Background: The phase 3 FUTURE 5 trial (NCT02404350) showed the clinical and radiographical efficacy of secukinumab in patients with psoriatic arthritis. This analysis aimed to assess the effect of secukinumab on patient-reported outcomes (PROs). Methods: FUTURE 5 was a phase 3, multicentre, parallel-group randomised trial in which patients who were 18 years old or older, met the classification criteria for psoriatic arthritis at screening, and had symptoms of moderate-to-severe psoriatic arthritis for at least 6 months were randomly assigned to receive secukinumab 300 mg, 150 mg, 150 mg no loading dose (NL), or placebo weekly from baseline to week 4 and every 4 weeks thereafter. The prespecified PROs of the FUTURE 5 trial were assessed first in the overall population. We report mean changes from baseline and the proportion of patients reporting improvements equal to or more than the minimum clinically important differences (MCIDs) and scores equal to or more than the normative values for patient global assessments (PtGA) of disease activity; psoriasis and arthritis visual analogue scale (VAS) scores; pain VAS; Health Assessment Questionnaire Disability Index (HAQ-DI); 36-item Short Form Health Survey (SF-36); Functional Assessment of Chronic Illness Therapy Fatigue (FACIT-F); and quality of life questionnaires. Patients were then stratified and assessed according to their tumour necrosis factor (TNF) inhibitor status (TNF-naive and TNF-inadequate responder [TNF-IR] populations) as a post-hoc analysis. Findings: Patients in all secukinumab groups reported significant least-squares mean changes from placebo at week 16 in all PROs except SF-36 mental component summary (MCS), irrespective of TNF inhibitor use. These included PtGA (300 mg difference vs placebo −12·2 [95% CI −16·3 to −8·1], 150 mg −8·22 [−12·4 to −4·1], 150 mg NL −8·3 [−12·5 to −4·2]; all p Interpretation: Secukinumab resulted in early, statistically significant, clinically meaningful, sustained improvements in PROs across all doses compared with placebo in patients with active psoriatic arthritis. These improvements were seen irrespective of previous TNF inhibitor use, in a post-hoc analysis. These results indicate that secukinumab provides comprehensive improvement for patients with psoriatic arthritis, regardless of previous therapy.

Objective To investigate the longer‐term effects of secukinumab 150 mg on fatigue in patients with ankylosing spondylitis (AS) in MEASURE 1 (up to 3 years) and MEASURE 2 (up to 2 years). Methods Patients with active AS were randomized to secukinumab or placebo in MEASURE 1 (10 mg/kg intravenous [IV] followed by 150 mg subcutaneous [SC]) and MEASURE 2 (150 mg SC). Patients were naive to or had an inadequate response/intolerance to tumor necrosis factor inhibitors (anti‐TNF‐naive/ anti‐TNF‐IR). Fatigue was measured using the Functional Assessment of Chronic Illness Therapy‐Fatigue (FACIT‐F) scale. Relationships between fatigue response and baseline characteristics and clinical/laboratory variables were explored. Results Significant improvements in FACIT‐F scores from baseline were observed with secukinumab across both studies versus placebo at week 16 (P < 0.05). Improvements were sustained through week 156 (MEASURE 1)/week 104 (MEASURE 2). Significantly more patients reported fatigue responses (FACIT‐F increase ≥4; observed data) with secukinumab 150 mg than placebo at week 16 in both MEASURE 1 (P < 0.05) and MEASURE 2 (P < 0.01). Fatigue responses were achieved by 75.6% of patients receiving secukinumab at week 156 (MEASURE 1) and 81.4% at week 104 (MEASURE 2); these results were consistent in both anti‐TNF‐naive (74.3% and 84.6%) and anti‐TNF‐IR (81.3% and 75.0%) patients. Baseline characteristics did not predict improvement in fatigue consistently. Fatigue responses were moderately to strongly correlated with responses in several clinical measures, including Assessment of SpondyloArthritis international Society (ASAS)20/40, ASAS5/6 responses, Ankylosing Spondylitis Disease Activity Score‐C reactive protein (ASDAS‐CRP), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and Short‐form (SF)‐36 scores. Conclusion Secukinumab provided rapid and sustained improvements in fatigue for up to 3 years, regardless of prior anti‐TNF exposure.

Elvira Bangert,1 Laura Wakani,2 Mehveen Merchant,3 Vibeke Strand,4 Zahi Touma2 1Division of Rheumatology, Department of Medicine, Queen’s University, Kingston, ON, Canada; 2University of Toronto Lupus Clinic, Toronto Western Hospital, Centre for Prognosis Studies in the Rheumatic Diseases, Toronto, ON, Canada; 3Division of Rheumatology, Nova Scotia Health Authority, Dalhousie University, Halifax, NS, Canada; 4Division of Immunology/Rheumatology, Stanford University, Palo Alto, CA, USA Abstract: Systemic lupus erythematosus (SLE) is a chronic autoimmune, multisystem rheumatic disease with significant impact on health-related quality of life (HRQoL). Patient-reported outcomes (PROs) provide valuable data on patient perceptions across a variety of domains, such as HRQoL, pain, fatigue, and depression. The measurement and results of PROs with respect to HRQoL in randomized controlled trials (RCTs) on belimumab (B-lymphocyte stimulator inhibitor) in SLE are reviewed here, including BLISS-52 and BLISS-76, as well as publications related to belimumab trials that included HRQoL data. Other trials that evaluated belimumab did not include HRQoL data and were therefore not included in the analysis. The BLISS-52 and BLISS-76 RCTs met their primary endpoints and demonstrated improvements in PROs, measured by the 36-item Short Form Health Survey, EuroQol 5 Dimensions, and Functional Assessment of Chronic Illness Therapy-Fatigue Scale. Belimumab was shown overall to improve PROs in adult autoantibody-positive lupus patients. Keywords: quality of life, fatigue, systemic lupus, Benlysta, trials

Secukinumab has demonstrated sustained improvement in the signs and symptoms of psoriatic arthritis (PsA) over 2 years in the FUTURE 2 study (NCT01752634). This post hoc analysis assessed the ability of secukinumab to achieve Psoriatic Arthritis Disease Activity Score (PASDAS)-based remission or low disease activity (LDA) through 2 years among patients with PsA in the FUTURE 2 study. PASDAS (cut-off scores: remission ≤ 1.9; LDA > 1.9 and

ObjectiveTofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). Here we present data from the completed Phase 3 randomised controlled trial (RCT) ORAL Scan (NCT00847613), which evaluated the impact of tofacitinib on patient-reported outcomes (PROs) through 24 months in patients with active RA and inadequate responses to methotrexate (MTX-IR).MethodsPatients were randomised 4:4:1:1 to receive tofacitinib 5 or 10 mg twice daily (BID), or placebo advanced to tofacitinib 5 or 10 mg, plus background MTX. Patients receiving placebo advanced to tofacitinib at month 3 (non-responders) or month 6 (remaining patients). Mean changes from baseline in PROs, assessed at months 1-24, included Health Assessment Questionnaire-Disability Index, Patient Global Assessment of disease activity (visual analogue scale [VAS]), Patient Assessment of Arthritis Pain (VAS), health-related quality of life (Short Form-36 version 2), Functional Assessment of Chronic Illness Therapy-Fatigue and Medical Outcomes Study-Sleep.ResultsOverall, 539/797 ( 67.6%) patients completed 24 months' treatment. At month 3, tofacitinib-treated patients reported significant (p

Objective: Outcome Measures in Rheumatology (OMERACT) convened a premeeting in 2018 to bring together patients, regulators, researchers, clinicians, and consumers to build upon previous OMERACT drug safety work, with patients fully engaged throughout all phases. Methods: Day 1 included a brief introduction to the history of OMERACT and methodology, and an overview of current efforts within and outside OMERACT to identify patient-reported medication safety concerns. On Day 2, two working groups presented results; after each, breakout groups were assembled to discuss findings. Results: Five themes pertaining to drug safety measurement emerged. Conclusion: Current approaches have failed to include data from the patient’s perspective. A better understanding of how individuals with rheumatic diseases view potential benefits and harms of therapies is essential.

Objective.The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and Outcome Measures in Rheumatology (OMERACT) psoriatic arthritis (PsA) working group is developing a Core Outcome Measurement Set for PsA clinical trials [randomized controlled trials (RCT) and longitudinal observational studies (LOS)] using the OMERACT Filter 2.1 instrument selection algorithm. Our objective was to assess the Psoriatic Arthritis Impact of Disease questionnaire (PsAID12) for the measurement of the core domain PsA-specific health-related quality of life (HRQOL).Methods.PsAID12 measurement property evidence gathered in a systematic literature review, and additional analyses conducted in LOS, were used to inform a consensus process. Analyses that had not been published were independently reviewed by the OMERACT technical advisory group. Data and process were presented, discussed in breakout groups, and voted on at the OMERACT conference (Terrigal, Australia, May 2018).Results.PsAID12 fulfilled the green (good to go) OMERACT standards for domain match, feasibility, reliability, and construct/longitudinal construct validity. Discrimination and thresholds of meaning were amber (caution but good enough to go forward). The overall working group recommendation was amber/provisional endorsement of PsAID12 for measuring PsA-specific HRQOL in RCT and LOS. Of 96 participants who voted at the PsA OMERACT workshop, 87.5% (84) voted “yes” to endorse this recommendation; 14 of the 96 were patient research partners (PRP) and 93% of them (13) voted “yes”; 82 participants were not PRP and 87% of them (71) voted “yes.”Conclusion.At OMERACT 2018, PsAID12 was the first patient-reported outcome measure provisionally endorsed as a core outcome measure for disease-specific HRQOL in PsA clinical trials. PsAID12 discrimination and improvement thresholds will be studied in future RCT.

Objective.The Contextual Factors Working Group aims to provide guidance on addressing contextual factors in rheumatology trials within OMERACT.Methods.During the Special Interest Group session at OMERACT 2018, preliminary results were presented from a case scenario survey and semistructured interviews, including contextual factors mentioned in these. A group-based exercise sought to identify and rank important generic contextual factors.Results.A total of 79 candidate factors were listed. Across the 3 groups, gender/sex, comorbidities, and the healthcare system were ranked as most important.Conclusion.The identified important contextual factor domains may be considered a provisional list pending further research.

Background: An updated psoriatic arthritis (PsA) core outcome set (COS) for randomized controlled trials (RCTs) was endorsed at the Outcome Measures in Rheumatology (OMERACT) meeting in 2016. Objectives: To synthesize the evidence on measurement properties of patient reported outcome measures (PROMs) for PsA and thereby contribute to development of a PsA core outcome measurement set (COMS) as described by the OMERACT Filter 2.0. Methods: A systematic literature search was performed in EMBASE, MEDLINE and PsycINFO on Jan 1, 2017 to identify full-text articles with an aim of assessing the measurement properties of PROMs in PsA. Two independent reviewers rated the quality of studies using the COnsensus based standards for the Selection of health Measurement INstruments (COSMIN) checklist, and performed a qualitative evidence synthesis. Results: Fifty-five studies were included in the systematic review. Forty-four instruments and a total of 89 scales were analyzed. PROMs measuring COS domains with at least fair quality evidence for good validity and reliability (and no evidence for poor properties) included the Stockerau Activity Score for PsA (German), Psoriasis Symptom Inventory, visual analogue scale for Patient Global, 36 Item Short Form Health Survey Physical Function subscale, Health Assessment Questionnaire Disability Index, Bath Ankylosing Spondylitis Functional Index, PsA Impact of Disease questionnaire, PsA Quality of Life questionnaire, VITACORA-19, Functional Assessment of Chronic Illness Therapy Fatigue scale and Social Role Participation Questionnaire. Conclusions: At least one PROM with some evidence for aspects of validity and reliability was available for six of the eight mandatory domains of the PsA COS.

Objective: To evaluate the efficacy, biological activity and safety of tregalizumab in patients with active rheumatoid arthritis (RA) and an inadequate response to methotrexate (MTX). Methods: 321 patients were randomised (1:1:1:1) to placebo or tregalizumab 25, 100 or 200 mg once-weekly subcutaneously in addition to MTX treatment. Responders at week 12 continued the same treatment, and non-responders at week 12 were escalated to the next higher tregalizumab dose level or re-randomised from placebo to active treatment. After 24 weeks, patients could continue treatment with tregalizumab for 24 weeks (extension phase). The primary endpoint was the American College of Rheumatology 20% improvement criteria (ACR20) response rate at week 12. Safety and biological activity were monitored through week 48. Results: At week 12, ACR20 response rates were not statistically significantly different between placebo and any of the tregalizumab doses. Tregalizumab injections were well tolerated; most adverse events were mild to moderate and comparable among treatment and placebo groups. Biological activity was shown by dose-dependent CD4 downmodulation. Conclusion: Treatment with tregalizumab did not show significant clinical efficacy in patients with active RA compared with placebo but resulted in the expected biological effect on CD4 modulation. Tregalizumab was generally well tolerated, and no new safety findings were identified.

Background: Cardiovascular disease is a major comorbidity of rheumatoid arthritis (RA) and a leading cause of death. Chronic systemic inflammation involving tumour necrosis factor alpha (TNF) could contribute to endothelial activation and atherogenesis. A number of anti-TNF therapies are in current use for the treatment of RA, including certolizumab pegol (CZP), (Cimzia ®; UCB, Belgium). Anti-TNF therapy has been associated with reduced clinical cardiovascular disease risk and ameliorated vascular function in RA patients. However, the specific effects of TNF inhibitors on endothelial cell function are largely unknown. Our aim was to investigate the mechanisms underpinning CZP effects on TNF-activated human endothelial cells. Methods: Human aortic endothelial cells (HAoECs) were cultured in vitro and exposed to a) TNF alone, b) TNF plus CZP, or c) neither agent. Microarray analysis was used to examine the transcriptional profile of cells treated for 6 hrs and quantitative polymerase chain reaction (qPCR) analysed gene expression at 1, 3, 6 and 24 hrs. NF-κB localization and IκB degradation were investigated using immunocytochemistry, high content analysis and western blotting. Flow cytometry was conducted to detect microparticle release from HAoECs. Results: Transcriptional profiling revealed that while TNF alone had strong effects on endothelial gene expression, TNF and CZP in combination produced a global gene expression pattern similar to untreated control. The two most highly up-regulated genes in response to TNF treatment were adhesion molecules E-selectin and VCAM-1 (q < 0.00005). This was supported by qPCR analysis at 6 hrs (E-selectin and VCAM-1; 208.5 fold and 40.5, respectively above control) and also at 1, 3 and 24 hrs (E-selectin; 25.6, 93.5, 12.7 fold, respectively) (VCAM-1; 4.7, 47.2, 17.6 fold) (n = 3; p < 0.05). In contrast, HAoECs treated with TNF in combination with CZP exhibited control levels of E-selectin and VCAM-1 transcript (p > 0.2 compared to control; p > 0.05 compared to TNF alone). The NF-κB pathway was confirmed as a downstream target of TNF-induced HAoEC activation, via nuclear translocation of NF-κB and degradation of IκB, effects which were abolished by treatment with CZP. In addition, flow cytometry detected an increased production of endothelial microparticles in TNF-activated HAoECs, which was prevented by treatment with CZP. Conclusions: We have found at a cellular level that a clinically available TNF inhibitor, CZP reduces the expression of adhesion molecule expression, and prevents TNF-induced activation of the NF-κB pathway. Furthermore, CZP prevents the production of microparticles by activated endothelial cells. This could be central to the prevention of inflammatory environments underlying these conditions and measurement of microparticles has potential as a novel prognostic marker for future cardiovascular events in this patient group.

OBJECTIVES: To establish if using intensive treatment to reduce synovitis and attain remission in active rheumatoid arthritis (RA) improves all aspects of health-related quality of life (HRQoL).METHODS: A secondary analysis of two randomised clinical trials (CARDERA and TACIT) was undertaken. CARDERA randomised 467 patients with early active RA to different disease-modifying antirheumatic drug (DMARD) regimens, including high-dose tapering corticosteroids. TACIT randomised 205 established patients with active RA to combination DMARDs (cDMARDs) or tumour necrosis factor-α inhibitors (TNFis). Short-Form 36 (SF-36) measured HRQoL across eight domains, generating physical (PCS) and mental (MCS) component summary scores. Linear regression evaluated 6-month intensive treatment impacts. Mean SF-36 scores, stratified by end point disease activity category, were compared with age/gender-matched population scores.RESULTS: In CARDERA, intensive corticosteroid treatment gave significantly greater improvements in PCS but not MCS scores relative to placebo. In TACIT, all eight SF-36 domains had improvements from baseline exceeding minimal clinically important differences with cDMARDs and TNFis. Significantly greater improvements with TNFi relative to cDMARDs were reported in PCS only (p=0.034), after adjusting for covariates. Remission provided the best SF-36 profiles, but scores in physical functioning, role physical and general health in both trials remained below normative values. Patient global assessment of disease activity had a greater association with HRQoL than other disease activity score (DAS28) components.CONCLUSIONS: Intensive corticosteroid treatment in early RA improves physical but not mental health, relative to placebo. In established RA, cDMARDs and TNFi provide similar improvements in HRQoL. As remission optimises but fails to normalise HRQoL, a focus on treatment strategies targeting HRQoL is required.TRIAL REGISTRATION NUMBERS: CARDERA was registered as ISRCTN 32484878. TACIT was registered as ISRCTN 37438295; pre-results.

The GRAPPA-OMERACT psoriatic arthritis (PsA) working group is in the process of updating the PsA core domain set to improve and standardize the measurement of PsA outcomes. Work streams comprise literature reviews of domains and outcome measurement instruments, an international qualitative research project with PsA patients to generate domains important to patients, outcome measurement instrument assessment, conduct of domain consensus panels with patients and physicians, and evidence-based selection of instruments. Patient research partners are involved in each of the projects. The working group will present findings and seek endorsement for the new PsA core domain set, outcome measurement set, and research agenda at the OMERACT meeting in May 2016.

Introduction: Psoriatic arthritis (PsA) has a significant negative impact on patients’ (pts) health-related quality of life (HRQoL). Secukinumab improved the signs and symptoms of active PsA in the randomized, double-blind, placebo (PBO)-controlled phase 3 FUTURE 2 study (NCT01752634) [ref:1].[for full text, please go to the a.m. URL], 43.

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). Here we investigated the effects of tofacitinib on patient-reported outcomes (PRO) in patients with active RA.Two, 6-month, double-blind, placebo-controlled Phase 2b studies were performed. The combination study evaluated patients with inadequate response to methotrexate who received tofacitinib 1-15 mg twice daily (BID), 20 mg once daily or placebo, on background methotrexate. In the monotherapy study, patients with inadequate response to disease-modifying anti-rheumatic drugs received tofacitinib 1-15 mg BID, adalimumab 40 mg once every other week or placebo. PROs measured were: Patient's Assessment of Arthritis Pain (PAAP), Patient's Assessment of Disease Activity, HAQ-DI, FACIT-F and SF-36.In the combination study (n=507), significant improvements (p0.05) versus placebo were observed at Week 12 in PAAP (visual analogue scale) and HAQ-DI for all tofacitinib groups. In the monotherapy study (n=384), significant improvements in PAAP were observed at Week 12 for tofacitinib 5, 10 and 15 mg BID, and in HAQ-DI for tofacitinib 3, 5, 10 and 15 mg BID. Significant improvements versus placebo were seen at Week 2 in PAAP (both studies) and HAQ‑DI (monotherapy study) with tofacitinib, and were maintained throughout each study. In both studies, improvements in several domains of the SF-36 in the tofacitinib groups were observed at Weeks 12 and 24.In patients with active RA, tofacitinib, either in combination with methotrexate or as monotherapy, demonstrated rapid and sustained improvement in pain, physical functioning and health-related quality of life.

Interstitial lung diseases (ILD), including those related to connective tissue disease (CTD), and idiopathic pulmonary fibrosis (IPF) carry high morbidity and mortality. Great efforts are under way to develop and investigate meaningful treatments in the context of clinical trials. However, efforts have been challenged by a lack of validated outcome measures and by inconsistent use of measures in clinical trials. Lack of consensus has fragmented effective use of strategies in CTD-ILD and IPF, with a history of resultant difficulties in obtaining agency approval of treatment interventions. Until recently, the patient perspective to determine domains and outcome measures in CTD-ILD and IPF had never been applied. Efforts described here demonstrate unequivocally the value and influence of patient involvement on core set development. Regarding CTD-ILD, this is the first OMERACT working group to directly address a manifestation/comorbidity of a rheumatic disease (ILD) as well as a disease not considered rheumatic (IPF). The OMERACT 11 proceedings of the CTD-ILD Working Group describe the forward and lateral process to include both the medical and patient perspectives in the urgently needed identification of a core set of preliminary domains and outcome measures in CTD-ILD and IPF.

Rationale: Clinical trial design in interstitial lung diseases (ILDs) has been hampered by lack of consensus on appropriate outcome measures for reliably assessing treatment response. In the setting of connective tissue diseases (CTDs), some measures of ILD disease activity and severity may be confounded by non-pulmonary comorbidities. Methods: The Connective Tissue Disease associated Interstitial Lung Disease (CTD-ILD) working group of Outcome Measures in Rheumatology-a non-profit international organisation dedicated to consensus methodology in identification of outcome measures-conducted a series of investigations which included a Delphi process including >248 ILD medical experts as well as patient focus groups culminating in a nominal group panel of ILD experts and patients. The goal was to define and develop a consensus on the status of outcome measure candidates for use in randomised controlled trials in CTD-ILD and idiopathic pulmonary fibrosis (IPF). Results: A core set comprising specific measures in the domains of lung physiology, lung imaging, survival, dyspnoea, cough and health-related quality of life is proposed as appropriate for consideration for use in a hypothetical 1-year multicentre clinical trial for either CTD-ILD or IPF. As many widely used instruments were found to lack full validation, an agenda for future research is proposed. Conclusion: Identification of consensus preliminary domains and instruments to measure them was attained and is a major advance anticipated to facilitate multicentre RCTs in the field.

Objective: To develop a provisional core set of response measures for clinical trials of systemic sclerosis (SSc). Methods: The Scleroderma Clinical Trials Consortium (SCTC) conducted a structured, 3-round Delphi exercise to reach consensus on a core set of measures for clinical trials of SSc. Round 1 asked the SCTC investigators to list items in 11 pre-defined domains (skin, musculoskeletal, cardiac, pulmonary, cardio-pulmonary, gastrointestinal, renal, Raynaud phenomenon and digital ulcers, health-related quality of life and function, global health, and biomarkers) for SSc clinical trials. Round 2 asked respondents to rate the importance of the chosen items and was followed by a meeting, during which the Steering Committee discussed the feasibility, reliability, redundancy and validity of the items. Round 3 sought to obtain broader consensus on the core set measures. Members also voted on items that had data on feasibility but lacked data on reliability and validity, but may still be useful research outcome measures for future trials. Results: A total of 50 SCTC investigators participated in round 1, providing 212 unique items for the 11 domains. In all, 46 (92%) participants responded in round 2 and rated 177 items. The ratings of 177 items were reviewed by the Steering Committee and 31 items from the 11 domains were judged to be appropriate for inclusion in a 1-year multi-centre clinical trial. In total, 40 SCTC investigators completed round 3 and ranked 30 of 31 items as acceptable for inclusion in the core set. The Steering Committee also proposed 14 items for a research agenda. Conclusion: Using a Delphi exercise, we have developed a provisional core set of measures for assessment of disease activity and severity in clinical trials of SSc.

The American College of Rheumatology (ACR) hybrid (a modified mean percent response to treatment) was officially recommended by the ACR as a revision to 20%, 50%, and 70% response criteria (ACR20/50/70) scores, but has not been tested in clinical trials. We performed a post hoc analysis of a phase III study of certolizumab pegol (Rheumatoid Arthritis Prevention of Structural Damage 1 [RAPID 1]) using the ACR hybrid.Patients with active rheumatoid arthritis were randomized to certolizumab pegol (200 mg or 400 mg every other week) plus methotrexate or placebo plus methotrexate. ACR hybrid scores were compared with ACR20/50/70 outcomes.Differences between active treatment and placebo were significant throughout the study using the ACR20 and ACR hybrid outcomes. In the certolizumab pegol 200 mg group, the median ACR hybrid score at week 52 (last observation carried forward) was 49.99. A total of 258 (65.8%) of 392 and 172 (43.9%) of 392 patients had ACR20 and ACR50 responses, respectively. An additional 55 patients (14.0%) and 59 patients (15.1%) had mean improvements in ACR core measures of ≥ 20% and ≥ 50%, respectively, and therefore had positive ACR hybrid scores, despite lacking ACR20 and ACR50 responses, respectively. In the placebo group, median ACR hybrid scores were10 at most time points; unlike other measures, the ACR hybrid measure indicated worsening scores for many patients.ACR hybrid analysis had greater sensitivity than traditional ACR20/50/70 criteria, demonstrating improvements in ACR20 nonresponders treated with certolizumab pegol. Negligible benefit was observed with placebo using ACR hybrid analysis.

Computer-based methods of measuring joint space width (JSW) could potentially have advantages over scoring joint space narrowing, with regard to increased standardization, sensitivity, and reproducibility. In an early exercise, 4 different methods showed good agreement on measured change in JSW over time in the small joints of the hands and feet. Despite differences in measurement values between methods, measurement of within-joint change over time showed no systematic differences. The within-method variation was small, with intra-operator variation being smaller than inter-operator variation. Although this initial study was limited in terms of the number of patients and timepoints (total 10), the number of joints was relatively high (340 joints), so the results were considered strong evidence supporting the validity of computer-based JSW measurements to continue the study of the potential value of JSW by comparison of measurements to manual scoring of joint space narrowing using the COBRA trial images.

Item does not contain fulltext The OMERACT 6 Minimal Clinically Important Difference/Low Disease Activity Workshop was organized with the aim of meeting the many challenges that exist in determining a low disease activity in rheumatoid arthritis (RA). This article presents an overview of that workshop, including results of the voting, a summary of associated discussions, recommendations, and a proposed research agenda.

Objective. To assess the safety and effectiveness of leflunomide versus placebo in patients with active rheumatoid arthritis (RA) treated for 6 months. Methods. Four hundred two patients were randomly assigned to receive placebo or leflunomide at 5 mg, 10 mg, or 25 mg daily, A washout period of 6-12 weeks from prior second-line therapy was required. Results. Statistically significant improvement in primary and secondary outcome measures, as well as by responder analyses, occurred in the 10-mg and 25-mg dosage groups compared to placebo. Twenty-one patients (7.0%) in the active treatment groups withdrew due to adverse events (AEs). The incidence of AEs was higher with leflunomide than with placebo, Gastrointestinal symptoms, weight loss, allergic reactions, skin rash, and reversible alopecia were more common in the 10-mg and 25- mg dosage groups, The incidence of infections was similar between the treatment and placebo groups ; no opportunistic infections were seen, Transient elevations in liver function studies were noted in a small number of patients. Conclusion. Leflunomide is effective in daily doses of 10 mg and 25 mg in patients with active RA, Improved efficacy at the 25-mg dose was associated with a higher incidence of AEs, Randomized, placebo-controlled trials using daily doses of 10 mg and 20 mg are under way in the US and Europe to confirm these positive results.

Item does not contain fulltext The MCID (minimal clinically important difference) module of OMERACT 5 developed a research agenda that led to the conclusion that a state of low disease activity for rheumatoid arthritis (RA) would need to be defined. To develop such a definition the various concepts and terminologies, the process for developing an operational definition, and the availability and design of longitudinal datasets for validation needed to be considered. This article describes the process of the MCID/Low Disease Activity State Workshop at OMERACT 6 to develop such a definition.

Efficacy and safety of leflunomide in the treatment of patients with rheumatoid arthritis
