Key clinical point: Withdrawal of methotrexate slightly worsened disease activity without affecting remission rates in patients with rheumatoid arthritis (RA) at target who were treated with the combination of biologic disease-modifying antirheumatic drugs (bDMARD)/targeted synthetic DMARD (tsDMARD) and methotrexate.
Major finding: Withdrawing methotrexate vs maintaining combination therapy increased the disease activity score of 28-joints by 0.20 (95% CI 0.09-0.32) and decreased the proportion of patients achieving low disease activity (risk ratio [RR] 0.88; 95% CI 0.80-0.97); however, the remission rates remained unaffected (RR 0.90; 95% CI 0.81-1.01).
Study details: Findings are from a systematic review and meta-analysis of six randomized controlled trials including 1430 patients with RA at target who were treated with bDMARD or tsDMARD+methotrexate combination therapy, of which 734 withdrew and 696 continued methotrexate.
