NCT ID NCT05338450

First seen May 11, 2026 · Last updated May 14, 2026 · Updated 2 times

Summary

This study tested whether clemastine fumarate, an antihistamine, could improve eye movement in people with multiple sclerosis (MS) who have a specific eye coordination problem called internuclear ophthalmoparesis (INO). The trial planned to enroll 80 adults with MS and INO, giving half clemastine and half a placebo for 6 months, then following them for 30 more months. The study was terminated early, so results are limited.
