This is a non-interventional, observational study in participants with IBD participating in the PSP.~This study will enroll approximately 1800 participants. Data collection will be done in 2 components, one is retrospective for participants included in the program before the study starts (from 2016 until study start date) and second is the prospective for participants that were already part of PSP.~Participants will be assigned to following two observational cohorts:~UC participants~CD participants~This single country trial will be conducted in Brazil. The duration of this observational study will be approximately 26 months.
The primary reason of this study is to observe current and past treatment in adult participants receiving Vedolizumab, intravenous (IV) or subcutaneous (SC), for IBD in Brazil. There is no treatment involved in this study, this is only an observational review of past and ongoing treatment data relating to Vedolizumab treatment for IBD (including Ulcerative Colitis [UC] and Crohn's Disease [CD]).
