Treatment of moderate to severe UC
Etrasimod (Arena Pharma/Pfizer) is an oral sphingosine-1-phosphate (S1P) receptor that binds with high affinity to receptors 1, 4, and 5. If approved by the FDA, etrasimod could become the second agent in the S1P class approved for ulcerative colitis in the United States. The other agent, ozanimod (Zeposia), received FDA approval for treating moderately to severely active UC in May 2021. [1]
