`
`Figure 7b
`
`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 treatmentof 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.
`No special dosage modification is required for any of the populations that have been studied
`(e.g., gender, elderly).

` CONTRAINDICATIONS
`
`4.1 Ocular or Periocular Infections
`
`EYLEA is contraindicated in patients with ocular or periocular infections.
`4.2 Active Intraocular Inflammation
`
`EYLEA is contraindicated in patients with active intraocular inflammation.
`4.3 Hypersensitivity
`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
`5.1
`Endophthalmitis and Retinal Detachments
`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 (2.5) and Patient Counseling
`
`Exhibit 2137
`Page 04 of 30
`
`
`
`
`
`ee
`Less common adverse reactions reported in <1% of the patients treated with EYLEA were
`cataract, eyelid edema, corneal edema,retinal tear, hypersensitivity, and endophthalmitis.
`6.3
`Immunogenicity
`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 and CRVOstudies, the pre-treatment incidence of immunoreactivity to EYLEA
`was 1% to 3% across treatment groups. After dosing with EYLEA for 52 weeks (wet AMD), or
`24 weeks (CRVO), antibodies to EYLEA were detectedin a similar percentage range of patients.
`Both in the wet AMD andin the CRVO studies, there were no differences in efficacy or safety
`between patients with or without immunoreactivity.
`8
`USE IN SPECIFIC POPULATIONS
`
`
`
`reported in patients receiving EYLEA were
`The most common adverse reactions (>5%)
`conjunctival hemorrhage,
`eye pain, cataract, vitreous detachment, vitreous
`floaters,
`and increased intraocular pressure.
`6.1
`Injection Procedure
`Serious adverse reactionsrelatedto the injection procedure have occurred in <0.1%of intravitreal
`injections with EYLEA including endophthalmitis,
`traumatic cataract,
`increased intraocular
`pressure, and vitreous detachment.
`6.2 Clinical Studies Experience
`Because Clinical trials are conducted under widely varying conditions, adverse reaction rates
`observedin the clinical trials of a drug cannotbe directly compared to rates in otherclinicaltrials
`of the sameor another drug and maynot reflect the rates observed in practice.
`A total of 2042 patients treated with EYLEA constituted the safety population in four phase 3
`studies. Among those, 1441 patients were treated with the recommended doseof 2 mg.
`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)}.

`
`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, aqueoussolution 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).
`
`Exhibit 2137
`Page 05 of 30
`
`
`
`EYLEA is administered intravitreally to exert local effects in the eye. In patients with wet AMD
`or CRVO, following intravitreal administration of EYLEA, a fraction of the administered dose
`ranibizu-

`is expected to bind with endogenous VEGF in the eye to form an inactive aflibercept: VEGF

`Absorption/Distribution
`Followingintravitreal administration of 2 mg per eye of EYLEA to patients with wetAMD and CRVO,
`Efficacy Outcomes
`the mean Cmax Of free aflibercept in the plasma was 0.02 mcg/mL(range: 0 to 0.054 mcg/mL)
`and 0.05 mcg/mL (range 0 to 0.081 mcg/mL), respectively and wasattained 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
`
`
`°EYLEA group minus the ranibizumab group Email
`(-7.7, 7.0)|(-1.0, 14.1)
`
`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 LV.
`administration of doses of 2 to 4 mg/kgaflibercept.
`Specific Populations
`Renal Impairment
`Pharmacokinetic analysis of a subgroup of patients (n=492) in one wet AMDstudy, 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 CRVO study.
`No dose adjustment based on renal
`impairment status is needed for either wet AMD or
`CRVOpatients.
`13
`NONCLINICAL TOXICOLOGY
`13.1 Carcinogenesis, Mutagenesis, Impairmentof Fertility
`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.
`Absentor irregular menses associated with alterations in female reproductive hormonelevels
`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 notidentified. 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.
`13.2 Animal Toxicology and/or Pharmacology
`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 pereye in monkeys, the systemic exposure (AUC) was 56 times higher than the
`exposure observed in humansafter an intravitreal dose of 2 mg. Similar effects were not seen in
`Clinical studies [see Clinical Studies (14)].

`
`CLINICAL PHARMACOLOGY
`
`12.1 Mechanism of Action
`
`Vascular endothelial growth factor-A (VEGF-A) and placental growth factor (PIGF) 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 receptortyrosine kinases, VEGFR-1
`and VEGFR-2, present on the surface of endothelial cells. PIGF 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 PIGF, and thereby can inhibit
`the binding and activation of these cognate VEGF receptors.
`12.2 Pharmacodynamics
`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).

`CLINICAL STUDIES
`14.1 Neovascular (Wet) Age-Related Macular Degeneration (AMD)
`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 weeksfollowing 3 initial monthly doses
`(EYLEA 208); 2) EYLEA administered 2 mg every 4 weeks (EYLEA 204); 3) EYLEA 0.5 mg
`administered every 4 weeks (EYLEA 0.504); 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 208 and EYLEA 204 groups were
`shownto 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 3
`and Figure 8 below.

`PATIENT COUNSELING INFORMATION
`In the days following EYLEA administration, patients are at risk of developing endophthalmitis
`or retinal detachment. If the eye becomesred, sensitive to light, painful, or develops a change
`in vision, advise patient to seek immediate care from an ophthalmologist [see Warnings and
`Precautions (5.1)).
`injection with
`Patients may experience temporary visual disturbances after an intravitreal
`EYLEA and the associated eye examinations [see Adverse Reactions (6)]. Advise patients not
`to drive or use machinery until visual function has recovered sufficiently.

`14.2 Macular Edema Following Central Retinal Vein Occlusion (CRVO)
`The safety and efficacy of EYLEA were assessed in
`two randomized, multi-center,
`double-masked, sham-controlled studies in patients with macular edema following CRVO.
`A total of 358 patients were treated and evaluable for efficacy (217 with EYLEA)
`in the
`two studies (COPERNICUS and GALILEO). In both studies, patients were randomly assigned in
`a 3:2 ratio to either 2 mg EYLEA administered every 4 weeks (204), or sham injections (control
`group) administered every 4 weeks for a total of 6 injections. Patient ages ranged from 22 to 89
`years with a mean of 64 years.
`In both studies,the primary efficacy endpoint was the proportion of patients who gainedat least
`15 letters in BCVA compared to baseline. At week 24, the EYLEA 2 mg Q4 group wassuperior to
`the control group for the primary endpoint.
`Results from the analysis of the COPERNICUS and GALILEO studies are shown in Table 4
`and Figure 9 below.

`EYLEA Clinical Pharmacology and Formulation
`
`EYLEA® (aflibercept) Injection is
`indicated for the treatment of patients
`with neovascular (Wet) Age-related
`Macular Degeneration (AMD). The
`recommended dose for EYLEA is 2 mg
`administered by intravitreal injection
`every 4 weeks (monthly) for the first
`12 weeks (3 months), followed by 2 mg
`once every 8 weeks (2 months).
`Although EYLEA may be dosed as
`frequently as 2 mg every 4 weeks
`(monthly), additional efficacy was not
`demonstrated when EYLEA was dosed
`every 4 weeks compared to every
`8 weeks.
`
