Ozanimod vs. fingolimod: is there a difference?


A new analysis suggests that ozanimod (Zeposia) may have a better safety profile than fingolimod despite being similar agents (Swallow et al. J Comp Eff Res 2020;9:275-285). Both drugs are sphingosine-1-phosphate (S1P) receptor agonists that act as functional antagonists, sequestering T cells in secondary lymphoid organs. Fingolimod acts on S1PR-1,3,4,5, whereas ozanimod (like siponimod) is selective to S1PR1,5. Ozanimod was approved in Canada for the treatment of relapsing MS in October 2020.

Monies paid are to ensure a supply of vaccine and will not be fully refunded if the vaccines are ineffective or fail to receive Health Canada approval (Canadian Press, 22 September 2020).
