Pharmacotherapeutic group: Ophthalmologicals/Antineovascularisation agents, ATC code: S01LA05
Aflibercept is a recombinant fusion protein consisting of portions of human VEGF receptor 1 and 2extracellular domains fused to the Fc portion of human IgG1.
Aflibercept is produced in Chinese hamster ovary (CHO) K1 cells by recombinant DNA technology.
Mechanism of actionVascular endothelial growth factor-A (VEGF-A) and placental growth factor (PlGF) are members ofthe VEGF family of angiogenic factors that can act as potent mitogenic, chemotactic, and vascularpermeability factors for endothelial cells. VEGF acts via two receptor tyrosine kinases, VEGFR-1 and
VEGFR-2, present on the surface of endothelial cells. PlGF binds only to VEGFR-1, which is alsopresent on the surface of leucocytes. Excessive activation of these receptors by VEGF-A can result inpathological neovascularisation and excessive vascular permeability. PlGF can act independently toactivate the VEGFR-1 to promote an inflammatory response within the retina, and is known toincrease in pathological states such as nAMD, diabetic retinopathy (DR), DME, and retinal veinocclusion (RVO).
Pharmacodynamic effectsAflibercept acts as a soluble decoy receptor that binds VEGF-A and PlGF with higher affinity thantheir natural receptors, and thereby can inhibit the binding and activation of these cognate VEGFreceptors.
In animal studies, aflibercept can prevent pathological neovascularization and vascular leakage in anumber of different models of ocular disease.
nAMDnAMD is characterised by pathological choroidal neovascularisation (CNV). Leakage of blood andfluid from CNV may cause retinal oedema and/or sub-/intra-retinal haemorrhage, resulting in loss ofvisual acuity.
The pharmacodynamic effects of aflibercept 114.3 mg/ml administered every 12 (8Q12) and every 16(8Q16) weeks are described in comparison with aflibercept 40 mg/ml administered every 8 weeks(2Q8) for the nAMD indication. These effects are shown as the change in CNV size from baseline toweek 12; change in total lesion area from baseline to weeks 48, 60, and 96; and change from baselinein central retinal thickness (CRT).
In the pooled group of patients treated with 8Q12 or 8Q16, reductions in CNV size (LS mean, basedon a mixed model for repeated measurements [MMRM]) at week 12 were -1.63 mm2 comparedto -1.17 mm2 for patients treated with 2Q8.
Pharmacodynamic effects were generally maintained through week 156.

Clinical efficacy and safetynAMD
Study objectives
The safety and efficacy of Eylea 114.3 mg/ml were assessed in a randomised, multi-centre,double-masked, active-controlled study (PULSAR) in patients with treatment naïve nAMD.
The primary objective was to determine if treatment with Eylea 114.3 mg/ml at intervals of 12 (8Q12)or 16 weeks (8Q16) provides non-inferior best corrected visual acuity (BCVA) change compared to
Eylea 40 mg/ml every 8 weeks in patients with nAMD.
The secondary objectives were to determine the effect of Eylea 114.3 mg/ml versus Eylea 40 mg/mlon anatomic and other visual measures of response, and to evaluate the safety, immunogenicity, andpharmacokinetics of aflibercept.
The primary efficacy endpoint was the change from baseline in BCVA measured by the earlytreatment diabetic retinopathy study (ETDRS) letter score at week 48.
The key secondary endpoints were the change in BCVA from baseline at week 60 and the proportionof patients with no intraretinal fluid (IRF) and no subretinal fluid (SRF) in central subfield at week 16.
Further secondary endpoints were the proportion of patients gaining at least 15 letters in BCVA frombaseline at week 48, the proportion of patients achieving an ETDRS letter score of at least 69(approximate 20/40 Snellen equivalent) at week 48, and the change from baseline in National Eye
Institute Visual Functioning Questionnaire-25 (NEI-VFQ-25) total score at week 48, among others.
LS mean change in CRT (microns)
In the PULSAR study a total of 1 009 patients were treated. The patients were assigned in a 1:1:1 ratioto 1 of 3 parallel treatment groups:
1. Eylea 114.3 mg/ml administered every 12 weeks (8Q12)2. Eylea 114.3 mg/ml administered every 16 weeks (8Q16)3. Eylea 40 mg/ml administered every 8 weeks (2Q8)
All patients received 3 initial injections of the assigned dose at 4-week intervals.
Per study protocol the interval of the 8Q12- and 8Q16-groups was to be shortened if both of thefollowing criteria were met:
1. >5 letters loss in BCVA from week 12, and2. >25 microns increase in CRT from week 12 or new foveal haemorrhage or new fovealneovascularisation.
Regardless of whether patient intervals were maintained or shortened in year 1, per study protocol allpatients in the 8Q12- and 8Q16-groups were eligible for interval extension (by 4 weeks increments),beginning at week 52, if the following criteria were met:
1. <5 letters loss in BCVA from week 12, and2. no fluid in the central subfield on optical coherence tomography (OCT), and3. no new onset of foveal haemorrhage or foveal neovascularisation.
For patients who did not meet the criteria for shortening or extension of the interval, the dosinginterval was maintained. The minimum interval between injections was 8 weeks in all groups.
Patients with bilateral disease were eligible to receive Eylea 40 mg/ml treatment or another anti-VEGFmedicinal product in their fellow eye.
Patient characteristics at baseline
Patient ages ranged from 50 to 96 years with a mean of 74.5 years.
Approximately 92% (309/335) and 87% (295/338) of the patients randomised to the 8Q12- and8Q16-groups, respectively, were 65 years of age or older and approximately 51% (172/335) and 51%(171/338) were 75 years of age or older.
ResultsPatients in the 8Q12-, 8Q16- and 2Q8-groups who completed week 48 received a median (mean) of6.0 (6.1), 5.0 (5.2) and 7.0 (6.9) injections, respectively.
At week 48, in the 8Q12-group, 79.4% of patients maintained Q12 intervals while in the 8Q16-group76.6% of patients maintained Q16 intervals.
Patients in the 8Q12-, 8Q16- and 2Q8-groups who completed week 60 received a median (mean) of7.0 (7.1), 6.0 (6.2) and 9.0 (8.8) injections, respectively.
At week 60, 43.1% of patients in the 8Q12-group were extended to a treatment interval of 16 weeks,and 38.5% of patients in the 8Q16-group were extended to a treatment interval of 20 weeks.
Patients in the 8Q12-, 8Q16- and 2Q8-groups who completed week 96 received a median (mean) of9.0 (9.7), 8.0 (8.2) and 13.0 (12.8) injections, respectively.
At week 96, in the pooled 8Q12- and 8Q16-groups 71.0% of patients had attained treatment intervalsof ≥16 weeks, 46.8% of patients had attained treatment intervals of ≥20 weeks, and 27.8% of patientshad attained treatment intervals of 24 weeks, while maintaining visual and anatomic outcomes.
Treatment with 8Q12 and 8Q16 was shown to be non-inferior and clinically equivalent to treatmentwith 2Q8 in terms of the primary efficacy endpoint ‘mean change in BCVA at week 48’ and the keysecondary efficacy endpoint ‘mean change in BCVA at week 60’. The treatment effect with
Eylea 114.3 mg/ml in mean change in BCVA was maintained through week 96.
Furthermore, treatment with Eylea (pooled 8Q12- and 8Q16-groups) was shown to be superior totreatment with 2Q8 in terms of the key secondary efficacy endpoint ‘proportion of patients with nointraretinal fluid (IRF) and no subretinal fluid (SRF) in the central subfield at week 16’ (see table 4).

Results - PULSAR extension phase
At the end of the main phase of the study at week 96, patients could enrol into the 60 week, open-labelextension phase. 417 patients originally assigned to 8Q12 and 8Q16 continued on Eylea 114.3 mg/mlwhile maintaining their latest intervals. 208 patients originally assigned to 2Q8 at the beginning of thestudy were switched to Eylea 114.3 mg/ml starting at 12-week intervals. Treatment intervals could befurther adjusted based on the physician’s judgement of visual and/or anatomic outcomes.
In those patients originally assigned to 8Q12 and 8Q16, the treatment effect with Eylea 114.3 mg/mlwas generally maintained throughout 3 years (week 156). The LS mean change from baseline in thepooled 8Q12- and 8Q16-groups in BCVA was +3.41 letters and in CRT was -148.05 microns atweek 156.
In those patients originally assigned to 2Q8, the treatment effect with Eylea 114.3 mg/ml was similar.
The LS mean change from baseline in BCVA was +4.58 letters and in CRT was -145.21 microns atweek 156.
Patients in the 8Q12- and 8Q16-groups who completed week 156 received a median (mean) of 13.0(13.5) and 11.0 (12.2) injections, respectively.
Patients who switched to Eylea 114.3 mg/ml and completed week 156 received a total median (mean)of 18.0 (17.7) injections, of which 5.0 (4.9) injections were administered after the switch to
Eylea 114.3 mg/ml within the 60 weeks of the study extension phase.
The overall safety profile in the extension phase was similar to that observed in the main phase.

DMEStudy objectives
The safety and efficacy of Eylea 114.3 mg/ml were assessed in a randomised, multi-centre,double-masked, active-controlled study (PHOTON) in patients with DME.
The primary objective was to determine if treatment with Eylea 114.3 mg/ml at intervals of 12 (8Q12)or 16 weeks (8Q16) provides non-inferior BCVA change compared to Eylea 40 mg/ml every 8 weeks.
The secondary objectives were to determine the effect of Eylea 114.3 mg/ml versus Eylea 40 mg/mlon anatomic and other visual measures of response, and to evaluate the safety, immunogenicity, andpharmacokinetics of aflibercept.
The primary efficacy endpoint was the change from baseline in BCVA measured by the earlytreatment diabetic retinopathy study (ETDRS) letter score at week 48.
One key secondary endpoint was the change in BCVA from baseline at week 60.
Further secondary endpoints were the proportion of patients gaining at least 15 letters in BCVA frombaseline at week 48, the proportion of patients achieving an ETDRS letter score of at least 69(approximate 20/40 Snellen equivalent) at week 48, and the change from baseline in National Eye
Institute Visual Functioning Questionnaire-25 (NEI-VFQ-25) total score at week 48, among others.
In the PHOTON study a total of 658 patients were treated. The patients were assigned in a 2:1:1 ratioto 1 of 3 parallel treatment groups:
1. Eylea 114.3 mg/ml administered every 12 weeks (8Q12)2. Eylea 114.3 mg/ml administered every 16 weeks (8Q16)3. Eylea 40 mg/ml administered every 8 weeks (2Q8)
Patients who were switched from other anti-VEGF medicinal products to Eylea 114.3 mg/ml receivedthe last injection of the previous treatment at least 12 weeks prior to initiating the Eylea 114.3 mg/mltreatment.
All patients in the 8Q12- and 8Q16-groups received 3 initial injections and all patients in the2Q8-group received 5 initial injections at 4-week intervals.
Per study protocol the interval of the 8Q12- and 8Q16-groups was to be shortened if both of thefollowing criteria were met:
1. >10 letter loss in BCVA from week 12 in association with persistent or worsening DME, and2. >50 microns increase in CRT from week 12.
Regardless of whether patient intervals were maintained or shortened in year 1, per study protocol allpatients in the 8Q12- and 8Q16-groups were eligible for interval extension (by 4 weeks increments),beginning at week 52, if the following criteria were met:
1. <5 letter loss in BCVA from week 12, and2. CRT <300 microns on SD-OCT (or <320 microns if measured including RPE).
For patients who did not meet the criteria for shortening or extension of the interval, the dosinginterval was maintained. The minimum interval between injections was 8 weeks in all groups.
Patients with bilateral disease were eligible to receive Eylea 40 mg/ml treatment in their fellow eye.
Patient characteristics at baseline
Patient ages ranged from 24 to 90 years with a mean of 62.3 years.
Approximately 44% (143/328) and 44% (71/163) of the patients randomised to the 8Q12- and8Q16-groups, respectively, were 65 years of age or older and approximately 11% (36/328) and 14%(14/163) were 75 years of age or older.
The proportion of patients who were treated previously for DME was balanced between the treatmentgroups (43.6% in 8Q12-, 43.6% in 8Q16-, 44.3% in 2Q8-group).
ResultsPatients in the 8Q12-, 8Q16- and 2Q8-groups who completed week 48 received a median (mean) of6.0 (6.0), 5.0 (5.0) and 8.0 (7.9) injections, respectively.
At week 48, in the 8Q12-group, 91.0% of patients maintained Q12 intervals while in the 8Q16-group89.1% of patients maintained Q16 intervals.
Patients in the 8Q12-, 8Q16- and 2Q8-groups who completed week 60 received a median (mean) of7.0 (7.0), 6.0 (6.0) and 10.0 (9.8) injections, respectively. At week 60, 42.6% of patients in the8Q12-group were extended to a treatment interval of 16 weeks, and 34.2% of patients in the8Q16-group were extended to a treatment interval of 20 weeks.
Patients in the 8Q12-, 8Q16- and 2Q8-groups who completed week 96 received a median (mean) of9.0 (9.5), 8.0 (7.8) and 14.0 (13.8) injections, respectively.
At week 96, in the pooled 8Q12- and 8Q16-groups 72.4% of patients had attained treatment intervalsof ≥16 weeks, 44.3% of patients had attained treatment intervals of ≥20 weeks, and 26.8% of patientshad attained treatment intervals of 24 weeks, while maintaining visual and anatomic outcomes.
Treatment with Eylea (both 8Q12- and 8Q16-groups) was shown to be non-inferior and clinicallyequivalent to treatment with 2Q8 in terms of the primary efficacy endpoint ‘mean change in BCVA atweek 48’ and the key secondary efficacy endpoint ‘mean change in BCVA at week 60’. The treatmenteffect with Eylea 114.3 mg/ml in mean change in BCVA was maintained through week 96.

LS mean change visual acuity(letters)
Eylea at all doses (8Q12, 8Q16, 2Q8) demonstrated meaningful increase from baseline in thepre-specified secondary efficacy endpoint national eye institute visual function questionnaire (NEI
VFQ-25).
No clinically meaningful differences were found between the 8Q12-, 8Q16- and 2Q8-groups inchanges of NEI VFQ-25 total score at week 48 and week 96 from baseline.
Efficacy results in evaluable subgroups for age, gender, geographic region, ethnicity, race, baseline
BCVA and baseline CRT and prior DME treatment were consistent with the results in the overallpopulation.
Efficacy was generally maintained through week 96.
Treatment effects in the sub-group of previously treated patients were similar to those seen in patientswho were treatment naïve.
Results - PHOTON extension phase
At the end of the main phase of the study at week 96, patients could enrol into the 60 week, open-labelextension phase. 195 patients originally assigned to 8Q12 and 8Q16 continued on Eylea 114.3 mg/mlwhile maintaining their latest intervals. 70 patients originally assigned to 2Q8 at the beginning of thestudy were switched to Eylea 114.3 mg/ml starting at 12-week intervals. Treatment intervals could befurther adjusted based on the physician’s judgement of visual and/or anatomic outcomes.
In those patients originally assigned to 8Q12 and 8Q16, the treatment effect with Eylea 114.3 mg/mlwas generally maintained throughout 3 years (week 156). The LS mean change from baseline in thepooled 8Q12- and 8Q16-groups in BCVA was +7.2 letters and in CRT was -192.4 microns atweek 156.
In those patients originally assigned to 2Q8, the treatment effect with Eylea 114.3 mg/ml was similar.
The LS mean change from baseline in BCVA was +6.5 letters and in CRT was -197.4 microns atweek 156.
Patients in the 8Q12- and 8Q16-groups who completed week 156 received a median (mean) of 13.0(13.2) and 11.0 (11.4) injections, respectively.
Patients who switched to Eylea 114.3 mg/ml and completed week 156 received a total median (mean)of 19.0 (18.6) injections, of which 5.0 (4.8) injections were administered after the switch to
Eylea 114.3 mg/ml within the 60 weeks of the study extension phase.
The overall safety profile in the extension phase was similar to that observed in the main phase.
