A Study of the Safety and Tolerability of ASP7317 in Senior Adults Who Are Losing Their Clear, Sharp Central Vision Due to Geographic Atrophy Secondary to Dry Age-related Macular Degeneration
Recruiting
Age-related macular degeneration (AMD) is an eye disease which causes people to lose their sharp central vision over time. Aging damages the macula, which is in the middle of the retina - the light-sensitive part at the back of the eye. There are 2 types of AMD - wet AMD and dry AMD. The advanced stage of dry AMD causes vision loss. This is known as geographic atrophy. AMD makes everyday tasks like reading or driving difficult. ASP7317 is a potential new treatment for people with AMD. ASP7317 a... Read More
