Santen entered into a strategic alliance with Plano Pte. Ltd (hereinafter, "Plano") to tackle the global burden of myopia in June 2020. Plano, an eye health tech startup, is widely recognized as one of the world leaders in public awareness-raising and education on the prevention and risks of myopia.
Through Plano, Santen is promoting education and prevention efforts to protect children's eyes from myopia in Singapore, and is beginning to roll out this innovative solution in China and Asia.
Santen is working closely with Plano to resolve social issues related to myopia and to improve the quality of life of the patients around the world.
Contribution to Ophthalmology
Santen will make efforts to pursue healthy eyes and access to medicine so as to reduce the number of untreated patients by contributing to healthcare in ophthalmology, which is our business field.
Pursuing Healthy Eyes and Contributing to the Ophthalmology
We will contribute to reducing the number of untreated patients worldwide by developing products with social significance and improving access to ophthalmic treatment for more and more people. We aim to contribute to more than 50 million patients(*1) by 2025. We have contributed around 48 million patients in FY2020 and 50 million patients in FY2021.
- Estimated total no. of patients to which Santen contributed (disease areas: inflammation/allergies, cornea, glaucoma, cataracts) in FY2019 was approx. 43 million, calculated based on JMDC's estimated total no. of patients for Santen's Rx products and Santen's shipment data, target was revised when the new medium-term management plan was formulated.

Activities to Prevent Vision Loss due to Glaucoma
Introducing a glaucoma treatment continuation program
Glaucoma is the leading cause of vision loss in Japan. One of the challenges concerning glaucoma is that many patients with this almost symptomless disease discontinue their medical treatment. As an initiative to encourage glaucoma patients to continue to receive medical treatment, Santen has developed ACT Pack®, a glaucoma treatment adherence program. This program has so far been provided to and utilized by more than 2,000 medical institutions. A report(*) says that the introduction of ACT Pack® increased the six-month adherence rate from 42.1% to 94.2%.
We will expand this initiative to other countries outside of Japan, mainly in Asia.
- Report on an increase in the six-month adherence rate from a level before the introduction of 42.1% to 94.2%: Tanaka, Toshihiro et al. (2020), Ganka, 62 (8): 801-807
Offering support for awareness-raising activities for early detection
The World Glaucoma Association and the World Glaucoma Patients Association play leading roles in performing various knowledge-sharing activities around the world for one week in March designated as the World Glaucoma Week (WGW), aiming to build public awareness of glaucoma. Santen cosponsors worldwide activities for raising awareness of glaucoma. In 2023, although the impact of COVID-19 continues, Santen supported the following activities in Asia, Europe, Japan and others, in collaboration with ophthalmologists from glaucoma societies in various countries, for early detection of glaucoma.
- Japan: Held "Light-up in Green!" events associated with glaucoma, and issued Santen-produced manga advocating about the disease.
- Asia: In addition to public education activities, coordinated with hospitals across multiple countries, and promoted early detection and proper management of glaucoma, emphasizing the need for regular screening and continuous treatment.
- China: Under the guidance of Shanghai Municipal Health Commission, the Shanghai Eye Disease Prevention and Treatment Center (Shanghai Eye Hospital) was joined by Shanghai Municipal Center for Health Promotion and many other institutions in both online and offline activities focused on playing a role in protecting people's vision and light.
- U.S.: To increase awareness of glaucoma and to educate patients, advocated its importance through social media starting from January, which is U.S. Glaucoma Awareness Month.

Campaigns to Raise Public Awareness of Dry Eye Syndrome and Promote Continuous Dry Eye Treatment
Dry eye is a modern-day disease whose concept was introduced to Japan around 1985. The number of potential patients with dry eye disease is estimated at 8 to 22 million in Japan. Of those only around 2 million are estimated to receive treatment prescribed by a doctor. The Santen Group aims to contribute to as many dry eye syndrome patients as possible by providing potential dry eye patients with the opportunities to accurately know and understand the disease and encouraging them to consult eye doctors and receive ophthalmic treatment. To accomplish the aim, we have continued to run campaigns to raise public awareness of dry eye syndrome, by sharing a wide range of information, and other means.
In addition, we recognize that, despite its expected effectiveness, continuous dry eye treatment involves some challenges. The challenges faced by doctors include the effort and experience required to correctly diagnose dry eye and the difficulty in giving thorough explanations to patients while busily performing their daily medical duties. The challenges faced by patients include the difficulty in recognizing the current state and improvements of their own eyes, which can demotivate them and, as a common consequence, lead them to discontinue receiving medical treatment. To help solve these challenges, Santen developed TEARMIRU®, a dry eye treatment support system, which is expected to increase patient satisfaction in treatment, and launched it for sale in April 2023. This system enables patients to visually understand the current state of their own eyes and recognize improvements and the effects of treatment on their symptoms. Moreover, explanations given in the system about the subtype of dry eye they suffer from are expected to help patients understand the purpose of treatment and consequently increase their motivation to continue to receive dry eye treatment.

Improving Access to Healthcare in Accordance with the Characteristics of Local Communities
We recognize poor access to health and medical care in many emerging countries as a serious issue to be solved. In such countries, a shortage of ophthalmologists and other professionals related to ophthalmic treatment has prevented patients from receiving adequate medical treatment or even being correctly diagnosed. In addition, a shortage of medical technicians involved in examinations has forced ophthalmologists to conduct even basic examinations on their own, resulting in a general decrease in productivity. To enable such ophthalmologists to increase their skills in cataract surgery and glaucoma treatment and spend more time treating their patients, Santen works with external partners to offer training systems and medical information to ophthalmologists. Moreover, we also devote serious efforts to educating medical examination staff, who provide doctors with valuable support. We therefore aim to improve medical access in emerging countries.
Initiatives to Combat Rare Diseases
Development and research for orphan drugs sometimes suffer delays because of the very small number of patients, despite their very serious need for this kind of drug. Santen is also strongly committed to improving medical access for patients suffering from rare diseases in the ophthalmic field.
Verkazia, a vernal keratoconjunctivitis (VKC) treatment
Vernal keratoconjunctivitis (VKC) is a recurrent serious allergic eye condition, most common in children and adolescents, characterized by severe inflammation of the ocular surface, including corneas and conjunctivas. Its symptoms include intense eye itching, eye pain, and high light sensitivity, which can hinder the daily lives of patients. Without adequate treatment, severe cases may cause corneal ulcers and visual impairments.
Santen has developed and been marketing Verkazia, a cyclosporine ophthalmic emulsion for VKC, which features a long-time stay on the ocular surface and improved corneal absorption based on Santen's proprietary cationic nanoemulsion technology.
As of June 2023, Santen has obtained approval for Verkazia in more than 10 countries in the Americas, Asia, including China, and other regions. To remove the limitations imposed by VKC on the activities of young patients around the world and help them return to as comfortable a daily life as possible, we are doing our best to facilitate the supply of this product.
jCell, a Cell Therapy Targeting Retinitis Pigmentosa
Retinitis pigmentosa, a disease caused by genetic mutations, causes wide-ranging degeneration of retinal photoreceptor cells and retinal pigment epithelial cells. Characteristic symptoms caused by the condition include night blindness, narrowing of the visual field, and decreased visual acuity. It often strikes people in their teens, with many patients rendered blind by middle age. Worldwide, approximately 1.9 million patients suffer from the disease(*1). In Japan, estimates suggest 18.7 people per 100,000 of population have the condition(*2). Retinitis pigmentosa has a wide impact on everyday life as it affects any operation requiring vision including movement and learning. There are currently very few treatments available for retinitis pigmentosa, with no treatments being available for all forms of the diseases, irrespective of the underlying genetic cause. Therefore, this is an area of significant unmet medical need.
As part of its efforts to unlock the power of cell and gene therapies to address high unmet medical needs in ophthalmology, Santen has concluded an exclusive licensing agreement with U.S.-based jCyte for the rights to develop and market jCell, an investigational cell therapy with the potential to be a first-in-class, gene-agnostic treatment for retinitis pigmentosa. jCell has been granted Regenerative Medicine Advanced Therapy (RMAT) by the U.S. Food and Drug Administration (FDA) based on early clinical data, and has also received Orphan Drug designation from both the FDA and the European Medicines Agency (EMA).
