In the approach to treatment of patients with rheumatoid arthritis (RA), methotrexate monotherapy is often followed by addition of a biologic disease modifying anti-rheumatic drugs (bDMARDs) for best disease outcomes. Combination DMARDs therapy with methotrexate, hydroxychloroquine, and sulfasalazine (triple therapy) has been proposed as an alternative to biologic therapy. Combination methotrexate and leflunomide is not as frequently addressed in the literature, perhaps due in part to concerns about hepatotoxicity. Bredemeier et al address safety concerns regarding combination methotrexate and leflunomide in the treatment of patients with RA. In this multicenter Brazilian registry study, they compared adverse events (including infection) among patients receiving bDMARDs or JAK inhibitors. Patients treated with combination methotrexate and leflunomide had comparable rates of adverse effects as patients treated with either medication alone; infectious and serious adverse events were fewer compared to patients treated with bDMARDs or JAK inhibitors. Given this reassuring information, further study of the efficacy and durability of combination methotrexate and leflunomide therapy would be helpful to firmly establish its place in treatment of RA, especially among newer biologic choices.
Tofacitinib and tocilizumab, for example, have been under investigation for safety and efficacy, alone and in combination with conventional synthetic DMARDs (csDMARDs). Prior studies have suggested that tofacitinib is more effective in bDMARD-naïve patients than patients who have had inadequate efficacy with one or more bDMARDs. In this multicenter Japanese cohort study, Mori et al examine RA outcomes in new users of tofacitinib and tocilizumab. Clinical disease activity index (CDAI) responses and remission rates were significantly better among bDMARD-naïve patients receiving tofacitinib compared to those receiving tocilizumab; interestingly, this difference was not seen in patients who had previously received bDMARDs. Interpretation of these results is somewhat hampered by the use of the lower every-other-week tocilizimab injection dose, but they still raise the question as to whether timing and sequence of biologics can affect future response to therapy.
The role of conventional DMARDs has also been questioned in the converse role: tapering of therapy. Lillegraven et al compare tapering of csDMARDs to continuing therapy in this randomized multicenter Norwegian study. The possibility of biologic tapering in RA has previously been addressed with some evidence of success in the form of reduced frequency of administration. Unfortunately, despite being in stable remission, patients assigned to reduce csDMARDs to half-dose had more flares than those continuing therapy, suggesting that reducing csDMARDs to half-dose in RA patients in remission may not be easily accomplished. Whether this changes in patients with prolonged or “deep” remission is as yet unknown.
Finally, with all of these options for tailored therapy, how does our treatment of early RA fare? Combe et al report the 10-year outcomes of a French early RA cohort (ESPOIR), including patients with RA for <6 months recruited from 2003-2005. 521 patients were followed; at year 10, half were in DAS28 remission, and 14% in drug-free remission. Compared to outcomes from an earlier community- based study, patients in the ESPOIR cohort have better outcomes, possibly due to more aggressive treatment for RA, use of bDMARDs, or perhaps even earlier identification of patients for treatment. Due to the sizeable proportion of patients in drug-free remission, the impact of stringency of entry criteria should be considered, and a comparison to a later cohort with patients identified using 2019 ACR/EULAR criteria would be of great interest.
