A clinical study of oral investigational medication for a type of advanced age-related macular degeneration (AMD)
(PIN: 37750)
This study is being done to see if a new investigational medicine can help adults with an advanced form of dry AMD called geographic atrophy (GA). GA is a progressive condition that can lead to blindness. There is currently no approved treatment for it.
Approximately 332 adults are being asked to join this study. You may be able to join if you have dry AMD in at least one eye and are 60 years or older.
There are other requirements. The study doctor will do tests to see if you meet the criteria and that the study is right for you.
