Summary Background Filgotinib 200 mg (FIL200) is an approved treatment for adults with moderately to severely active ulcerative colitis (UC). Aim To report integrated safety data from the phase 2b/3 SELECTION study (NCT02914522) and its ongoing long‐term extension study SELECTIONLTE (NCT02914535). Methods Safety outcomes were analysed in adults with moderately to severely active UC who received FIL200, filgotinib 100 mg (FIL100) or placebo once daily throughout the 11‐week SELECTION induction study, the 47‐week SELECTION maintenance study (if applicable) and SELECTIONLTE (if applicable). Exposure‐adjusted incidence rates (EAIRs) per 100 censored patient‐years of exposure with 95% confidence intervals were reported for treatment‐emergent adverse events (AEs). Certain AE data were presented in subgroups, including age and prior biologic exposure status. Results This interim analysis included 1348 patients representing 3326.2 patient‐years of exposure. Baseline characteristics of patients entering SELECTION were similar across treatment groups. EAIRs for serious infection, thromboembolic events and major adverse cardiovascular events (MACE) were consistently low across treatment groups. Most patients with MACE had cardiovascular risk factors. The EAIR for herpes zoster was numerically higher for FIL200 than for placebo. Infection incidences were numerically higher in biologic‐experienced than biologic‐naive patients. Higher incidences of certain AEs in patients 65 years of age or older were as expected. Four deaths occurred, including three cardiovascular deaths, none of which was considered related to filgotinib. Conclusion FIL200 and FIL100 were well tolerated with no unexpected safety signals in patients with moderately to severely active UC, regardless of previous biologic exposure or age.

Abstract Background Vedolizumab, an anti-α4β7 integrin approved for intravenous (IV) treatment of moderately to severely active ulcerative colitis (UC) and Crohn’s disease (CD), was evaluated as a subcutaneous (SC) formulation in maintenance therapy for UC and CD in phase 3 VISIBLE 1, 2, and open-label extension studies, and recently approved in Europe, Australia, and Canada. Our aim was to evaluate efficacy and safety of IV and SC vedolizumab in clinically relevant UC and CD scenarios. Methods Post hoc data analyses from VISIBLE trials examined: (1) whether baseline characteristics predict clinical response to 2 vs 3 IV vedolizumab induction doses; (2) efficacy and safety of switching during maintenance vedolizumab IV to SC in patients with UC; (3) vedolizumab SC after treatment interruption of 1–46 weeks; (4) increasing dose frequency of vedolizumab SC from every 2 weeks (Q2W) to every week (QW) after disease worsening. Results No baseline characteristics were identified as strong predictors of response to 2 vs 3 vedolizumab infusions. Most patients achieved clinical response after 2 or 3 doses of IV vedolizumab maintained with SC treatment. Clinical remission and response rates were maintained in patients transitioned from maintenance vedolizumab IV to SC treatment. Of patients with UC, ≥75% achieved response following resumption after dose interruption. Escalation to QW dosing resulted in ≥45% of patients regaining response after loss while receiving vedolizumab Q2W. Conclusions Clinical real-world scenarios with vedolizumab SC were reviewed using VISIBLE studies data. Vedolizumab SC provides an additional dosing option for patients with UC and CD.

Abstract Background This study described the clinical characteristics, outcomes, and prognosis of Crohn’s disease (CD) patients with anal cancer in a tertiary referral center. Methods The electronic medical records of 35 adult CD patients, including CD of the pouch, with anal carcinoma evaluated at Mayo Clinic Rochester, Florida, or Arizona between January 1989 and August 2022 were retrospectively reviewed. Results Before cancer diagnosis, patients with pouch-related carcinoma had a shorter median duration of inflammatory bowel disease than those with anal carcinoma (10 vs 26 years). Twenty-six patients (74%) had perianal diseases or rectovaginal fistula, and 35% had a history of human papillomavirus infection. Twenty-one patients (60%) were diagnosed with cancer by anal examination under anesthesia (EUA). More than half of adenocarcinomas were mucinous. Sixteen patients (47%) were American Joint Committee on Cancer (AJCC) Tumor Nodes Metastasis (TNM) stage 3, and 83% were treated by surgery. At last follow-up, 57% of patients were alive without cancer. The 1-, 3- and 5-year overall survival rates were 93.8% (95% confidence interval [CI], 85.7%-100%), 71.5% (95% CI, 56.4%-90.7%), and 67.7% (95% CI, 51.2%-87.7%), respectively. Advanced AJCC TNM stage (hazard ratio, 3.20 per stage; 95% CI, 1.05-9.72; P = .040) was significantly associated with increased risk of death, whereas the period of cancer diagnosis in 2011-2022 (HR, relative to 1989-2000, 0.16; 95% CI, 0.04-0.72; P = .017) was significantly related to decreased risk of death. Conclusions Anal and pouch-related carcinomas were rare complications of CD, and long-standing perianal diseases were an important risk factor. Anal EUA improved the diagnostic yield. Newer cancer treatment strategies and surgery were associated with excellent survival outcome.

AbstractBackgroundThis retrospective study gathered medical/pharmacy claims data on patients with inflammatory bowel disease (IBD) between January 01, 2000 and March 31, 2019 from the IBM MarketScan commercial claims database to assess the real-world impact of fatigue on healthcare costs in patients newly diagnosed with IBD.MethodsEligible participants were ≥18 years, newly diagnosed with IBD (≥2 separate claims), and had ≥12 months of continuous database enrollment before and after fatigue diagnosis. The date of fatigue diagnosis was the index date; participants were followed for 12 months post-index. Patients with (cases) or without (controls) fatigue were matched 1:1 by propensity score matching. Patients with evidence of prior IBD diagnosis/treatment, or those with a chronic disease other than IBD wherein fatigue is the primary symptom, were excluded. Healthcare resource utilization (HCRU), including hospitalizations, inpatient and outpatient visits, and associated costs were compared between cases and controls.ResultsMatched IBD cohorts (21 321 cases/21 321 controls) were identified (42% Crohn’s disease [CD] and 58% ulcerative colitis [UC]) with similar baseline characteristics (average age: 46 years; 60% female). Cases versus controls had significantly more all-cause outpatient visits (incidence rate ratio [IRR], 95% confidence intervals [95% CI]: 1.64 [1.61, 1.67], P < .001) and all-cause hospitalizations (IRR [95% CI]: 1.92 [1.81, 2.04], P < .001); as well as significantly higher all-cause total direct healthcare costs (mean: $24 620 vs. $15 324; P < .001). Similar findings were observed for IBD-related outcomes, as well as in CD- and UC-specific subgroups.ConclusionsPresence of fatigue is associated with an increase in HCRU and total medical costs among patients newly diagnosed with IBD.

Abstract Background Optimizing therapy and monitoring response are integral aspects of inflammatory bowel disease treatment. We conducted a systematic review and meta-analysis to determine whether serum ustekinumab trough concentrations during maintenance therapy were associated with ustekinumab treatment response in patients with inflammatory bowel disease. Methods A systematic review was performed to March 21, 2022, to identify studies using MEDLINE, EMBASE, and the Cochrane library. We included studies that reported the association between serum ustekinumab trough concentrations with clinical or endoscopic remission. Outcome measures were combined across studies using the random-effects model with an odds ratio (OR) for binary outcomes of endoscopic and clinical remission. Results We identified 14 observational studies that were included in the analysis for clinical remission (919 patients, 63% with Crohn’s disease) or endoscopic remission (290 patients, all with Crohn’s disease). Median ustekinumab trough concentrations were higher amongst individuals achieving clinical remission compared with those not achieving remission (mean difference, 1.6 ug/mL; 95% confidence interval [CI], 0.21-3.01 ug/mL). Furthermore, individuals with median serum trough concentration in the fourth quartile were significantly more likely to achieve clinical (OR, 3.61; 95% CI, 2.11-6.20) but not endoscopic remission (OR, 4.67; 95% CI, 0.86-25.19) compared with those with first quartile median trough concentrations. Conclusion Based on the results of this meta-analysis primarily relating to patients with Crohn’s disease on maintenance ustekinumab treatment, it appears that there is an association between higher ustekinumab trough concentration and clinical outcomes. Prospective studies are required to determine whether proactive dose adjustments of ustekinumab therapy provides additional clinical benefit.

Abstract Background Ileal pouch–anal anastomosis (IPAA) is the standard restorative procedure following proctocolectomy in patients with inflammatory bowel disease (IBD) who require colectomy. However, removal of the diseased colon does not eliminate the risk of pouch neoplasia. We aimed to assess the incidence of pouch neoplasia in IBD patients following IPAA. Methods All patients at a large tertiary center with International Classification of Diseases–Ninth Revision/International Classification of Diseases–Tenth Revision codes for IBD who underwent IPAA and had subsequent pouchoscopy were identified using a clinical notes search from January 1981 to February 2020. Relevant demographic, clinical, endoscopic, and histologic data were abstracted. Results In total, 1319 patients were included (43.9% women). Most had ulcerative colitis (95.2%). Out of 1319 patients, 10 (0.8%) developed neoplasia following IPAA. Neoplasia of the pouch was seen in 4 cases with neoplasia of the cuff or rectum seen in 5 cases. One patient had neoplasia of the prepouch, pouch, and cuff. Types of neoplasia included low-grade dysplasia (n = 7), high-grade dysplasia (n = 1), colorectal cancer (n = 1), and mucosa-associated lymphoid tissue lymphoma (n = 1). Presence of extensive colitis, primary sclerosing cholangitis, backwash ileitis, and rectal dysplasia at the time of IPAA were significantly associated with increased risk of pouch neoplasia. Conclusions The incidence of pouch neoplasia in IBD patients who have undergone IPAA is relatively low. Extensive colitis, primary sclerosing cholangitis, and backwash ileitis prior to IPAA and rectal dysplasia at the time of IPAA raise the risk of pouch neoplasia significantly. A limited surveillance program might be appropriate for patients with IPAA even with a history of colorectal neoplasia.

Background: Obesity is on the rise within the inflammatory bowel disease population. The impact obesity has on the natural history of Crohn’s disease (CD) is not well-understood. We aimed to describe the prevalence of obesity in a population-based cohort of newly diagnosed patients with CD, and the impact obesity had on disease phenotype and outcomes of corticosteroid use, hospitalization, intestinal resection, and development of fistulizing or penetrating disease. Materials and Methods: A chart review was performed on Olmsted County, Minnesota residents diagnosed with CD between 1970 and 2010. Data were collected on demographics, body mass index, CD location and behavior, CD-related hospitalizations, corticosteroid use, and intestinal resection. The proportion of individuals considered obese at the time of CD diagnosis was evaluated over time, and CD-associated complications were assessed with Kaplan-Meier survival analysis. Results: We identified 334 individuals diagnosed with CD between 1970 and 2010, of whom 156 (46.7%) were either overweight (27.8%) or obese (18.9%) at the time of diagnosis. The proportion of patients considered obese at the time of their diagnosis of CD increased 2-3 fold over the course of the study period. However, obesity did not have a significant impact on the future risk of corticosteroid use, hospitalization, intestinal resection, or development of penetrating and stricturing complications. Conclusions: Obesity is on the rise in patients with CD, although in this cohort, there did not appear to be any negative association with future CD-related outcomes. Further prospective studies, ideally including obesity measures such as visceral adipose tissue assessment, are warranted to understand the implications of the rising prevalence of obesity on CD outcomes.

Abstract Background The incidence of inflammatory bowel disease (IBD) has risen among Black individuals and Hispanic or Latino individuals in the USA in recent decades; however, these patients are underrepresented in clinical trials of IBD therapies. We aimed to perform a post hoc analysis of the baseline demographics and clinical characteristics in three phase 3 clinical trials of vedolizumab for ulcerative colitis (UC) to identify differences between racial and ethnic groups. Methods The baseline demographics and clinical characteristics of patients with UC who were enrolled in GEMINI 1, VARSITY, and VISIBLE 1 were pooled and stratified by race and ethnicity, which were self-reported. The inclusion criteria for these trials included adult patients with moderately to severely active UC who had a prior inadequate treatment response, loss of response, or intolerance to conventional therapies or anti-tumour necrosis factor α treatment. Data were analysed using descriptive statistics, with mean or median values calculated for continuous variables, and the number and proportion of patients reported for categorical variables. T-tests and exact tests were used to compare continuous and categorical variables, respectively, between Black and White patients and between Hispanic or Latino patients and those who were not Hispanic or Latino. Results We included 1,358 patients, of whom 1,171 (86.2%) were White, 148 (10.9%) were Asian, 14 (1.0%) were Black, and 25 (1.8%) were of multiple or unspecified racial groups (Table 1). Black patients had significantly higher mean weight (87.9 kg vs 74.8 kg, p < 0.01) and body mass index (30.5 kg/m2 vs 25.2 kg/m2, p < 0.01), but lower albumin (38.5 g/L vs 41.2 g/L, p < 0.05) and haemoglobin levels (115.5 g/L vs 126.1 g/L, p < 0.05) than White patients (Table 1). Ethnicity data were recorded for 465 patients (34.2%). Hispanic or Latino patients were shorter in height (166.6 cm vs 171.0 cm, p < 0.01) and had shorter mean disease duration (4.6 years vs 7.6 years, p < 0.01) than those who were not Hispanic or Latino (Table 2). A non-significant, but numerically greater proportion of Hispanic or Latino patients had pancolitis than those who were not Hispanic or Latino (50.0% vs 35.8%). Conclusion In this post hoc analysis of vedolizumab clinical trials, Black patients and Hispanic or Latino patients with UC had differences in certain demographic and disease characteristics versus White patients and patients who were not Hispanic or Latino, respectively. These differences may have implications for therapy. Thus, inclusion of a more diverse patient population that reflects the demographics of the general population is warranted to adequately ascertain drug efficacy across racial and ethnic groups.

Abstract Background STRIDE-II guidelines recommend endoscopic healing as an important treatment goal in Crohn’s disease (CD). This study evaluated the association of achieving endoscopic outcomes at week 12 and clinical outcomes at week 52 of maintenance treatment in patients with CD treated with upadacitinib (UPA). Methods This post-hoc analysis evaluated data from two Phase 3 UPA induction (U-EXCEED and U-EXCEL) trials and the maintenance (U-ENDURE) trial in patients with moderate to severe CD. Patients who responded to 12-week induction therapy with UPA (45 mg per day [QD]) in U-EXCEED or U-EXCEL and received maintenance therapy with UPA (15 or 30 mg QD) up to 52 weeks in U-ENDURE were included. Clinical outcomes (CD activity index [CDAI] remission, CDAI response, steroid-free CDAI remission, high sensitivity C-reactive protein [hs-CRP] level ≤5 mg/L, and fecal calprotectin level [F-cal] ≤250 mcg/g), were evaluated at week 52 and compared between patients who achieved endoscopic response, endoscopic remission and ulcer-free endoscopy (absence of ulceration) at week 12 and those who did not using Chi-square test. Results Of 337 clinical responders included in the analyses, 152 (45.1%), 87 (25.8%), and 75 (22.3%) patients achieved endoscopic response, endoscopic remission, and ulcer-free endoscopy, respectively, at the end of induction. Significantly more patients who achieved an endoscopic response at end of induction (vs those who did not) attained clinical outcomes at week 52 (CDAI remission, 52.0% vs 34.6%; CDAI response, 54.6% vs 39.5%; hsCRP ≤5 mg/L, 52.0% vs 30.8%; and F-cal ≤250 mcg/g, 42.1% vs 21.6%; P≤0.01, Table 1). Patients who achieved an endoscopic response vs those who did not at end of induction were also more likely to attain steroid-free CDAI remission (50.0% vs 30.9%) at week 52, (P≤0.05, Table 1). Similar findings were observed in patients who achieved endoscopic remission vs those who did not at end of induction (P≤0.01, Table 1). Significantly more patients attained CDAI remission (58.7% vs 37.7%), CDAI response (58.7% vs 42.7%), hsCRP ≤5 mg/L (58.7% vs 35.0%) and F-cal ≤250 mcg/g (50.7% vs 25.0%) at week 52, among patients who achieved ulcer-free endoscopy vs those who did not at end of induction (P≤0.05, Table 1). Conclusion Achieving endoscopic outcomes at end of induction is associated with meaningful improvement in symptoms and inflammatory biomarkers at 52 weeks for patients with CD receiving UPA therapy. Endoscopic remission and ulcer-free endoscopy are associated with very similar long-term benefits.
