EYLEA® (aflibercept) Injection Approved for the Treatment of Wet Age-Related Macular Degeneration in Europe

TARRYTOWN, N.Y., Nov. 27, 2012 /PRNewswire/ -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that EYLEA® (aflibercept) Injection has been approved by the European Commission for the treatment of patients with neovascular (wet) age-related macular degeneration (wet AMD). According to the European Medicines Agency (EMA) approved Summary of Product Characteristics, EYLEA treatment is initiated with one 2 milligram (mg) injection per month for three consecutive months, followed by one injection every two months. There is no requirement for monitoring by the physician between injections.  After the first twelve months of treatment with EYLEA, the treatment interval may be extended based on visual and anatomic outcomes. In such cases, the frequency of monitoring visits is determined by the treating physician and may be more often than the schedule of injections.

"We are pleased with the approval of EYLEA in the E.U.," said George D. Yancopoulos, M.D., Ph.D., Chief Scientific Officer of Regeneron and President of Regeneron Laboratories. "We, along with our partner, Bayer HealthCare, look forward to providing this new treatment option which will allow for every other month dosing, following three initial monthly injections, to wet AMD patients in the European Union."

EYLEA was approved for the treatment of neovascular (wet) AMD in the United States in November 2011 and in Japan, Australia, Switzerland, and other countries this year. Bayer HealthCare plans to launch EYLEA in these countries later in 2012 and into 2013. In the United States, EYLEA was also approved for the treatment of Macular Edema following Central Retinal Vein Occlusion (CRVO) in September 2012. 

Bayer HealthCare and Regeneron are collaborating on the global development of EYLEA. Regeneron maintains exclusive rights to EYLEA in the United States. Bayer HealthCare has licensed the exclusive marketing rights outside the United States, where the companies will share equally the profits from sales of EYLEA, except for Japan where Regeneron will receive a royalty on net sales.

About EYLEA® (aflibercept) Injection For Intravitreal Injection

Vascular Endothelial Growth Factor (VEGF) is a naturally occurring protein in the body.  Its normal role in a healthy organism is to trigger formation of new blood vessels (angiogenesis) supporting the growth of the body's tissues and organs. However, in certain diseases, such as wet age-related macular degeneration, it is also associated with the growth of abnormal new blood vessels in the eye, which exhibit abnormal increased permeability that leads to edema. Scarring and loss of fine-resolution central vision often results. In Central Retinal Vein Occlusion (CRVO), a blockage occurs in the main blood vessel that transports deoxygenated blood away from the retina.  VEGF levels are elevated in response contributing to macular edema.

EYLEA is a recombinant fusion protein, consisting of portions of human VEGF receptors 1 and 2 extracellular domains fused to the Fc portion of human IgG1 and formulated as an iso-osmotic solution for intravitreal administration.  EYLEA acts as a soluble decoy receptor that binds VEGF-A and placental growth factor (PlGF) and thereby can inhibit the binding and activation of these cognate VEGF receptors. EYLEA is specially purified and contains iso-osmotic buffer concentrations, allowing for injection into the eye.

In the United States, EYLEA is approved for the treatment of wet AMD and Macular Edema following CRVO.  Phase 3 trials are currently underway with EYLEA for the treatment of diabetic macular edema (DME) and Macular Edema following Branch Retinal Vein Occlusion (BRVO).  Bayer HealthCare plans to submit an application for marketing authorization in the CRVO indication in Europe towards the end of 2012.

IMPORTANT U.S. PRESCRIBING INFORMATION FOR EYLEA® (aflibercept) INJECTION

In the United States, EYLEA® (aflibercept) Injection is indicated for the treatment of patients with neovascular (Wet) Age-related Macular Degeneration (AMD).  The recommended dose for EYLEA is 2 mg administered by intravitreal injection every 4 weeks (monthly) for the first 12 weeks (3 months), followed by 2 mg once every 8 weeks (2 months). Although EYLEA may be dosed as frequently as 2 mg every 4 weeks (monthly), additional efficacy was not demonstrated when EYLEA was dosed every 4 weeks compared to every 8 weeks.

In the United States, EYLEA is also indicated for the treatment of patients with Macular Edema following Central Retinal Vein Occlusion (CRVO).  The recommended dose for EYLEA is 2 mg administered by intravitreal injection every 4 weeks (monthly).

IMPORTANT SAFETY INFORMATION FOR EYLEA® (aflibercept) INJECTION

EYLEA® (aflibercept) Injection 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.

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 during the post approval 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 use of intravitreal VEGF inhibitors, including EYLEA, defined as nonfatal stroke, nonfatal myocardial infarction, or vascular death (including deaths of unknown cause).  The incidence of ATEs in the VIEW 1 and VIEW 2 wet AMD studies in patients treated with EYLEA was 1.8% during the first year. The incidence of ATEs in the COPERNICUS and GALILEO CRVO studies was 0% in patients treated with EYLEA compared with 1.4% in patients receiving sham control during the first six months.

The most common adverse reactions (5% or more) reported in patients receiving EYLEA were conjunctival hemorrhage, eye pain, cataract, vitreous detachment, vitreous floaters, and increased intraocular pressure.

Serious adverse reactions related to the injection procedure have occurred in < 0.1% of intravitreal injections with EYLEA including endophthalmitis, traumatic cataract, increased intraocular pressure, and vitreous detachment.

About Wet AMD

Age-related macular degeneration (AMD) is a leading cause of acquired blindness.  Macular degeneration is diagnosed as either dry (non-exudative) or wet (exudative).  In wet AMD, new blood vessels grow beneath the retina and leak blood and fluid.  This leakage causes disruption and dysfunction of the retina creating blind spots in central vision, and it can account for blindness in wet AMD patients. Wet AMD is the leading cause of blindness for people over the age of 65 in the U.S. and Europe.

About Central Retinal Vein Occlusion

Over 100,000 people in the United States are estimated to suffer from CRVO.  CRVO is caused by obstruction of the central retinal vein that leads to a back up of blood and fluid in the retina.  This causes retinal damage and loss of vision.  Release of vascular endothelial growth factor (VEGF) contributes to increased vascular permeability in the eye and macular edema.  It is believed that anti-VEGF treatment may help decrease vascular permeability and edema in the retina in patients with CRVO.
