NCT ID NCT06952842

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a gene therapy called ZVS203e for people with retinitis pigmentosa caused by a specific RHO gene mutation. The therapy is injected into the eye and uses a harmless virus to deliver a gene-editing tool. The trial includes 18 adults and will check safety and whether it improves vision over 24 weeks.

What this could mean

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

Active substance

ZVS203e (a gene therapy using a harmless virus to deliver a gene-editing tool into the eye)

What this could lead to

If successful, this could slow or partially reverse vision loss in people with a specific genetic form of retinitis pigmentosa.

What could go wrong

This is an early-phase trial with only 18 participants, so results may not apply to everyone. Gene therapies can cause inflammation or other side effects, and vision improvement may be limited or temporary.
