Abstract
OBJECTIVE AS is a rheumatic disease characterized by chronic inflammation and bony ankylosis. This study was to evaluate whether a signal transducer and activator of transcription 3 phosphorylation inhibitor (stat3-p Inh) could treat both chronic inflammation and bone formation in AS. METHODS Primary AS osteoprogenitor cells and spinal entheseal cells were examined for osteogenic differentiation. SF mononuclear cells (SFMCs) and lamina propria mononuclear cells (LPMCs) were obtained from AS patients. Inflammatory cytokine-producing cells were analysed using flow cytometry and ELISA. Female SKG mice were treated with stat3-p Inh, IL-17A blocker or vehicle. Inflammation and new bone formation were evaluated using immunohistochemistry, PET and micro-CT. RESULTS In the SKG mouse model, stat3-p Inh significantly suppressed arthritis, enthesitis, spondylitis and ileitis. In experiments culturing SFMCs and LPMCs, the frequencies of IFN-γ-, IL-17A- and TNF-α-producing cells were significantly decreased after stat3-p Inh treatment. When comparing current treatments for AS, stat3-p Inh showed a comparable suppression effect on osteogenesis to Janus kinase inhibitor or IL-17A blocker in AS-osteoprogenitor cells. Stat3-p Inh suppressed differentiation and mineralization of AS-osteoprogenitor cells and entheseal cells toward osteoblasts. Micro-CT analysis of hind paws revealed less new bone formation in stat3-p Inh-treated mice than vehicle-treated mice (P = 0.005). Hind paw and spinal new bone formation were similar between stat3-p Inh- and anti-IL-17A-treated SKG mice (P = 0.874 and P = 0.117, respectively). CONCLUSION Stat-3p inhibition is a promising treatment for both inflammation and new bone formation in AS.

Abstract
Since the birth of biotechnology, hundreds of biotherapeutics have been developed and approved by the US Food and Drug Administration (FDA) for human use. These novel medicines not only bring significant benefit to patients but also represent precision tools to interrogate human disease biology. Accordingly, much has been learned from the successes and failures of hundreds of high-quality clinical trials. In this review, we discuss general and broadly applicable themes that have emerged from this collective experience. We base our discussion on insights gained from exploring some of the most important target classes, including interleukin-1 (IL-1), tumor necrosis factor α (TNF-α), IL-6, IL-12/23, IL-17, IL-4/13, IL-5, immunoglobulin E (IgE), integrins and B cells. We also describe current challenges and speculate about how emerging technological capabilities may enable the discovery and development of the next generation of biotherapeutics.

Abstract
INTRODUCTION Interleukin 17 is a proinflammatory cytokine considered to play a significant role in the immunopathogenesis of many chronic immune-mediated disorders. Interleukin 17 inhibitors provide an excellent treatment option for patients with psoriasis, psoriatic arthritis, or ankylosing spondylitis. However, Interleukin 17 inhibitors have been suspected of worsening or triggering new-onset inflammatory bowel disease. AREAS COVERED A literature search was conducted until March 2021 to investigate reporting prevalence, and characteristics of all gastroenterological adverse events in patients treated with Interleukin 17 inhibitors. One hundred and six clinical randomized trials were included, involving 40,053 patients. Inflammatory bowel disease cases were reported in 0.4% of patients exposed to Interleukin 17 inhibitors. The most frequent other gastrointestinal adverse events were diarrhea (2.5%), nausea or vomiting (0.7%), and gastroenteritis (0.2%). Sixty-one uncontrolled or retrospective studies were included, involving 16,791 patients. Sixty (0.36%) inflammatory bowel disease cases were reported, 0.6% of patients reported other gastrointestinal adverse events. EXPERT OPINION Interleukin 17 inhibitors are safe and effective in the treatment of psoriasis, psoriatic arthritis, and ankylosing spondylitis. Low incidence rate of developing new-onset inflammatory bowel disease or exacerbating preexisting inflammatory bowel disease with anti-IL-17 agents has been reported. Clinicians should be aware of the possibility of these concerns when considering this therapy.

Abstract
PURPOSE OF REVIEW Axial spondyloarthritis (axSpA) affects 0.5-1% of the population in many regions of the world. This review summarizes the challenges in medical education around axSpA with attention to evidence around delayed diagnosis, clinician familiarity with typical axSpA features, such as inflammatory back pain and adherence to accepted management principles. RECENT FINDINGS Clinicians who commonly manage patients with chronic back pain or other typical axSpA features are not consistently aware of the concept of inflammatory back pain and common extra-spinal manifestations. Further, clinicians may not be familiar with the nonradiographic spectrum of axSpA. Management of patients with possible axSpA does not consistently follow principles that would establish an axSpA diagnosis, and diagnosis of axSpA remains delayed by 6-7 years on average, with evidence suggesting management disparities on the basis of sex and race in some cases. Referral recommendations have increased the probability of axSpA diagnosis up to about 40% and, may complement educational efforts in axSpA. SUMMARY Educational efforts in axSpA should focus on providing front-line clinicians with a better understanding of inflammatory back pain, the nonradiographic form of axSpA, and accepted principles in axSpA management.

Abstract
PURPOSE OF REVIEW The last decade has witnessed tremendous advances in revealing an important role for the interleukin (IL)-17 cytokine family in the pathogenesis of spondyloarthritis (SpA). Although most attention has been focused on IL-17A, a potential role of other IL-17 family members in inflammation and tissue remodelling is emerging. Herein, I review recent studies covering the role of IL-17B-F cytokines in the pathogenesis of SpA. RECENT FINDINGS Several recent studies provided new insights into the cellular source, regulation and function of IL-17F. IL-17F/IL-17A expression ratio is higher in psoriatic skin compared to SpA synovitis. IL-17F-expressing T cells produce different proinflammatory mediators than IL-17A-expressing cells, and IL-17F and IL-17A signal through different receptor complex. Dual IL-17A and IL-17F neutralization resulted in greater suppression of downstream inflammatory and tissue remodelling responses. Furthermore, there is additional evidence of IL-23-independent IL-17 production. In contrast to IL-17A, IL-17F and IL-17C, which play proinflammatory roles in skin and joint inflammation, an anti-inflammatory function is proposed for IL-17D. An increase in IL-17E is associated with subclinical gut microbiome alterations after anti-IL-17A therapy in SpA patients. SUMMARY IL-17 family cytokines may act as agonists or antagonists to IL-17A contributing in concert to local inflammatory responses. Understanding their function and identifying their cellular sources, and molecular mechanisms driving their expression will be the key to designing rational therapies in SpA.

Abstract
Psoriasis, psoriatic arthritis, and axial spondyloarthritis are systemic inflammatory diseases, each commonly manifesting as a spectrum of symptoms, complications, and comorbidities that arise differently in individual patients. Drugs targeting inflammatory cytokines common to the pathogenesis of each of these conditions have been developed, although their specific actions in the different tissues involved are variable. For a drug to be effective, it must be efficiently delivered to and locally bioactive in disease-relevant tissues. Detailed clinical data shed light on the therapeutic effects of individual biologics on specific domains or clinical manifestations of disease and assist in guiding treatment decisions. Pharmacologic, molecular, and functional properties of drugs strongly impact their observed safety and efficacy, and an understanding of these properties provides complementary insight. Secukinumab, a fully human monoclonal IgG1/κ antibody selectively targeting interleukin (IL)-17A, has been in clinical use for >6 years in the treatment of moderate to severe psoriasis, psoriatic arthritis, and both radiographic (also known as ankylosing spondylitis) and nonradiographic axial spondyloarthritis. In this review, we discuss pharmacokinetic and pharmacodynamic data for secukinumab to introduce clinicians to the pharmacological properties of this widely used drug. Understanding how these properties affect the observed clinical efficacy, safety, and tolerability of this drug in the treatment of IL-17A-mediated systemic inflammatory diseases is important for all physicians treating these conditions.

Abstract
OBJECTIVES Interleukin (IL)-17 signalling has been shown to be a key regulator of disease in ankylosing spondylitis (AS) with several IL-17 blockers currently clinically approved. Despite this, the role of IL-17 in bone pathology is poorly understood. This study aimed to investigate IL-17 signalling in the context of pathological bone formation. METHODS A biomimetic human periosteum-derived cell (hPDC) model of osteogenic differentiation was used in combination with recombinant IL-17 cytokines, T-cell supernatants or serum from patients with AS. IL-17A, IL-17F and bimekizumab monoclonal antibodies were used to block IL-17 cytokine action. RESULTS Recombinant IL-17A and IL-17F are pro-osteogenic with respect to hPDC differentiation. T helper 17 or γδ-T cell supernatants also potently stimulated in vitro bone formation, which was blocked deeper by dual inhibition of IL-17A and IL-17F than by neutralisation of IL-17A or IL-17F individually. Osteogenic blockade may be due to an increase in expression of the Wnt antagonist DKK1. Interestingly, osteocommitment was also induced by serum obtained from patients with AS, which was also abrogated by dual neutralisation of IL-17A and IL-17F. CONCLUSIONS These data show for the first time that IL-17A and IL-17F enhance in vitro osteogenic differentiation and bone formation from hPDCs, inhibition of which may offer an attractive therapeutic strategy to prevent pathological bone formation.

Abstract
Spondyloarthritis (SpA) encompasses a broad spectrum of conditions occurring from childhood to middle age. Key features of SpA include axial and peripheral arthritis, enthesitis, extra-articular manifestations, and a strong association with HLA-B27. These features are common across the ages but there are important differences between juvenile and adult onset disease. Juvenile SpA predominantly affects the peripheral joints and the incidence of axial arthritis increases with age. Enthesitis is important in early disease. This review article highlights the similarities and differences between juvenile and adult SpA including classification, pathogenesis, clinical features, imaging, therapeutic strategies, and disease outcomes. In addition, the impact of the biological transition from childhood to adulthood is explored including the importance of musculoskeletal and immunological maturation. We discuss how the changes associated with adolescence may be important in explaining age-related differences in the clinical phenotype between juvenile and adult SpA and their implications for the treatment of juvenile SpA.

Abstract
PURPOSE OF REVIEW To give an overview of the recently published trials relating to IL-23/IL-17 pathway in spondyloarthritis (SpA). RECENT FINDINGS Recent studies in psoriasis confirmed the efficacy of targeting the IL-23/IL-17 pathway, with emerging evidence from head-to-head studies suggesting functional hierarchy of these inhibitors. In psoriatic arthritis (PsA), recent studies have indicated the efficacy of inhibiting IL-23p19, in addition to IL-23p40 and IL-17A, albeit all with lower hurdle results than those seen in psoriasis. The first head-to-head study of an IL-17A and tumour necrosis factor inhibitor in PsA has also recently been published. Recent studies have demonstrated the efficacy of the IL-17A inhibitor, ixekizumab, across the axial SpA spectrum. In contrast, inhibition of IL-12/IL-23p40 and IL-23p19 both failed in axial SpA. In inflammatory bowel disease (IBD), recent studies indicate efficacy of IL-23p40 and IL-23p19 inhibition, in contrast to the previous failed studies of IL-17 inhibition. SUMMARY Clinical trials of IL-23/IL-17 inhibition have been transformative in psoriasis, with more mixed results in PsA and differential responses in axial SpA and IBD. These results pose challenges to our fundamental understanding of SpA pathogenesis and further head-to-head studies and more subtle evaluation of the local tissue-specific aspects will be required.

Abstract
PURPOSE OF REVIEW Enthesitis is a cardinal feature of spondyloarthritis (SpA). Despite increasing available treatments, challenges remain in adequately controlling inflammation and subsequent new bone formation (NBF) in entheses; thus, a better understanding of the immunopathogenesis is warranted. RECENT FINDINGS Increasing evidence has identified immune cells playing key roles in enthesitis such as γδ T cells and group 3 innate lymphoid cells (ILC3), possibly with site-specific regulatory systems. The presence of T cells producing interleukin (IL)-17 independent of IL-23 in human spinal entheses was recently reported, which may corroborate the discrepancy between recent clinical trials and pre-clinical studies. In addition, the contribution of myeloid cells has also been focused in both human and pre-clinical SpA models. Moreover, not only the IL-23/IL-17 signaling, but other key type 3 immunity mediators, such as IL-22 and granulocyte-macrophage colony-stimulating factor (GM-CSF), have been reported as pivotal cytokines in inflammation and NBF of entheses. Immune cells demonstrating distinct features orchestrate entheses, leading to the complex landscape of enthesitis. However, recent advances in understanding the immunopathogenesis may provide new therapeutic targets and future research directions.

Abstract
OBJECTIVE To assess the efficacy of secukinumab on axial and peripheral enthesitis in patients with ankylosing spondylitis (AS) using pooled data from randomized controlled phase III studies. METHODS In this posthoc analysis, data were pooled from patients originally randomized to secukinumab 150 mg, 300 mg, or placebo (PBO) from phase III MEASURE 1-4 studies (ClinicalTrials.gov: NCT01358175, NCT01649375, NCT02008916, and NCT02159053). Maastricht AS Enthesitis Score (MASES) was used for assessments of enthesitis through Week 52. Efficacy outcomes were mean change in MASES score and complete resolution (MASES = 0) of enthesitis in patients with baseline MASES > 0. RESULTS A total of 693 (71.5%) patients had enthesitis at baseline in secukinumab 300 mg, 150 mg, and PBO groups (58 [76.3%], 355 [70.4%], and 280 [72%], respectively) out of 969 patients pooled in this analysis. At Week 16, mean changes from baseline for overall MASES and enthesitis at axial MASES sites, respectively, were as follows: -2.9 (P < 0.01) and -2.9 (P < 0.01) for secukinumab 300 mg; -2.4 (P < 0.015) and -2.3 (P < 0.05) for secukinumab 150 mg; and -1.9 and -1.8 for PBO, with improvements seen through Week 52. More than one-third of secukinumab-treated patients (300 mg: 36.2%; 150 mg: 40.8%) achieved complete resolution of enthesitis at Week 16. CONCLUSION Secukinumab improved enthesitis at overall MASES and axial sites in patients with AS.

Abstract
Heritability of Spondyloarthritis (SpA) is highlighted by several familial studies and a high association with the presence of human leukocyte antigen (HLA)-B*27. Though it has been over four decades since the association of HLA-B*27 with SpA was first determined, the pathophysiological roles played by specific HLA-B*27 allotypes are not fully understood. Popular hypotheses include the presentation of arthritogenic peptides, triggering of endoplasmic reticulum (ER) stress by misfolded HLA-B*27, and the interaction between free heavy chains or heavy chain homodimers of HLA-B*27 and immune receptors to drive IL-17 responses. Several non-HLA susceptibility loci have also been identified for SpA, including endoplasmic reticulum aminopeptidases (ERAP) and those related to the IL-23/IL-17 axes. In this review, we summarize clinical aspects of SpA including known characteristics of gut inflammation, enthesitis and new bone formation and the existing models for understanding the association of HLA-B*27 with disease pathogenesis. We also examine newer insights into the biology of HLA class I (HLA-I) proteins and their implications for expanding our understanding of HLA-B*27 contributions to SpA pathogenesis.

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
Introduction: Secukinumab is a fully human monoclonal antibody which targets and neutralizes interleukin (IL)-17A, a cytokine that plays an important role in the pathophysiology of ankylosing spondylitis (AS). Secukinumab is the first IL-17A inhibitor approved for the treatment of AS.Areas covered: This paper aimed to evaluate the role of IL-17 in human beings, and the blocking of this cytokine with secukinumab while reviewing its efficacy and safety in the treatment of AS from data of MEASURE clinical trials.Expert opinion: MEASURE clinical trials showed efficacy and safety of secukinumab in patients with AS. Mild infections were the most frequent adverse event observed. Mucocutaneous candidiasis was a relatively common side effect due to the role of IL-17A in mucocutaneous defense against extracellular organisms. Secukinumab remained generally well tolerated over the longer-term. The combination of efficacy and safety makes secukinumab a good option of treatment for patients with AS refractory to non-steroidal anti-inflammatory drugs.

Abstract
Among patients with axial spondyloarthritis (axSpA), non-radiographic axial spondyloarthritis (nr-axSpA) is distinguished from ankylosing spondylitis (AS) by a lack of obvious radiographic changes in the sacroiliac joint. Tumor necrosis factor inhibitor (TNFi) has been used as a highly effective treatment in patients with AS and has shown good efficacy and safety in clinical trials in patients with nr-axSpA. As the pathophysiological mechanism for axSpA has started to become better recognized, various drugs other than TNFi, all of which are related to the interleukin-17 (IL-17) axis, are being evaluated in patients with axSpA. IL-17 inhibitors, such as secukinumab and ixekizumab, are effective drugs for patients with AS. A recent clinical trial reported that ixekizumab, a monoclonal antibody against IL-17A, was also effective in patients with nr-axSpA. In a COAST-X study, ixekizumab was superior to a placebo for improving signs and symptoms in patients with nr-axSpA at weeks 16 and 52. The adverse events were no different from those found in previous ixekizumab studies, and no new safety signals were identified. However, when considering several IL-17 inhibitors, it is necessary to obtain sufficient data to identify the exacerbation of extra-articular manifestation. In terms of effectiveness and safety, ixekizumab may be an appropriate alternative to TNFi in nr-axSpA patients.

Abstract
To assess the efficacy and safety of interleukin (IL)-17A inhibitors in patients with ankylosing spondylitis (AS). PubMed, EMBASE, and Web of Science were searched up to 5 February 2020 for randomized controlled trials (RCTs) that assessed the efficacy and safety of IL-17A inhibitors in patients with AS. We used a meta-analytic approach to perform a random effects analysis or fixed effects analysis according to heterogeneity. Subgroup analyses between studies included medication, time to primary endpoint, and data source. Odds ratios (ORs) or mean differences (MDs) were used to assess the efficacy and safety of IL-17A inhibitors in AS. A total of ten RCTs with 2613 patients were eligible for inclusion in the analysis (six for secukinumab, two for ixekizumab, one for netakimab, and one for bimekizumab). Compared to placebo, IL-17A inhibitors improved ASAS20 response rate (OR = 2.58; p < 0.01) and ASAS40 response rate (OR = 2.80; p < 0.01), and significantly increased the risk of AEs (OR = 1.23; p = 0.03) and nasopharyngitis (OR = 1.72; p < 0.01), but not SAEs (OR = 0.87; p = 0.60). IL-17A inhibitors demonstrated better efficacy in patients with AS in several evaluation indicators. However, the safety of IL-17A inhibitors remains to be further studied in studies with larger sample size and longer follow-up times.

Achievement of Remission Endpoints with Secukinumab Over 3 Years in Active Ankylosing Spondylitis: Pooled Analysis of Two Phase 3 Studies. Rheumatol Ther 2020; 8:273-288. [PMID: 33351179 PMCID: PMC7991028 DOI: 10.1007/s40744-020-00269-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Accepted: 12/05/2020] [Indexed: 12/28/2022] Open
Abstract
Introduction Clinical remission in patients with ankylosing spondylitis (AS) has been determined using composite indices such as the AS Disease Activity Score inactive disease (ASDAS-ID), Assessment of SpondyloArthritis international Society criteria partial remission (ASAS-PR), and low Bath AS Disease Activity Index (BASDAI) scores. The objective of this exploratory analysis was to evaluate the proportion of secukinumab-treated patients with AS achieving remission defined based on the ASDAS-ID (score < 1.3), ASAS-PR or BASDAI score ≤ 2. Methods The analysis pooled data from the MEASURE 1 and 2 studies over 3 years. The proportion of patients who achieved ASDAS-ID, ASAS-PR, or BASDAI ≤ 2 with secukinumab was compared with placebo at week 16; results for secukinumab-treated patients were summarized through week 156. Sustainability of each criterion was assessed from week 16 to 156 using shift analysis. The association between each of these criteria and specific patient-reported outcomes (PROs), such as health-related quality of life, function, fatigue, and work impairment, was also explored. Results At week 16, a higher proportion of secukinumab-treated patients versus placebo achieved ASDAS-ID (17.6 vs. 3.5%), ASAS-PR (15.4 vs. 4.1%), or BASDAI ≤ 2 (22.3 vs. 6.4%) criteria (all P < 0.0001), which were sustained through 156 weeks. Shift analysis showed that the majority of secukinumab-treated patients achieving remission at week 16 maintained their status at week 156 (ASDAS-ID, 57.1%; ASAS-PR, 68.0% and BASDAI ≤ 2, 74.3%). Remission was also associated with improved PROs over 156 weeks. Conclusions Secukinumab-treated patients maintained ASDAS-ID, ASAS-PR, or BASDAI ≤ 2 from week 16 up to 3 years. Patients who achieved at least one of the three responses/states, reported improvement in PROs, which suggests an association of clinical remission/ID with PROs in patients with active AS.

Abstract
OBJECTIVES To analyse the predictive values of inflammatory back pain (IBP), positive HLA B27 antigen, increased C-reactive protein (CRP), Spondyloarthritis (SpA) features, familial history (FH), magnetic resonance sacroiliac joints (MRI-SIJ) imaging and its weight in early SpA diagnosis. METHODS 133 patients with back pain, aged <50, duration of the pain <2 years were included. Data such as IBP, HLA B27, increased CRP, SpA features, FH, SIJ´s radiography and MRI were collected for each patient. STIR sequences were classified as strongly positive bone morrow oedema (SPBME ≥2), clearly present and easily recognisable as positive according to the ASAS criterion, weakly positive (WPBME ≥2), suggestive, but not easily recognisable and, clearly negative none of those features. T1-weighted sequences were assessed as positive/negative for erosion, fat metaplasia, backfill and sclerosis, if ≥1, for each lesion was present. MRI images were read by three blinded readers. RESULTS The average age was 38.9 years. 47 (35.3%) patients received SpA diagnosis according to the clinical opinion. IBP was highly specific, 0.81 and sensitive, 0.83. HLA B27 was positive in a half of the SpA patients. SPBME ≥2 provided a great specificity, 0.94 and an acceptable sensitivity, 0.79. Erosion was significantly more frequent in SpA patients (72% vs 7%), specificity 0.93. The addition of erosion ≥1 to the WPBME ≥2 noticeably improved specificity, 0.98, although slightly decreased sensitivity, 0.64. Fat metaplasia and backfill were highly specific, but poorly sensitive. Factors forecasting positive diagnosis were IBP, followed by SpA features and increased CRP. CONCLUSIONS At the onset, IBP might be a good marker for selecting patients with suspicion of SpA. The addition of erosion to the ASAS criterion might be helpful for early diagnosis, especially in patients with doubtful STIR imaging where BME is present but it is hard to determinate whether the ASAS "highly suggestive" criterion is met.

Abstract
Objectives: The clinical benefit of conventional disease-modifying antirheumatic drugs (cDMARDs) for treating ankylosing spondylitis (AS) is generally limited to improvements in peripheral arthritis. However, cDMARDs could be conditionally considered as alternatives to established drugs for improving axial manifestations in exceptional circumstances. However, there are few studies of the impact of cDMARDs on radiographic progression outcomes. Therefore, we investigated the effectiveness of cDMARDs on radiographic progression in AS. Methods: Among 1280 AS patients at a single hospital from 2000 to 2018, 301 who had been treated with sulfasalazine (SSZ) or methotrexate (MTX) were enrolled. For each patient, the entire follow-up period was split into 1-year intervals. Each interval was classified as either an “on-cDMARD” interval, which was a period of treatment with SSZ alone, MTX alone, or a combination of SSZ and MTX, or an “off-cDMARD” interval, which was a period without cDMARD treatment. Radiographic progression was scored using the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS). The relationship between cDMARD use and radiographic progression within the intervals, defined as the rate of mSASSS progression, was investigated using linear models with adjustment for potential confounding covariates and for clustering among observations from the same patient. Results: The 732 on-cDMARD intervals and 1027 off-cDMARD intervals were obtained from enrolled patients. In multivariable regression analysis, there was no significant association between cDMARDs and the rate of mSASSS progression (β = −0.081, p = 0.418). The mean adjusted mSASSS change per year was 0.610 from on-cDMARD intervals and 0.691 from off-cDMARD intervals. Conclusion: Treatment with cDMARDs may not reduce radiographic progression in AS patients.

Abstract
Tumor necrosis factor inhibitor (TNFi) has been applied in the treatment of ankylosing spondylitis (AS) for many years but still with an unmed need due to inefficacy or intolerance. Current treatment guideline recommended the use of IL-17 inhibitors over a second TNFi in patients with primary nonresponse to the first TNFi. We herein review the present available IL-17 inhibitors including secukinumab (SEC), ixekizumab (IXE), brodalumab and bimekizumab (BKZ) in clinical trials of AS. Therapeutic response and safe profile have been discussed in detail for each drug. Overall, IL-17 inhibitors were proved to be alternatives for biologic disease-modifying anti-rheumatic drugs (bDMARDs) in AS, which might be safer for tuberculosis while candida infection should be monitored in long term treatment.

Abstract
The breadth of bone lesion types seen in spondyloarthritis is unprecedented in
medicine and includes increased bone turnover, bone loss and fragility,
osteitis, osteolysis and erosion, osteosclerosis, osteoproliferation of soft
tissues adjacent to bone and spinal skeletal structure weakness. Remarkably,
these effects can be present simultaneously in the same patient. The search for
a potential unifying cause of effects on the skeleton necessarily focuses on
inflammation arising from the dysregulation of immune response to
microorganisms, particularly dysregulation of TH17 lymphocytes, and
the dysbiosis of established gut and other microbiota. The compelling notion
that a common antecedent pathological mechanism affects existing bone and
tissues with bone-forming potential (entheses), simultaneously with variable
effect in the former but bone-forming in the latter, drives basic research
forward and focuses our awareness on the effects on these bone mechanisms of the
increasing portfolio of targeted immunotherapies used in the clinic.

Abstract
Objectives To present the long-term (4-year) efficacy and safety of secukinumab in Taiwanese patients with active AS in the MEASURE 1 extension study. Methods This post hoc analysis reports data from Taiwanese patients originally randomized to subcutaneous secukinumab 150 or 75mg or placebo every 4 weeks (following intravenous loading dose) who were invited to enter the 3-year extension study. Assessments at Week 208 included ASAS20/40 responses and other clinically relevant endpoints. Efficacy data are presented as observed. Safety analyses included all patients who received ≥1 dose of secukinumab. Results Of the 57 Taiwanese patients in the core trial, 48 entered the extension study and 87.5% patients (42/48) completed 4 years of treatment. Thirteen Taiwanese patients (including placebo-switchers) were escalated from 75 to 150mg (approved dose) at some point starting from Week 172. ASAS20/40 responses were sustained through 4 years in the Taiwanese patients who were originally randomized to secukinumab 150mg. Clinical responses were improved in those patients who received dose-escalation from 75 to 150mg during the study. No unexpected safety signals were reported. Conclusion Secukinumab 150mg demonstrated sustained efficacy over 4 years in Taiwanese patients with active ankylosing spondylitis. The safety profile of secukinumab was consistent with previous reports. ClinicalTrialsgov identifier NCT01863732.

Abstract
Spondyloarthritis (SpA) are a heterogeneous group of inflammatory chronic diseases characterized by sharing common pathogenic, clinical and radiologic features. The aim of this review is to support clinicians in understanding and managing this complex disease, from pathogenesis to therapeutic targets, through a systematic review of the current literature in accordance with PRISMA guidelines and checklist. HLA-B27 has been found to be associated with axial involvement either in SA and in PsA patients: it might be involved through presentation of an "arthritogenic peptide" to autoreactive CD8+ T cells or might accumulate in misfolded form and induce production pro-inflammatory cytokines by binding to several innate immune receptors. This genetic background in combination with mechanical stress leads to the activation of both innate and acquired immune responses as well as a possible role of autoimmunity in SpA pathogenesis. The release of IL-23 and IL-17 is relevant for their systemic and local effect on bone, inducing the activation of osteoclasts. Thus, the regulatory role of IL-17 on fibroblasts, osteoblasts and chondrocytes has an impact in both synovial inflammation and joint destruction. Innovative therapies targeting IL-12/23 and IL-17 and the use of small targeted synthetic molecules, as JAK-inhibitors, proved to be effective in SpA patients representing an alternative strategy to TNF-inhibitors.

Abstract
Psoriasis is a chronic, immune-mediated, systemic, inflammatory disorder characterized by skin plaques and, often, nail disease and arthritis that contribute to reduced quality of life. Psoriatic arthritis-a heterogeneous, inflammatory, musculoskeletal disease that can cause permanent damage to both peripheral and axial joints-is the most common comorbidity of psoriasis. Axial disease occurs in 25% to 70% of patients with PsA, with some patients exclusively experiencing axial joint involvement. Early therapeutic intervention is important for preventing permanent joint and spine damage and loss of functionality in these patients. Because skin symptoms associated with psoriasis often precede psoriatic arthritis, dermatologists are uniquely positioned to play an important role in identifying and treating patients with psoriatic arthritis. Proactive screening of patients with all severities of psoriasis for the signs and symptoms of psoriatic arthritis is key to early diagnosis and intervention. In this review, we discuss the clinical presentation, risk factors, and treatment options for psoriatic arthritis with axial involvement, with the aim of helping dermatologists understand the disease and identify patients who might benefit from further assessment, treatment, and/or referral to a rheumatology practice.

Abstract
Secukinumab, ixekizumab and brodalumab are monoclonal antibody therapies that inhibit interleukin (IL)-17 activity and are widely used for the treatment of psoriasis, psoriatic arthritis and ankylosing spondylitis. The promising efficacy results in dermatology and rheumatology prompted the evaluation of these drugs in Crohn's disease and ulcerative colitis, but the onset of paradoxical events (disease exacerbation after treatment with a theoretically curative drug) prevented their approval in patients with inflammatory bowel diseases (IBDs). To date, the pathophysiological mechanisms underlying these paradoxical effects are not well defined, and there are no clear guidelines for the management of patients with disease flare or new IBD onset after anti-IL-17 drug therapy. In this review, we summarise the literature on putative mechanisms, the clinical digestive effects after therapy with IL-17 inhibitors and provide guidance for the management of these paradoxical effects in clinical practice.

THE LANCET. RHEUMATOLOGY 2020; 2:e339-e346. [PMID: 38273597 DOI: 10.1016/s2665-9913(20)30066-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 02/28/2020] [Accepted: 03/02/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Secukinumab, a fully human monoclonal antibody that directly inhibits interleukin 17A, has shown significant and sustained improvement in the signs and symptoms of ankylosing spondylitis over 3 years in the MEASURE 2 study. We report the 5-year (end-of-study) results of subcutaneous secukinumab 150 mg in the MEASURE 2 study. METHODS MEASURE 2 was a phase 3, double-blind, randomised, placebo-controlled, study done in 13 countries and 53 centres. Patients with ankylosing spondylitis who were 18 years of age or older and fulfilled the modified New York criteria were randomly assigned to receive secukinumab (150 mg or 75 mg) or placebo subcutaneously at baseline and weeks 1, 2, and 3, and then every 4 weeks from week 4. At week 16, patients initially given placebo were randomly assigned again (placebo switchers) to receive secukinumab 150 mg or 75 mg. Efficacy results are reported for patients initially randomised to secukinumab 150 mg and those who switched from placebo to secukinumab 150 mg at week 16. An optional dose escalation from secukinumab 75 mg to 150 mg was initiated beginning week 140. We assessed efficacy endpoints at week 260 (5 years), including Assessment of Spondyloarthritis International Society (ASAS) 20 and ASAS 40, inactive disease according to ankylosing spondylitis disease activity score with C-reactive protein (ASDAS-CRP), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), BASDAI50, Bath Ankylosing Spondylitis Metrology Index, Bath Ankylosing Spondylitis Functional Index, Short Form-36 Physical Component Summary, and ASAS partial remission. Analyses were stratified by anti-tumour necrosis factor (TNF) status (anti-TNF-naive and anti-TNF inadequate response). The safety analysis included all patients who received one dose or more of secukinumab. We report data as observed without accounting for missing data. The MEASURE 2 study was registered with ClinicalTrials.gov, NCT01649375. FINDINGS 219 patients were randomly assigned during the trial and 150 (68%) completed 5 years of treatment, including 82 (77%) of 106 patients in the secukinumab 150 mg group and 68 (65%) of 105 in the secukinumab 75 mg group. Efficacy analysis in the secukinumab 150 mg group included 53 patients who completed the study and one additional patient who was assessed in the treatment period weeks 212-260, but did not complete the study. 134 (61%) of 219 patients were anti-TNF-naive and 85 (39%) were anti-TNF inadequate responders. ASAS responses at 5 years with secukinumab 150 mg were 36 (67%) of 54 patients (ASA20) and 27 (50%) patients (ASAS40). Sustained improvement was observed across other efficacy endpoints with secukinumab 150 mg at 5 years. At 5 years, the proportion of patients achieving efficacy endpoints of BASDAI 50 response was 53% (44/83); ASAS 5/6 response was 51% (42/83); ASDAS-CRP inactive disease was 21% (17/81); and ASAS partial remission was 25% (21/83). Exposure-adjusted incidence rates with any secukinumab dose for selected adverse events were 1·0 per 100 patient-years (95% CI 0·4-1·9) for Candida infections, 0·5 (0·1-1·2) for Crohn's disease, 0·4 (0·1-1·1) for ulcerative colitis, 0·6 (0·2-1·4) for major adverse cardiovascular events, 0·5 (0·1-1·2) for uveitis, and 0·6 (0·2-1·4) for malignant or unspecified tumours. INTERPRETATION Secukinumab 150 mg provided sustained improvement in the signs, symptoms, and physical function in patients with ankylosing spondylitis after 5 years of treatment. The safety profile of secukinumab remained consistent with previous reports. FUNDING Novartis Pharma.

Effect of Therapy on Radiographic Progression in Axial Spondyloarthritis: A Systematic Review and Meta-Analysis. Arthritis Rheumatol 2020; 72:733-749.

Abstract
OBJECTIVE To investigate the effect of therapies on radiographic progression in patients with axial spondyloarthritis (SpA). METHODS A comprehensive database search for studies assessing radiographic progression in axial SpA (particular treatment versus no treatment of interest) was performed. Study-specific standardized mean differences in treatment outcomes at 2 and ≥4 years were estimated and combined using random-effects models. RESULTS Twenty-four studies in patients with axial SpA were identified, of which 18 involved tumor necrosis factor inhibitors (TNFi), 8 involved nonsteroidal antiinflammatory drugs (NSAIDs), and 1 involved secukinumab. Spinal radiographic progression, as measured by the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS), was not significantly different between TNFi-treated and biologics-naive patients at 2 years (mSASSS difference -0.73 [95% confidence interval (95% CI) -1.52, 0.12], I2 = 28%) and ≥4 years (mSASSS difference -2.03 [95% CI -4.63, 0.72], I2 = 63%). Sensitivity analyses restricted to studies with a low risk of bias showed a significant difference in spinal radiographic progression between TNFi-treated and biologics-naive patients at ≥4 years (mSASSS difference -2.17 [95% CI -4.19, -0.15]). No significant difference in spinal radiographic progression was observed between NSAID-treated and control patients (mSASSS difference -0.30 [95% CI -2.62, 1.31], I2 = 71%) or between secukinumab-treated and biologics-naive patients (mSASSS difference -0.34 [95% CI -0.85, 0.17]). With regard to treatment differences in patients with nonradiographic axial SpA or in patients with radiographic progression measured using the sacroiliac joint score, an insufficient number of studies were available for analysis. CONCLUSION Although no significant protective effect of TNFi treatment on spinal radiographic progression was seen over the course of 2 years or ≥4 years in patients with axial SpA, our analysis restricted to studies with a low risk of bias showed a protective effect of TNFi after ≥4 years. Therefore, long-term TNFi exposure might confer beneficial effects on spinal radiographic progression in axial SpA. No difference in radiographic progression at 2 years was seen in either the NSAID or secukinumab treatment groups compared to their controls. Future studies should explore the effects of biologic treatment on radiographic progression, as well as the effects of long-term biologics exposure, in patients with early axial SpA or those with nonradiographic axial SpA.

Abstract
Axial spondyloathritis (axSpA) treatment with biologic DMARDs was previously focused around anti-TNF agents. Significant advances in research have led to new therapeutic options, such as secukinumab, an IL-17 inhibitor, which has been approved for the treatment of axSpA. Two other biologic agents that are already licensed for rheumatoid and psoriatic arthritis, tofacitinib and ixekizumab, have demonstrated improved outcomes in axSpA. Several newer agents have been developed to inhibit IL-17, IL-23, and JAK. Early trials are promising; however, further research is needed. Rapid expansion of therapies available to treat axSpA could lead to improved disease control and decreased disease burden.

Abstract
Treat to target describes a management paradigm that involves choosing a clinically relevant target, assessment with validated measures at a prespecified frequency, and a change in therapy if the target is not met. Although guidelines recommend treating to target in axial spondyloarthritis (axSpA), ideal methods to reach this target remain controversial. This review focuses on background for a treat-to-target strategy in axSpA. Potential targets of treatment, association of targets with outcomes, evidence of treatment impact on outcomes, and how treat to target has been incorporated into treatment guidelines are discussed. Treat-to-target trials and the research agenda for studies in axSpA are discussed.

Abstract
Nonsteroidal antiinflammatory drugs (NSAIDs) are the first-line pharmacotherapy for patients with axial spondyloarthritis (SpA). In recent years, treatment options have expanded with the availability of biologic agents, including tumor necrosis factor inhibitors and interleukin-17 inhibitors. However, a treatment strategy that clearly prevents syndesmophyte formation has not been established. Observational studies of patients with ankylosing spondylitis indicated potential disease-modifying effects of NSAIDs, but two randomized trials came to different conclusions. More broadly, whether any of the currently available medications for axial SpA have an effect on spine radiographic progression, beyond symptom control, remains inconclusive. In this article, we will review clinical studies of the disease modification effects of NSAIDs and biologics in axial SpA; examine genetic, animal, and clinical evidence of the effects of NSAIDs on bone formation; and discuss how future studies may investigate the question of disease modification in axial SpA.

Abstract
We aimed to perform a structured literature review of spinal radiographic progression, as assessed by the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS), in patients with ankylosing spondylitis (AS) or nonradiographic axial spondyloarthritis (nr-axSpA) treated with biologic therapy. Searches were limited to English language manuscripts published in the 11 years prior to 9 July 2019. Randomized controlled trials, open-label extensions (OLEs) and observational studies reporting mSASSS progression in patients with AS or nr-axSpA treated with biologics were eligible for inclusion. Bias was assessed using the methodological index for nonrandomized studies (MINORS) tool. Among the 322 studies identified in the literature search, 23 (11 OLEs and 12 cohort studies) met the eligibility criteria and were selected for inclusion. Most studies reported mSASSS progression in patients with AS receiving tumor necrosis factor inhibitor (TNFi) treatment. One study reported mSASSS progression in patients with AS treated with secukinumab, an interleukin-17A inhibitor. The mean (range) MINORS score was 11.3 (7-15) for the 15 noncomparative studies and 15 (12-22) for the 8 comparative studies. Although results of the individual studies were variable, mSASSS progression in patients with AS was generally minimal and slow with long-term TNFi therapy. Moreover, odds ratios for the likelihood of mSASSS progression with/without TNFi favoured TNFi therapy in several of the cohort studies. The rate of mSASSS progression following continuous secukinumab treatment was low and remained stable over 4 years. Of two studies reporting progression in patients with nr-axSpA treated with TNFis, one showed no mSASSS progression; however, the lack of control limited comparative conclusions.

Abstract
Drug treatment in patients with axial spondylarthritis (axSpA) aims to modify symptoms and complaints and currently includes the substance groups of nonsteroidal anti-inflammatory drugs (NSAID) and biologicals (disease-modifying antirheumatic drugs, bDMARDS). Treatment with NSAIDs is the first line treatment according to international and national recommendations. Patients with persisting high disease activity despite continuous standard treatment with NSAIDs, should be treated with biologicals. In Germany treatment with tumor necosis factor (TNF) inhibitors or interleukin 17 inhibitor (secukinumab) are currently approved for treating patients with ankylosing spondylitis (AS). Treatment of patients with non-radiographic axSpA (nr-axSpA) is restricted to TNF inhibitors (except infliximab) in Germany. The efficacy and safety are documented for both substance groups; however, due to the longer time since approval longitudinal data for TNF inhibitors are more robust and the data contain information about switching within a substance group. Although overall retention rates of TNF inhibitors are similar despite the difference in formation of antidrug antibodies, data from cohorts provide information about long-term loss of efficacy, switching and also discontinuation strategies. In the meantime, various biosimilars have been approved for infliximab, etanercept and adalimumab. Conventional basic treatment (csDMARDs) and in particular intra-articular administration of glucocorticoids can only be prescribed for axSpA patients with peripheral arthritis.

Abstract
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.

Abstract
Spondyloarthritis is a group of chronic inflammatory systemic diseases characterized by axial and/or peripheral joints inflammation, as well as extra-articular manifestations. The classification axial spondyloarthritis is adopted when the spine and/or the sacroiliac joints are predominantly involved. This version of recommendations replaces the previous guidelines published in May 2013.A systematic literature review was performed, and two hundred thirty-seven studies were selected and used to formulate 29 recommendations answering 15 clinical questions, which were divided into four sections: diagnosis, non-pharmacological therapy, conventional drug therapy and biological therapy. For each recommendation the level of evidence supporting (highest available), the strength grade according to Oxford, and the degree of expert agreement (inter-rater reliability) is informed.These guidelines bring evidence-based information on clinical management of axial SpA patients, including, diagnosis, treatment, and prognosis.

Abstract
Objective The aim was to investigate the relationship between the intensity of spinal inflammation using the apparent diffusion coefficient (ADC) and radiographic progression in axial SpA. Methods This is a cross-sectional study of participants with axial SpA and back pain. Clinical, biochemical and radiological parameters were collected. The ankylosing spondylitis disease activity score (ASDAS)-CRP was determined. Radiographic progression was represented by the modified Stoke ankylosing spondylitis spine score (mSASSS). MRI with short tau inversion recovery (STIR) and diffusion-weighted imaging sequences were performed simultaneously. Inflammatory lesions on STIR were used for the Spondyloarthritis Research Consortium of Canada (SPARCC) MRI indexes and as references in outlining regions of interest in ADC maps to produce mean (ADCmean) and maximal (ADCmax) ADC values. Univariate and multivariate linear regression analyses were used to determine independent associations between ADC and radiographic progression. Results The 84 participants with identifiable lesions on spinal ADC maps recruited were characterized by a mean (s.d.) age of 45.01 (13.68) years, long disease duration [13.40 (11.01) years] and moderate clinical disease activity [ASDAS-CRP 2.07 (0.83)]. Multivariate regression analysis using ADCmean as the independent variable showed that age (regression coefficient [B] = 0.34; P = 0.01), male sex (B = 0.25; P = 0.04) and ADCmean (B = 0.30; P = 0.01) were positively associated with mSASSS. Multivariate regression analysis using ADCmax as the independent variable showed a tendency for ADCmax to be associated with mSASSS (B = 0.21; P = 0.07). Conclusion The intensity of spinal inflammation as determined by ADC is associated with radiographic progression in participants with active axial SpA.

Abstract
To summarize, the currently available imaging procedures have various possibilities to visualize or sometimes to predict the osteogenesis pathognomonic for axial spondylarthritis (axSpA). The individual imaging techniques of X‑rays, computed tomography (CT) and magnetic resonance imaging (MRI) all have strengths and weaknesses in the diagnostics of axSpA. The generally easily available X‑ray imaging rapidly provides information on the condition of large sections of the skeleton. In particular, it can depict the chronic stages with various structural alterations of the sacroiliac joint and syndesmophytes and ankylosis of the spine. The CT technique, which principally has the same contrast as X‑rays, also shows pathological ossifications but without superimpositions, with better resolution of details and a higher dimensionality. The MRI technique has a superior soft tissue contrast so that acute inflammatory stages, such as bone marrow edema and erosion of the edges of vertebrae of the spine (shiny corners, Romanus lesions) or erosions and bone marrow edema of the sacroiliac joint are easily visible. Bony reconstruction processes can be visualized better in X‑ray imaging and particularly in CT, which increases the evidential value of X‑ray, CT and MRI techniques. The positions of conventional radiography and MRI are well-established in the diagnostic algorithm; however, low-dose CT of the spine is still in the experimental stage but the initial results look promising.

Abstract
Secukinumab (Cosentyx®), a first-in-class fully human monoclonal antibody against interleukin-17A, is approved in several countries, including the USA and those of the EU, for the treatment of ankylosing spondylitis (AS). Subcutaneous secukinumab significantly improved the clinical signs and symptoms of AS versus placebo in three of four phase III trials. The benefits of secukinumab were generally seen regardless of whether patients had or had not received previous tumour necrosis factor (TNF) inhibitor therapy, and were sustained during longer-term (up to 5 years) treatment. Secukinumab was also associated with improvements in spinal mobility, physical function, health-related quality of life and work productivity in some of the trials. In MEASURE 1, secukinumab reduced inflammation in the sacroiliac joint, and slowed radiographic progression. Secukinumab was generally well tolerated during up to 5 years’ treatment; the most commonly reported adverse event was nasopharyngitis. In the minority of patients who developed anti-drug antibodies (ADAs), ADAs did not decrease efficacy or increase adverse events. In conclusion, secukinumab is an effective therapy for TNF inhibitor-naive patients with active AS, and provides a useful treatment option for patients who have an inadequate response to or are intolerant of TNF inhibitors.

Abstract
The cytokines IL-23 and IL-17 have an important role in the pathogenesis of, and as a therapeutic target in, both animal models of chronic inflammation and some human chronic inflammatory diseases. The traditional view is that a main source of IL-17 is T cells and that IL-17 production is under the control of IL-23. IL-17 inhibition has shown good efficacy in clinical trials for ankylosing spondylitis (AS), a subtype of axial spondyloarthritis (axSpA) characterized by radiographic evidence of sacroiliitis. On the basis of data from animal models, genetic studies and the investigation of tissue and blood samples from patients with AS, IL-23 had also been predicted to be important in the pathogenesis of this disease and was therefore considered a potential therapeutic target for axSpA. However, two placebo-controlled, double-blind clinical trials in axSpA of monoclonal antibodies directed against either the p40 protein or the p19 protein of the IL-23 molecule had clear negative results. These findings indicate that IL-23 and IL-17 are at least partly uncoupled in axSpA. Reasons as to why, when and how such an uncoupling might occur are discussed in this Review, with special reference to the unique microenvironment of the subchondral bone marrow in axSpA.

Abstract
Although the pathogenesis of spondylarthritis (SpA) has been the subject of intensive research in recent years, the consequences for treatment are relatively minor. Basic research studies indicated a potentially important role of the cytokines tumor necrosis factor (TNF) alpha and interleukin (IL)-17 for the pathogenesis of SpA but their outstanding role could then only be demonstrated by their inhibition in clinical studies, while other promising targets, such as IL‑23 and IL‑6 could not be shown to be relevant (at least against axial manifestations) in clinical studies. The intestinal microbiota probably plays an important role in the pathogenesis but not yet for the treatment of SpA. Ultimately, early effective and long-term suppression of inflammation is currently the best method to prevent ankylosis in the long run.

Abstract
Objective This study aimed to report end-of-study results on efficacy and safety of secukinumab 150 mg through 5 years in patients with ankylosing spondylitis (AS; MEASURE 1 extension trial (NCT01863732)). Methods After the 2-year core trial, 274 patients receiving subcutaneous secukinumab 150 or 75 mg (following intravenous loading or initial placebo treatment to 16/24 weeks) every 4 weeks were invited to enter the 3-year extension study. Dose escalation from 75 to 150 mg (approved dose) was allowed at or after week 156 based on the judgement of the treating physician. Assessments at week 260 (5 years) included Assessment of SpondyloArthritis international Society (ASAS) 20/40 and other efficacy outcomes. Data are presented as observed. Safety assessment included all patients who received ≥1 dose of study treatment. Results Of the 274 patients who entered the extension study, 84% (230/274) completed 5 years of treatment. ASAS20/40 responses were 78.6/65.2%, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) 50 response was 63.4% and mean (±SD) BASDAI total score was 2.6±1.76 with secukinumab 150 mg at 5 years. Improvements in efficacy outcomes were sustained through 5 years. A total of 82 patients on secukinumab 75 mg (56.2%) had their dose escalated to 150 mg after week 168; ASAS40, ASAS-PR, ASAS 5/6 and BASDAI50 responses were improved in patients whose dose was escalated from secukinumab 75 to 150 mg. Secukinumab was well tolerated with a safety profile consistent over the course of the study. Conclusions Secukinumab 150 mg provided sustained efficacy across multiple domains of AS with a favourable and consistent safety profile through 5-year treatment. Over 50% of patients required dose escalation from 75 to 150 mg and efficacy improved in these patients.

Abstract
PURPOSE OF REVIEW There was a substantial progress in the field of spondyloarthritis (SpA) in terms of understanding disease mechanisms, early diagnosis, and improved treatment. Nonetheless, several unresolved questions and unmet needs do remain. RECENT FINDINGS Although the diagnostic delay in axial SpA is decreasing, it remains one of the longest in rheumatology. Application of referral strategies, as well as correct application and interpretation of imaging finding in the clinical context, is the main key to early diagnosis of axial SpA. Tumor necrosis factor (TNF) alpha and interleukin (IL)-17 represent currently two major treatment targets in SpA, while other promising targets such as IL-23 or IL-6 failed in clinical trials. There is an unmet need for strategy trials to optimize and to individualize treatment in SpA. The role of Janus kinases and their blockade in SpA is still to be explored. TNF blockade showed efficacy in peripheral SpA, and other targets (IL-17 and IL-23) should be investigated in clinical trials. Early, effective, and long-term suppression of inflammation is currently the best method to prevent structural damage progression in the spine in axial SpA, while specific effects of IL-17 blockade and of nonsteroidal anti-inflammatory drugs on new bone formation are still being investigated. This review summarizes the recent advances in diagnosis and treatment of SpA and discusses the current unmet needs in the field.

Abstract
OBJECTIVE The aim of this study was to compare radiographic progression in patients with ankylosing spondylitis (AS) treated for up to 2 years with secukinumab (MEASURE 1) with a historical cohort of biologic-naïve patients treated with NSAIDs (ENRADAS). METHODS Baseline and 2-year lateral cervical and lumbar spine radiographs were independently evaluated using mSASSS by two readers, who were blinded to the chronology and cohort of the radiographs. The primary endpoint was the proportion of patients with no radiographic progression (mSASSS change ≤ 0 from baseline to year 2). The Primary Analysis Set included patients with baseline (≤ day 30) and post-baseline day 31-743 radiographs. Sensitivity analyses were performed to assess the robustness of the comparison between the two cohorts, as follows: Sensitivity Analysis Set 1 included all patients with baseline (≤ day 30) and year 2 (days 640-819) radiographs; Sensitivity Analysis Set 2 included all patients with baseline and post-baseline (> day 30) radiographs. RESULTS A total of 168 patients (84%) from the MEASURE 1 cohort and 69 (57%) from the ENRADAS cohort qualified for the Primary Analysis Set. Over 2 years, the LS (SE) mean change from baseline in mSASSS for the primary analysis was 0.55 (0.139) for MEASURE 1 vs 0.89 (0.216) for ENRADAS (p = 0.1852). Mean changes from baseline in mSASSS were lower in MEASURE 1 vs ENRADAS for the primary and sensitivity analyses. The proportion of patients with no radiographic progression was consistently higher in the MEASURE 1 vs ENRADAS cohort across all cutoffs for no radiographic progression (change in mSASSS from baseline to year 2 of ≤ 0, ≤ 0.5, ≤ 1, and ≤ 2), but the differences were not statistically significant. CONCLUSION Secukinumab-treated patients demonstrated a numerical, but statistically non-significant, higher proportion of non-progressors and lower change in mSASSS over 2 years versus a cohort of biologic-naïve patients treated with NSAIDs.

Abstract
INTRODUCTION Interleukin (IL)-17 is a proinflammatory cytokine considered to play a significant role in the immunopathogenesis of ankylosing spondylitis (AS)/axial spondyloarthritis (axSpA) as well as of other spondyloarthritides. There is a number of substances targeting IL-17, which are at different stages of development in the axSpA indication. AREAS COVERED This review summarizes the current evidence on the role of IL-17 in the pathophysiology of axSpA and provided a comprehensive review of clinical and radiographic outcomes as well as of safety data from studies with IL-17A inhibitors secukinumab and ixekizumab. Ongoing studies on other IL-17 inhibitors (bimekizumab, brodalumab and BCD-085) that are being developed are also summarized. EXPERT OPINION The development of the IL-17 inhibitors has expanded AS treatment with effective options and confirmed the pathophysiological role of IL-17 in axSpA. IL-17 inhibition showed sufficient efficacy against signs and symptoms of the disease even after the failure of tumor necrosis factor inhibitors, being at the same time reasonably safe.
