2 DOSAGE AND ADMINISTRATION Neovascular (Wet) Age-Related Macular Degeneration (AMD) The recommended dose for EYDENZELT is 2 mg (0.05 mL of 40 mg/mL solution) administered by intravitreal injection every 4 weeks (approximately every 28 days, monthly) for the first 3 months, followed by 2 mg (0.05 mL of 40 mg/mL solution) via intravitreal injection once every 8 weeks (2 months). ( 2.5 ) Although EYDENZELT may be dosed as frequently as 2 mg every 4 weeks (approximately every 25 days, monthly), additional efficacy was not demonstrated in most patients when aflibercept was dosed every 4 weeks compared to every 8 weeks. Some patients may need every 4 week (monthly) dosing after the first 12 weeks (3 months). ( 2.5 ) Although not as effective as the recommended every 8 week dosing regimen, patients may also be treated with one dose every 12 weeks after one year of effective therapy. Patients should be assessed regularly.

Although EYDENZELT may be dosed as frequently as 2 mg every 4 weeks (approximately every 25 days, monthly), additional efficacy was not demonstrated in most patients when aflibercept was dosed every 4 weeks compared to every 8 weeks [see Clinical Studies (14.5) ] . Some patients may need every 4 week (monthly) dosing after the first 20 weeks (5 months). 2.6 Preparation for Administration - Pre-filled Syringe The EYDENZELT pre-filled syringe is sterile and for one-time use in one eye only. It should be inspected visually prior to administration. Do not use if particulates, cloudiness, or discoloration are visible, or if the package is open or damaged. Do not use if any part of the pre-filled syringe is damaged or if the syringe cap is detached from the Luer lock. The intravitreal injection should be performed with a 30-gauge × ½-inch injection needle (not included). The pre-filled syringe contains more than the recommended dose of 2 mg aflibercept-boav (equivalent to 0.05 mL). Discard the excess volume prior to administration. PRE-FILLED SYRINGE DESCRIPTION – Figure 1: Use aseptic technique to carry out the following steps. 1. Open the Carton. When ready to administer EYDENZELT, open the carton and remove sterilized blister pack. Carefully peel open the sterilized blister pack ensuring the sterility of its contents. Keep the pre-filled syringe in the sterilized blister pack until you are ready for assembly. 2. Remove the Pre-filled Syringe. Using aseptic technique, remove the pre-filled syringe from the sterilized blister pack. 3. Twist Off the Syringe Cap. Twist off (do not snap off) the syringe cap by holding the pre-filled syringe in one hand and the syringe cap with the thumb and forefinger of the other hand (see Figure 2 ). Note: To avoid compromising the sterility of the product, do not pull back on the plunger. Figure 2: 4. Attach the Needle to the Pre-filled Syringe. Using aseptic technique, firmly twist a 30-gauge × ½-inch injection needle onto the Luer lock syringe tip (see Figure 3 ). Figure 3: Note: When ready to administer EYDENZELT, remove the plastic needle shield from the needle. 5. Check for Air Bubbles. Hold the pre-filled syringe with the needle pointing up and check the pre-filled syringe for bubbles (see Figure 4a ). If there are bubbles, gently tap the pre-filled syringe with your finger until the bubbles rise to the top (see Figure 4b ). Figure 4a: Figure 4b: 6. Remove Air bubbles and Set the Dose. To remove all bubbles and to expel excess drug, SLOWLY depress the plunger rod to align the plunger dome edge (see Figure 5a ) with the dosing marker shown on the barrel of the pre-filled syringe (equivalent to 0.05 mL) (see Figure 5b ). Figure 5a: Figure 5b: 7. The pre-filled syringe is for one-time use is one eye only. After injection any unused product must be discarded. Figure 1 Figure 2 Figure 3 Figure 4a Figure 4b Figure 5a Figure 5b 2.7 Preparation for Administration - Vial EYDENZELDT should be inspected visually prior to administration. If particulates, cloudiness, or discoloration are visible, the vial must not be used. The glass vial is for one-time use in one eye only. Use aseptic technique to carry out the following preparation steps: Prepare for intravitreal injection with the following medical devices for single use (included): a 5 micron sterile filter needle (18-gauge × 1 ½ inch) a 1 mL sterile Luer lock Syringe (with marking to measure 0.05 mL) a sterile injection needle (30-gauge × ½ inch) 1. Remove the protective plastic cap from the vial (see Figure 6 ). Figure 6: 2. Disinfect the top of the vial with an alcohol wipe (see Figure 7 ). Figure 7: 3. Remove the 18-gauge × 1½-inch, 5-micron, filter needle and the 1-mL syringe from their packaging. Attach the filter needle to the syringe by twisting it onto the Luer lock syringe tip (see Figure 8 ). Figure 8: 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 EYDENZELDT 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 Figure 9 ). Figure 9: 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. 8. Remove the 30-gauge × ½-inch injection needle from its packaging and attach the injection needle to the syringe by firmly twisting the injection needle onto the Luer lock syringe tip (see Figure 10 ). Figure 10: 9. When ready to administer EYDENZELT, remove the plastic needle cap from the needle (see Figure 11 ). Figure 11: 10. Holding the syringe with the needle pointing up, check the syringe for bubbles. If there are bubbles, gently tap the syringe with your finger until the bubbles rise to the top (see Figure 12 ). Figure 12: 11. To remove all of the air bubbles and to expel excess drug, SLOWLY depress the plunger so that the plunger tip aligns with the line that marks 0.05 mL on the syringe (see Figure 13 ). Figure 13: Figure 6 Figure 7 Figure 8 Figure 9 Figure 10 Figure 11 Figure 12 Figure 13 2.8 Injection Procedure 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. Pre-filled syringe : Inject by pressing the plunger carefully and with constant pressure. Do not apply additional pressure once the plunger has reached the bottom of the syringe. A small residual volume may remain in the syringe after a full dose has been injected. This is normal. Do not administer any residual solution observed in the syringe. 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 and/or caregivers should be instructed to report any signs and/or 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 sterile, pre-filled syringe or vial should only be used for the treatment of a single eye. If the contralateral eye requires treatment, a new sterile, pre-filled syringe or vial should be used and the sterile field, syringe, gloves, drapes, eyelid speculum, filter, and injection needles should be changed before EYDENZELT is administered to the other eye. After injection, any unused product must be discarded.

6 ADVERSE REACTIONS The following potentially serious adverse reactions are described elsewhere in the labeling: Hypersensitivity [see Contraindications (4.3) ] Endophthalmitis, Retinal Detachments, and Retinal Vasculitis with or without Occlusion [see Warnings and Precautions (5.1) ] Increase in intraocular pressure [see Warnings and Precautions (5.2) ] Thromboembolic events [see Warnings and Precautions (5.3) ] The most common adverse reactions (≥5%) reported in patients receiving aflibercept were conjunctival hemorrhage, eye pain, cataract, vitreous detachment, vitreous floaters, and intraocular pressure increased.

A total of 2980 adult patients treated with aflibercept constituted the safety population in eight phase 3 studies. Among those, 2379 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 aflibercept including endophthalmitis and retinal detachment. The most common adverse reactions (≥5%) reported in patients receiving aflibercept were conjunctival hemorrhage, eye pain, cataract, vitreous detachment, vitreous floaters, and intraocular pressure increased. Neovascular (Wet) Age-Related Macular Degeneration (AMD) The data described below reflect exposure to aflibercept in 1824 patients with wet AMD, including 1223 patients treated with the 2-mg dose, in 2 double-masked, controlled clinical studies (VIEW1 and VIEW2) for 24 months (with active control in year 1) [see Clinical Studies (14.1) ]. Safety data observed in the aflibercept group in a 52-week, double-masked, Phase 2 study were consistent with these results.

Safety data observed in 269 patients with nonproliferative diabetic retinopathy (NPDR) through week 52 in the PANORAMA trial were consistent with those seen in the phase 3 VIVID and VISTA trials (see Table 3 above). 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of aflibercept. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Eye disorders : retinal vasculitis and occlusive retinal vasculitis related to intravitreal injection with aflibercept (reported at a rate of 0.6 and 0.2 per 1 million injections, respectively, based on postmarketing experience from November 2011 until November 2023).

12.3 Pharmacokinetics Aflibercept is administered intravitreally to exert local effects in the eye. In patients with wet AMD, RVO, or DME, following intravitreal administration of aflibercept, 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 aflibercept to patients with wet AMD, RVO, and DME, the mean C max 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 dosage modification is required based on gender or in the elderly.
