2 DOSAGE AND ADMINISTRATION Neovascular (Wet) Age-Related Macular Degeneration (AMD): The recommended dose for PAVBLU 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). ( 2.2 ) Although PAVBLU 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). ( 2.2 ) 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. ( 2.2 ) Macular Edema Following Retinal Vein Occlusion (RVO): The recommended dose for PAVBLU is 2 mg (0.05 mL of 40 mg/mL solution) administered by intravitreal injection once every 4 weeks (approximately every 25 days, monthly).

Warnings

5 WARNINGS AND PRECAUTIONS Endophthalmitis, retinal detachments, and retinal vasculitis with or without occlusion may occur following intravitreal injections. Patients and/or caregivers should be instructed to report any signs and/or symptoms suggestive of endophthalmitis, retinal detachment, or retinal vasculitis without delay and should be managed appropriately. ( 5.1 ) Increases in intraocular pressure have been seen within 60 minutes of an intravitreal injection. ( 5.2 ) There is a potential risk of arterial thromboembolic events following intravitreal use of VEGF inhibitors. ( 5.4 ) 5.1 Endophthalmitis, Retinal Detachments, and Retinal Vasculitis with or without Occlusion Intravitreal injections, including those with aflibercept products, have been associated with endophthalmitis and retinal detachments [see Adverse Reactions (6.1) ] and, more rarely, retinal vasculitis with or without occlusion [see Adverse Reactions (6.2) ] . Proper aseptic injection technique must always be used when administering PAVBLU. Patients and/or caregivers should be instructed to report any signs and/or symptoms suggestive of endophthalmitis, retinal detachment, or retinal vasculitis without delay and should be managed appropriately [see Dosage and Administration (2.8) and Patient Counseling Information (17) ] . 5.2 Increase in Intraocular Pressure Acute increases in intraocular pressure have been seen within 60 minutes of intravitreal injection, including with aflibercept products [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 (2.8) ] . 5.4 Thromboembolic Events There is a potential risk of arterial thromboembolic events (ATEs) following intravitreal use of VEGF inhibitors, including aflibercept products. 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 aflibercept compared with 1.5% (9 out of 595) in patients treated with ranibizumab; through 96 weeks, the incidence was 3.3% (60 out of 1824) in the aflibercept group compared with 3.2% (19 out of 595) in the ranibizumab group. The incidence in the DME studies from baseline to week 52 was 3.3% (19 out of 578) in the combined group of patients treated with aflibercept compared with 2.8% (8 out of 287) in the control group; from baseline to week 100, the incidence was 6.4% (37 out of 578) in the combined group of patients treated with aflibercept compared with 4.2% (12 out of 287) in the control group. There were no reported thromboembolic events in the patients treated with aflibercept in the first six months of the RVO studies.

Contraindications

4 CONTRAINDICATIONS Ocular or periocular infections ( 4.1 ) Active intraocular inflammation ( 4.2 ) Hypersensitivity ( 4.3 ) 4.1 Ocular or Periocular Infections PAVBLU is contraindicated in patients with ocular or periocular infections. 4.2 Active Intraocular Inflammation PAVBLU is contraindicated in patients with active intraocular inflammation. 4.3 Hypersensitivity PAVBLU is contraindicated in patients with known hypersensitivity to aflibercept or any of the excipients in PAVBLU. Hypersensitivity reactions may manifest as rash, pruritus, urticaria, severe anaphylactic/anaphylactoid reactions, or severe intraocular inflammation.

Pregnancy

8.1 Pregnancy Risk Summary Adequate and well-controlled studies with aflibercept have not been conducted in pregnant women. Aflibercept produced adverse embryofetal effects in rabbits, including external, visceral, and skeletal malformations. A fetal No Observed Adverse Effect Level (NOAEL) was not identified. At the lowest dose shown to produce adverse embryofetal effects, systemic exposures (based on AUC for free aflibercept) were approximately 6 times higher than AUC values observed in humans after a single intravitreal treatment at the recommended clinical dose (see Data ) . Animal reproduction studies are not always predictive of human response, and it is not known whether aflibercept can cause fetal harm when administered to a pregnant woman. Based on the anti-VEGF mechanism of action for aflibercept [see Clinical Pharmacology (12.1) ] , treatment with aflibercept may pose a risk to human embryofetal development. PAVBLU should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data In two embryofetal development studies, aflibercept produced adverse embryofetal effects when administered every three days during organogenesis to pregnant rabbits at intravenous doses ≥3 mg per kg, or every six days during organogenesis at subcutaneous doses ≥0.1 mg per kg. Adverse embryofetal 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 not identified. At the lowest dose shown to produce adverse embryofetal effects in rabbits (0.1 mg per kg), systemic exposure (AUC) of free aflibercept was approximately 6 times higher than systemic exposure (AUC) observed in adult patients after a single intravitreal dose of 2 mg.

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 (5.4) ] 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. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Amgen Inc. at 1-800-77-AMGEN (1-800-772-6436) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 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 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. Table 1.
