About this study

The purpose of this study is to assess the efficacy and safety of Etrasimod in participants with moderately active ulcerative colitis (UC).

Etrasimod is designed to block the movement of some kind of cells in your body (part of your immune system called lymphocytes) to areas of inflammation in the colon.

Etrasimod is an experimental treatment. This means that it is not approved treatment for UC by Regulatory Authorities such as the Therapeutic Goods Administration (TGA) in Australia and the Food and Drug Administration (FDA) in the United States.

Anticipated enrolment close date: 31 December 2026
