New drug aims to shield vision during optic neuritis attacks

NCT ID NCT04762017

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This phase 2 trial tested a new drug called OCS-05 in 36 people with acute optic neuritis, a condition that inflames the optic nerve and can cause vision loss. Participants received OCS-05 or a placebo alongside standard steroid treatment for five days. The main goal was to check safety, and researchers also measured changes in retinal thickness to see if the drug might protect eye health.
