1 INDICATIONS AND USAGE EYLEA HD is indicated for the treatment of: EYLEA HD is a vascular endothelial growth factor (VEGF) inhibitor indicated for the treatment of patients with: Neovascular (Wet) Age-Related Macular Degeneration (nAMD) ( 1.1 ) Diabetic Macular Edema (DME) ( 1.2 ) Diabetic Retinopathy (DR) ( 1.3 ) Macular Edema Following Retinal Vein Occlusion (RVO) ( 1.4 ) 1.1 Neovascular (Wet) Age-Related Macular Degeneration (nAMD) 1.2 Diabetic Macular Edema (DME) 1.3 Diabetic Retinopathy (DR) 1.4 Macular Edema Following Retinal Vein Occlusion (RVO)

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 (≥3%) reported in patients treated with EYLEA HD were cataract, conjunctival hemorrhage, corneal epithelium defect, intraocular pressure increased, ocular discomfort/eye pain/eye irritation, retinal hemorrhage, vision blurred, vitreous detachment, and vitreous floaters.

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 1755 patients were treated with EYLEA HD and 804 patients were treated with EYLEA 2 mg in three clinical studies.

The most common adverse reactions reported in ≥3% of patients treated with EYLEA HD were cataract, conjunctival hemorrhage, corneal epithelium defect, intraocular pressure increased, ocular discomfort/eye pain/eye irritation, retinal hemorrhage, vision blurred, vitreous detachment and vitreous floaters.

Neovascular (Wet) Age-Related Macular Degeneration (AMD) and Diabetic Macular Edema (DME) The data described below reflect exposure to EYLEA HD administered every 12 weeks (HDq12), EYLEA HD administered every 16 weeks (HDq16), or EYLEA 2 mg administered every 8 weeks (2q8) in controlled clinical studies (PULSAR and PHOTON), each for 96 weeks [see Clinical Studies (14.1 , 14.2) ].

Macular Edema Following Retinal Vein Occlusion (RVO) The data described below reflects 36 weeks exposure to EYLEA HD administered every 8 weeks (HDq8) after 3 or 5 initial monthly doses (HDq4), or EYLEA 2 mg administered every 4 weeks (2q4) in a controlled clinical study (QUASAR).

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).
