Patient randomization was stratified by baseline corticosteroid use, endoscopic disease severity, and the number of previously failed biologics. All patients within this dataset were included here within the ITT population. a. Clinical remission per CDAI = per US, CDAI < 150 b. Clinical remission per SF/APS = per EU, average daily SF ≤ 2.8 and average daily APS ≤ 1.0 and both not greater than baseline c. Endoscopic response = decrease in SES-CD > 50% from baseline (or for subjects with a baseline SES-CD of 4, at least a 2-point reduction from baseline), as scored by a central reviewer d. Corticosteroid-free clinical remission = discontinuation of corticosteroid use and achievement of clinical remission per CDAI or SF/APS at wk 12 among patients on corticosteroids at baseline e. Clinical response-100 = decrease of ≥ 100 points in CDAI from baseline f. Endoscopic remission = SES-CD ≤ 4, at least a 2-point reduction versus baseline and no subscore >1 in any individual variable, as scored by a central reviewer g. Results are based on non-responder imputation incorporating multiple imputation to handle missing data due to COVID-19 (NRI-C). h. 95% CI for adjusted difference and p-value are calculated according to the Cochran-Mantel-Haenszel (CMH) test adjusted for randomization strata. **P ≤ .0001 or *P ≤ .01 vs PBO; Average daily abdominal pain score, APS; Coronavirus disease 2019, COVID-19; Confidence Interval, CI; Crohn’s Disease Activity Index, CDAI; Simple Endoscopic Score for CD, SES-CD, Placebo, PBO; Once daily, QD; average daily very soft/liquid stool frequency, SF; Upadacitinib, UPA |
