Abstract
BACKGROUND Qing-Luo-Yin (QLY) is an anti-rheumatic herbal formula. Despite the well-investigated therapeutic efficacy of QLY, its immune regulatory properties are largely unknown. CD4+ T cells and monocytes are two key parameters in rheumatoid arthritis (RA). This study investigated the changes in these cells in QLY-treated RA animal models. MATERIALS AND METHODS RA models were induced in male SD rats and were orally treated with QLY. Dynamic metabolic changes in collagen-induced arthritis (CIA) rats were monitored by 1H NMR approach. The immunity profiles of CIA and adjuvant-induced arthritis (AIA) rats were evaluated using immunohistochemical, PCR, ELISA, cytokine chip, flow cytometry, and immunofluorescence experiments. The bioactive components in QLY were identified by bioinformatic-guided LC-MS analyses. The compounds with high abundance in QLY decoction and easily absorbed were taken as key anti-rheumatic components and used to treat blood-derived immune cells using in vitro experiments. RESULTS The results indicated that QLY decreased Th17 cells frequency and T cells-released IL-6, IL-17 and GM-CSF in CIA rats, which was attributed to the impaired lymphocyte maturation and altered differentiation. QLY inhibited lactic acid production and inflammatory polarization in the monocytes during the peak period of AIA and CIA. AIA monocytes elicited significant increase in Th17 cells counts, IL-6 and IL-1β secretion in co-cultured splenocytes, which was abrogated by QLY. QLY-containing serum suppressed the phosphorylation of JNK and p65 in AIA lymphocyte-stimulated normal monocytes and consequently inhibited iNOS and IL-1β expression as well as IL-6 and IL-1β production. Matrine, sinomenine and sophocarpine were identified as major bioactive compounds in QLY. These identified compounds effectively inhibited the development of inflammatory T cells using concentrations detected in QLY-treated rats. At higher concentrations (20-fold increase), the chemical stimuli significantly suppressed the production of IL-1β in AIA monocytes by inhibiting JNK and p65 pathways. CONCLUSION By targeting inflammatory T cells and monocytes as well as disrupting their interplay, QLY improved immune environment in RA models especially during the active stages of disease.

Abstract
Rheumatoid arthritis (RA) is a multifactorial autoimmune disease of unknown etiology, primarily affecting the joints, then extra-articular manifestations can occur. Due to its complexity, which is based on an incompletely elucidated pathophysiological mechanism, good RA management requires a multidisciplinary approach. The clinical status of RA patients has improved in recent years due to medical advances in diagnosis and treatment, that have made it possible to reduce disease activity and prevent systemic complications. The most promising results were obtained by developing disease-modifying anti-rheumatic drugs (DMARDs), the class to which conventional synthetic, biologic, and targeted synthetic drugs belong. Furthermore, ongoing drug development has led to obtaining molecules with improved efficacy and safety profiles, but further research is needed until RA turns into a curable pathology. In the present work, we offer a comprehensive perspective on the management of RA, by centralizing the existing data provided by significant literature, emphasizing the importance of an early and accurate diagnosis associated with optimal personalized treatment in order to achieve better outcomes for RA patients. In addition, this study suggests future research perspectives in the treatment of RA that could lead to higher efficacy and safety profiles and lower financial costs.

Abstract
BACKGROUND Patients with moderate-to-severe rheumatoid arthritis have a heavy financial burden. The cost-effectiveness of introducing tofacitinib to the current treatment sequence for patients with moderate-to-severe rheumatoid arthritis who have inadequate response or intolerance to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs-IR) in China remains unknown. OBJECTIVE The objective of this study was to assess the cost-effectiveness of introducing tofacitinib into the current treatment sequence in China for patients with moderate-to-severe rheumatoid arthritis who have csDMARDs-IR. METHODS A Markov model was constructed from the perspective of the Chinese healthcare system to compare treatment sequences with and without first-line tofacitinib for patients with rheumatoid arthritis with csDMARDs-IR. The treatment sequence without tofacitinib included adalimumab, etanercept, recombinant human tumor necrosis factor receptor-Fc fusion protein, infliximab, and tocilizumab. Costs were derived from publicly available sources. Clinical trials, network meta-analysis, and real-world data were used to generate quality-adjusted life-years (QALYs), transition probabilities, and the incidence of adverse events. Mortality probabilities were estimated from rheumatoid arthritis-based, Chinese all-cause mortality data. One-way and probabilistic sensitivity analyses were conducted to verify the robustness of the model. In addition, the cost-effectiveness of adding tofacitinib as second- and third-line treatment options was evaluated in our analyses. Costs and effects were discounted at 5% per anum. RESULTS Compared to the current treatment sequence, adding tofacitinib as first-line treatment led to a cost-saving of $US880.11 (2018 values) and incremental QALYs of 1.34. Sensitivity analyses showed the results to be robust. Adding tofacitinib at second-line therapy was also a cost-saving option with a cost saving of $US653.65 and incremental QALYs of 1.34, while the incremental cost-effectiveness ratio of adding tofacitinib at third-line therapy was $US5588.14 per QALY gained. CONCLUSIONS Using the WHO-recommended ICER acceptability threshold of ≤ 1-time per capita Gross Domestic Product (GDP), our analysis suggests that the introduction of tofacitinib into the current treatment sequence for moderate-to-severe RA patients with csDMARDs-IR in China was a cost saving option as first- and second-line treatment, and cost-effective as a third-line treatment option. Of note, use of tofacitinib as first- and second-line treatment post-csDMARDs-IR appeared to be cost saving.

Abstract
Simultaneous blockade of immune checkpoint molecules and co-stimulation of the TNF receptor superfamily (TNFRSF) is predicted to improve overall survival in human cancer. TNFRSF co-stimulation depends upon coordinated antigen recognition through the T cell receptor followed by homotrimerization of the TNFRSF, and is most effective when these functions occur simultaneously. To address this mechanism, we developed a two-sided human fusion protein incorporating the extracellular domains (ECD) of PD-1 and OX40L, adjoined by a central Fc domain, termed PD1-Fc-OX40L. The PD-1 end of the fusion protein binds PD-L1 and PD-L2 with affinities of 2.08 and 1.76 nM, respectively, and the OX40L end binds OX40 with an affinity of 246 pM. High binding affinity on both sides of the construct translated to potent stimulation of OX40 signaling and PD1:PD-L1/L2 blockade, in multiple in vitro assays, including improved potency as compared to pembrolizumab, nivolumab, tavolixizumab and combinations of those antibodies. Furthermore, when activated human T cells were co-cultured with PD-L1 positive human tumor cells, PD1-Fc-OX40L was observed to concentrate to the immune synapse, which enhanced proliferation of T cells and production of IL-2, IFNγ and TNFα, and led to efficient killing of tumor cells. The therapeutic activity of PD1-Fc-OX40L in established murine tumors was significantly superior to either PD1 blocking, OX40 agonist, or combination antibody therapy; and required CD4+ T cells for maximum response. Importantly, all agonist functions of PD1-Fc-OX40L are independent of Fc receptor cross-linking. Collectively, these data demonstrate a highly potent fusion protein that is part of a platform, capable of providing checkpoint blockade and TNFRSF costimulation in a single molecule, which uniquely localizes TNFRSF costimulation to checkpoint ligand positive tumor cells.

Abstract
Objective To compare the 52-week efficacy and safety of SB4 [an etanercept biosimilar] with reference etanercept (ETN) in patients with active RA. Methods In a phase 3, randomized, double-blind, multicentre study, patients with moderate to severe RA despite MTX treatment were randomized to receive 50 mg/week of s.c. SB4 or ETN up to week 52. Efficacy assessments included ACR response rates, 28-joint DAS, Simplified and Clinical Disease Activity Indices and changes in the modified total Sharp score (mTSS). Safety and immunogenicity were also evaluated. Results A total of 596 patients were randomized to receive either SB4 (n = 299) or ETN (n = 297) and 505 (84.7%) patients completed 52 weeks of the study. At week 52, the ACR20 response rates in the per-protocol set were comparable between SB4 (80.8%) and ETN (81.5%). All efficacy results were comparable between the two groups and they were maintained up to week 52. Radiographic progression was also comparable and the change from baseline in the mTSS was 0.45 for SB4 and 0.74 for ETN. The safety profile of SB4 was similar to that of ETN and the incidence of anti-drug antibody development up to week 52 was 1.0 and 13.2% in the SB4 and ETN groups, respectively. Conclusion Efficacy including radiographic progression was comparable between SB4 and ETN up to week 52. SB4 was well tolerated and had a similar safety profile to that of ETN.

Abstract
Background This study evaluated the effect of early anti-tumor necrosis factor (TNF) therapy in patients with severe rheumatoid arthritis (RA) on the subsequent risk of total knee replacement (TKR) surgery. Methods This retrospective observational study included a hospital-based cohort of 200 patients diagnosed with severe RA who received treatment with anti-TNF therapy between 2003 and 2014. Clinical parameters including age, sex, body mass index, and the time from the diagnosis of RA to the initiation of anti-TNF therapy were analyzed. Results Of the 200 enrolled patients, 84 underwent an early intervention (≤3 years from the diagnosis of RA to the initiation of anti-TNF therapy), and 116 underwent a late intervention(>3 years from the diagnosis of RA to the initiation of anti-TNF therapy). Five (6.0%) patients in the early intervention group underwent TKR compared to 31 (26.7%) in the late intervention group (p = 0.023). After adjusting for confounding factors, the late intervention group still had a significantly higher risk of TKR (p = 0.004; odds ratio, 5.572; 95% confidence interval, 1.933–16.062). Those receiving treatment including methotrexate had a lower risk of TKR (p = 0.004; odds ratio, 0.287; 95% confidence interval, 0.122–0.672). Conclusions Delayed initiation of anti-TNF therapy in the treatment of severe RA was associated with an increased risk of TKR surgery. Adding methotrexate treatment decreased the risk of future TKR.

Abstract
PURPOSE In immune-mediated rheumatic diseases (IMRDs), persistence to treatment may be used as a surrogate marker for long-term treatment success. In previous comparisons of persistence to tumor necrosis factor α inhibitors (TNFis), a paucity of data for subcutaneous (SC) golimumab was identified. The aim of this study was to conduct a systematic review of persistence to SC golimumab in clinical practice and contextualize these data with five-year persistence estimates from long-term open-label extension (OLE) trials of SC TNFis in IMRDs. PATIENTS AND METHODS PubMed, Embase, MEDLINE, and conference proceedings from European League Against Rheumatism (EULAR), American College of Rheumatology (ACR), and International Society for Pharmacoeconomics and Outcomes Research (ISPOR) were searched. All studies on patients treated with SC golimumab for IMRD were included if they reported data on the persistence to golimumab. RESULTS Of 376 available references identified through the searches, 12 studies with a total of 4,910 patients met the inclusion criteria. Furthermore, nine OLE trials were available. Among the included studies from clinical practice, at six months, one year, two years, and three years, the proportion of patients persistent to treatment ranged from 63% to 91%, 47% to 80%, 40% to 77%, and 32% to 67%, respectively. In the four studies that included comparisons to other biologics, golimumab was either statistically noninferior or statistically superior to other treatments, an observation that was supported by indirect comparisons of unadjusted point estimates of OLE trials. CONCLUSION The data reviewed in this study indicate that golimumab may have higher persistence than other TNFis, a notion that is supported by indirect comparisons of persistence data from OLEs of randomized controlled trials (RCTs). Furthermore, the study suggests that persistence may be lower in biologic-experienced compared with biologic-naive patients and higher in axial spondyloarthritis compared with rheumatoid arthritis and psoriatic arthritis.

Abstract
Treatment with tumour necrosis factor (TNF) antagonists may lead to enhanced susceptibility to certain malignancies. In particular, an association is seen emerging between TNF antagonists and development of squamous cell carcinomas (SCCs) of the skin (in association with psoriasis), the oral cavity, and in the anogenital areas (possibly related to prior human papilloma virus infection). We present here a case of a 53-year old woman with a history of severe rheumatoid arthritis (RA), most recently treated with the TNF antagonist etanercept plus methotrexate, presented to our service after several months of increasing left pelvis and buttock pain. Evaluation with a computerised tomography (CT)-directed biopsy of a pelvic side wall mass revealed a metastatic SCC. On a fluorodeoxyglucose (FDG) positron-emission tomography (PET) an additional area of uptake was identified in the left posterior rectum corresponding to a 1 cm nodule palpable on digital exam. Colonoscopic biopsy revealed a basaloid SCC of the rectum as the likely primary site. Immunosuppression following TNF antagonist therapy may have given arise to this unrestrained neoplastic growth. It thereby underscores the need for an initial baseline study of risk factors and identification of patients who are at higher risk for development of a malignancy, in order to achieve a diagnosis at an early stage.

Abstract
OBJECTIVE Studies suggest nerve growth factor inhibitors (NGFi) relieve pain but may accelerate disease progression in some patients with osteoarthritis (OA). We sought cost and toxicity thresholds that would make NGFi a cost-effective treatment for moderate-to-severe knee OA. DESIGN We used the Osteoarthritis Policy (OAPol) model to estimate the cost-effectiveness of NGFi compared to standard of care (SOC) in OA, using Tanezumab as an example. Efficacy and rates of accelerated OA progression were based on published studies. We varied the price/dose from $200 to $1000. We considered self-administered subcutaneous (SC) injections (no administration cost) vs provider-administered intravenous (IV) infusion ($69-$433/dose). Strategies were defined as cost-effective if their incremental cost-effectiveness ratio (ICER) was less than $100,000/quality-adjusted life year (QALY). In sensitivity analyses we varied efficacy, toxicity, and costs. RESULTS SOC in patients with high levels of pain led to an average discounted quality-adjusted life expectancy of 11.15 QALYs, a lifetime risk of total knee replacement surgery (TKR) of 74%, and cumulative discounted direct medical costs of $148,700. Adding Tanezumab increased QALYs to 11.42, reduced primary TKR utilization to 63%, and increased costs to between $155,400 and $199,500. In the base-case analysis, Tanezumab at $600/dose was cost-effective when delivered outside of a hospital. At $1000/dose, Tanezumab was not cost-effective in all but the most optimistic scenario. Only at rates of accelerated OA progression of 10% or more (10-fold higher than reported values) did Tanezumab decrease QALYs and fail to represent a viable option. CONCLUSIONS At $100,000/QALY, Tanezumab would be cost effective if priced ≤$400/dose in all settings except IV hospital delivery.

Certolizumab pegol plus methotrexate 5-year results from the rheumatoid arthritis prevention of structural damage (RAPID) 2 randomized controlled trial and long-term extension in rheumatoid arthritis patients. Arthritis Res Ther 2015; 17:245. [PMID: 26353833 PMCID: PMC4565002 DOI: 10.1186/s13075-015-0767-2] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2015] [Accepted: 08/25/2015] [Indexed: 01/22/2023] Open
Abstract
Introduction As patients with rheumatoid arthritis (RA) receive treatment with anti-tumour necrosis factors over several years, it is important to evaluate their long-term safety and efficacy. The objective of this study was to examine the safety and benefits of certolizumab pegol (CZP)+methotrexate (MTX) treatment for almost 5 years in patients with RA. Methods Patients who completed the 24-week Rheumatoid Arthritis Prevention of Structural Damage (RAPID) 2 randomized controlled trial (RCT; NCT00160602), or who were American College of Rheumatology (ACR) 20 non-responders at Week 16, entered the open-label extension (OLE; NCT00160641). After ≥6 months treatment with CZP 400 mg every two weeks (Q2W), dose was reduced to 200 mg Q2W, the approved maintenance dose. Safety data are presented from all patients who received ≥1 dose CZP (Safety population, n=612). Efficacy data are presented to Week 232 for the intent-to-treat (ITT, n=492) and Week 24 CZP RCT Completer (n=342) populations, and through 192 weeks of dose-reduction for the Dose-reduction population (patients whose CZP dose was reduced to 200 mg, n=369). Radiographic progression (modified total Sharp score change from RCT baseline >0.5) to Week 128 is reported for the Week 24 CZP Completers. Results In the RCT, 619 patients were randomized to CZP+MTX (n=492) or placebo+MTX (n=127). Overall, 567 patients (91.6%) entered the OLE: 447 CZP and 120 placebo patients. Of all randomized patients, 358 (57.8%) were ongoing at Week 232. Annual drop-out rates during the first four years ranged from 8.4–15.0%. Event rates per 100 patient-years were 163.0 for adverse events (AEs) and 15.7 for serious AEs. Nineteen patients (3.1%) had fatal AEs (incidence rate=0.8). Clinical improvements in the RCT were maintained to Week 232 in the CZP Completers: mean Disease Activity Score 28 (Erythrocyte Sedimentation Rate) change from baseline was −3.4 and ACR20/50/70 responses 68.4%/47.1%/25.1% (non-responder imputation). Similar improvements observed in the ITT were maintained following dose-reduction. 73.2% of CZP Completers had no radiographic progression at Week 128. Conclusions In patients with active RA despite MTX therapy, CZP was well tolerated, with no new safety signals identified. CZP provided sustained improvements in clinical outcomes for almost 5 years. Trial registration ClinicalTrials.gov, NCT00160602 and NCT00160641. Registered 8 September 2005.

Abstract
With its approval more than 15 years ago, subcutaneous etanercept (Enbrel(®)) was the first biological disease-modifying antirheumatic drug (bDMARD) and the first tumour necrosis factor inhibitor to be approved for use in rheumatic diseases. Etanercept remains an important cost-effective treatment option in adult patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis or plaque psoriasis, and in paediatric patients with juvenile idiopathic arthritis or plaque psoriasis. In all of these populations, etanercept (with or without methotrexate) effectively reduced signs and symptoms, disease activity and disability, and improved health-related quality of life, with these benefits sustained during long-term treatment. The safety profile of etanercept during short- and long-term treatment was consistent with the approved product labelling, with adverse events being of a predictable and manageable nature. The introduction of etanercept and other bDMARDs as therapeutic options for patients with autoimmune rheumatic diseases and spondyloarthropathies revolutionized disease management and these agents continue to have a central role in treatment strategies. This article reviews the extensive clinical experience with etanercept in these patient populations.

Abstract
OBJECTIVE To report the long-term safety data of certolizumab pegol (CZP) in rheumatoid arthritis (RA) accumulated as of 30 November 2011. DESIGN Data from 10 completed randomised controlled trials (RCT) of CZP in RA and several open-label extensions (OLE) were pooled across all doses. Reported adverse events (AE) occurred between the first dose and 84 days after the last dose. All deaths, serious infectious events (SIE) and malignancies were reviewed by external experts, classified according to predefined rules, and validated by an external steering committee. Incidence rates (IR) and event rates (ER) per 100 patient-years (PY) are presented. RESULTS 4049 RA patients who received CZP were included in the safety pooling; total exposure 9277 PY, mean exposure 2.1 years (range 0.04-7.6). SIE, most frequently pneumonia (IR 0.73/100 PY), were the most common serious AE, occurring more frequently in CZP compared to placebo-treated patients in RCT (IR 5.61/100 PY vs 1.35/100 PY, odds ratio (OR) 4.35, 95% CI 0.65 to 29.30). SIE rates were lower in the CZP-treated population including OLE (ER 4.33/100 PY). 44 patients developed tuberculosis (IR 0.47/100 PY), 39 from high endemic regions. 58 deaths occurred in CZP-exposed patients (IR 0.63/100 PY) and 70 developed malignancies excluding non-melanoma skin cancer (IR 0.76/100 PY), including five lymphomas (IR 0.05/100 PY). CONCLUSIONS No new or unexpected safety signals associated with CZP emerged in this updated long-term safety analysis. While SIE rates were higher for CZP than for placebo in RCT, the rate decreased with continued exposure to CZP. These rates are consistent with data previously reported for CZP and other tumour necrosis factor inhibitors.

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
OBJECTIVES To compare the risk of infection for rheumatoid arthritis (RA) patients who took etanercept or adalimumab medication in a nationwide population. METHODS RA patients who took etanercept or adalimumab were identified in the Taiwan's National Health Insurance Research Database. The composite outcome of serious infections, including hospitalization for infection, reception of an antimicrobial injection, and tuberculosis were followed for 365 days. A Kaplan-Meier survival curve with a log-rank test and Cox proportional hazards regression were used to compare risks of infection between the two cohorts of tumor necrosis factor (TNF)-α antagonists users. Hazard ratios (HRs) were obtained and adjusted with propensity scores and clinical factors. Sensitivity analyses and subgroup analyses were also performed. RESULTS In total, 1660 incident etanercept users and 484 incident adalimumab users were eligible for the analysis. The unadjusted HR for infection of the etanercept users was significantly higher than that of the adalimumab users (HR: 1.93; 95% confidence interval (CI): 1.09-3.42; p=0.024). The HRs were 2.04 (95% CI: 1.14-3.65; p=0.016) and 2.02 (95% CI: 1.13-3.61; p=0.018) after adjusting for propensity scores and for propensity scores in addition to clinical factors, respectively. The subgroup analyses revealed that HRs for composite infection was significantly higher in patient subgroups of older age, female, as well as patients who did not have DM, COPD, and hospitalization history at the baseline. CONCLUSION In this head-to-head cohort study involving a nationwide population of patients with RA, etanercept users demonstrated a higher risk of infection than adalimumab users. Results of this study suggest the possible existence of an intra-class difference in infection risk among TNF-α antagonists.

Abstract
OBJECTIVE Evaluate the safety and efficacy of longterm abatacept (ABA) treatment over 5 years in methotrexate (MTX)-refractory patients with rheumatoid arthritis (RA). METHODS Patients from the 1-year, double-blind Abatacept in Inadequate Responders to Methotrexate (AIM) study (NCT00048568) received open-label ABA (∼10 mg/kg) in the longterm extension (LTE). Safety was assessed for patients who received ≥ 1 ABA dose, and efficacy for patients randomized to ABA and treated in the LTE. Radiographs were evaluated for changes in Genant-modified Sharp scores. RESULTS Out of 652 patients, 539 entered the LTE (ABA, n = 378; placebo, n = 161). At Year 5, 72.4% were ongoing; discontinuation rates declined over time. Incidence rates of serious adverse events, serious infections, malignancies, and autoimmune events were 13.87, 2.84, 1.45, and 0.99 events/100 patient-years exposure, respectively. American College of Rheumatology 20 response was 82.3% (n = 373) and 83.6% (n = 268) at years 1 and 5, respectively. Disease Activity Score 28 C-reactive protein (DAS28-CRP) < 2.6 and ≤ 3.2 were achieved by 25.4% and 44.1% of patients at Year 1 (n = 370), and 33.7% and 54.7% at Year 5 (n = 267), respectively. Mean changes in DAS28-CRP and Health Assessment Questionnaire-Disability Index at Year 1 [-2.83 (n = 365) and -0.68 (n = 369)] were maintained at Year 5 [-3.14 (n = 264) and -0.77 (n = 271)] for patients continuing treatment. Of them, 59.5% (n = 291) and 45.1% (n = 235) remained free from radiographic progression at years 1 and 5, respectively. CONCLUSION In MTX-refractory patients with RA, longterm ABA treatment was well tolerated and provided consistent safety and sustained efficacy, with high patient retention. Radiographic progression continued to be inhibited with ongoing treatment.

Abstract
Etanercept is an anti-tumor necrosis factor α receptor agent used to treat inflammatory conditions. Previous reports described rapid development of skin squamous cell carcinoma (SCC) after etanercept use. This report describes a novel case of oropharyngeal SCC associated with the use of etanercept. A 45-year-old man with rheumatoid arthritis developed oropharyngeal pain within 2 months after the start of etanercept therapy and was diagnosed with tonsillar carcinoma. This patient had other exposures that increase the risk of oropharyngeal cancer, such as tobacco and alcohol use. However, owing to the timing of onset of his initial symptoms, etanercept should be considered as a possible factor in the etiology or progression of his tumor, especially in the context of reported skin SCC after etanercept therapy in patients at risk for SCC. Clinicians should be alert to signs of malignancy in patients on etanercept, particularly those at high risk for skin or head and neck cancers.

Abstract
The objective of this study was to investigate patients' perceptions of the acceptability of two devices delivering etanercept for rheumatoid arthritis (RA) treatment and to explore whether specific patients' attributes are associated with device preferences. Two similar multicenter, open-label, randomised, parallel-design studies were conducted in a total of 13 European countries. A total of 640 adult patients with RA were randomised to receive etanercept 50 mg once-weekly subcutaneously for 12 weeks in either a pre-filled syringe (PFS) or a pre-filled pen (PFP). Patient satisfaction at week 12 was measured on a 0- to 10-point Likert scale (primary endpoint). The study was powered to demonstrate non-inferiority of a PFP over PFS for the primary endpoint. At week 12, mean patient satisfaction was 8.3 (± 2.4) points in the pen group and 7.2 (± 2.6) points in the syringe group. Non-inferiority and even superiority of the pen over the syringe was demonstrated. In conclusion, this study showed higher patient satisfaction in the group of patients injecting etanercept with a PFP compared with the group of patients using a PFS.

Abstract
BACKGROUND Etanercept is a soluble tumour necrosis factor alpha-receptor disease-modifying anti-rheumatic drug (DMARD) for the treatment of rheumatoid arthritis (RA). OBJECTIVES The purpose of this review was to update the previous Cochrane systematic review published in 2003 assessing the benefits and harms of etanercept for the treatment of RA. In addition, we also evaluated the benefits and harms of etanercept plus DMARD compared with DMARD monotherapy in those people with RA who are partial responders to methotrexate (MTX) or any other traditional DMARD. SEARCH METHODS Five electronic databases were searched from 1966 to February 2003 with no language restriction. The search was updated to January 2012. Attempts were made to identify other studies by contact with experts, searching reference lists and searching trial registers. SELECTION CRITERIA All controlled trials (minimum 24 weeks' duration) comparing four possible combinations: 1) etanercept (10 mg or 25 mg twice weekly) plus a traditional DMARD (either MTX or sulphasalazine) versus a DMARD, 2) etanercept plus DMARD versus etanercept alone, 3) etanercept alone versus a DMARD or 4) etanercept versus placebo. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data and assessed the risk of bias of the trials. MAIN RESULTS Three trials were included in the original version of the review. An additional six trials, giving a total of 2842 participants, were added to the 2012 update of the review. The trials were generally of moderate to low risk of bias, the majority funded by pharmaceutical companies. Follow-up ranged from six months to 36 months.BenefitAt six to 36 months the American College of Rheumatology (ACR) 50 response rate was statistically significantly improved with etanercept plus DMARD treatment when compared with a DMARD in those people who had an inadequate response to any traditional DMARD (risk ratio (RR) 2.0; 95% confidence interval (CI) 1.3 to 2.9, absolute treatment benefit (ATB) 38%; 95% CI 13% to 59%) and in those people who were partial responders to MTX (RR 11.7; 95% CI 1.7 to 82.5, ATB 36%). Similar results were observed when pooling data from all participants (responders or not) (ACR 50 response rates at 24 months: RR 1.9; 95% CI 1.3 to 2.8, ATB 29%; 36 months: RR 1.6; 95% CI 1.3 to 1.9, ATB 24%). Statistically significant improvement in physical function and a higher proportion of disease remission were observed in combination-treated participants compared with DMARDs alone ((mean difference (MD) -0.36; 95% CI -0.43 to -0.28 in a 0-3 scale) and (RR 1.92; 95% CI 1.60 to 2.31), respectively) in those people who had an inadequate response to any traditional DMARD. All changes in radiographic scores were statistically significantly less with combination treatment (etanercept plus DMARD) compared with MTX alone for all participants (responders or not) (Total Sharp Score (TSS) (scale = 0 to 448): MD -2.2, 95% CI -3.0 to -1.4; Erosion Score (ES) (scale = 0 to 280): MD -1.6; 95% CI -2.4 to -0.9; Joint Space Narrowing Score (JSNS) (scale = 0 to 168): MD -0.7; 95% CI -1.1 to -0.2), and with combination treatment compared with etanercept alone (TSS: MD -1.1; 95% CI -1.8 to -0.5; ES: MD -0.7; 95% CI -1.1 to -0.2; JSNS: MD -0.5, 95% CI -0.7 to -0.2). The estimate of irreversible physical disability over 10 years given the radiographic findings was 0.45 out of 3.0.When etanercept monotherapy was compared with DMARD monotherapy, there was generally no evidence of a difference in ACR50 response rates when etanercept 10 mg or 25 mg was used; at six months etanercept 25 mg was significantly more likely to achieve ACR50 than DMARD monotherapy but this difference was not found at 12, 24 or 36 months. TSS and ES radiographic scores were statistically significantly improved with etanercept 25 mg monotherapy compared with DMARD (TSS: MD -0.7; 95% CI -1.4 to 0.1; ES: MD -0.7; 95% CI -1.0 to -0.3) but there was no evidence of a statistically significant difference between etanercept 10 mg monotherapy and MTX.HarmsThere was no evidence of statistically significant differences in infections or serious infections between etanercept plus DMARD and DMARD alone at any point in time. Infection rates were higher in people receiving etanercept monotherapy compared with DMARD; however, there were no differences regarding serious infections. For those participants who had an inadequate response to DMARDs, the rate of total withdrawals was lower for the etanercept plus DMARD group compared with DMARD alone (RR 0.53; 95% CI 0.36 to 0.77, ATB 18%). No other statistically significant differences were observed in any of the assessed comparisons. AUTHORS' CONCLUSIONS Etanercept 25 mg administered subcutaneously twice weekly together with MTX was more efficacious than either etanercept or MTX monotherapy for ACR50 and it slowed joint radiographic progression after up to three years of treatment for all participants (responders or not). There was no evidence of a difference in the rates of infections between groups.

Abstract
Estimates of relative efficacy between alternative treatments are crucial for decision making in health care. Bayesian mixed treatment comparison models provide a powerful methodology to obtain such estimates when head-to-head evidence is not available or insufficient. In recent years, this methodology has become widely accepted and applied in economic modelling of healthcare interventions. Most evaluations only consider evidence from randomized controlled trials, while information from other trial designs is ignored. In this paper, we propose three alternative methods of combining data from different trial designs in a mixed treatment comparison model. Naive pooling is the simplest approach and does not differentiate between-trial designs. Utilizing observational data as prior information allows adjusting for bias due to trial design. The most flexible technique is a three-level hierarchical model. Such a model allows for bias adjustment while also accounting for heterogeneity between-trial designs. These techniques are illustrated using an application in rheumatoid arthritis.

Abstract
OBJECTIVE To examine the effect of intensive lipid-lowering therapy on a composite cardiovascular outcome (cardiovascular disease [CVD]), consisting of mortality and morbidity end points, in patients with inflammatory joint disease (rheumatoid arthritis [RA], ankylosing spondylitis [AS], or psoriatic arthritis [PsA]) by post hoc analysis of 2 prospective trials of statins with a secondary end point of CVD outcome (the Treating to New Targets [TNT] and Incremental Decrease in End Points Through Aggressive Lipid Lowering [IDEAL] studies). METHODS Of the 18,889 patients participating in the 2 trials, 199 had RA, 46 had AS, and 35 had PsA. Lipid-lowering therapy consisted of an intensive regimen of atorvastatin 80 mg or a conventional/low-dose regimen of atorvastatin 10 mg or simvastatin 20-40 mg. The median duration of followup was nearly 5 years. Changes in lipid levels were examined by analyses of covariance. The effect on CVD was examined by Cox regression analyses, and heterogeneity tests were performed. RESULTS Patients with RA and those with AS had lower baseline cholesterol levels than patients without inflammatory joint disease (least squares mean ± SEM 180.7 ± 2.3 mg/dl and 176.5 ± 4.7 mg/dl, respectively, versus 185.6 ± 0.2 mg/dl; P = 0.03 and P = 0.05, respectively). Statin treatment led to a comparable decrease in lipid levels and a 20% reduction in overall risk of CVD in both patients with and those without inflammatory joint disease. CONCLUSION Our findings indicate that patients with and those without inflammatory joint disease experience comparable lipid-lowering effects and CVD risk reduction after intensive treatment with statins.

INTRODUCTION This paper aims to estimate the annual cost of etanercept, adalimumab, and infliximab per treated patient across adult indications using US-managed care drug use data. METHODS Adult patients who used etanercept, adalimumab, or infliximab were identified in the Thomson Reuters MarketScan® Commercial Claims and Encounters Database (Thomson Reuters Healthcare, Ann Arbor, MI, USA) between January 1, 2005 and June 30, 2009. The index event was the first use of etanercept, adalimumab, or infliximab preceded by a diagnosis for rheumatoid arthritis, psoriasis, psoriatic arthritis, or ankylosing spondylitis. Patients were defined as either newly initiating or continuing tumor necrosis factor (TNF) blocker treatment based on their use during the 6 months before the index event. Annual cost per treated patient was the sum of the etanercept, adalimumab, and infliximab medication and administration costs during the 12 months following the index claim. Annual costs were calculated across all patients as well as within each indication group and patient type (new initiator or continuing). RESULTS In total, 21,652 patients met the study criteria (etanercept n = 12,065; adalimumab n = 5,685; infliximab n = 3,902); 43% of patients were new initiators. Patient characteristics were similar across treatment groups in terms of age (mean = 49, SD = 10) and gender (66% female). Across indications, the mean annual TNF-blocker cost per treated patient was $15,345 for etanercept, $18,046 for adalimumab, and $24,018 for infliximab. In new initiators, the TNF-blocker cost per treated patient across indications was $14,543 for etanercept, $16,978 for adalimumab, and $21,086 for infliximab; among patients continuing therapy, annual costs were $15,836 for etanercept, $19,457 for adalimumab, and $25,748 for infliximab. CONCLUSION Patients on etanercept had the lowest TNF-blocker cost per treated patient for adult indications when applying actual drug use from a US-managed care population. TNF-blocker costs per treated patient on adalimumab and infliximab were approximately 18% and 57% higher than etanercept, respectively, using real-world drug use data.

Abstract
Blau syndrome is a rare autoinflammatory disorder within the group of pediatric granulomatous diseases. Mutations in nucleotide-binding oligomerization domain 2 (NOD2/CARD15) are responsible for this condition, which has an autosomal dominant pattern of inheritance and variable expressivity. The clinical picture includes arthritis, uveitis, skin rash, and granulomatous inflammation. Central nervous system involvement is seldom reported, although some isolated cases of seizures, neurosensorial hearing loss, and transient cranial nerve palsy have been described. Treatment consists of nonsteroidal anti-inflammatory drugs, corticosteroids, and immunosuppressive agents, among which anti-tumor-necrosis-factor-alpha (TNF-α) biologic agents, such as etanercept, play an important role. Among the major adverse effects of TNF-α inhibitors, demyelinating disease, multiple sclerosis, and acute transverse myelitis have been reported in adults. We describe a case of pediatric Blau syndrome affected by etanercept-induced myelopathy, manifesting as a clinical syndrome of transverse myelitis. The patient experienced rapid recovery after etanercept was discontinued. To our knowledge, this is the first such case reported in the literature and, possibly, the one with the latest onset, following 8 years of treatment. We discuss the etiopathogenic mechanisms of this reaction and possible explanations for the imaging findings.

Abstract
OBJECTIVE This study uses real-world US managed-care claims data to estimate dose escalation rates over the first and second years of therapy among biologic naïve rheumatoid arthritis (RA) patients initiating tumor necrosis factor (TNF) blocker therapy with etanercept, adalimumab, or infliximab. METHODS Non-elderly adult (age 18-65 years) RA patients initiating etanercept, adalimumab, or infliximab from July 1, 2005 to April 30, 2009, were identified using the MarketScan Commercial Database. National and regional dose-escalation patterns were evaluated 12 and 24 months after initiation. In the single-instance method, dose escalation was defined as having one average weekly dose 115%, 130%, or 150% greater than the initial average weekly dose. By the two-instances method, dose escalation was defined as having two consecutive claims with an average weekly dose 115% or 130% greater than the initial average weekly dose. RESULTS A total of 2747 patients met the inclusion criteria (mean age 50 years [SD=10]; 74% female). More patients initiated etanercept (44%) than adalimumab (37%) or infliximab (20%). Using the single-instance method, dose escalation at 12 months ranges were 0.8-1.5% for etanercept, 10.8-12.5% for adalimumab, and 16.4-42.5% for infliximab; ranges at 24 months were 0.8-2.1% for etanercept, 14.3-17.5% for adalimumab, and 26.4-57.6% for infliximab. The two-instances method showed a similar relationship among the treatment cohorts at both 12 and 24 months, with lower dose-escalation rates for etanercept (0.8%, 0.8%) than adalimumab (8.7%, 13.3%) or infliximab (22.9%, 37.6%) at the 130% threshold (p<0.001). Dose-escalation rates for etanercept, adalimumab, and infliximab were consistent across US geographic regions. CONCLUSION Patients initiating etanercept had lower rates of dose escalation than patients initiating adalimumab or infliximab in the first and second year following therapy initiation, as well as across US geographic regions. These results may not be generalizable to the entire US RA population.

Abstract
Objective To evaluate abatacept treatment over 3 years in patients with rheumatoid arthritis (RA) refractory to methotrexate (MTX). Methods Patients randomised to abatacept or placebo (+MTX) during the 1-year double-blind period of the Abatacept in Inadequate responders to Methotrexate (AIM) trial received open-label abatacept (+MTX) in the long-term extension (LTE). Safety was assessed for patients who received ≥1 dose of abatacept, regardless of randomisation group. Efficacy was assessed for patients randomised to abatacept who entered the LTE. Results 433 and 219 patients were randomised and treated with abatacept or placebo, respectively; 378 and 161 entered the LTE. At year 3, 440/539 patients were ongoing. No unexpected safety events were observed in the LTE. By year 3, incidence rates of adverse event and serious adverse events were 249.8/100 and 15.1/100 patient-years, respectively. Incidence rates were generally stable over time. At year 3, 84.8%, 63.4% and 37.5% of patients achieved American College of Rheumatology (ACR) criteria of 20, 50 and 70, respectively, compared with 82.3%, 54.3% and 32.4% of patients at year 1. Mean changes in Genant-modified Sharp scores were reduced progressively over 3 years, with significantly greater inhibition during year 3 compared with year 2 (p=0.022 for total score). Conclusion In MTX-inadequate responders with RA, abatacept provided consistent safety and sustained efficacy over 3 years. The data suggest an increasing inhibitory disease-modifying effect on radiographic progression.

Abstract
OBJECTIVE An association between therapeutic inhibition of tumor necrosis factor (TNF) and solid malignancies was observed during the Wegener's Granulomatosis Etanercept Trial (WGET), which included 180 patients with granulomatosis with polyangiitis (Wegener's) (GPA). The present study was conducted to determine the malignancy risk beyond the time of exposure to study therapy. METHODS The occurrence and type of solid malignancies were ascertained using a standardized data form. Data collected included vital status, histologic findings, and therapeutic interventions. The Surveillance, Epidemiology, and End-Results database was used to estimate a standardized incidence rate (SIR) for solid malignancies. RESULTS Post-trial followup data were available for 153 patients (85% of the original cohort), with a median followup time of 43 months. Fifty percent of these patients had received etanercept. There were no differences in demographic characteristics between the etanercept and placebo groups. Thirteen new solid malignancies were detected, 8 in the etanercept group and 5 in the placebo group. Compared to the general population, the risk of solid malignancies in the etanercept group was increased (SIR 3.92 [95% confidence interval 1.69-7.72]), but was not different from the risk in the placebo group compared to the general population (SIR 2.89 [95% confidence interval 0.94-6.73]). All solid malignancies occurred in patients who had been exposed to cyclophosphamide. The overall duration of disease and a history of malignancy before trial enrollment were associated with the development of malignancy during post-trial followup. CONCLUSION The incidence of solid malignancy remained increased during long-term followup of the WGET cohort. However, this could not be attributed solely to etanercept exposure during the trial. Anti-TNF therapy with etanercept appears to further increase the risk of malignancy observed in patients with GPA treated with cytotoxic agents and should be avoided in these patients.

Abstract
BACKGROUND Multiple trials demonstrate the tolerability and safety of etanercept. However, there are limited data on etanercept tolerability in large populations of patients with psoriasis or with extended therapy. OBJECTIVES We sought to determine whether there is an increased safety risk associated with higher etanercept doses or with extended exposure in patients with psoriasis. METHODS Integrated adverse event (AE) data from etanercept psoriasis trials were used to evaluate short-term (up to 12 weeks from controlled studies) and long-term (up to 144 weeks from uncontrolled extension studies) safety of etanercept (25 mg once weekly to 50 mg twice weekly). Long-term data were stratified by treatment regimens. Rates of noninfectious and infectious AE and standardized incidence ratios for malignancies were determined. RESULTS In short-term analyses, rates of noninfectious and infectious AE and serious noninfectious and infectious AE were comparable between placebo and etanercept groups. In both short- and long-term analyses, there were no dose-related increases in these events. Cumulative event rates for serious infections were not significantly different across dose groups and over time. The standardized incidence ratios for malignancies excluding nonmelanoma skin cancers did not achieve statistical significance. There was no increase in overall malignancies with etanercept therapy compared with the psoriasis population. Lymphoma (n = 2 patients), demyelination (n = 2), congestive heart failure (n = 7), and opportunistic infection (n = 1) were rare. LIMITATIONS Study limitations include the rarity of some events and the resultant broad 95% confidence intervals. CONCLUSIONS In this integrated analysis, etanercept was well tolerated, and there were no signs of dose-related or cumulative toxicity over time.

Abstract
BACKGROUND Biologics are used for the treatment of rheumatoid arthritis and many other conditions. While the efficacy of biologics has been established, there is uncertainty regarding the adverse effects of this treatment. Since serious risks such as tuberculosis (TB) reactivation, serious infections, and lymphomas may be common to the biologics but occur in small numbers across the various indications, we planned to combine the results from biologics used in many conditions to obtain the much needed risk estimates. OBJECTIVES To compare the adverse effects of tumor necrosis factor blocker (etanercept, adalimumab, infliximab, golimumab, certolizumab), interleukin (IL)-1 antagonist (anakinra), IL-6 antagonist (tocilizumab), anti-CD28 (abatacept), and anti-B cell (rituximab) therapy in patients with any disease condition except human immunodeficiency disease (HIV/AIDS). METHODS Randomized controlled trials (RCTs), controlled clinical trials (CCTs) and open-label extension (OLE) studies that studied one of the nine biologics for use in any indication (with the exception of HIV/AIDS) and that reported our pre-specified adverse outcomes were considered for inclusion. We searched The Cochrane Library, MEDLINE, and EMBASE (to January 2010). Identifying search results and data extraction were performed independently and in duplicate. For the network meta-analysis, we performed mixed-effects logistic regression using an arm-based, random-effects model within an empirical Bayes framework. MAIN RESULTS We included 163 RCTs with 50,010 participants and 46 extension studies with 11,954 participants. The median duration of RCTs was six months and 13 months for OLEs. Data were limited for tuberculosis (TB) reactivation, lymphoma, and congestive heart failure. Adjusted for dose, biologics as a group were associated with a statistically significant higher rate of total adverse events (odds ratio (OR) 1.19, 95% CI 1.09 to 1.30; number needed to treat to harm (NNTH) = 30, 95% CI 21 to 60) and withdrawals due to adverse events (OR 1.32, 95% CI 1.06 to 1.64; NNTH = 37, 95% CI 19 to 190) and an increased risk of TB reactivation (OR 4.68, 95% CI 1.18 to 18.60; NNTH = 681, 95% CI 143 to 14706) compared to control.The rate of serious adverse events, serious infections, lymphoma, and congestive heart failure were not statistically significantly different between biologics and control treatment. Certolizumab pegol was associated with significantly higher risk of serious infections compared to control treatment (OR 3.51, 95% CI 1.59 to 7.79; NNTH = 17, 95% CI 7 to 68). Infliximab was associated with significantly higher risk of withdrawals due to adverse events compared to control (OR 2.04, 95% CI 1.43 to 2.91; NNTH = 12, 95% CI 8 to 28). Indirect comparisons revealed that abatacept and anakinra were associated with a significantly lower risk of serious adverse events compared to most other biologics. Although the overall numbers are relatively small, certolizumab pegol was associated with significantly higher odds of serious infections compared to etanercept, adalimumab, abatacept, anakinra, golimumab, infliximab, and rituximab; abatacept was significantly less likely than infliximab and tocilizumab to be associated with serious infections. Abatacept, adalimumab, etanercept and golimumab were significantly less likely than infliximab to result in withdrawals due to adverse events. AUTHORS' CONCLUSIONS Overall, in the short term biologics were associated with significantly higher rates of total adverse events, withdrawals due to adverse events and TB reactivation. Some biologics had a statistically higher association with certain adverse outcomes compared to control, but there was no consistency across the outcomes so caution is needed in interpreting these results.There is an urgent need for more research regarding the long-term safety of biologics and the comparative safety of different biologics. National and international registries and other types of large databases are relevant sources for providing complementary evidence regarding the short- and longer-term safety of biologics.

Abstract
OBJECTIVES Experience with anti-TNF agents for a decade can be used to research the safety and effectiveness of anti-TNF agents in the long term. The objective of this article is to describe drug survival, disease activity, daily functioning, quality of life and adverse events of TNF-blocking agents in daily clinical practice after 5 years of follow-up. METHODS Data from the Dutch Rheumatoid Arthritis Monitoring (DREAM) register of 1560 RA patients were used for analyses (5-year follow-up, n=174). Drug survival and time to first serious infection or malignancy were analysed by Kaplan-Meier analysis. Several outcome measures at several follow-up moments were analysed per intention to treat and per protocol. RESULTS The 5-year drug survival of the first anti-TNF was 45%, and 60% for total use of TNF-blocking agents. Baseline 28-joint DAS (DAS-28) was 5.1 (s.d. 1.3). After 5 years, the mean DAS-28 was 3.2 (s.d. 1.3) in all patients who had started with TNF-blocking agents and 2.9 (s.d. 1.1) in patients who were still on TNF-blocking agents. In the latter group, the HAQ score was 0.88 (s.d. 0.7) and the EuroQol five dimensions (EQ-5D) utility score was 0.7 (s.d. 0.2). Incidence rates of serious infections and malignancies were 2.9 and 0.6 per 100 patient-years, respectively. CONCLUSION Five-year follow-up of RA patients treated with TNF-blocking agents showed a 60% drug survival accompanied by sustained low disease activity, normalized function and quality of life similar to that in the general population. The benefit to risk ratio for long-term TNF-blocking therapy remains favourable.

Abstract
Significant advances in our understanding of RA and its management have been made in the past decade, resulting in earlier intervention with biologic DMARDs, particularly in patients with evidence of aggressive, erosive disease. Here, one such biologic therapy, the T-cell co-stimulation modulator abatacept, is discussed, exploring clinical evidence published to date on its use in patients with very early arthritis/early RA who are MTX naïve, and in patients with established RA and an inadequate response to MTX or TNF antagonists. Data from relevant clinical trials are overviewed, discussing the clinical efficacy of abatacept in early disease, the clinical outcomes over long-term treatment in different patient populations and the effects of abatacept on structural damage. Findings from integrated safety analyses of abatacept clinical trial data, representing 10 366 patient-years of exposure are described, and clinically important safety events, including serious infections, malignancies and autoimmune events, are highlighted. It is concluded that abatacept represents an effective treatment option with an established safety profile across different patient populations, including patients with both early and erosive RA and those with established disease. Furthermore, efficacy data from studies in patients with early disease suggest that the risk–benefit profile of abatacept may be more favourable when introduced earlier in the treatment paradigm.

Abstract
OBJECTIVE It is unclear if skin cancer risk is affected by the use of immunomodulatory medications in rheumatoid arthritis (RA), psoriasis, and psoriatic arthritis (PsA). The purpose of this study is to evaluate and summarize the available data pertinent to this question. METHODS The English language literature on PubMed was searched with a combination of phrases, including "malignancy," "skin cancer," "squamous cell carcinoma," "basal cell carcinoma," "melanoma," "psoriasis," "psoriatic arthritis," and "rheumatoid arthritis" in addition to the generic names of a variety of common immunomodulatory drugs. Relevant articles were identified and data were extracted. RESULTS In total, 2218 potentially relevant articles were identified through the search process. After further screening, 20 articles relevant to RA were included. An additional 19 articles relevant to either psoriasis or PsA were included as well. RA may be a risk factor for the development of cutaneous malignancy. Treatment with tumor necrosis factor inhibitors increases the rates of non-melanoma skin cancer (NMSC) in RA and psoriasis. This risk doubles when combination methotrexate therapy is used in RA. Methotrexate may increase the risk of malignant melanoma in patients with RA and the risk of NMSC in psoriasis. Cyclosporine and prior phototherapy significantly increase the risk of NMSC. CONCLUSION RA may potentiate the risk of cutaneous malignancy and therefore dermatologic screening in this population should be considered. The use of immunomodulatory therapy in RA, psoriasis, and PsA may further increase the risk of cutaneous malignancy and therefore dermatologic screening examinations are warranted in these groups. More careful recording of skin cancer development during clinical trials and cohort studies is necessary to further delineate the risks of immunomodulatory therapy.

Abstract
BACKGROUND Anti-tumor necrosis factor (anti-TNF) biologic agents have been associated with a number of adverse events. OBJECTIVE To review the cutaneous reactions that have been reported in patients receiving anti-TNF therapy. METHODS We performed a systematic MEDLINE search of relevant publications, including case reports and case series. RESULTS Reported cutaneous events included infusion and injection site reactions, psoriasiform eruptions, lupus-like disorders, vasculitis, granulomatous reactions, cutaneous infections, and cutaneous neoplasms. Infusion reactions and injection site reactions were definitely associated with anti-TNF administration, whereas all other events had a varying strength of association and severity, not necessarily requiring drug discontinuation. LIMITATIONS Most information was derived from spontaneous case reports, where ascertainment biases and frequency of reporting may impair detection methodology and causal relationships. CONCLUSIONS As anti-TNF biologic agents are progressively being used in clinical practice, cutaneous adverse events will be encountered more frequently. Until more data are accumulated with respect to their pathogenesis and potential association with anti-TNF therapy, dermatologists should become more familiar with the clinical presentation and management of such events.

Abstract
Adalimumab, a fully humanized monoclonal antibody against tumor necrosis factor-alpha (TNFα), has been evaluated in various randomized placebo-controlled trials in rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and juvenile idiopathic arthritis. In the short time frame of these trials adalimumab has been shown to be effective in reducing disease activity, slowing radiographic disease progression and improving patients' quality of life, while at the same time demonstrating an acceptable safety profile. Furthermore, release of adalimumab on the market, prospective observational studies, as well as open-label extensions of the original double-blind trials have provided experience and data about the long-term efficacy and safety of the drug. Initial effectiveness, in terms of reducing disease activity, is sustained, while in most cases patients treated with adalimumab experienced a slower radiographic progression and consequently less disability and improved health-related quality-of-life outcomes. Moreover, long-standing treatment of thousands of patients with adalimumab outside the controlled context of clinical trials was not related to new safety signals, with the most common adverse events being respiratory infections. The most common serious adverse events seem to be tuberculosis reactivation, while a putative association with malignant lymphoma development is not yet proven. Besides, both of these adverse reactions pertain to the whole TNFα blocker group. In conclusion, adalimumab is a safe and effective option for the treatment of patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and juvenile idiopathic arthritis.

Abstract
OBJECTIVE To evaluate the 2-year efficacy and safety of etanercept in patients with ankylosing spondylitis (AS). METHODS A 96-week open-label extension study, which followed a 12-week double-blind placebo-controlled trial, was designed to provide longterm efficacy and safety data, including radiographic outcomes, for patients treated with etanercept 25 mg twice weekly (NCT00421980). In all, 81 patients were enrolled (96% of the participants from the double-blind study). Key efficacy measures included improvement using the Assessment in Ankylosing Spondylitis 20% (ASAS20) criteria, the Bath Ankylosing Spondylitis Functional Index (BASFI), and the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Radiographic progression was evaluated using the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) method. Paired t tests were used to test within-group changes from baseline. RESULTS The percentage of responders, by ASAS20 criteria, remained relatively constant in patients who received etanercept during the 12-week double-blind study (60% at Week 0 and 83% at Week 96 of the open-label extension); more patients from the placebo group became responders after being switched to etanercept (23% and 74%, respectively). A similar trend was also observed using the ASAS40 and ASAS5/6 criteria, the BASFI, and the BASDAI. Most patients had no change from baseline in mSASSS values. Etanercept was well tolerated; the most frequent adverse events were injection site reactions (n=30; 37.0%) and headache (n=18; 22.2%), and the most frequent infections were upper respiratory tract infections (n=43; 53.1%) and flu syndrome (n=22; 27.2%). CONCLUSION For 2 years, etanercept was clinically effective and well tolerated, with no unexpected safety findings.

Abstract
Objective.To evaluate the safety and efficacy of abatacept plus methotrexate (MTX) over 5 years in patients with rheumatoid arthritis.Methods.Patients were randomized to abatacept 10 or 2 mg/kg or placebo, plus MTX. Patients completing the 1-year, double-blind period entered the longterm extension, where all patients received a fixed dose of abatacept ~10 mg/kg. We describe safety analyses for all patients who received at least 1 dose of abatacept and efficacy analyses for the original ~10 mg/kg abatacept-treated group, over 5 years.Results.Of the 235 abatacept- or placebo-treated patients completing the double-blind period, 219 entered the longterm extension; 130 (59.4%) were continuing at Year 5. No unexpected safety events were observed during the longterm extension compared with the double-blind period. Incidence rates of adverse events (AE) and serious AE were 489.7 and 20.0/100 patient-years in Year 1 versus 374.9 and 18.9/100 patient-years in the cumulative period, respectively. Using exploratory analyses, improvements observed at Year 1 in the 10 mg/kg group were maintained at Year 5, as assessed by ACR responses (ACR20 = 77.1% vs 82.7%; ACR50 = 53.0% vs 65.4%; ACR70 = 28.9% vs 40.4% at Years 1 and 5, respectively) and disease activity (Low Disease Activity State = 48.2% vs 58.5%; Disease Activity Score-28-defined remission = 25.3% vs 45.3% at Years 1 and 5, respectively).Conclusion.Abatacept maintained the efficacy observed at Year 1 over 5 years of treatment, and demonstrated consistent safety and tolerability. These data, along with relatively high retention rates, support the longterm clinical benefit provided by selective T cell costimulation modulation. Clinical trial registry: ClinicalTrials.gov; clinical trial registration number: NCT00254293.
