Entyvio (Vedolizumab IV) Extended Access Program in Ulcerative Colitis and Crohn's Disease

The purpose of this study is to monitor ongoing safety in participants with ulcerative colitis (UC) and Crohn's disease (CD) and to provide access to vedolizumab for qualifying participants who, in the opinion of the investigator, continue to derive benefit from vedolizumab and for whom continued treatment with vedolizumab is desired because there is no other comparable product available or the participant may be expected to develop worsening of disease if they were to modify treatment.
