Beskrivelse
Key Inclusion Criteria:
- Diagnosis of RRMS.
- Continuous treatment with natalizumab of ≥24 months. In case of a treatment interruption from natalizumab ≥60 days after a total treatment period of ≥24 months, only the treatment prior to the interruption will be analyzed. Any data after this treatment interruption (even if the patient restarts natalizumab) will not be analyzed/collected.
- ≥1 MRI scan of sufficient quality for reliable measurement.
- Baseline MRI scan ≤6 month prior to natalizumab treatment acquired.
- ≥1 MRI scan of sufficient quality for reliable measurement taken while on natalizumab treatment for ≥6 months.
- EDSS ≤ 6.5.
Key Exclusion Criteria:
- Anti-natalizumab antibody detection.
- Prior treatment with alemtuzumab.
- Prior treatment with mitoxantrone within 12 months of the first infusion of natalizumab.
NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
