`Preparation for Administration
`2.5
`EYLEA should be inspected visually prior to administration. If particulates, cloudiness, or
`discoloration are visible, the vial must not be used.
`
`Using aseptic technique, the intravitreal injection should be performed with a 30-gauge x ½-inch
`injection needle.
`
`Vial
`
`The glass vial is for single use only.
`
`1. Remove the protective plastic cap from the vial (see Figure 1).
`
`Figure 1:
`
`2. Clean the top of the vial with an alcohol wipe (see Figure 2).

`3. Remove the 19-gauge x 1½-inch, 5-micron, filter needle from its pouch and remove the
`1-mL syringe supplied in the carton from its pouch. Attach the filter needle to the syringe by
`twisting it onto the Luer lock syringe tip (see Figure 3).
`
`Figure 3:
`
`4. Push the filter needle into the center of the vial stopper until the needle is completely inserted
`into the vial and the tip touches the bottom or bottom edge of the vial.
`5. Using aseptic technique withdraw all of the EYLEA vial contents into the syringe, keeping
`the vial in an upright position, slightly inclined to ease complete withdrawal. To deter the
`introduction of air, ensure the bevel of the filter needle is submerged into the liquid. Continue
`to tilt the vial during withdrawal keeping the bevel of the filter needle submerged in the
`liquid (see Figures 4a and 4b).
`Figure 4a:
`
`Figure 4b:
`
`6. Ensure that the plunger rod is drawn sufficiently back when emptying the vial in order to
`completely empty the filter needle.
`7. Remove the filter needle from the syringe and properly dispose of the filter needle.
`Note: Filter needle is not to be used for intravitreal injection.

`
`Injection Procedure
`2.6
`The intravitreal injection procedure should be carried out under controlled aseptic conditions,
`which include surgical hand disinfection and the use of sterile gloves, a sterile drape, and a
`sterile eyelid speculum (or equivalent). Adequate anesthesia and a topical broad–spectrum
`microbicide should be given prior to the injection.
`
`Immediately following the intravitreal injection, patients should be monitored for elevation in
`intraocular pressure. Appropriate monitoring may consist of a check for perfusion of the optic
`nerve head or tonometry. If required, a sterile paracentesis needle should be available.
`
`Following intravitreal injection, patients should be instructed to report any symptoms suggestive
`of endophthalmitis or retinal detachment (e.g., eye pain, redness of the eye, photophobia,
`blurring of vision) without delay [see Patient Counseling Information (17)].
`
`Each vial should only be used for the treatment of a single eye. If the contralateral eye requires
`treatment, a new vial should be used and the sterile field, syringe, gloves, drapes, eyelid
`speculum, filter, and injection needles should be changed before EYLEA is administered to the
`other eye.
`
`After injection, any unused product must be discarded.

`
`CONTRAINDICATIONS
`
`Ocular or Periocular Infections
`4.1
`EYLEA is contraindicated in patients with ocular or periocular infections.
`
`Active Intraocular Inflammation
`4.2
`EYLEA is contraindicated in patients with active intraocular inflammation.
`
`Hypersensitivity
`4.3
`EYLEA is contraindicated in patients with known hypersensitivity to aflibercept or any of the
`excipients in EYLEA. Hypersensitivity reactions may manifest as severe intraocular
`inflammation.
`
`5
`
`WARNINGS AND PRECAUTIONS
`
`Endophthalmitis and Retinal Detachments
`5.1
`Intravitreal injections, including those with EYLEA, have been associated with endophthalmitis
`and retinal detachments [see Adverse Reactions (6.1)]. Proper aseptic injection technique must
`
`always be used when administering EYLEA. Patients should be instructed to report any
`symptoms suggestive of endophthalmitis or retinal detachment without delay and should be
`managed appropriately [see Dosage and Administration (2.6) and Patient Counseling
`Information (17)].
`
`Increase in Intraocular Pressure
`5.2
`Acute increases in intraocular pressure have been seen within 60 minutes of intravitreal injection,
`including with EYLEA [see Adverse Reactions (6.1)]. Sustained increases in intraocular pressure
`have also been reported after repeated intravitreal dosing with vascular endothelial growth factor
`(VEGF) inhibitors. Intraocular pressure and the perfusion of the optic nerve head should be
`monitored and managed appropriately [see Dosage and Administration (2.6)].
`
`Thromboembolic Events
`5.3
`There is a potential risk of arterial thromboembolic events (ATEs) following intravitreal use of
`VEGF inhibitors, including EYLEA. ATEs are defined as nonfatal stroke, nonfatal myocardial
`infarction, or vascular death (including deaths of unknown cause). The incidence of reported
`thromboembolic events in wet AMD studies during the first year was 1.8% (32 out of 1824) in
`the combined group of patients treated with EYLEA. The incidence in the DME studies during
`the first year was 3.3% (19 out of 578) in the combined group of patients treated with EYLEA
`compared with 2.8% (8 out of 287) in the control group. There were no reported thromboembolic
`events in the patients treated with EYLEA in the first six months of the RVO studies.

`
`ADVERSE REACTIONS
`
`The following adverse reactions are discussed in greater detail in the Warnings and Precautions
`(5) section of the labeling:
`
` Endophthalmitis and retinal detachments
`Increased intraocular pressure
`
` Thromboembolic events
`6.1
`Clinical Trials Experience
`Because clinical trials are conducted under widely varying conditions, adverse reaction rates
`observed in the clinical trials of a drug cannot be directly compared to rates in other clinical trials
`of the same or another drug and may not reflect the rates observed in practice.
`
`A total of 2711 patients treated with EYLEA constituted the safety population in seven phase 3
`studies. Among those, 2110 patients were treated with the recommended dose of 2 mg. Serious
`adverse reactions related to the injection procedure have occurred in <0.1% of intravitreal
`injections with EYLEA including endophthalmitis and retinal detachment. The most common
`adverse reactions (≥5%) reported in patients receiving EYLEA were conjunctival hemorrhage,
`eye pain, cataract, vitreous floaters, intraocular pressure increased, and vitreous detachment.
`
`Neovascular (Wet) Age-Related Macular Degeneration (AMD)
`The data described below reflect exposure to EYLEA in 1824 patients with wet AMD, including
`1223 patients treated with the 2-mg dose, in 2 double-masked, active-controlled clinical studies
`(VIEW1 and VIEW2) for 12 months [see Clinical Studies (14.1)].

`
`Less common adverse reactions reported in <1% of the patients treated with EYLEA were
`hypersensitivity, eyelid edema, corneal edema, retinal detachment, injection site hemorrhage,
`and retinal tear.
`
`Immunogenicity
`6.2
`As with all therapeutic proteins, there is a potential for an immune response in patients treated
`with EYLEA. The immunogenicity of EYLEA was evaluated in serum samples. The
`immunogenicity data reflect the percentage of patients whose test results were considered
`positive for antibodies to EYLEA in immunoassays. The detection of an immune response is
`highly dependent on the sensitivity and specificity of the assays used, sample handling, timing of
`sample collection, concomitant medications, and underlying disease. For these reasons,
`comparison of the incidence of antibodies to EYLEA with the incidence of antibodies to other
`products may be misleading.
`
`In the wet AMD, RVO, and DME studies, the pre-treatment incidence of immunoreactivity to
`EYLEA was approximately 1% to 3% across treatment groups. After dosing with EYLEA for
`
`24-52 weeks, antibodies to EYLEA were detected in a similar percentage range of patients.
`There were no differences in efficacy or safety between patients with or without
`immunoreactivity.
`

`
`USE IN SPECIFIC POPULATIONS
`
`Pregnancy
`8.1
` Pregnancy Category C. Aflibercept produced embryo-fetal toxicity when administered every
`
` three days during organogenesis to pregnant rabbits at intravenous doses ≥3 mg per kg, or every
`
`six days at subcutaneous doses ≥0.1 mg per kg. Adverse embryo-fetal effects included increased
`incidences of postimplantation loss and fetal malformations, including anasarca, umbilical
`hernia, diaphragmatic hernia, gastroschisis, cleft palate, ectrodactyly, intestinal atresia, spina
`bifida, encephalomeningocele, heart and major vessel defects, and skeletal malformations (fused
`vertebrae, sternebrae, and ribs; supernumerary vertebral arches and ribs; and incomplete
`ossification). The maternal No Observed Adverse Effect Level (NOAEL) in these studies was
`3 mg per kg. Aflibercept produced fetal malformations at all doses assessed in rabbits and the
`fetal NOAEL was less than 0.1 mg per kg. Administration of the lowest dose assessed in rabbits
`(0.1 mg per kg) resulted in systemic exposure (AUC) that was approximately 10 times the
`systemic exposure observed in humans after an intravitreal dose of 2 mg.
`
`There are no adequate and well-controlled studies in pregnant women. EYLEA should be used
`during pregnancy only if the potential benefit justifies the potential risk to the fetus.
`
`Nursing Mothers
`8.3
`It is unknown whether aflibercept is excreted in human milk. Because many drugs are excreted
`in human milk, a risk to the breastfed child cannot be excluded. EYLEA is not recommended

`
`during breastfeeding. A decision must be made whether to discontinue nursing or to discontinue
`treatment with EYLEA, taking into account the importance of the drug to the mother.
`
`Pediatric Use
`8.4
`The safety and effectiveness of EYLEA in pediatric patients have not been established.
`
`Geriatric Use
`8.5
`In the clinical studies, approximately 76% (2049/2701) of patients randomized to treatment with
`
`EYLEA were ≥65 years of age and approximately 46% (1250/2701) were ≥75 years of age.
`
`No significant differences in efficacy or safety were seen with increasing age in these studies.

`
`DESCRIPTION
`
`EYLEA (aflibercept) is a recombinant fusion protein consisting of portions of human VEGF
`receptors 1 and 2 extracellular domains fused to the Fc portion of human IgG1 formulated as an
`iso-osmotic solution for intravitreal administration. Aflibercept is a dimeric glycoprotein with a
`protein molecular weight of 97 kilodaltons (kDa) and contains glycosylation, constituting an
`additional 15% of the total molecular mass, resulting in a total molecular weight of 115 kDa.
`Aflibercept is produced in recombinant Chinese hamster ovary (CHO) cells.
`
`EYLEA is a sterile, clear, and colorless to pale yellow solution. EYLEA is supplied as a
`preservative-free, sterile, aqueous solution in a single-use, glass vial designed to deliver 0.05 mL
`(50 microliters) of EYLEA (40 mg/mL in 10 mM sodium phosphate, 40 mM sodium chloride,
`0.03% polysorbate 20, and 5% sucrose, pH 6.2).

`
`CLINICAL PHARMACOLOGY
`
`12.1 Mechanism of Action
`Vascular endothelial growth factor-A (VEGF-A) and placental growth factor (PlGF) are
`members of the VEGF family of angiogenic factors that can act as mitogenic, chemotactic, and
`vascular permeability 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 also present on the surface of leucocytes. Activation of these receptors by
`VEGF-A can result in neovascularization and vascular permeability.
`
`Aflibercept acts as a soluble decoy receptor that binds VEGF-A and PlGF, and thereby can
`inhibit the binding and activation of these cognate VEGF receptors.

`Neovascular (Wet) Age-Related Macular Degeneration (AMD)
`
`In the clinical studies anatomic measures of disease activity improved similarly in all treatment
`groups from baseline to week 52. Anatomic data were not used to influence treatment decisions
`[see Clinical Studies (14.1)].
`
`Macular Edema Following Retinal Vein Occlusion (RVO)
`
`Reductions in mean retinal thickness were observed in COPERNICUS, GALILEO, and
`VIBRANT at week 24 compared to baseline. Anatomic data were not used to influence treatment
`decisions [see Clinical Studies (14.2), (14.3)].
`
`Diabetic Macular Edema (DME)
`
`Reductions in mean retinal thickness were observed in VIVID and VISTA at week 52 compared
`to baseline. Anatomic data were not used to influence EYLEA treatment decisions [see Clinical
`Studies (14.4)].
`
`Pharmacokinetics
`12.3
`EYLEA is administered intravitreally to exert local effects in the eye. In patients with wet AMD,
`RVO, or DME, following intravitreal administration of EYLEA, a fraction of the administered
`dose is expected to bind with endogenous VEGF in the eye to form an inactive aflibercept:
`VEGF complex. Once absorbed into the systemic circulation, aflibercept presents in the plasma
`as free aflibercept (unbound to VEGF) and a more predominant stable inactive form with
`circulating endogenous VEGF (i.e., aflibercept: VEGF complex).
`
`Absorption/Distribution
`
`Following intravitreal administration of 2 mg per eye of EYLEA to patients with wet AMD,
`RVO, and DME, the mean Cmax of free aflibercept in the plasma was 0.02 mcg/mL (range: 0 to
`0.054 mcg/mL), 0.05 mcg/mL (range: 0 to 0.081 mcg/mL), and 0.03 mcg/mL (range: 0 to 0.076
`
` mcg/mL), respectively and was attained in 1 to 3 days. The free aflibercept plasma
`concentrations were undetectable two weeks post-dosing in all patients. Aflibercept did not
`accumulate in plasma when administered as repeated doses intravitreally every 4 weeks. It is
`estimated that after intravitreal administration of 2 mg to patients, the mean maximum plasma
`concentration of free aflibercept is more than 100 fold lower than the concentration of aflibercept
`required to half-maximally bind systemic VEGF.
`
`The volume of distribution of free aflibercept following intravenous (I.V.) administration of
`aflibercept has been determined to be approximately 6L.
`
`Metabolism/Elimination
`
`Aflibercept is a therapeutic protein and no drug metabolism studies have been conducted.
`Aflibercept is expected to undergo elimination through both target-mediated disposition via

`binding to free endogenous VEGF and metabolism via proteolysis. The terminal elimination
`half-life (t1/2) of free aflibercept in plasma was approximately 5 to 6 days after I.V.
`administration of doses of 2 to 4 mg/kg aflibercept.
`
`Specific Populations
`
`Renal Impairment
`
`Pharmacokinetic analysis of a subgroup of patients (n=492) in one wet AMD study, of which
`43% had renal impairment (mild n=120, moderate n=74, and severe n=16), revealed no
`differences with respect to plasma concentrations of free aflibercept after intravitreal
`administration every 4 or 8 weeks. Similar results were seen in patients in a RVO study and in
`
`patients in a DME study. No dose adjustment based on renal impairment status is needed for
`either wet AMD, RVO, or DME patients.
`
`Other
`
`No special dosage modification is required for any of the populations that have been studied
`(e.g., gender, elderly).

`
`NONCLINICAL TOXICOLOGY
`
`Carcinogenesis, Mutagenesis, Impairment of Fertility
`13.1
`No studies have been conducted on the mutagenic or carcinogenic potential of aflibercept.
`Effects on male and female fertility were assessed as part of a 6-month study in monkeys with
`intravenous administration of aflibercept at weekly doses ranging from 3 to 30 mg per kg.
`Absent or irregular menses associated with alterations in female reproductive hormone levels and
`changes in sperm morphology and motility were observed at all dose levels. In addition, females
`showed decreased ovarian and uterine weight accompanied by compromised luteal development
`and reduction of maturing follicles. These changes correlated with uterine and vaginal atrophy. A
`No Observed Adverse Effect Level (NOAEL) was not identified. Intravenous administration of
`the lowest dose of aflibercept assessed in monkeys (3 mg per kg) resulted in systemic exposure
`
`(AUC) that was approximately 1500 times higher than the systemic exposure observed in
`humans after an intravitreal dose of 2 mg. All changes were reversible within 20 weeks after
`cessation of treatment.
`
`Animal Toxicology and/or Pharmacology
`13.2
`Erosions and ulcerations of the respiratory epithelium in nasal turbinates in monkeys treated with
`aflibercept intravitreally were observed at intravitreal doses of 2 or 4 mg per eye. At the NOAEL
`of 0.5 mg per eye in monkeys, the systemic exposure (AUC) was 56 times higher than the
`exposure observed in humans after an intravitreal dose of 2 mg. Similar effects were not seen in
`clinical studies [see Clinical Studies (14)].

`CLINICAL STUDIES
`
`Neovascular (Wet) Age-Related Macular Degeneration (AMD)
`14.1
`The safety and efficacy of EYLEA were assessed in two randomized, multi-center, double-
`masked, active-controlled studies in patients with wet AMD. A total of 2412 patients were
`treated and evaluable for efficacy (1817 with EYLEA) in the two studies (VIEW1 and VIEW2).
`In each study, patients were randomly assigned in a 1:1:1:1 ratio to 1 of 4 dosing regimens:
`1) EYLEA administered 2 mg every 8 weeks following 3 initial monthly doses (EYLEA 2Q8);
`2) EYLEA administered 2 mg every 4 weeks (EYLEA 2Q4); 3) EYLEA 0.5 mg administered
`every 4 weeks (EYLEA 0.5Q4); and 4) ranibizumab administered 0.5 mg every 4 weeks
`(ranibizumab 0.5 mg Q4). Patient ages ranged from 49 to 99 years with a mean of 76 years.
`
`In both studies, the primary efficacy endpoint was the proportion of patients who maintained
`vision, defined as losing fewer than 15 letters of visual acuity at week 52 compared to baseline.
`Data are available through week 52. Both EYLEA 2Q8 and EYLEA 2Q4 groups were shown to
`have efficacy that was clinically equivalent to the ranibizumab 0.5 mg Q4 group.
`
`Detailed results from the analysis of the VIEW1 and VIEW2 studies are shown in Table 4 and
`Figure 8 below.
