Comparative efficacy and safety of bimekizumab in axial spondyloarthritis: a systematic literature review and network meta-analysis. Rheumatology (Oxford) 2024; 63:1195-1205. [PMID: 37947318 PMCID: PMC11065447 DOI: 10.1093/rheumatology/kead598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 09/19/2023] [Accepted: 10/17/2023] [Indexed: 11/12/2023] Open
Abstract
OBJECTIVES To compare the efficacy and safety of bimekizumab 160 mg every 4 weeks, a selective inhibitor of IL-17F and IL-17A, with those of biologic/targeted synthetic DMARDs (b/tsDMARDs) in non-radiographic axial SpA (nr-axSpA) and AS. METHODS A systematic literature review identified randomized controlled trials until January 2023 for inclusion in Bayesian network meta-analyses (NMAs), including three b/tsDMARDs exposure networks: predominantly-naïve, naïve, and experienced. Outcomes were Assessment of SpondyloArthritis international Society (ASAS)20, ASAS40 and ASAS partial remission (PR) response rates at 12-16 weeks. A safety NMA investigated discontinuations due to any reason and serious adverse events at 12-16 weeks. RESULTS The NMA included 36 trials. The predominantly-naïve network provided the most comprehensive results. In the predominantly-naïve nr-axSpA analysis, bimekizumab had significantly higher ASAS20 response rates vs secukinumab 150 mg [with loading dose (LD)/without LD], and comparable response rates vs other active comparators. In the predominantly-naïve AS analysis, bimekizumab had significantly higher ASAS40 response rates vs secukinumab 150 mg (without LD), significantly higher ASAS-PR response rates vs secukinumab 150 mg (with LD) and comparable response rates vs other active comparators. Bimekizumab demonstrated similar safety to that of other b/tsDMARDs. CONCLUSION Across ASAS outcomes, bimekizumab was comparable with most b/tsDMARDs, including ixekizumab, TNF inhibitors and upadacitinib, and achieved higher response rates vs secukinumab for some ASAS outcomes in predominantly b/tsDMARD-naïve nr-axSpA and AS patients at 12-16 weeks. In a pooled axSpA network, bimekizumab demonstrated comparable safety vs other b/tsDMARDs.

Work productivity in patients with axial spondyloarthritis initiating biological or targeted synthetic disease-modifying antirheumatic drugs: a systematic literature review and meta-analysis. RMD Open 2023; 9:e003468. [PMID: 38035757 PMCID: PMC10689353 DOI: 10.1136/rmdopen-2023-003468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Accepted: 09/04/2023] [Indexed: 12/02/2023] Open
Abstract
BACKGROUND Axial spondyloarthritis (axSpA) can limit work participation. Our objective was to characterise productivity in patients with axSpA, including changes after 12-16 weeks of treatment with biological and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). METHODS A systematic literature review identified studies published from 1 January 2010 to 21 October 2021 reporting work productivity using the Work Productivity and Activity Impairment (WPAI) questionnaire in patients with axSpA initiating b/tsDMARDs. Baseline and Week 12-16 overall work productivity, absenteeism, presenteeism and activity impairment scores were used in a random-effects meta-analysis to calculate absolute mean change from baseline for each WPAI-domain. RESULTS Eleven studies in patients with axSpA who received either placebo (n=727) or treatment with adalimumab, bimekizumab, etanercept, ixekizumab, secukinumab or tofacitinib (n=994) were included. In working patients initiating a b/tsDMARD, mean baseline overall work productivity impairment, absenteeism and presenteeism scores were 52.1% (N=7 studies), 11.0% and 48.8% (N=6 studies), respectively. At Week 12-16, the pooled mean change from baseline in overall work impairment for b/tsDMARDs or placebo was -21.6% and -12.3%. When results were extrapolated to 1 year, the potential annual reductions in cost of paid and unpaid productivity loss per patient ranged from €11 962.88 to €14 293.54. CONCLUSIONS Over 50% of employed patients with active axSpA experienced work impairment, primarily due to presenteeism. Overall work productivity improved at Weeks 12-16 to a greater extent for patients who received b/tsDMARDs than placebo. Work productivity loss was associated with a substantial cost burden, which was reduced with improvements in impairment.

Abstract
INTRODUCTION Psoriasis (PSO), psoriatic arthritis (PsA), axial spondyloarthritis (axSpA), and hidradenitis suppurativa (HS) are chronic inflammatory diseases (CIDs) often diagnosed and treated individually. However, genetic overlaps exist among CIDs, and patients with one are at risk of developing others within the same spectrum. This analysis characterized treatment patterns along with clinical and economic burdens of newly diagnosed CIDs among patients with an additional past diagnosis of PSO, PsA, axSpA, or HS. METHODS This study used MarketScan® databases to examine demographics, treatment patterns, and healthcare resource utilization for patients with ≥ 1 claim for PSO or HS or ≥ 2 claims for PsA or axSpA, and continuous enrollment in the year before (baseline period) and following (follow-up period) the date of first diagnosis (incident diagnosis). Comorbidities and new CID diagnoses with a past diagnosis of PSO, PsA, axSpA, or HS, were examined. RESULTS The analysis included 298,794 patients (maximum of 1202 patients with ≥ 1 incident diagnoses): 134,233 had incident PSO; 9914 had incident PsA; 115,194 had incident axSpA; and 40,655 had incident HS. Prevalence of ≥ 1 CID diagnosis among patients with past diagnosis of PSO, PsA, axSpA, or HS was 4959/134,233 (3.7%), 5256/9914 (53.0%), 3205/115,194 (2.8%), and 1180/40,655 (2.9%), respectively. In patients with incident axSpA and past PsA diagnosis, incident axSpA and past HS diagnosis, and incident HS and past PSO diagnosis, steroid and opioid use were high across baseline and follow-up periods and use of biologic disease-modifying antirheumatic drugs increased from baseline to follow-up. Disease-related costs increased absolutely and increased or remained high as a proportion of all-cause costs. CONCLUSION Patients with newly diagnosed CIDs and additional past diagnosis of PSO, PsA, axSpA, or HS experienced high treatment utilization and healthcare costs. These findings highlight the need for payers, health technology assessment agencies, clinicians, and other stakeholders to explore the co-management of CIDs, rather than treating them separately.

The Impact of Spondyloarthritis on Health-Related Quality of Life and Healthcare Resource Utilization in Saudi Arabia: A Narrative Review and Directions for Future Research. Open Access Rheumatol 2023; 15:161-171. [PMID: 37705696 PMCID: PMC10497044 DOI: 10.2147/oarrr.s414530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 07/04/2023] [Indexed: 09/15/2023] Open
Abstract
Spondylarthritis (SpA) is an umbrella term that encompasses a wide range of rheumatological disorders. Several studies demonstrated that SpA is associated with increased healthcare resource utilization (HCRU) and a lower health-related quality of life (HRQoL). This review aimed to summarize the current literature regarding the multidimensional impact of SpA on HRQoL and HCRU in Saudi Arabia and explore the correlation of the extent of severity of SpA with HRQoL and HCRU. Although the prevalence of SpA varies across different populations and is correlated with HLA-B27 prevalence, the magnitude of SpA in the Saudi population has not been extensively evaluated. Few studies have investigated the impact of SpA on HRQoL and HCRU in Saudi Arabia and the Middle East. There is a need to study the cost-effectiveness of various SpA treatment strategies, including biologic disease-modifying anti-rheumatic drugs (bDMARDs), to prioritize healthcare spending in the Saudi healthcare system. Data on SpA in Saudi Arabia and the Middle East region are mainly based on expert views, with few population-based studies compared to other regions. Therefore, there is an imperative need to develop high-quality, national-level epidemiological studies that assess the following: (1) more accurate estimates of the current prevalence of SpA in Saudi Arabia, including the prevalence of axial SpA and psoriatic arthritis; (2) the phenotypes/clinical characteristics of SpA, including disease severity and extra-articular involvement; (3) the impact of SpA on the HRQoL of the patients and the factors that can predict the extent of impaired HRQoL in such population, which can represent the first step in developing psychological interventions that should be personalized to this patient population; (4) the impact of implementing formal assessment of disease activity on the management of the patients and, subsequently, their HRQoL; and (5) the HCRU and costs for patients with SpA, and how treatment patterns can affect this cost.

Abstract
INTRODUCTION To evaluate the effect of upadacitinib vs. placebo on health-related quality of life (HRQoL) and work productivity in patients with active non-radiographic axial spondyloarthritis (nr-axSpA) enrolled in the SELECT-AXIS 2 phase 3 randomized controlled trial. METHODS Adult patients with active nr-axSpA and an inadequate response to non-steroidal anti-inflammatory drugs were randomized 1:1 to receive upadacitinib 15 mg once daily or placebo. Mean changes from baseline in measures of HRQoL (Ankylosing Spondylitis QoL [ASQoL], Assessment of SpondyloArthritis international Society Health Index [ASAS HI], Short-Form 36 Physical Component Summary [SF-36 PCS] score) and Work Productivity and Activity Impairment (WPAI) were assessed through 14 weeks based on mixed-effects repeated measures or analysis of covariance models. The proportions of patients with improvements ≥ minimum clinically important differences (MCID) were assessed in HRQoL measures at week 14 using non-responder imputation with multiple imputation. RESULTS At week 14, upadacitinib- vs. placebo-treated patients reported greater improvements from baseline in ASQoL and ASAS HI (ranked, P < 0.001) and in SF-36 PCS and WPAI overall work impairment (nominal P < 0.05). Improvements were observed as early as week 2 in ASAS HI. Greater proportions of upadacitinib vs. placebo-treated patients reported improvements ≥ MCID in ASQoL (62.6 vs. 40.9%), ASAS HI (44.8 vs. 28.8%), and SF-36 PCS (69.3 vs. 52.0%), with numbers needed to treat < 10 for all (nominal P ≤ 0.01). Improvements ≥ MCID were consistently observed irrespectively of prior exposure to tumor necrosis factor inhibitors. CONCLUSIONS Upadacitinib provides clinically meaningful improvements in HRQoL and work productivity in patients with active nr-axSpA. CLINICAL REGISTRATION NUMBER NCT04169373, SELECT-AXIS 2.

Abstract
BACKGROUND Radiographic progression and course of inflammation over 2 years in patients with non-radiographic axial spondyloarthritis (nr-axSpA) from the phase 3, randomized, PREVENT study are reported here. METHODS In the PREVENT study, adult patients fulfilling the Assessment of SpondyloArthritis International Society classification criteria for nr-axSpA with elevated CRP and/or MRI inflammation received secukinumab 150 mg or placebo. All patients received open-label secukinumab from week 52 onward. Sacroiliac (SI) joint and spinal radiographs were scored using the modified New York (mNY) grading (total sacroiliitis score; range, 0-8) and modified Stoke Ankylosing Spondylitis Spine Score (mSASSS; range, 0-72), respectively. SI joint bone marrow edema (BME) was assessed using the Berlin Active Inflammatory Lesions Scoring (0-24) and spinal MRI using the Berlin modification of the AS spine MRI (ASspiMRI) scoring (0-69). RESULTS Overall, 78.9% (438/555) of patients completed week 104 of the study. Over 2 years, minimal changes were observed in total radiographic SI joint scores (mean [SD] change, - 0.04 [0.49] and 0.04 [0.36]) and mSASSS scores (0.04 [0.47] and 0.07 [0.36]) in the secukinumab and placebo-secukinumab groups. Most of the patients showed no structural progression (increase ≤ smallest detectable change) in SI joint score (87.7% and 85.6%) and mSASSS score (97.5% and 97.1%) in the secukinumab and placebo-secukinumab groups. Only 3.3% (n = 7) and 2.9% (n = 3) of patients in the secukinumab and placebo-secukinumab groups, respectively, who were mNY-negative at baseline were scored as mNY-positive at week 104. Overall, 1.7% and 3.4% of patients with no syndesmophytes at baseline in the secukinumab and placebo-secukinumab group, respectively, developed ≥ 1 new syndesmophyte over 2 years. Reduction in SI joint BME observed at week 16 with secukinumab (mean [SD], - 1.23 [2.81] vs - 0.37 [1.90] with placebo) was sustained through week 104 (- 1.73 [3.49]). Spinal inflammation on MRI was low at baseline (mean score, 0.82 and 1.07 in the secukinumab and placebo groups, respectively) and remained low (mean score, 0.56 at week 104). CONCLUSION Structural damage was low at baseline and most patients showed no radiographic progression in SI joints and spine over 2 years in the secukinumab and placebo-secukinumab groups. Secukinumab reduced SI joint inflammation, which was sustained over 2 years. TRIAL REGISTRATION ClinicalTrials.gov, NCT02696031.

Abstract
INTRODUCTION Biologic disease-modifying anti-rheumatic drugs (bDMARDs), including certolizumab pegol (CZP), are effective treatment options for the management of non-radiographic spondyloarthritis (nr-axSpA). In the absence of head-to-head comparisons in nr-axSpA, we conducted a systematic literature review (SLR) and indirect treatment comparison (ITC) to better understand the comparative efficacy of CZP vs. other bDMARDs. METHODS Literature searches were conducted in October 2020 in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials to identify randomized controlled trials in patients with nr-axSpA who had failed at least one non-steroidal anti-inflammatory drug and were treated with bDMARDs. Outcomes of interest included the Assessment of Spondyloarthritis international Society (ASAS), Ankylosing Spondylitis Disease Activity Score (ASDAS), Bath Ankylosing Spondylitis Functional Index (BASFI) and Disease Activity Index (BASDAI), and spinal pain score. Comparative efficacy was examined using a series of Bucher ITCs in subgroups matched by prior exposure to bDMARDs, disease duration, baseline C-reactive protein (CRP) levels/magnetic resonance imaging (MRI) status, and timepoints, to ensure comparability between studies. RESULTS At 12-16 weeks, treatment with CZP was significantly more likely to achieve ASAS20/40 response and ASDAS-inactive disease status vs. etanercept (ETN), ixekizumab (IXE), and secukinumab (SEC). CZP showed statistically significant improvement in BASDAI, BASFI, and total spine pain score over adalimumab (ADA), ETN, and IXE, and in BASFI over SEC. Among patients with objective signs of inflammation (OSI; elevated CRP levels and/or inflammation on MRI at baseline), CZP had a statistically significant advantage over ETN and SEC (with or without loading dose) in achieving ASAS40, whereas the comparisons with other bDMARDs did not show any statistically significant differences. CONCLUSION In the overall matched population, CZP performed significantly better than most comparators in improving the clinical outcomes. Among patients with OSI, CZP was found to be superior to SEC (in the MRI-/CRP + and MRI + /CRP- subgroups) and ETN (in the MRI + /CRP- subgroup) and it was comparable to golimumab and IXE across the different OSI subgroups.

Abstract
Non-radiographic axial spondyloarthropathy (nr-axSpA) is a clinical diagnosis of symptoms matching inflammatory back pain criteria without radiological lesions at the sacroiliac joint. The frequency of an early nr-axSpA-like presentation in lymphoma patients has not been clarified. Here we report a woman in her 20s with a fever and musculoskeletal discomfort. Detailed investigations revealed that she was suffering from Burkitt lymphoma in which nr-axSpA-like symptoms were a musculoskeletal manifestation of the disease, irrelevant to the anti-neoplastic treatment.

Abstract
Purpose of Review Psoriatic arthritis and ankylosing spondylitis belong to a family of rheumatological diseases that lead to painful joint inflammation that impacts on patient function and quality of life. Recent studies have shown that the pro-inflammatory cytokine IL-17 is involved in the inflammatory joint changes in spondyloarthritides. We will review the pathophysiology of IL-17 and review the biological therapies targeting IL-17. Recent Findings IL-17 is produced and released from T cells and is dependent on multiple upstream cytokines, which include IL-23. There are six members of the IL-17 family that are secreted from multiple populations of T cells. The initial biologic medications have been developed against IL-17A, which is the best-studied member of this family. These medications appear to be effective in controlling joint inflammation, improving patient quality of life, and are generally well tolerated. More recently, medications have been developed that target both IL-17A and IL-17F. In addition, brodalumab, an antibody targeting the IL-17 receptor, has had a resurgence after initial concerns for an increased risk of suicide. Summary IL-17 is an inflammatory cytokine that is critical in the pathobiology of axial spondyloarthritides. Recent biological therapies targeting IL-17A are effective and well tolerated in patients with axial spondyloarthritis. Specific targeting of the Il-17A/F heterodimer is also effective and provides another viable option in the clinician’s armamentarium.

Abstract
OBJECTIVE To assess the effect of filgotinib, which preferentially inhibits Janus kinase 1 (JAK1), on MRI measures of structural change in the SI joint in patients with active AS in the TORTUGA trial. METHODS Adults with active AS and inadequate response/intolerance to two or more NSAIDs were randomized 1:1 to filgotinib 200 mg (n = 58) or placebo (n = 58) once daily for 12 weeks. In this post hoc analysis, T1-weighted MRI scans of the SI joint were evaluated by two independent readers using Spondyloarthritis Research Consortium of Canada (SPARCC) Sacroiliac Joint Structural Score (SSS) definitions for erosion, backfill, fat metaplasia and ankylosis. Correlations between SPARCC SSS and improvement in clinical outcomes were also assessed. RESULTS MRI scans from 87 patients (48 filgotinib, 39 placebo) were evaluated. At baseline there were no notable differences between filgotinib and placebo for any MRI structural lesion types. From baseline to week 12, filgotinib was associated with a significant reduction in SI joint erosion score (P = 0.02) and an increase in backfill score (P = 0.005) vs placebo, with no significant between-group differences for ankylosis (P = 0.46) or fat metaplasia (P = 0.17). At week 12, the change in SPARCC MRI SI joint inflammation scores correlated positively with erosion scores but negatively with backfill scores. CONCLUSION The significant changes in MRI structural lesions induced by filgotinib in the SI joint by week 12 demonstrate that tissue repair can be observed very soon after starting treatment with a JAK1 preferential inhibitor. This could have prognostic implications for development of ankylosis. TRIAL REGISTRATION ClinicalTrials.gov, http://clinicaltrials.gov, NCT03117270.

Abstract
:
Radiology plays key roles in diagnosis of arthritis. We herein suggest an algorithmic approach to diagnosing arthritis. First, the number of joint involvements is reviewed. Monoarticular arthritis includes septic arthritis, pigmented villonodular synovitis, and synovial chondromatosis. Second, polyarticular arthritis can be categorized by its characteristics: erosive, productive and mixed. Erosive disease includes rheumatoid arthritis, hemophilia, and amyloidosis while productive disease includes osteoarthritis, and hemochromatosis. Third, mixed diseases are subcategorized by symmetricity. Ankylosing spondylitis and inflammatory bowel disease related arthritis affect joints symmetrically while psoriatic arthritis, reactive arthritis, and crystalline arthropathy are asymmetric. Adjacent soft tissue density, periostitis, and bone density are ancillary findings that can be used as additional differential diagnostic clues. The final step in identifying the type of arthritis is to check whether the location is a site frequently affected by one particular disease over another. This systematic approach would be helpful for radiologist to diagnose arthritis.

Abstract
Nonradiographic axial spondyloarthritis (nr-axSpA) represents a distinct phenotype within the spectrum of axial spondyloarthritis (axSpA), which is characterized by a range of clinical manifestations. Despite a high disease burden that is comparable to ankylosing spondylitis (also known as radiographic axSpA), there is an unmet need to recognize and effectively manage patients with active nr-axSpA.A targeted literature search was conducted in OVID (MEDLINE and Embase databases) to identify articles on nr-axSpA, including its definition, demographics, epidemiology, burden, diagnosis, clinical presentation, and treatment guidelines.The lack of adequate epidemiological data and incomplete understanding of nr-axSpA among rheumatologists and nonrheumatologists contributes to delayed referrals and diagnosis. This delay results in a substantial burden on patients, physically and psychologically, and the healthcare system. Targeted therapies, such as biologics, including inhibitors of tumor necrosis factor or interleukin-17A, have been approved and utilized for the management of nr-axSpA, and other novel therapeutics with different mechanisms of action are in development. Raising awareness among US internists regarding the prevalence of nr-axSpA, disease burden, clinical presentation, diagnostic tools, and available treatments is important for improved disease management.Future clinical investigations focusing on the development of markers that aid early diagnosis and predict treatment response may also improve the management of nr-axSpA. This review provides an overview of nr-axSpA with the aim of raising awareness of the disease among US internists, with an overarching goal to contribute toward the improved recognition and timely referral of these patients to rheumatologists for diagnosis and management.

Abstract
Objective To reduce the diagnostic delay in axial spondyloarthritis (axSpA), guidelines recommend to refer patients with acute anterior uveitis (AAU) and chronic back pain (CBP) to a rheumatologist. This observational study evaluated the prevalence of previously unrecognized axSpA in AAU patients with CBP in daily practice, referred by ophthalmologists who had received instructions to increase awareness. Methods All AAU patients referred with CBP (≥3 months, started <45 years of age), from five Ophthalmology clinics underwent rheumatologic assessment, including pelvic X-rays. Patients with previously diagnosed rheumatic disease and established other cause of AAU were excluded. The primary endpoint was a clinical axSpA diagnosis by the rheumatologist. Results Eighty-one patients fulfilled the referral criteria (52% male, 56% HLA-B27 positive, median age 41 years, median CBP duration 10 years). In total, 58% (n=47) had recurring AAU, of whom 87% already had CBP during previous AAU attacks. After assessment, 23% (n=19) of patients were clinically diagnosed with definite-axSpA (10/19 radiographic), 40% (n=32) were suspicious of axSpA and 37% (n=30) did not have axSpA. AxSpA was diagnosed more often in men (33% of the men versus 13% of women). Conclusion A high prevalence of axSpA was found in AAU patients referred because of CBP. There was substantial diagnostic delay in the majority of patients with recurring AAU, as many already had back pain during previous AAU flares. In AAU, screening for CBP and prompt referral has a high diagnostic yield, and should consistently be promoted among ophthalmologists.

Abstract
Purpose To explore the diagnostic performance of the optimized threshold b values on IVIM to detect the activity in axial spondyloarthritis (axSpA) patients. Method 40 axSpA patients in the active group, 144 axSpA patients in the inactive group, and 20 healthy volunteers were used to evaluate the tissue diffusion coefficient (Dslow), perfusion fraction (f), and pseudodiffusion coefficient (Dfast) with b thresholds of 10, 20, and 30 s/mm2. The Kruskal-Wallis test and one way ANOVA test was used to compare the different activity among the three groups in axSpA patients, and receiver operating characteristic (ROC) curve analysis was applied to evaluate the performance for Dslow, f, and Dfast to detect the activity in axSpA patients, respectively. Results Dslow demonstrated a statistical difference between two groups (P < 0.05) with all threshold b values. With the threshold b value of 30 s/mm2, f could discriminate the active from control groups (P < 0.05). Dslow had similar performance between the active and the inactive groups with threshold b values of 10, 20, and 30 s/mm2 (AUC: 0.877, 0.882, and 0.881, respectively, all P < 0.017). Using the optimized threshold b value of 30 s/mm2, f showed the best performance to separate the active from the inactive and the control groups with AUC of 0.613 and 0.738 (both P < 0.017) among all threshold b values. Conclusion Dslow and f exhibited increased diagnostic performance using the optimized threshold b value of 30 s/mm2 compared with 10 and 20 s/mm2, whereas Dfast did not.

Abstract
Background The understanding of non-radiographic axial spondyloarthritis (nr-axSpA) has accelerated over the last decade, producing a number of practice-changing developments. Diagnosis is challenging. No diagnostic criteria exist, no single finding is diagnostic, and other causes of back pain may act as confounders. Aim To update and expand the 2014 consensus statement on the investigation and management of non‐radiographic axial spondyloarthritis (nr-axSpA). Methods We created search questions based on our previous statements and four new topics then searched the MEDLINE and Cochrane databases. We assessed relevant publications by full-text review and rated their level of evidence using the GRADE system. We compiled a GRADE evidence summary then produced and voted on consensus statements. Results We identified 5145 relevant publications, full-text reviewed 504, and included 176 in the evidence summary. We developed and voted on 22 consensus statements. All had high agreement. Diagnosis of nr-axSpA should be made by experienced clinicians, considering clinical features of spondyloarthritis, blood tests, and imaging. History and examination should also assess alternative causes of back pain and related conditions including non-specific back pain and fibromyalgia. Initial investigations should include CRP, HLA-B27, and AP pelvic radiography. Further imaging by T1 and STIR MRI of the sacroiliac joints is useful if radiography does not show definite changes. MRI provides moderate-to-high sensitivity and high specificity for nr-axSpA. Acute signs of sacroiliitis on MRI are not specific and have been observed in the absence of spondyloarthritis. Initial management should involve NSAIDs and a regular exercise program, while TNF and IL-17 inhibitors can be used for high disease activity unresponsive to these interventions. Goals of treatment include improving the frequent impairment of social and occupational function that occurs in nr-axSpA. Conclusions We provide 22 evidence-based consensus statements to provide practical guidance in the assessment and management of nr-axSpA.

Abstract
Background Patients with non-radiographic axial spondyloarthritis experience negative impacts on sleep, work productivity, and activity impairment. Ixekizumab, a monoclonal antibody selectively targeting interleukin-17A, has shown efficacy in treating the signs and symptoms of non-radiographic axial spondyloarthritis. This analysis evaluated the effect of ixekizumab treatment on sleep, work productivity, and activity impairment in patients with non-radiographic axial spondyloarthritis. Methods COAST-X (NCT02757352) was a 52-week, phase 3, multicenter, randomised placebo-controlled trial evaluating 80-mg ixekizumab every 2 weeks and every 4 weeks in patients with active non-radiographic axial spondyloarthritis. Sleep disturbance was measured with the Jenkins Sleep Evaluation Questionnaire (JSEQ) and analysed using mixed-effects models for repeated measures. Work productivity and activity impairment were measured using the Work Productivity and Activity Impairment Questionnaire for Spondyloarthritis and analysed using analysis of covariance. Absenteeism, presenteeism, and overall work impairment were assessed for patients reporting paid work; activity impairment was assessed regardless of work status. Results Overall, patients treated with both dosing regimens of ixekizumab reported numerically greater improvements in sleep than placebo through Week 52. At Weeks 16 and 52, patients treated with ixekizumab every 4 weeks had significantly greater improvements in presenteeism (p = 0.007 and p = 0.003, respectively) and overall work impairment (p = 0.014 and p = 0.005, respectively) and numeric improvements in absenteeism than placebo. Patients treated with ixekizumab every 2 weeks had numerically greater improvements in absenteeism, presenteeism, and overall work impairment than placebo. Both dosing regimens of ixekizumab were associated with significantly greater improvements in activity impairment than placebo (ixekizumab every 4 weeks: p = 0.003 at Week 16 and p = 0.004 at Week 52; ixekizumab every 2 weeks: p = 0.007 at Week 16 and p = 0.006 at Week 52). Conclusions Treatment with ixekizumab improved sleep, work productivity, and activity impairment in patients with nr-axSpA. Improvements in presenteeism and overall work impairment were sustained and consistent in the patients treated with ixekizumab every 4 weeks from Week 16 to Week 52. Improvements in activity impairment were sustained and consistent in both ixekizumab-treated groups from Week 16 to Week 52. Trial registration NCT02757352, May 2, 2016.

Abstract
Introduction The aim of this work is to perform a systematic review and meta-analysis of anti-tumor necrosis factor (anti-TNF) and anti-interleukin-17 (anti-IL-17) trials for spondyloarthritis, psoriatic arthritis, and psoriasis comparing rates of inflammatory bowel disease (IBD) events compared to placebo. Methods MEDLINE, EMBASE, and The Cochrane Library were searched for double-blind, randomized placebo-controlled anti-TNF and anti-IL-17 trials of included diseases. Inflammatory bowel disease events from the RCT period were pooled and meta-analyzed using statistical methods suitable for low-event-rate meta-analysis (Peto’s, Mantel–Haenszel, hypergeometric-normal model, and Shuster-Guo-Skyler). When observed data were insufficient, we performed an exploratory sensitivity analysis to compare methods. Results We identified 9551 original papers, and included 96 publications: 65 anti-TNF and 31 anti-IL-17 trials, containing 21 new and 12 flare IBD events in 28,209 participants. New IBD on anti-IL-17 occurred 0.23/100 patient-years (PY) in psoriasis, 0.61/100 PY in PsA and 1.63/100 PY in spondyloarthritis, rates similar to observational cohorts, and less commonly on anti-TNF (0/100 PY, 0/100 PY, 0.32/100 PY, respectively). No evidence of difference between groups was found, with wide CI from many pooled counts of zero, especially in placebo arms. Conclusions IBD events were rare, occurring at rates similar to biologic-naive groups. We could not find statistically significant differences in risk of new or recurrent IBD between treatment and control groups using selected meta-analytical methods for low event rate scenarios. Meta-analyses of this topic require more IBD events, ideally without pooling heterogeneous groups. Larger, thoroughly reported trials with systematic and detailed safety reporting are required to improve risk estimation and to make accurate inferences.

Abstract
Objective Biological agents have shown markedly different response rates by baseline C‐reactive protein (CRP). Here, we determine the response of patients with nonradiographic axial spondyloarthritis (nr‐axSpA) to etanercept stratified by their baseline CRP level. Methods The EMBARK trial was a phase 3, randomized, double‐blind, placebo‐controlled study of etanercept in nr‐axSpA. The primary endpoint was Assessment of Spondyloarthritis International Society (ASAS) 40 at Week 12, the conclusion of the double‐blind phase. It recruited patients who met the ASAS criteria for axial spondyloarthritis, and sacroiliac joint magnetic resonance scans were completed on all patients. In this post hoc analysis, we analyzed outcomes by baseline C‐reactive protein (CRP) level of less than 5 mg/L, 5 mg/L to 10 mg/L, and greater than 10 mg/L. The clinical trial outcome data were accessed via the Vivli platform. Results In the less than 5 mg/L CRP group treated with etanercept, the ASAS20 response, ASAS40 response, Ankylosing Spondylitis Disease Activity Score‐CRP (ASDAS‐CRP), and ASDAS‐ESR (erythrocyte sedimentation rate) outcomes were 49% (P = 0.84), 26% (P = 0.14), 42% (P = 0.002), and 44% (P = 0.006), respectively. In the 5 to 10 mg/L CRP group treated with etanercept, the ASAS20 response, ASAS40 response, ASDAS‐CRP, and ASDAS‐ESR outcomes were 56% (P = 0.99), 31% (P = 0.40), 56% (P = 0.16), and 50% (P = 0.11), respectively. In the greater than10 mg/L CRP group treated with etanercept, the ASAS20 response, ASAS40 response, ASDAS‐CRP, and ASDAS‐ESR outcomes were 74% (P = 0.02), 68% (P = 0.003), 82% (P = 0.005), and 50% (P = 0.001), respectively. Conclusion Although there are reduced ASAS20 and ASAS40 response rates in the groups with baseline CRP less than 10 mg/L, there remain clinically relevant responses when the composite outcome measures ASDAS‐CRP or ASDAS‐ESR were used, and this should be considered when deciding on thresholds for reimbursement.

Abstract
Although our understanding of axial spondyloarthropathy (axSpA) has increased recently, there has not been a concurrent improvement in patient diagnosis with delays contributing to patient morbidity. Imaging findings of axSpA can be subtle and may be dismissed often due to lack of understanding by reporters and importantly clinicians who do not suspect the disease. Recognition of the importance of imaging has led to the inclusion of MRI as part of the diagnostic criteria for axSpA. With this in mind, a number of advancements have been made in an attempt to increase our diagnostic accuracy on imaging. This article will give an overview of these techniques as well as a recap of the imaging features of axSpA.

PURPOSE OF REVIEW This review examines axial spondyloarthritis (axSpA) and the wider field of rheumatology through a value-based healthcare (VBHC) lens. VBHC is focused on ensuring patients receive high quality care to improve outcomes and reduce unnecessary costs. RECENT FINDINGS There are many opportunities to apply the principles of VBHC in axSpA. These include the appropriate utilization of diagnostic investigations, such as HLA-B27 and magnetic resonance imaging, assessing outcomes meaningful to patients, and optimizing care pathways. Multidisciplinary care may improve value, and reduced specialist review and medication tapering may be appropriate. Increasing the value of the care we provide to patients can occur across domains and directly and indirectly improves patient outcomes. Taking the time to integrate principles of VBHC into our practice will allow us to justifiably gain and maintain access to diagnostic and therapeutic advances for the benefit of all our patients.

Abstract
PURPOSE OF REVIEW Physical therapy is recommended for the management of axial spondyloarthritis (axSpA) with the focus of promoting physical activity and prescribing exercise within four domains, outlined recently by the European League against Rheumatism (EULAR): aerobic, resistance, flexibility and neuro-motor exercise. There is an increasing evidence base to support physical therapy interventions in axSpA. RECENT FINDINGS We present evidence supporting the use of exercise as treatment for patients with axSpA, recent updates among different exercise modalities, and make clear its critical place in the management of this condition. Recent large, multicentre data have shown that high-intensity exercise can improve disease activity and also positively impact cardiovascular risk factors in these patients. Although international treatment guidelines advocate the inclusion of physical activity and exercise for the optimal management of axSpA, specific guidance about the amount of exercise required to produce a beneficial effect is lacking. SUMMARY Exercise must be used in the management of axSpA, and whilst hydrotherapy and flexibility exercises are traditionally the main focus, other applications, such as strength training, may be underutilized domains. Further studies are needed to determine the dose-response relationship between exercise and axSpA patient subsets.

Abstract
There have been major advances in the management of axial spondyloarthritis (axSpA) with the introduction of effective biologic agents targeting TNF and IL-17A. Clinicians now have more choice but, despite treatment recommendations, are still faced with significant uncertainty when deciding on the optimal treatment strategy for an individual patient in clinical practice. Management of axSpA typically requires both non-pharmacological and pharmacological interventions. NSAIDs remain the first line drug therapies for axSpA with proven efficacy for symptomatic management but uncertainty remains regarding their optimal long-term use relating to radiographic progression and safety in axSpA. To-date there are no head-to-head trials of biologics in axSpA. Clinicians need to consider other factors, including extra-articular manifestations, comorbidities, safety and radiographic progression when deciding on which biologic to recommend for an individual patient. This article will explore the evidence relating to these factors and highlight areas of unmet need.

Abstract
In this scoping review, we sought to summarize the types of outcomes collected in pregnant patients with ankylosing spondylitis (AS), and to identify some methodological limitations related to pregnancy research in these patients. A comprehensive search was done to identify relevant articles in MEDLINE and Embase. We included 21 studies assessing pregnancy outcomes in AS. Most studies reported disease flare during pregnancy, and few reported improved disease activity or stable disease. Disease flare occurred in 25-80% of patients during pregnancy and in 30-100% during the postpartum. There was no increased risk of pre-eclampsia across all studies. Based on two case-control studies, there was an increased risk for prematurity and small for gestational age in AS pregnancies, pooled odds ratio (95% confidence interval) 1.99 (1.30-3.05) and 2.41 (1.22-4.77), respectively. The etiologies of cesarean section were not related to joint issues from AS but were related to other causes like pre-eclampsia and prematurity. Some key methodological issues were related to the study design, selection of study participants, disease classification, choice of control participants, and outcome measures. Based on the current literature review, some key areas for future research should evaluate the disease state at conception, effects of pharmacological treatment for AS during pregnancy, and long-term outcomes of children born to women with AS. The use of pregnancy registers and validated measurement tools in pregnancy will help to improve the state and quality of evidence in this field. Key Points • Disease flare during pregnancy in patients with ankylosing spondylitis (AS) occurred in 25-80% of the cases in the various studies, and in 30-100% of the cases during the postpartum period. • There was an increased risk for prematurity, and no increased risk of pre-eclampsia or small for gestational age. Etiologies of cesarean section were not related to the hip or sacroiliac joint affection of the disease but to other causes like pre-eclampsia and prematurity. • This study provides a comprehensive overview of issues related to research on pregnant women with ankylosing spondylitis (AS). We addressed methodological issues related to the study design, selection of study participants, disease classification, control choice, assessment of outcomes measures, and statistical analysis. • The use of pregnancy registers and validated disease activity measurement tools for pregnancy can enhance pregnancy research in women with AS.

Abstract
The axial spondyloarthritis (axSpA) disease concept has undergone substantial change from when the entity ankylosing spondylitis was defined by the modified New York criteria in 1984. Developments in imaging, therapy and genetics have all contributed to changing the concept of axSpA from one of erosions in the sacroiliac joints to a spectrum of disease with and without changes evident on plain radiographs. Changes to the previously held concept and construct of the disease have also necessitated new classification criteria. The use of MRI, primarily of the sacroiliac joints, has substantially altered the diagnosis and differential diagnosis of axSpA. Many in the axSpA community believe that the current classification criteria lack specificity, and the CLASSIC study is underway to examine this area. Although much about the evolving axSpA disease concept is universally agreed, there remains disagreement about operationalizing aspects of it, such as the requirement for the objective demonstration of axial inflammation for the classification of axSpA. New imaging technologies, biomarkers and genetics data will probably necessitate ongoing revision of axSpA classification criteria. Advances in our knowledge of the biology of axSpA will settle some differences in opinion as to how the disease concept is applied to the classification and diagnosis of patients.

Ixekizumab Improves Patient-Reported Outcomes in Non-Radiographic Axial Spondyloarthritis: Results from the Coast-X Trial. Rheumatol Ther 2020; 8:135-150.

Abstract
Introduction Ixekizumab, an interleukin-17A antibody, has shown efficacy in non-radiographic axial spondyloarthritis (nr-axSpA). The objectives of this analysis were (a) to measure improvement in ixekizumab-treated patients in Assessment of Spondyloarthritis International Society (ASAS) response domains and other patient-reported outcomes (PROs) and (b) to determine how ASAS responses were associated with changes in patient global disease activity (PtGA), spinal pain, function, stiffness, fatigue, and spinal pain at night. Methods COAST-X was a phase 3, 52-week multicenter, randomized, controlled trial investigating the efficacy and safety of 80-mg ixekizumab every 2 weeks (Q2W) and every 4 weeks (Q4W) in patients with active nr-axSpA. Changes from baseline in PROs were analyzed via mixed-effects models for repeated measures. Association analyses for ASAS responses used analysis of covariance with Scheffé’s method. Results Patients treated with ixekizumab Q2W and Q4W reported significantly greater improvements in PtGA, spinal pain, function, and stiffness at week 1, when these measures were first assessed, compared with placebo (p < 0.05). ASAS40 responders, in comparison to ASAS20 non-responders, had the highest correlations with improvements in all response domains (PtGA, spinal pain, function, and stiffness) as well as fatigue and spinal pain at night (p < 0.001). ASAS40 responses were associated with 3.5- to 48.0-fold greater improvements in these PROs, with the highest values for PtGA and function, compared to ASAS20 non-achievement. Conclusions As early as week 1, patients with nr-axSpA treated with ixekizumab reported significant improvements in PtGA, spinal pain, function, and stiffness compared with those taking placebo. ASAS40 responders reported significantly greater improvements in all ASAS response domains (PtGA, spinal pain, function, and stiffness) as well as fatigue and spinal pain at night than ASAS20 non-responders. Improvements in PtGA and function appear to be major drivers in achieving ASAS40 response in patients with nr-axSpA. Trial Registration NCT02757352.

Improvement of Signs and Symptoms of Nonradiographic Axial Spondyloarthritis in Patients Treated With Secukinumab: Primary Results of a Randomized, Placebo-Controlled Phase III Study. Arthritis Rheumatol 2020; 73:110-120.

Abstract
Objective To report the primary (1‐year) results from PREVENT, the first phase III study evaluating secukinumab in patients with active nonradiographic axial spondyloarthritis (SpA). Methods A total of 555 patients were randomized (1:1:1) to receive subcutaneous secukinumab 150 mg with a loading dose (loading dose [LD] group), secukinumab 150 mg without a loading dose (non–loading dose [NL] group), or placebo weekly and then every 4 weeks starting at week 4. The NL group received placebo at weeks 1, 2, and 3 to maintain blinding. Switch to open‐label secukinumab or standard of care was permitted after week 20. The study had 2 independent analysis plans, per European Union and non‐US (plan A; week 16) and US (plan B; week 52) regulatory requirements. The primary end point was 40% improvement in disease activity according to the Assessment of SpondyloArthritis international Society (ASAS40) criteria at week 16 (in the LD group) and at week 52 (in the NL group) in tumor necrosis factor inhibitor (TNFi)–naive patients. Safety analyses included all patients who received ≥1 dose of study treatment. Results Overall, 481 patients completed 52 weeks of treatment, including 84.3% (156 of 185) in the LD group, 89.7% (165 of 184) in the NL group, and 86.0% (160 of 186) in the placebo group. The proportion of patients who switched to open‐label or standard of care between weeks 20 and 48 was 50.8% in the LD group, 47.3% in the NL group, and 64.0% in the placebo group. Both primary and all secondary end points were met at week 16. The proportion of TNFi‐naive patients who met ASAS40 was significantly higher for LD at week 16 (41.5%) and NL at week 52 (39.8%) versus placebo (29.2% at week 16 and 19.9% at week 52; both P < 0.05). No new safety findings were reported. Conclusion Our findings indicate that secukinumab 150 mg provides significant and sustained improvement in signs and symptoms of nonradiographic axial SpA through 52 weeks. Safety was consistent with previous reports.

Abstract
Despite the publication of various recommendations, quality standards and referral strategies to promote early diagnosis in axial SpA (axSpA) over the last decade, there remains a significant delay to diagnosis, leading to a lost tribe of undiagnosed, untreated patients with persistent back pain and axSpA symptoms. This review discusses the various factors contributing to diagnostic delay in axSpA, while providing recommendations to improve the diagnostic pathway, for example use of the online Spondyloarthritis Diagnosis Evaluation (SPADE) tool (http://www.spadetool.co.uk/). Significant shortcomings exist at both the primary and secondary care level, with healthcare professionals often lacking knowledge and awareness of axSpA. Myths regarding the classical signs and symptoms still prevail, including the perception of axSpA as a male disease, only occurring in individuals who are HLA-B27 positive with raised inflammatory markers. Individuals within this lost tribe of undiagnosed patients are likely lacking adequate treatment and are thereby at risk of worse clinical outcomes. It is therefore vital that public health initiatives are implemented to improve education of healthcare professionals and to ensure early specialist referral, to ultimately improve the lives of patients with axSpA.

Abstract
The concept of axial spondyloarthritis (axSpA) encompasses both non-radiographic (nr-axSpA) and traditional radiographic axSpA (r-axSpA) forms. The former was conceived following the establishment of the ASAS classification criteria for axSpA, which for the first time included the use of magnetic resonance imaging of the sacroiliac joints. This facilitated the classification of patients with axSpA who did not present substantial structural damage. This conception of nr-axSpA revolutionized the classical understanding of axSpA opening new doors for research and broadening the scope of treatment to the entire spectrum of axSpA. In this sense, epidemiologic patterns of the disease were viewed anew, and early diagnosis became a primary objective in the management of the disease. However, despite these advances, this new axSpA subtype led to some concerns within the scientific community. These issues have been addressed by several studies that set out to clarify the concept of nr-axSpA. In this review, we summarize the findings of the most relevant studies including nr-axSpA and then discuss recent advances in understanding disease clinical patterns, burden of disease, and treatment effects. Current scientific research has shown subtle differences between nr-axSpA and r-axSpA. In the near future, these advances will allow for better management of individual patients across the axSpA spectrum.
