TARRYTOWN, N.Y., March 3, 2014 /PRNewswire/ -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that Bayer HealthCare's Japanese subsidiary, Bayer Yakuhin, Ltd., has submitted an application for marketing authorization for EYLEA^® (aflibercept) Injection for the treatment of patients with diabetic macular edema (DME) to the Japanese Ministry of Health, Labour and Welfare (MHLW).

"Clinically significant DME is a leading cause of vision loss in the working-age population suffering from diabetes.  With increasing rates of diabetes worldwide, there continues to be a need for new treatment options," said George D. Yancopoulos, M.D., Ph. D., Chief Scientific Officer of Regeneron and President of Regeneron Laboratories.  "We are pleased with this regulatory submission and hope that if approved, EYLEA will provide a new option for the treatment of DME in Japan."  

The submission of EYLEA for DME in Japan is based on data from the VISTA-DME, VIVID-DME and VIVID-Japan studies.  In the Phase 3 VIVID-DME and VISTA-DME trials, EYLEA 2 milligrams (mg) dosed monthly and EYLEA 2 mg dosed every two months (after 5 initial monthly injections) achieved the primary endpoint of significantly greater improvement in best-corrected visual acuity (BCVA) from baseline compared to laser photocoagulation at 52 weeks.  In these trials, EYLEA was generally well tolerated with a similar overall incidence of adverse events (AEs), ocular serious AEs, and non-ocular serious AEs across the treatment groups and the laser control group.  Arterial thromboembolic events as defined by the Anti-Platelet Trialists' Collaboration (non-fatal stroke, non-fatal myocardial infarction, and vascular death) also occurred at similar rates across the treatment groups and the laser control group.  The most frequent ocular treatment emergent AEs (TEAEs) observed in the VIVID-DME and VISTA-DME trials included conjunctival hemorrhage, eye pain, and vitreous floaters.  The most frequent non-ocular TEAEs included hypertension and nasopharyngitis, which occurred with similar frequency in the treatment groups and the laser control group.

One-year data from the VIVID-DME and VISTA-DME trials have been presented at medical congresses in the U.S. and Europe.  Full two-year data from the VISTA-DME trial will be presented at upcoming medical conferences.  Two-year data from the similarly designed VIVID-DME trial are expected later in 2014.  Each of the VISTA-DME and the VIVID-DME trials is expected to continue as planned up to 148 weeks.

EYLEA was approved in the United States for the treatment of neovascular (wet) Age-related Macular Degeneration (AMD) in November 2011 and for Macular Edema following Central Retinal Vein Occlusion (CRVO) in September 2012.  EYLEA has also been approved in the European Union (EU) and other countries for use in wet AMD and Macular Edema following CRVO.  Regulatory submissions have also been made in the U.S. and the EU for EYLEA for the treatment of DME.  A regulatory submission has been made in the U.S. for EYLEA for the treatment of macular edema following Branch Retinal Vein Occlusion (BRVO).

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

About the EYLEA^® (aflibercept) Injection Phase 3 DME Program
The global Phase 3 DME program consists of three double-masked trials: VIVID-DME, VISTA-DME, and VIVID-EAST-DME, and one open-label, single-arm safety trial in Japanese patients (VIVID-Japan).  All three double-masked studies have three treatment arms, where patients are randomized to receive either EYLEA 2 mg monthly, EYLEA 2 mg every two months (after 5 initial monthly injections), or the comparator treatment of laser photocoagulation.  Based on protocol specified criteria, patients were eligible to receive rescue treatment from week 24 onwards.  Rescue treatment in the EYLEA groups was adjunct laser treatment, and in the laser control group it was EYLEA 2 mg.  The primary efficacy endpoint of all three studies is the mean change in BCVA from baseline, as measured on the Early Treatment Diabetic Retinopathy Scale (ETDRS) eye chart, a standard chart used in research to measure visual acuity.  The VIVID-DME, VISTA-DME, and VIVID-EAST-DME studies are ongoing.

About Diabetic Macular Edema (DME)
DME is a common complication of Diabetic Retinopathy, a disease affecting the blood vessels of the retina.  Clinically significant DME occurs when fluid leaks into the center of the macula, the light-sensitive part of the retina responsible for sharp, direct vision.  Fluid in the macula can cause severe vision loss or blindness.

DME is the most frequent cause of blindness in young and mid-aged adults.  The treatable population for DME globally is estimated at about 6.2 million people.  According to the American Diabetes Association, over 18 million Americans currently suffer from diabetes, and many more are at risk for developing diabetes.  The incidence of diabetes has been steadily climbing and it is projected that up to seven percent of all patients with diabetes will develop DME during their lifetime.

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.

EYLEA, known in the scientific literature as VEGF Trap-Eye, 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 their cognate VEGF receptors. 

IMPORTANT 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.

EYLEA is 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 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 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) noted in the U.S. prescribing information for the approved indications of 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 &#60 0.1% of intravitreal injections with EYLEA including endophthalmitis, traumatic cataract, increased intraocular pressure, and vitreous detachment.
