The goal of this observational study is to learn about how effective Zymfentra (IFX=dyyb) is when treating patients with Crohn's disease (CD) and ulcerative colitis (UC) Does Zymfentra lead to a reduction in symptoms at intervals throughout one year? Participants being prescribed Zymfentra (IFX-dyyb as part of their regular medical care for CD or UC will answer online survey questions about their bowel habits for 1 year.
Evidence of small intestinal inflammation with endoscopically, radiologically or histologically demonstrated ulcerations, fistulation, mucosal fissuring, nodularity or cobblestoning, stricture formation or histologically demonstrated transmural inflammation with or without granuloma formation.
Isolated esophageal, gastric or duodenal inflammation with the finding of noncaseating granuloma.
Colonic inflammation which is patchy (normal segments separating areas of inflammation, as described above) or associated with one or more of the following features: complete rectal sparing, multiple (>10) aphthoid ulcers, deep ulceration (into the muscularis propria), transmural inflammation, extensive fibrosis and wall thickening, fistulation, non-caseating granuloma. (N.B. See note below regarding patchiness of endoscopically observed inflammation in patients with partially treated ulcerative colitis.)
The presence of complex suppurative perianal disease (i.e. more than a superficial fistula or uncomplicated superficial abscess).
