Comparative Study of the Effectiveness of Vedolizumab Versus Ustekinumab After Anti-TNF Failure in Crohn’s Disease (Versus-CD): Data from the ENEIDA Registry

Abstract

Abstract Background Both vedolizumab and ustekinumab are approved for the management of Crohn’s disease [CD]. Data on which one would be the most beneficial option when anti-tumour necrosis factor [anti-TNF] agents fail are limited. Aims To compare the durability, effectiveness, and safety of vedolizumab and ustekinumab after anti-TNF failure or intolerance in CD. Methods CD patients from the ENEIDA registry who received vedolizumab or ustekinumab after anti-TNF failure or intolerance were included. Durability and effectiveness were evaluated in both the short and the long term. Effectiveness was defined according to the Harvey–Bradshaw index [HBI]. The safety profile was compared between the two treatments. The propensity score was calculated by the inverse probability weighting method to balance confounder factors. Results A total of 835 patients from 30 centres were included, 207 treated with vedolizumab and 628 with ustekinumab. Dose intensification was performed in 295 patients. Vedolizumab [vs ustekinumab] was associated with a higher risk of treatment discontinuation (hazard ratio [HR] 2.55, 95% confidence interval [CI]: 2.02–3.21), adjusted by corticosteroids at baseline [HR 1.27; 95% CI: 1.00–1.62], moderate–severe activity in HBI [HR 1.79; 95% CI: 1.20–2.48], and high levels of C-reactive protein at baseline [HR 1.06; 95% CI: 1.02–1.10]. The inverse probability weighting method confirmed these results. Clinical response, remission, and corticosteroid-free clinical remission were higher with ustekinumab than with vedolizumab. Both drugs had a low risk of adverse events with no differences between them. Conclusion In CD patients who have failed anti-TNF agents, ustekinumab seems to be superior to vedolizumab in terms of durability and effectiveness in clinical practice. The safety profile is good and similar for both treatments.
