This session presents the best submitted clinical abstracts as determined by their specific council sections…

BACKGROUND: After successful induction, a subset of patients with Crohn’s disease (CD) experience a secondary loss of response (LoR) to ustekinumab (UST) maintenance therapy. Dose intensification may assist in regaining response…

BACKGROUND AND AIMS: A treat-to-target (TTT) strategy of striving for symptomatic and endoscopic remission is recommended for the management of inflammatory bowel diseases (IBD). Yet, real-world uptake of TTT strategies has been modest…

BACKGROUND: Biological treatment in inflammatory bowel disease (IBD) patients is currently hampered by high non-response rates. To enhance personalized medicine and predict response to biological therapeutics such as vedolizumab, the working mechanism should be elucidated…

Switching from originator to biosimilar infliximab (IFX) is effective and safe. However, data on multiple switching are scarce. The Edinburgh IBD unit has undertaken three switch programmes: (1) Remicade to CT-P13 (2016), (2) CT-P13 to SB2 (2020), and (3) SB2 to CT-P13 (2021)…

BACKGROUND: Gut dysbiosis is associated with persistent multi-system symptoms following SARS-CoV-2 infection, or post-acute COVID-19 syndrome (PACS). We performed a randomised controlled trial to assess the effects of gut microbiome modulation on alleviation of PACS symptoms…

The Phase 3 QUASAR Maintenance Study (NCT04033445) is a randomized-withdrawal, double-blind, placebo(PBO)-controlled, study that evaluated the efficacy and safety of maintenance treatment with subcutaneous (SC) guselkumab (GUS), an IL-23p19 subunit antagonist, in patients (pts) with moderately to s…

Background: Although the precise role of eosinophils in IBD is debated, elevated eosinophils may influence response to therapy and clinical outcomes1. Thus, therapeutic agents which affect both neutrophil and eosinophil recruitment may provide more robust clinical improvement in patients with UC…

BACKGROUND: Disease clearance in ulcerative colitis (UC) is defined as concurrent achievement of clinical, endoscopic, and histologic remission…

BACKGROUND: VTX002 is a novel oral selective sphingosine-1-phosphate-1 (S1P1) receptor modulator in development for the treatment of ulcerative colitis (UC)…

Obefazimod is an investigational, oral, once-daily, small molecule which enhances expression of microRNA-124 and is currently in phase 3 clinical trials for the treatment of patients with moderately to severely active ulcerative colitis (UC) [1]…

Infliximab (IFX) demonstrated its effectiveness in perianal CD (pCD) and represents the first-line medical treatment. A subcutaneous (SC) formulation has recently been developed, however so far it has not been specifically investigated in pCD…

Prospective data after switch from intravenous infliximab (IV-IFX) to subcutaneous (SC-IFX) in Inflammatory Bowel Disease (IBD) is needed. The aim of this prospective multicenter cohort was to describe SC-IFX persistence, efficacy and tolerance after switch from IV-IFX…
