Abstract Background Global data demonstrate an inverse relationship between hospital ileoanal pouch volume and adverse outcomes, highlighting the need for quality metrics for this technically demanding procedure.1-4 Currently, there are no standardised quality indicators to define high-quality pouch surgery. This study aimed to establish international consensus on key performance indicators (KPIs) in pouch surgery. Methods A modified Delphi process was conducted among an international, multidisciplinary panel of experts. Participants were identified through professional networks, literature review, and direct email invitation; additional participants recruited via a snowball sampling approach over one month. Candidate KPIs were generated from literature review and expert input across 5 domains. Each item was rated on a 9-point Likert scale (1 = not important, 9 = critically important); consensus was predefined as ≥ 80% of respondents rating an item 7–9. Items not reaching consensus were re-rated in a second round following anonymized group feedback. Results Round 1 included 312 participants from 37 countries. Demographics (Table 1): 53% were age 45 years, 35.2% were female, and included surgeons (68.6%) and gastroenterologists (31.1%). Most (76.6%) practice at academic or university hospitals, with a median of 11 (5–17) years in practise; 78.9% perform >1 pouchoscopy per month, and 39.5% of surgeons perform 5 pouches/year. Respondents’ regions included North America (51%), Europe (26%), Oceania (9%), Asia (6%), Latin America (4%), and the Middle East/Africa (4%). Seven (18%) countries (Denmark, Lithuania, Malaysia, Norway, United Arab Emirates, Sweden, and Switzerland) reported pouch surgery is already centralised, while 70.6% agreed pouch centralisation should be implemented. Cost/logistics and professional autonomy were the most important barriers to centralisation, whereas capacity and training exposure were least important. Overall, 37/59 (62.7%) candidate KPIs reached consensus after Round 1. The Round 2 response rate was 61%, and 2 additional KPIs reached consensus (preop ileitis and long-term risk of pouchitis). Additionally, 14 of 25 (56%) informed consent items reached consensus, and 64% of respondents felt informed consent for pouch surgery requires 2 or more office visits. Consensus items were used to populate a KPIPS Checklist (Figure 1). Conclusion Through an international Delphi process, the KPIPS study identified a consensus-derived set of key performance indicators to measure quality in pouch surgery. These quality metrics provide a foundation for benchmarking outcomes and represent a critical step towards centralization and the development of designated pouch centres of excellence to improve global standards of care for pouch patients.

SummaryBackgroundFilgotinib, an oral, once‐daily, Janus kinase 1 preferential inhibitor, is an approved treatment for moderately to severely active ulcerative colitis.AimsThe aim of this study is to assess the safety and efficacy of continued filgotinib therapy over ~4 years in the long‐term extension of the phase 2b/3 SELECTION trial (SELECTIONLTE; NCT02914535).MethodsIn this interim analysis of SELECTIONLTE, SELECTION completers (week 10 responders to filgotinib who completed the maintenance study) continued their assigned treatment (double‐blind filgotinib 200 mg [FIL200] or filgotinib 100 mg) and SELECTION week 10 non‐responders received open‐label FIL200. We assessed safety by adverse events (AEs), and efficacy by partial Mayo Clinic Score (pMCS), inflammatory biomarkers and health‐related quality of life (HRQoL). We compared safety and efficacy between achievers and non‐achievers of a multi‐component endpoint, comprehensive disease control (CDC), comprising symptomatic, endoscopic, inflammatory biomarker and HRQoL improvements.ResultsData for completers (n = 250) and non‐responders (n = 372) were reported for ≤202 weeks. AE occurrences were low and consistent with previous analyses. The as‐observed proportion of FIL200‐treated patients in pMCS, biomarker and HRQoL remission during SELECTIONLTE remained high among completers (week 144: 80.0%, 86.4% and 86.0%, respectively) and increased among non‐responders (week 192: 62.1%, 76.7% and 59.3%, respectively). Significantly higher proportions of CDC achievers at SELECTION week 58 achieved pMCS, IBDQ and corticosteroid‐free pMCS remission than non‐achievers, up to LTE week 96.ConclusionsFilgotinib induced and maintained symptomatic remission and improved HRQoL over 4 years. Safety results showed a proven long‐term benefit–risk profile. FIL200‐treated CDC achievers had better long‐term outcomes than non‐achievers.

Importance The clinical effects of risankizumab (a monoclonal antibody that selectively targets the p19 subunit of IL-23) for the treatment of ulcerative colitis are unknown. Objective To evaluate the efficacy and safety of risankizumab when administered as an induction and a maintenance therapy for patients with ulcerative colitis. Design, Setting, and Participants Two phase 3 randomized clinical trials were conducted. The induction trial was conducted at 261 clinical centers (in 41 countries) and enrolled 977 patients from November 5, 2020, to August 4, 2022 (final follow-up on May 16, 2023). The maintenance trial was conducted at 238 clinical centers (in 37 countries) and enrolled 754 patients from August 28, 2018, to March 30, 2022 (final follow-up on April 11, 2023). Eligible patients had moderately to severely active ulcerative colitis; a history of intolerance or inadequate response to 1 or more conventional therapies, advanced therapies, or both types of therapies; and no prior exposure to risankizumab. Interventions For the induction trial, patients were randomized 2:1 to receive 1200 mg of risankizumab or placebo administered intravenously at weeks 0, 4, and 8. For the maintenance trial, patients with a clinical response (determined using the adapted Mayo score) after intravenous treatment with risankizumab were randomized 1:1:1 to receive subcutaneous treatment with 180 mg or 360 mg of risankizumab or placebo (no longer receiving risankizumab) every 8 weeks for 52 weeks. Main Outcomes and Measures The primary outcome was clinical remission (stool frequency score ≤1 and not greater than baseline, rectal bleeding score of 0, and endoscopic subscore ≤1 without friability) at week 12 for the induction trial and at week 52 for the maintenance trial. Results Among the 975 patients analyzed in the induction trial (aged 42.1 [SD, 13.8] years; 586/973 [60.1%] were male; and 677 [69.6%] were White), the clinical remission rates at week 12 were 132/650 (20.3%) for 1200 mg of risankizumab and 20/325 (6.2%) for placebo (adjusted between-group difference, 14.0% [95% CI, 10.0%-18.0%], P < .001). Among the 548 patients analyzed in the maintenance trial (aged 40.9 [SD, 14.0] years; 313 [57.1%] were male; and 407 [74.3%] were White), the clinical remission rates at week 52 were 72/179 (40.2%) for 180 mg of risankizumab, 70/186 (37.6%) for 360 mg of risankizumab, and 46/183 (25.1%) for placebo (adjusted between-group difference for 180 mg of risankizumab vs placebo, 16.3% [97.5% CI, 6.1%-26.6%], P < .001; adjusted between-group difference for 360 mg of risankizumab vs placebo, 14.2% [97.5% CI, 4.0%-24.5%], P = .002). No new safety risks were detected in the treatment groups. Conclusion and Relevance Compared with placebo, risankizumab improved clinical remission rates in an induction trial and in a maintenance trial for patients with moderately to severely active ulcerative colitis. Further study is needed to identify benefits beyond the 52-week follow-up. Trial Registration ClinicalTrials.gov Identifiers: NCT03398148 and NCT03398135

Abstract Background Filgotinib (FIL), an oral, once-daily, Janus kinase 1 inhibitor, was approved for Ulcerative Colitis (UC) treatment after the phase 2b/3 SELECTION trial (NCT02914522). In SELECTION, a greater proportion of FIL200 mg (FIL200)-treated than placebo-treated patients achieved comprehensive disease control (CDC), a stringent multi-component endpoint. We examined the long-term outcomes of achieving CDC in patients continuing on FIL200 in the ongoing long-term extension (LTE) study SELECTIONLTE (NCT02914535). Methods This interim analysis included adult patients with UC who completed SELECTION and received ≤144 weeks of FIL200 in the LTE (up to data cut-off 24/02/22). CDC (biomarker remission, endoscopic improvement, IBDQ remission and partial Mayo Clinic Score [pMCS] remission achieved concurrently) was assessed at SELECTION week 58 (LTE baseline [BL]). Mean pMCS and IBDQ score, use of corticosteroids (CS) and incidence of TEAEs and serious TEAEs in the LTE were compared between SELECTION CDC achievers and non-achievers. A mixed model for repeated measures was fitted on pMCS and IBDQ score, with CDC achiever status, study visit and the interaction between CDC achiever status and study visit as fixed effects; p values were nominal. Results We analysed 148 patients (CDC achievers, n=41; CDC non-achievers, n=107). Mean pMCS was stable in CDC achievers (0.44, LTE BL; 0.50, LTE week 144) and decreased in CDC non-achievers (1.49, LTE BL; 0.77, LTE week 144; Figure). Mean IBDQ score was stable in CDC achievers (204.05, LTE BL; 197.21, LTE week 144) and increased in CDC non-achievers (181.55, LTE BL; 196.37, LTE week 144; Figure). There was a significant beneficial effect of achieving CDC on pMCS and IBDQ score overall (pMCS: fixed effect estimate: −0.5542, p=0.0025; IBDQ score: fixed effect estimate: 13.1585, p=0.0042). There was a significant interaction between achieving CDC and study visit for IBDQ score (p=0.0183), with the benefit of achieving CDC lessening by week 144. Generally, a lower proportion of CDC achievers used CS than non-achievers; 2.4–7.3% of CDC achievers used CS vs 1.9–15.9% of CDC non-achievers. Incidence of TEAEs and serious TEAEs were stable over time and similar between CDC achievers and non-achievers. Conclusion Follow-up for ~3 years showed high levels of long-term benefit with continued FIL200 treatment. Achieving comprehensive disease control at the end of the randomized trial with FIL200 was associated with long-term efficacy, improved HRQoL and low overall use of CS. This may demonstrate the value of filgotinib-induced achievement of CDC in UC disease course. The safety profile of FIL200 was consistent between CDC achievers and non-achievers, suggesting an acceptable long-term benefit–risk profile.

Abstract Background The primary objective of the VIVID-1 trial (NCT03926130) was to demonstrate efficacy and safety of mirikizumab (miri), a p19-directed anti-IL-23 antibody, compared to placebo (PBO) in patients (pts) with moderate-to-severe Crohn’s disease. Miri demonstrated statistically significant improvements in co-primary and all key secondary endpoints versus (vs) PBO1. Here we present the results of secondary endpoints on the comparisons of miri to ustekinumab (uste), a p40 directed anti-IL-12/IL-23 inhibitor from the Phase 3, randomised, double-blind, double-dummy, active- and PBO-controlled, treat-through (TT) study, VIVID-1 (NCT03926130). Methods Adult pts (N=1065) were randomised 6:3:2 to miri (N=579) 900mg intravenously (IV) every 4 weeks (Q4W) to W12, then 300mg subcutaneously (SC) Q4W to W52, uste (N=287) one ~6 mg/kg IV dose, then 90mg SC Q8W to W52 or PBO (N=199). At W12 PBO responders continued PBO to W52; PBO non-responders received the same blinded miri regimen as described above (IV then SC). Efficacy of miri vs uste was assessed by the proportion of pts achieving endoscopic response and by the proportion of pts achieving clinical remission by Crohn’s Disease Activity Index (CDAI) at W52 (both gated). Additional non-multiplicity-adjusted endpoints included endoscopic remission, corticosteroid-free clinical remission by CDAI, and the composite of CDAI clinical remission and endoscopic response at W52. (Figure 1 for definitions). Results Baseline characteristics were overall balanced across the three treatment groups (table 1). Pts treated with miri achieved all key major secondary endpoints (p<.000001) compared to PBO (Figure 1). Miri achieved non-inferiority to uste for clinical remission by CDAI (p=0.113117) (Figure 1C). Although superiority to uste in endoscopic response was not achieved (p=0.51) (Figure 1A), in biologic failed pts miri demonstrated a numerical trend towards greater response rates compared to uste for endoscopic response and clinical remission by CDAI (Figure 1 B & D). The overall safety profile was consistent with the known safety profile of miri. The proportion of treatment emergent adverse events (TEAE) were similar for miri (78.6%) and uste (77.3%); most common TEAEs were COVID-19, anaemia, arthralgia, headache, upper respiratory tract infection, nasopharyngitis and injection site reaction. Instances of serious adverse events were comparable for miri (10.3%) and uste (10.7%). Conclusion In this phase 3 TT design study, miri achieved non-inferiority to uste for clinical remission by CDAI. In biologic failed pts miri had a numerical trend towards greater response compared to uste in clinical and endoscopic endpoints, with an acceptable safety profile. 1Ferrante et al., submitted to ECCO 2024
