- Continuing filgotinib 200mg among induction non-responders at week 10 resulted in clinical benefits for ulcerative colitis (UC) patients in the long-term extension study (LTE)
- Treatment with filgotinib 200mg resulted in clinically meaningful improvements in health-related quality of life (HRQoL) measures by week 58 among patients with UC
Mechelen, Belgium; 4 October 2021, 22.01 CET; Galapagos NV (Euronext & NASDAQ: GLPG) today announced results of two post-hoc analyses from the SELECTION and SELECTION LTE studies, which are part of the investigational clinical program for filgotinib, for the treatment of patients with moderately to severely active UC. These analyses showed clinical benefits of continued dosing with filgotinib 200mg, an oral once-daily JAK1 preferential inhibitor, in patients who did not respond at week 10. Separately, HRQoL benefits of filgotinib 200mg treatment versus placebo, in patients with UC were shown. These data will be presented at the UEGW virtual 2021 congress (3 – 5 October).
In SELECTION, patients who did not respond to induction therapy at week 10 could receive open-label filgotinib in the LTE. In a post-hoc analysis, it was shown that continuing filgotinib 200mg among those non-responders resulted in 65.7% biologic-naïve and 62.2% biologic-experienced patients achieving partial Mayo Clinic Score (pMCS) response by Week 12, with 17.1% biologic-naïve and 16.7% biologic-experienced patients in pMCS remission (Presentation MP082).1
A post-hoc analysis of HRQoL data from the SELECTION study shows that patients treated with filgotinib 200mg achieved clinically meaningful improvements in their quality of life, versus placebo. These included Inflammatory Bowel Disease Questionnaire remission and measurements of productivity, physical, and mental components, assessed by 36-item Short Form Survey (SF-36), EuroQol 5-dimension (EQ-5D) visual analogue scale and Work Productivity and Activity Impairment questionnaire (Poster PO457).2
Dr Walid Abi-Saab, Chief Medical officer, at Galapagos said, “The SELECTION study has provided us with a wealth of data on the efficacy and safety profile of filgotinib that, if approved can potentially inform clinical treatment approaches. This includes findings on the benefits of prolonged dosing with filgotinib 200mg among induction non-responders and the achievement of treatment goals beyond clinical symptoms of UC. We know that patients with UC are impacted by this disease physically, socially and psychologically, which is why inclusion of health-related quality of life measures in our clinical trials is so important to build a holistic understanding of the management of the disease.”
These data were in two of thirteen abstracts from the company relating to filgotinib in the treatment of patients with UC. The use of filgotinib for the treatment of UC is investigational and is not approved anywhere globally.

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 people3 are affected by IBD, which includes UC and Crohn’s Disease (CD). UC is a chronic inflammatory condition of the gastrointestinal (GI) tract. The disease course of UC is often a state of flare ups and ensuing periods of 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 Phase 3 Trial
The SELECTION Phase 3 trial is a multi-center, randomized, double-blind, placebo-controlled trial to assess the safety and efficacy of the preferential JAK1 inhibitor filgotinib in adult patients with moderately to severely active UC. The SELECTION trial 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 subscore of 0, and ≥ 1-point decrease in stool frequency from baseline to achieve a subscore 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 trial 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 trial had a MCS score of 9 or higher at baseline, and 43% of biologic experienced patients had insufficient response to a TNF antagonist and vedoluzimab as well.
About HRQoL and IBDQ
Health-related quality of life (HRQoL) is a concept that measures physical, emotional, mental, and social impact of the disease on patients’ lives. The instruments used to measure HRQoL were a 36-item Short Form Survey (SF-36), EuroQol 5-dimension visual analogue scale (EQ-5D-VAS) and Work, Productivity and Activity Impairment (WPAI) questionnaire, and Inflammatory Bowel Disease Questionnaire (IBDQ).
The IBDQ is a questionnaire for health-related quality of life assessment in patients with inflammatory bowel diseases: ulcerative colitis and Crohn’s disease. It consists of 32 questions divided into four groups: bowel symptoms (10 items), systemic symptoms (5 items), emotional function (12 items) and social function (5 items). Every question has graded responses from 1 to 7, and thus the total score can range from 32 to 224 with higher scores representing better health-related quality of life. IBDQ remission was defined by an IBQ total score ≥170 points. The IBDQ is a validated assessment tool that reflects important changes in the quality of life of patients with IBD (adapted from Pallis et al, Inflamm Bowel Dis, Volume 10, Number 3, May 2004).
SF-36 is a generic health-assessment questionnaire that is utilized in clinical trials to study the impact of chronic disease on health-related quality of life.
EQ-5D is a general, non–disease-specific health-related quality-of-life questionnaire.
WPAI is a tool used to measure the impact of a disease on work and on daily activities.
