- At 3 years of EYLEA HD treatment, the vast majority of patients maintained visual and anatomic improvements while achieving extended dosing regimens, including those of just twice a year: 77%, 58%, 40% and 24% achieved last assigned dosing intervals of ≥3, ≥4, ≥5 and 6 months, respectively
- At 3 years, the vast majority of patients who switched to EYLEA HD from a fixed 2-month dosing regimen with EYLEA (aflibercept) injection 2 mg maintained visual and anatomic improvements while rapidly extending their dosing intervals: 79%, 43% and 16% achieved last assigned dosing intervals of ≥3, ≥4 and ≥5 months, respectively
- Results add to growing body of evidence showing ability of EYLEA HD to extend dosing intervals, including previously presented data in diabetic macular edema following 3 years of EYLEA HD treatment in which 88%, 68%, 48% and 28% of patients achieved a last assigned dosing interval of ≥3, ≥4, ≥5 and 6 months, respectively
Regeneron Pharmaceuticals, Inc. announced positive 3-year (156-week) results for EYLEA HD (aflibercept) Injection 8 mg in patients with wet age-related macular degeneration (wAMD) from an extension study of the phase 3 PULSAR trial.
The results were presented Feb. 8 at the virtual Angiogenesis (Angiogenesis, Exudation, and Degeneration) 2025 annual meeting. Similar to the three-year results for the pivotal PHOTON trial in diabetic macular edema (DME), the longer-term wAMD data demonstrated the vast majority of EYLEA HD patients who entered the extension study sustained the visual gains and anatomic improvements achieved by the end of the second year, while also achieving substantially longer treatment intervals.
Additionally, patients who switched from EYLEA (aflibercept) Injection 2 mg to EYLEA HD at the beginning of the third year were also able to maintain vision and anatomic improvements through the end of the third year, but with longer dosing intervals and fewer injections.
“Patients with wet age-related macular degeneration are older and often need assistance in getting to their doctors’ offices. Reducing their treatment burden can be transformative for their care,” said W. Lloyd Clark, MD, Palmetto Retinal Center, and assistant clinical professor of Ophthalmology at the University of South Carolina School of Medicine. “Impressively, the latest three-year EYLEA HD results show a substantial portion of patients were able to sustain visual and anatomic benefits with only two doses a year. This adds yet another notable piece of evidence to an already remarkable body of data supporting EYLEA HD.”
In PULSAR, EYLEA HD patients were initially randomized at baseline to either 3- or 4-month dosing intervals (after three initial monthly doses). If pre-specified criteria were met, dosing intervals could be shortened throughout the trial or extended in the second and third years.
As previously presented, 88% of all EYLEA HD patients maintained ≥3-month dosing intervals at the end of 2 years. Patients could then participate in an optional extension study for an additional 60 weeks.
Of the EYLEA HD patients (n=375) who completed the full 3 years of treatment:
- Nearly 60% had a last assigned dosing interval of ≥4 months, with 40% and 24% having a last assigned dosing interval of ≥5 and 6 months, respectively, at the end of 3 years of treatment.
- Vision gains and anatomical improvements – including robust reductions in retinal thickness – that were achieved through year 2 were sustained through year 3 in the extension study.
Patients in the PULSAR comparator arm received EYLEA as a fixed 2-month dosing regimen (after three initial monthly doses) for 96 weeks. These patients had the option to enter the extension study at week 96 and were switched to a 3-month dosing interval with EYLEA HD.
Of these patients who completed the extension study (n=186), vision and anatomic improvements were maintained after switching to EYLEA HD, with 79% and 43% having a last assigned dosing interval of ≥3 and ≥4 months, respectively, at week 156.
The safety profile of EYLEA HD continued to be similar to EYLEA through 3 years and remained generally consistent with the known safety profile of EYLEA HD in its pivotal trials.
Ocular treatment emergent adverse events (TEAEs) occurring in ≥4% of all patients included cataract, retinal hemorrhage, reduction of visual acuity, vitreous floaters, and increase of intraocular pressure.
The rate of intraocular inflammation was 2.4% for the patients that switched from EYLEA to EYLEA HD, and 1.9% for the EYLEA HD patients randomized at baseline.
The three-year data from the PHOTON trial for EYLEA HD in DME were previously presented at the American Academy of Ophthalmology annual meeting in October 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.
About the EYLEA HD Clinical Trial Program
PULSAR in wAMD and PHOTON in DME/diabetic retinopathy (DR) are double-masked, active-controlled pivotal trials that were conducted in multiple centers globally.
In both trials, patients were randomized into 3 treatment groups to receive either: EYLEA HD every 3 months, EYLEA HD every 4 months, or EYLEA every 2 months.
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 2-month interval if protocol-defined criteria for disease progression were observed. Intervals could not be extended until the second year of the trial.
Patients in all EYLEA groups maintained a fixed 2-month dosing regimen throughout their participation in the two-year trials.
In both trials, there was an optional extension study starting at week 96, with all participating patients receiving EYLEA HD through week 156.
Patients initially randomized to EYLEA in PULSAR, were switched to EYLEA HD at the start of the extension study and immediately assigned to a 3-month dosing interval.
Dosing intervals for all patients in the extension study could be shortened or extended by 2-week increments if protocol-defined criteria were met, with a minimum dosing interval of every 2 months and a maximum dosing interval of every 6 months.

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.
