Abstract

Fingolimod functions as a modulator of sphingosine-1-phosphate (S1P) receptors expressed on the surface of T and B lymphocytes, leading to their internalization. Loss of S1P receptors results in sequestration of central memory T cells enriched by Th17 cells in lymph nodes. After successful treatment of an animal model of multiple sclerosis (MS), clinical trials of oral fingolimod in patients with relapsing-remitting MS showed a 60% reduction in the annualized rate of relapse. The United States Food and Drug Administration approved fingolimod as a first-line drug for MS treatment in 2010, and data have been accumulated thereafter. However, MS experts recommend that the drug should remain as a second-line option, because the long-term risks for infection and malignancy have not been fully elucidated. Also, because of different genetic backgrounds, Asian MS patients might require special attention regarding other infectious agents and secondary cancer as compared with those reported in Caucasian patients. Furthermore, some Japanese patients who developed severe symptoms were later shown to be positive for the anti-aquaporin-4 antibody. In addition, reports of some Western MS patients have noted worsening after initiation, as well as discontinuation of fingolimod treatment. Finally, the optic spinal type of MS and neuromyelitis optica spectrum disorders are more prevalent in Asian than Western countries. Thus, establishment of criteria for determining which Asian MS patients would benefit from fingolimod treatment is mandatory.
