A Post-Authorization, Long-term Study of Ozanimod Real-world Safety

The purpose of this study is to determine the rates of adverse events of interest (AEIs) in a real-world population of participants with relapsing remitting multiple sclerosis (RRMS) receiving Ozanimod, sphingosine-1 phosphate (S1P) receptor modulator, compared to the rates of these events in two population of participants:

* Participants not exposed to ozanimod with RRMS who have received treatment with other S1P-receptor modulators disease modifying treatments (DMTs) * Participants not exposed to ozanimod with RRMS who have received treatment with other non-S1P-receptor modulators disease modifying treatments (DMTs)
