New eye drops show promise for healing corneal damage

NCT ID NCT04909450

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested an experimental eye drop called CSB-001 in 131 people with neurotrophic keratitis, a rare condition where the cornea loses sensation and can develop ulcers. Participants used the drops four times daily for 8 weeks. The goal was to see if the drops could fully heal the cornea better than a placebo.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
CSB-001 ophthalmic solution (a growth factor protein)
What this could lead to
If it works, this could lead to a new treatment that helps heal corneal damage in people with neurotrophic keratitis.
What could go wrong
This is an early-phase trial with only 131 people, so results may not hold up in larger studies. The condition is rare, and the treatment may not work for everyone.
