IntroductionVedolizumab clinical decision support tool (VDZ-CDST) predicts response to vedolizumab, but whether this tool also predicts efficacy of other drugs in Crohn's disease (CD) is unknown. This study aimed to assess the value of VDZ-CDST to predict vedolizumab and ustekinumab efficacy in patients with CD.Patients And MethodsWe included consecutive CD patients refractory or intolerant to anti-TNF who started either vedolizumab or ustekinumab in 5 university hospitals between May 2014 and August 2018. The main end points were the rates of clinical remission and steroid-free clinical remission (SFCR) in each group of VDZ-CDST at week 48.ResultsOne hundred eighty patients were included; 94 received vedolizumab (VDZ-CDST ≤13: 32; VDZ-CDST >13 and ≤19: 52; VDZ-CDST >19: 10), and 86 received ustekinumab (VDZ-CDST ≤13: 16; VDZ-CDST >13 and ≤19: 60; VDZ-CDST >19: 10). At week 48 in the vedolizumab group, clinical remission and SFCR were reached in 9.4% with a VDZ-CDST ≤13, in 38.5% and 28.8% with a VDZ-CDST >13 and ≤19, respectively, and in 80.0% with a VDZ-CDST >19 (P < 0.0001 and P < 0.0001, respectively). In the ustekinumab cohort, clinical remission and SFCR were reached in 43.8% and 37.5% with a VDZ-CDST ≤13, in 55.0% and 50.0% with a VDZ-CDST >13 and ≤19, and 50.0% with a VDZ-CDST >19, respectively (P = 0.65 and P = 0.46, respectively). VDZ-CDST identified SFCR with an area under the curve of 0.69 (95% CI, 0.57-0.82) for vedolizumab and 0.52 (95% CI, 0.40-0.65) for ustekinumab.ConclusionThe VDZ-CDST predicts clinical remission and SFCR at week 48 for vedolizumab but not for ustekinumab in CD patients refractory or intolerant to anti-TNF.© 2021 Crohn’s & Colitis Foundation.
