Background and Objective: Secukinumab, an anti-interleukin (IL)-17A monoclonal antibody, has demonstrated low radiographic progression over 4 years in patients with ankylosing spondylitis (AS). An adalimumab (tumor necrosis factor [TNF] inhibitor) biosimilar, GP2017 (SDZ-ADL; Sandoz), has been approved by the European Medicines Agency (July 2018) for use in all same indications as adalimumab, including AS. Adalimumab has also shown low long-term radiographic progression in patients with AS. Direct comparison of radiographic progression in AS between IL-17A and TNF inhibitors has not been studied. SURPASS is the first head-to-head, Phase IIIb, randomized, biologic-controlled study in AS to compare effects of secukinumab versus SDZ-ADL on spinal radiographic progression. Methods: Overall, 858 biologic-naïve patients with AS with elevated high-sensitivity C-reactive protein (≥ 5 mg/L) and/or at least one syndesmophyte in the cervical/lumbar spine at baseline (without total ankylosis) were randomized (1:1:1) to subcutaneous (sc) secukinumab (300 or 150 mg) or SDZ-ADL (40 mg). Secukinumab will be administered at baseline, weeks 1, 2, 3, and 4, and then every 4 weeks until week 100. SDZ-ADL will be administered every 2 weeks from baseline until week 102. Patients and investigators will be unblinded to drug but blinded to secukinumab doses. Spinal X-rays will be obtained at baseline, and weeks 52 and 104, sacroiliac joint (SIJ) X-rays at baseline and week 104, and magnetic resonance imaging (MRI) of SIJs and spine at baseline, weeks 16, 52, and 104. The primary endpoint is to demonstrate superiority of secukinumab (300 or 150 mg) treatment versus SDZ-ADL regarding proportion of patients with no radiographic progression (change from baseline in modified Stoke Ankylosing Spondylitis Spinal Score [mSASSS] ≤ 0.5) at week 104. Secondary endpoints include change from baseline in mSASSS, proportion of patients with syndesmophyte at baseline who develop no new syndesmophytes, reduction of osteitis on MRI of SIJs and spine (Berlin method). Assessment of SpondyloArthritis International Society (ASAS) 20/40 responses, ASAS partial remission, and AS Disease Activity Score (ASDAS) inactive disease (ASDAS < 1.3) in secukinumab- versus SDZ-ADL-treated patients at week 104. Conclusion: This is the first study designed to evaluate superiority of an IL-17A inhibitor, secukinumab, over a TNF inhibitor, SDZ-ADL, in reducing spinal radiographic progression in AS.

Patients with axial spondyloarthritis (axSpA) frequently report pain, stiffness, fatigue, and sleep problems, which may lead to impaired physical activity. The majority of reported-on measures evaluating physical activity and sleep disturbance in axSpA are self-reported questionnaires, which can be impacted by patient recall (reporting bias). One objective measure, polysomnography, has been employed to evaluate sleep in patients with axSpA; however, it is an intrusive measure and cannot be used over the long term. More convenient objective measures are therefore needed to allow for the long-term assessment of both sleep and physical activity in patients' daily lives. Wearable technology that utilizes actigraphy is increasingly being used for the objective measurement of physical activity and sleep in various therapy areas, as it is unintrusive and suitable for continuous tracking to allow longitudinal assessment. Actigraphy characterizes sleep disruption as restless movement while sleeping, which is particularly useful when studying conditions such as axSpA in which chronic pain and discomfort due to stiffness may be evident. Studies have also shown that actigraphy can effectively assess the impact of disease on physical activity. More research is needed to establish the usefulness of objective monitoring of sleep and physical activity specifically in axSpA patients over time. This review summarizes the current perspectives on physical activity and sleep quality in patients with axSpA, and the possible role of actigraphy in the future to more accurately evaluate the impact of treatment interventions on sleep and physical activity in axSpA.

Background: Patients with spondyloarthritis with radiographic sacroiliitis are traditionally classified according to the modified New York (mNY) criteria as ankylosing spondylitis (AS) and more recently according to the Assessment of SpondyloArthritis international Society (ASAS) criteria as radiographic axial spondyloarthritis (r-axSpA).Objective: To investigate the agreement between the mNY criteria for AS and the ASAS criteria for r-axSpA and reasons for disagreement.Methods: Patients with back pain ≥3 months diagnosed as axSpA with radiographic sacroiliitis (mNY radiographic criterion) were selected from eight cohorts (ASAS, Esperanza, GESPIC, OASIS, Reuma.pt, SCQM, SPACE, UCSF). Subsequently, we calculated the percentage of patients who fulfilled the ASAS r-axSpA criteria within the group of patients who fulfilled the mNY criteria and vice versa in six cohorts with complete information.Results: Of the 3882 patients fulfilling the mNY criteria, 93% also fulfilled the ASAS r-axSpA criteria. Inversely, of the 3434 patients fulfilling the ASAS r-axSpA criteria, 96% also fulfilled the mNY criteria. The main cause for discrepancy between the two criteria sets was the reported age at onset of back pain.Conclusion: Almost all patients with axSpA with radiographic sacroiliitis fulfil both ASAS and mNY criteria, which supports the interchangeable use of the terms AS and r-axSpA.

Objective: The natural history of nonradiographic axial spondyloarthritis (SpA) is incompletely characterized, and there are concerns that nonsteroidal antiinflammatory drugs provide inadequate disease control in patients with active disease. This study was undertaken to investigate the effects of certolizumab pegol (CZP), an anti–tumor necrosis factor treatment, in patients with nonradiographic axial SpA with objective signs of inflammation. Methods: In this ongoing parallel‐group double‐blind study, adults with active disease were recruited from 80 centers in Australia, Europe, North America, and Taiwan, and were randomized 1:1 to receive placebo or CZP (400 mg at weeks 0, 2, and 4, followed by 200 mg every 2 weeks) in addition to nonbiologic background medication (NBBM). Switching to open‐label CZP (or other biologic) or making background medication changes was permitted at any point during the trial, although changes before week 12 were discouraged. The primary end point was the proportion of patients achieving major improvement (MI) (i.e., a ≥2.0‐point decrease in the score from baseline or achievement of the lowest possible score [0.6]) in the Ankylosing Spondylitis Disease Activity Score (ASDAS) at week 52. Results: A total of 317 patients were randomized to receive placebo plus NBBM (n = 158) or CZP plus NBBM (n = 159). ASDAS‐MI at week 52 was achieved in 47.2% (75 of 159) of CZP plus NBBM patients, which was significantly greater (P < 0.0001) than the 7.0% (11 of 158) of placebo plus NBBM patients in whom ASDAS‐MI was achieved. Of the placebo plus NBBM patients, 60.8% (96 of 158) switched to open‐label treatment before week 52 compared to 12.6% (20 of 159) of the CZP plus NBBM patients. Conclusion: Adding CZP to background medication is superior to adding placebo in patients with active nonradiographic axial SpA. These results indicate that remission in nonradiographic axial SpA treated without biologics occurs infrequently, demonstrating the need for treatment beyond nonbiologic therapy.

Introduction: Theoretical risks of biologic agents remain under study.Objective: The aim of this study was to integrate 1-year safety data from 12 ustekinumab registrational trials.Methods: Patients had moderate-to-severe plaque psoriasis, active psoriatic arthritis (PsA) (± methotrexate), or moderate-to-severe Crohn's disease (CD; failed/intolerant of immunomodulators/corticosteroids). Psoriatic patients received subcutaneous ustekinumab 45/90 mg or placebo, generally at week 0, week 4, then every 12 weeks thereafter, while those with CD received a single intravenous ustekinumab dose (130 mg or weight range-based dosing of approximately 6 mg/kg) or placebo induction dose at week 0, followed by subcutaneous ustekinumab 90 mg at week 8 and every 8/12 weeks thereafter. The incidence rates of a priori-defined safety events were integrated post hoc (adjusted for duration of follow-up, reported per 100 patient-years [PYs]).Results: Among 6280 enrolled patients, 5884 ustekinumab-treated patients (psoriasis: 3117; PsA: 1018; CD: 1749) contributed 4521 PYs versus 674 PYs in placebo-treated patients through year 1 (829 PYs and 385 PYs during 8- to 16-week controlled periods). Combined across diseases among ustekinumab- versus placebo-treated patients, respective incidences/100 PYs (95% confidence intervals) of infections were 125.4 (122.2-128.7) versus 129.4 (120.9-138.3) through year 1, and not meaningfully increased in patients who did versus those who did not receive methotrexate (92.5 [84.2-101.5] vs. 115.3 [109.9-121.0]), or significantly increased in patients who did versus those who did not receive corticosteroids (116.3 [107.3-125.9] vs. 107.3 [102.0-112.8]) at baseline. Major adverse cardiovascular events (0.5 [0.3-0.7] vs. 0.3 [0.0-1.1]), malignancies (0.4 [0.2-0.6] vs. 0.2 [0.0-0.8]), and deaths (0.1 [0.0-0.3] vs. 0.0 [0.0-0.4]) were rare across indications.Conclusions: Ustekinumab demonstrated a favorable and consistent safety profile across registrational trials in approved indications.Trial Registrations: ClinicalTrials.gov identifier: NCT00320216, NCT00267969, NCT00307437, NCT00454584, NCT00267956, NCT01009086, NCT01077362, NCT00265122, NCT00771667, NCT01369329, NCT01369342, and NCT01369355.

Objective: To examine associations of HLA class I and class II alleles with ankylosing spondylitis (AS) in three cohorts of patients of European, Asian and African ancestry.Methods: HLA-A, HLA-B, HLA-C, HLA-DRB1, HLA-DQB1 and HLA-DPB1 alleles were genotyped in 1948 unrelated white and 67 African-American patients with AS from the Prospective Study of Outcomes in Ankylosing Spondylitis cohort, the North American Spondylitis Consortium and Australo-Anglo-American Spondyloarthritis Consortium, 990 white and 245 African-American Controls and HLA-B alleles in 442 Han Chinese patients with AS and 346 controls from Shanghai and Gansu, China. In addition to the case:control analyses, HLA-B*27-negative patients with AS were analysed separately, and logistic regression and 'relative predispositional effects' (RPE) analyses were carried out to control for the major effect of HLA-B*27 on disease susceptibility.Results: Although numerous associations were seen between HLA alleles and AS in whites, among HLA-B*27-negative patients with AS , positive associations were seen with HLA-A*29, B*38, B*49, B*52, DRB1*11 and DPB1*03:01 and negative associations with HLA-B*07, HLA-B*57, HLA-DRB1*15:01, HLA-DQB1*02:01 and HLA-DQB1*06:02. Additional associations with HLA-B*14 and B*40 (B60) were observed via RPE analysis, which excludes the HLA-B*27 alleles. The increased frequency of HLA-B*40:01 and decreased frequency of HLA-B*07 was also seen in Han Chinese and African-Americans with AS. HLA-B*08 was decreased in whites with acute anterior uveitis.Conclusions: These data, analysing the largest number of patients with AS examined to date in three ethnic groups, confirm that other HLA class I and II alleles other than HLA-B*27 to be operative in AS predisposition.

Therapeutic targets have been defined for axial and peripheral spondyloarthritis (SpA) in 2012, but the evidence for these recommendations was only of indirect nature. These recommendations were re-evaluated in light of new insights. Based on the results of a systematic literature review and expert opinion, a task force of rheumatologists, dermatologists, patients and a health professional developed an update of the 2012 recommendations. These underwent intensive discussions, on site voting and subsequent anonymous electronic voting on levels of agreement with each item. A set of 5 overarching principles and 11 recommendations were developed and voted on. Some items were present in the previous recommendations, while others were significantly changed or newly formulated. The 2017 task force arrived at a single set of recommendations for axial and peripheral SpA, including psoriatic arthritis (PsA). The most exhaustive discussions related to whether PsA should be assessed using unidimensional composite scores for its different domains or multidimensional scores that comprise multiple domains. This question was not resolved and constitutes an important research agenda. There was broad agreement, now better supported by data than in 2012, that remission/inactive disease and, alternatively, low/minimal disease activity are the principal targets for the treatment of PsA. As instruments to assess the patients on the path to the target, the Ankylosing Spondylitis Disease Activity Score (ASDAS) for axial SpA and the Disease Activity index for PSoriatic Arthritis (DAPSA) and Minimal Disease Activity (MDA) for PsA were recommended, although not supported by all. Shared decision-making between the clinician and the patient was seen as pivotal to the process. The task force defined the treatment target for SpA as remission or low disease activity and developed a large research agenda to further advance the field. [ABSTRACT FROM AUTHOR]

Objective To identify genetic associations with severity of radiographic damage in ankylosing spondylitis (AS). Method We studied 1537 AS cases of European descent; all fulfilled the modified New York Criteria. Radiographic severity was assessed from digitised lateral radiographs of the cervical and lumbar spine using the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS). A two-phase genotyping design was used. In phase 1, 498 single nucleotide polymorphisms (SNPs) were genotyped in 688 cases; these were selected to capture >90% of the common haplotypic variation in the exons, exon-intron boundaries, and 5 kb flanking DNA in the 50 and 30 UTR of 74 genes involved in anabolic or catabolic bone pathways. In phase 2, 15 SNPs exhibiting p<0.05 were genotyped in a further cohort of 830 AS cases; results were analysed both separately and in combination with the discovery phase data. Association was tested by contingency tables after separating the samples into 'mild' and 'severe' groups, defined as the bottom and top 40% by mSASSS, adjusted for gender and disease duration. Results Experiment-wise association was observed with the SNP rs8092336 (combined OR 0.32, p=1.2x10-5), which lies within RANK (receptor activator of NFκB), a gene involved in osteoclastogenesis, and in the interaction between T cells and dendritic cells. Association was also found with the SNP rs1236913 in PTGS1 (prostaglandin-endoperoxide synthase 1, cyclooxygenase 1), giving an OR of 0.53 (p=2.6x10-3). There was no observed association between radiographic severity and HLA-B*27. Conclusions These findings support roles for bone resorption and prostaglandins pathways in the osteoproliferative changes in AS. [ABSTRACT FROM AUTHOR]

Objective The human major histocompatibility complex class I chain-related gene A (MICA) controls the immune process by balancing activities of natural killer cells, γδ T cells and αβ CD8 T cells, and immunosuppressive CD4 T cells. MICA is located near HLA-B on chromosome 6. Recent genomewide association studies indicate that genes most strongly linked to ankylosing spondylitis (AS) susceptibility come from the region containing HLA-B and MICA. While HLA-B27 is a well-known risk genetic marker for AS, the potential effect of linkage disequilibrium (LD) shields any associations of genes around HLA-B with AS. The aim of this study was to investigate a novel independent genetic association of MICA to AS. Methods We examined 1543 AS patients and 1539 controls from two ethnic populations by sequencing MICA and genotyping HLA-B alleles. Initially, 1070 AS patients and 1003 controls of European ancestry were used as a discovery cohort, followed by a confirmation cohort of 473 Han Chinese AS patients and 536 controls. We performed a stratified analysis based on HLA-B27 carrier status. We also conducted logistic regression with a formal interaction term. Results Sequencing of MICA identified that MICA*007:01 is a significant risk allele for AS in both Caucasian and Han Chinese populations, and that MICA*019 is a major risk allele in Chinese AS patients. Conditional analysis of MICA alleles on HLA-B27 that unshielded LD effect confirmed associations of the MICA alleles with AS. Conclusions Parallel with HLA-B27, MICA confers strong susceptibility to AS in US white and Han Chinese populations. [ABSTRACT FROM AUTHOR]

Objective To develop and validate a reference image module aimed at calibration of readers using the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS) to assess radiographic progression in spondyloarthritis. Methods Our working group comprised 6 rheumatologists and 3 musculoskeletal radiologists. The following developmental steps were conducted: 1) review of the literature to identify aspects of the mSASSS requiring methodologic clarity; 2) independent assessment of baseline and 2-year radiographs from 25 patients using the mSASSS (pilot exercise); 3) development of a training module (the Spondyloarthritis Radiography [SPAR] module) that clarifies definitions, rules, and scoring methodology and a set of reference radiographic images; 4) scoring exercise 1 by 6 readers on 39 patients, where baseline and 2-year radiographs were scored blinded to time point; and 5) revision of the SPAR module followed by scoring exercise 2 conducted by the same 6 readers on 35 patients. Reliability of status and 2-year change scores was assessed by the intraclass correlation coefficient (ICC) method. Results ICCs for change scores for the radiologist reader pair improved from 0.46 to 0.62 after minimal calibration with the SPAR module. Recalibration from exercise 1 to exercise 2 with the SPAR module led to substantial improvement in interreader reliability for change in mSASSS score from ICC 0.44 (range 0.31-0.62) to ICC 0.62 (range 0.34-0.84). Simultaneous assessment of anteroposterior and lateral lumbar radiographs did not enhance reliability or detection of progression. Conclusion Calibration according to the SPAR module led to improved reliability in the scoring of the mSASSS, even for expert readers. [ABSTRACT FROM AUTHOR]

Objective: Spinal radiographic progression is an important outcome in radiographic axial spondyloarthritis (SpA). The objective of the phase IIIb SURPASS study was to compare spinal radiographic progression in patients with radiographic axial SpA treated with secukinumab (interleukin‐17A inhibitor) versus adalimumab biosimilar (Sandoz adalimumab [SDZ‐ADL]; tumor necrosis factor inhibitor). Methods: Biologic‐naive patients with active radiographic axial SpA, at high risk of radiographic progression (high‐sensitivity C‐reactive protein [hsCRP] ≥5 mg/L and/or ≥1 syndesmophyte[s] on spinal radiographs), were randomized (1:1:1) to secukinumab (150/300 mg) or SDZ‐ADL (40 mg). The proportion of patients with no radiographic progression (change from baseline [CFB] in modified Stoke Ankylosing Spondylitis Spinal Score [mSASSS] ≤0.5) on secukinumab versus SDZ‐ADL at week 104 (primary endpoint), mean CFB‐mSASSS, proportion of patients with ≥1 syndesmophyte(s) at baseline with no new syndesmophyte(s), and safety were evaluated. Results: Overall, 859 patients (78.5% male, mSASSS 16.6, Bath Ankylosing Spondylitis Disease Activity Index 7.1, hsCRP 20.4 mg/L, and 73.0% with ≥1 syndesmophyte[s]) received secukinumab 150 mg (n = 287), secukinumab 300 mg (n = 286), or SDZ‐ADL (n = 286). At week 104, the proportion of patients with no radiographic progression was 66.1%, 66.9%, and 65.6% (P = not significant, both secukinumab doses) and mean CFB‐mSASSS was 0.54, 0.55, and 0.72 in secukinumab 150 mg, secukinumab 300 mg, and SDZ‐ADL arms, respectively. Overall, 56.9%, 53.8%, and 53.3% of patients on secukinumab 150 mg, secukinumab 300 mg, and SDZ‐ADL, respectively, with ≥1 syndesmophyte(s) at baseline did not develop new syndesmophyte(s) by week 104. There were no unexpected safety findings. Conclusion: Spinal radiographic progression over two years was low with no significant difference between secukinumab and SDZ‐ADL arms. The safety of both treatments was consistent with previous reports. [ABSTRACT FROM AUTHOR]

Introduction: This integrated analysis of the phase 2/3 and phase 3 SELECT trials describes the safety profile of upadacitinib, an oral Janus kinase inhibitor, for up to 5 years of exposure across psoriatic arthritis (PsA), ankylosing spondylitis (AS), and non-radiographic axial spondyloarthritis (nr-axSpA) (including pooled axial spondyloarthritis [axSpA]). Methods: Safety data from five trials of upadacitinib in PsA (2 trials), AS (2 trials), and nr-axSpA (1 trial) were analyzed up to a data cut-off of August 15, 2022. One PsA study included adalimumab as an active comparator. Treatment-emergent adverse events (TEAEs) were summarized for PsA (pooled upadacitinib 15 mg once daily and adalimumab 40 mg biweekly), AS (pooled upadacitinib 15 mg), nr-axSpA (upadacitinib 15 mg), and pooled axSpA (pooled upadacitinib 15 mg from axSpA trials). TEAEs were reported as exposure-adjusted event rates per 100 patient-years (E/100 PY). Results: A total of 1789 patients (PsA, n = 907; AS, n = 596; nr-axSpA, n = 286) received ≥ 1 dose of upadacitinib 15 mg for 3689 PY of exposure or adalimumab (n = 429) for 1147 PY of exposure. Overall TEAEs and serious TEAEs were highest in PsA and numerically higher with upadacitinib versus adalimumab; rates were similar between AS and nr-axSpA. In PsA, higher rates of serious infection, herpes zoster (HZ), lymphopenia, and nonmelanoma skin cancer (NMSC) were observed with upadacitinib versus adalimumab. Rates of malignancy excluding NMSC, adjudicated major adverse cardiovascular events, and adjudicated venous thromboembolic events were comparable between upadacitinib and adalimumab in PsA and were similar across diseases. Conclusion: Higher rates of serious infection, HZ, lymphopenia, and NMSC were observed with upadacitinib versus adalimumab in PsA; slightly elevated rates for most of these TEAEs were seen with upadacitinib in PsA versus axSpA. Upadacitinib 15 mg demonstrated a generally consistent safety profile across disease states with no new safety signals identified. Trial Registration: SELECT-AXIS 1: NCT03178487; SELECT-AXIS 2: NCT04169373; SELECT-PsA 1: NCT03104400; SELECT-PsA 2: NCT03104374. Plain Language Summary: Psoriatic arthritis, ankylosing spondylitis, and non-radiographic axial spondyloarthritis are a group of diseases that cause pain and inflammation of the joints and/or spine. Safety data were combined from five studies: two in psoriatic arthritis, two in ankylosing spondylitis, and one in non-radiographic axial spondyloarthritis. Patients were treated with upadacitinib or adalimumab for up to 5 years. Adalimumab was only used for patients participating in one of the two psoriatic arthritis studies. Side effects from treatment were more common in patients with psoriatic arthritis than those with ankylosing spondylitis and non-radiographic axial spondyloarthritis; more patients with psoriatic arthritis had side effects with upadacitinib than adalimumab. A similar number of patients across treatment groups and diseases had side effects that made them stop treatment. The number of cancer cases (except cancer of the upper layer of the skin), cardiovascular issues, and blood clots were similar between the upadacitinib and adalimumab groups in psoriatic arthritis and across diseases. Serious infections, painful rashes that cause blisters (herpes zoster, also commonly referred to as shingles), low levels of white blood cells, and cancer of the upper layer of the skin were more common with upadacitinib than adalimumab in patients with psoriatic arthritis; overall, these events occurred more often with upadacitinib in patients with psoriatic arthritis than with ankylosing spondylitis and non-radiographic axial spondyloarthritis. Our results showed that the safety of upadacitinib was generally similar across diseases, and patients could tolerate it well for up to 5 years. No new safety risks were found with upadacitinib treatment. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
