About the study

The primary objective is to evaluate the efficacy and dose response of 3 different dose regimens of TEV-48574 in adult participants with IBD (moderate to severe Ulcerative Colitis (UC) or Crohn's Disease (CD)) as assessed by induction of clinical remission (UC) and endoscopic response (CD) at week 14. Secondary objectives: - To evaluate the efficacy and dose response of the 3 different dose regimens as assessed by multiple standard measures at week 14. - To evaluate the safety and tolerability of the 3 different dose regimens. - To evaluate the immunogenicity of the 3 different dose regimens. The study will consist of a screening period of up to 6 weeks (42 days), a 14-week treatment period, and a 4-week follow-up period.
