Summary
This trial is open to adults with moderate or high severity non-proliferative diabetic retinopathy. The purpose of the study is to see if a medicine called BI 764524 can help people
Who is the study for?
Adults with moderate to severe non-proliferative diabetic retinopathy can join this study. They must have diabetes under control (HbA1c <12%), clear eyes, and good enough vision (20/100 or better). People are excluded if they don't meet these eye health and diabetes management criteria.
What is being tested?
The trial is testing BI 764524 for diabetic retinopathy. Participants are randomly assigned to one of five groups: three receive varying numbers of BI 764524 injections, one receives sham injections, and the last group (US only) gets Aflibercept or sham treatments.
What are the potential side effects?
Potential side effects aren't specified here but may include typical injection-related reactions such as eye irritation, discomfort, redness, or infection. Systemic side effects could also occur depending on the medication's profile.

Study Objectives
Outcome measures can provide a clearer picture of what you can expect from a treatment.Primary outcome measures
Occurrence of a ≥2-step improvement compared with baseline in Diabetic Retinopathy Severity Scale (DRSS) level in the study eye at Week 52
Secondary outcome measures
Absolute change from baseline of best corrected visual acuity (BCVA) [early treatment diabetic retinopathy study (ETDRS) letters] in the study eye at Week 52
Absolute change from baseline of central retinal thickness [μm], as assessed by spectral domain optical coherence tomography (SD-OCT), in the study eye at Week 52
Occurrence of a ≥2-step worsening of Diabetic Retinopathy Severity Scale (DRSS) in the study eye between baseline and Week 52
