EYLEA HD led to improved vision with extended dosing intervals, achieving non-inferior vision gains with an every 8-week dosing regimen compared to EYLEA® (aflibercept) Injection 2 mg dosed every 4 weeks February 08, 2025 17:40 ET  | Source: Regeneron Pharmaceuticals, Inc. TARRYTOWN, N.Y., Feb. 08, 2025 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced the first presentation of positive results from the Phase 3 QUASAR trial investigating EYLEA HD® (aflibercept) Injection 8 mg for the treatment of patients with macular edema following retinal vein occlusion (RVO), including those with central, branch and hemiretinal vein occlusions. The data were presented today at the virtual Angiogenesis (Angiogenesis, Exudation, and Degeneration) 2025 annual meeting and will support the submission of a supplemental Biologics License Application to the U.S. Food and Drug Administration (FDA) in the first quarter of 2025. “Retinal vein occlusion is the second most common retinal vascular disease. However, the current treatment paradigm of monthly eye injections can make it challenging for patients to maintain their treatment plan, potentially leading to poor adherence and vision loss,” said Seenu M. Hariprasad, M.D., Chair of the Department of Ophthalmology and Visual Science, The University of Chicago. “Based on these new data, aflibercept 8 mg may offer the potential to halve the number of injections needed, as compared to standard-of-care aflibercept 2 mg and other anti-VEGF therapies.” As presented at Angiogenesis, the QUASAR trial met its primary endpoint at 36 weeks, with both groups of EYLEA HD patients dosed every 8 weeks achieving non-inferior visual acuity gains compared to those receiving EYLEA® (aflibercept) Injection 2 mg dosed every 4 weeks. The EYLEA HD results were consistent across patients with branch retinal vein occlusions, and those with central retinal or hemiretinal vein occlusions. Furthermore, in patients treated with EYLEA HD through 36 weeks, 88% of patients were able to sustain an 8-week dosing regimen following 3 initial monthly doses, and 93% of patients maintained an 8-week dosing regimen after completing 5 initial monthly doses. The safety profile of EYLEA HD (n=591) was similar to EYLEA (n=301) in QUASAR and remained generally consistent with the known safety profile of EYLEA HD in its pivotal trials. Ocular treatment-emergent adverse events (TEAEs) occurring in ≥5% of all EYLEA HD patients included increased ocular pressure (5%); there was one case each of endophthalmitis and retinal vasculitis. The rate of intraocular inflammation was 0.5% for EYLEA HD and 1.3% for EYLEA. Data from QUASAR were first shared in December 2024. EYLEA HD (known as Eylea™ 8 mg in the European Union and Japan) is being jointly developed by Regeneron and Bayer AG. In the U.S., Regeneron maintains exclusive rights to EYLEA and EYLEA HD. Bayer has licensed the exclusive marketing rights outside of the U.S., where the companies share equally the profits from sales of EYLEA and EYLEA HD. The safety and efficacy of EYLEA HD for the treatment of RVO has not been evaluated by any regulatory authority. About the QUASAR TrialQUASAR is a global double-masked, active-controlled Phase 3 trial evaluating the efficacy and safety of EYLEA HD in patients with macular edema secondary to RVO, including those with central retinal vein occlusion, branch retinal vein occlusion, or hemiretinal vein occlusion. In the trial, patients were randomized into three groups to receive either: EYLEA HD every 8 weeks following 3 initial monthly doses; EYLEA HD every 8 weeks following 5 initial monthly doses; or EYLEA every 4 weeks. The primary endpoint was mean change in BCVA from randomization through week 36, as measured by the Early Treatment Diabetic Retinopathy Study letter score. Patients in the EYLEA HD groups can have their dosing intervals shortened to a minimum of every 4 weeks throughout the trial if protocol-defined criteria for disease progression are met. Dosing intervals may be extended based on protocol-defined criteria starting at week 32 for patients who receive EYLEA or EYLEA HD after 3 initial monthly doses or at week 40 for patients who receive EYLEA HD after 5 initial monthly doses, with follow-up planned through week 64. QUASAR is being operationalized by Bayer under a collaboration agreement with Regeneron. About Retinal Vein OcclusionRVO is a common cause of vision loss in adults and the second most common retinal vascular disease. RVO occurs when there is a blockage in a vein in the retina, which leads to a buildup of blood, restricted blood flow, increased pressure and sometimes pain in the eye. RVO may cause sudden blurry vision or vision loss and can ultimately result in serious complications like swelling in the eye called macular edema. A protein called vascular endothelial growth factor (VEGF) is instrumental in causing the vascular leakage that leads to macular edema. When a vein in the retina is blocked, the levels of VEGF increase, which spurs new blood vessel growth. Too much VEGF can lead to the formation of abnormal blood vessels and may cause vision to become blurry. Anti-VEGF injections are commonly used to treat macular edema due to RVO. There are two main types of RVO: central retinal vein occlusion (CRVO) and branch retinal vein occlusion (BRVO). In CRVO, the buildup occurs in the eye’s central retinal vein and in BRVO, the buildup occurs in one of the smaller branch veins. Globally, RVO affects over 28 million people. IMPORTANT SAFETY INFORMATION AND INDICATIONS INDICATIONSEYLEA HD® (aflibercept) Injection 8 mg is a prescription medicine approved for the treatment of patients with Wet Age-Related Macular Degeneration (AMD), Diabetic Macular Edema (DME), and Diabetic Retinopathy (DR). EYLEA® (aflibercept) Injection 2 mg is a prescription medicine approved for the treatment of patients with Wet Age-Related Macular Degeneration (AMD), Macular Edema following Retinal Vein Occlusion (RVO), Diabetic Macular Edema (DME), Diabetic Retinopathy (DR), and Retinopathy of Prematurity (ROP) (0.4 mg). IMPORTANT SAFETY INFORMATION EYLEA HD and EYLEA are administered by injection into the eye. You should not use EYLEA HD or EYLEA if you have an infection in or around the eye, eye pain or redness, or known allergies to any of the ingredients in EYLEA HD or EYLEA, including aflibercept.Injections into the eye with EYLEA HD or EYLEA can result in an infection in the eye, retinal detachment (separation of retina from back of the eye) and, more rarely, serious inflammation of blood vessels in the retina that may include blockage. Call your doctor right away if you or your baby (if being treated with EYLEA for Retinopathy of Prematurity) experience eye pain or redness, light sensitivity, or a change in vision after an injection.In some patients, injections with EYLEA HD or EYLEA may cause a temporary increase in eye pressure within 1 hour of the injection. Sustained increases in eye pressure have been reported with repeated injections, and your doctor may monitor this after each injection.In infants with Retinopathy of Prematurity (ROP), treatment with EYLEA will need extended periods of ROP monitoring.There is a potential but rare risk of serious and sometimes fatal side effects, related to blood clots, leading to heart attack or stroke in patients receiving EYLEA HD or EYLEA.The most common side effects reported in patients receiving EYLEA HD were cataract, increased redness in the eye, increased pressure in the eye, eye discomfort, pain, or irritation, blurred vision, vitreous (gel-like substance) floaters, vitreous detachment, injury to the outer layer of the eye, and bleeding in the back of the eye.The most common side effects reported in patients receiving EYLEA were increased redness in the eye, eye pain, cataract, vitreous detachment, vitreous floaters, moving spots in the field of vision, and increased pressure in the eye.The most common side effects reported in pre-term infants with ROP receiving EYLEA were separation of the retina from the back of the eye, increased redness in the eye, and increased pressure in the eye. Side effects that occurred in adults are considered applicable to pre-term infants with ROP, though not all were seen in clinical studies.You may experience temporary visual changes after an EYLEA HD or EYLEA injection and associated eye exams; do not drive or use machinery until your vision recovers sufficiently.For additional safety information, please talk to your doctor and see the full Prescribing Information for EYLEA HD and EYLEA.
