NCT ID NCT07282574
First seen Jun 27, 2026 · Last updated Aug 18, 2026 · Updated 4 times
Summary
This study tests whether adding a new drug (RO7268489) to the standard MS treatment ocrelizumab can slow disability progression in adults with progressive multiple sclerosis. About 360 participants will receive either the new drug or a placebo, and researchers will track walking speed, hand function, and cognitive changes over time. The goal is to find a better way to manage this challenging form of MS.
