Galapagos demonstrates commitment to immunology with new data in rheumatoid arthritis at EULAR 2023

  • 9 poster presentations and 3 abstracts publications reinforce Galapagos’ commitment to immunology and the rheumatoid arthritis (RA) patient and healthcare professional community
  • New analyses will be presented from long-term extension studies providing insights into filgotinib’s effectiveness and safety
  • Interim baseline characteristics, effectiveness and safety outcomes will be published online from the real-world FILOSOPHY study in RA patients

Mechelen, Belgium; 22 May 2023, 22:01 CET; Galapagos NV (Euronext & NASDAQ: GLPG) will present a broad range of abstracts, including analysis from randomized controlled trials (RCTs) and real-world evidence (RWE) studies at the European League Against Rheumatism (EULAR) annual congress taking place from 31 May to 3 June 2023 in Milan.

“We are focused on advancing treatment options for chronic, debilitating immune-mediated diseases such as RA and are excited to present further analyses on filgotinib’s efficacy and safety profile at this year’s EULAR congress,” said Daniele D’Ambrosio, MD, PhD, Therapeutic Area Head, Immunology, at Galapagos. “Our presence at EULAR underscores our firm commitment to develop transformational therapies to improve the lives of patients around the world.”

A number of abstracts will present trial data analyses on filgotinib, a once-daily oral preferential JAK-1 inhibitor, for the treatment of moderate to severe active RA. Key presentations include long-term efficacy and integrated safety data, post hoc analysis identifying distinct trajectories of treatment responses in patients with RA receiving filgotinib, the long-term clinical profile of filgotinib in patients with RA by cardiovascular (CV) risk factors, and the added value of filgotinib on pain relief in patients with RA achieving remission in the Phase 3 FINCH 1, 2 and 3 studies (NCT02889796, NCT02873936 and NCT02886728). Additionally, interim results from 500 patients on baseline characteristics as well as effectiveness and safety outcomes from the FILOSOPHY real-world evidence study (NCT04871919), which has now enrolled over 1000 patients in RA, will be published online.

Furthermore, Galapagos is hosting a symposium: “JAK to reality: seeking clarity in RA”, which will focus on key considerations when selecting treatments for RA patients, efficacy and safety of JAK inhibitors, and the practical use of JAK inhibitors in the treatment of RA patients. An interactive meet-the-expert session: “Burning questions: the practical use of JAK inhibitors in RA”, will feature an expert faculty sharing insights and answers to audience questions on recent developments in the RA treatment landscape and the potential implications for clinical practice. In addition to exhibiting an interactive booth that attendees can explore at the congress, Galapagos is also hosting a media roundtable discussion featuring experts, including a patient representative, discussing the real-life impact of RA and exploring solutions to overcome and manage the burden of the disease.

About rheumatoid arthritis (RA)
Rheumatoid arthritis (RA) is an autoimmune inflammatory disease that primarily causes pain, stiffness and swelling in the joints. RA often follows a painful, progressively debilitating course, depriving patients of the ability to continue their daily lives and leading to physical disability. Despite current treatments, RA continues to pose a substantial burden to people living with the disease, comprised of the daily health issues directly related to their RA, such as pain, and the complications of managing comorbid conditions.1,2,3
