BI 1584862

This study is open to adults aged 55 years and older with geographic atrophy that was diagnosed by imaging of the retina. The purpose of this study is to find out whether a medicine called BI 1584862 improves the eyes in people with geographic atrophy and to find the most suitable dose.
This study has 4 treatment groups. Participants are put into groups randomly, which means by chance. Initially participants can join a BI 1584862 and a placebo group; then more participants are put randomly in 2 additional BI 1584862 groups and a placebo group.
Participants are in the study for 1 year. During this time, they visit the study site 13 times. At the visits, doctors check the severity of participants' eye disease and collect information on any health problems. They take detailed pictures of the back of the eye, the retina, with imaging methods called fundus autofluorescence (FAF) and optical coherence tomography (OCT). They measure areas of the retina that appear healthy (bright) or start to waste away (dark, atrophy). The changes over time are then compared between the treatment groups.
