MS Patients' switch to ozanimod under the microscope
NCT ID NCT05658601
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 104 people with relapsing-remitting multiple sclerosis (RRMS) who switched their disease-modifying therapy to ozanimod. Researchers tracked why they switched (e.g., lack of effectiveness, side effects) and how the switch was done. The goal was to understand real-world use, not to test a new treatment.
