EYLEA® HD (aflibercept) Injection 8 mg Presentations at ARVO Reinforce Sustained and Clinically Meaningful Outcomes in Serious Retinal Diseases

TARRYTOWN, N.Y., April 29, 2024 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced the presentation of positive long-term results and subgroup analyses from the pivotal clinical program of EYLEA® HD (aflibercept) Injection 8 mg. The presentations are part of 14 accepted abstracts on EYLEA HD and EYLEA® (aflibercept) Injection 2 mg that will be shared at the Association for Research in Vision and Ophthalmology (ARVO) annual meeting from May 5 to 9 in Seattle.

“Our extensive data presentations at ARVO showcase the differentiated efficacy, safety and durability of EYLEA HD, and demonstrate our commitment to advancing retinal care for patients who are at risk of losing vision,” said Boaz Hirshberg, M.D., Senior Vice President, Clinical Development, Internal Medicine at Regeneron. “Since its FDA approval, we have seen growing use and positive patient and physician experiences with EYLEA HD in both treatment-experienced and treatment-naïve patients. The ARVO presentations highlight the encouraging real-world impact of EYLEA HD seen so far and reinforce its potential as a new standard-of-care for people living with wet age-related macular degeneration, diabetic macular edema and diabetic retinopathy.”

Notable podium presentations at ARVO include:

  • One-year (48 week) data from the PHOTON trial investigating EYLEA HD in diabetic macular edema (DME) patients with or without prior treatment, compared to EYLEA.
  • Two-year (96 week) results from the PULSAR trial investigating EYLEA HD in patients with wet age-related macular degeneration (wAMD), compared to EYLEA, which will feature a post-hoc analysis on the correlation of key baseline disease characteristics in wAMD to dosing intervals of EYLEA HD.
  • A PULSAR subgroup analysis evaluating visual and anatomic improvements with EYLEA HD, compared to EYLEA, based on baseline best corrected visual acuity (BCVA), corneal refractive therapy (CRT), choroidal neovascularization (CNV) type and race.

In addition, a population pharmacokinetics analysis will be presented to elucidate the observed extended durability of EYLEA HD compared to EYLEA. These data provide a biological rationale for the approved extended dosing regimens of EYLEA HD.

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

EYLEA HD (known as Eylea™ 8 mg in the European Union and other ex-US countries) is being jointly developed by Regeneron and Bayer AG. In the U.S., Regeneron maintains exclusive rights to EYLEA HD and EYLEA. Bayer has licensed the exclusive marketing rights outside of the U.S., where the companies share equally the profits from sales of EYLEA HD and EYLEA following any regulatory approvals.

About the EYLEA HD Clinical Trial Program
PULSAR in wAMD and PHOTON in DME are double-masked, active-controlled pivotal trials that are being conducted in multiple centers globally. In both trials, patients were randomized into 3 treatment groups to receive either: EYLEA HD every 12 weeks, EYLEA HD every 16 weeks, or EYLEA every 8 weeks. The lead sponsors of the trials were Bayer for PULSAR and Regeneron for PHOTON.

Patients treated with EYLEA HD in both trials had 3 initial monthly doses, and patients treated with EYLEA received 3 initial doses in PULSAR and 5 in PHOTON. In the first year, patients in the EYLEA HD groups could have their dosing intervals shortened down to an every 8-week interval if protocol-defined criteria for disease progression were observed. Intervals could not be extended until the second year of the study. Patients in all EYLEA groups maintained a fixed 8-week dosing regimen throughout their participation in the trials. One-year results from the PULSAR and PHOTON trials were recently published in The Lancet.

Two-year data from the pivotal PULSAR trial were originally presented at the EURETINA Congress in October 2023, and two-year data from the pivotal PHOTON trial were first presented at the American Society of Retina Specialists annual meeting in July 2023.

CANDELA was a Regeneron-sponsored Phase 2 trial investigating the safety and efficacy of EYLEA HD extended dosing regimens compared to EYLEA in wAMD patients.

About wAMD and Diabetic Eye Disease
wAMD is a retinal disease that may affect people as they age. It occurs when abnormal blood vessels grow and leak fluid under the macula, the part of the eye responsible for sharp central vision and seeing fine detail. This fluid can damage and scar the macula, which can cause vision loss. An estimated 1.4 million Americans have wAMD.

DR is an eye disease characterized by microvascular damage to the blood vessels in the retina often caused by poor blood sugar control in people with diabetes. The disease generally starts as nonproliferative diabetic retinopathy (NPDR) and often has no warning signs or symptoms. NPDR may progress to proliferative diabetic retinopathy (PDR), a stage of the disease in which abnormal blood vessels grow onto the surface of the retina and into the vitreous cavity, potentially causing severe vision loss.

DME can occur at any stage of DR as the blood vessels in the retina become increasingly fragile and leak fluid, potentially causing visual impairment. In the U.S., approximately 1.5 million adults are diagnosed with DME, while approximately 6 million people have DR without DME.

About Ophthalmology at Regeneron
At Regeneron, we relentlessly pursue groundbreaking innovations in eye care science to help maintain the eye health of the millions of Americans impacted by vision-threatening conditions. Over a decade ago, our breakthrough scientific research resulted in the development of EYLEA, a vascular endothelial growth factor (VEGF) inhibitor designed to block the growth of new blood vessels and decrease the ability of fluid to pass through blood vessels in the eye. EYLEA has since brought fundamental change to the retinal disease treatment landscape and is supported by a robust body of research that includes eight pivotal Phase 3 trials, 11 years of real-world experience, and more than 70 million EYLEA injections globally.

Regeneron continues to advance our anti-angiogenesis expertise with new solutions with the aim of offering optimal flexibility for a broad group of patients and eye care professionals. This includes EYLEA HD, which has been developed with the aim of extending the time between injections, while maintaining the vision gains, anatomic benefits and safety previously observed with EYLEA.



EYLEA® HD (aflibercept) 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) 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).


  • 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 and retinal detachment (separation of retina from back of the eye) can occur. Inflammation in the eye has been reported with the use of EYLEA HD and EYLEA.
  • 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.
  • Contact your doctor right away if you think you or your baby might be experiencing any side effects, including eye pain or redness, light sensitivity, or blurring of vision, after an injection.
  • For additional safety information, please talk to your doctor and see the full Prescribing Information for EYLEA HD and EYLEA.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit or call 1-800-FDA-1088.
