Princeton, NJ and TOKYO, April 2, 2024 - Kyowa Kirin Co., Ltd. (TSE: 4151) a Japan-based global specialty pharmaceutical company (J-GSP) creating innovative medical solutions utilizing the latest biotechnology, today announced that pre-clinical data of tivozanib (KHK-4951), an investigational product, assessing the ocular pharmacokinetics of a novel tivozanib eye drop for neovascular age-related macular degeneration (nAMD), will be presented at the upcoming Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting to be held in Seattle, Washington from May 5-9, 2024.

Age-related macular degeneration (AMD) is a leading cause of severe vision loss and blindness for people aged 60 years and older in developed countries worldwide, with a profound impact on the quality of life of affected individuals. With the increase in life expectancy, the number of reported cases of AMD is increasing. The disease and its current treatment regimen add significant burden on patients, caretakers, and on health care system.

Neovascular (wet) AMD (nAMD) is characterized by abrupt central vision loss caused by abnormal blood vessel growth in the macular area, the part of the retina that is responsible for everyday activities such as reading, driving, and writing. These vessels are fragile, leak fluid, can easily break and cause bleeding. nAMD accounts for roughly 10% of all AMD cases, but almost 90% of AMD-related central vision loss.
