Key clinical point: Blanket withdrawal of tofacitinib may not be suitable for all patients with rheumatoid arthritis (RA) who have achieved clinical remission as more than half relapsed after tofacitinib discontinuation. However, the majority regained remission after tofacitinib resumption.
Major finding: At week 104, the tofacitinib vs methotrexate discontinuation group had a numerically lower Clinical Disease Activity Index-based sustained remission rate (29.2% vs 50.0%) and higher relapse rate (58.3% vs 35.0%). However, 71.4% vs 28.6% of patients regained remission on tofacitinib vs methotrexate resumption.
Study details: This prospective randomized controlled trial included 113 patients with RA and an inadequate response to methotrexate with or without biologic disease-modifying antirheumatic drugs who received 52 weeks of tofacitinib plus methotrexate treatment and thereafter, were randomly assigned to discontinue tofacitinib or methotrexate if experiencing clinical remission.
