Rheumatoid Arthritis Clinical Trial

Official title: Better After CHoosing. Randomly Allocated or Patient Preference Based Treatment With Filgotinib or TNFi in Patients With Active Rheumatoid Arthritis (BACH)

Status Recruiting

Clinical Trial Summary

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.

Clinical Trial Description

Rationale: Despite their efficacy in the treatment of Rheumatoid Arthritis and their partial advantage over traditional bDMARDs, 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.

Objective:

• To evaluate the actual preference of patients when they decide themselves which mode of action they want to use for treatment of rheumatoid arthritis.

• To evaluate differences in treatment satisfaction between patients who can choose their therapy and those patients that are randomized for the same treatment options.

• To evaluate if adherence to therapy is increased when patients decide their own therapy.

• To evaluate the difference in improvement of disease activity by the Disease Activity Score (DAS28) and physical activity as measured by SQUASH questionnaire and fitness trackers.

Study design: This study is a multicenter, randomized, 24-week, open label trial

Study population and intervention:

Early, bDMARD naive RA patients, of whom a group of 50 patients will be given the opportunity to choose between either TNFi (etanercept 50 mg SC once a week or adalimumab 40 mg SC once every two weeks) or filgotinib, an oral JAKi, 200 mg once a day while another group of 50 patients will be randomized to the same treatment arms.

Main study parameters/endpoints: The two primary endpoints consist of:

• The proportion of subjects in the first subgroup choosing filgotinib therapy at baseline

• Treatment satisfaction of both subgroups at week 24 at a 5-point Likert scale for current medical treatment.

Burden and risks associated with participation, benefit and group relatedness: All medication is prescribed at the indicated dosages used in clinical care, according to international guidelines. Study burden and risks are similar to daily clinical care: In addition to daily clinical care one half of the participants has to make the treatment choice and all participants will fill in questionnaires, which will take about 15 minutes to complete. ;
