A Master Protocol (IIBD): A Study of Multiple Drugs in Adults With Ulcerative Colitis or Crohn's Disease

What this study is about

Study IIBD is a master protocol that will support a collection of individual sub studies that share key design components. Participants will be assigned to the appropriate study prior to randomization to a treatment group. The studies aim to evaluate the efficacy and safety of new treatments in adults with moderately to severely active ulcerative colitis or Crohn's disease and will last at least 62 weeks.

• For CD:
  • Have moderately to severely active CD as defined by a Crohn's disease activity index (CDAI) score ≥ 220 and less than or equal to (≤) 450. Have a centrally read Simple Endoscopic Score for Crohn's Disease (SES-CD) score ≥6 for participants with ileal-colonic or ≥4 for participants with isolated ileal disease within 21 days before the randomization
