Promising drug cuts relapse risk in rare nerve disease
NCT ID NCT04201262
First seen Nov 01, 2025 · Last updated May 20, 2026 · Updated 25 times
Summary
This study tested a drug called ravulizumab in 58 adults with neuromyelitis optica spectrum disorder (NMOSD), a rare condition where the immune system attacks the nerves, causing vision loss and paralysis. The goal was to see if the drug could prevent relapses (new attacks). Participants received the drug and were compared to a placebo group from a previous study. Results showed fewer relapses in those taking ravulizumab, suggesting it may help control the disease.
