Is the new drug for ulcerative colitis Etrasimod-Velsipity?

In the field of treatment of ulcerative colitis, Etrasimod is an innovative drug recently approved internationally. Ulcerative colitis (UC) is a chronic inflammatory bowel disease with complex causes and is closely related to abnormal immune response. For a long time, treatments have mainly relied on aminosalicylic acid, glucocorticoids, immunosuppressants, and monoclonal antibody biological agents. However, these drugs either have serious side effects or require injections, and there are problems with long-term patient compliance. Therefore, the emergence of new oral small molecule drugs has become the focus of research and clinical practice in recent years.

Itramod belongs to the class of drugsS1P receptor modulators. It acts on the migration process of lymphocytes to reduce the entry of activated immune cells into the intestine, thereby reducing the inflammatory response. This mechanism is different from previous immunosuppression methods, thus bringing new hope to patients. In 2023, the US FDA approved itridimod for the treatment of moderate to severe ulcerative colitis. This is the most watched new drug launch event in this field in recent years. Since it is an oral preparation, it is more convenient to take and improves patient compliance during long-term treatment.

It should be pointed out that this drug is not currently on the market in mainland China, and patients may see relevant reports in international medical news or overseas drug databases and have questions. Therefore, patients in China still cannot directly obtain itrimod through formal channels. Whether it can be marketed in China in the future will depend on the progress of drug registration applications and the speed of submission of clinical trial data. At the same time, China continues to promote the research and development of therapeutic drugs for ulcerative colitis, including the introduction of new international drugs and the development of local innovative drugs.
