About this study

Despite their efficacy in the treatment of Rheumatoid Arthritis and their partial advantage over traditional bDMARDs ( biological Disease Modifying antirheumatic drugs), JAK inhibitors (JAKi or tsDMARDs) have not gained preference over Tumor Necrosis Factor inhibitors (TNFi) in guidelines or clinical practice. The biggest influence on recent guidelines has been the "Treat To Target" principle (T2T), in which Shared Decision Making (SDM) plays a key part. Patient preference has proven to be a large barrier in treatment adjustments (14- 37%) while patients showed better adherence and higher treatment satisfaction when engaged in Shared Decision Making. From survey studies it is suggested that patient preference and satisfaction will be in favour of oral JAK inhibitors over parenteral biologics.The investigators want to establish the treatment preference of patients with active RA and compare the treatment satisfaction of patients who are given the opportunity to choose between the JAKi filgotinib and TNFi, to the treatment satisfaction of patients who are randomized to the same treatment options. In addition to higher treatment satisfaction and better adherence, the investigators expect to find an improvement in DAS28-, HAQ-, SQUASH- and WPAI-scores and also an improved activity and work productivity.
