Galapagos provides further insights into the treatment of ulcerative colitis at the upcoming United European Gastroenterology (UEG) Week 2022 congress

  • Five presentations demonstrate Galapagos’ commitment to inflammation and the ulcerative colitis (UC) community
  • New analyses will be presented from the SELECTION data set on prediction of response and remission, histology data and trajectory model
  • Presentation on safety data of filgotinib in enriched risk population in rheumatoid arthritis  

Mechelen, Belgium; 6 October 2022, 22.01 CET, Galapagos NV (Euronext & NASDAQ: GLPG) will present data at the United European Gastroenterology (UEG) Week 2022, taking place from 8-11 October 2022. Several Galapagos driven presentations will be showcased, including new post hoc analyses of the SELECTION study, which investigated the safety and efficacy of Jyseleca® (filgotinib), an oral, once-daily, JAK1 preferential inhibitor, in patients with moderately to severely active UC.

Dr Walid Abi-Saab, Chief Medical officer of Galapagos said, “We continue to analyze data from the different studies of filgotinib in patients with UC to inform and empower healthcare professionals to make the most appropriate choices for patients. We are committed to making a real difference to patients by finding ways to better treat this debilitating condition and are excited to share these data and insights at the UEG Week.”

In addition to clinical data presentations, Galapagos is also hosting a hybrid symposium: JAK to the future – a patient centric choice in UC on Monday 10 October 2022, which will feature experts’ perspectives on taking a patient-centric, comprehensive approach to disease control as the best approach to address current unmet needs in UC management and on how the JAK class can help HCPs navigate the current and future treatment landscape.

About ulcerative colitis 
Ulcerative colitis (UC) is a debilitating inflammatory bowel disease (IBD) that occurs as a result of an abnormal immune system response. Across Europe an estimated 2.5 – 3 million people1 are affected by IBD, which includes UC and Crohn’s disease (CD). UC is a chronic inflammatory condition characterized by periods of flare ups followed by remission. In addition to the physical impact from flare ups, there is also a psychological impact associated with UC. It causes significant impairments on quality of life and a poor prognosis is often seen in patients with symptoms of moderate to severe UC at diagnosis.

About the SELECTION study
The SELECTION Phase 3 study is a multi-center, randomized, double-blind, placebo-controlled study to assess the safety and efficacy of the preferential JAK1 inhibitor filgotinib in adult patients with moderately to severely active UC. The SELECTION study (NCT02914535) comprises two induction trials and a maintenance trial. The Induction Study A enrolled biologic-naïve patients, and the Induction Study B enrolled biologic-experienced patients.

The primary objectives of SELECTION were to evaluate the efficacy of filgotinib compared with placebo in establishing clinical remission as determined by the Mayo endoscopic subscore of 0 or 1, rectal bleeding sub-score of 0, and ≥ 1-point decrease in stool frequency from baseline to achieve a sub-score of 0 or 1 at Week 10 in the induction studies and Week 58 in the maintenance study. Eligible patients who were enrolled in the SELECTION study were enrolled in the ongoing SELECTION long-term extension trial to evaluate the long-term safety of filgotinib in patients with UC. A majority of patients included in the SELECTION study (n=1348) had a Mayo Clinic Score (MCS) of 9 or higher at baseline, and 43% of biologic experienced patients (n=297/689) had insufficient response to a TNF antagonist and vedoluzimab as well. (Feagan et al., Lancet 2021; 397: 2372–84)

About filgotinib
Filgotinib is marketed as Jyseleca (200mg and 100mg tablets) in the European Union (incl. Norway), Great Britain, and Japan for the treatment of adults with moderately to severely active rheumatoid arthritis (RA) who have responded inadequately or are intolerant to one or more disease modifying anti-rheumatic drugs (DMARDs). Filgotinib is also marketed as Jyseleca (200mg tablets) in the European Union (incl. Norway), Great Britain, and Japan for the treatment of adult patients with moderately to severely active ulcerative colitis (UC) who have had an inadequate response with, lost response to, or were intolerant to either conventional therapy or a biologic agent. A global Phase 3 program with filgotinib is ongoing in Crohn’s Disease. More information about clinical trials can be accessed at

The European Summary of Product Characteristics for filgotinib, which includes contraindications and special warnings and precautions, is available at The Great Britain Summary of Product Characteristics for filgotinib can be found at and the Northern Ireland Summary of Product Characteristics for filgotinib can be found at, respectively. The interview form from the Japanese Ministry of Health, Labour and Welfare is available at

Except for filgotinib’s approval as Jyseleca for the treatment of moderately to severely RA and UC by the relevant regulatory authorities in the European Union, Great Britain, and Japan, our drug candidates are investigational; their efficacy and safety have not been fully evaluated by any regulatory authority.
