645 patients around the world
Available in Spain, Argentina, United States
This platform study will evaluate the efficacy and safety of investigational treatments, including 3 monotherapies and 3 combination therapies, for moderately to severely active UC in adults. The study will progress in two parts. Part A is the open-label portion of the study assessing safety and preliminary efficacy of monotherapies. Part B, which will be open for enrollment after Part A, is the randomized, placebo-controlled portion of the study assessing the safety and efficacy of the 6 interventions (3 monotherapies and 3 combinations) compared to placebo. Intervention arms will be added to the study over time and may complete at different times.
