TARRYTOWN, N.Y., Nov. 7, 2013

TARRYTOWN, N.Y., Nov. 7, 2013 /PRNewswire/ --Regeneron Pharmaceuticals, Inc.
(NASDAQ: REGN) and Bayer HealthCare today announced that  Bayer HealthCare has
submitted an application for marketing authorization in the European Union
(EU) for EYLEA^® (aflibercept) Injection for the treatment of patients with
Diabetic Macular Edema (DME). Regeneron has submitted a supplemental BLA for
EYLEA in this indication to the U.S. Food and Drug Administration (FDA).

"Diabetes is a growing, worldwide health concern and DME is a major cause of
vision loss in those with diabetic retinopathy," 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 in a third
indication for EYLEA in Europe and, if approved, hope to be able to offer
physicians and patients a new treatment option."

The submission of EYLEA for DME is based on data from the positive Phase 3
VISTA-DME and VIVID-DME studies. One-year data from both trials have been
presented at medical conferences. The VISTA-DME and VIVID-DME trials are
planned to continue 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, Japan, Australia, and in several
other countries for use in wet AMD. EYLEA has also been approved by the
European Commission for the treatment of visual impairment due to macular
edema secondary to CRVO, as well as in selected countries in Asia and Latin
America.

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 royalty on net sales.

About the EYLEA^® (aflibercept) Injection Phase 3 DME Program
The Phase 3 DME program consists of three double-masked trials: VIVID-DME,
VISTA-DME, and VIVID-EAST-DME (in Russia, China and other Asian countries),
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 milligrams (mg)
monthly, EYLEA 2 mg every two months (after 5 initial monthly injections), or
the comparator treatment of laser photocoagulation. The primary endpoint of
all three studies is the mean change in best-corrected visual acuity 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 (DR), 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.
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 is 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. In patients with diabetic macular edema (DME),
hyperglycemia-induced vascular dysfunction and hypoxia result in elevated
intraocular VEGF levels in the eye and resultant blood vessel permeability
that leads to macular edema, which can result in vision loss.

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
<0.1% of intravitreal injections with EYLEA including endophthalmitis,
traumatic cataract, increased intraocular pressure, and vitreous detachment.
