TARRYTOWN, N.Y., Nov. 22, 2013

TARRYTOWN, N.Y., Nov. 22, 2013 /PRNewswire/ --Regeneron Pharmaceuticals, Inc.
(NASDAQ: REGN) today announced that EYLEA^® (aflibercept) Injection has
received approval for the treatment of Macular Edema Following Central Retinal
Vein Occlusion (CRVO) from the Japanese Ministry of Health, Labour and

"We are pleased with the approval of EYLEA in Japan in the macular edema
following CRVO indication, a significant cause of visual impairment in
adults," said George D. Yancopoulos, M.D., Ph. D., Chief Scientific Officer of
Regeneron and President of Regeneron Laboratories. "This approval reflects
our commitment, along with our partner Bayer HealthCare, to bring EYLEA to
patients worldwide."

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), 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 following CRVO, as well as in selected countries in Asia and Latin
America. Regulatory submissions have also been made in the U.S. and the EU
for EYLEA in Diabetic Macular Edema.

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 Central Retinal Vein Occlusion (CRVO)
Over 66,000 people in major European countries, more than 100,000 people in
the United States, and about 140,000 patients in Japan, over the age of 40 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 has been shown that anti-VEGF treatment may help
decrease vascular permeability and edema in the retina in patients with CRVO.

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, 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, 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


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).


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.
