There is limited real‐world data on comparative effectiveness of different biologic or small molecule agents as second‐line therapies in patients with ulcerative colitis (UC) with prior exposure to a tumour necrosis factor inhibitor (TNFi).

We conducted a retrospective cohort study using TriNetX, a multi‐institutional database to assess the efficacy of tofacitinib, vedolizumab and ustekinumab in patients with ulcerative colitis (UC) with prior exposure to a TNFi. Failure of medical therapy was defined as a composite outcome of intravenous steroids or colectomy within 2 years.
