If approved, EYLEA HD would be the first and only treatment for RVO indicated for up to every 8-week dosing after an initial monthly dosing period 鈥� halving the number of injections that are indicated for all other anti-VEGF therapies

Potential for as frequent as monthly dosing for all approved indications would provide greater dosing flexibility for physicians and patients

TARRYTOWN, N.Y., April 17, 2025 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that the聽U.S. Food and Drug Administration聽(FDA) has accepted for Priority Review the supplemental Biologics License Application (sBLA) for聽EYLEA HD^庐 (aflibercept) Injection 8 mg. The sBLA seeks approval for EYLEA HD for both the treatment of macular edema following retinal vein occlusion (RVO), and for broadening the dosing schedule to include every 4-week (monthly) dosing across approved indications. The FDA target action date is聽August 19, 2025,聽following the use of a Priority Review voucher.

The sBLA is supported by data from across the EYLEA HD clinical program, including the Phase 3 QUASAR trial investigating EYLEA HD in RVO. As previously , QUASAR met its primary endpoint at 36 weeks, with EYLEA HD patients dosed every 8 weeks (after either 3 or 5 monthly doses), achieving non-inferior visual acuity gains compared to those receiving EYLEA^庐 (aflibercept) Injection 2 mg dosed every 4 weeks. Currently, all anti-VEGF therapies approved to treat RVO, including EYLEA, are indicated for monthly dosing.

In QUASAR, the safety profile of EYLEA HD (n=591) was similar to EYLEA (n=301) and remained generally consistent with the known safety profile of EYLEA HD in its pivotal trials for approved indications and with the established safety profile of EYLEA. Increased ocular pressure (5%) was the only ocular treatment-emergent adverse event that occurred in 鈮�5% of all EYLEA HD patients, compared to 1.7% of EYLEA patients. There was one case each of endophthalmitis and retinal vasculitis in all EYLEA HD patients, compared to two cases of endophthalmitis and no cases of retinal vasculitis in EYLEA patients. No cases of occlusive retinal vasculitis were reported. The rate of intraocular inflammation was 0.5% for EYLEA HD and 1.3% for EYLEA.

The safety and efficacy of EYLEA HD for the treatment of RVO and monthly dosing in approved indications has not been evaluated by any regulatory authority.

About the QUASAR Trial
QUASAR 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 best corrected visual acuity (BCVA) from randomization through week 36, as measured by the Early Treatment Diabetic Retinopathy Study letter score.

QUASAR is being operationalized by Bayer under a collaboration agreement with聽Regeneron.

About Retinal Vein Occlusion
RVO 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鈥檚 central retinal vein and in BRVO, the buildup occurs in one of the smaller branch veins. Globally, RVO affects over 28 million people.

About EYLEA HD
Over a decade ago, Regeneron introduced EYLEA, a vascular endothelial growth factor inhibitor, and transformed the treatment paradigm for certain serious chorioretinal vascular diseases. With a well-established efficacy and consistent safety profile from 16 pivotal trials, EYLEA is approved to treat vision-threatening conditions that impact patients from their earliest days, such as retinopathy of prematurity (ROP), to their later years, including diabetic macular edema (DME), diabetic retinopathy (DR), macular edema following retinal vein occlusion (RVO) and wet age-related macular degeneration (wAMD).

Pushing the boundaries of science further to meet patient needs, EYLEA HD was developed to achieve comparable efficacy and safety to EYLEA, but with fewer injections. EYLEA HD is supported by a robust body of research and is currently approved in the U.S. to treat patients with wAMD, DME and DR.

EYLEA HD (known as Eylea鈩� 8 mg in the European Union and Japan) is being jointly developed by Regeneron and Bayer AG. Regeneron maintains exclusive rights to EYLEA and EYLEA HD in the U.S. 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.

IMPORTANT SAFETY INFORMATION AND INDICATIONS

INDICATIONS
EYLEA HD^庐聽(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^庐 (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.
