Abstract Background There is an unmet need for ulcerative colitis (UC) treatments that show improved effectiveness while maintaining safety profiles comparable with existing advanced therapies. Dual targeted therapy (DTT) has been proposed as a strategy to combine benefits of different advanced therapies to improve outcomes. The ExiGem study (NCT06095128) aims to assess the efficacy and safety of combined therapy with vedolizumab (VDZ) and tofacitinib (TOF) in adults with UC. We report results for the induction phase from the first 24 patients. Methods ExiGem is an ongoing phase 4, single-arm, multicentre study including adults with moderately to severely active UC (complete Mayo [cMayo] score of 6–12 with a rectal bleeding subscore ≥ 1 and centrally read endoscopic subscore ≥ 2). Eligible patients have previously had an inadequate response, loss of response, or intolerance to 1 or 2 anti-tumour necrosis factor α treatments. Patients receive induction therapy with intravenous (IV) VDZ 300 mg at weeks 0, 2, and 6 plus twice-daily oral TOF 10 mg for 8 weeks and then VDZ 300 mg IV monotherapy as maintenance from week 14. The primary endpoint is the proportion of patients in clinical remission by cMayo score at week 8. Secondary endpoints include clinical response and clinical remission by modified Mayo (mMayo) score at week 8. Changes in faecal calprotectin (FCP) levels and endoscopic improvement were evaluated. Efficacy data were analysed using non-responder imputation. For the final analysis a pre-specified Bayesian approach will be used. The safety profile of DTT was evaluated. Results Patient baseline characteristics are shown in Table 1. At week 8, 12/24 patients (50%) and 14/24 patients (58%) had clinical remission assessed by cMayo and mMayo scores, respectively; these rates were higher than pre-specified benchmark rates (Figure 1). Clinical response was observed in 21/24 patients (88%). At week 8, 14/24 patients (58%) showed endoscopic improvement, and 12/21 patients (57%) had normalization of FCP levels (< 250 µg/g). Treatment-emergent adverse events (TEAEs) were experienced by 10 patients (42%), and 1 serious TEAE was reported (suspected viral infection). One severe adverse event (AE; cough) and 2 moderate AEs (herpes zoster, drug intolerance) were considered related to TOF. No moderate or severe AEs were considered related to VDZ. One patient withdrew from the study before week 8 owing to intolerance to TOF. Conclusion Initial data suggest that induction with a combination of VDZ and TOF can produce improved rates of response and remission in patients with UC with a comparable safety profile to existing advanced monotherapies. Further data, including outcomes of VDZ maintenance as monotherapy, are pending.

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.

Abstract Background Risankizumab (RZB), a high-affinity humanised IgG1 monoclonal antibody targeting interleukin-23 p19, has demonstrated sustained efficacy, with a consistent safety profile supporting long-term use for patients (pts) with ulcerative colitis (UC).1-3 This interim analysis reports efficacy and safety through open-label extension (OLE) week (wks) 96 (3 years [yrs] of total maintenance) from the COMMAND OLE. Methods The OLE enrolled RZB-treated pts who completed the 52-wk maintenance substudies and/or responded to 12/24-wk induction therapy.1 All pts received subcutaneous RZB 180 mg (RZB180) starting at OLE wk 0, except those who received prior OLE RZB rescue therapy (1 RZB 1200 mg intravenous dose then RZB 360 mg [RZB360] every 8 wk) and continued RZB360 for 96 wks. Efficacy endpoints (clinical remission [CR] per Adapted Mayo Score [AMS], CR per Partial AMS [PAMS], corticosteroid-free CR per PAMS, clinical response per AMS, clinical response per PAMS, endoscopic improvement, and endoscopic remission) were assessed at OLE wks 0 and 96 and reported as observed (AO) prior to OLE RZB rescue therapy and nonresponder imputation (NRI), among the overall population and by inadequate response to advanced therapy (AT-IR vs non-AT-IR; data cutoff: 25Aug2025). The safety analysis included pts who received at least 1 dose of OLE RZB, with data presented as events/100 pt-yrs. Results At OLE wk 0, approximately 90% pts (N = 1003) completed the study visit; some differences were observed in the clinical characteristics of RZB180 and RZB360-treated pts, including mean AMS (2.0, 3.4); a numerically higher proportion of RZB360-pts were AT-IR (63.1%, 76.8%), and had an endoscopic score of ≥ 3 (12.1%, 31.1%). A lower proportion of RZB360-treated pts achieved CR per AMS (54.8%, 25.2%) at OLE wk 0, while a higher proportion of RZB360-treated pts received OLE rescue therapy (RZB180, 22.1%; RZB360, 34.5%). Efficacy rates remained stable at OLE wks 0 and 96 for CR per AMS; similar results were observed within each subgroup, AT-IR and non-AT-IR (Table 1). Numerically lower efficacy rates were observed in the AT-IR vs non-AT-IR pts at wk 96; efficacy was sustained through OLE wk 96 for all endpoints (AO, NRI; Table 1). Similar rates were observed for any adverse event (AE), severe AE, and serious AE in RZB180 and RZB360-treated pts. No new safety risks were identified in either treatment group (Table 2). Conclusion In the ongoing COMMAND OLE, sustained clinical and endoscopic benefit was observed in pts receiving up to 3 yrs of long-term RZB maintenance therapy, with numerically lower efficacy rates observed for AT-IR vs non-AT-IR vs pts. The long-term safety of RZB remains consistent with a favorable benefit-risk profile, supporting its long-term use in UC. References: 1.Louis E et al. JAMA. 2024;332:881-97. 2.Atreya R et al.
