a 1-year visit. BCVA improved significantly by 9.1 letters (95% confidence interval: 5.3-13.0 letters) from 56.2 letters at baseline (p < 0.001), and CSMT decreased by -171.7 μm from 489.4 to 317.7 μm (p < 0.001). The proportion of eyes having 20/40 or better vision increased from 17.4 to 41.3%, and the proportion of eyes that gained ≥15 letters was 28.3%. The mean number of injections was 8.5 times for 52 weeks. Worsening of macular edema did not occur in 76.1% of eyes during the extension period, and the interval between injections was extended to 12 weeks in 73.9% of eyes at 52 weeks. CONCLUSIONS The TER showed 1-year efficacy comparable to that of the fixed dosing regimen of pivotal trials, and its flexible dosing would prevent overtreatment.

Abstract
BACKGROUND Cardiovascular outcome trials have suggested that glucagon-like peptide 1 (GLP-1) receptor agonists might reduce strokes. We analysed the effect of dulaglutide on stroke within the researching cardiovascular events with a weekly incretin in diabetes (REWIND) trial. METHODS REWIND was a multicentre, randomised, double-blind, placebo-controlled trial done at 371 sites in 24 countries. Men and women (aged ≥50 years) with established or newly detected type 2 diabetes whose HbA1c was 9·5% or less (with no lower limit) on stable doses of up to two oral glucose-lowering drugs with or without basal insulin therapy were eligible if their body-mass index was at least 23 kg/m2. Participants were randomly assigned (1:1) to weekly subcutaneous injections of either masked dulaglutide 1·5 mg or the same volume of masked placebo (containing the same excipients but without dulaglutide). Randomisation was done by a computer-generated random code with an interactive web response system with stratification by site. Participants, investigators, the trial leadership, and all other personnel were masked to treatment allocation until the trial was completed and the database was locked. During the treatment period, participants in both groups were instructed to inject study drug on the same day at around the same time, each week. Strokes were categorised as fatal or non-fatal, and as either ischaemic, haemorrhagic, or undetermined. Stroke severity was assessed using the modified Rankin scale. Participants were seen at 2 weeks, 3 months, 6 months, and then every 3 months for drug dispensing and every 6 months for detailed assessments, until 1200 confirmed primary outcomes accrued. The primary endpoint was the first occurrence of any component of the composite outcome, which comprised non-fatal myocardial infarction, non-fatal stroke, or death from cardiovascular or unknown causes. All analyses were done according to an intention-to-treat strategy that included all randomly assigned participants, irrespective of adherence. The trial is registered with ClinicalTrials.gov, number NCT01394952. FINDINGS Between Aug 18, 2011, and Aug 14, 2013, we screened 12 133 patients, of whom 9901 with type 2 diabetes and additional cardiovascular risk factors were randomly assigned to either dulaglutide (n=4949) or an equal volume of placebo (n=4952). During a median follow-up of 5·4 years, cerebrovascular and other cardiovascular outcomes were ascertained and adjudicated. 158 (3·2%) of 4949 participants assigned to dulaglutide and 205 (4·1%) of 4952 participants assigned to placebo had a stroke during follow-up (hazard ratio [HR] 0·76, 95% CI 0·62-0·94; p=0·010). Dulaglutide reduced ischaemic stroke (0·75, 0·59-0·94, p=0·012) but had no effect on haemorrhagic stroke (1·05, 0·55-1·99; p=0·89). Dulaglutide also reduced the composite of non-fatal stroke or all-cause death (0·88, 0·79-0·98; p=0·017) and disabling stroke (0·74, 0·56-0·99; p=0·042). The degree of disability after stroke did not differ by treatment group. INTERPRETATION Long-term dulaglutide use might reduce clinically relevant ischaemic stroke in people with type 2 diabetes but does not affect stroke severity. FUNDING Eli Lilly and Company.
