Study Summary

This is a study in people with a type of diabetic eye disease called diabetic retinopathy with diabetic macular ischemia. People who have had laser treatment for their diabetic retinopathy can participate in the study. The laser treatment is called panretinal photocoagulation. The purpose of the study is to find out how well different doses of a medicine called BI 764524 are tolerated. BI 764524 is injected into the eye. The study has 2 parts. In the first part, participants get different doses of BI 764524 only once. Participants are in the first part for about 5 months and visit the study site about 8 times. In the second part, participants are put into different groups by chance. Some participants get BI 764524 injections every 4 weeks. Other participants get sham injections every 4 weeks. A sham injection means that it is not a real injection and contains no medicine. Participants cannot tell whether they get the real injection or a sham injection. For the second part, participants are in the study for about 7 months. During this time, they visit the study site about 7 times. In this study, BI 764524 is given to humans for the first time. The doctors compare how well people tolerate the BI 764524 injections and the sham injections. The doctors also regularly check the general health of the participants.

Primary Outcome
