Intravitreal aflibercept 8 mg in neovascular age-related macular degeneration (PULSAR): 48-week results from a randomised, double-masked, non-inferiority, phase 3 trial.

BACKGROUND: Intravitreal aflibercept 8 mg could improve treatment outcomes and provide sustained disease control in patients with neovascular age-related macular degeneration (nAMD), with extended dosing compared with aflibercept 2 mg. METHODS: PULSAR is a phase 3, randomised, three-group, double-masked, non-inferiority, 96-week trial conducted across 223 sites worldwide. Adults with nAMD were randomised 1:1:1 to aflibercept 8 mg every 12 weeks (8q12), aflibercept 8 mg every 16 weeks (8q16), or aflibercept 2 mg every 8 weeks (2q8), following three initial monthly doses in all groups. From week 16, patients in the aflibercept 8 mg groups had their dosing interval shortened if pre-specified dose regimen modification criteria denoting disease activity were met. The primary endpoint was change from baseline in best-corrected visual acuity (BCVA) at week 48. All patients with at least one dose of study treatment were included in the efficacy and safety analyses. This trial is registered with ClinicalTrials.gov (NCT04423718) and is ongoing. FINDINGS: Of 1011 patients randomised to aflibercept 8q12 (n=336), 8q16 (n=338), or 2q8 (n=337) between Aug 11, 2020, and July 30, 2021, 1009 patients received study treatment (aflibercept 8q12 n=335; aflibercept 8q16 n=338; and aflibercept 2q8 n=336). Aflibercept 8q12 and 8q16 showed non-inferior BCVA gains versus aflibercept 2q8 (mean BCVA change from baseline +6·7 [SD 12·6] and +6·2 [11·7] vs +7·6 [12·2] letters). The least squares mean differences between aflibercept 8q12 versus 2q8 and 8q16 versus 2q8, respectively, were -0·97 (95% CI -2·87 to 0·92) and -1·14 (-2·97 to 0·69) letters (non-inferiority margin at 4 letters). The incidence of ocular adverse events in the study eye was similar across groups (aflibercept 8q12 n=129 [39%]; aflibercept 8q16 n=127 [38%]; and aflibercept 2q8 n=130 [39%]). INTERPRETATION: Aflibercept 8 mg showed efficacy and safety with extended dosing intervals, which has the potential to improve the management of patients with nAMD.

Intravitreal aflibercept 8 mg in diabetic macular oedema (PHOTON): 48-week results from a randomised, double-masked, non-inferiority, phase 2/3 trial.

BACKGROUND: A high-dose formulation of intravitreal aflibercept (8 mg) could improve treatment outcomes in diabetic macular oedema (DMO) by requiring fewer injections than the standard comparator, aflibercept 2 mg. We report efficacy and safety results of aflibercept 8 mg versus 2 mg in patients with DMO. METHODS: PHOTON was a randomised, double-masked, non-inferiority, phase 2/3 trial performed at 138 hospitals and specialty retina clinics in seven countries. Eligible patients were adults aged 18 years or older with type 1 or 2 diabetes and centre-involved DMO. Patients were randomly assigned (1:2:1) to intravitreal aflibercept 2 mg every 8 weeks (2q8), aflibercept 8 mg every 12 weeks (8q12), or aflibercept 8 mg every 16 weeks (8q16), following initial monthly dosing. From week 16, dosing intervals for the aflibercept 8 mg groups were shortened if patients met prespecified dose regimen modification criteria denoting disease activity. The primary endpoint was change from baseline in best-corrected visual acuity (BCVA) at week 48 (non-inferiority margin of 4 letters). Efficacy and safety analyses included all randomly assigned patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov (NCT04429503). FINDINGS: Between June 29, 2020, and June 28, 2021, 970 patients were screened for eligibility. After exclusions, 660 patients were enrolled and randomly assigned to receive aflibercept 8q12 (n=329), 8q16 (n=164), or 2q8 (n=167); two patients were randomly assigned in error and did not receive treatment. 658 (99·7%) patients were treated and included in the full analysis set and safety analysis set (8q12 n=328, 8q16 n=163, and 2q8 n=167). Mean patient age was 62·3 years (SD 10·4). 401 (61%) patients were male. 471 (72%) patients were White. Aflibercept 8q12 and 8q16 demonstrated non-inferior BCVA gains to aflibercept 2q8 (BCVA mean change from baseline 8·8 letters [SD 9·0] in the 8q12 group, 7·9 letters [8·4] in the 8q16 group, and 9·2 letters [9·0] in the 2q8 group). The difference in least squares means was -0·57 letters (95% CI -2·26 to 1·13, p value for non-inferiority <0·0001) between 8q12 and 2q8 and -1·44 letters (-3·27 to 0·39, p value for non-inferiority 0·0031) between aflibercept 8q16 and 2q8. Proportions of patients with ocular adverse events in the study eye were similar across groups (8q12 n=104 [32%], 8q16 n=48 [29%], and 2q8 n=46 [28%]). INTERPRETATION: Aflibercept 8 mg demonstrated efficacy and safety with extended dosing intervals and could decrease treatment burden in patients with DMO.

INTRAVITREAL NESVACUMAB (ANTIANGIOPOIETIN 2) PLUS AFLIBERCEPT IN DIABETIC MACULAR EDEMA: Phase 2 RUBY Randomized Trial.

PURPOSE: The purpose of this study was to compare intravitreal nesvacumab (anti-angiopoietin 2) plus aflibercept with intravitreal aflibercept injection (IAI) in diabetic macular edema. METHODS: The eyes (n = 302) were randomized (1:2:3) to nesvacumab 3 mg + aflibercept 2 mg (LD combo), nesvacumab 6 mg + aflibercept 2 mg (HD combo), or IAI 2 mg at baseline, Weeks 4 and 8. LD combo continued every 8 weeks (q8w). HD combo was rerandomized at Week 12 to q8w or every 12 weeks (q12w); IAI to q8w, q12w, or HD combo q8w through Week 32. RESULTS: Week 12 best-corrected visual acuity gains for LD and HD combo versus IAI were 6.8, 8.5, and 8.8 letters; Week 36 changes were similar. Central subfield retinal thickness reductions at Week 12 were -169.4, -184.0, and -174.6 µm (nominal P = 0.0183, HD combo vs. IAI); Week 36 reductions for LD combo and HD combo q8w and q12w versus IAI were -210.4, -223.4, and -193.7 versus -61.9 µm (nominal P < 0.05). At Week 12, 13.3% and 21.3% versus 15.2% had ≥2-step Diabetic Retinopathy Severity Scale improvement (LD and HD combos vs. IAI) and 59.6% and 66.3% versus 53.7% had complete foveal center fluid resolution. Safety was comparable across groups. CONCLUSION: Nesvacumab + aflibercept demonstrated no additional visual benefit over IAI. Anatomic improvements with HD combo may warrant further investigation.

Effect of Intravitreal Aflibercept vs Laser Photocoagulation on Treatment Success of Retinopathy of Prematurity: The FIREFLEYE Randomized Clinical Trial.

Importance: Laser photocoagulation, which is the standard treatment for retinopathy of prematurity (ROP), can have adverse events. Studies of anti-vascular endothelial growth factor injections have suggested efficacy in the treatment of ROP, but few studies have directly compared them with laser treatments. Objective: To compare intravitreal aflibercept vs laser photocoagulation in infants with ROP requiring treatment. Design, Setting, and Participants: This noninferiority, phase 3, 24-week, randomized clinical trial was conducted in 27 countries (64 hospital sites) throughout Asia, Europe, and South America. Overall, 118 infants (gestational age ≤32 weeks at birth or birth weight ≤1500 g) with ROP severity (zone I stage 1+ [stage 1 plus increased disease activity], zone I stage 2+, zone I stage 3, zone I stage 3+, zone II stage 2+, or zone II stage 3+) requiring treatment or with aggressive posterior ROP in at least 1 eye were enrolled between September 25, 2019, and August 28, 2020 (the last visit occurred on February 12, 2021). Interventions: Infants were randomized 2:1 to receive a 0.4-mg dose of intravitreal aflibercept (n = 75) or laser photocoagulation (n = 43) at baseline. Additional treatment was allowed as prespecified. Main Outcomes and Measures: The primary outcome was the proportion of infants without active ROP and unfavorable structural outcomes 24 weeks after starting treatment (assessed by investigators). The requirement for rescue treatment was considered treatment failure. Intravitreal aflibercept was deemed noninferior if the lower limit of the 1-sided 95% bayesian credible interval for the treatment difference was greater than -5%. Results: Among 118 infants randomized, 113 were treated (mean gestational age, 26.3 [SD, 1.9] weeks; 53 [46.9%] were female; 16.8% had aggressive posterior ROP, 19.5% had zone I ROP, and 63.7% had zone II ROP) and 104 completed the study. Treatment (intravitreal aflibercept: n = 75; laser photocoagulation: n = 38) was mostly bilateral (92.9%), and 82.2% of eyes in the intravitreal aflibercept group received 1 injection per eye. Treatment success was 85.5% with intravitreal aflibercept vs 82.1% with laser photocoagulation (between-group difference, 3.4% [1-sided 95% credible interval, -8.0% to ∞]). Rescue treatment was required in 4.8% (95% CI, 1.9% to 9.6%) of eyes in the intravitreal aflibercept group vs 11.1% (95% CI, 4.9% to 20.7%) of eyes in the laser photocoagulation group. The serious adverse event rates were 13.3% (ocular) and 24.0% (systemic) in the intravitreal aflibercept group compared with 7.9% and 36.8%, respectively, in the laser photocoagulation group. Three deaths, which occurred 4 to 9 weeks after intravitreal aflibercept treatment, were considered unrelated to aflibercept by the investigators. Conclusions and Relevance: Among infants with ROP, intravitreal aflibercept compared with laser photocoagulation did not meet criteria for noninferiority with respect to the primary outcome of the proportion of infants achieving treatment success at week 24. Further data would be required for more definitive conclusions regarding the comparative effects of intravitreal aflibercept and laser photocoagulation in this population.

Intravitreal Combined Aflibercept + Anti-Platelet-Derived Growth Factor Receptor ß for Neovascular Age-Related Macular Degeneration: Results of the Phase 2 CAPELLA Trial.

PURPOSE: To compare the efficacy and safety of intravitreal aflibercept + anti-platelet-derived growth factor receptor ß (PDGFRß) combination with intravitreal aflibercept injection (IAI) monotherapy in patients with treatment-naïve neovascular age-related macular degeneration (nAMD). DESIGN: Phase 2, randomized, double-masked study. PARTICIPANTS: A total of 505 patients (eyes) with nAMD. METHODS: Patients were randomized 1:2:2 to low-dose combination intravitreal anti-PDGFRß 1 mg and aflibercept 2 mg (LD combo), high-dose combination intravitreal anti-PDGFRß 3 mg and aflibercept 2 mg (HD combo), or IAI alone every 4 weeks through week 12. At week 12, patients in the HD combo and IAI groups were re-randomized to continue as assigned or switch to HD combo → IAI or IAI → HD combo and dosed every 4 weeks through week 28. During weeks 28 to 52, patients received treatment as needed per prespecified criteria. This report presents efficacy through week 28 and safety through week 52. MAIN OUTCOME MEASURES: Mean best-corrected visual acuity (BCVA) change from baseline at week 12 (primary end point). RESULTS: At week 12, mean BCVA gains from baseline were 5.8, 5.8, and 7.5 letters with LD combo, HD combo, and IAI, respectively (P = 0.21 for LD combo and P = 0.10 for HD combo vs. IAI). The corresponding proportions of eyes that gained ≥15 letters were 12%, 19%, and 22%, respectively. Mean reductions in central retinal thickness from baseline were 126.1, 127.1, and 126.9 µm, respectively. Proportions of eyes with complete resolution of fluid from baseline were 35%, 24%, and 42%, respectively. Vision and anatomic outcomes at week 28 were consistent with the week 12 results. Through week 52, the incidence of intraocular inflammation was 1.0%, 7.5%, 2.1%, 2.1%, and 0%, respectively. The incidence of Anti-Platelet Trialists' Collaboration-defined arterial thromboembolic events was 1.9%, 0.9%, 1.1%, 2.1%, and 1.9%, respectively. CONCLUSIONS: Intravitreal aflibercept + anti-PDGFRß did not improve BCVA over IAI alone. Anatomic outcomes evaluating complete fluid resolution favored IAI. Adverse events were consistent with the reported IAI safety profile, except for a higher frequency of intraocular inflammation in the HD combo group.

Longitudinal Retinal Perfusion Status in Eyes with Diabetic Macular Edema Receiving Intravitreal Aflibercept or Laser in VISTA Study.

PURPOSE: To evaluate changes in retinal perfusion status with intravitreal aflibercept injection (IAI) and laser treatment in the phase 3 VISTA study of patients with diabetic macular edema (DME). DESIGN: Post hoc analysis of a double-masked, randomized, active-controlled, phase 3 trial. PARTICIPANTS: Patients with center-involved DME in the study eye. METHODS: VISTA randomized 466 patients to laser, IAI 2 mg every 4 weeks (2q4), or IAI 2 mg every 8 weeks after 5 monthly doses (2q8). One eye per patient was enrolled in the study. Retinal perfusion status was evaluated by fluorescein angiography based on the presence or absence of retinal nonperfusion (RNP) in quadrants intersecting at the optic nerve head by a masked independent reading center at weeks 24, 52, 72, and 100. Visual and anatomic outcomes were evaluated at all visits. In patients who received rescue treatment, data were censored from the time rescue treatment was given. MAIN OUTCOME MEASURES: Change in perfusion status from baseline through week 100. RESULTS: At week 100, the proportion of eyes with improvement in retinal perfusion (defined as a reduction from baseline in the total number of quadrants in which RNP is present) in the laser control, 2q4, and 2q8 groups was 14.6%, 44.7%, and 40.0%, respectively. The proportion of eyes that experienced worsening in retinal perfusion (defined as an increase from baseline in the total number of quadrants in which RNP is present) at week 100 in the laser control, 2q4, and 2q8 groups was 25.0%, 9.0%, and 8.6%, respectively. CONCLUSION: Post hoc analysis of the phase 3 VISTA study in patients with DME provides evidence that regular IAI dosing not only can slow worsening of retinal perfusion associated with diabetic retinopathy but also may be able to improve retinal perfusion in some cases by decreasing zones of RNP.

Efficacy and Safety of Sarilumab for the Treatment of Posterior Segment Noninfectious Uveitis (SARIL-NIU):: The Phase 2 SATURN Study.

PURPOSE: To assess efficacy and safety of sarilumab, a human anti-interleukin-6 receptor antibody, for treatment of posterior segment noninfectious uveitis (NIU). DESIGN: Randomized, double-masked, placebo-controlled, phase 2 study. PARTICIPANTS: Fifty-eight patients (eyes) with noninfectious intermediate, posterior, or panuveitis. METHODS: Eyes received treatment every 2 weeks for 16 weeks with subcutaneous sarilumab 200 mg or placebo. MAIN OUTCOME MEASURES: The primary end point was the proportion of patients with ≥2-step reduction in vitreous haze (VH) on the Miami scale or with a reduction of systemic corticosteroids (prednisolone or equivalent) to a dose of <10 mg/day at week 16. Primary end point was based on VH evaluation by a central reading center. Investigator evaluation of VH was a prespecified, planned secondary analysis. RESULTS: At week 16, proportion of patients taking sarilumab or placebo with ≥2-step reduction in VH or corticosteroid dose <10 mg/day was 46.1% vs. 30.0% (P = 0.2354) based on central reading center assessment of VH and 64.0% vs. 35.0% (P = 0.0372) based on investigator assessment of VH, respectively. In the subgroup of eyes with VH grade ≥2 at baseline, the mean VH reduction from baseline to week 16 was significantly greater with sarilumab vs. placebo regardless of assessment by the central reading center (-2.1 [n = 11] vs. -1.7 [n = 3], respectively; P = 0.0255) or investigator (-2.5 [n = 19] vs. -1.2 [n = 11], respectively; P = 0.0170). The mean best-corrected visual acuity gain from baseline to week 16 was greater with sarilumab vs. placebo in the overall population (8.9 vs. 3.6 letters, respectively; P = 0.0333) and in the subgroup of eyes with central subfield thickness (CST) ≥300 µm at baseline (12.2 [n = 13] vs. 2.1 [n = 7] letters, respectively; P = 0.0517). Corresponding changes in CST were -46.8 vs. +2.6 µm (P = 0.0683) in the overall population and -112.5 [n = 13] vs. -1.8 [n = 6] µm (P = 0.1317) in the subgroup of eyes with CST ≥300 µm at baseline, respectively. The most common ocular adverse events were worsening of uveitis (0 [placebo] and 3 [sarilumab] patients) and retinal infiltrates (1 [placebo] and 2 [sarilumab] patients). CONCLUSIONS: Subcutaneous sarilumab may provide clinical benefits in the management of NIU of the posterior segment, especially in eyes with uveitic macular edema.

EFFICACY AND SAFETY OUTCOMES OF INTRAVITREAL AFLIBERCEPT FOCUSING ON PATIENTS WITH DIABETIC MACULAR EDEMA FROM JAPAN.

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.

Baseline Factors Affecting Changes in Diabetic Retinopathy Severity Scale Score After Intravitreal Aflibercept or Laser for Diabetic Macular Edema: Post Hoc Analyses from VISTA and VIVID.

PURPOSE: To evaluate whether select baseline systemic and ocular factors influence ≥2-step improvement in the Diabetic Retinopathy Severity Scale (DRSS) score at week 100 in VISTA and VIVID. DESIGN: Post hoc analysis of 2 similarly designed phase 3 trials, VISTA and VIVID. PARTICIPANTS: Total of 456 patients with center-involved diabetic macular edema (DME). METHODS: VISTA and VIVID randomized 872 DME patients to receive intravitreal aflibercept injection (IAI) 2 mg every 4 weeks (2q4), IAI 2 mg every 8 weeks after 5 monthly doses (2q8), or macular laser photocoagulation. This post hoc analysis evaluated the influence of select baseline factors on ≥2-step DRSS score improvement by logistic regression in an integrated VISTA and VIVID dataset using observed cases (n = 456) with patients in each treatment group divided into tertiles based on each characteristic. MAIN OUTCOME MEASURES: Proportion of patients with ≥2-step improvement in DRSS score from baseline at week 100 by age, duration of diabetes, hemoglobin A1c (HbA1c), body mass index (BMI), best-corrected visual acuity (BCVA), central subfield thickness (CST), and DRSS score. RESULTS: At week 100, 10.1%, 34.3%, and 37.6% of patients in the laser, 2q4, and 2q8 groups experienced a ≥2-step DRSS score improvement, respectively. Age, duration of diabetes, HbA1c, BMI, BCVA, and CST had no impact on the ability to achieve ≥2-step improvement in DRSS score. Initial DRSS score was the only factor significantly associated with ≥2-step DRSS score improvement in all treatment groups at weeks 24, 52, 76, and 100. Relatively higher proportions of IAI-treated patients with worse BCVA or thicker CST experienced ≥2-step DRSS score improvement compared with those with better BCVA or thinner CST, respectively, but these associations were not statistically significant. CONCLUSION: A strong association was present between baseline DRSS score and ≥2-step DRSS score improvement at week 100 for DME patients in VISTA and VIVID.

Differential Response to Anti-VEGF Regimens in Age-Related Macular Degeneration Patients with Early Persistent Retinal Fluid.

PURPOSE: To compare the effect of intravitreal aflibercept or ranibizumab drug type and frequency on visual acuity outcomes in eyes with neovascular age-related macular degeneration (NVAMD) and early persistent retinal fluid after 3 initial monthly injections. DESIGN: A post hoc analysis of eyes enrolled in VIEW 1 and VIEW 2, 2 similarly designed, randomized, phase 3 trials. PARTICIPANTS: A total of 1815 eyes with NVAMD from VIEW 1 and VIEW 2. METHODS: Analyses included patients with known fluid status at baseline and weeks 4, 8, and 12 in 3 treatment groups: ranibizumab 0.5 mg every 4 weeks (Rq4) (n = 595), intravitreal aflibercept injection (IAI) 2 mg every 4 weeks (2q4) (n = 613), and IAI 2 mg every 8 weeks (2q8) after 3 monthly injections (n = 607). MAIN OUTCOME MEASURES: Mean best-corrected visual acuity (BCVA) change from baseline over weeks 16 to 52 and the proportion of eyes that gained ≥15 letters or lost ≥5 letters were evaluated in eyes with and without persistent fluid (cystic intraretinal or subretinal fluid at all 4 initial visits). Visual outcomes also were assessed in eyes with persistent fluid by fluid type (intraretinal and subretinal fluid). RESULTS: The proportions of eyes with persistent fluid were 29.4%, 18.8%, and 20.3% in the Rq4, 2q4, and 2q8 groups, respectively. In these eyes, mean BCVA gain from baseline to week 52 was greater with 2q4 compared with Rq4 (P < 0.01) and 2q8 (P < 0.05), whereas it was similar with Rq4 and 2q8 (P = 0.294). At week 52, similar proportions of eyes gained ≥15 letters (31.5%-35.2%), whereas fewer eyes lost ≥5 letters with 2q4 compared with Rq4 and 2q8 (6.5% vs. 16.6% and 16.2%). The pattern of visual outcomes was similar regardless of fluid type. In eyes without persistent fluid, BCVA changes were similar across treatment groups. CONCLUSIONS: In patients with early persistent fluid, 2q4 may provide additional clinical benefit over 2q8 or Rq4.

Intravitreal Aflibercept Injection in Diabetic Macular Edema Patients with and without Prior Anti-Vascular Endothelial Growth Factor Treatment: Outcomes from the Phase 3 Program.

PURPOSE: To evaluate visual and anatomic outcomes after intravitreal aflibercept injection (IAI) versus laser in diabetic macular edema (DME) patients with and without prior anti-vascular endothelial growth factor (VEGF) treatment for DME. DESIGN: Post hoc analysis of eyes from 2 similarly designed, phase 3 trials, VISTA and VIVID. PARTICIPANTS: Patients (eyes) with DME with central involvement from VISTA (n = 461) and VIVID (n = 404). METHODS: Eyes received IAI 2 mg every 4 weeks (2q4), IAI 2 mg every 8 weeks after 5 monthly doses (2q8), or macular laser photocoagulation. MAIN OUTCOME MEASURES: This study reports exploratory outcomes through week 100. Analyses focused on VISTA because more patients received prior anti-VEGF therapy in VISTA (42.9%) versus VIVID (8.9%). RESULTS: Of 42.9% of patients in VISTA who received prior anti-VEGF treatment, 83.3% to 92.6% received ≥ 1 prior injections of bevacizumab, and 71.4% to 82.4% received bevacizumab only as prior anti-VEGF treatment for a duration ranging from 28 days to 3.9 years. In patients with prior anti-VEGF treatment, mean best-corrected visual acuity (BCVA) changes from baseline in the IAI 2q4, IAI 2q8, and laser groups were +10.4 letters, +10.5 letters, and -0.7 letters at week 52 and +10.9 letters, +10.8 letters, and -0.8 letters at week 100, respectively. Corresponding changes in patients without prior anti-VEGF treatment were +14.1 letters, +11.0 letters, and +0.9 letters at week 52 and +12.0 letters, +11.3 letters, and +2.1 letters at week 100. In patients with prior anti-VEGF treatment, mean reductions in central retinal thickness were 180.2 µm, 192.2 µm, and 90.9 µm at week 52 and 180.1 µm, 196.4 µm, and 94.1 µm at week 100. Corresponding reductions in patients without prior anti-VEGF treatment were 190.3 µm, 175.7 µm, and 61.0 µm at week 52 and 200.0 µm, 186.7 µm, and 76.9 µm at week 100. The most frequent serious ocular adverse event was vitreous hemorrhage (1.3%, 0.7%, and 1.9%, respectively). CONCLUSIONS: Visual and anatomic improvements over laser with both IAI regimens were significant and similar through week 100 in subgroups of patients in VISTA with and without prior anti-VEGF treatment for DME.

Comprehensive Review of Ocular and Systemic Safety Events with Intravitreal Aflibercept Injection in Randomized Controlled Trials.

PURPOSE: To assess the ocular and systemic safety of intravitreal aflibercept injection (IAI) compared with controls in IAI trials in neovascular age-related macular degeneration (nAMD), macular edema following central retinal vein occlusion (MEfCRVO), macular edema following branch retinal vein occlusion (MEfBRVO), and diabetic macular edema (DME). DESIGN: Comprehensive review of 10 phase II and III trials of IAI in retinal diseases. PARTICIPANTS: Patients were included from IAI trials in nAMD (CLEAR-IT 2 [52 weeks], VIEW 1 [96 weeks], VIEW 2 [96 weeks], VIEW 1 extension [208 weeks]); MEfCRVO (COPERNICUS [100 weeks], GALILEO [76 weeks]); MEfBRVO (VIBRANT [52 weeks]); and DME (DA VINCI [52 weeks], VIVID [100 weeks], VISTA [100 weeks]). METHODS: Rates were calculated as events/100 person-years at risk (PYR). When applicable, rate ratios (RRs) and 95% confidence intervals (CIs) were provided. MAIN OUTCOME MEASURES: Outcomes included rates for intraocular inflammation, endophthalmitis, serious adverse events (SAEs), wound-healing complications, hypertension (HTN), adjudicated Anti-Platelet Trialists' Collaboration (APTC)-defined arterial thromboembolic events (ATEs) (nonfatal myocardial infarction, nonfatal stroke, and vascular death), and death from all causes. RESULTS: More than 4000 patients contributed >7000 PYR. For all outcomes, there were no meaningful differences between evaluated adverse event rates for IAI and controls. Overall intraocular inflammation rates were 2.37 (control) and 2.06 (IAI); overall RR was 0.87 (95% CI, 0.61-1.27). Overall endophthalmitis rates were 0.52 (control) and 0.22 (IAI); overall RR was 0.42 (95% CI, 0.18-1.03). Overall SAE rates were 23.09 (control) and 20.80 (IAI); overall RR was 0.90 (95% CI, 0.80-1.02). Overall rates of wound-healing complications were 0.17 (control) and 0.15 (IAI); overall RR was 0.85 (95% CI, 0.24-3.86). Overall HTN rates were 14.87 (control) and 11.27 (IAI), with an overall RR of 0.76 (95% CI, 0.65-0.89); HTN rates were highest in MEfBRVO and lowest in nAMD. For adjudicated APTC-defined ATEs, rates were 2.04 (control) and 2.19 (IAI), with an RR of 1.07 (95% CI, 0.73-1.61). Overall death rates were 1.16 (control) and 1.49 (IAI); overall RR was 1.28 (95% CI, 0.80-2.15). CONCLUSIONS: Rates of selected ocular and systemic adverse events with IAI were similar to those of controls and similar across disease states in evaluated IAI trials. Intravitreal aflibercept injection was generally well tolerated in the patients evaluated.

Intravitreal Aflibercept for Macular Edema Following Branch Retinal Vein Occlusion: 52-Week Results of the VIBRANT Study.

PURPOSE: To determine week 52 efficacy and safety outcomes in eyes with macular edema after branch retinal vein occlusion (BRVO) treated with 2 mg intravitreal aflibercept injection (IAI) compared with grid laser. DESIGN: VIBRANT was a double-masked, randomized, phase 3 trial. PARTICIPANTS: Eyes randomized and treated in VIBRANT were followed to week 52. METHODS: In the IAI group, eyes received IAI every 4 weeks through week 24 and IAI every 8 weeks through week 48 with rescue grid laser if needed at week 36. In the grid laser group, all eyes received grid laser at baseline and, if prespecified rescue criteria were met, 1 additional laser from week 12 to 20 and IAI every 8 weeks after 3 monthly doses from week 24 onward (the laser/IAI group). MAIN OUTCOME MEASURES: The primary outcome measure was percentage of eyes with improvement from baseline best-corrected visual acuity (BCVA) letter score ≥15 at week 24. All outcome measures at week 52 were exploratory, and P values are considered nominal. RESULTS: The percentage of eyes with improvement from baseline letter score ≥15 in the IAI and laser/IAI groups was 52.7% versus 26.7% (P = 0.0003) at week 24 and 57.1% versus 41.1% (P = 0.0296) at week 52. The corresponding mean change from baseline BCVA letter score was 17.0 versus 6.9 (P < 0.0001) at week 24 and 17.1 versus 12.2 (P = 0.0035) at week 52. The mean reduction from baseline central retinal thickness was 280.5 µm versus 128.0 µm (P < 0.0001) at week 24 and 283.9 µm versus 249.3 µm (P = 0.0218) at week 52. In the IAI group, 10.6% of eyes received rescue laser at week 36, and in the laser/IAI group, 80.7% received rescue IAI from week 24 to week 48. Traumatic cataract in 1 eye (1.1%) in the IAI group was the only ocular serious adverse event. CONCLUSIONS: After 6 monthly IAI, injections every 8 weeks maintained control of macular edema and visual benefits through week 52. In the laser group, rescue IAI given from week 24 onward resulted in substantial visual improvements at week 52.

Intravitreal Aflibercept for Diabetic Macular Edema: 148-Week Results from the VISTA and VIVID Studies.

PURPOSE: To compare efficacy and safety of intravitreal aflibercept injection (IAI) with macular laser photocoagulation for diabetic macular edema (DME) over 3 years. DESIGN: Two similarly designed phase 3 trials: VISTADME and VIVIDDME. PARTICIPANTS: Patients (eyes; n = 872) with central-involved DME. METHODS: Eyes received IAI 2 mg every 4 weeks (2q4), IAI 2 mg every 8 weeks after 5 monthly doses (2q8), or laser control. From week 24, if rescue treatment criteria were met, IAI patients received active laser, and laser control patients received IAI 2q8. From week 100, laser control patients who had not received IAI rescue treatment received IAI as needed per retreatment criteria. MAIN OUTCOME MEASURES: The primary end point was the change from baseline in best-corrected visual acuity (BCVA) at week 52. We report the 148-week results. RESULTS: Mean BCVA gain from baseline to week 148 with IAI 2q4, IAI 2q8, and laser control was 10.4, 10.5, and 1.4 letters (P < 0.0001) in VISTA and 10.3, 11.7, and 1.6 letters (P < 0.0001) in VIVID, respectively. The proportion of eyes that gained ≥15 letters from baseline at week 148 was 42.9%, 35.8%, and 13.6% (P < 0.0001) in VISTA and 41.2%, 42.2%, and 18.9% (P < 0.0001) in VIVID, respectively. Greater proportions of eyes treated with IAI 2q4 and IAI 2q8 versus those treated with laser control had an improvement of ≥2 steps in the Diabetic Retinopathy Severity Scale (DRSS) score in both VISTA (29.9% and 34.4% vs. 20.1% [P = 0.0350, IAI 2q4; P = 0.0052, IAI 2q8]) and VIVID (44.3% and 47.8% vs. 17.4% [P < 0.0001 for both]). In an integrated safety analysis, the most frequent ocular serious adverse event was cataract (3.1%, 2.1%, 0.3% for 2q4, 2q8, and control). CONCLUSIONS: Visual improvements observed with both IAI regimens (over laser control) at weeks 52 and 100 were maintained at week 148, with similar overall efficacy in the IAI 2q4 and IAI 2q8 groups. Treatment with IAI also had positive effects on the DRSS score. Over 148 weeks, the incidence of adverse events was consistent with the known safety profile of IAI.

Intravitreal Aflibercept Injection in Patients with Myopic Choroidal Neovascularization: The MYRROR Study.

PURPOSE: To evaluate intravitreal aflibercept 2 mg in patients with myopic choroidal neovascularization (CNV). DESIGN: An international, phase III, multicenter, randomized, double-masked, sham-controlled study. PARTICIPANTS: Patients aged ≥ 18 years with high myopia (≤-6.0 diopters or axial length of ≥ 26.5 mm), active myopic CNV, and best-corrected visual acuity (BCVA) of 73-35 Early Treatment Diabetic Retinopathy Study letters in the study eye were included. METHODS: Patients were randomized 3:1 to intravitreal aflibercept or sham. In the intravitreal aflibercept arm, patients received 1 injection at baseline. Additional injections were performed in case of CNV persistence or recurrence at monthly visits through week 44. In the sham arm, patients received sham injections through week 20. At week 24, after assessment of the primary efficacy end point, sham patients received a mandatory intravitreal aflibercept injection followed by intravitreal aflibercept (if disease persisted/recurred) or sham injection every 4 weeks. MAIN OUTCOME MEASURES: Mean change in BCVA from baseline to week 24. RESULTS: A total of 122 patients were randomized to intravitreal aflibercept (n = 91) or sham (n = 31). Baseline demographics were similar across groups. At week 24, patients in the intravitreal aflibercept and sham groups gained 12.1 and lost 2 letters, respectively (P < 0.0001). By week 48, patients in the intravitreal aflibercept and sham/intravitreal aflibercept groups gained 13.5 and 3.9 letters. Patients in the intravitreal aflibercept group received 2 injections (median) in the first study quarter (week 0-8). Median number of injections in quarters 2 to 4 was 0. Patients in the "sham/intravitreal aflibercept" group received 2 and 1 (median) intravitreal aflibercept injections in quarters 3 and 4. Central retinal thickness improved in parallel with visual gains. Incidence of ocular adverse events was similar in both groups through week 48 (37.4% vs. 38.7); most were assessed by investigators as mild. No deaths occurred. CONCLUSIONS: Intravitreal aflibercept 2 mg was effective for treatment of myopic CNV with clinically important visual and anatomic benefits achieved with a limited number of injections given in the first 8 weeks of treatment. No new safety concerns occurred with treatment. Intravitreal aflibercept should be considered as a treatment option for myopic CNV.

Intravitreal aflibercept for macular edema following branch retinal vein occlusion: the 24-week results of the VIBRANT study.

PURPOSE: To compare the efficacy and safety of intravitreal aflibercept injection (IAI) with macular grid laser photocoagulation for the treatment of macular edema after branch retinal vein occlusion (BRVO). DESIGN: The VIBRANT study was a double-masked, active-controlled, randomized, phase III trial. PARTICIPANTS: Treatment-naïve eyes with macular edema after BRVO were included in the study if the occlusion occurred within 12 months and best-corrected visual acuity (BCVA) was between ≤73 and ≥24 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (20/40-20/320 Snellen equivalent). METHODS: Eyes (1 eye per patient) received either IAI 2 mg every 4 weeks (n=91) from baseline to week 20 or grid laser (n=92) at baseline with a single grid laser rescue treatment, if needed, from weeks 12 through 20. MAIN OUTCOME MEASURES: The primary outcome measure was the proportion of eyes that gained ≥15 ETDRS letters from baseline BCVA at week 24. Secondary end points included mean change from baseline BCVA and central retinal thickness (CRT) at week 24. RESULTS: The proportion of eyes that gained ≥15 ETDRS letters from baseline at week 24 was 52.7% in the IAI group compared with 26.7% in the laser group (P=0.0003). The mean improvement from baseline BCVA at week 24 was 17.0 ETDRS letters in the IAI group and 6.9 ETDRS letters in the laser group (P<0.0001). The mean reduction in CRT from baseline at week 24 was 280.5 µm in the IAI group and 128.0 µm in the laser group (P<0.0001). Traumatic cataract in an IAI patient was the only ocular serious adverse event (SAE) that occurred. There were no cases of intraocular inflammation or endophthalmitis. The incidence of nonocular SAEs was 8.8% in the IAI group and 9.8% in the laser group. One Anti-Platelet Trialists' Collaboration-defined event of nonfatal stroke (1.1%) and 1 death (1.1%) due to pneumonia occurred during the 24 weeks of the study, both in patients in the laser group. CONCLUSIONS: Monthly IAI provided significantly greater visual benefit and reduction in CRT at 24 weeks than grid laser photocoagulation in eyes with macular edema after BRVO.

Intravitreal Aflibercept for Diabetic Macular Edema: 100-Week Results From the VISTA and VIVID Studies.

PURPOSE: To compare efficacy and safety of 2 dosing regimens of intravitreal aflibercept injection (IAI) with macular laser photocoagulation for diabetic macular edema (DME). DESIGN: Two similarly designed, randomized, phase 3 trials, VISTA(DME) and VIVID(DME). PARTICIPANTS: Patients (eyes; n=872) with type 1 or 2 diabetes mellitus who had DME with central involvement. METHODS: Eyes received IAI 2 mg every 4 weeks (2q4), IAI 2 mg every 8 weeks after 5 monthly doses (2q8), or laser control. MAIN OUTCOME MEASURES: The primary end point was mean change from baseline in best-corrected visual acuity (BCVA) at week 52. This report presents the 100-week results including mean change from baseline in BCVA, proportion of eyes that gained ≥15 letters, and proportion of eyes with a ≥2-step improvement in the Diabetic Retinopathy Severity Scale (DRSS) score. RESULTS: Mean BCVA gain from baseline to week 100 with IAI 2q4, IAI 2q8, and laser control was 11.5, 11.1, and 0.9 letters (P < 0.0001) in VISTA and 11.4, 9.4, and 0.7 letters (P < 0.0001) in VIVID, respectively. The proportion of eyes that gained ≥15 letters from baseline at week 100 was 38.3%, 33.1%, and 13.0% (P < 0.0001) in VISTA and 38.2%, 31.1%, and 12.1% (P ≤ 0.0001) in VIVID. The proportion of eyes that lost ≥15 letters at week 100 was 3.2%, 0.7%, and 9.7% (P ≤ 0.0220) in VISTA and 2.2%, 1.5%, and 12.9% (P ≤ 0.0008) in VIVID. Significantly more eyes in the IAI 2q4 and 2q8 groups versus those in the laser control group had a ≥2 step improvement in the DRSS score in both VISTA (37.0% and 37.1% vs. 15.6%; P < 0.0001) and VIVID (29.3% and 32.6% vs. 8.2%; P ≤ 0.0004). In an integrated safety analysis, the most frequent serious ocular adverse event was cataract (2.4%, 1.0%, and 0.3% for 2q4, 2q8, and control). CONCLUSIONS: In both VISTA and VIVID, the 52-week visual and anatomic superiority of IAI over laser control was sustained through week 100, with similar efficacy in the 2q4 and 2q8 groups. Safety in these studies was consistent with the known safety profile of IAI.

Microperimetric assessment of retinal sensitivity in eyes with diabetic macular edema from a phase 2 study of intravitreal aflibercept.

PURPOSE: To evaluate retinal sensitivity in patients with diabetic macular edema who received intravitreal aflibercept injection (IAI) or laser. METHODS: A substudy included 46 patients from DA VINCI (a randomized, double-masked Phase 2 study) receiving either laser, 0.5 mg IAI every 4 weeks, 2 mg IAI every 4 weeks, 2 mg IAI every 8 weeks after 3 monthly doses (2q8), or 2 mg IAI as-needed after 3 monthly doses for 52 weeks. Retinal sensitivity was measured in one (central), five (one central and four inner), and eight (four inner and four outer) optical coherence tomography subfields. RESULTS: Mean best-corrected visual acuity improvement in the subgroup at Week 52 was 3.3 letters with laser and ranged from 5.4 to 16.3 letters in the IAI groups. Retinal sensitivity of laser patients at Week 52 was comparable with baseline in the central optical coherence tomography subfield but decreased in the five and eight optical coherence tomography subfields. Compared with laser, retinal sensitivity significantly increased with IAI in the 2q8 and pooled IAI groups in the 5 and 8 optical coherence tomography subfields at Week 52 (P < 0.05). CONCLUSION: Intravitreal aflibercept injection improved best-corrected visual acuity and retinal sensitivity in this subgroup of patients. Laser may cause a deterioration of macular function that is not detectable with best-corrected visual acuity testing.
