The purpose of this study is to assess the effect of disease-modifying anti-rheumatic drugs (DMARDs) dose reduction in patients with rheumatoid arthritis (RA). Remission is the treatment target in RA, but knowledge about the best way to treat RA patients who achieve sustained remission is limited. DMARDs have potential serious adverse events, and biologic DMARDs are costly to the society. The objectives for ARCTIC REWIND are to assess the effect of tapering and withdrawal of DMARDs on disease activity in RA patients in sustained remission, to study predictors for successful tapering and withdrawal of DMARDs in this patient group, and to study cost-effectiveness of different treatment options in RA remission. ARCTIC REWIND is a randomized, open, controlled, parallel-group, multicenter, phase IV, non-inferiority strategy study. Patients with less than five years of disease duration and stable remission for at least 12 months are randomized to either continued stable treatment or tapering and withdrawal of DMARDs, including tumor necrosis factor (TNF) inhibitors and synthetic DMARDs. Patients are assessed by clinical examination, patient reported outcome measures, ultrasonography, MRI and X-ray, and monitored for adverse events. The primary endpoint of the study is the proportion of patients who are non-failures (have not experienced a flare) at 12 months. Secondary endpoints include composite disease activity scores and remission criteria, joint damage and inflammation assessed by various imaging modalities, work participation, health care resource use and health related quality of life.

Primary | Proportion of patients who are non-failures (have not experienced a flare) | Flare is defined as composite measure: (1) An increase in disease activity score (DAS) to >1.6 AND (2) a change in DAS of at least 0.6 AND (3) > 1 swollen joint. If a patient does not fulfill this formal definition, but experiences a clinically significant flare according to the investigator and patient, this is treated as a flare. | 12 months | |
Secondary | Disease Activity Score (DAS) | The DAS is a composite score that includes the Ritchie articular index (RAI), the 44- swollen joint counts (SJC-44), the Erythrocyte Sedimentation Rate (ESR) and a general health (GH) assessment on a Visual Analogue Scale (VAS). The DAS is calculated as follows: DAS = 0.54*sqrt(RAI) + 0.065*(SJC-44) + 0.33*Ln(ESR) + 0.0072*GH |
