Ozanimod: A Review in Relapsing Forms of Multiple Sclerosis.

Ozanimod (Zeposia), an orally administered sphingosine 1-phosphate (S1P) receptor modulator (S1PRM) that is selective for the S1P and S1P receptor subtypes, is approved in the USA for relapsing forms of multiple sclerosis (RMS). In pivotal phase III clinical trials in patients with RMS, ozanimod significantly reduced annualised relapse rates and the number of new or enlarging T2 lesions and gadolinium-enhancing lesions, and was associated with reduced brain volume loss, compared with interferon (IFN)-β1a. However, there were no significant differences in 3- and 6-month disability progression between the groups. Ozanimod was generally well tolerated, with the most common adverse reactions including upper respiratory tract infection and hepatic transaminase elevation. Efficacy and tolerability were sustained over more than 6 years with continued treatment. S1PRM-related adverse events seen with ozanimod are generally manageable with screening and/or monitoring. Notably, ozanimod does not require first-dose cardiac monitoring in the USA. In conclusion, ozanimod is a valuable once-daily oral disease-modifying therapy that extends the available treatment options for patients with RMS.
