Réponse soutenue après Arrêt du Méthotrexate ches des Patients Atteints de Polyarthrite Rhumatoïde Traités avec du Tocilizumab en Sous-Cutané Tocilizumab
The COMP-ACT study showed patients achieving low disease activity (LDA) with tocilizumab (TCZ) plus methotrexate (MTX) can discontinue MTX, while maintaining disease control for up to 16 weeks.
Previous studies have shown TCZ to be efficacious as a monotherapy or in combination with MTX in patients with RA1,2. Patients frequently discontinue taking DMARDs, such as MTX, due to intolerance or adverse events.
COMP-ACT is a randomised, double-blind, 52-week study evaluating the sustained efficacy of subcutaneous TCZ monotherapy versus combination therapy, following combination therapy for 24 weeks.
The mean change in the DAS28 from discontinuation to Wk40 was similar for both treatment groups. Additionally, the proportion of patients who maintained LDA or remission at Wks40 and 52 were similar between treatment arms.
Safety outcomes in this study were comparable between the treatment groups. There was a slightly higher incidence of adverse events (AEs) in patients randomized to combination therapy
The authors concluded that, in patients achieving LDA with MTX and TCZ combination therapy, MTX can be discontinued without diminishing disease control for up to 16 weeks.
