Etrasimod is a novel sphingosine-1-phosphate receptor modulator, first approved for marketing by the U.S. Food and Drug Administration (FDA) in 2023. As an oral medication for the treatment of moderately to severely active ulcerative colitis, etrasimod provides a new therapeutic option for patients with this chronic inflammatory bowel disease.
Indications of Etrasimod
Main Therapeutic Area
Clinical studies have confirmed that etrasimod is specifically indicated for the treatment of moderately to severely active ulcerative colitis in adults.
Ulcerative colitis is a chronic, non-specific inflammatory bowel disease that primarily affects the colonic mucosa and submucosa. Its clinical manifestations include symptoms such as diarrhea, mucopurulent bloody stools, and abdominal pain.
Etrasimod exerts its effects by regulating the immune system, which can effectively control disease activity and improve patients’ symptoms.
Characteristics of Eligible Populations
This medication is indicated for adult patient populations and has demonstrated efficacy in patients with moderate to severe active disease in clinical trials.
It is important to note that etrasimod is not indicated for patients with mild ulcerative colitis, nor is it suitable for pediatric patient populations.
