Mirikizumab belongs to the class of medications called monoclonal antibodies. Monoclonal antibodies recognize specific proteins in the body and stop them from working.

Specifically, mirikizumab is an interleukin-23 antagonist. It is used for the treatment of adults with moderately to severely active ulcerative colitis or Crohn's disease when there has been a poor response to other treatments, or these treatments are no longer effective or have unacceptable side effects.

Ulcerative colitis is a disease in which the large bowel becomes inflamed, resulting in symptoms such as abdominal pain and cramping, diarrhea, rectal pain, and rectal bleeding. Crohn's disease is a disease where there is chronic inflammation of the gastrointestinal tract, which can be caused by the protein interleukin-23 (IL-23). This medication works to reduce the activity of IL-23.
