- OBJECTIVES: To explore 6-month and 12-month secukinumab effectiveness in patients with axial spondyloarthritis (axSpA) overall, as well as across (1) number of previous biologic/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs), (2) time since diagnosis and (3) different European registries. METHODS: Real-life data from 13 European registries participating in the European Spondyloarthritis Research Collaboration Network were pooled. Kaplan-Meier with log-rank test, Cox regression, χ² and logistic regression analyses were performed to assess 6-month and 12-month secukinumab retention, inactive disease/low-disease-activity states (Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) <2/<4, Ankylosing Spondylitis Disease Activity Score (ASDAS) <1.3/<2.1) and response rates (BASDAI50, Assessment of Spondyloarthritis International Society (ASAS) 20/40, ASDAS clinically important improvement (ASDAS-CII) and ASDAS major improvement (ASDAS-MI)). RESULTS: We included 1860 patients initiating secukinumab as part of routine care. Overall 6-month/12-month secukinumab retention rates were 82%/72%, with significant (p<0.001) differences between the registries (6-month: 70-93%, 12-month: 53-86%) and across number of previous b/tsDMARDs (b/tsDMARD-naïve: 90%/73%, 1 prior b/tsDMARD: 83%/73%, ≥2 prior b/tsDMARDs: 78%/66%). Overall 6-month/12-month BASDAI<4 were observed in 51%/51%, ASDAS<1.3 in 9%/11%, BASDAI50 in 53%/47%, ASAS40 in 28%/22%, ASDAS-CII in 49%/46% and ASDAS-MI in 25%/26% of the patients. All rates differed significantly across number of previous b/tsDMARDs, were numerically higher for b/tsDMARD-naïve patients and varied significantly across registries. Overall, time since diagnosis was not associated with secukinumab effectiveness. CONCLUSIONS: In this study of 1860 patients from 13 European countries, we present the first comprehensive real-life data on effectiveness of secukinumab in patients with axSpA. Overall, secukinumab retention rates after 6 and 12 months of treatment were high. Secukinumab effectiveness was consistently better for bionaïve patients, independent of time since diagnosis and differed across the European countries. © Author(s) (or their employer(s)) 2020.

- Background: Comedication with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) during treatment with tumour necrosis factor inhibitors (TNFi) is extensively used in psoriatic arthritis (PsA), although the additive benefit remains unclear. We aimed to compare treatment outcomes in patients with PsA treated with TNFi and csDMARD comedication versus TNFi monotherapy. Methods: Patients with PsA from 13 European countries who initiated a first TNFi in 2006-2017 were included. Country-specific comparisons of 1 year TNFi retention were performed by csDMARD comedication status, together with HRs for TNFi discontinuation (comedication vs monotherapy), adjusted for age, sex, calendar year, disease duration and Disease Activity Score with 28 joints (DAS28). Adjusted ORs of clinical remission (based on DAS28) at 12 months were calculated. Between-country heterogeneity was assessed using random-effect meta-analyses, combined results were presented when heterogeneity was not significant. Secondary analyses stratified according to TNFi subtype (adalimumab/infliximab/etanercept) and restricted to methotrexate as comedication were performed. Results: In total, 15 332 patients were included (62% comedication, 38% monotherapy). TNFi retention varied across countries, with significant heterogeneity precluding a combined estimate. Comedication was associated with better remission rates, pooled OR 1.25 (1.12-1.41). Methotrexate comedication was associated with improved remission for adalimumab (OR 1.45 (1.23-1.72)) and infliximab (OR 1.55 (1.21-1.98)) and improved retention for infliximab. No effect of comedication was demonstrated for etanercept. Conclusion: This large observational study suggests that, as used in clinical practice, csDMARD and TNFi comedication are associated with improved remission rates, and specifically, comedication with methotrexate increases remission rates for both adalimumab and infliximab. © Author(s) (or their employer(s)) 2021.

- Bien que les mesures de teneur en eau soient largement utilisées dans l'industrie, les considérations métrologiques quant à cette mesure ne sont pas complètement abouties de sorte à fournir des mesures fiables et traçables au SI. Afin de remédier à ceci, le projet de recherche conjoint, Joint Research Project SIB64 “METefnet – Metrology for moisture in materials”, est actuellement en cours, et contribue au programme européen de recherche en métrologie European Metrology Research Programme. Le projet METefnet a pour objectifs de développer et d'améliorer l'approche métrologique de ce sujet. Ceci inclus notamment: le travail sur de nouvelles méthodes de référence pour évaluer la fraction massique en eau, l'amélioration des mesures mettant en œuvre la méthode primaire de type titration Karl Fischer, le développement de nouveaux matériaux de référence certifiés présentant une très bonne stabilité et permettant une traçabilité au SI, le développement de nouveaux étalons de transfert, la réalisation d'études visant à quantifier et réduire les effets liés à la prise d'échantillon, son transport et sa manipulation, le développement d'une nouvelle méthode pour étalonner les instruments mesurant l'humidité de surface, et l'amélioration des méthodes d'estimation d'incertitudes de ces mesures. Ce travail, réalisé dans le domaine de la métrologie de l'humidité au sein des matériaux, couvre à la fois le mesurande décrit comme étant spécifiquement la teneur en eau, seule, dans les matériaux, mais également un mesurande plus large pouvant inclure l'eau ainsi que d'autres liquides ou composés organiques volatiles; ceci afin de bien mettre en exergue la différence qui peut être observée entre ces deux mesurandes. Le projet global a pour objectif de soutenir une action de dissémination et de traçabilité au système SI des mesures de teneur en eau dans les matériaux avec une exactitude optimale et de développer une infrastructure métrologique cohérente pour ce type de mesures. Le travail technique ainsi que les dernières avancées vous sont ainsi présentées.

- Objectives: In patients with axial spondyloarthritis (axSpA) initiating their first tumor necrosis factor alpha-inhibitor (TNFi), we aimed to identify common baseline predictors of Ankylosing Spondylitis Disease Activity Score (ASDAS-CRP) inactive disease (primary objective) and clinically important improvement (CII) at 6 months, and drug retention at 12-months across 15 European registries. Methods: Baseline demographic and clinical characteristics were collected. Outcomes were investigated per registry and in pooled data using logistic regression analyses on multiply imputed data. Results: The consistency of baseline predictors in individual registries justified pooling the data. In the pooled dataset (n = 21,196), the 6-month rates for ASDAS inactive disease and ASDAS CII were 26% and 51%, and the 12-month drug retention rate 65% in patients with available data (n = 9,845, n = 6,948 and n = 21,196, respectively). Nine common baseline predictors of ASDAS inactive disease, ASDAS CII and 12-month drug retention were identified, and the odds ratios (95%-confidence interval) for ASDAS inactive disease were: age, per year: 0.97 (0.97–0.98), men vs. women: 1.88 (1.60–2.22), current vs. non-smoking: 0.76 (0.63–0.91), HLA-B27 positive vs. negative: 1.51 (1.20–1.91), TNF start year 2015–2018 vs. 2009–2014: 1.24 (1.06–1.45), CRP>10 vs. ≤10 mg/l: 1.49 (1.25–1.77), one unit increase in health assessment questionnaire (HAQ): 0.77 (0.58–1.03), one-millimeter (mm) increase in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) fatigue and spinal pain: 0.99 (0.99–1.00) and 0.99 (0.99–1.99), respectively Conclusion: Common baseline predictors of treatment response and adherence to TNFi could be identified across data from 15 European registries, indicating that they may be universal across different axSpA populations.

- Background: Rheumatoid arthritis is a chronic inflammatory disease with a well-recognised female preponderance. In this post-hoc analysis of the NORD-STAR trial, we aimed to examine sex differences in remission rates with three different biological treatments combined with methotrexate versus active conventional treatment over 24 weeks, in patients with early rheumatoid arthritis. Methods: NORD-STAR was a multicentre, investigator-initiated, assessor-blinded, phase 4, randomised, controlled trial of early rheumatoid arthritis, done in Denmark, Finland, Iceland, Norway, Sweden, and the Netherlands. Newly diagnosed patients, naive to disease-modifying antirheumatic drugs, aged 18 years or older with early rheumatoid arthritis and with a symptom duration less than 24 months were randomly assigned (1:1:1:1) to receive active conventional treatment, certolizumab-pegol, abatacept, or tocilizumab. Sex was reported in case report forms by study physicians or by study nurses. Data on gender were not collected. Remission outcomes were analysed with logistic generalised estimating equations (GEE), using a logit link and exchangeable correlation matrix. The model included treatment, time, sex, and the relevant interactions. For this post-hoc analysis, the co-primary outcomes were differences in Clinical Disease Activity Index (CDAI) remission (CDAI score ≤2·8) between sexes over time and at week 24, assessed with interaction terms (men vs women within each treatment comparison) and using active conventional treatment as the reference. We present adjusted average marginal differences in remission rates (risk differences) with 95% CIs. Findings: Between Dec 14, 2012, and Dec 11, 2018, 812 patients were enrolled and randomly assigned; 217 received active conventional treatment, 203 received certolizumab-pegol, 204 received abatacept, and 188 received tocilizumab. All 812 patients were included in this analysis; 561 (69%) were women and 251 (31%) were men. Observed CDAI remission rates at 24 weeks were numerically higher among men than among women despite comparable disease activity at baseline (55% vs 50% with active conventional treatment, 57% vs 52% with certolizumab-pegol, 65% vs 51% with abatacept, and 61% vs 40% with tocilizumab). In the adjusted analysis, with active conventional treatment as the reference, the only significant difference between men and women was in the tocilizumab group (pinteraction=0·015); men in the tocilizumab group had a higher probability of CDAI remission, on average over time, than did men in the active conventional treatment group (0·12; 95% CI 0·00 to 0·23), whereas women in the tocilizumab group had a lower probability of remission than did women in the active conventional treatment group (–0·05, 95% CI –0·13 to 0·02). Interpretation: Numerically higher remission rates were observed in men than in women in all four treatment groups at week 24, suggesting that this generalised sex difference is not related to the treatment. The difference between men and women was significantly greater with tocilizumab, an interleukin (IL)-6 inhibitor, than with active conventional treatment, suggesting a possible additional sex-based effect specific for IL-6 blockade.

- Objective: Galectin-3 (Gal-3) has been suggested as a proinflammatory mediator in rheumatoid arthritis (RA). We aimed to study clinical and pathogenic aspects of Gal-3 in RA. Method: Plasma samples from healthy controls (n = 48) and patients with newly diagnosed, early RA were assayed for soluble Gal-3. In patients with chronic RA (n = 18), Gal-3 was measured in both plasma and synovial fluid. Synovial fluid mononuclear cells were used to purify fibroblast-like synoviocytes (FLSs) and osteoclasts. Monocultures of FLSs and autologous co-cultures of FLSs and peripheral blood mononuclear cells were established and co-incubated with a Gal-3 inhibitor. Results: Patients with early and chronic RA had persistently increased plasma levels of Gal-3 compared with controls. However, changes in plasma Gal-3 at the level of individuals were associated with long-term disease activity. In seropositive early RA patients, all patients with decreasing plasma Gal-3 from 0 to 3 months had low disease activity after 2 years (p < 0.05). Gal-3 levels in synovial fluid were markedly elevated. In vitro, co-incubation with a Gal-3 inhibitor (GB1107, 10 µM) led to a significant reduction in both interleukin-1β and tumour necrosis factor-α secretion from FLS monocultures (both p < 0.05) and decreased monocyte-derived osteoclastogenesis compared with controls (both p < 0.05). Conclusions: Our findings underscore the role of Gal-3 regarding disease activity and tissue destruction in RA. An initial decrease in plasma Gal-3 levels predicted decreased long-term disease activity. Correspondingly, a Gal-3 inhibitor decreased the activity of inflammatory FLSs and osteoclastogenesis in patients with RA.

- Background: New targeted therapies and improved treatment strategies have dramatically improved the outcomes of patients with rheumatoid arthritis (RA). However, it is unknown whether different early aggressive interventions can induce stable remission or a low-active disease state that can be maintained with conventional synthetic disease-modifying antirheumatic drug (csDMARD) therapy, and whether they differ in efficacy and safety. The Nordic Rheumatic Diseases Strategy Trials And Registries (NORD-STAR) study will assess and compare (1) the proportion of patients who achieve remission in a head-to-head comparison between csDMARD plus glucocorticoid therapy and three different biological DMARD (bDMARD) therapies with different modes of action and (2) two de-escalation strategies in patients who respond to first-line therapy. Methods/design: In a pragmatic, 80-160-week, multicenter, randomized, open-label, assessor-blinded, phase 4 study, 800 patients with early RA (symptom duration less than 24 months) are randomized 1:1:1:1 to one of four different treatment arms: (1) aggressive csDMARD therapy with methotrexate + sulphasalazine + hydroxychloroquine + i.a. glucocorticoids (arm 1A) or methotrexate + prednisolone p.o. (arm 1B), (2) methotrexate + certolizumab-pegol, (3) methotrexate + abatacept, or (4) methotrexate + tocilizumab. The primary clinical endpoint is the proportion of patients reaching Clinical Disease Activity Index (CDAI) remission at week 24. Patients in stable remission over 24 consecutive weeks enter part 2 of the study earliest after 48 weeks. Patients not achieving sustained CDAI remission over 24 consecutive weeks, exit the study after 80 weeks. In part 2, patients are re-randomized to two different de-escalation strategies, either immediate or delayed (after 24 weeks) tapering, followed by cessation of study medication. All patients remain on stable doses of methotrexate. The primary clinical endpoint in part 2 is the proportion of patients in remission (CDAI ≤2.8) 24 weeks after initiating treatment de-escalation. Radiographic assessment will be performed regularly throughout the trial, and blood and urine samples will be stored in a biobank for later biomarker analyses. Discussion: NORD-STAR is the first investigator-initiated, randomized, early RA trial to compare (1) csDMARD and three different bDMARD therapies head to head and (2) two different de-escalation strategies. The trial has the potential to identify which treatment strategy to apply in early RA to achieve the best possible outcomes for both patients and society.
