MS patients on ozanimod: how long does treatment last?
NCT ID NCT05811416
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows about 200 people with relapsing-remitting multiple sclerosis (RRMS) who are starting ozanimod (Zeposia®) for the first time. Researchers want to see how long patients continue the medication in everyday practice and how well it controls their disease. The study does not test a new drug—it simply observes real-world use and outcomes over 24 months.
