If approved, extended regimen would provide a longer treatment interval and additional dosing flexibility, alongside approved every 4- and 8-week dosing regimens

Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced the U.S. Food and Drug Administration (FDA) has accepted for review the EYLEA^® (aflibercept) Injection supplemental Biologics License Application (sBLA) for an every 16-week 2 mg dosing regimen (after initial monthly doses) in patients with diabetic retinopathy (DR). The target action date for the FDA decision is February 28, 2023. 

DR is the leading cause of blindness among working-age American adults, affecting more than 8 million people in the U.S. alone. In 2019, EYLEA was approved for the treatment of all stages of DR with a dosing regimen of every 4 or 8 weeks after five initial monthly doses. If approved, the 16-week dosing regimen could offer certain patients a potentially longer treatment interval and doctors with greater flexibility to individualize treatment.

The sBLA is supported by data from the Phase 3 PANORAMA trial investigating every 8- and 16-week EYLEA dosing regimens, versus sham, in patients with severe non-proliferative diabetic retinopathy (NPDR) without diabetic macular edema (DME). The submission was further supported by data from the NIH-sponsored Protocol W trial investigating an EYLEA every 16-week dosing regimen in patients with moderate to severe NPDR without center-involved DME versus sham.

At 1 year, PANORAMA met its primary endpoint of proportion of patients with ≥2-step improvement in Diabetic Retinopathy Severity Scale (DRSS) score. At 2 years, in both the PANORAMA and Protocol W trials, a greater proportion of patients receiving EYLEA every 16-weeks experienced a ≥2-step improvement in DRSS score, along with greater reductions in the risk of developing vision-threatening complications, versus sham. The rates of serious ocular adverse events and intraocular inflammation in patients treated with EYLEA every 16 weeks were similar across both studies.

In addition to DR with a 4- or 8-week dosing regimen, EYLEA is approved for the treatment of neovascular (Wet) age-related macular degeneration, macular edema following retinal vein occlusion and DME. The potential use of the 16-week dosing regimen for EYLEA in DR has not been fully evaluated by any regulatory authority.

About Diabetic Retinopathy (DR)
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 NPDR and often has no warning signs or symptoms. NPDR may progress to 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 3.5 million people have DR without DME.

About EYLEA
EYLEA is a VEGF inhibitor formulated as an injection for the eye. It is designed to block the growth of new blood vessels and decrease the ability of fluid to pass through blood vessels (vascular permeability) in the eye by blocking VEGF-A and placental growth factor (PLGF), two growth factors involved in angiogenesis. The EYLEA safety and efficacy profile is supported by a robust body of research that includes eight pivotal Phase 3 trials, 10 years of real-world experience and more than 50 million EYLEA injections globally.

IMPORTANT EYLEA INDICATIONS AND SAFETY INFORMATION

EYLEA^® (aflibercept) Injection 2 mg (0.05 mL) 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), and Diabetic Retinopathy (DR).

• EYLEA^® (aflibercept) Injection is a prescription medicine administered by injection into the eye. You should not use 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, including aflibercept.
• Injections into the eye with 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.
• In some patients, injections with 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.
• 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.
• The most common side effects reported in patients receiving EYLEA were increased redness in the eye, eye pain, cataract, vitreous (gel-like substance) detachment, vitreous floaters, moving spots in the field of vision, and increased pressure in the eye.
• You may experience temporary visual changes after an 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 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.

You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.
