TARRYTOWN, N.Y., Oct. 21, 2022 /PRNewswire/ -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced the U.S. Food and Drug Administration (FDA) has granted pediatric exclusivity for EYLEA® (aflibercept) Injection. This grant extends the period of U.S. market exclusivity for EYLEA by an additional six months through May 17, 2024.
The pediatric exclusivity determination is based on data from two Phase 3 trials – BUTTERFLEYE and FIREFLEYE – which were submitted in response to the FDA's Written Request to evaluate the use of EYLEA as a treatment for retinopathy of prematurity (ROP) in preterm infants. The two Phase 3 trials also formed the basis of a supplemental Biologics License Application for EYLEA in ROP that was recently accepted for Priority Review by the FDA. The lead sponsors of the trials were Regeneron for BUTTERFLEYE and Bayer for FIREFLEYE.
EYLEA was granted orphan drug designation by the FDA for the treatment of ROP in July 2019. The safety and efficacy of EYLEA for this indication have not been fully evaluated by the FDA and other regulatory authorities.
EYLEA is currently approved in the U.S. for the treatment of patients with wet age-related macular degeneration, macular edema following retinal vein occlusion, diabetic macular edema and diabetic retinopathy.
About EYLEAEYLEA 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.
Bayer and Regeneron are collaborating on the global development of EYLEA. Regeneron maintains exclusive rights of EYLEA in the United States. Bayer has licensed the exclusive marketing rights outside the United States, where the companies share equally the profits from sales of EYLEA.
IMPORTANT EYLEA SAFETY INFORMATION AND INDICATIONS
INDICATIONSEYLEA® (aflibercept) Injection 2 mg (0.05 mL) is indicated for the treatment of patients with Neovascular (Wet) Age-related Macular Degeneration (AMD), Macular Edema following Retinal Vein Occlusion (RVO), Diabetic Macular Edema (DME), and Diabetic Retinopathy (DR).
CONTRAINDICATIONS
- EYLEA is contraindicated in patients with ocular or periocular infections, active intraocular inflammation, or known hypersensitivity to aflibercept or to any of the excipients in EYLEA.
WARNINGS AND PRECAUTIONS
- Intravitreal injections, including those with EYLEA, have been associated with endophthalmitis and retinal detachments. Proper aseptic injection technique must always be used when administering EYLEA. Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay and should be managed appropriately. Intraocular inflammation has been reported with the use of EYLEA.
- Acute increases in intraocular pressure have been seen within 60 minutes of intravitreal injection, including with EYLEA. Sustained increases in intraocular pressure have also been reported after repeated intravitreal dosing with VEGF inhibitors. Intraocular pressure and the perfusion of the optic nerve head should be monitored and managed appropriately.
- There is a potential risk of arterial thromboembolic events (ATEs) following intravitreal use of VEGF inhibitors, including EYLEA. ATEs are defined as nonfatal stroke, nonfatal myocardial infarction, or vascular death (including deaths of unknown cause). The incidence of reported thromboembolic events in wet AMD studies during the first year was 1.8% (32 out of 1824) in the combined group of patients treated with EYLEA compared with 1.5% (9 out of 595) in patients treated with ranibizumab; through 96 weeks, the incidence was 3.3% (60 out of 1824) in the EYLEA group compared with 3.2% (19 out of 595) in the ranibizumab group. The incidence in the DME studies from baseline to week 52 was 3.3% (19 out of 578) in the combined group of patients treated with EYLEA compared with 2.8% (8 out of 287) in the control group; from baseline to week 100, the incidence was 6.4% (37 out of 578) in the combined group of patients treated with EYLEA compared with 4.2% (12 out of 287) in the control group. There were no reported thromboembolic events in the patients treated with EYLEA in the first six months of the RVO studies.
ADVERSE REACTIONS
- Serious adverse reactions related to the injection procedure have occurred in
