NCT ID NCT04526951

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This Phase 3 trial tested whether the clot-busting drug tenecteplase could improve vision in people with a central retinal artery occlusion (eye stroke). 81 participants received either tenecteplase or aspirin within 4.5 hours of symptoms. The main goal was to see if more patients in the tenecteplase group had significant vision improvement at 30 days.

Active substance

Tenecteplase (a clot-busting drug)

What this could lead to

If it works, this could provide a proven treatment to restore vision in people who have an 'eye stroke' (blocked artery in the eye).

What could go wrong

This is a small, completed Phase 3 trial (81 people). The drug carries a risk of bleeding, and results may not apply to all patients or be confirmed in larger studies.
