Galapagos to present data on rheumatoid arthritis at the upcoming European League Against Rheumatism (EULAR) congress

Mechelen, Belgium, 27 May 2021, 22:01 CET, – Galapagos NV (Euronext & Nasdaq: GLPG) today announced that 15 abstracts, including scientific updates, and data providing further understanding on the profile of filgotinib as a treatment for people with Rheumatoid Arthritis (RA), will be presented at the European League Against Rheumatism (EULAR) virtual congress 2021, 2-5 June.

New data analyses on the safety profile of filgotinib, an oral, once-daily, JAK1 preferential inhibitor for the treatment of moderately to severely active RA, are presented from seven trials from the development program for filgotinib (DARWIN 1 and 2 and FINCH 1, 2 and 3 and two long term extension studies DARWIN 3 and FINCH 4). Data will be shared on the incidence of infections and serious infections (OP0126) and herpes zoster virus (POS0092), as well as the effects of concomitant use of statins in filgotinib-treated patients with rheumatoid arthritis (POS0660) and the effect of filgotinib on the pharmacokinetics of rosuvastatin, atorvastatin, and pravastatin (AB0259).

Galapagos is also presenting scientific research investigating the hypothesis that differences in the selectivity of molecules in the JAK inhibitor class could result in a differential functional modulation of natural killer (NK) cells, which could be a component of the differences in clinical safety profiles of JAK inhibitors (POS0224).

In addition to the clinical data, Galapagos will present initial results from a European real-world survey investigating patient and physician attitudes to setting treatment target goals in RA, as a strategy for managing the disease (POS0305).

“At Galapagos, we are working to understand the different dimensions of treatment needs that people living with RA say are important, reflecting a deeper understanding of their complex lives and needs,” said Walid Abi-Saab, MD, Chief Medical Officer at Galapagos. “In our drive to deliver innovation and make a real difference where the patient need is greatest, we are excited to be sharing a range of data and insights that represent our ongoing work to understand what matters most to people living with RA and to deliver on the health outcomes most important to patients.”

The presentations at EULAR capture a broad range of research and commitment to the RA community, demonstrating the importance of patient and clinical insight and highlighting Galapagos’ position as a science-driven company led by research into patient unmet needs.

About rheumatoid arthritis
RA is a chronic inflammatory disease. In RA a person’s immune system attacks healthy cells, causing painful swelling in affected parts of the body, primarily in the joints.1 RA can cause tissue damage resulting in chronic pain, unsteadiness and physical disability.1 More than 2.3 million individuals are living with RA in Europe2 and women are 2 – 3 times more likely to develop RA.3 The onset of disease is typically between 30 and 50 years of age.4

About filgotinib
Filgotinib is approved and marketed as Jyseleca (200mg and 100mg tablets) in the European Union, Great Britain, and Japan for the treatment of adults with moderate to severe active rheumatoid arthritis (RA) who have responded inadequately or are intolerant to one or more disease modifying anti-rheumatic drugs (DMARDs). Filgotinib may be used as monotherapy or in combination with methotrexate (MTX). The European Summary of Product Characteristics for filgotinib, which includes contraindications and special warnings and precautions, is available at The interview form from the Japanese Ministry of Health, Labour and Welfare is available at The Great Britain Summary of Product Characteristics is available at Applications have been submitted to the European Medicines Agency (EMA), the UK’s Medicines and Healthcare products Regulatory Agency (MHRA), and Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) for the treatment of adults with moderately to severely active ulcerative colitis who have had an inadequate response with, lost response to, or were intolerant to either conventional therapy or a biologic agent and are currently under review. Filgotinib is not approved in any other countries.

About the filgotinib collaboration
Gilead and Galapagos NV are collaborative partners in the global development and commercialization of filgotinib. Galapagos will be responsible for the commercialization of filgotinib in Europe (transition anticipated to be completed by end of 2021), while Gilead will remain responsible for filgotinib outside of Europe, including in Japan, where filgotinib is co-marketed with Eisai. Filgotinib in UC has been filed in Europe and a global Phase 3 program is ongoing in Crohn’s Disease. More information about clinical trials can be accessed at
