OBJECTIVES: To inform the 2019 update of the European League against Rheumatism (EULAR) recommendations for the management of rheumatoid arthritis (RA).
METHODS: A systematic literature research (SLR) to investigate the efficacy of any disease-modifying antirheumatic drug (DMARD) (conventional synthetic (cs)DMARD, biological (b) and biosimilar DMARD, targeted synthetic (ts)DMARD) or glucocorticoid (GC) therapy in patients with RA was done by searching MEDLINE, Embase and the Cochrane Library for articles published between 2016 and 8 March 2019.
RESULTS: 234 abstracts were selected for detailed assessment, with 136 finally included. They comprised the efficacy of bDMARDs versus placebo or other bDMARDs, efficacy of Janus kinase (JAK) inhibitors (JAKi) across different patient populations and head-to-head of different bDMARDs versus JAKi or other bDMARDs. Switching of bDMARDs to other bDMARDs or tsDMARDs, strategic trials and tapering studies of bDMARDs, csDMARDs and JAKi were assessed. The drugs evaluated included abatacept, adalimumab, ABT-122, baricitinib, certolizumab pegol, SBI-087, CNTO6785, decernotinib, etanercept, filgotinib, golimumab, GCs, GS-9876, guselkumab, hydroxychloroquine, infliximab, leflunomide, mavrilimumab, methotrexate, olokizumab, otilimab, peficitinib, rituximab, sarilumab, salazopyrine, secukinumab, sirukumab, tacrolimus, tocilizumab, tofacitinib, tregalizumab, upadacitinib, ustekinumab and vobarilizumab. The efficacy of many bDMARDs and tsDMARDs was shown. Switching to another tumour necrosis factor inhibitor (TNFi) or non-TNFi bDMARDs after TNFi treatment failure is efficacious. Tapering of DMARDs is possible in patients achieving long-standing stringent clinical remission; in patients with residual disease activity (including patients in LDA) the risk of flares is increased during the tapering. Biosimilars are non-inferior to their reference products.
CONCLUSION: This SLR informed the task force regarding the evidence base of various therapeutic regimen for the development of the update of EULAR's RA management recommendation.
INTRODUCTION: Synthesis of evidence on the long-term use of first-line biologic therapy in patients with early rheumatoid arthritis (RA) is required. We compared the efficacy of up to 5 years' treatment with first-line tumor necrosis factor inhibitors (TNFis) versus other treatment strategies in this population.
METHODS: Previous systematic reviews, PubMed and the Cochrane Central Register of Controlled Trials were searched for randomized controlled trials (RCTs) involving treatment of methotrexate-naïve RA patients with first-line TNFis. Literature was synthesized qualitatively, and a meta-analysis conducted to evaluate American College of Rheumatology (ACR) responses, clinical remission defined by any standard measure, and Health Assessment Questionnaire Disability Index (HAQ) at Years 2 and/or 5.
RESULTS: Ten RCTs involving 4306 patients [first-line TNFi, n = 2234; other treatment strategies (control), n = 2072] were included in the meta-analysis. Three studies were double-blind for the first 2 years, while seven were partly/completely open label during this period. Five studies reported data at Year 5; all were open label at this time point. At Year 2, ACR50 response, ACR70 response and remission rates were significantly improved with first-line TNFi versus control in double-blind RCTs [log-odds ratio (OR) 0.32 [95% confidence interval (CI) 0.02, 0.62; p = 0.035], log-OR 0.48 (95% CI 0.20, 0.77; p = 0.001), and log-OR 0.44 (95% CI 0.13, 0.74; p = 0.005), respectively], but not in open-label studies. No significant between-group differences were observed in mean HAQ at Year 2 in double-blind or open-label RCTs or in ACR response or remission outcomes at Year 5.
CONCLUSION: In double-blind studies, 2-year efficacy outcomes were significantly improved with first-line TNFi versus other treatment strategies in patients with MTX-naïve RA. No significant differences in these outcomes were observed when data from open-label RCTs were considered on their own. Further data on the efficacy of TNFi therapy over ≥ 2 years in patients with methotrexate-naïve RA are required. Plain language summary available for this article.
OBJECTIVES: Compare the benefits and harms of drug therapies for adults with early rheumatoid arthritis (RA) within 1 year of diagnosis, updating the findings on early RA from the 2012 review.
DATA SOURCES: English-language articles identified through MEDLINE®, Cochrane Library, Embase®, International Pharmaceutical Abstracts, gray literature, the previous 2012 review, expert recommendations, reference lists of published literature, and supplemental evidence data requests from January 2011 to October 5, 2017.
REVIEW METHODS: Literature was synthesized qualitatively in narrative form and summary tables within and between corticosteroids and classes of disease-modifying antirheumatic drugs (DMARDs). Additionally, combination treatment strategies were examined. We conducted network meta-analysis for five outcomes: American College of Rheumatology 50-percent improvement (ACR50), remission based on Disease Activity Score (DAS), radiographic joint damage, all discontinuations, and discontinuations due to adverse events. Eligibility for network meta-analyses required the following: (1) patients with early RA had not attempted prior treatment with methotrexate (MTX), (2) doses of treatments were within ranges approved by the Food and Drug Administration (FDA), (3) length of followup was similar, and (4) studies were double-blinded randomized controlled trials of low or medium risk of bias.
RESULTS: We analyzed 49 studies: 41 RCTs and 8 observational studies reported in 124 published articles. All included studies enrolled patients with moderate to high disease activity at baseline as measured with mean or median DAS 28 scores. A combination of corticosteroids plus MTX achieved higher remission rates than with MTX monotherapy (low strength of evidence [SOE]). Combination therapy with TNF (tumor necrosis factor) or non-TNF biologics plus MTX improved disease control, remission, and functional capacity compared with monotherapy with either MTX or a biologic (low to moderate SOE). Network meta-analyses found higher ACR50 response for combination therapy of biologics plus MTX than for MTX monotherapy (range of relative risk, 1.20 [95% confidence interval (CI), 1.04 to 1.38] to 1.57 [95% CI, 1.30 to 1.88]). In available data, consisting mostly of clinical trials, no significant differences emerged between any DMARDs for rates of discontinuation attributable to adverse events or serious adverse events (low SOE for adalimumab, certolizumab pegol, etanercept, infliximab, or abatacept with MTX, and moderate SOE for rituximab or tocilizumab with MTX). Data about subgroups (based on disease activity, prior therapy, demographics, and the presence of other serious conditions) were insufficient. No difference in findings were noted in MTX naïve and resistant populations. We found no studies of biosimilars for patients with early RA.
CONCLUSIONS: Qualitative synthesis and network meta-analyses suggest that the combination of MTX with TNF or non-TNF biologics improves disease activity and remission when compared with biologic monotherapy or a conventional synthetic DMARD (csDMARD) monotherapy in patients with moderate to high disease activity at baseline as measured with mean or median DAS 28 scores. Overall rates of adverse events and discontinuation were similar among patients given csDMARDs, TNF biologics, and non-TNF biologics. We did not find eligible studies of biosimilars.
