Abstract
INTRODUCTION Rheumatoid arthritis (RA) is a chronic autoimmune disease that significantly impacts patients' quality of life. While treatment options have expanded over the years, including the introduction of tumor necrosis factor-alpha (TNFα) inhibitors (TNFi), optimizing withdrawal strategies for these agents remains a challenge. AREAS COVERED This review examines the current evidence on TNFi withdrawal strategies in RA, focusing on factors influencing withdrawal decisions such as disease activity monitoring, treatment response, patient characteristics, and biomarkers. A comprehensive literature search was conducted, including randomized controlled trials, observational studies, and expert guidelines. The pathophysiology of RA, current pharmacological agents, and the treat-to-target strategy are discussed to provide a holistic understanding of RA management. EXPERT OPINION Withdrawal strategies could be suitable for certain patients, keeping in mind that several factors influence withdrawal decisions, including treatment response, disease activity and monitoring, and patient characteristics. The decision to withdraw TNFi must balance the benefits against the potential risks of disease flare and long-term treatment-related adverse effects. Combining DMARDs and TNFi early improves outcomes, supporting tapering strategies for cost-effectiveness and flare prevention. Future directions, including precision medicine approaches, patient-centered care models, and health economics analyses, are proposed to further optimize RA management and improve patient outcomes.

Ward MM, Madanchi N, Yazdanyar A, Shah NR, Constantinescu F. Prevalence and predictors of sustained remission/low disease activity after discontinuation of induction or maintenance treatment with tumor necrosis factor inhibitors in rheumatoid arthritis: a systematic and scoping review. Arthritis Res Ther 2023; 25:222. [PMID: 37986101 PMCID: PMC10659063 DOI: 10.1186/s13075-023-03199-0] [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: 07/26/2023] [Accepted: 10/20/2023] [Indexed: 11/22/2023] Open
Abstract
BACKGROUND To determine the prevalence of sustained remission/low disease activity (LDA) in patients with rheumatoid arthritis (RA) after discontinuation of tumor necrosis factor inhibitors (TNFi), separately in induction treatment and maintenance treatment studies, and to identify predictors of successful discontinuation. METHODS We performed a systematic literature review of studies published from 2005 to May 2022 that reported outcomes after TNFi discontinuation among patients in remission/LDA. We computed prevalences of successful discontinuation by induction or maintenance treatment, remission criterion, and follow-up time. We performed a scoping review of predictors of successful discontinuation. RESULTS Twenty-two induction-withdrawal studies were identified. In pooled analyses, 58% (95% confidence interval (CI) 45, 70) had DAS28 < 3.2 (9 studies), 52% (95% CI 35, 69) had DAS28 < 2.6 (9 studies), and 40% (95% CI 18, 64) had SDAI ≤ 3.3 (4 studies) at 37-52 weeks after discontinuation. Among patients who continued TNFi, 62 to 85% maintained remission. Twenty-two studies of maintenance treatment discontinuation were also identified. At 37-52 weeks after TNFi discontinuation, 48% (95% CI 38, 59) had DAS28 < 3.2 (10 studies), and 47% (95% CI 33, 62) had DAS28 < 2.6 (6 studies). Heterogeneity among studies was high. Data on predictors in induction-withdrawal studies were limited. In both treatment scenarios, longer duration of RA was most consistently associated with less successful discontinuation. CONCLUSIONS Approximately one-half of patients with RA remain in remission/LDA for up to 1 year after TNFi discontinuation, with slightly higher proportions in induction-withdrawal settings than with maintenance treatment discontinuation.

Abstract
Rheumatoid arthritis (RA) involves several classes of pathogenic autoantibodies, some of which react with type-II collagen (COL2) in articular cartilage. We previously described a subset of COL2 antibodies targeting the F4 epitope (ERGLKGHRGFT) that could be regulatory. Here, using phage display, we developed recombinant antibodies against this epitope and examined the underlying mechanism of action. One of these antibodies, R69-4, protected against cartilage antibody- and collagen-induced arthritis in mice, but not autoimmune disease models independent of arthritogenic autoantibodies. R69-4 was further shown to cross-react with a large range of proteins within the inflamed synovial fluid, such as the complement protein C1q. Complexed R69-4 inhibited neutrophil FCGR3 signaling, thereby impairing downstream IL-1β secretion and neutrophil self-orchestrated recruitment. Likewise, human isotypes of R69-4 protected against arthritis with comparable efficiency. We conclude that R69-4 abrogates autoantibody-mediated arthritis mainly by hindering FCGR3 signaling, highlighting its potential clinical utility in acute RA.

Effect of Golimumab Dose Escalation in Japanese Patients With Rheumatoid Arthritis: Post-Hoc Analysis of Post-Marketing Surveillance Data. Rheumatol Ther 2020; 7:311-325. [PMID: 32114644 PMCID: PMC7211224 DOI: 10.1007/s40744-020-00198-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Indexed: 01/13/2023] Open
Abstract
Introduction While dose escalation of golimumab has been used for patients with rheumatoid arthritis who demonstrate an inadequate response to the standard dose, its effectiveness has not been fully evaluated. The aim of this study was to assess the clinical outcome observed by dose escalation of golimumab for patients with rheumatoid arthritis in the daily clinical setting. Methods A post hoc analysis was performed of data from the 24-week post-marketing surveillance conducted in Japan (n = 5154). A total of 301 patients with moderate or high disease activity at baseline who underwent dose escalation of golimumab were assessed for effectiveness at 24 weeks based on several variables, such as DAS28-CRP, SDAI, and CDAI, as well as for medication persistence through 24 weeks. In addition, the study population was stratified by the time to dose escalation, and effectiveness was likewise evaluated. Logistic regression analysis was performed to identify factors associated with a moderate/good EULAR response to golimumab at 24 weeks. Results Patients with golimumab dose escalation showed significant improvement of the clinical signs and symptoms of rheumatoid arthritis at 24 weeks, as indicated by reduction of the DAS28-CRP (∆0.89), SDAI (∆8.64), and CDAI (∆8.28) scores. This result was relatively consistent across the subgroups stratified by the timing of dose escalation. According to Kaplan-Meier analysis, 78.1% of the patients continued to receive golimumab at 24 weeks, and this was also similar among the subgroups stratified by the time to dose escalation. Multivariate analysis identified male sex and previous biologic therapy as factors that were significantly associated with the clinical response at 24 weeks. Conclusion In real-world clinical practice, improvement of disease activity was observed after uptitration of golimumab from 50 to 100 mg regardless of the timing. Male patients and biologic-naive patients were more likely to respond to dose escalation of golimumab. Trial Registration UMIN-CTR, Identifier: UMIN000015895.

Abstract
OBJECTIVES The aim of this study is to determine whether the 'programmed' infliximab (IFX) treatment strategy (for which the dose of IFX was adjusted based on the baseline serum tumour necrosis factor α (TNF-α)) is beneficial to induction of clinical remission after 54 weeks and sustained discontinuation of IFX for 1 year. METHODS In this multicentre randomised trial, patients with IFX-naïve rheumatoid arthritis with inadequate response to methotrexate were randomised to two groups; patients in programmed treatment group received 3 mg/kg IFX until week 6 and after 14 weeks the dose of IFX was adjusted based on the baseline levels of serum TNF-α until week 54; patients in the standard treatment group received 3 mg/kg of IFX. Patients who achieved a simplified disease activity index (SDAI) ≤3.3 at week 54 discontinued IFX. The primary endpoint was the proportion of patients who sustained discontinuation of IFX at week 106. RESULTS A total of 337 patients were randomised. At week 54, 39.4% (67/170) in the programmed group and 32.3% (54/167) in the standard group attained remission (SDAI ≤3.3). At week 106, the 1-year sustained discontinuation rate was not significantly different between two groups; the programmed group 23.5% (40/170) and the standard group 21.6% (36/167), respectively (2.2% difference, 95% CI -6.6% to 11.0%; p=0.631). Baseline SDAI <26.0 was a statistically significant predictor of the successfully sustained discontinuation of IFX at week 106. CONCLUSION Programmed treatment strategy did not statistically increase the sustained remission rate after 1 year discontinuation of IFX treatment.

Abstract
Objective To investigate the clinical outcomes of rheumatoid arthritis (RA) patients who discontinued infliximab (IFX) treatment at our hospital. Methods Among 249 patients receiving IFX from 2007 to 2015, we retrospectively investigated the clinical courses of 18 who discontinued IFX after achieving the 28-joint disease activity score based on the erythrocyte sedimentation (DAS28-ESR) clinical remission (CR) and whose clinical courses were available continuously for 96 weeks after discontinuation. Results At IFX introduction, the median age was 56.9 (range 36.1-72.4) years, and the disease duration was 5.2 (0.4-25.6) years. The median duration of maintaining either CR or a low disease activity (LDA) with IFX was 37.2 (4.0-91.4) months, and the total duration of IFX therapy was 45.8 (17.1-96.9) months. After discontinuation, 8 patients (44.4%) maintained CR/LDA for 96 weeks (no-flare group), and 10 (55.6%) experienced flares (DAS28-ESR≥3.2) within 96 weeks (flare group). In the no-flare group, six patients receiving intensified conventional synthetic disease-modifying antirheumatic drug (csDMARD) therapy to prevent flare ups simultaneously either with or immediately after discontinuing IFX. In the flare group, four patients received intensified csDMARD therapy. Six patients restarted biological DMARDs (bDMARDs), and all achieved CR again. Ultimately, 12 patients (66.7%) maintained a Bio-free disease control for 96 weeks. A comparison of the clinical backgrounds between the flare and no-flare groups showed no marked difference in their disease duration, IFX dosage, duration of maintaining CR with IFX, or concomitant csDMARDs use. Conclusion Irrespective of the RA disease duration, more than half of all patients maintained a Bio-free condition for 96 weeks. Continuing LDA with IFX for a sufficiently long period of time before discontinuation and preventive intensification of csDMARD therapy may help maintain a Bio-free condition.

Abstract
Introduction: Early biological treatment of rheumatoid arthritis (RA) may reverse the autoimmune response in some patients resulting in favorable long-term outcomes. Although the cost-effectiveness of this strategy has been questioned, biosimilar entries warrant the revision of clinical and pharmaco-economic evidence. Areas covered: We conducted a systematic review of randomized controlled trials (RCTs) published up to 24 May 2018 in Pubmed, EMBASE and Cochrane CENTRAL, comparing infliximab with non-biological therapy in patients with RA naïve to methotrexate. We performed meta-analyses for efficacy outcomes at month 6 and years 1 and 2. Six RCTs were identified, involving 1832 patients. At month 6 ACR70 response and remission, and at year 1 ACR20/ACR70 responses and remission were improved significantly with first-line infliximab versus control. The differences were not significant at year 2. We reviewed cost-utility studies, up to 31 October 2018 in PubMed, Cochrane CENTRAL and the CRD HTA databases. Four studies indicated that first-line use of originator infliximab calculated at 2005-2008 prices was not cost-effective. Expert opinion: We demonstrated the efficacy benefits of first-line infliximab therapy up to 1 year in methotrexate-naïve RA. We highlighted the need for standardized reporting of outcomes and conducting cost-effectiveness analyses of first-line biosimilar therapy in RA.

Abstract
BACKGROUND Anti-tumour necrosis factor (TNF) agents are effective in treating people with rheumatoid arthritis (RA), but are associated with (dose-dependent) adverse effects and high costs. To prevent overtreatment, several trials have assessed the effectiveness of down-titration compared with continuation of the standard dose. This is an update of a Cochrane Review published in 2014. OBJECTIVES To evaluate the benefits and harms of down-titration (dose reduction, discontinuation, or disease activity-guided dose tapering) of anti-TNF agents on disease activity, functioning, costs, safety, and radiographic damage compared with usual care in people with RA and low disease activity. SEARCH METHODS We searched MEDLINE, Embase, Web of Science and CENTRAL (29 March 2018) and four trial registries (11 April 2018) together with reference checking, citation searching, and contact with study authors to identify additional studies. We screened conference proceedings (American College of Rheumatology and European League Against Rheumatism 2005-2017). SELECTION CRITERIA Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing down-titration (dose reduction, discontinuation, disease activity-guided dose tapering) of anti-TNF agents (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab) to usual care/no down-titration in people with RA and low disease activity. DATA COLLECTION AND ANALYSIS We used standard Cochrane methodology. MAIN RESULTS One previously included trial was excluded retrospectively in this update because it was not an RCT/CCT. We included eight additional trials, for a total of 14 studies (13 RCTs and one CCT, 3315 participants in total) reporting anti-TNF down-titration. Six studies (1148 participants) reported anti-TNF dose reduction compared with anti-TNF continuation. Eight studies (2111 participants) reported anti-TNF discontinuation compared with anti-TNF continuation (three studies assessed both anti-TNF discontinuation and dose reduction), and three studies assessed disease activity-guided anti-TNF dose tapering (365 participants). These studies included data on all anti-TNF agents, but primarily adalimumab and etanercept. Thirteen studies were available in full text, one was available as abstract. We assessed the included studies generally at low to moderate risk of bias; our main concerns were bias due to open-label treatment and unblinded outcome assessment. Clinical heterogeneity between the trials was high. The included studies were performed at clinical centres around the world and included people with early as well as established RA, the majority of whom were female with mean ages between 47 and 60. Study durations ranged from 6 months to 3.5 years.We found that anti-TNF dose reduction leads to little or no difference in mean disease activity score (DAS28) after 26 to 52 weeks (high-certainty evidence, mean difference (MD) 0.06, 95% confidence interval (CI) -0.11 to 0.24, absolute risk difference (ARD) 1%) compared with continuation. Also, anti-TNF dose reduction does not result in an important deterioration in function after 26 to 52 weeks (Health Assessment Questionnaire Disability Index (HAQ-DI)) (high-certainty evidence, MD 0.09, 95% CI 0.00 to 0.19, ARD 3%). Next to this, anti-TNF dose reduction may slightly reduce the proportion of participants switched to another biologic (low-certainty evidence), but probably slightly increases the proportion of participants with minimal radiographic progression after 52 weeks (moderate-certainty evidence, risk ratio (RR) 1.22, 95% CI 0.76 to 1.95, ARD 2% higher). Anti-TNF dose reduction may cause little or no difference in serious adverse events, withdrawals due to adverse events and proportion of participants with persistent remission (low-certainty evidence).Results show that anti-TNF discontinuation probably slightly increases the mean disease activity score (DAS28) after 28 to 52 weeks (moderate-certainty evidence, MD 0.96, 95% CI 0.67 to 1.25, ARD 14%), and that the RR of persistent remission lies between 0.16 and 0.77 (low-certainty evidence). Anti-TNF discontinuation increases the proportion participants with minimal radiographic progression after 52 weeks (high-certainty evidence, RR 1.69, 95% CI 1.10 to 2.59, ARD 7%) and may lead to a slight deterioration in function (HAQ-DI) (low-certainty evidence). It is uncertain whether anti-TNF discontinuation influences the number of serious adverse events (due to very low-certainty evidence) and the number of withdrawals due to adverse events after 28 to 52 weeks probably increases slightly (moderate-certainty evidence, RR 1.46, 95% CI 0.75 to 2.84, ARD 1% higher).Anti-TNF disease activity-guided dose tapering may result in little or no difference in mean disease activity score (DAS28) after 72 to 78 weeks (low-certainty evidence). Furthermore, anti-TNF disease activity-guided dose tapering results in little or no difference in the proportion of participants with persistent remission after 18 months (high-certainty evidence, RR 0.89, 95% CI 0.75 to 1.06, ARD -9%) and may result in little or no difference in switching to another biologic (low-certainty evidence). Anti-TNF disease activity-guided dose tapering may slightly increase proportion of participants with minimal radiographic progression (low-certainty evidence) and probably leads to a slight deterioration of function after 18 months (moderate-certainty evidence, MD 0.2 higher, 0.02 lower to 0.42 higher, ARD 7% higher), It is uncertain whether anti-TNF disease activity-guided dose tapering influences the number of serious adverse events due to very low-certainty evidence. AUTHORS' CONCLUSIONS We found that fixed-dose reduction of anti-TNF, after at least three to 12 months of low disease activity, is comparable to continuation of the standard dose regarding disease activity and function, and may be comparable with regards to the proportion of participants with persistent remission. Discontinuation (also without disease activity-guided adaptation) of anti-TNF is probably inferior to continuation of treatment with respect to disease activity, the proportion of participants with persistent remission, function, and minimal radiographic damage. Disease activity-guided dose tapering of anti-TNF is comparable to continuation of treatment with respect to the proportion of participants with persistent remission and may be comparable regarding disease activity.Caveats of this review are that available data are mainly limited to etanercept and adalimumab, the heterogeneity between studies, and the use of superiority instead of non-inferiority designs.Future research should focus on the anti-TNF agents infliximab and golimumab; assessment of disease activity, function, and radiographic outcomes after longer follow-up; and assessment of long-term safety, cost-effectiveness, and predictors for successful down-titration. Also, use of a validated flare criterion, non-inferiority designs, and disease activity-guided tapering instead of fixed-dose reduction or discontinuation would allow researchers to better interpret study findings and generalise to clinical practice.

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
Infliximab, an inhibitor of TNF-α, is one of the most widely used biological disease-modifying antirheumatic drugs. Recent studies indicated that baseline serum TNF-α could be considered as a key indicator for optimal dosing of infliximab for RA treatment to achieve the clinical response and its sustained remission. The Remission induction by Raising the dose of Remicade in RA (RRRR) study is an open-label, parallel group, multicenter randomized controlled trial to compare the proportions of clinical remission based on the simplified disease activity index (SDAI) after 1 year of treatment and its sustained remission rate after another 1 year between the investigational treatment strategy (for which the dose of infliximab was chosen based on the baseline serum TNF) and the standard strategy of 3 mg/kg per 8 weeks of infliximab administration in infliximab-naïve patients with RA showing an inadequate response to MTX. The primary endpoint is the proportion of patients who kept discontinuation of infliximab 1 year after discontinued infliximab at the time of 54 weeks after the first administration of infliximab. The secondary endpoints are the proportion of clinical remission based on SDAI and changes in SDAI from baseline at each time point, other clinical parameters, quality of life measures and adverse events. Target sample size of randomized patients is 400 patients in total. The main results of the RRRR study are expected to be published at the end of 2017.

Abstract
Sustained remission is an ultimate treatment goal in the management of patients with rheumatoid arthritis (RA). Historically the frequency of sustained remission was low but the frequency of achieved sustained remission is increasing over time. The last years’ clinical studies of tight control targeted treatment and intervention trials of early use of intensive strategy suggest that these treatment strategies are associated with higher rates of sustained remission. Achievement of sustained remission, in particular but not limited to early sustained remission, can provide tapering and stopping disease-modifying antirheumatic drugs (DMARDs). With new treatment strategies drug-free sustained remission is becoming an achievable goal. Sustained remission is associated with improved outcomes in regard to function, patient-reported outcomes and survival. Drug-free sustained remission is characterized by normalized function ability and survival. Sustained remission and, in particular, drug-free sustained remission offer hope that early identification of patients with arthritis, early improved novel treatments and treatment with target to achieve remission may potentially transform the progressive course of RA disease and disrupt RA chronicity. In this review we summarize the recent evidence on sustained remission in patients with RA, treatment strategies to achieve sustained remission, management of patients in sustained remission and significance of sustained remission from the patient perspective.

Abstract
INTRODUCTION The first biosimilar infliximab, CT-P13 infliximab-dyyb was approved in 2013 by the European Medicines Agency (EMA) and in 2016 by the United States Food and Drug Administration (FDA) and has been used for the treatment of rheumatoid arthritis (RA) for 4 years. Areas covered: CT-P13 with the three brand names on the market has highly similar efficacy and safety profiles but lower price than originator infliximab and are approved in more than 80 countries. One of the most important determinants of the implementation of CT-P13 in the treatment of RA is scientific evidence from clinical studies and real-world pharmacovigilance data. Here, we review all available clinical data supporting the similarity of CT-P13 to originator infliximab in its clinical efficacy and safety for the treatment of RA and related arthritis. In addition, we consider the role of CT-P13 in therapeutic strategies for RA treatment. Expert commentary: With its highly similar efficacy and safety profile to originator infliximab and its lower price, CT-P13 is expected to be very useful in RA treatment, whether it is applied earlier or switched from originator infliximab or other biologics. Future educational initiatives will be important to overcome misunderstandings about biosimilars and to improve the implementation of CT-P13.

Abstract
Monoclonal antibody therapeutics have been approved for over 30 targets and diseases, most commonly cancer. Antibodies have become the new backbone of the pharmaceutical industry, which previously relied on small molecules. Compared with small molecules, monoclonal antibodies (mAbs) have exquisite target selectivity and hence less toxicity as a result of binding other targets. The clinical value of both mAbs and ligand traps has been proven. New applications of mAbs are being tested and mAbs have now been designed to target two (bi-specific, eg TNF-α and IL-17) or more targets simultaneously, augmenting their therapeutic potential. Because of space limitations and the wide ranging scope of this review there are regrettably, but inevitably, omissions and missing citations. We have chosen to highlight the first successes in inflammatory diseases and cancer, but a broader overview of approved mAbs and related molecules can be found in Table 1.

Abstract
Although infliximab is approved for psoriasis, its efficacy is reduced over time in some patients. The aim of this phase III trial is to evaluate efficacy and safety of infliximab dose escalation in Japanese psoriasis patients with loss of efficacy to standard‐dose therapy. Patients with plaque psoriasis, psoriatic arthritis, pustular psoriasis or psoriatic erythroderma who showed loss of efficacy to standard‐dose therapy received infliximab dose escalation (10 mg/kg every 8 weeks) from weeks 0 to 32. Loss of efficacy was defined as not maintaining 50% reduction in the Psoriasis Area and Severity Index (PASI 50) after achieving PASI 75. Efficacy and safety were evaluated up to week 40. Fifty‐one patients received dose escalation and 43 completed the study. PASI 75 and median improvement rate of PASI score at week 40 were 44% and 70.0%, respectively, showing efficacy in skin symptoms. Efficacies in quality of life, nail psoriasis and joint pain were also obtained. Median serum infliximab level increased from less than 0.1 to 1.1 μg/mL from weeks 0 to 40, showing positive correlation between efficacy and serum infliximab level at week 40. Favorable efficacy was observed in patients with detectable serum infliximab levels (≥0.1 μg/mL) at baseline. Incidences of adverse events, serious adverse events, serious infections and serious infusion reactions were 92%, 10%, 4% and 0%, respectively. No marked difference was observed in both efficacy and safety among psoriasis types. No new safety concerns were observed. Infliximab dose escalation was effective and well‐tolerated in psoriasis patients with loss of efficacy to standard‐dose therapy, suggesting that dose escalation may be a useful therapeutic option for these patients.

RMD Open 2016; 2:e000323.

Abstract
Objective To determine whether an induction-maintenance strategy of combined therapy (methotrexate (MTX)+tumour necrosis factor (TNF) inhibitor (TNFi)) followed by withdrawal of TNFi could yield better long-term results than a strategy with MTX monotherapy, since it is unclear if the benefits from an induction phase with combined therapy are sustained if TNFi is withdrawn. Methods We performed a meta-analysis of trials using the initial combination of MTX+TNFi in conventional synthetic disease-modifying antirheumatic drug-naïve patients with early rheumatoid arthritis (RA). A systematic literature search was performed for induction-maintenance randomised controlled trials (RCTs) where initial combination therapy was compared with MTX monotherapy in patients with clinically active early RA. Our primary outcome was the proportion of patients who achieved low disease activity (LDA; Disease Activity Score (DAS)28<3.2) and/or remission (DAS28<2.6) at 12–76 weeks of follow-up. A random-effects model was used to pool the risk ratio (RR) for LDA and remission and heterogeneity was explored by subgroup analyses. Results We identified 6 published RCTs, 4 of them where MTX+adalimumab was given as initial therapy and where adalimumab was withdrawn in a subset of patients after LDA/remission had been achieved. 2 additional trials used MTX+infliximab as combination therapy. The pooled RRs for achieving LDA and clinical remission at follow-up after withdrawal of TNFi were 1.41 (95% CI 1.05 to 1.89) and 1.34 (95% CI 0.95 to 1.89), respectively. There was significant heterogeneity between trials due to different treatment strategies, which was a limitation to this study. Conclusions Initial therapy with MTX+TNFi is associated with a higher chance of retaining LDA and/or remission even after discontinuation of TNFi.

Abstract
Rheumatoid arthritis (RA) is the most common inflammatory rheumatic disease. It leads to irreversible joint damage, physical handicap, and reduced life expectancy. The past two decades have seen considerable therapeutic advances with the development of biologic treatments to block proinflammatory cytokines or modulate lymphocyte function, followed by the development of small molecules to target intracellular signaling. Nevertheless, only a minority of patients can achieve disease remission, especially long term, warranting further investigation into newer therapeutic options. Targeting single proinflammatory pathways may not be sufficient, as suggested by variable results with T helper (Th)-17-related cytokine blockade. Multilevel information from 'omics' techniques along with data from mechanistic studies might facilitate the identification of pivotal checkpoints in RA disease pathogenesis and the subsequent development of new effective treatments.

Abstract
The aim of this study was to investigate remission and biologic-free remission after orthopaedic surgery and related clinical factors in non-responder to infliximab for rheumatoid arthritis (RA). We analyzed 74 patients who were treated with 3 mg/kg infliximab and methotrexate and underwent orthopaedic surgery after non-responder to infliximab with disease activity score (DAS) 28 (CRP) of ≥3.2. The rates of remission and biologic-free remission at 52 weeks after orthopaedic surgery were investigated and the clinical factors related to remission and biologic-free remission were analyzed by logistic regression and receiver-operating characteristic analyses. The rates of total remission and biologic-free remission were 37/74 (50 %) and 9/74 (12.2 %), respectively. Regarding orthopaedic surgery, the rates of remission and biologic-free remission were 25/38 (65.8 %) and 7/38 (18.4 %) for synovectomy, 7/20 (35 %) and 0/20 (0 %) for arthroplasty, and 5/16 (31.3 %) and 2/16 12.5) for others including spine surgery and foot surgery. DAS28(CRP) at baseline was significantly related to both remission and biologic-free remission. Prednisolone was negatively associated with remission, and DAS28(CRP) was related to biologic-free remission by logistic regression analyses. DAS28(CRP) below 3.7 was cutoff point for acquiring biologic-free remission of non-responder to infliximab after orthopaedic surgery. Therefore orthopaedic surgery may be effective to obtain remission or biologic-free remission in RA patients treated with biologics.

Abstract
The advent of new medications and new treatment strategies for rheumatoid arthritis has made it possible to achieve remission in more patients than before. Furthermore, recent clinical trials and register studies suggest that some patients who initially required aggressive therapy may achieve biologic-free remission or even the ultimate goal of therapy, drug-free remission, resembling recovery. Here, we present a discursive review of the most important studies addressing these issues. Based on the overall results, it remains unclear if achieving biologic-free and drug-free remissions are primarily due to the natural course of the disease or to the early therapeutic intervention according to the 'window of opportunity' hypothesis. Although medication-free remission is only achievable in a small subset of patients, characterizing this patient cohort may provide important information about beneficial prognostic factors and the underlying mechanisms. In summary, in a subset of patients biologic-free and even drug-free remission can be achieved; pursuing these possibilities in practice may decrease the risk for long-term side effects and attenuate the economic burden of the disease.

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 sometimes intense, persistent and disabling pain associated with rheumatoid arthritis (RA) and spondyloarthritis frequently has a multifactorial, simultaneously central and peripheral origin, and it may be due to currently active inflammation or joint damage and tissue destruction caused by a previous inflammatory condition. The symptoms of inflammatory pain symptoms can be partially relieved by non-steroidal anti-inflammatory drugs, but many patients continue to experience moderate pain due to alterations in central pain regulation mechanisms, as in the case of the chronic widespread pain (CWP) characterising fibromyalgia. The importance of distinguishing CWP from inflammatory pain is underlined by the fact that drugs such as tumour necrosis factor inhibitors are expensive, and direct costs are higher in patients with concomitant CWP than in those without. The management of pain requires a combination approach that includes pharmacological analgesia, and biological and non-biological treatments because, although joint replacement surgery can significantly improve RA-related pain, it may only be available to patients with the most severe advanced disease.

Abstract
OBJECTIVE To investigate the probability of clinical remission (REM) or low disease activity (LDA) after 1 year of infliximab (IFX) therapy based on disease activity at 3 months in patients with rheumatoid arthritis (RA). METHODS Methotrexate-refractory patients with RA received 3 mg/kg of IFX at weeks 0, 2, and 6, followed by 3 mg/kg, 6 mg/kg, or 10 mg/kg every 8 weeks from Week 14 (W14) to Week 46. Correlation of disease activity at W14 with disease activity at W54 and probability of REM/LDA at W54 were analyzed in each dosing group. RESULTS Disease activities at W14 were significantly correlated with both disease activity at W54 and probability of REM/LDA at W54 in patients continuing 3 mg/kg as well as in those receiving 6 mg/kg or 10 mg/kg therapy from W14. Results showed that, if approximate REM or LDA had not been achieved by W14, > 50% of patients continuing 3 mg/kg therapy would not be able to achieve REM or LDA at W54. However, even in patients with high or moderate disease activity at W14, dose escalation to 6 mg/kg or 10 mg/kg enabled many to achieve REM/LDA. CONCLUSION Disease activity at W14 in standard-dose IFX therapy enabled the prediction of longterm clinical response at continued standard dose, as well as subsequent escalated-dose regimens. Disease activity at W14 was hypothesized to be an important index for IFX treatment strategy.

Abstract
OBJECTIVE The study objective was to evaluate and update the safety data from randomized controlled trials of tumor necrosis factor inhibitors in patients treated for rheumatoid arthritis. METHODS A systematic literature search was conducted from 1990 to May 2013. All studies included were randomized, double-blind, controlled trials of patients with rheumatoid arthritis that evaluated adalimumab, certolizumab pegol, etanercept, golimumab, or infliximab treatment. The serious adverse events and discontinuation rates were abstracted, and risk estimates were calculated by Peto odds ratios (ORs). RESULTS Forty-four randomized controlled trials involving 11,700 subjects receiving tumor necrosis factor inhibitors and 5901 subjects receiving placebo or traditional disease-modifying antirheumatic drugs were included. Tumor necrosis factor inhibitor treatment as a group was associated with a higher risk of serious infection (OR, 1.42; 95% confidence interval [CI], 1.13-1.78) and treatment discontinuation due to adverse events (OR, 1.23; 95% CI, 1.06-1.43) compared with placebo and traditional disease-modifying antirheumatic drug treatments. Specifically, patients taking adalimumab, certolizumab pegol, and infliximab had an increased risk of serious infection (OR, 1.69, 1.98, and 1.63, respectively) and showed an increased risk of discontinuation due to adverse events (OR, 1.38, 1.67, and 2.04, respectively). In contrast, patients taking etanercept had a decreased risk of discontinuation due to adverse events (OR, 0.72; 95% CI, 0.55-0.93). Although ORs for malignancy varied across the different tumor necrosis factor inhibitors, none reached statistical significance. CONCLUSIONS These meta-analysis updates of the comparative safety of tumor necrosis factor inhibitors suggest a higher risk of serious infection associated with adalimumab, certolizumab pegol, and infliximab, which seems to contribute to higher rates of discontinuation. In contrast, etanercept use showed a lower rate of discontinuation. These data may help guide clinical comparative decision making in the management of rheumatoid arthritis.

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
To date, the significance of early intervention with methotrexate and biological disease-modifying anti-rheumatic drugs for rheumatoid arthritis (RA) has not been realized. Longitudinal safety and cost have arisen as new concerns. The concept of a treatment holiday, drug discontinuation after achieving remission, may solve these problems. The authors performed a systematic literature review and identified 13 reports from 10 studies (TNF20, BeSt, OPITMA, HIT-HARD, IMPROVED, PRIZE, IDEA, EMPIRE, tREACH and AVERT) for early RA (≤2 years). Eight out of 13 reports (61.5%) were published in 2013 or 2014, indicating emerging interest in recent years. Also, the authors performed a sub-analysis of the HONOR study (n = 51) to compare early (≤2 years) and established RA. The proportions of remission (REM) and low disease activity were higher in early RA (REM: 63.0 vs 33.3%, p = 0.0346; low disease activity: 77.8 vs 45.8%, p = 0.0185). In conclusion, early intervention is beneficial for successful treatment holiday, which may lead to risk and cost reduction. However, further investigation is required.

Abstract
While for a century therapeutics has been dominated by small molecules, i.e. organic chemicals of ~400Da absorbable via the gut, this is no longer the case. There are now a plethora of important medicines which are proteins and injectable, which have dramatically improved the therapy of many inflammatory diseases and of cancer. Most of these are monoclonal antibodies, some are receptor Ig Fc fusion proteins, others are cytokines or enzymes. The key to this new aspect of therapeutics has been the filling of unmet needs, and the consequent commercial success, which promoted further research and development. The first 'biologic' for a common disease, rheumatoid arthritis (RA), was a monoclonal antibody, infliximab, to human tumour necrosis factor (TNF). This was based on our work, which is described in this review, summarizing how TNF was defined as a good target in RA, how it was developed is described here, as well as future indications for anti-TNF and related agents. Biologics are now the fastest growing sector of therapeutics.

Abstract
BACKGROUND We assessed the effects of reduction and withdrawal of treatment in patients with rheumatoid arthritis who had a remission while receiving etanercept-plus-methotrexate therapy. METHODS Patients with early active disease who had not previously received methotrexate or biologic therapy received 50 mg of etanercept plus methotrexate weekly for 52 weeks (open-label phase). We then randomly assigned patients who had qualifying responses at weeks 39 and 52 to receive 25 mg of etanercept plus methotrexate (combination-therapy group), methotrexate alone, or placebo for 39 weeks (double-blind phase). Patients who had qualifying responses at week 39 of the double-blind phase had all treatment withdrawn at that time and were followed to week 65 (treatment-withdrawal phase). The primary end point was the proportion of patients with sustained remission in the double-blind phase. RESULTS Of 306 patients enrolled, 193 underwent randomization in the double-blind phase; 131 qualified for the treatment-withdrawal phase. More patients in the combination-therapy group than in the methotrexate-alone group or the placebo group met the criterion for the primary end point (40 of 63 [63%] vs. 26 of 65 [40%] and 15 of 65 [23%], respectively; P=0.009 for combination therapy vs. methotrexate alone; P<0.001 for combination therapy vs. placebo). At 65 weeks, 28 patients (44%) who had received combination therapy, 19 (29%) who had received methotrexate alone, and 15 (23%) who had received placebo were in remission (P=0.10 for combination therapy vs. methotrexate alone; P=0.02 for combination therapy vs. placebo; P=0.55 for methotrexate alone vs. placebo). No significant between-group differences were observed in radiographic progression of disease. Serious adverse events were reported in 3 patients (5%) in the combination-therapy group, 2 (3%) in the methotrexate-alone group, and 2 (3%) in the placebo group. CONCLUSIONS In patients with early rheumatoid arthritis who had a remission while receiving full-dose etanercept-plus-methotrexate therapy, continuing combination therapy at a reduced dose resulted in better disease control than switching to methotrexate alone or placebo, but no significant difference was observed in radiographic progression.

Abstract
BACKGROUND Anti-tumor necrosis factor (TNF) agents are effective in treating patients with rheumatoid arthritis (RA), but they are associated with (dose-dependent) adverse effects and high costs. To prevent overtreatment, several trials have assessed the effectiveness of down-titration compared with continuation of the standard dose. OBJECTIVES To evaluate the benefits and harms of down-titration (dose reduction, discontinuation or disease activity guided dose tapering) of anti-TNF agents (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab) on disease activity, functioning, costs, safety and radiographic damage compared with usual care in patients with RA and low disease activity. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Issue 8, 2013; Ovid MEDLINE (1946 to 8 September 2013); EMBASE (1947 to 8 September 2013); Science Citation Index (Web of Science); and conference proceedings of the American College of Rheumatology (2005 to 2012) and European League against Rheumatism (2005 to 2013). We contacted authors of the seven included studies to ask for additional information on their study; five responded. SELECTION CRITERIA Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing down-titration (dose reduction, discontinuation, disease activity-guided dose tapering) of anti-TNF agents (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab) to usual care/no down-titration in patients with RA and a low disease activity state. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risk of bias and extracted data. MAIN RESULTS Six RCTs and one CCT (total 1203 participants), reporting anti-TNF down-titration, were included. Three studies (559 participants) reported anti-TNF dose reduction compared with anti-TNF continuation. Five studies (732 participants) reported anti-TNF discontinuation compared with anti-TNF continuation (two studies assessed both anti-TNF discontinuation and dose reduction), and one study assessed disease activity-guided anti-TNF dose tapering (137 participants). These studies include only adalimumab and etanercept; controlled data on other anti-TNF agents are absent. Two studies were available in full text; one was assessed as having low risk of bias and the other high risk. Five studies were available only as one or more abstracts. Because data provided in these abstracts were limited, risk of bias was unclear. Clinical heterogeneity between the trials was high.Dose reduction of anti-TNF (etanercept data only) showed no statistically significant or clinical relevant difference in disease activity score in 28 joints (DAS28) (mean difference (MD) 0.10, 95% confidence interval (CI) -0.11 to 0.31) (scale 0.9 to 8; higher score indicates worse disease activity). The proportion of participants who maintained low disease activity was slightly lower among participants given reduced doses of the anti-TNF agent (risk ratio (RR) 0.87, 95% CI 0.78 to 0.98, absolute risk difference (ARD) 9%). Radiographic outcome was slightly worse, but this was not clinically meaningful, compared with continuation of anti-TNF (MD 0.11, 95% CI 0.08 to 0.14) (scale 0 to 448; higher score indicates greater joint damage). Function was not statistically different between anti-TNF dose reduction and continuation (MD 0.10, 95% CI 0.00 to 0.20) (scale 0 to 3; higher score indicates worse functioning). Reinstalment of anti-TNF after failure of dose reduction showed a 5% risk of persistent flare. Data on numbers of serious adverse events (SAEs) (RR 0.58, 95% CI 0.23 to 1.45, ARD -2%) and withdrawals due to adverse events (AEs) (RR 0.57, 95% CI 0.17 to 1,92, ARD -1%) were inconclusive. Most outcomes were based on moderate quality evidence.Participants who discontinued anti-TNF (adalimumab and etanercept data) had higher mean DAS28 (DAS28-erythrocyte sedimentation rate (ESR): MD 1.10, 95% CI 0.86 to 1.34) and DAS28-C-reactive protein (CRP): MD 0.57 95% CI -0.09 to 1.23) and were less likely to maintain a low disease activity state (RR 0.43, 95% CI 0.27 to 0.68, ARD 40%). Also, radiographic and functional outcomes are worse after anti-TNF discontinuation (MD 0.66, 95% CI 0.63 to 0.69, and MD 0.30, 95% CI 0.19 to 0.41, respectively). Data on numbers of SAEs (RR 1.26, 95% CI 0.61 to 2.63, ARD 2%) and withdrawals due to AEs (RR 0.72, 95% CI 0.23 to 2.24, ARD -1%) were inconclusive. Most outcomes were based on moderate quality evidence.The one study comparing disease activity-guided anti-TNF dose tapering (adalimumab and etanercept data) reported no statistically significant differences in functional outcomes (MD 0.20, 95% CI -0.02 to 0.42). Significantly higher mean disease activity was found among participants with tapered anti-TNF at study end (MD 0.50, 95% CI 0.11 to 0.89). No full text of this trial was available for this review. No other major outcomes were reported. All outcomes were based on low quality evidence. AUTHORS' CONCLUSIONS We can conclude, mostly based on moderate quality evidence, that non-disease activity guided dose reduction of etanercept 50 mg weekly to 25 mg weekly, after at least three to 12 months of low disease activity, seems as effective as continuing the standard dose with respect to disease activity and functional outcomes, although dose reduction significantly induces minimal and not clinically meaningful differences in radiological progression. Discontinuation (also without disease activity-guided adaptation) of adalimumab and etanercept is inferior to continuation of treatment with respect to disease activity and radiological outcomes and function. Disease activity-guided dose tapering of adalimumab and etanercept seems slightly inferior to continuation of treatment with respect to disease activity, with no difference in function. However the only study investigating this comparison included lower than projected numbers of participants.Caveats of this review are that available data are limited. Also, the heterogeneity between studies and the suboptimal design choices (including absence of disease activity-guided dose reduction and discontinuation and use of superiority designs) limit definitive conclusions. None of the included studies assessed long-term safety and costs, although these factors are specific reasons why clinicians consider lowering the dose or stopping the administration of anti-TNF agents.Future research should include other anti-TNF agents; assessment of disease activity, function and radiographic outcomes after longer follow-up; and assessment of long-term safety, cost-effectiveness and predictors for successful down-titration. Also use of a validated flare criterion, non-inferiority designs and disease activity-guided instead of fixed-dose tapering or stopping would allow researchers to better interpret study findings and generalise the information to clinical practice.

Abstract
BACKGROUND AND OBJECTIVES This study is to evaluate the outcome of cataract surgery in patients with refractory uveitis associated with Behçet disease (BD) treated with infliximab. DESIGN AND SETTINGS A retrospective study in a university-based tertiary referral center in the period between July 2003 and November 2011. METHODS This is a retrospective study of patients with refractory uveitis associated with BD who underwent phacoemulsification cataract surgery under systemic infliximab therapy between July 2003 and November 2011 at King Abdulaziz University Hospital, Riyadh, Saudi Arabia. RESULTS Six patients (9 eyes), 5 of which were male and 1 female, were identified in this study. The mean (SD) age and follow-up period were 26.2 (6.6) years (range, 16-36 years) and 51.6 (28.8) months (range, 12.84 months), respectively. All the patients underwent phacoemulsification with intraocular lens implantation. Postoperatively, visual acuity improved in all eyes and was 20/40 or better in 7 eyes (77.8%). In the immediate postoperative period, anterior chamber inflammation ranged from 2+ to 3+ cells. None of the patients developed inflammation relapse postoperatively. The most common postoperative complication was posterior capsular opacification in 5 eyes (55%), 4 of which were managed with neodymium:yttrium-aluminum garnet laser capsulotomy. Three eyes had glaucoma, 2 of which underwent successful glaucoma surgery and one was managed with topical antiglaucoma medications. CONCLUSION In patients with refractory uveitis associated with BD who are treated with infliximab, cataract surgery is safe and has a good prognosis.

Abstract
Despite considerable advances in the management of rheumatoid arthritis, results are still not satisfactory for all patients. The treatment goal in rheumatoid arthritis is remission, and there currently are numerous conventional and biological medications available to reach this aim. There are also different treatment strategies but with only limited comparative evidence about their efficacies. More patients now achieve remission while on treatment, but it remains elusive in the majority of patients. Treatment-free remission, the ultimate goal of therapy, is only achieved in very few patients; even when this happens, it is most likely due to the natural course of the disease rather than to any specific therapies. Modern treatment is based on the initiation of aggressive therapy as soon as the diagnosis is established, and on modifying or intensifying therapy guided by frequent assessment of disease activity. In this commentary we will discuss the current treatment paradigm as well as the possibility of an induction-maintenance regimen with biological disease-modifying antirheumatic drugs in early rheumatoid arthritis.

Abstract
BACKGROUND Biologic agents targeting tumor necrosis factor (TNF) have revolutionized the treatment of rheumatoid arthritis (RA). Clinical remission is perceived as a realistic primary goal, and its maintenance leads to structural and functional remission. OBJECTIVE This study reviews whether discontinuation of biologic agents is possible after sustained remission and discusses its significance from the risk/benefit point of view (including safety and health economic considerations). METHODS Using a strategic PubMed search, 45 original research articles regarding discontinuation of biologic agents were identified; 7 were selected that had an obvious focus on discontinuation of biologic agents. These articles included the TNF20, BeSt (Behandel Strategieen), and RRR (Remission Induction by Remicade in RA) studies. However, because of the limitations of the original search, we also review here some articles that did not focus mainly on discontinuation of biologic agents but that presented data regarding biologic-free control. These studies included OPTIMA (Optimal Protocol for Treatment Initiation With MTX and Adalimumab), PRESERVE, and CERTAIN, as well as some recent findings in the HONOR (Humira Discontinuation Without Functional and Radiographic Damage Progression Following Sustained Remission) study from our department. RESULTS In BeSt and OPTIMA, clinical remission was sustained without functional progression by discontinuing TNF inhibitors, after reducing disease activity by using TNF inhibitors and methotrexate (MTX), in patients with early RA and who were MTX naive. In some studies (including RRR and HONOR), the discontinuation of TNF inhibitors after sustained remission was possible in some patients with long-standing RA who had an inadequate response to MTX. When disease activity flared up after treatment discontinuation, re-treatment with infliximab or adalimumab was highly effective and safe in the majority of patients. It is also clear that tight control with TNF inhibitors and MTX seems to be a prerequisite for having a better chance of biologic-free remission. CONCLUSIONS Intensive treatment with TNF inhibitors may change the disease process of RA and potentially offers the possibility of a "treatment holiday" from biologic agents.

Abstract
Background Preliminary, mostly uncontrolled studies suggest that dose reduction or discontinuation of tumour necrosis factor blockers can be achieved in a relevant proportion of patients with RA without loss of disease control. However, long term safety, cost effectiveness and feasibility in clinical practice remain uncertain. Methods/Design This study is a 18-months pragmatic, non-inferiority, cost minimalisation, randomized controlled trial on dose reduction and discontinuation of the subcutaneous tumour necrosis factor (TNF) blockers adalimumab and etanercept in RA patients with low disease activity. 180 RA patients with low disease activity (DAS28 < 3.2 or clinical judgment of the rheumatologist) are randomized 2:1 to either increased spacing and eventually discontinuation after 6 months of the TNF blocker, and usual care. Implementation is done in routine daily care, using treat to target and feedback implementation in both treatment arms. The primary outcome is non-inferiority (NI margin 20%) in cumulative incidence of persistent (> 3 months) RA flare, according to a recently validated DAS28 based flare criterion (DAS28 change > 1.2, or DAS28 increase of 0.6 and current DAS28 ≥ 3.2). Secondary outcomes include mean disease activity, function, radiographic progression, safety and cost effectiveness. Cost per quality adjusted life year (QALY) differences between groups are expressed as a decremental cost effectiveness ratio (DCER), i.e. saved costs divided by (possible) loss in QALY. Discussion The design of this study targeted several clinical and methodological issues on TNF blocker dose de-escalation, including how to taper the TNF blockers, the satisfactory control condition, how to define flare, implementation in clinical practice, and the choice of the non-inferiority margin. Pragmatic cost minimalisation studies using non-inferiority designs and DCERs will become more mainstream as cost effectiveness in healthcare gains importance.

Abstract
OBJECTIVE To investigate possible predictors for lack of pain improvement after 1 year of treatment for early rheumatoid arthritis (RA). METHODS The Early Rheumatoid Arthritis Network (ERAN) database was used for analysis of baseline and 1-year pain data. The ERAN is a hospital-based inception cohort of 1,189 people. Short Form 36 questionnaire bodily pain scores were used to calculate change in pain at 1 year as the outcome. The proportion of the Disease Activity Score in 28 joints (DAS28) attributable to patient-reported components (joint tenderness and visual analog scale score; DAS28-P) at baseline was derived as a predictor. Predictors of less improvement in pain were investigated using adjusted odds ratios (OR(adj) ) generated by logistic regression, adjusting for 14 additional clinical and demographic covariates. RESULTS Greater pain at baseline was associated with sex, high DAS28, worse mental health, and smoking. Most patients with early RA reported incomplete improvement in bodily pain after 1 year. The DAS28-P index did not significantly change in the patients whose disease remained active. Less improvement in pain was predicted by female sex (OR(adj) 3.41, 95% confidence interval [95% CI] 1.35-8.64) and a high DAS28-P index at baseline (OR(adj) for tertiles 2.09, 95% CI 1.24-3.55). Other conventional RA risk factors did not predict pain changes. CONCLUSION The factors most likely to predict less improvement in pain in early RA are female sex and a high DAS28-P index. A high DAS28-P index may reflect greater contributions of noninflammatory factors, such as central sensitization, to pain. Strategies in addition to inflammatory disease suppression may be required to adequately treat pain.

Abstract
PURPOSE OF REVIEW Biologics targeting tumor necrosis factor (TNF) has revolutionized the treatment of rheumatoid arthritis (RA) and clinical remission becomes a realistic treatment goal. After achieving remission, discontinuation of TNF inhibitors may become an important issue from viewing points of safety and economy. However, there is not well established firm evidence regarding biologic-free remission. We here document whether 'treatment holiday' of TNF inhibitors is possible in RA patients, after maintaining low disease activity by intensive treatment with TNF inhibitors. RECENT FINDINGS From European studies such as BeSt and OPTIMA in patients with early RA and Japanese studies such as RRR and HONOR in patients with established RA, after reduction of disease activity to clinical remission or low disease activity in patients with RA by infliximab or adalimumab in combination with methotrexate, some patients could successfully remain in clinical remission without TNF inhibitors for 6 months or 1 year and without radiologic and functional progression of articular destruction. SUMMARY After maintaining low disease activity by intensive treatment with TNF inhibitors, discontinuation of TNF inhibitors without disease flare, joint damage progression and functional impairment, treatment holiday, is possible in some RA patients.

Abstract
INTRODUCTION To determine the validity and reliability of patients' self-performed joint counts compared to joint counts by professional assessors in rheumatoid arthritis (RA) patients in different disease activity states. METHODS In patients with established RA we determined the inter-rater reliability of joint counts performed by an independent evaluator and the patient using intraclass correlation (ICC), and agreement on activity in individual joints by kappa statistics. We also performed longitudinal analyses to assess consistency of assessments over time. Finally, we investigated the concordance of joint counts of different assessors in patients with different levels of disease activity. RESULTS The reliability of patient self-performed joint counts was high when compared to independent objective assessment (ICC; 95%confidence interval (CI)) for the assessment of swelling (0.32; 0.15 to 0.46) and tenderness (0.75; 0.66 to 0.81), with higher agreement for larger joints (kappa: 0.57 and 0.45, respectively) compared to smaller joints (metacarpo-phalangeal joint (MCPs): 0.31 and 0.45; and proximal interphalangeal joint (PIPs): 0.22 and 0.47, for swelling and tenderness, respectively).Patients in remission according to the Simplified Disease Activity Index (SDAI ≤ 3.3) showed better concordance of the joint counts (swollen joint count (SJC) ties 25/37, tender joint count (TJC) ties 26/37) compared to moderate/high disease activity states (SDAI > 11; MDA/HDA: SJC ties 9/72, TJC ties 21/72). Positive and negative predictive values regarding the presence of SDAI remission were reasonably good (0.86 and 0.95, respectively). A separate training session for patients did not improve the reliability of joint assessment. The results were consistent in the longitudinal analyses. CONCLUSIONS Self-performed joint counts are particularly useful for monitoring in patients having attained remission, as these patients seem able to detect state of remission.

Discontinuation of adalimumab treatment in rheumatoid arthritis patients after achieving low disease activity. Mod Rheumatol 2012; 22:814-22. [PMID: 22270346 DOI: 10.1007/s10165-011-0586-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2011] [Accepted: 12/22/2011] [Indexed: 10/14/2022]
Abstract
OBJECTIVE We implemented a retrospective study to explore discontinuation of therapy with adalimumab (ADA) without exacerbation in rheumatoid arthritis (RA) patients who had achieved low disease activity (LDA) with the biological agent. METHODS We enrolled 46 RA patients who had completed open extension of a double-blind, placebo-controlled trial of ADA monotherapy in Japan and who had LDA (DAS28-CRP <2.7) at the last administration of ADA in the extension trials; this date was defined as week 0 in the present study. Treatment of RA was at the discretion of the attending physician after week 0. The primary endpoint of this study was the percentage of patients who maintained discontinuation of biological agents and LDA for 52 weeks. RESULTS Twenty-four of the enrolled patients continued ADA while the rest discontinued ADA after the administration of the drug at week 0. Fourteen of the 22 patients did not restart biological agents, and 4 (18.2%) of these maintained LDA through week 52. All 4 of these patients had received ADA monotherapy before week 0. CONCLUSION Some RA patients who have achieved LDA with ADA monotherapy can discontinue the biologic without incurring increased disease activity. A prospective randomized study is required to confirm the results of our study.

Systematic review and meta-analysis of the efficacy and safety of existing TNF blocking agents in treatment of rheumatoid arthritis. PLoS One 2012; 7:e30275.

Abstract
Background and Objectives Five-tumour necrosis factor (TNF)-blockers (infliximab, etanercept, adalimumab, certolizumab pegol and golimumab) are available for treatment of rheumatoid arthritis. Only few clinical trials compare one TNF-blocker to another. Hence, a systematic review is required to indirectly compare the substances. The aim of our study is to estimate the efficacy and the safety of TNF-blockers in the treatment of rheumatoid arthritis (RA) and indirectly compare all five currently available blockers by combining the results from included randomized clinical trials (RCT). Methods A systematic literature review was conducted using databases including: MEDLINE, SCOPUS (including EMBASE), Cochrane library and electronic search alerts. Only articles reporting double-blind RCTs of TNF-blockers vs. placebo, with or without concomitant methotrexate (MTX), in treatment of RA were selected. Data collected were information of patients, interventions, controls, outcomes, study methods and eventual sources of bias. Results Forty-one articles reporting on 26 RCTs were included in the systematic review and meta-analysis. Five RCTs studied infliximab, seven etanercept, eight adalimumab, three golimumab and three certolizumab. TNF-blockers were more efficacious than placebo at all time points but were comparable to MTX. TNF-blocker and MTX combination was superior to either MTX or TNF-blocker alone. Increasing doses did not improve the efficacy. TNF-blockers were relatively safe compared to either MTX or placebo. Conclusions No single substance clearly rose above others in efficacy, but the results of the safety analyses suggest that etanercept might be the safest alternative. Interestingly, MTX performs nearly identically considering both efficacy and safety aspects with a margin of costs.

Abstract
We aimed to investigate whether delayed treatment with tumor necrosis factor (TNF) inhibitors in incomplete responders to synthetic disease-modifying anti-rheumatic drugs (DMARDs) was effective among patients with very early rheumatoid arthritis (RA) with poor prognosis factors. We examined 22 patients with very early RA who were positive for anti-cyclic citrullinated peptide antibodies or IgM-rheumatoid factor. The mean disease duration at entry was 14.1 weeks. A treat-to-target strategy, aiming at simplified disease activity index (SDAI) remission, was initiated with synthetic DMARDs. SDAI remission was not achieved in 9 of the 22 patients with synthetic DMARDs alone, and TNF inhibitors were added in these patients. SDAI values in these 9 patients were further examined for the following 6 months. The TNF inhibitors (infliximab 8, etanercept 1) were added at a mean interval of 34.1 weeks after the initiation of synthetic DMARDs. SDAI remission was achieved in 4 of the 9 patients (44.4%) at 3 months and in 8 of the 9 patients (88.9%) at 6 months after the introduction of the TNF inhibitors. Radiographic damage had not progressed in these patients. Delayed treatment with TNF inhibitors is effective and tolerable for patients with very early RA with poor prognosis factors.

Abstract
Rheumatoid arthritis (RA), ankylosing spondylitis (AS) and psoriatic arthritis (PsA) are immune-mediated conditions that share an inflammatory mechanism fuelled by excessive cytokines, particularly TNF. Control of inflammation and rapid suppression of cytokines are important in treating these diseases. With this understanding and the corresponding advent of TNF inhibitors, RA patients, AS patients and PsA patients have found more choices than ever before and have greater hope of sustained relief. As a widely used TNF inhibitor, infliximab has a deep and established record of efficacy and safety data. Extensive evidence - from randomised controlled clinical trials, large registries and postmarketing surveillance studies - shows that infliximab effectively treats the signs and symptoms, provides rapid and prolonged suppression of inflammation, prevents radiologically observable disease progression and offers an acceptable safety profile in RA, AS and PsA. In very recent studies, investigators have observed drug-free remission in some patients. Additionally, infliximab may interfere with rapidly progressing disease in RA by early addition to methotrexate in patients with signs of an aggressive course. Finally, infliximab has been shown to reduce PsA clinical manifestations such as nail involvement. With our current understanding, substantial data and increasing confidence regarding use in practice, infliximab can be considered a well-known drug in our continued campaign against inflammatory rheumatic diseases.

Abstract
Treatment strategies for rheumatoid arthritis (RA) will continue to evolve as new drugs are developed, as new data become available, and as our potential to achieve greater and more consistent outcomes becomes more routine. Many patients will find both symptom relief and modest control of their disease with disease-modifying antirheumatic drugs (DMARDs), yet this course of therapy is clearly not effective in all patients. In fact, despite strong evidence that intensive treatment in the early stages of RA can slow or stop disease progression and may prevent disability, many patients continue to be managed in a stepwise manner and are treated with an ongoing monotherapy regimen with DMARDs. There is now a large body of evidence demonstrating the success of treating RA patients with anti-TNF therapy, usually in combination with methotrexate. As a result of the increased use of anti-TNF therapy, treatment paradigms have changed - and our practice is beginning to reflect this change. In the present review, we summarize the salient points of several recently proposed and emerging treatment paradigms with an emphasis on how these strategies may impact future practice.

Baseline tumour necrosis factor alpha levels predict the necessity for dose escalation of infliximab therapy in patients with rheumatoid arthritis. Ann Rheum Dis 2011; 70:1208-15.

Abstract
OBJECTIVES To investigate the possible role of baseline plasma tumour necrosis factor alpha levels (baseline-TNF) on the clinical response to infliximab in patients with rheumatoid arthritis (RA). METHODS Patients with RA refractory to methotrexate received 3, 6, or 10 mg/kg of infliximab every 8 weeks, in a randomised, double-blind manner: the RISING study. Clinical response (disease activity score in 28 joints based on C-reactive protein or American College of Rheumatology core set) at week 54 and serum infliximab levels were compared in three patient groups with low, intermediate, or high baseline-TNF (TNF-low, TNF-int, or TNF-high). RESULTS In TNF-low patients, the clinical response to different doses of infliximab was comparable, whereas TNF-int patients exhibited a dose-dependent trend. In contrast, TNF-high patients (approximately 13% of the total patients) had a clinical response to 10 mg/kg significantly better than the response to 3 and 6 mg/kg of infliximab. In TNF-high patients, the median trough serum levels of infliximab were below the detection limit (<0.1 μg/ml) at 3 and 6 mg/kg but were greater than 2 μg/ml at 10 mg/kg, whereas the levels were approximately 1 μg/ml for each dosage group in TNF-low patients. CONCLUSION In patients with RA, baseline-TNF is significantly associated with the clinical response to infliximab in patients with a high baseline-TNF. A higher dose of infliximab may be necessary in these patients, whereas lower doses of infliximab are sufficient for those with a low baseline-TNF. Baseline-TNF may be a useful measure for personalising the treatment of RA using infliximab.
