Standardized reporting for systematic global evaluation of axial spondyloarthritis: An evidence-based and consensus-driven initiative.

INTRODUCTION: National and international scientific societies advocate for a regular, systematic, and standardized global evaluation of axial spondyloarthritis (axSpA) patients. However, there are no recommendations specifying the content of this global evaluation. This initiative aimed to propose a standardized reporting framework, using evidence-based and consensus approaches, to collect data on all domains of axSpA. METHODS: A literature review and consensus process involved a steering committee and an expert panel of 37 rheumatologists and health professionals. The first steering committee took place in March 2022 and identified the main domains for inclusion in the standardized report. A hierarchical literature review was conducted to identify items within these domains and tools for assessment. The items and tools for assessment were discussed and consensus was reached through a vote session during an expert meeting that took place in March 2023. RESULTS: The steering committee identified four main domains to include in the standardized reporting framework: disease assessment, comorbidities, lifestyle, and quality of life. Items and tools for assessment were adopted after the expert meeting. Additionally, recommendations regarding digital tools (websites, apps, social media) were provided. CONCLUSION: This initiative led to a consensus, based on evidence and expertise, on a reporting framework for use during periodic systematic global evaluations of axSpa in daily practice.

Impact of the time of initiation and line of biologic therapy on the retention rate of secukinumab in axial spondyloarthritis (axSpA): data from the French multicentre retrospective FORSYA study.

OBJECTIVE: To compare the 1-year retention rate of secukinumab in axial spondyloarthritis (axSpA) and its predisposing factors with regard to its time of initiation (eg, right after or remotely from its launch). METHODS: Study design: Retrospective multicentre French study of patients with axSpA. Study periods: Two cohorts were evaluated regarding the time of initiation of secukinumab: cohort 1 (C1)-between 16 August 2016 and 31 August 2018-and cohort 2 (C2)-between 1 September 2018 and 13 November 2020. STATISTICAL ANALYSIS: The 1-year retention rate of secukinumab was estimated using the Kaplan-Meier method, and the log-rank test was used to compare the retention curves of the two cohorts. Preselected factors (eg, disease characterristics, line and time of secukinumab initiation) of secukinumab retention at 1 year were analysed by univariate and multivariate Cox model regression. RESULTS: In total, 906 patients in C1 and 758 in C2 from 50 centres were included in the analysis. The 1-year retention rate was better in C2 (64% (61%-68%)) vs C1 (59% (55%-62%)) (HR=1.19 (1.02-1.39); p=0.0297). In the multivariate analysis, the line of biologic therapy was the single predictive factor of the 1-year retention rate of secukinumab picked up in both cohorts, with a better retention rate when prescribed as first-line biologic therapy. CONCLUSION: The better secukinumab retention rate remotely from its launch is explained by its use at an earlier stage of the disease, suggesting a change in the behaviour of prescribing physicians. Our results emphasise the relevance of iterative evaluations of routine care treatments.

Two-year treatment persistence with subcutaneous abatacept in rheumatoid arthritis: results from the French cohort of the ASCORE study.

OBJECTIVES: While multiple studies have investigated treatment persistence rates with intravenous abatacept, limited information is available about real-world treatment continuation with the subcutaneous form. The international ASCORE study described the characteristics and treatment persistence of real-world patients with rheumatoid arthritis (RA) receiving subcutaneous abatacept. This article presents the findings of the French cohort. METHODS: This was an observational study in French RA patients who initiated subcutaneous abatacept between August 2014 and January 2017. The primary endpoint was treatment maintenance at 2 years, analysed according to the number of previous biologic therapies. RESULTS: Of 546 evaluable patients, 281 (51.5%) were biologic-naive, 265 (48.5%) had experienced failure with 1 (n=134; 24.5%) or ≥2 (n=131; 24.0%) biologic therapies. At enrolment, patients who had experienced failure with ≥1 biologic therapy had more erosions and a longer duration of RA compared with biologic-naive patients, but had comparable mean disease activity scores. Overall, 43.0% of patients (95% confidence interval 38.6-47.2) were still taking subcutaneous abatacept at 2 years, which was comparable with that in other countries participating in ASCORE. The abatacept persistence rate was higher in biologic-naive patients (48.8%) than in those with 1 (40.9%) or ≥2 (32.8%) biologic therapy failures. The main reason for discontinuing abatacept was lack of efficacy (46.6%). CONCLUSIONS: In current practice in France, the rate of subcutaneous abatacept persistence at 2 years was comparable with that of the intravenous form. Treatment persistence was higher when abatacept was used as first-line versus later-line biologic therapy.

Enthesitis in patients with psoriatic arthritis treated with secukinumab or adalimumab: a post hoc analysis of the EXCEED study.

OBJECTIVES: To evaluate enthesitis treatment response, including time to resolution and data from multiple enthesitis instruments, in patients with PsA treated with secukinumab or adalimumab for 52 weeks. METHODS: In this post hoc analysis of the EXCEED study, patients receiving secukinumab 300 mg or adalimumab 40 mg per the label were grouped by presence or absence of baseline enthesitis based on the Leeds Enthesitis Index (LEI) and the Spondyloarthritis Research Consortium of Canada Enthesitis Index (SPARCC). Efficacy was assessed according to several enthesitis-related instruments using non-responder imputation for the achievement of enthesitis resolution (LEI/SPARCC = 0), Kaplan-Meier analysis for time to resolution, and as-observed data for other outcomes. RESULTS: Enthesitis was present at baseline in 498 of 851 patients (58.5%) as assessed by LEI and in 632 of 853 patients (74.1%) as assessed by SPARCC. Patients with baseline enthesitis generally presented with greater disease activity. Similar proportions of patients receiving secukinumab or adalimumab achieved resolution of LEI and SPARCC at weeks 24 (secukinumab: LEI/SPARCC, 49.6%/45.8%; adalimumab: LEI/SPARCC, 43.6%/43.5%) and 52 (secukinumab: LEI/SPARCC, 60.7%/53.2%; adalimumab: LEI/SPARCC, 55.3%/51.4%), with comparable mean time to enthesitis resolution. Improvements were similar for both drugs at individual enthesitis sites. Resolution of enthesitis with secukinumab or adalimumab was associated with improvements in quality of life at week 52. CONCLUSION: Secukinumab and adalimumab showed similar efficacy, including time to resolution, with respect to resolution of enthesitis. Inhibition of IL-17 with secukinumab reduced clinical enthesitis similarly to TNF-α inhibition. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02745080.

Towards the Lowest Efficacious Dose: Results From a Multicenter Noninferiority Randomized Open-Label Controlled Trial Assessing Tocilizumab or Abatacept Injection Spacing in Rheumatoid Arthritis in Remission.

OBJECTIVE: We assess the clinical and structural impact at two years of progressively spacing tocilizumab (TCZ) or abatacept (ABA) injections versus maintenance at full dose in patients with rheumatoid arthritis in sustained remission. METHODS: This multicenter open-label noninferiority (NI) randomized clinical trial included patients with established rheumatoid arthritis in sustained remission receiving ABA or TCZ at a stable dose. Patients were randomized to treatment maintenance (M) at full dose (M-arm) or progressive injection spacing (S) driven by the Disease Activity Score in 28 joints every 3 months up to biologics discontinuation (S-arm). The primary end point was the evolution of disease activity according to the Disease Activity Score in 44 joints during the 2-year follow-up analyzed per protocol with a linear mixed-effects model, evaluated by an NI test based on the one-sided 95% confidence interval (95% CI) of the slope difference (NI margin 0.25). Other end points were flare incidence and structural damage progression. RESULTS: Overall, 202 of the 233 patients included were considered for per protocol analysis (90 in S-arm and 112 in M-arm). At the end of follow-up, 16.2% of the patients in the S-arm could discontinue their biologic disease-modifying antirheumatic drug, 46.9% tapered the dose and 36.9% returned to a full dose. NI was not demonstrated for the primary outcome, with a slope difference of 0.10 (95% CI 0.10-0.31) between the two arms. NI was not demonstrated for flare incidence (difference 42.6%, 95% CI 30.0-55.1) or rate of structural damage progression at two years (difference 13.9%, 95% CI -6.7 to 34.4). CONCLUSION: The Towards the Lowest Efficacious Dose trial failed to demonstrate NI for the proposed ABA or TCZ tapering strategy.

Efficacy of Janus kinase inhibitors in rheumatoid arthritis.

BACKGROUND: Janus kinase inhibitors (JAKis) is a new therapeutic class in autoimmune and inflammatory diseases. Four molecules are approved in rheumatoid arthritis (RA) in Europe. Recently, questions have raised about adverse events. In this context, a synthesis of the efficacy data of JAKis in RA is of use. METHOD: We performed a literature review based on published articles about efficacy of JAKis in RA, including clinical trials, registries, retrospective and prospective cohorts as well as database analysis. RESULTS: Based on the phase III clinical trials, JAKis are effective in comparison to placebo, methotrexate and tumour necrosis factor inhibitors. Based on registries, cohorts and post hoc analysis of phase III clinical trials, several parameters might modulate the efficacy of JAKis: the serological status, a short duration of the disease or the presence of poor prognostic factors. Preliminary data suggest that early ultrasonographic evaluation might help to predict the medium-term progression. CONCLUSION: Some clinical, biological and imaging parameters seem to influence the response to JAKis and should be evaluated in larger studies. In addition to factors that might influence the efficacy of JAKis, the safety profile and risk factors should be considered before initiating JAKis in a patient.

Factors associated with the retention of secukinumab in patients with axial spondyloarthritis in real-world practice: results from a retrospective study (FORSYA).

BACKGROUND: Secukinumab efficacy and retention data are emerging in patients with axial spondyloarthritis (axSpA) in real-world settings. However, limited data are available on the predictive factors that affect the retention rate. The key objective was to determine whether objective signs of inflammation (OSI) were predictive of secukinumab retention at 1 year. METHODS: FORSYA is a French, multicentric, non-interventional, retrospective study in adult axSpA patients who received secukinumab treatment between its launch (11 August 2016) and 31 August 2018. The time to secukinumab discontinuation and retention were analysed using a Kaplan-Meier (KM) analysis. OSI was predefined by at least one of the criteria: C reactive protein ≥5 mg/L or erythrocyte sedimentation rate ≥28 mm/hour at secukinumab initiation or MRI inflammation at the sacroiliac or spine level. RESULTS: In total, 906 patients from 48 centres were included in the analysis, 42.2% of whom were men, with a mean age of 46.2±11.7 years and a mean disease duration of 9.3±9.1 years. The 1-year KM retention rate (95% CI) for secukinumab was 59% (55%-62%), whereas for patients with and without OSI, it was 58% (54%-62%) and 63% (53%-73%), respectively. In multivariate analysis, lack of prior exposure to tumour necrosis factor inhibitor (TNFi), absence of OSI and inflammatory bowel disease (IBD) were associated with a better retention of secukinumab at 1 year. CONCLUSION: Following its approval in France, ~59% of axSpA patients retained secukinumab in daily practice, at 1 year. Prior exposure to TNFi, OSI and IBD were identified as risk factors for secukinumab discontinuation.

Clinical significance of a self-reported familial occurrence of rheumatoid arthritis among patients with recent-onset arthritis: data from the ESPOIR cohort.

OBJECTIVES: To assess, in patients with recent-onset arthritis, whether a self-reported familial occurrence of rheumatoid arthritis (RA) is associated with a clinical presentation of the disease, final diagnosis, long-term outcome and treatment decisions. METHODS: The study was conducted from data of patients included between 2002 and 2005 in the early arthritis ESPOIR cohort. Patients were recruited on the basis of having at least two swollen joints for >6 weeks and <6 months, no other diagnosis than RA and no previous exposure to glucocorticoids or disease-modifying antirheumatic drugs (DMARDs). Patients were stratified into two groups according to the presence of a self-reported familial occurrence of RA at baseline. Data concerning final diagnosis (2-year visit), long-term outcome (5-year visit) and therapeutic decisions were compared between the 2 groups of patients, using logistic and Cox regression models. RESULTS: At baseline, 115 patients (14.1%) reported a familial occurrence of RA and showed, as compared with the remaining participants, higher prevalence of extra articular manifestations (EAMs) (51.8% vs. 39.6%, p=0.01) and severe EAMs (7.9% vs. 3.1%, p 0.01). Both unadjusted (hazard ratio, 1.57; 95% CI, 1.1-2.21; p = 0.01) and adjusted analysis (hazard ratio, 1.51; 95% CI, 1.06-2.15; p=0.02) identified a higher probability for the initiation of a targeted DMARD over time among patients with a self-reported familial occurrence of RA. CONCLUSIONS: In the specific context of early arthritis, a self-reported familial occurrence of RA is associated with the future decision to initiate a targeted DMARD.

Impact of disease activity outcome measures reporting in the medical records of patients with axial spondyloarthritis on the retention rates of biological treatment: the example of secukinumab use in daily practice in France.

OBJECTIVES: To estimate the frequency of reporting composite indices evaluating axial spondyloarthritis (axSpA) disease activity in daily practice and to assess its impact on the secukinumab (SEC) retention rate. METHODS: Study design: Retrospective, multicentre. DATA COLLECTED: (1) Recommended composite indices: Bath Ankylosing Spondyltitis Disease Activity Index (BASDAI) +C reactive protein or Ankylosing Spondylitis Disease Activity Score (ASDAS) at the time of initiation of SEC and at least once during the first year of follow-up; (2) Drug retention rate: percentage of patients still on SEC over time according to whether at least one recommended composite index had been optimally reported. RESULTS: A recommended composite index has been collected in 22% of the 906 enrolled axSpA patients. The percentage of patients still on treatment after 1, 2 and 3 years of follow-up was greater in those for whom at least one composite index had been optimally reported (respectively, 64% (57-71) vs 57% (54-61), 55% (48-62) vs 41% (38-45) and 52% (44-59) vs 38% (34-42), log rank test, p=0.016) with a lower risk of SEC discontinuation for these patients (HR: 0.70 (95% CI 0.5 to 0.88), Cox model, p=0.003). CONCLUSION: This study suggests that reporting of recommended composites indices for monitoring axSpA might be associated with higher retention rates of biological therapies.

Factors associated with drug-free remission at 5-year in early onset axial spondyloarthritis patients: Data from the DESIR cohort.

OBJECTIVES: To assess the frequency of patients in drug-free remission at 5 years in a cohort of early axial SpA, and the factors associated with this remission. METHODS: Patients: patients included in the DESIR (DEvenir des Spondyloarthropathies Indifférenciées Récentes) cohort undergoing the 5-year visit were selected for this analysis. Definition of 5-year drug-free remission: (1) all patients in ASAS partial remission and/or ASDAS<1.3 at 5 year visit and (2) taking no disease modifying anti-rheumatic drugs at the 5-year visit and (3) with an ASAS-NSAID score≤25 at the 5-year visit. DATA ANALYSIS: the proportion of patients in drug-free remission was described. The association between demographic, clinical, biological and imaging characteristics and drug-free remission at 5 years was assessed by logistic regression. RESULTS: Of the 412 patients included in this analysis, 73 (18%) were in drug-free remission at the 5-year visit. The baseline clinical factors associated with the chances to be in drug-free remission at the 5-year visit were symptom duration (OR=0.66 [95%CI%: 0.44-0.97]), lower HAQ-AS score (OR=0.32 [0.12-0.78]), lower ASDAS score (OR=0.55 [95%CI: 0.34-0.86]), ASAS-NSAID score (OR=0.91 [95%CI: 0.82-0.99]). Furthermore, anti-TNF use (OR=0.20 [95%CI: 0.08-0.42]) during the follow-up decreased the chances of being in 5-year drug-free remission. CONCLUSION: The probability of being in drug free remission at 5 year when beginning an axial SpA is low and is associated with lower baseline disease activity and functional scores, while starting an anti-TNF is associated with poor chances of later being in drug-free remission. NCT01648907.

2022 French Society for Rheumatology (SFR) recommendations on the everyday management of patients with spondyloarthritis, including psoriatic arthritis.

OBJECTIVE: Update the French Society for Rheumatology (SFR) recommendations on the everyday management of patients with spondyloarthritis, including psoriatic arthritis. METHODS: Following standardized procedures, a systematic literature review was done by four supervised rheumatology residents based on questions defined by a task force of 16 attending rheumatologists. The findings were reviewed during three working meetings that culminated in each recommendation receiving a grade and the level of agreement among experts being determined. RESULTS: Five general principles and 15 recommendations were developed. They take into account pharmacological and non-pharmacological measures along with treatment methods based on the dominant phenotype present (axial, articular, enthesitis/dactylitis) and the extra-articular manifestations (psoriasis, inflammatory bowel disease, uveitis). NSAIDs are the first-line pharmacological treatment in the various presentations. Conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) are not indicated in the axial and isolated entheseal forms. If the response to conventional treatment is not adequate, targeted therapies (biologics, synthetics) should be considered; the indications depend on the clinical phenotype and presence of extra-articular manifestations. CONCLUSION: This update incorporates recent data (published since the prior update in 2018) and the predominant clinical phenotype concept. It aims to help physicians with the everyday management of patients affected by spondyloarthritis, including psoriatic arthritis.

Factors associated with remission at 5-year follow-up in recent-onset axial spondyloarthritis: results from the DESIR cohort.

OBJECTIVE: The factors contributing to long-term remission in axial SpA (axSpA) are unclear. We aimed to characterize individuals with axSpA at the 5-year follow-up to identify baseline factors associated with remission. METHODS: We included all patients from the DESIR cohort (with recent-onset axSpA) with an available Ankylosing Spondylitis Disease Activity Score-CRP (ASDAS-CRP) at 5-year follow-up. Patients in remission (ASDAS-CRP < 1.3) were compared with those with active disease by demographic, clinical, biological and imaging characteristics. A logistic model stratified on TNF inhibitor (TNFi) exposure was used. RESULTS: Overall, 111/449 patients (25%) were in remission after 5 years. Among those never exposed to TNFi, 31% (77/247) were in remission compared with 17% (34/202) of those exposed to TNFi. Patients in remission after 5 years were more likely to be male, HLA-B27+, have a lower BMI, and a higher education level. Baseline factors associated with 5-year remission in patients never exposed to TNFi included lower BASDAI [adjusted odds ratio (ORa) 0.9, 95% CI: 0.8, 0.9) and history of peripheral arthritis (ORa 2.1, 95% CI: 1.2, 5.3). In those exposed to TNFi, remission was associated with higher education level (ORa 2.9, 95% CI: 1.6, 5.1), lower enthesitis index (ORa 0.8, 95% CI: 0.7, 0.9), lower BASDAI (ORa 0.9, 95% CI: 0.9, 0.9) and lower BMI (ORa 0.8, 95% CI: 0.7, 0.9). CONCLUSION: This study highlights the difficulty in achieving 5-year remission in those with recent-onset axSpA, especially for the more active cases, despite the use of TNFi. Socio-economic factors and BMI are implicated in the outcome at 5 years.

New-onset inflammatory bowel diseases among IL-17 inhibitor-treated patients: results from the case-control MISSIL study.

OBJECTIVES: To describe new-onset IBD (new IBD) in patients treated with IL-17 inhibitors (IL-17i), to assess their incidence and to identify their risk factors in real life. METHODS: A French national registry (MISSIL) aimed to report all cases of new IBD in patients treated with IL-17i from January 2016 to December 2019. Using the estimated number of patients treated by IL-17 in France during the study period, the annual incidence rates of new IBD was reported in IL-17i-treated patients. A case-control study was performed with two controls per new IBD case matched by gender, age and underlying inflammatory disease. RESULTS: Thirty-one cases of new IBD under IL-17i were collected: 27 patients treated for spondyloarthritis and four patients for psoriasis. All were observed with secukinumab (SEK). The median time to onset of new IBD symptoms was 4.0 (1.5-7.5) months. SEK was discontinued in all patients. The evolution was favourable with complete resolution (17/31), improvement (7/31) or stabilization (5/31). Two patients died: one due to a massive myocardial infarction and one due to post-colectomy complications. The incidence of new IBD decreased from 0.69/100 patient-years [PY] (7/1010) in 2016 to 0.08/100 PY (6/7951) in 2019. No previous treatment with etanercept (odds ratio [OR] = 0.33, 95% CI: 0.14-0.80, P = 0.014) and low number of previous biologic therapies (OR = 0.67, 95% CI: 0.47, 0.94, P = 0.021) were significantly associated with new IBD. CONCLUSION: The incidence of new IBD was low and decreased from 2016 to 2019. The outcome was favourable in 24 out of 31 patients, but two patients died.
