A study to evaluate etrolizumab as a treatment for patients with moderate to severe ulcerative colitis who are naive to TNF inhibitors.

Currently recruiting

About this study

The purpose of this study is to determine whether etrolizumab is:

  • A safe and effective treatment in patients with moderate to severe active ulcerative colitis that have previously had an unsuccessful response to treatment with immunosuppressants (also known as TNF inhibitors – medications that reduces the activation or efficacy of the immune system) such as azathioprine, 6-mercaptopurine, or methotrexate and/or corticosteroids
  • More effective than adalimumab in treating ulcerative colitis

Adalimumab is approved by the Therapeutic Goods Administration in Australia for use in ulcerative colitis.

Anticipated enrolment close date: Ongoing
