Stem cell eye treatment could restore sight in retinal disease patients

NCT ID NCT06789445

First seen Jun 24, 2026 · Last updated Jul 07, 2026 · Updated 3 times

Summary

This study tests a new treatment called OpCT-001 for people with inherited eye diseases that damage the retina, such as retinitis pigmentosa. The treatment involves injecting special photoreceptor cells, made from stem cells, into the back of the eye to replace lost cells. The trial will enroll 54 adults and first check safety, then see if it improves vision.

What this could mean

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

Active substance
OpCT-001 (photoreceptor precursor cells made from stem cells)
What this could lead to
If it works, this could slow or reverse vision loss in people with inherited retinal diseases, potentially restoring some sight.
What could go wrong
This is an early, first-in-human trial with only 54 people. The cells may not survive or integrate, and there are risks from surgery and immune reactions.
