Abstract

Introduction/objectives: Evidence regarding the effectiveness of step-down strategies for patients with well-controlled early rheumatoid arthritis (RA) on a combination of methotrexate (MTX) and leflunomide (LEF) is currently lacking.

Method: The Care in early RA (CareRA) trial is a 2-year randomized pragmatic trial comparing different remission induction strategies in treatment-naïve patients with early RA. For this study, we included participants who achieved low disease activity (LDA) (DAS28-CRP ≤ 3.2) between 40 to 52 weeks after starting a combination of MTX, LEF, and a prednisone bridging scheme followed by a treat-to-target approach. Patients were re-randomized to a maintenance monotherapy of either MTX 15 mg weekly or LEF 20 mg daily. Remission rates (DAS28-CRP < 2.6) at week 65 counted from re-randomization, as well as drug retention rates and safety during the 65 weeks of follow-up, were compared.

Results: Remission rates at week 65 after re-randomization were numerically higher in patients assigned to MTX (29/32; 90.6%) compared with patients on LEF (20/27; 74.1%) (p = 0.091). Of patients assigned to MTX, 60% (19/32) maintained LDA while continuing their assigned monotherapy until week 65 after re-randomization versus 44% (12/27) in the LEF group (p = 0.25). Patients re-randomized to MTX were more frequently in LDA measured by Clinical Disease Activity Index (32/32; 100%) compared with patients on LEF (23/27; 85.2%) (p = 0.024) 65 weeks after re-randomization. According to survival analyses, the probability of maintaining MTX monotherapy was higher (81%) than maintaining LEF monotherapy (55%) for 65 weeks (p = 0.025) after re-randomization. Safety analysis after re-randomization showed a good safety profile in both groups.

Conclusion: MTX monotherapy seems not significantly more efficacious as maintenance treatment compared with LEF monotherapy but has a better retention rate and is well tolerated in early RA patients in LDA after combination therapy with both.

Trial registration: Clinical trials NCT01172639 Key points • Methotrexate should be preferred over leflunomide as maintenance therapy after an initial intensive combination of these two drugs. • Methotrexate shows a better retention rate to leflunomide as maintenance therapy in this context.
