Key clinical point: Continuation of conventional synthetic disease-modifying antirheumatic drugs (csDMARD) was not superior to withdrawal in patients with rheumatoid arthritis (RA) in sustained remission with half-dose csDMARD, suggesting withdrawal of half-dose csDMARD is feasible in some patients.
Major finding: Although discontinuing vs continuing half-dose csDMARD led to a numerically higher risk for flares within 12 months (risk difference 21.5%; 95% CI −3.4% to 49.7%), more patients discontinuing vs continuing half-dose csDMARD showed no radiographic joint damage progression (risk difference 13.9%; 95% CI −10.6% to 38.3%) and regained Disease Activity Score-based remission (80.0% [95% CI 44.4%-97.5%] vs 66.7% [95% CI 9.5%-99.2%]) at the first visit after flare.
Study details: This open-label trial, a part of the ARCTIC REWIND project, included 56 patients with RA who were in sustained remission for ≥12 months with half-dose csDMARD and were randomly assigned to discontinue or continue half-dose csDMARD.
