NCT ID NCT04577300
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This phase 2 trial tests whether an implant placed in the eye can slow vision loss in people with glaucoma. The implant releases a protein that may protect nerve cells. Thirty participants will receive either the real implant or a sham procedure and be followed for two years.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
NT-501 encapsulated cell therapy implant (releases ciliary neurotrophic factor)
What this could lead to
If it works, this could point toward a new way to slow vision loss in glaucoma by protecting nerve cells in the eye.
What could go wrong
This is a small, early-phase trial with only 30 people, so results may not apply to everyone. The implant requires surgery and may cause side effects like infection or inflammation.
