Abstract
BACKGROUND Reports on treatment patterns of biologic disease-modifying antirheumatic drugs (bDMARDs)/Janus kinase inhibitors (JAKi) for rheumatoid arthritis (RA) in clinical practice are still sparse in Japan, especially in combination with conventional synthetic DMARDs (csDMARDs). OBJECTIVES The aim of this study was to investigate treatment patterns of bDMARD/JAKi in the treatment of RA in real-world clinical practice in Japan. METHOD A retrospective cohort study was conducted using the Japanese Medical Data Vision health claims database. The inclusion criteria required a recorded diagnosis of RA, defined by ICD-10 codes, in patients aged 18 years and older on the index date. We analyzed 39,903 RA patients treated with DMARDs from 2008 to 2020. RESULTS Among analyzed subjects, 10,196 patients (25.6%) were prescribed bDMARDs/JAKi in combination with csDMARDs, and 3067 patients (7.7%) were prescribed these drugs without csDMARDs. Among the bDMARDs/JAKi, tumor necrosis factor inhibitors (TNFi) were the most commonly prescribed DMARD overall, and also the most common first-line therapy, accounting for 60.0% or 45.5% of patients prescribed these drugs in combination with or without csDMARDs, respectively. Switching, temporary discontinuation (restarting with the same agents), and discontinuation of bDMARDs/JAKi were observed in 3150 (30.9%), 1379 (13.5%), and 2025 (19.9%) patients with csDMARDs, and in 849 (27.7%), 513 (16.7%), and 833 (27.2%) patients without csDMARDs, respectively. CONCLUSIONS Real-world treatment trajectories of bDMARDs/JAKi with and without csDMARDs was analyzed in RA patients in Japan between 2008 and 2020. TNFi were the predominant first-line therapy, and likely to be switched to different classes. Understanding the current treatment patterns, including discontinuation, is important to find an optimal treatment strategy for RA patients.

[PMID: 37415053 PMCID: PMC10497429 DOI: 10.1007/s10067-023-06659-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 05/17/2023] [Accepted: 06/01/2023] [Indexed: 07/08/2023]
Abstract
INTRODUCTION The therapy of rheumatoid arthritis (RA) was advanced by biological agents, yet costly. This study aims to identify the effective threshold dose of etanercept (ENT) and cost-effectiveness in methotrexate (MTX)-resistant RA in real world. METHODS Eligible patients had an inadequate response (DAS28-ESR > 3.2) to initial MTX monotherapy, and subsequently received etanercept. The effective cut-off value of cumulative dose was identified to maintain remission response (DAS28-ESR < 2.6) at month 24 by using restricted cubic splines. Remission rate, low disease activity (LDA) rate, glucocorticoid exposure, safety, and cost-effectiveness were compared between the saturated and non-saturated dose groups divided by the cut-off dose. RESULTS Seventy-eight (14.2%) of 549 enrolled patients were eligible, and 72 patients completed follow-up. The 2-year cumulative cut-off dose that maintained remission response at 24 months was 1975 mg. And the recommended threshold dosing strategy of etanercept was twice weekly (BIW) for the first 6 months, every week (QW) for the next 6 months, and every 2 weeks (Q2W) and every month (QM) for the second year. Greater net changes in DAS28-ESR score were observed in the ENT saturated dose group than in the non-saturated dose group (average change 0.569, 95%CI 0.236-0.901, p = 0.001). The proportion of patients achieving remission (27.8% vs 72.2%, p < 0.001) and LDA (58.3% vs 83.3%, p = 0.020) in the non-saturated group was both significantly lower than that in the saturated group at 24 months. The incremental cost-effectiveness ratio of the saturated group referred to the non-saturated group was 5791.2 $/QALY. CONCLUSIONS In refractory RA patients, the effective cumulative cut-off dose of etanercept for sustained remission at 24 months was calculated as 1975 mg, and receiving saturated dose was more effective and cost-effective than with non-saturated dose. Key Points • The effective cumulative cut-off dose of etanercept for sustained remission at 24 months in RA patients is calculated as 1975 mg. • Receiving saturated dose of etanercept is more effective and cost-effective than with non-saturated dose in refractory RA patients.

EULAR recommendations for the management of rheumatoid arthritis with synthetic and biological disease-modifying antirheumatic drugs: 2022 update. Ann Rheum Dis 2023; 82:3-18.

Abstract
OBJECTIVES To provide an update of the EULAR rheumatoid arthritis (RA) management recommendations addressing the most recent developments in the field. METHODS An international task force was formed and solicited three systematic literature research activities on safety and efficacy of disease-modifying antirheumatic drugs (DMARDs) and glucocorticoids (GCs). The new evidence was discussed in light of the last update from 2019. A predefined voting process was applied to each overarching principle and recommendation. Levels of evidence and strengths of recommendation were assigned to and participants finally voted on the level of agreement with each item. RESULTS The task force agreed on 5 overarching principles and 11 recommendations concerning use of conventional synthetic (cs) DMARDs (methotrexate (MTX), leflunomide, sulfasalazine); GCs; biological (b) DMARDs (tumour necrosis factor inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab including biosimilars), abatacept, rituximab, tocilizumab, sarilumab and targeted synthetic (ts) DMARDs, namely the Janus kinase inhibitors tofacitinib, baricitinib, filgotinib, upadacitinib. Guidance on monotherapy, combination therapy, treatment strategies (treat-to-target) and tapering in sustained clinical remission is provided. Safety aspects, including risk of major cardiovascular events (MACEs) and malignancies, costs and sequencing of b/tsDMARDs were all considered. Initially, MTX plus GCs is recommended and on insufficient response to this therapy within 3-6 months, treatment should be based on stratification according to risk factors; With poor prognostic factors (presence of autoantibodies, high disease activity, early erosions or failure of two csDMARDs), any bDMARD should be added to the csDMARD; after careful consideration of risks of MACEs, malignancies and/or thromboembolic events tsDMARDs may also be considered in this phase. If the first bDMARD (or tsDMARD) fails, any other bDMARD (from another or the same class) or tsDMARD (considering risks) is recommended. With sustained remission, DMARDs may be tapered but should not be stopped. Levels of evidence and levels of agreement were high for most recommendations. CONCLUSIONS These updated EULAR recommendations provide consensus on RA management including safety, effectiveness and cost.

Abstract
OBJECTIVE To systematically review possible predictors of successful discontinuation of biologic or targeted synthetic DMARDs (b/tsDMARDs) in RA patients in remission or low disease activity. METHODS MEDLINE database and Cochrane Library were scanned for studies that discontinued b/tsDMARDs in remission/low disease activity and searched for predictors of successful discontinuation. Additionally, EULAR and ACR meeting abstracts were hand searched. RESULTS Thirty-four studies with a total of 5724 patients were included. Predictors of successful b/tsDMARD discontinuation were (number of studies): low disease activity (n = 13), better physical function (n = 6), low or absence of rheumatoid factor (n = 5) or ACPA (n = 3), low levels of CRP (n = 3) or ESR (n = 3), shorter disease duration (n = 3), low signals of disease activity by ultrasound (n = 3). Only one study with high risk of bias was identified on tsDMARD discontinuation. CONCLUSION Several predictors of successful bDMARD discontinuation were identified. Although studies are heterogeneous, these predictors may inform clinical decision making in patients who are considered for a potential bDMARD discontinuation.

Abstract
Background Strategic drug therapy for rheumatoid arthritis (RA) patients with prolonged remission is not well defined. According to recent guidelines, tapering biological Disease-Modifying Anti-Rheumatic Drugs (bDMARDs) may be considered. We aimed to evaluate the effectiveness of long-term maintenance of tocilizumab (TCZ) treatment after the progressive tapering of infusions. Methods We conducted an exploratory, prospective, single-center, open-label study, on RA patients with sustained remission of at least 3 months and treated with TCZ infusions every 4 weeks. The initial re-treatment interval was extended to 6 weeks for the first 3 months. Thereafter, the spacing between infusions was determined by the clinician. Successful long-term maintenance following the tapering of TCZ infusions was defined by patients still treated after two years by TCZ with a minimum dosing interval of 5 weeks. Results Thirteen patients were enrolled in the study. Eight out of thirteen were still treated by TCZ after two years. Successful long-term maintenance was possible in six patients, with four patients maintaining a re-treatment interval of 8-weeks or more. We observed 5 patients with TCZ withdrawal: one showing adverse drug reaction (neutropenia) and four with secondary failure. Patients achieving successful long-term maintenance with TCZ were significantly younger than those with secondary failure (p < 0.05). In addition, RA patients with positive rheumatoid factor and anti-citrullinated peptide antibodies, experienced a significantly greater number of flares during our 2-year follow-up (p < 0.01). Conclusions A progressive tapering of TCZ infusions may be possible for many patients. However, larger studies, including more patients, are needed to confirm this therapeutic option. Trial registration NCT02909998. Date of registration: October 2008.

Abstract
Introduction: Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease, which affects joints as well as extra-articular tissues. In the last decades, increasing targeted therapeutic options dramatically improved RA management by doubling the rate of patients achieving clinical remission. Currently, there is a need for management strategies aimed at limiting treatment-related adverse events and costs in good responders.Areas covered: Data on de-escalation of biologic drugs (especially for anti-TNF agents) are mainly available from post-hoc analyses of randomized controlled trials and from registry-based observational studies. This narrative review illustrates the rationales for dose tapering and expands to provide an overview of the efficacy of the different available strategies for reducing the exposure to biologic drugs in patients achieving a sustained clinical response. Selected studies are discussed as illustrative examples.Expert opinion: Withdrawal of biologic therapy might be attempted in limited patients with very early RA; conversely, established RA is more suitably managed with a progressive decrease of drug regimen, by either dose reduction or injection/infusion spacing. Further studies investigating potential factors predicting post-tapering disease relapse are warranted, in order to better identify the best candidates for a decreased-dose approach.

Abstract
The expanding range of treatment options for rheumatoid arthritis (RA), from conventional synthetic disease-modifying antirheumatic drugs (DMARDs) to biological DMARDs (bDMARDs), biosimilar bDMARDs, and targeted synthetic DMARDs, has improved patient outcomes but increased the complexity of treatment decisions. These updated consensus recommendations from the Hong Kong Society of Rheumatology provide guidance on the management of RA, with a focus on how to integrate newly available DMARDs into clinical practice. The recommendations were developed based on evidence from the literature along with local expert opinion. Early diagnosis of RA and prompt initiation of effective therapy remain crucial and we suggest a treat-to-target approach to guide optimal sequencing of DMARDs in RA patients to achieve tight disease control. Newly available DMARDs are incorporated in the treatment algorithm, resulting in a greater range of second-line treatment options. In the event of treatment failure or intolerance, switching to another DMARD with a similar or different mode of action may be considered. Given the variety of available treatments and the heterogeneity of patients with RA, treatment decisions should be tailored to the individual patient taking into consideration prognostic factors, medical comorbidities, drug safety, cost of treatment, and patient preference.

Abstract
Objective To evaluate the sustained remission and low disease activity after discontinuation of tocilizumab in patients with rheumatoid arthritis who were treated with tocilizumab alone or in combination with methotrexate. Methods The SURPRISE study was a 2-year, open-label randomised controlled study. Among patients who had been randomised to additional tocilizumab (ADD-ON) or switch to tocilizumab (SWITCH) in the first year, those who achieved remission based on the disease activity score for 28 joints (DAS28-ESR<2.6) discontinued tocilizumab at week 52 and were observed for the following 52 weeks. The endpoint of the second year included tocilizumab-free remission and low disease-activity rates, functional outcome, radiological outcomes assessed with the modified total Sharp score (mTSS) and safety. The efficacy of reinstituted tocilizumab/methotrexate was also evaluated. Results A total of 105 patients who achieved remission at week 52 discontinued tocilizumab; 51 in ADD-ON continued methotrexate and 54 in SWITCH received no disease-modifying antirheumatic drugs. Sustained DAS28 low disease-activity rates were significantly higher in ADD-ON than in SWITCH (55%vs27%, p=0.005). Sustained remission rates at week 104 were 24% for ADD-ON and 14% for SWITCH (p=0.29). Radiological progression was comparable between both groups (mTSS; 0.37vs0.64, p=0.36). The restart of tocilizumab induced remission in all except two patients after 36 weeks, irrespective of concomitant methotrexate. Conclusion Sustained low disease activity after tocilizumab discontinuation could be maintained with continued methotrexate in more than half of the patients. Retreatment with tocilizumab led to remission in more than 90% of patients. Trial registration number NCT01120366; Results.

Abstract
Objectives As data on disease-activity-guided dose optimization of abatacept and tocilizumab are scarce, we explored the feasibility, effectiveness and safety of dose optimization of these biological DMARDs in RA patients in daily practice. Methods RA patients who had been treated with abatacept or tocilizumab for ≥6 months, with DAS28 <3.2, were included. Four groups were identified: abatacept dose reduction (DR) and usual care (UC), and tocilizumab DR and UC. Successful DR and discontinuation entailed being on a lower dose than at baseline or having discontinued abatacept or tocilizumab, while maintaining disease activity score with ESR using 28 joint count (DAS28) <3.2. Proportions of patients with successful DR or discontinuation at 12 months were described. Maintenance of DR was investigated using Kaplan-Meier curves. Between-group differences in mean DAS28 and Health assessment questionnaire disability index (HAQ-DI) change (Δ) over 6 and 12 months were estimated. Results One hundred and nineteen patients were included. DR was attempted in 13 of 28 (46%; 95% CI: 28, 66%) abatacept and 64 of 91 (70%; 95% CI: 60, 79%) tocilizumab patients. At 12 months, 3 of 11 (27%; 95% CI: 6, 61%) abatacept and 20 of 48 (42%; 95% CI: 28, 57%) tocilizumab patients were successfully tapered. One of 11 (9%; 95% CI: 0, 41%) abatacept and 5 of 48 (10%; 95% CI: 3, 23%) tocilizumab patients were successfully discontinued. Mean ΔDAS28 and ΔHAQ-DI at months 6 and 12 were not significantly different between DR and UC. For tocilizumab, DAS28 was significantly higher in the DR compared with the UC group at 6 months. Adverse events were comparable between groups. Conclusion Abatacept and tocilizumab DR appears to be feasible and safe in clinical practice. No benefits in terms of fewer adverse events in the DR group were observed. Furthermore, DR was suboptimal, because all patients were eligible for DR, but in a substantial number of patients no DR was attempted.

Abstract
BACKGROUND Synovitis (inflamed joint synovial lining) in rheumatoid arthritis (RA) can be assessed by clinical examination (CE) or ultrasound (US). OBJECTIVE To investigate the added value of US, compared with CE alone, in RA synovitis in terms of clinical effectiveness and cost-effectiveness. DATA SOURCES Electronic databases including MEDLINE, EMBASE and the Cochrane databases were searched from inception to October 2015. REVIEW METHODS A systematic review sought RA studies that compared additional US with CE. Heterogeneity of the studies with regard to interventions, comparators and outcomes precluded meta-analyses. Systematic searches for studies of cost-effectiveness and US and treatment-tapering studies (not necessarily including US) were undertaken. MATHEMATICAL MODEL A model was constructed that estimated, for patients in whom drug tapering was considered, the reduction in costs of disease-modifying anti-rheumatic drugs (DMARDs) and serious infections at which the addition of US had a cost per quality-adjusted life-year (QALY) gained of £20,000 and £30,000. Furthermore, the reduction in the costs of DMARDs at which US becomes cost neutral was also estimated. For patients in whom dose escalation was being considered, the reduction in number of patients escalating treatment and in serious infections at which the addition of US had a cost per QALY gained of £20,000 and £30,000 was estimated. The reduction in number of patients escalating treatment for US to become cost neutral was also estimated. RESULTS Fifty-eight studies were included. Two randomised controlled trials compared adding US to a Disease Activity Score (DAS)-based treat-to-target strategy for early RA patients. The addition of power Doppler ultrasound (PDUS) to a Disease Activity Score 28 joints-based treat-to-target strategy in the Targeting Synovitis in Early Rheumatoid Arthritis (TaSER) trial resulted in no significant between-group difference for change in Disease Activity Score 44 joints (DAS44). This study found that significantly more patients in the PDUS group attained DAS44 remission (p = 0.03). The Aiming for Remission in Rheumatoid Arthritis (ARCTIC) trial found that the addition of PDUS and grey-scale ultrasound (GSUS) to a DAS-based strategy did not produce a significant between-group difference in the primary end point: composite DAS of < 1.6, no swollen joints and no progression in van der Heijde-modified total Sharp score (vdHSS). The ARCTIC trial did find that the erosion score of the vdHS had a significant advantage for the US group (p = 0.04). In the TaSER trial there was no significant group difference for erosion. Other studies suggested that PDUS was significantly associated with radiographic progression and that US had added value for wrist and hand joints rather than foot and ankle joints. Heterogeneity between trials made conclusions uncertain. No studies were identified that reported the cost-effectiveness of US in monitoring synovitis. The model estimated that an average reduction of 2.5% in the costs of biological DMARDs would be sufficient to offset the costs of 3-monthly US. The money could not be recouped if oral methotrexate was the only drug used. LIMITATIONS Heterogeneity of the trials precluded meta-analysis. Therefore, no summary estimates of effect were available. Additional costs and health-related quality of life decrements, relating to a flare following tapering or disease progression, have not been included. The feasibility of increased US monitoring has not been assessed. CONCLUSION Limited evidence suggests that US monitoring of synovitis could provide a cost-effective approach to selecting RA patients for treatment tapering or escalation avoidance. Considerable uncertainty exists for all conclusions. Future research priorities include evaluating US monitoring of RA synovitis in longitudinal clinical studies.

Abstract
OBJECTIVES To prospectively evaluate the efficacy and tolerability of a six-week extended dosing interval with tocilizumab (TCZ) in patients with rheumatoid arthritis (RA) in sustained remission. METHODS Patients who received over six doses of intravenous TCZ in clinical remission (disease activity score [DAS] 28 - erythrocyte sedimentation rate [ESR] ≤ 2.6) maintained over 3 months between December 2013 and December 2015 were included. Flare was defined as DAS28-ESR >3.2 at two consecutive visits. RESULTS Twenty-five patients were enrolled; 87.5% achieved clinical remission at week 54 after six-week extension and 95.5% achieved a van der Heijde modified total Sharp score (ΔmTSS) ≤0.5. The Health Assessment Questionnaire Disability Index (HAQ-DI) did not increase during 54 weeks. HAQ-DI at baseline and ΔDAS28-ESR at week six positively correlated with increase in DAS28-ESR at week 54. ΔSwollen joint count at week six positively correlated with ΔmTSS at week 54. A total of 12 adverse events occurring in 10 patients did not lead to cessation of TCZ except for one case of recurrent lymphoproliferative disorder at week five. CONCLUSION A six-week extended dosing interval of TCZ for patients with RA in sustained remission is proposed as an acceptable treatment option for maintaining efficacy and tolerability.

Abstract
OBJECTIVE To systematically review studies addressing prediction of successful dose reduction or discontinuation of a biologic agent in rheumatoid arthritis (RA). METHODS PubMed, Embase, and Cochrane Library databases were searched for studies that examined the predictive value of biomarkers for successful dose reduction or discontinuation of a biologic agent in RA. Two reviewers independently selected studies, and extracted data and assessed the risk of bias. A biomarker was classified as a "potential predictor" if the univariate association was either strong (odds ratio or hazard ratio >2.0 or <0.5) or statistically significant. For biomarkers that were studied multiple times, qualitative best-evidence synthesis was performed separately for the prediction of successful dose reduction and discontinuation. Biomarkers that were defined in ≥75% of the studies as potential predictors were regarded as "predictor" for the purposes of our study. RESULTS Of 3,029 nonduplicate articles initially searched, 16 articles regarding 15 cohorts were included in the present study. Overall, 17 biomarkers were studied multiple times for the prediction of successful dose reduction, and 33 for the prediction of successful discontinuation of a biologic agent. Three predictors were identified: higher adalimumab trough level for successful dose reduction and lower Sharp/van der Heijde erosion score and shorter symptom duration at the start of a biologic agent for successful discontinuation. CONCLUSION The predictive value of a wide variety of biomarkers for successful dose reduction or discontinuation of biologic treatment in RA has been investigated. We identified only 3 biomarkers as predictors, in just 2 studies. The strength of the evidence is limited by the low quality of the included studies and the likelihood of reporting bias and multiple testing.

Abstract
Introduction Although bDMARDs are effective in the treatment of RA, they are associated with dose-dependent side effects, patient burden, and high costs. Recently, many studies have investigated the possibility of discontinuing or tapering bDMARDs when patients have reached their treatment goal. The aim of this review is to provide a narrative overview of the existing evidence on bDMARD dose reduction and to provide answers to specific dose-reduction-related questions that are of interest to clinicians. Methods We systematically searched for relevant studies in four scientific databases. Furthermore, we screened the references of reviews and relevant studies. Results Our searches resulted in 45 original studies of bDMARD dose reduction in RA patients (15 RCTs and 30 observational studies). Current evidence shows that bDMARD dose reduction can be considered in all RA patients who achieve stable (e.g., ≥6 months) low disease activity or remission. The best strategies seem to be disease-activity-guided dose optimization and fixed dose reduction, since direct bDMARD discontinuation (without restarting) results in a high flare rate, worse physical functioning, and more joint damage. When tapering the bDMARD treatment of a patient, disease activity should be monitored closely, and if a flare occurs, the dose should be increased to the lowest effective dose. Current evidence shows that restarting bDMARD treatment is effective and safe. Unfortunately, no clear predictors of successful dose reduction have been identified so far. Conclusion The current evidence and rising healthcare costs urge that dose reduction should be considered for eligible patients. However, the decision to start dose reduction should be made in shared decision-making. Future research should focus not only on a better understanding of the effects of dose reduction on clinical outcomes but also on the perspectives of patients and physicians as well as the implementation of this new treatment principle.

Abstract
As more patients with established rheumatoid arthritis (RA) achieve remission or low disease activity, strategies such as tapering and withdrawal of disease-modifying antirheumatic drugs (DMARDs) are being investigated. In several trials, DMARD discontinuation was associated with a higher risk of relapse, ranging from 56% to 87% at 1 year. Tapering, either by dose reduction or by injection spacing, may limit the risk of relapse. Half-dose etanercept (ETN) versus full-dose continuation was not associated with an increased relapse risk at 1 year in two trials. Progressive antitumor necrosis factor injection spacing was shown to be equivalent to full regimen continuation in terms of persistent flare and disease activity at 18 months in one trial, but not in another one. Reintroduction of a DMARD at previous dose/regimen was usually associated with remission re-induction. The risk of relevant structural damage progression was not increased. Safety improvement has not yet been demonstrated. The annual cost reduction when tapering biologic DMARDs (bDMARDs) was 3500-6000 €/patient. Research questions to be addressed include defining flare that requires reinitiation of treatment, such that patients facilitate the maintenance of remission during tapering by timely communication with their rheumatology team.

Abstract
Objective.To evaluate the risk of having a disease flare in patients with rheumatoid arthritis (RA) with low disease activity (LDA) or in remission when deescalating (tapering or stopping) disease-modifying antirheumatic drug (DMARD) therapy.Methods.A search in medical databases including publications from January 1950 to February 2015 was performed. Included were trials and observational studies in adults with RA who were in LDA or remission, evaluating ≥ 20 patients tapering or stopping DMARD. Flare rates had to have been reported. A metaanalysis was performed on studies deescalating tumor necrosis factor (TNF) blockers.Results.Four studies evaluated synthetic DMARD. Flare rates ranged from 8% at 24 weeks to 63% at 4 months after deescalation. Fifteen studies reported on TNF blockers. Estimated flare rates by metaanalysis on studies tapering or stopping TNF blockers were 0.26 (95% CI 0.17–0.39) and 0.49 (95% CI 0.27–0.73) for good-quality and moderate-quality studies, respectively. Flare rates in 3 studies stopping tocilizumab were 41% after 6 months, 55% at 1 year, and 87% at 1 year. Flare rates in 3 studies deescalating abatacept were 34% at 1 year, 41% at 1 year, and 72% at 6 months. Five studies evaluating radiographic progression in patients deescalating treatment all found limited to no progression.Conclusion.Results suggest that more than one-third of patients with RA with LDA or in remission may taper or stop DMARD treatment without experiencing a disease flare within the first year. Dose reduction of TNF blockers results in lower flare rates than stopping and may be noninferior to continuing full dose. Radiological progression after treatment deescalation remains low, but may increase slightly.

Abstract
Tocilizumab (TCZ) is a humanized monoclonal antibody against the IL-6 receptor that is indicated for the treatment of rheumatoid arthritis (RA), juvenile idiopathic arthritis and Castleman's disease. TCZ was developed as an intravenous (IV) formulation and approved for RA treatment in Japan (2008), the EU (2009) and the USA (2010). Recently, a subcutaneous (SC) formulation of TCZ was developed and approved for RA treatment. Efficacy and safety of TCZ-SC were reported through three randomized trials: MUSASHI, SUMMACTA and BREVACTA. Clinical efficacy and overall safety of TCZ-SC was comparable to that of TCZ-IV. However TCZ-SC, which is provided in a fixed dose, the efficacy was affected by patient weight. The frequencies of injection site reactions and anti-TCZ antibodies were increased with TCZ-SC compared with TCZ-IV, although differences were minimal and at a negligible level for daily clinical practice. This review highlights the potential of TCZ-SC in RA treatment.

Abstract
UNLABELLED Tumour necrosis factor (TNF)-blocker tapering has been proposed for patients with rheumatoid arthritis (RA) in remission. OBJECTIVE The trial aims to compare the effect of progressive spacing of TNF-blocker injections (S-arm) to their maintenance (M-arm) for established patients with RA in remission. METHODS The study was an 18-month equivalence trial which included patients receiving etanercept or adalimumab at stable dose for ≥1 year, patients in remission on 28-joint Disease Activity Score (DAS28) for ≥6 months and patients with stable joint damage. Patients were randomised into two arms: maintenance or injections spacing by 50% every 3 months up to complete stop. Spacing was reversed to the previous interval in case of relapse, and eventually reattempted after remission was reachieved. The primary outcome was the standardised difference of DAS28 slopes, based on a linear mixed-effects model (equivalence interval set at ±30%). RESULTS 64 and 73 patients were included in the S-arm and M-arm, respectively, which was less than planned. In the S-arm, TNF blockers were stopped for 39.1%, only tapered for 35.9% and maintained full dose for 20.3%. The equivalence was not demonstrated with a standardised difference of 19% (95% CI -5% to 46%). Relapse was more common in the S-arm (76.6% vs 46.5%, p=0.0004). However, there was no difference in structural damage progression. CONCLUSIONS Tapering was not equivalent to maintenance strategy, resulting in more relapses without impacting structural damage progression. Further studies are needed to identify patients who could benefit from such a strategy associated with substantial cost savings. TRIAL REGISTRATION NUMBER ClinicalTrials.gov: NCT00780793; EudraCT identifier: 2007-004483-41.

Abstract
The complex interaction of molecules within a biological system constitutes a functional module. These modules are then acted upon by both internal and external factors, such as genetic and environmental stresses, which under certain conditions can manifest as complex disease phenotypes. Recent advances in high-throughput biological analyses, in combination with improved computational methods for data enrichment, functional annotation, and network visualization, have enabled a much deeper understanding of the mechanisms underlying important biological processes by identifying functional modules that are temporally and spatially perturbed in the context of disease development. Systems biology approaches such as these have produced compelling observations that would be impossible to replicate using classical methodologies, with greater insights expected as both the technology and methods improve in the coming years. Here, we examine the use of systems biology and network analysis in the study of a wide range of rheumatic diseases to better understand the underlying molecular and clinical features.

Abstract
BackgroundThere is increasing interest in discontinuing biological therapies for patients with rheumatoid arthritis (RA) achieving good clinical responses, provided patients maintain clinical benefit.MethodsWe assessed patients with RA from the Corrona registry who discontinued treatment with their first tumour necrosis factor inhibitor (TNFi) while in low-disease activity (LDA) or lower levels of disease activity. Patients were followed until they lost clinical benefit, defined as increased disease activity or change in RA medications. Duration of maintenance of clinical benefit was estimated using the Kaplan–Meier method. Cox proportional hazard models were assessed to identify factors related to maintenance of benefit.ResultsWe identified 717 eligible patients with RA from 35 656 in the Corrona registry. At discontinuation, patients had a median RA duration of 8 years, mean clinical disease activity score of 4.3±0.11; 41.8% were using TNFi as monotherapy. 73.4% of patients maintained benefit for >12 months after discontinuing therapy and 42.2% did so through 24 months. Factors predictive of maintaining clinical benefit in multivariate analysis included lower disease activity, less pain and better functional status at the time of TNFi discontinuation. Among 301 patients initiating their first TNFi within the registry, faster responders (ie, those who achieved LDA in 4 months or less) did better than slower responders (HR 1.54 (95% CI 1.17 to 2.04)). RA disease duration did not affect maintenance of clinical benefit.ConclusionsDiscontinuation of a first course of TNFi may be associated with persistent clinical benefit. Half of patients maintained response through 20 months. Several patient characteristics may help predict persistent benefit.

Abstract
Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by inflammation and joint destruction that causes significant morbidity and mortality. However, the combined use of methotrexate (MTX), a synthetic disease-modifying anti-rheumatic drug (sDMARD) and biological DMARDs (bDMARDs) has revolutionized treatment of RA and clinical remission or low disease activity (LDA) are now realistic targets, achieved by a large proportion of RA patients. We are now in a position to evaluate if it is possible to maintain remission or LDA while at the same time reducing the burden of treatment on the patient and healthcare system. Data are emerging from large, well-conducted studies designed to answer this question, shedding light on which patient populations and treatment algorithms can survive treatment discontinuation or tapering with low risk of disease flare. For early RA, approximately half of early RA patients could discontinue TNF-targeted bDMARDs without clinical flare and functional impairment after obtaining clinical remission by bDMARDs with MTX. In contrast, for established RA, fewer patients sustained remission or LDA after the discontinuation of bDMARDs and "deep remission" at the discontinuation was a key factor to maintain the treatment holiday of bDMARDs. Thus, this article provides a brief outline on withdrawing or tapering bDMARDs once patients have achieved remission or LDA in RA.

Abstract
Innate immune cells, particularly macrophages and epithelial cells, play a key role in multiple layers of immune responses. Alarmins and pro-inflammatory cytokines from the IL (interleukin)-1 and TNF (tumour necrosis factor) families initiate the cascade of events by inducing chemokine release from bystander cells and by the up-regulation of adhesion molecules required for transendothelial trafficking of immune cells. Furthermore, innate cytokines produced by dendritic cells, macrophages, epithelial cells and innate lymphoid cells seem to play a critical role in polarization of helper T-cell cytokine profiles into specific subsets of Th1/Th2/Th17 effector cells or regulatory T-cells. Lastly, the innate immune system down-regulates effector mechanisms and restores homoeostasis in injured tissue via cytokines from the IL-10 and TGF (transforming growth factor) families mainly released from macrophages, preferentially the M2 subset, which have a capacity to induce regulatory T-cells, inhibit the production of pro-inflammatory cytokines and induce healing of the tissue by regulating extracellular matrix protein deposition and angiogenesis. Cytokines produced by innate immune cells represent an attractive target for therapeutic intervention, and multiple molecules are currently being tested clinically in patients with inflammatory bowel disease, rheumatoid arthritis, systemic diseases, autoinflammatory syndromes, fibrosing processes or malignancies. In addition to the already widely used blockers of TNFα and the tested inhibitors of IL-1 and IL-6, multiple therapeutic molecules are currently in clinical trials targeting TNF-related molecules [APRIL (a proliferation-inducing ligand) and BAFF (B-cell-activating factor belonging to the TNF family)], chemokine receptors, IL-17, TGFβ and other cytokines.
