Brief summary
This is a Phase 2, multicenter, platform study in adult participants with IBD (moderately to severely active Crohn's Disease or Ulcerative Colitis). The primary goal of this study is to assess the safety and efficacy of multiple investigational drugs.
Detailed description
The purpose of this platform study is to assess the safety, efficacy, pharmacokinetics (PK), and pharmacodynamics (PD) to evaluate multiple oral or parenteral experimental therapies for moderately to severely active Crohn's Disease or Ulcerative Colitis.
