Study of new drugs for moderate to severe ulcerative colitis or Crohn's disease
This trial is testing multiple new drugs for people with moderate to severe ulcerative colitis or Crohn's disease who have not had success with at least one standard treatment. The goal is to find a better option that can help control symptoms and inflammation.
Scottsdale, ArizonaAges 18–80 - NCT07483099RecruitingPhase 2
Study of two drugs for Crohn's disease
This trial tests if taking a new drug (LY4395089) with mirikizumab works better than mirikizumab alone for adults with Crohn's disease. It also looks at the safety of these treatments.
Scottsdale, ArizonaAges 18–80 - NCT07481357RecruitingPhase 1
