Santen and Ube Industries Announce Launch of Glaucoma and Ocular Hypertension Treatment EYBELIS Ophthalmic Solution 0.002% in Japan

November 27, 2018

November 27, 2018 - Santen Pharmaceutical Co., Ltd. (Head Office: Osaka; hereinafter, “Santen”) and Ube Industries, Ltd. (Head Office: Ube; hereinafter, “Ube Industries”) announced today the launch of glaucoma and ocular hypertension treatment EYBELIS Ophthalmic Solution 0.002% (JAN*: Omidenepag Isopropyl; hereinafter, “EYBELIS”) in Japan.

Santen and Ube Industries co-developed EYBELIS as a treatment for glaucoma and ocular hypertension. Omidenepag Isopropyl, the active pharmaceutical ingredient in EYBELIS, is the world’s first selective EP2 receptor agonist and is an ocular hypotensive agent with a new mechanism of action.

Glaucoma is a disorder which causes optic nerve damage leading to visual field loss, and is a major cause of visual impairment including decreased vision and blindness in Japan. Since glaucomatous optic nerve damage and visual field defects are generally progressive and irreversible, early detection and treatment for controlling progression of damage is crucial in the treatment of glaucoma. EYBELIS is shown to contribute to the lowering of intraocular pressure (IOP), the most effective means of avoiding glaucomatous damage.

Director, Executive Corporate Officer of Japan Business, and head of Japan Sales and Marketing, Prescription Pharmaceuticals Takeshi Ito of Santen says, “EYBELIS is an eye drop treatment based on a world-first mechanism of action and research has verified the non-inferior IOP-lowering effect of EYBELIS ophthalmic solution 0.002% against latanoprost ophthalmic solution 0.005%. EYBELIS is an ophthalmic solution that has the potential to become a first-line treatment using a new mechanism of action, and I am expecting this product will meet unmet needs that exist in current glaucoma therapies. Santen aims at further helping patients by providing appropriate drug information and leveraging the strengths we have nurtured in ophthalmology and our Japan business in particular.”

Executive Officer, General Manager of Pharmaceutical Division Yasushi Konno of Ube also mentions, “Ube is engaged in producing a new drug form our region with abundant technical innovation and aims to contribute to better health for everyone. Omidenepag Isopropyl is the outcome of our efforts in medicinal chemistry and CMC technology, which we have cultivated for many years. To further contribute to health care, we will continue discovering and developing new chemical entities that can be seeds for new medicinal products.”

Santen and Ube Industries will make EYBELIS available in medical settings as a new treatment option, and will provide drug safety information for patients and healthcare professionals, in order to promote understanding of the appropriate use of EYBELIS, thereby enhancing patients' quality of life.

Santen and Ube have no plans to revise their full-year financial forecasts as a result of this announcement.
