Abstract
INTRODUCTION We developed and internally validated a prognostic scoring index for ulcerative colitis (UC) patients that includes baseline patient-reported outcomes (PROs), biomarkers, endoscopy, and histology for achieving 1-year endoscopic improvement (EI). METHODS This post hoc analysis included 644 patients treated with ustekinumab induction therapy. Data were randomly split to obtain a 70% training and 30% testing cohort. Multivariate analyses assessed baseline variables and those with P < .05 were assigned weights based on their relative prognostic value from logistic regression modeling for predicting 1-year EI (Mayo endoscopic score ≤1). A cutoff was obtained by calculating the maximum Youden index and validated in the testing cohort. RESULTS Prior biologic failure, albumin <40 g/L, C-reactive protein >5 mg/L, Mayo stool frequency subscore, endoscopic erosions/ulcerations, and chronic histologic structural/architectural changes demonstrated significant associations with 1-year EI and were included in the final model. The Ulcerative Colitis Severity Index (UCSI) had acceptable discriminative ability for 1-year EI in the training (area under the curve [AUC], 0.78; 95% confidence interval, 0.70-0.86) and testing cohort (AUC, 0.76; 95% CI, 0.68-0.85). Compared with the UCSI, the Mayo Clinic score demonstrated poor accuracy (AUC, 0.49; 95% CI, 0.40-0.58) for predicting 1-year EI (P = .0006). The UCSI predicted 1-year endoscopic healing (Mayo endoscopic score = 0), clinical remission (total Mayo Clinic score ≤2 and no subscore >1), partial Mayo score remission <2, and 2-item Patient-Reported Outcome score (Mayo stool frequency and rectal bleeding subscore = 0) with significantly greater accuracy compared with the Mayo Clinic score. DISCUSSION The UCSI is an internally validated prognostic scoring tool that accurately predicts 1-year EI at baseline among moderate-to-severe UC patients initiating therapy. Further validation with additional datasets is needed.

Abstract
BACKGROUND & AIMS We assessed Modified Multiplier Simple Endoscopic Score for Crohn's Disease (MM-SES-CD) and Simple Endoscopic Score for Crohn's Disease (SES-CD) thresholds that are best associated with low likelihood of long-term disease progression. METHODS Data from 61 patients with early Crohn's disease (CD) who participated in the CALM long-term extension study were used as the derivation cohort and validated using the McMaster inflammatory bowel disease database (n = 99). The primary outcome was disease progression (new internal fistula/abscess, stricture, perianal fistula or abscess, CD-related hospitalization or surgery) since the end of the CALM trial. Optimal MM-SES-CD and SES-CD thresholds were determined using the maximum Youden index. Receiver operating characteristic curve analyses compared threshold scores of remission definitions on disease progression. RESULTS In the derivation cohort, based on the maximum Youden index, the optimal thresholds associated with a low likelihood of disease progression were MM-SES-CD <22.5 and SES-CD <4. A significantly greater proportion of patients with a MM-SES-CD ≥22.5 had disease progression as compared with patients in the derivation cohort with MM-SES-CD <22.5 (10/17 [58.8%] vs 3/44 [6.8%]; P < .001). Similarly, a significantly greater number of patients with SES-CD ≥ 4 had disease progression compared with those with a SES-CD <4 (11/25 [44.0%] vs 2/36 [5.6%]; P < .001). Compared with other clinical or endoscopic remission definitions, which demonstrated poor to fair accuracy, MM-SES-CD <22.5 performed the best for predicting disease progression (area under the curve = 0.81; 95% confidence interval, 0.68-0.94; P < .001). These thresholds were confirmed in the validation cohort. CONCLUSION Achievement of MM-SES-CD <22.5 or SES-CD <4 in patients with ileocolonic or colonic CD is associated with low risk of disease progression and may be suitable targets in clinical trials and practice for endoscopic healing.

Abstract
INTRODUCTION Differences in 1-year outcomes among early and delayed responders have been demonstrated with some therapies in ulcerative colitis. However, it is unclear whether similar differences exist in patients with Crohn's disease (CD) treated with biologic therapies. METHODS This was a post hoc analysis of patient-level data from the SEAVUE clinical trial program. Ustekinumab-treated and adalimumab-treated patients with clinical response at week 8, defined as a reduction in Crohn's Disease Activity Index (CDAI) score of at least 100 points from baseline or CDAI score <150, were deemed early responders and their outcomes were compared with delayed responders (week 8 nonresponders who subsequently responded at week 16) and nonresponders (no response at week 8 or 16). The primary outcome assessed was clinical remission at week 56, defined as CDAI <150. RESULTS A total of 373 participants (187 treated with ustekinumab and 186 treated with adalimumab) were included in this analysis. The overall rate of delayed clinical response was low in the SEAVUE clinical trial program (13.1%). No differences were observed for week 56 clinical remission among early vs delayed responders to ustekinumab or adalimumab nor were there significant differences for secondary outcomes assessed. Delayed responders to ustekinumab and adalimumab had a significant decline in C-reactive protein by week 8 when compared with nonresponders. DISCUSSION Among patients with moderate-to-severe CD, early and delayed responders to adalimumab and ustekinumab have similar 1-year clinical outcomes. Biomarker decline can be observed through the initial 8 weeks of therapy in patients who will eventually be delayed responders, which may help differentiate from nonresponders.

Abstract
BACKGROUND & AIMS Differences in 1-year outcomes among early compared with delayed responders to vedolizumab have been shown in ulcerative colitis. However, it is unclear whether similar differences exist with ustekinumab, and what factors differentiate delayed responders from nonresponders. METHODS This study was a post hoc analysis of patient-level data from the UNIFI clinical trial. Ustekinumab-treated patients with clinical response, defined as a reduction in total Mayo score of 30% or more and 3 or more points from baseline with a reduction in their rectal bleeding subscore of 1 or more or a rectal bleeding subscore of 1 or less, at week 8 were deemed early responders and their outcomes were compared with delayed responders (week 8 nonresponders who subsequently responded at week 16). The primary outcome assessed was 1-year clinical remission, defined as a total Mayo score of 2 or less and no subscore greater than 1. RESULTS We included 642 ustekinumab-treated patients, including 321 (50%) early responders, 115 (17.9%) delayed responders, and 205 (32.1%) nonresponders. No differences were observed for 1-year clinical remission among early vs delayed responders (132 of 321 [41.1%] vs 40 of 115 [34.8%]; P = .233), or for other outcomes assessed regardless of induction dose. Compared with early responders, delayed responders had more severe baseline Mayo endoscopic disease (88 of 115 [76.5%] vs 206 of 321 [64.2%]; P = .015) and abnormal baseline C-reactive protein level greater than 3 mg/L (83 of 115 [72.2%] vs 183 of 321 [57%]; P = .004). Compared with nonresponders, delayed responders had a significant decrease in C-reactive protein level (F-value [degrees of freedom, mean squares] [4, 844]; P < .0001) and fecal calprotectin level (F[4, 818]; P < .0001) through week 16. CONCLUSIONS Compared with early ustekinumab responders, delayed responders had a greater inflammatory burden at baseline. Early and delayed responders had similar 1-year outcomes. Biomarker decline observed in delayed responders can help differentiate them from nonresponders.

Abstract
INTRODUCTION There is an urgent need to understand the long-term real-world effectiveness of ustekinumab (UST) in the treatment of Crohn's disease (CD), fistulizing CD (FCD), and ulcerative colitis (UC). Persistence on treatment is commonly used as a surrogate measure of real-world treatment response. This study aims to estimate the long-term real-world persistence of UST in adult patients with CD, FCD, and UC. METHODS A retrospective study was conducted in patients with CD, FCD, and UC treated with UST through a national patient support program in Canada. Treatment persistence was described using the Kaplan-Meier method, and the impact of patient characteristics on persistence was explored through stratified analyses and multivariable Cox proportional hazards models. RESULTS Persistence rates for 8724 patients with CD were 82.9%, 71.4%, 64.1%, and 59.7% at 1, 2, 3, and 4 years, respectively. Similarly, persistence rates for 276 patients with FCD were 84.1%, 70.9%, 64.9%, and 63.1% at 1, 2, 3, and 4 years, respectively. Persistence rates for 1291 patients with UC were 76.5% at 1 year and 69.5% at 1.5 years. When stratified by prior IBD-indicated biologic experience, persistence was numerically higher in biologic-naïve patients across all disease cohorts. A Cox proportional hazards model confirmed that this difference was significant in patients with CD (hazard ratio: 0.72; confidence interval: [0.65-0.79]). CONCLUSIONS This study estimated long-term persistence in a large population of patients with IBD. At 1 year, over three-fourths of patients remained on UST treatment in all disease cohorts, and over half of patients remained on treatment at 4 years in CD and FCD patients. Biologic-naïve status was significantly associated with higher persistence in patients with CD.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic, allergic disease of the esophagus. Current treatment options are limited. One experimental therapy is antibodies against interleukin-5 (IL-5). However, it is unknown why some patients respond to anti-IL-5 treatment whereas others do not. We sought to delineate predictors of histologic response to anti-IL-5 therapy in pediatric EoE. METHODS This post hoc analysis of a multicenter, double-blind clinical trial (ClinicalTrial.gov identifier: NCT00358449) evaluated mepolizumab for the treatment of EoE in pediatric patients. Predictors were assessed for their association with a histologic response at week 12 of treatment. A histologic response was defined as either <15 eosinophils per hpf or a reduction in peak eosinophil counts by ≥50%. Predictors on univariate analysis with P < 0.10 were included in multivariate logistic regression models. Statistical significance for multivariate comparisons was set at P < 0.05. RESULTS Patients with a higher BMI were more likely to attain histologic response at week 12, defined as <15 eosinophils per hpf [aOR, 1.31; 95% confidence interval (CI), 1.07-1.60; P = 0.008]. Higher BMI (aOR, 1.70; 95% CI, 1.06-2.74; P = 0.029) and signs of exudate plaques on endoscopy (aOR, 18.30; 95% CI, 2.11-158.53; P = 0.008) were significant predictors of histologic response at week 12 where a histologic response was defined as a reduction in peak eosinophil counts by ≥50. CONCLUSION Higher BMI and signs of exudative plaques on endoscopy may be predictors of histologic response in pediatric EoE patients treated with antibodies against IL-5. Further studies are needed to validate our findings.

Abstract
BACKGROUND This analysis evaluates the association between baseline patient-reported symptom (PRS) severity in Crohn's disease (CD), including abdominal pain, stool frequency, general well-being, and achievement of clinical and endoscopic outcomes. We compared baseline PRS to baseline endoscopic scores for the prediction of endoscopic remission (ER). METHODS This post hoc analysis of 2 clinical trials of infliximab in CD included 601 patients and evaluated baseline PRS variables (abdominal pain, stool frequency, and general well-being) as measured by the Crohn's disease activity index and their association with 6-month clinical remission (CR) (Crohn's Disease Activity Index<150), corticosteroid-free CR, and week 26/54 ER (absence of mucosal ulceration). Logistic regression models assessed the relationships between PRS and outcomes of interest. Receiver operating characteristic curve analyses compared the sensitivity and specificity of the different baseline PRS compared with baseline endoscopic scores for achievement of ER at weeks 26 and 54. RESULTS No difference was found comparing patients with higher baseline PRS to those with lower PRS in achieving 6-month CR, 6-month corticosteroid-free CR, or week 26/54 ER. Modified multiplier of the SES-CD (MM-SES-CD) at baseline demonstrated a significant ability to predict week 54 ER (area under the curve, 0.71; 95% CI 0.65-0.78; P =0.017). CONCLUSIONS Baseline PRS in CD is not prognostic of clinical or endoscopic response. In contrast, active endoscopic disease as measured by the MM-SES-CD, more accurately predicts endoscopic outcomes. Endoscopic scores such as the MM-SES-CD may be considered for selection criteria and as a primary outcome of interest in CD trials, with PRS as a co-primary or secondary endpoint.

Abstract
BACKGROUND & AIMS The cause of Crohn's disease (CD) is unknown, but the current hypothesis is that microbial or environmental factors induce gut inflammation in genetically susceptible individuals, leading to chronic intestinal inflammation. Case-control studies of patients with CD have cataloged alterations in the gut microbiome composition; however, these studies fail to distinguish whether the altered gut microbiome composition is associated with initiation of CD or is the result of inflammation or drug treatment. METHODS In this prospective cohort study, 3483 healthy first-degree relatives (FDRs) of patients with CD were recruited to identify the gut microbiome composition that precedes the onset of CD and to what extent this composition predicts the risk of developing CD. We applied a machine learning approach to the analysis of the gut microbiome composition (based on 16S ribosomal RNA sequencing) to define a microbial signature that associates with future development of CD. The performance of the model was assessed in an independent validation cohort. RESULTS In the validation cohort, the microbiome risk score (MRS) model yielded a hazard ratio of 2.24 (95% confidence interval, 1.03-4.84; P = .04), using the median of the MRS from the discovery cohort as the threshold. The MRS demonstrated a temporal validity by capturing individuals that developed CD up to 5 years before disease onset (area under the curve > 0.65). The 5 most important taxa contributing to the MRS included Ruminococcus torques, Blautia, Colidextribacter, an uncultured genus-level group from Oscillospiraceae, and Roseburia. CONCLUSION This study is the first to demonstrate that gut microbiome composition is associated with future onset of CD and suggests that gut microbiome is a contributor in the pathogenesis of CD.

Abstract
BACKGROUND In placebo-controlled clinical trials for Crohn's disease (CD), some placebo-treated patients demonstrate improvement. However, it is unclear what factors contribute to placebo response and remission. METHODS This was a post hoc analysis of 3 placebo-controlled clinical trial programs (GEMINI-2, UNITI-1/2, and CLASSIC-1) of moderate-severe CD evaluating the efficacy of vedolizumab, ustekinumab, and adalimumab. Baseline predictors of clinical remission at the end of induction (week 4/6), defined as Crohn's Disease Activity Index <150 were evaluated among placebo-treated patients. Clinical response (decrease in Crohn's Disease Activity Index ≥100 points from baseline) at the end of induction was also evaluated. Univariate analyses were performed and predictors with P < .10 were included in multivariable analyses. RESULTS A total of 683 patients (148 from GEMINI-2, 470 from UNITI-1/2, and 65 from CLASSIC-1) treated with placebo were included. Of the predictors evaluated, C-reactive protein <5 mg/L (odds ratio [OR], 1.66; 95% confidence interval [CI], 1.04-2.67; P = .035), albumin >40 g/L (OR, 1.57; 95% CI, 1.05-2.93; P = .023), and disease duration <5 years (OR, 1.70; 95% CI, 1.05-2.75; P = .032) were included in the multivariable model for clinical remission. Disease duration <5 years was the only variable that retained significance on multivariable analysis (adjusted OR, 1.67; 95% CI, 1.02-2.73; P = .040). For clinical response, isolated ileal disease and disease duration <1 year were included in the multivariable model, of which only the latter retained significance (adjusted OR, 1.84; 95% CI, 1.04-3.24; P = .035). CONCLUSIONS Strategies that reduce placebo response rates in clinical trials of CD should be considered, including stratification or exclusion of subjects by disease duration and mild disease severity as measured by objective biomarkers.

Abstract
BACKGROUND & AIMS Several medications have been suspected to contribute to the etiology of inflammatory bowel disease (IBD). This study assessed the association between medication use and the risk of developing IBD using the Prospective Urban Rural Epidemiology cohort. METHODS This was a prospective cohort study of 133,137 individuals between the ages of 20 and 80 from 24 countries. Country-specific validated questionnaires documented baseline and follow-up medication use. Participants were followed up prospectively at least every 3 years. The main outcome was the development of IBD, including Crohn's disease (CD) and ulcerative colitis (UC). Short-term (baseline but not follow-up use) and long-term use (baseline and subsequent follow-up use) were evaluated. Results are presented as adjusted odds ratios (aORs) with 95% CIs. RESULTS During a median follow-up period of 11.0 years (interquartile range, 9.2-12.2 y), there were 571 incident IBD cases (143 CD and 428 UC). Incident IBD was associated significantly with baseline antibiotic (aOR, 2.81; 95% CI, 1.67-4.73; P = .0001) and hormonal medication use (aOR, 4.43; 95% CI, 1.78-11.01; P = .001). Among females, previous or current oral contraceptive use also was associated with IBD development (aOR, 2.17; 95% CI, 1.70-2.77; P < .001). Nonsteroidal anti-inflammatory drug users also were observed to have increased odds of IBD (aOR, 1.80; 95% CI, 1.23-2.64; P = .002), which was driven by long-term use (aOR, 5.58; 95% CI, 2.26-13.80; P < .001). All significant results were consistent in direction for CD and UC with low heterogeneity. CONCLUSIONS Antibiotics, hormonal medications, oral contraceptives, and long-term nonsteroidal anti-inflammatory drug use were associated with increased odds of incident IBD after adjustment for covariates.

Abstract
OBJECTIVE In the absence of head-to-head clinical trials, indirect comparative studies are needed to help position therapies in ulcerative colitis (UC). We aimed to compare the efficacy of infliximab vs. tofacitinib for moderate-severe UC among biologic-naïve participants at post-induction. METHODS This was a post-hoc analysis of patient-level data from four clinical trials including 659 biologic-naïve UC participants. We compared proportions of patients achieving week 8 clinical remission (CR), endoscopic improvement, and endoscopic remission. Clinical response at week 2 was also assessed. Multiple logistic regression models were adjusted for potential confounders identified as having an association with the outcome of interest on univariate analysis. Propensity scores were calculated to create a cohort of participants with similar distribution of baseline co-variates. RESULTS Patients treated with infliximab had significantly greater odds of CR at week 8 compared to tofacitinib [88/242 (36.4%) vs. 100/417 (24.0%), aOR: 1.65 (95% CI 1.11-2.44), p = 0.013]. Endoscopic improvement at week 8 was also significantly greater among infliximab-treated patients [149/242 (61.6%) vs. 159/417 (38.1%), aOR: 2.12 (95% CI 1.45-3.10), p < 0.001]. Similar findings were observed with week 8 endoscopic remission [61/242 (25.2%) vs. 43/417 (10.3%); aOR: 2.72 (95% CI 1.66-4.46), p < 0.001]. A similar proportion of participants attained clinical response at week 2 [205/242 (84.7%) vs. 334/417 (80.1%), aOR: 1.48 (95% CI 0.93-2.37), p = 0.101]. Similar results were observed among the propensity score matched cohort. CONCLUSION Based on the efficacy observed in this post-hoc analysis, consideration should be given to use of infliximab over tofacitinib for treatment of moderate to severe biologic-naïve UC. However, baseline characteristic mismatches persisted despite propensity score matching, and further studies are needed to confirm our findings.

Abstract
BACKGROUND & AIMS High placebo response rates in clinical trials of ulcerative colitis (UC) have been reported previously. However, data from patient-level analyses are lacking. We assessed factors associated with clinical and endoscopic placebo response among placebo-treated patients in clinical trials of UC. METHODS We performed a post hoc analysis of pooled clinical trial data from GEMINI-1, ACT-1, ACT-2, PURSUIT, ULTRA-2, OCTAVE-1, and OCTAVE-2. Predictors were assessed in placebo-treated patients for their association with end of induction (week 6 of 8) clinical response (reduction in total Mayo score of ≥3 and ≥30% from baseline with ≥1 point decrease in rectal bleeding subscore [RBS] or absolute RBS ≤1); clinical remission (total Mayo score ≤2 and no subscore >1); endoscopic healing (Mayo endoscopic subscore ≤1); partial Mayo score of 0; patient-reported outcome 2-item remission (RBS of 0 and stool frequency ≤1), resolution of rectal bleeding, and stool frequency normalization. Predictors on univariate analyses with P < .05 were included in multivariate logistic regression models. RESULTS Placebo-treated patients with normal serum C-reactive protein and albumin levels were more likely to attain clinical response (71 of 437 [16.3%] vs 49 of 660 [7.4%]; adjusted odds ratio, 2.76; 95% confidence interval, 1.19-5.41; P = .018). Compared with patients with a Mayo endoscopic score of 2, patients with a Mayo endoscopic score of 3 were less likely to attain clinical response (105 of 556 [18.8%] vs 179 of 675 [25.9%]; adjusted odds ratio, 0.33; 95% confidence interval, 0.16-0.68; P = .003). Similar findings were observed for clinical remission and resolution of rectal bleeding. CONCLUSIONS Biomarkers such as normal serum C-reactive protein and albumin and baseline endoscopic severity were found to affect placebo response rates in clinical trials of UC. These findings have implications for clinical trial design in UC.

Abstract
Background The pathogenesis of inflammatory bowel disease (IBD) which includes Crohn’s disease (CD) and ulcerative colitis (UC), is believed to involve activation of the intestinal immune system in response to the gut microbiome among genetically susceptible hosts. IBD has been historically regarded as a disease of developed nations, though in the past two decades there has been a reported shift in the epidemiological pattern of disease. High-income nations with known high prevalence of disease are seeing a stabilization of incident cases, while a rapid rise of incident IBD is being observed in developing nations. This suggests that environmental exposures may play a role in mediating the risk of developing IBD. The potential environmental determinants of IBD across various regions is vast, though medications have been increasingly recognized as one broad category of risk factors. Purpose Several medications have been considered to contribute to the etiology of IBD. This study assessed the association between medication use and risk of developing IBD using the Prospective Urban Rural Epidemiology (PURE) cohort. Method This was a prospective cohort study of 133,137 individuals between the ages of 20-80 from 24 countries. Country-specific validated questionnaires documented baseline and follow-up medication use. Participants were followed prospectively at least every 3 years. The main outcome was development of IBD, including CD and UC. Short-term (baseline but not follow-up use) and long-term use (baseline and subsequent follow-up use) was evaluated. Results are presented as adjusted odds ratios (aOR) with 95% confidence intervals (CI). Result(s) During the median follow-up of 11.0 years [interquartile range (IQR) 9.2-12.2], we recorded 571 incident cases of IBD (143 CD and 428 UC). Higher risk of incident IBD was associated with baseline antibiotic use [aOR: 2.81 (95% CI: 1.67-4.73), p=0.0001] and hormonal medication use [aOR: 4.43 (95% CI: 1.78-11.01), p=0.001]. Among females, previous or current oral contraceptive use was also associated with IBD development [aOR: 2.17 (95% CI: 1.70-2.77), p=5.02E-10]. NSAID users were also observed to have increased risk of IBD [aOR: 1.80 (95% CI: 1.23-2.64), p=0.002], which was driven by long-term users [aOR: 5.58 (95% CI: 2.26-13.80), p<0.001]. All significant results were consistent in direction for CD and UC with low heterogeneity. Conclusion(s) Antibiotics, hormonal medications, oral contraceptives, and long-term NSAID use were associated with increased odds of incident IBD after adjustment for covariates.

Abstract
Background The incidence of Crohn’s disease (CD) is increasing globally, indicating a significant environmental influence such as diet. A plethora of dietary adherence (DA) patterns exist in the literature: the Mediterranean Diet (MD), Empirical Dietary Inflammatory Pattern (EDIP), Specific Carbohydrate Diet (SCD), and low Fermentable Oligosaccharide, Disaccharide, Monosaccharide, or Polyol diet (FODMAP) are all potential candidates to maintain a reduced level of inflammation, improving gastrointestinal function. Contrary, the Westernized diet (WD) is generally reported as a diet promoting inflammation in humans. Purpose To determine if DA to literature-derived dietary indices in a cohort of first-degree relatives (FDRs) of CD patients can modulate pre-disease biomarkers. Method We used food frequency questionnaire (FFQ) data from 2,696 healthy FDR subjects of the Crohn’s Colitis Canada- Genes, Environment, Microbial (CCC-GEM) project. We rederived each of the following scores using our FFQ data, utilizing originally described methods for the MD, EDIP, SCD, low FODMAP, and WD to obtain DA. Each diet was correlated pairwise via Kendall’s Tau. We fit multivariable regression models to identify the association of DA (top quintile vs remaining) and: i) intestinal permeability using urinary fractional excretion of lactulose to mannitol ratio (LMR), LMR≥0.03 defined abnormal; ii) subclinical inflammation using fecal calprotectin (FCP) measured with BÜHLMANN fCAL® ELISA, FCP≥250µg/g defined inflammation; and iii) fecal microbiome richness and composition using 16S rRNA sequencing. Two-sided p<0.05 for primary and q<0.05 for secondary analysis defined significance. Result(s) There were positive correlations between the MD, SCD, and low FODMAP, these diets negatively correlated with the WD. The EDIP negatively correlated with the SCD and low FODMAP, did not correlate with the MD, and positively correlated with the WD. No diet was associated with abnormal LMR or FCP. Only the SCD was associated with increased microbial richness (q=0.03). All diets were associated with microbial genera: the MD (n=18 taxa, (2.0-7<q-values< 0.04), EDIP (n=9, [2.8-4-0.05]), SCD (n=13, [3.7-11-0.05]), low FODMAP (n=14, [1.3-7-0.05]), and WD (n=1, [0.03]). Conclusion(s) This study shows that literature-derived dietary indices correlate generally with each other, yet none were not associated with abnormal LMR or FCP. However, we found that diet can impact microbiome richness and composition. Thus, it is tempting to speculate that diet is a possible intervention capable of maintain microbiome homeostasis to reduce future risk of CD. Submitted on behalf of the CCC-GEM consortium.

Abstract
Background Crohn’s disease (CD) is a chronic relapsing inflammatory disease of the gastrointestinal tract. The etiology of CD may arise from complex interactions including host genetics, diet, and the intestinal microbiome. Increased consumption of saturated fats, characteristic of the Western diet, is a known risk factor for CD. Dietary fat (DF) is absorbed by the host through the release of primary bile acids (PBAs) and bio-transformed by the microbiome into secondary bile acids (SBAs). Altogether, bile acids (BAs) can act as signaling molecules involved in host immune regulation and potentially in CD onset. Purpose To investigate the relationship between CD risk, BAs, and DF, and evaluate the predictive performance of CD onset of these factors by developing machine learning models. Method We used samples healthy first-degree relatives (FDRs) recruited as part of the Crohn’s Colitis Canada- Genes, Environment, Microbial (GEM) project. Those who developed CD (n=87) were matched 1:4 by age, sex, follow-up time, and geographic location with control FDRs remaining healthy (n=347). Serum, urine, and stool BA were measured using ultrahigh Performance Liquid Chromatography-Tandem Mass Spectroscopy. DF types were derived from food frequency questionnaire data. We used conditional logistic regressions to identify associations between CD onset, BAs (n=93), and DFs (n=9). We further explored the relationships of significant CD-related BAs and DF via Generalized Estimation Equations. Finally, we used a tree-based machine-learning algorithm (XGBoost) with 5-fold cross-validation to assess the prediction performance of CD onset using BA from all sources as well as DF. Two-sided p<0.05 was considered significant. Result(s) In total, 10 of 93 BAs, and two of nine DFs were significantly associated with increased odds of CD onset (p<0.05). Additionally, five BAs were significantly associated with DF (p<0.05). Serum-derived BAs had the best predictive performance for CD, with a mean AUC of 0.70 [95% CI: 0.63;0.76], followed by stool derived BAs with a mean AUC= 0.65 [0.55;0.75], and followed by urine derived Bas with a mean AUC= 0.57 [0.48;0.66]. Lastly DF was not a predictive marker of CD onset with a mean AUC= 0.50 [0.41;0.60]. Conclusion(s) This study suggests that BAs are associated with the pathogenesis of CD and the effects may be influenced by DF. Serum-derived BAs may be able to better predict the risk of CD than other stool or urine derived BA, while DF is not directly implicated in CD risk. Submitted on behalf of the CCC-GEM consortium.

Abstract
BACKGROUND AND AIMS Evaluating histologic outcomes in ulcerative colitis (UC) has become common in recent clinical trials. In this study, we explored the additional value of the combined endpoint of histo-endoscopic mucosal improvement (HEMI) compared to endoscopic improvement (EI) at post-induction (week 14) and post-maintenance (one-year). METHODS This post-hoc analysis included 620 UC participants with available data from the VARSITY trial. Participants achieving post-induction and post-maintenance HEMI (Mayo endoscopic subscore ≤ 1 and Geboes score < 3.2) were compared across clinical outcomes, PROs, and inflammatory markers. Univariate analyses were performed to identify variables associated with the outcome of interest. Multivariate analyses included co-variates with a p<0.05 on univariate analyses. RESULTS Among the 468 patients with one-year data available, a total of 166 (35.5%) attained HEMI and 209 (44.7%) attained EI at post-induction. No difference in achievement of CR at one-year was observed among those who attained post-induction HEMI vs. EI [121/166 (72.9%) vs. 147/209 (70.3%), p=0.903]. Similar findings were observed for the outcome of one-year treatment failure [45/166 (27.1%) vs. 55/209 (26.3%), p=0.781]. Patients who achieved HEMI at post-induction had lower total and partial Mayo scores and had the largest improvement from baseline. Fecal calprotectin and CRP were also significantly lower among HEMI achievers at post-induction (p<0.001). Similar findings were observed at post-maintenance. CONCLUSIONS In this post-hoc analysis, at post-induction, HEMI did not demonstrate additional prognostic value in predicting one-year outcomes over EI. However, HEMI was associated with lower clinical disease activity at post-induction and at one-year compared to endoscopic or histologic outcomes in isolation.

Abstract
BACKGROUND Indirect treatment comparisons using patient-level data are increasing in popularity within inflammatory bowel disease research. We compared the efficacy of adalimumab and vedolizumab for biologic-naïve moderate-severe ulcerative colitis (UC) using indirect comparisons of phase 3 clinical trials and compared the results to the RCT VARSITY. DESIGN Pooled analysis of patient-level data from 518 biologic-naïve patients with UC was performed using GEMINI-1 and ULTRA-1. Proportions of patients achieving week 6 clinical remission and clinical response were compared, and propensity score matching and multivariate logistic regression were used to account for potential confounders. These results were compared to those derived from VARSITY. RESULTS A numerically greater proportion of vedolizumab-treated patients from GEMINI-1 achieved week 6 clinical remission compared to those treated with adalimumab [136/388 (35.1%) vs. 38/130 (29.2%)]. Similar findings were observed among the propensity score matched cohort [33/110 (30.0%) vs. 25/110 (22.7%), adjusted OR (aOR) 1.56 (95% confidence interval (CI) 0.81-3.02), p = 0.187]. A similar magnitude for absolute difference in the proportions of patients achieving week 6 clinical remission was observed from VARSITY in vedolizumab compared to adalimumab [131/305 (43.0%) vs. 114/307 (37.1%), OR 1.27 (95% CI 0.92-1.76), p = 0.142]. CONCLUSIONS In this post hoc analysis, a similar magnitude in the absolute difference of efficacy at week 6 among biologic-naïve patients was observed using indirect comparisons of phase 3 clinical trial data as was observed in VARSITY. Indirect comparisons using patient-level clinical trial data could be used to inform drug choices for future head-to-head trials and guide positioning of drugs in the absence of head-to-head trials.

Abstract
BACKGROUND Patient-reported outcomes (PROs) are increasingly emphasized as endpoints in clinical trials of ulcerative colitis (UC). However, the prognostic value of early improvement in PROs for long-term outcomes remains unclear. METHODS This was a post-hoc analysis of 611 vedolizumab-treated or adalimumab-treated patients in the VARSITY trial (Clinicaltrial.gov: NCT02497469). Stool frequency (SF) and rectal bleeding score (RBS) as reported in the Mayo score at post-induction (week 6 and 14) was assessed for their association with one-year endoscopic improvement (EI), defined as Mayo endoscopic subscore <2; histo-endoscopic mucosal improvement (HEMI), defined as EI and Geboes highest grade <3.2, clinical remission (CR), defined as total Mayo score ≤2; and PRO-2 remission, defined as RBS of 0 and SF ≤1. Multivariable logistic regression models adjusted for confounders assessed the relationships between post-induction PROs and outcomes of interest at one-year. RESULTS Patients with severe SF at week 6 were significantly less likely to achieve one-year EI compared to those with non-severe SF [aOR 0.40 (95% CI: 0.24-0.68), p < .001]. Absence of rectal bleeding at week 6 was associated with greater odds of achieving EI at one-year [aOR 2.21 (95% CI: 1.58-3.09), p < .001]. These findings were consistent across comparisons at week 14. Similar findings were observed for the outcomes of one-year HEMI, CR and PRO-2 remission. No difference was observed between the modified partial Mayo score and modified PRO-2 score. CONCLUSIONS Post-induction PROs strongly predict the odds of CR and EI in UC and simplified evaluations can be used to assess early response to UC therapies.

Abstract
BACKGROUND There remains limited data supporting the efficacy of dietary therapy in adults with Crohn's disease (CD). This was a pilot study of the McMaster Elimination diet for CD (MED-CD), which excludes several potentially detrimental ingredients commonly found in the Western diet. METHODS Prospective study in adults with mild-moderately active CD [Harvey-Bradshaw Index (HBI) scores 5-16] and endoscopic disease activity of >7 (or ≥4 for isolated ileal disease) as measured by the Simple Endoscopic Score for Crohn's disease (SES-CD). Patients were treated for 2 weeks using oral enteral nutrition (EN). Those with symptomatic improvement (HBI score reduction ≥2) were transitioned to the MED-CD for 12 weeks. Outcomes of interest included satisfactory adherence (≥20 on the modified medical adherence report scale-5 questionnaire), clinical remission (CR) (HBI ≤4), clinical response (HBI reduction ≥3), endoscopic response (SES-CD reduction ≥50%), and endoscopic remission (ER) (SES-CD <3). RESULTS A total of 17 patients were treated with 2 weeks of EN. Of these, 13 were deemed responders and treated with 12 weeks of MED-CD. Satisfactory adherence was reported among 11/13 (84.6%) at week 6 and 8/12 (67%) at week 14. Of the 13 patients who responded to EN by week 2, 5 (38.5%) had attained CR at week 2 and maintained CR until week 14 using MED-CD. Endoscopic response was observed in 6 (46.2%) participants and ER was seen in 2 (15.4%). CONCLUSIONS Two weeks of oral EN followed by 12 weeks of the MED-CD was acceptable by most adult patients who enroled in this study.

Abstract
BACKGROUND & AIMS The gut microbiome has been suggested to play a role in gut barrier hemostasis, but data are scarce and limited to animal studies. We therefore aimed to assess whether alterations in gut microbial composition and functional pathways are associated with gut barrier function in a cohort of healthy first-degree relatives of patients with Crohn's disease. METHODS We used the Crohn's and Colitis Canada Genetic Environmental Microbial (CCC-GEM) cohort of healthy first-degree relatives of patients with Crohn's disease. Gut barrier function was assessed using the urinary fractional excretion of lactulose-to-mannitol ratio (LMR). Microbiome composition was assessed by sequencing fecal 16S ribosomal RNA. The cohort was divided into a discovery cohort (n = 2472) and a validation cohort (n = 655). A regression model was used to assess microbial associations with the LMR. A random forest classifier algorithm was performed to assess microbial community contribution to barrier function. RESULTS Individuals with impaired barrier function (LMR >0.025) had reduced alpha-diversity (Chao1 index, P = 4.0e-4) and altered beta-diversity (Bray-Curtis dissimilarity index, R2 = 0.001, P = 1.0e-3) compared with individuals with an LMR ≤0.025. When taxa were assessed individually, we identified 8 genera and 52 microbial pathways associated with an LMR >0.025 (q < 0.05). Four genera (decreased prevalence of Adlercreutzia, Clostridia UCG 014, and Clostridium sensu stricto 1 and increased abundance of Colidextribacter) and 8 pathways (including decreased biosynthesis of glutamate, tryptophan, and threonine) were replicated in the validation cohort. The random forest approach revealed that the bacterial community is associated with gut barrier function (area under the curve, 0.63; P = 1.4e-6). CONCLUSIONS The gut microbiome community and pathways are associated with changes in gut barrier function. These findings may identify potential microbial targets to modulate gut barrier.

Abstract
BACKGROUND We evaluated whether postinduction ulcer size and patient-reported outcome (PRO) severity are associated with the achievement of 1-year endoscopic remission (ER) in patients with Crohn's disease (CD). METHODS This post hoc analysis combined data from several clinical trials including 283 patients with baseline ulcers ≥5 mm with repeat endoscopy after ustekinumab or adalimumab induction therapy. Patient-reported outcomes including stool frequency (SF) and abdominal pain (AP) were measured by the Crohn's Disease Activity Index. Thresholds of SF ≥4 and/or AP ≥2 indicated moderately to severely active CD. Endoscopic remission was defined as Simple Endoscopic Score for CD (SES-CD) <3. Multivariate logistic regression models adjusted for confounders (including disease duration and treatment allocation) evaluated the relationships between postinduction ulcer size, PRO symptoms, and achievement of 1-year ER. RESULTS Among the 131 CD patients who continued to have ulcers ≥5 mm after induction therapy, 48 (36.6%) achieved 1-year ER. Patients with postinduction ulcers ≥5 mm were approximately 5 times less likely to achieve 1-year ER than the 152 individuals who had small or no postinduction ulcers (odds ratio [OR], 0.20; 95% CI, 0.08-0.51, P = .001). In patients with ulcers ≥5 mm after induction, postinduction PRO scores (including PRO2 and PRO3) did not predict 1-year ER. CONCLUSIONS Crohn's disease patients with ulcers ≥5 mm after induction therapy are less likely to achieve 1-year ER. Postinduction PRO severity does not offer additional prognostic information. This may suggest that objective measures of disease such as endoscopic ulcer size should be considered over symptom assessments for determining clinical response to therapy and utilized in trials for maintenance therapy.

Abstract
BACKGROUND & AIMS Case-control studies have shown that patients with Crohn's disease (CD) have a microbial composition different from healthy individuals. Although the causes of CD are unknown, epidemiologic studies suggest that diet is an important contributor to CD risk, potentially via modulation of bacterial composition and gut inflammation. We hypothesized that long-term dietary clusters (DCs) are associated with gut microbiome compositions and gut inflammation. Our objectives were to identify dietary patterns and assess whether they are associated with alterations in specific gut microbial compositions and subclinical levels of gut inflammation in a cohort of healthy first-degree relatives (FDRs) of patients with CD. METHODS As part of the Genetic, Environmental, Microbial (GEM) Project, we recruited a cohort of 2289 healthy FDRs of patients with CD. Individuals provided stool samples and answered a validated food frequency questionnaire reflecting their habitual diet during the year before sample collection. Unsupervised analysis identified 3 dietary and 3 microbial composition clusters. RESULTS DC3, resembling the Mediterranean diet, was strongly associated with a defined microbial composition, with an increased abundance of fiber-degrading bacteria, such as Ruminococcus, as well as taxa such as Faecalibacterium. The DC3 diet was also significantly associated with lower levels of subclinical gut inflammation, defined by fecal calprotectin, compared with other dietary patterns. No significant associations were found between individual food items and fecal calprotectin, suggesting that long-term dietary patterns rather than individual food items contribute to subclinical gut inflammation. Additionally, mediation analysis demonstrated that DC3 had a direct effect on subclinical inflammation that was partially mediated by the microbiota. CONCLUSIONS Overall, these results indicated that Mediterranean-like dietary patterns are associated with microbiome and lower intestinal inflammation. This study will help guide future dietary strategies that affect microbial composition and host gut inflammation to prevent diseases.

Abstract
BACKGROUND AND AIMS Current endoscopic scoring indices such as the Simple Endoscopic Score for Crohn's Disease [SES-CD] quantify the degree of mucosal inflammation in Crohn's disease [CD] but lack prognostic potential. The Modified Multiplier of the SES-CD [MM-SES-CD] quantifies the endoscopic burden of CD and can be accessed online [https://www.mcmasteribd.com/mm-ses-cd]. This analysis aims to establish MM-SES-CD thresholds that classify CD endoscopic burden into inactive/very mild, mild, moderate, and severe disease based on the probability of achieving endoscopic remission [ER] on active therapy at 1 year. METHODS This post-hoc analysis included pooled data from three CD clinical trials [n = 350 patients, baseline SES-CD ≥3 with ulceration]. Disease category severity was determined using the maximum Youden Index. Achievement of ER between severity categories was compared using chi square tests. Time to clinical remission [CR] was compared using Kaplan-Meier survival curves. RESULTS MM-SES-CD severity categories were established as very mild/remission [score <14], mild [≥14 to <31], moderate [≥31 to <45], and severe [≥45], which were predictive of 1-year ER [50%, 30.3%, 21.7%, 8.8%, respectively, p <0.001]. Lower MM-SES-CD scores had numerically higher rates of 1-year clinical remission [CR], and time to 1-year CR was superior to those with higher scores [p = 0.0492]. MM-SES-CD thresholds for achieving 1-year ileal ER among 75 patients with isolated ileal disease were established as mild [score <14], moderate [≥14 to <33], and severe [≥33], which were predictive of 1-year ER [66.7%, 33.3%, 13.3%, respectively, p = 0.027]. CONCLUSIONS We have established numerical MM-SES-CD cut-offs that categorise endoscopic disease severity and have demonstrated that they are prognostic for 1-year ER and CR.

Abstract
BACKGROUND There is a need to better understand the positioning of biologic therapies for long-term outcomes in biologic-naïve Crohn's disease (CD). We assessed the comparative effectiveness of infliximab and ustekinumab among induction responders for 1-year outcomes. METHODS This post hoc analysis included data from 220 biologic-naïve CD participants with response to induction therapy from 2 clinical trial programs. Participants achieving 1-year clinical remission (CR) (Crohn's disease activity index <150), corticosteroid-free CR, normalization of fecal calprotectin (FC), endoscopic response (Simple Endoscopic Score for CD decrease ≥50% from baseline), and endoscopic remission (ER) (Simple Endoscopic Score for CD <3) were compared. Multivariate logistic regression evaluated the likelihood of achieving the outcomes adjusted for confounders. Propensity score matching created a cohort with similar distribution of baseline covariates. RESULTS One-year CR and corticosteroid-free CR rates were similar between infliximab-treated and ustekinumab-treated patients (CR, 66 of 110 [60.0%] vs 63 of 110 [57.3%]; adjusted odds ratio [aOR], 1.15; 95% CI, 0.67-1.98; P = .681; corticosteroid-free CR, 11 of 28 (39.3%) vs 27 of 51 [52.9%]; aOR, 0.58; 95% CI, 0.23-1.47; P = .251). Compared with ustekinumab-treated patients, infliximab-treated participants were more likely to achieve 1-year endoscopic response (43 of 92 [46.7%] vs 6 of 30 [20.0%], aOR, 3.59; 95% CI, 1.34-9.66; P = .011) and ER (31 of 92 [33.7%] vs 4 of 30 [13.3%]; aOR, 3.35; 95% CI, 1.07-10.49; P = .038). Among patients with FC ≥250 mg/kg at baseline, normalization (<250 mg/kg) at 1-year was similar between groups. Similar results were observed within the propensity matched population for all analyses. CONCLUSIONS Treatment with infliximab and ustekinumab among induction responders achieved 1-year CR with similar efficacy, but infliximab may confer greater benefit for endoscopic outcomes. Findings should be interpreted with caution as our analyses were unpowered.

Abstract
BACKGROUND The terminal ileum poses a predilection for Crohn's disease (CD) but is less susceptible to undergo healing to treatment with biologics and small molecules. This study aimed to evaluate histologic features associated with endoscopic remission (ER). METHODS This is a post hoc analysis of patients with moderately to severely active CD, defined as Crohn's disease activity index 220 to 450, and terminal ileal ulceration treated with antitumor necrosis factor (TNF)-α inhibitor adalimumab from the EXTEND trial. We studied whether baseline total Global Histologic Disease Activity Scores (GHAS), any individual histologic element, and specific immunohistochemical (IHC) markers of chronic inflammation from biopsy specimens were associated with postinduction (week 12) and maintenance (week 52) ER, defined as Simple Endoscopic Score for Crohn's Disease of 0. Multivariable logistic regression models adjusted for confounders were used to assess the relationship between histologic markers and 1-year outcomes. RESULTS Seventy-one adult patients with CD affecting the ileum were included in this analysis. Both baseline ileal GHAS scores and individual histologic components were not found to be associated with ER at weeks 12 or 52. Increased expression of interleukin-13 receptor (IL-13R) on IHC stains was associated with reduced likelihood of achieving 1-year ER (adjusted odds ratio, 0.06; 95% CI, 0.01-0.92; P = .044). No other biomarker assessed was associated with 1-year ER. CONCLUSIONS Ileal histologic disease activity and IHC activation markers of chronic mucosal inflammation were not associated with 1-year ER. However, strong staining for IL-13 receptor in the ileum was associated with reduced odds of 1-year ER using adalimumab. Mucosal cellular disease profiles might pose an opportunity to guide treatment of CD.

Abstract
BACKGROUND & AIMS Comparative effectiveness has become increasingly important to help position therapies for inflammatory bowel disease. We compared the efficacy and rapidity of onset of action of infliximab vs ustekinumab induction therapy for moderate to severe biologic-naïve Crohn's disease (CD) using patient-level data from randomized controlled trials. METHODS This was a post hoc analysis of 2 large CD clinical trial programs that included data on 420 biologic-naïve CD patients. Differences in proportions of patients achieving week 6 clinical remission, clinical response, and normalization of calprotectin were compared. Multivariate logistic regression was used to adjust for confounders. Sensitivity analysis was conducted using propensity scores to create a cohort of matched participants with similar distribution of baseline covariates. RESULTS At week 6, a comparable number of patients achieved clinical remission with infliximab compared with patients treated with ustekinumab (44.9% vs 37.9%; adjusted odds ratio [aOR], 1.22; 95% CI, 0.79-1.89). Similarly, at week 6 the clinical response rates were not significantly different (58.4% infliximab vs 54.9% ustekinumab; aOR, 1.25; 95% CI, 0.82-1.90). No significant difference was observed between treatment groups for achieving a week 6 fecal calprotectin level less than 250 mcg/L in those with increased values at baseline (42.3% infliximab vs 34.7% ustekinumab; aOR, 1.34; 95% CI, 0.79-2.28). Similar results were seen for all analyses performed within the propensity matched cohort. CONCLUSIONS Based on this post hoc analysis, infliximab and ustekinumab appear to have similar efficacy and speed of onset in patients with CD who are biologic-naïve.

Abstract
BACKGROUND & AIMS Comparative effectiveness studies are needed to help position therapies for ulcerative colitis (UC). We compared the efficacy of infliximab vs vedolizumab for moderate to severe biologic-naïve UC using patient-level data from clinical trial program data sets. METHODS This was a post hoc analysis of 3 UC clinical trial programs that included data on 795 biologic-naïve UC patients. Differences in proportions of patients achieving week 6 clinical remission (CR) and response, and 1-year CR, corticosteroid-free CR, and endoscopic remission (ER), are reported. Multivariate logistic regression was used to adjust for potential confounders. As a sensitivity analysis, propensity scores were calculated and a cohort of matched participants with similar distribution of baseline covariates was created. All analyses were intention-to-treat. RESULTS At week 6, comparable proportions of patients achieved clinical response and CR with infliximab vs vedolizumab (clinical response, 60.5% [138 of 228] vs 60.0% [340 of 567]; P = .884; and CR, 39.9% [91 of 228] vs 38.6% [219 of 567]; P = .736). Similar proportions of patients achieved 1-year CR with infliximab vs vedolizumab (39.9% [91 of 228] vs 38.6% [219 of 567]; adjusted odds ratio [aOR], 1.02; 95% CI, 0.74-1.40). Infliximab-treated patients had significantly higher rates of 1-year ER (36.0% [82 of 228] vs 25.6% [145 of 567]; aOR, 1.60; 95% CI, 1.12-2.28) and corticosteroid-free CR (29.5% [23 of 78] vs 15.0% [38 of 254]; aOR, 2.36; 95% CI, 1.27-4.39). Similar results were observed in the propensity score matched cohort. CONCLUSIONS Although infliximab and vedolizumab have similar efficacy in clinical symptom improvement, infliximab had higher rates of 1-year corticosteroid-free CR and ER in treatment of biologic-naïve UC.

Abstract
BACKGROUND AND OBJECTIVES Ulcerative colitis is highly prevalent in Canada and cost-effective ulcerative colitis therapies are warranted. Vedolizumab subcutaneous (SC) formulation was recently approved for ulcerative colitis maintenance therapy. We assessed vedolizumab SC cost effectiveness vs conventional and advanced therapeutics in patients with moderately to severely active ulcerative colitis from a Canadian public healthcare payer perspective. METHODS A hybrid decision tree/Markov model was developed to evaluate vedolizumab SC costs, quality-adjusted life-years, and cost effectiveness vs conventional therapy, adalimumab SC, infliximab intravenous, golimumab SC, tofacitinib, ustekinumab SC, and vedolizumab intravenous. This model predicts the number of patients achieving clinical response and remission after treatment induction, and sustained benefit during maintenance treatment. To account for statistical uncertainties, the base-case analysis was conducted in a probabilistic manner. Scenario analyses examined the impact of previous treatment with anti-tumor necrosis factor agents, dose escalation, loss of efficacy, and treatment adherence. RESULTS In the base-case analysis, conventional therapy was the most cost-effective therapeutic option in the overall population. Vedolizumab SC was cost effective and dominant compared with other advanced therapies (adalimumab, golimumab, infliximab, tofacitinib 5 mg, ustekinumab, and vedolizumab intravenous). The annual vedolizumab SC cost per patient was reduced vs ustekinumab SC, tofacitinib 5 mg, vedolizumab intravenous, and golimumab SC by $47,024, $3251, $2120, and $2004 (Canadian dollars), respectively, and exceeded that of infliximab, adalimumab, and conventional therapy by $582, $3293, and $41,024, respectively. Among the treatments, vedolizumab SC generated the highest quality-adjusted life-years overall (14.21), which translated into the best incremental cost per quality-adjusted life-years gained over conventional therapy in the overall population ($109,374) and in anti-tumor necrosis factor-naïve and anti-tumor necrosis factor-experienced patients ($41,658/$114,287). CONCLUSIONS Conventional therapy offered the most cost-effective therapeutic option followed by vedolizumab SC. Based on a $50,000/quality-adjusted life-year threshold, vedolizumab was cost effective in anti-tumor necrosis factor-naïve patients but not the overall population also when compared to conventional therapy.

Abstract
BACKGROUND We compared the Simple Endoscopic Score for Crohn's Disease (SES-CD) and Modified Multiplied SES-CD (MM-SES-CD) scores with the Rutgeerts score for predicting clinical recurrence (CR) of postoperative Crohn's disease (CD). METHODS This post hoc analysis of the prospective, multicenter, randomized, double-blind, placebo-controlled trial comparing remicade and placebo in the prevention of recurrence in Crohn's disease patients undergoing surgical resection who are at an increased risk of recurrence (PREVENT) study used receiver operating characteristic curve analyses to compare the Rutgeerts, SES-CD, and MM-SES-CD scores at week 76 for subsequent CR by week 104 in 208 participants. Multivariate logistic regression models evaluated cutoffs for the odds of experiencing CR by week 104, after adjustment for confounders. CR was defined as Crohn's Disease Activity Index score ≥200 and ≥70-point increase from baseline (or development of fistulas, abscesses, or treatment failure) and endoscopic recurrence by week 104, defined as Rutgeerts score ≥i2. RESULTS The week 76 Rutgeerts score predicted CR by week 104 with fair accuracy (area under the receiver-operating characteristic curve [AUC], 0.74; 95% confidence interval [CI], 0.65-0.83), which was similar to the SES-CD ileum score (AUC, 0.72; 95% CI, 0.64-0.80) and the MM-SES-CD ileum score (AUC, 0.72; 95% CI, 0.63-0.80). Compared with cutoffs by the other scores, the MM-SES-CD total score ≥26 at week 76 had the highest odds ratio to predict CR by week 104. Patients with a week 76 MM-SES-CD total score ≥26 were 4.41 times (95% CI, 2.06-9.43, P < .001) more likely to have CR by week 104 compared with those with an MM-SES-CD total score <26. CONCLUSIONS The SES-CD and MM-SES-CD perform similarly to the Rutgeerts score for predicting subsequent CR of postoperative CD. The MM-SES-CD threshold of ≥26 was predictive of postoperative CR. Clinicians and trialists could consider using the SES-CD or MM-SES-CD to assess postoperative CD given their ability to capture colonic disease recurrence and predict CR.

Abstract
BACKGROUND It is unclear whether improvement in patient-reported outcomes (PROs) relative to baseline symptom burden in Crohn's disease (CD) is associated with subsequent endoscopic remission. AIM To evaluate the relationship between dominant PRO resolution post-induction and achievement of clinical and endoscopic remission. METHODS This post-hoc analysis of clinical trial data from 251 participants evaluated the relationship between the resolution of the dominant PRO (most severely elevated baseline PRO) or clinical response (CDAI ≥100 reduction) after induction therapy with biologics (post-induction) and 1-year clinical remission (CDAI <150) and/or endoscopic remission (SES-CD <3). Multivariate logistic regression models evaluated the relationship between post-induction-dominant PRO resolution and 1-year outcomes adjusted for confounders. RESULTS Participants with dominant PRO resolution post-induction had higher odds of combined endoscopic and clinical remission compared to those without resolution (aOR: 1.94 [95% CI: 1.01-3.74], P = 0.047). Combining dominant PRO resolution with post-induction endoscopic response (SES-CD ≥50% reduction) was associated with higher odds of 1-year endoscopic and clinical remission (aOR: 6.89 [95% CI: 1.65-28.72], P = 0.008). Clinical and PRO2 response (≥30% decrease in stool frequency and/or ≥30% decrease in abdominal pain score and both not worse than baseline) at post-induction did not predict these outcomes. No significant differences were observed with 1-year endoscopic remission for post-induction-dominant PRO resolution, clinical or PRO2 response. CONCLUSIONS Post-induction resolution of dominant PRO, but not clinical or PRO2 response, was strongly associated with 1-year endoscopic and clinical remission. Resolution of dominant baseline PRO after induction therapy may be informative for 1-year outcomes. Further validation is required.

Abstract
BACKGROUND & AIMS The prognostic value of histologic scores, grades, and individual histologic subcomponents, alone or in combination with endoscopy, for predicting endoscopic improvement (EI) and histoendoscopic mucosal improvement (HEMI) during maintenance therapy in ulcerative colitis remains uncertain. METHODS We performed a post hoc analysis of participants from the VARSITY trial (n = 734 with histology). Receiver operating characteristic and multivariate logistic regression analyses were performed to assess whether baseline and/or week 14 assessments for the Robarts Histopathology Index, Geboes score, individual histologic subcomponents, and baseline disease characteristics, including endoscopic severity and biomarkers, could predict the achievement of EI and HEMI at week 52. RESULTS Changes in epithelial neutrophil involvement from baseline to week 14 had the best performance for predicting week 52 EI (area under the curve, 0.83; 95 % confidence interval [CI], 0.74-0.91) and HEMI (area under the curve, 0.85; 95 % CI, 0.76-0.94). On multivariate analyses, improvement of neutrophils in the epithelium was the only histologic parameter associated with increased odds of week 52 EI (odds ratio, 3.63; 95 % CI, 1.45-9.08; P = .0059) and HEMI (odds ratio, 6.88; 95 % CI, 3.29-14.36; P < .0001). Patients with more than 50 % of crypts involved with neutrophils at week 14 were significantly less likely to achieve week 52 HEMI irrespective of week 14 Mayo endoscopic scores (week 14 Mayo endoscopic score of 2-3: 9.9 % vs 22.4 %; P = .001; week 14 Mayo endoscopic score of 0-1: 33 % vs 62.4 %; P = .044). CONCLUSIONS Our results on epithelial neutrophilic infiltrate after induction therapy as the only independent predictor for achievement of maintenance EI or HEMI helps clarify the clinical relevance of measuring histologic disease activity in ulcerative colitis. Epithelial neutrophilic infiltrate poses a means to stratify patients according to their likelihood of response to biologic treatment.

Abstract
Objectives With the increased prevalence of childhood-onset inflammatory bowel disease (IBD), there is a greater need for a planned transition process for adolescents and young adults (AYA). The Canadian IBD Transition Network and Crohn’s and Colitis Canada joined in collaborative efforts to describe a set of care consensus statements to provide a framework for transitioning AYA from pediatric to adult care. Methods Consensus statements were drafted after focus group meetings and literature reviews. An expert panel consisting of 20 IBD physicians, nurses, surgeon, adolescent medicine physician, as well as patient and caregiver representatives met, discussed and systematically voted. The consensus was reached when greater than 75% of members voted in agreement. When greater than 75% of members rated strong support, the statement was rendered a strong recommendation, suggesting that a clinician should implement the statement for all or most of their clinical practice. Results The Canadian expert panel generated 15 consensus statements (9 strong and 6 weak recommendations). Areas of focus of the statements included: transition program implementation, key stakeholders, areas of potential need and gaps in the research. Conclusions These consensus statements provide a framework for the transition process. The quality of evidence for these statements was generally low, highlighting the need for further controlled studies to investigate and better define effective strategies for transition in pediatric to adult IBD care.

Abstract
BACKGROUND & AIMS We have previously validated a clinical decision support tool (CDST) (vedolizumab CDST [VDZ-CDST]) for clinical and endoscopic remission with VDZ in ulcerative colitis (UC). We aim to expand the validation for predicting histoendoscopic mucosal improvement (HEMI) with VDZ vs adalimumab (ADA). METHODS In a post hoc analysis of a clinical trial for VDZ vs ADA in moderate to severe UC (VARSITY trial; NCT02497469), comparative accuracy was evaluated for the VDZ-CDST among an external validation cohort of VDZ- and ADA-treated patients for week 52 HEMI (Mayo endoscopic subscore 0-1 and Geboes score <3.2). Comparative effectiveness of VDZ and ADA was assessed after stratifying the cohort by baseline probability of response to VDZ using the VDZ-CDST. RESULTS A total of 419 patients were included. The majority of patients enrolled in the VARSITY trial had a high (61%) or intermediate (29%) baseline predicted probability of response to VDZ. The baseline VDZ-CDST score was significantly more likely to predict week 52 HEMI for VDZ (area under the curve , 0.712; 95% confidence interval, 0.636-0.787) relative to ADA-treated patients (area under the curve, 0.538; 95% confidence interval, 0.377-0.700; P < .001 for AUC comparison). A significant (P < .001) association was observed between the VDZ-CDST and measured VDZ drug exposure over 52 weeks. Superiority of VDZ to ADA was only observed in patients with a high baseline predicted probability of response to VDZ. CONCLUSIONS Superiority of VDZ to ADA is dependent on baseline probability of response, and a VDZ-CDST is capable of identifying UC patients most appropriate for VDZ vs ADA.

Abstract
Background Fecal microbiota transplantation (FMT) is a promising experimental therapy for ulcerative colitis (UC), yet patient acceptance remains poorly understood. Aims The aim of this study was to explore perceptions and experiences of adult patients who received FMT for UC. Methods This study used a qualitative descriptive design with thematic content analysis. Patients who were approached for enrollment in a clinical trial (NCT02606032) were invited to participate in face-to-face semistructured interviews. Two groups were interviewed: those who chose to pursue FMT and those who declined FMT. Non-FMT patients were interviewed once; FMT patients were interviewed twice at pre- and post-treatment. Results Nine FMT patients (78% female, average age 46.7 years old) and eight non-FMT patients (50% female, average age 39.5 years old) were enrolled. Pretreatment themes included FMT as a natural therapy, external barriers to pursuing FMT, concerns with FMT and factors influencing the decision to pursue FMT. While both groups generally perceived FMT as a natural therapy, pre-FMT patients showed greater acceptance of alternative medicine. Both groups demonstrated poor understanding and similar initial concerns with product cleanliness. Pre-FMT patients were motivated to pursue FMT by feelings of last resort. Post-FMT themes included therapeutic impact of FMT and psychosocial impact of FMT. Post-FMT patients reported overall satisfaction and a unanimous preference for FMT over conventional medications. Conclusion This is the first study to assess adult patient perceptions and real-life experiences with FMT for the treatment of UC. By improving patient education, we may achieve greater acceptance of FMT.

Abstract
The SARS-CoV-2 pandemic has had a profound impact on inflammatory bowel disease (IBD) health care delivery. The implementation of necessary public health restrictions has restricted access to medications, procedures and surgeries throughout the pandemic, catalyzing widespread change in how IBD care is delivered. Rapid large-scale implementation of virtual care modalities has been shown to be feasible and acceptable for the majority of individuals with IBD and health care providers. The SARS-CoV-2 pandemic has exacerbated pre-existing barriers to accessing high-quality, multidisciplinary IBD care that addresses health care needs holistically. Continued implementation and evaluation of both synchronous and asynchronous eHealthcare modalities are required now and in the future in order to determine how best to incorporate these modalities into patient-centred, collaborative care models. Resources must be dedicated to studies that evaluate the feasibility, acceptability and effectiveness of eHealth-enhanced models of IBD care to improve efficiency and cost-effectiveness, while increasing quality of life for persons living with IBD. Crohn's and Colitis Canada will continue to play a major leadership role in advocating for the health care delivery models that improve the quality of life for persons living with IBD.

Abstract
The prevalence of inflammatory bowel diseases (IBD), Crohn’s disease and ulcerative colitis, in Canada, is over 0.75% in 2021. Many individuals with IBD are immunocompromised. Consequently, the World Health Organization’s declaration of a global pandemic uniquely impacted those with IBD. Crohn’s and Colitis Canada (CCC) formed the COVID-19 and IBD Taskforce to provide evidence-based guidance during the pandemic to individuals with IBD and their families. The Taskforce met regularly through the course of the pandemic, synthesizing available information on the impact of COVID-19 on IBD. At first, the information was extrapolated from expert consensus guidelines, but eventually, recommendations were adapted for an international registry of worldwide cases of COVID-19 in people with IBD. The task force launched a knowledge translation initiative consisting of a webinar series and online resources to communicate information directly to the IBD community. Taskforce recommendations were posted to CCC’s website and included guidance such as risk stratification, management of immunosuppressant medications, physical distancing, and mental health. A weekly webinar series communicated critical information directly to the IBD community. During the pandemic, traffic to CCC’s website increased with 484,755 unique views of the COVID-19 webpages and 126,187 views of the 23 webinars, including their video clips. CCC’s COVID-19 and IBD Taskforce provided critical guidance to the IBD community as the pandemic emerged, the nation underwent a lockdown, the economy reopened, and the second wave ensued. By integrating public health guidance through the unique prism of a vulnerable population, CCC’s knowledge translation platform informed and protected the IBD community.

Abstract
Persons with inflammatory bowel disease (IBD) make up more than 0.75% of the Canadian population in 2021. Early in the COVID-19 pandemic, individuals with IBD, particularly those on immunosuppressive therapies, were concerned that their health status may place them at higher risk of contracting COVID-19 or experiencing more severe disease course if infected with SARS-CoV-2. In response, Crohn’s and Colitis Canada developed the COVID-19 and IBD Taskforce in March 2020 to rapidly synthesize the evolving knowledge of COVID-19 as relevant to Canadians with IBD. The Taskforce communicated expert information directly to the Canadian IBD community through online tools and a webinar series. In order to understand the full impact of COVID-19 on the IBD community, Crohn’s and Colitis Canada commissioned a policy report that was informed through a systematic literature review and synthesized across working groups along the following domains: Epidemiology, Children and Expectant Mothers with IBD, Seniors with IBD, Mental Health, Risk Factors and Medications, Vaccines, and Healthcare Delivery during the Pandemic and the Future Model of IBD Care. This report from Canadian physicians, researchers, and IBD community representatives highlights the physical, mental, and health systems impact of COVID-19 on the entire spectrum of the IBD community, including children, adolescents, adults, seniors, and pregnant people with IBD. This executive summary provides an overview of the crucial information from each of the chapters of the policy report, supplemented with additional information made available through Crohn’s and Colitis Canada’s webinar-based knowledge translation platform.

Abstract
Autophagy, an essential intracellular recycling process, is linked to the pathogenesis of various diseases including Crohn’s disease (CD). Factors that lead to the development of impaired autophagy during intestinal inflammation remain largely unexplored. Here, we report the impact of the interaction between serotonin [5-hydroxytryptamine;(5-HT)] and autophagy in colitis in mouse and human studies. In mice, increased gut 5-HT inhibited autophagy and led to enhanced colitis susceptibility. Reciprocally, mice with reduced 5-HT exhibited up-regulated autophagy via the mammalian target of rapamycin pathway, which resulted in significantly decreased colitis. Deletion of autophagy gene, Atg7, in an epithelial-specific manner, in concert with reduced 5-HT, promoted the development of a colitogenic microbiota and abolished the protective effects conferred by reduced 5-HT. Notably, in control and patient peripheral blood mononuclear cells, we uncovered that 5-HT treatment inhibited autophagy. Our findings suggest 5-HT as a previously unidentified therapeutic target in intestinal inflammatory disorders such as CD that exhibits dysregulated autophagy.

Abstract
BACKGROUND AND AIMS This study evaluated the minimal clinically important short-term improvement in the Modified Multiplier Simple Endoscopic Score for crohn's Disease [MM-SES-CD], a novel modified scoring system of the SES-CD, which reliably predicted 1-year endoscopic remission [ER]. METHODS This post-hoc analysis of two CD clinical trial programmes pooled data of 198 participants with baseline ulcers and SES-CD ≥3, who had baseline, post-induction [8-12 weeks], and 1-year endoscopic assessments. Different cut-off values for endoscopic response were evaluated using receiver operating characteristic [ROC] curves, positive likelihood ratios [PLR], and negative likelihood ratios [NLR]. ER [SES-CD <3] was the binary classifier in all cases. A distribution of cut-offs minimising NLR and maximising PLR was created with 10 000 bootstrapped resamples. An optimal cut-point for low and high probability of 1-year ER was determined based on the maximum Youden Index. RESULTS MM-SES-CD ≥40% reduction from baseline was selected as the cut-off maximising PLR and minimising NLR. Among 7.6% [15/198] participants achieving this cut-off post-induction, 1-year ER was 46.7%. One-year ER was 16.9% among those not achieving this cut-off. This threshold predicted 1-year ER with 95.0% (95% confidence interval [CI] 90.4%-97.8%) specificity and a PLR of 3.7 [95% CI 1.4-9.5], which was higher than traditional endoscopic response criteria of SES-CD ≥50% reduction [specificity 62.5%, 95% CI 54.5%-70.0%; PLR 1.9, 95% CI 1.4-2.5]. Lower thresholds of MM-SES-CD reduction also were highly specific for 1-year ER [e.g., MM-SES-CD ≥20% reduction was achieved in 19.7% of patients with 83.1% specificity]. CONCLUSIONS In CD patients, post-induction endoscopic response defined by MM-SES-CD ≥40% reduction from baseline identified patients most likely to achieve 1-year ER.

Abstract
Background Corticosteroids (CS) have been used extensively to induce remission in Crohn’s disease (CD); however, they are associated with severe side effects. We hypothesized that the administration of an exclusive enteral nutrition (EEN) formula to CS would lead to increased CD remission rates and to decreased CS-related adverse events. We proposed to undertake a pilot study comparing EEN and CS therapy to CS alone to assess decrease symptoms and inflammatory markers over 6 weeks. Aim The overall aim was to assess study feasibility based on recruitment rates and acceptability of treatment in arms involving EEN Methods The pilot study intended to recruit 100 adult patients with active CD who had been prescribed CS to induce remission as part of their care. The patients were randomized to one of three arms: (i) standard-dose CS; (ii) standard-dose CS plus EEN (Modulen 1.5 kcal); or (iii) short-course CS plus EEN. Results A total of 2009 CD patients attending gastroenterology clinics were screened from October 2018 to November 2019. Prednisone was prescribed to only 6.8% (27/399) of patients with active CD attending outpatient clinics. Of the remaining 372 patients with active CD, 34.8% (139/399) started or escalated immunosuppressant or biologics, 49.6% (198/399) underwent further investigation and 8.8% (35/399) were offered an alternative treatment (e.g., antibiotics, surgery or investigational agents in clinical trials). Only three patients were enrolled in the study (recruitment rate 11%; 3/27), and the study was terminated for poor recruitment. Conclusion The apparent decline in use of CS for treatment of CD has implications for CS use as an entry criterion for clinical trials.

Abstract
BACKGROUND AND AIMS There is paucity of evidence on the reversibility of Crohn's disease [CD]-related strictures treated with therapies. We aimed to describe the clinical and endoscopic outcomes of CD patients with non-passable strictures. METHODS This was a post-hoc analysis of three large CD clinical trial programmes examining outcomes with infliximab, ustekinumab, and azathioprine, which included data on 576 patients including 105 with non-passable strictures and 45 with passable strictures, as measured using the Simple Endoscopic Score for Crohn's Disease [SES-CD]. The impact of non-passable strictures on achieving clinical remission [CR] and endoscopic remission [ER] was assessed using multivariate logistic regression models. CR was defined as a Crohn's Disease Activity Index [CDAI] <150, clinical response as a CDAI reduction of ≥100 points, and ER as SES-CD score <3. RESULTS After 1 year of treatment, patients with non-passable strictures demonstrated the ability to achieve passable or no strictures in 62.5% of cases, with 52.4% and 37.5% attaining CR and ER, respectively. However, patients with non-passable strictures at baseline were less likely to demonstrate symptom improvement compared with those with passable or no strictures, with reduced odds of 1-year CR (adjusted odds ratio [aOR] 0.17, 95% CI 0.03-0.99, p = 0.048). No significant differences were observed between patients with non-passable strictures at baseline and those with passable or no strictures in rates of ER [aOR 0.82, 95% CI 0.23-2.85, p = 0.751] at 1 year. CONCLUSIONS Patients with non-passable strictures can achieve symptomatic and endoscopic remission when receiving therapies used to treat CD, although they are less likely to obtain CR compared with patients without non-passable strictures. These findings support the importance of balancing the presence of non-passable strictures in trial arms.

Abstract
BACKGROUND AND AIM Crohn's disease (CD) patients who previously failed anti-tumor necrosis factor (TNF) therapy are at higher risk of treatment failure with subsequent biologics. This study aims to determine the effectiveness and safety of higher maintenance dose regimens of adalimumab compared with standard doses in CD patients who failed anti-TNF. METHODS In this retrospective observational study, CD patients who failed anti-TNF and received adalimumab were categorized according to their post-induction maintenance regimen; 40 mg subcutaneous (sc) weekly or 80 mg sc every other week were defined as a high-dose (HD) maintenance regimen, and 40 mg sc every other week was defined as a standard-dose (SD) maintenance regimen. The primary outcome was time to treatment failure. Cox proportional hazards regression was used to adjust for confounders. Sensitivity analysis was conducted using propensity scores to create a cohort of matched participants with similar distribution of baseline covariates. RESULTS Forty patients started on HD regimens following induction, and 77 patients received the SD regimen. The median time to failure in the HD group was 6.6 years (interquartile range [IQR] 4.0-9.6) and 3.0 years (IQR 0.9-9.4) in the SD group (log-rank test P = 0.006). Patients on HD adalimumab had a lower hazard rate of treatment failure (hazard ratio: 0.27; 95% confidence interval [0.12, 0.62]; P = 0.002) compared with SD patients. No difference in adverse events was identified between groups (30% vs 31.2%, P = 1.0). Results were similar in the propensity score-matched cohort. CONCLUSIONS High-dose maintenance regimens were associated with longer time-to-failure as compared with SD regimens in CD patient who failed anti-TNF.

Abstract
BACKGROUND AND AIM Vedolizumab is a novel monoclonal antibody used in patients with inflammatory bowel disease, often affecting women of child-bearing age. We aimed to compare maternal and fetal adverse outcomes in pregnancies of women with inflammatory bowel disease exposed to vedolizumab versus those on other treatment. METHODS We performed a systematic literature search through December 2020 looking for studies including outcomes from pregnancies of female inflammatory bowel disease patients treated with vedolizumab. Our primary outcome was a composite of adverse pregnancy-related events in pregnancies of female patients on vedolizumab compared with those of disease-matched controls on other medication regimens. Events of interest included preterm births, early loss of pregnancy, late fetal death, elective termination of pregnancy, and congenital anomalies. RESULTS Four studies were included in our review meeting criteria for our primary analysis. Compared with those with no vedolizumab exposure, pregnancies with vedolizumab exposure had an increase in overall adverse pregnancy-related outcomes (odds ratio [OR] 2.18, 95% confidence interval [CI], 1.52-3.13). The vedolizumab group also had increased preterm births (OR 2.16, 95% CI, 1.28-3.66), and early loss of pregnancies (OR 1.79, 95% CI, 1.06-3.01) but no difference in number of live births (OR 0.60, 95%CI, 0.36-1.00), or congenital malformations (OR 1.56, 95% CI, 0.56-4.37). CONCLUSIONS Our systematic review highlights possible concern with the general safety of vedolizumab in pregnancy, as an increase in overall total unfavorable outcomes was observed. Premature births and early loss of pregnancy were also more prevalent in pregnant female patients on vedolizumab. It is possible these findings are confounded by disease activity, and further prospective cohort studies of vedolizumab and pregnancy outcomes are warranted.
