Could a daily pill replace eye injections for diabetic macular edema?
NCT ID NCT06962839
First seen Jun 27, 2026 · Last updated Sep 04, 2026 · Updated 7 times
Summary
This study tests an oral medication called BI 1815368 in 300 adults with center-involved diabetic macular edema, a common cause of vision loss in diabetes. Participants take tablets twice daily for about 11 months, and doctors compare vision changes between those on the drug and those on placebo. The goal is to see if the pill can improve eyesight and find the best dose.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- BI 1815368 (oral tablet)
- What this could lead to
- If it works, this could provide a convenient oral treatment option for diabetic macular edema, potentially reducing the need for frequent eye injections.
- What could go wrong
- This is an early Phase 2 trial with a placebo group, so the drug may not improve vision or could cause side effects. Results may not apply to all patients.
