Intravitreal VEGF Inhibitor EYLEA approved as a Treatment of Neovascular Glaucoma (NVG), its fifth indication

Osaka, March 25, 2020 - Bayer Yakuhin, Ltd. (Osaka, hereinafter Bayer Yakuhin) and Santen Pharmaceutical Co., Ltd. (Osaka, hereinafter Santen) announced today that Bayer Yakuhin has received approval for the additional indication of "neovascular glaucoma (NVG)" for the intravitreal VEGF* inhibitor EYLEA® solution for intravitreal injection 40 mg/mL (aflibercept [genetical recombination], hereinafter EYLEA®) and EYLEA® intravitreal injection KIT 40 mg/mL, pre-filled syringe to administer EYLEA® (hereinafter EYLEA® pre-filled syringe). Orphan Drug Designation has been granted for this indication. * VEGF = vascular endothelial growth factor

EYLEA® vial and EYLEA® pre-filled syringe have received approvals for age-related macular degeneration with subfoveal choroidal neovascularization, macular edema secondary to retinal vein occlusion, choroidal neovascularization in pathologic myopia and diabetic macular edema. This approval is the fifth indication EYLEA® obtained.

NVG is a secondary glaucoma in which new blood vessels are formed in the iris and the anterior chamber angle. The outflow of aqueous humor is inhibited and, intraocular pressure is increased. NVG is a serious complication mainly in diseases causing retinal ischemia such as proliferative diabetic retinopathy and central retinal vein occlusion. There remains a high unmet medical need as progressive disease is likely to lead to blindness.

Dr. Masaru Inatani, Professor at Department of Ophthalmology, Faculty of Medical Sciences, University of Fukui said, "NVG is an intractable glaucoma that tends to lead to blindness, so it demands urgent treatment. Up to this point, there wasn't any approved treatment directly acting on VEGF, a major cause of neovascularization, to regress new blood vessels and reduce intraocular pressure. EYLEA®'s approval for use in Japan for NVG, the first in the world, presents a new treatment option for patients in Japan. The clinical use of EYLEA®, which is expected to reduce intraocular pressure, is anticipated to be beneficial not only to patients but also to healthcare professionals."

Santen is responsible for distributing EYLEA® in Japan, while Bayer Yakuhin holds the marketing authorization for the product. Both companies jointly conduct detailing activities at medical institutions and provide information about the product to medical professionals.

EYLEA® pre-filled syringe is currently under preparation for the launch.

About VEGA study and VENERA study

This approval is based on the data from two Phase III studies: the randomized, double-blind, controlled VEGA study, and the open-label, single-arm VENERA study to investigate the efficacy, safety, and tolerability of intravitreal EYLEA® in Japanese patients with NVG. Taken together, both studies showed efficacy of EYLEA® as assessed by the change from baseline in intraocular pressure at Week 1 as the primary endpoint and the proportion of subjects with improvement from baseline in the grade of neovascularization of iris (NVI) at Week 1 as the secondary endpoint. Also, adverse event findings during both studies were consistent with the known safety profile for EYLEA®.

About VEGF and EYLEA® (aflibercept solution for injection into the eye) 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. It is also associated with the growth of abnormal new blood vessels in the eye, which exhibit abnormal increased permeability that leads to 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 (PGF) and thereby can inhibit the binding and activation of their cognate VEGF receptors.

Bayer and Regeneron Pharmaceuticals, Inc. are collaborating on the global development of EYLEA®. Regeneron maintains exclusive rights to EYLEA® in the U.S. Bayer has licensed the exclusive marketing rights outside the U.S., where the companies share equally the profits from sales of EYLEA®, except for Japan where Regeneron receives a percentage of net sales.
