BACKGROUND: Few data exist to select a second biologic agent in patients with refractory ulcerative colitis (UC). AIM: To compare the efficacy of infliximab (IFX) and vedolizumab (VDZ) in UC patients who failed a first subcutaneous anti-tumor necrosing factor (TNF) agent. METHODS: Consecutive UC patients from 12 French centres starting IFX or VDZ after at least one injection of adalimumab or golimumab have been included in a retrospective study. Outcomes were clinical remission at week 14, survival without treatment discontinuation and survival without UC-related event. RESULTS: Among the 225 patients included, clinical remission at week 14 was achieved in 40/154 (26%) patients treated with IFX and in 35/71 (49%) treated with VDZ (P = 0.001). After a propensity score matching analysis, this difference remained significant (odds ratio: 1.67; 95% confidence interval: 1.08-2.56; P = 0.02). With a median follow-up of 117 weeks, survival rates without treatment discontinuation at years 1 and 3 were 50% and 29% with IFX, and 80% and 55% with VDZ, respectively (P < 0.001). Regarding survival without UC-related event, they were 49% and 27% with IFX, and 74% and 52% with VDZ (P < 0.01). CONCLUSION: After failure of a first subcutaneous anti-TNF agent, UC patients were more likely to achieve clinical remission with VDZ than those treated with IFX. Although due to prescription habits patients in the IFX group had a significantly more severe disease, these differences remained after adjustments and subgroup analyses. Such results have to be confirmed prospectively and warrant dedicated head-to-head trials.
