Introduction: Patients with psoriatic arthritis (PsA) require treatment providing durable long-term efficacy in different disease domains as well as safety. We present 100-week efficacy and safety results of risankizumab in patients with active PsA and previous inadequate response/intolerance to ≥ 1 conventional synthetic disease-modifying antirheumatic drug (csDMARD-IR). Methods: KEEPsAKE 1 (NCT03675308) is a global phase 3 study, including a 24-week, double-blind, placebo-controlled and ongoing open-label extension periods. Patients were randomized 1:1 to receive risankizumab 150 mg or placebo at baseline and weeks 4 and 16. After week 24, all patients received open-label risankizumab every 12 weeks thereafter. Patients were evaluated through 100 weeks. Endpoints included achieving ≥ 20% reduction in American College of Rheumatology criteria for symptoms of rheumatoid arthritis (ACR20), minimal disease activity (MDA; defined as ≥ 5/7 criteria of low disease activity and extent), and other measures. Results: Overall, 828/964 (85.9%) patients completed week 100. For patients receiving continuous risankizumab, 57.3%, 70.6%, and 64.3% achieved ACR20 at weeks 24, 52, and 100, respectively. For the placebo/risankizumab cohort, 33.5% achieved ACR20 at week 24 but increased after switching to active treatment at weeks 52 (63.7%) and 100 (62.1%). In ACR20 responders at week 52, 81.2% of both treatment cohorts maintained response at week 100. MDA was achieved by 25.0%, 38.3%, and 38.2% of the continuous risankizumab cohort at weeks 24, 52, and 100. In the placebo/risankizumab cohort, 10.2% achieved MDA at week 24, increasing at weeks 52 (28.0%) and 100 (35.2%). MDA response was maintained at week 100 in week 52 responders in the continuous risankizumab (75.5%) and placebo/risankizumab cohorts (78.2%). Similar trends were observed for other efficacy measures. Risankizumab was generally well tolerated through 100 weeks. Conclusions: For patients with active PsA who are csDMARD-IR, risankizumab demonstrated durable long-term efficacy and was generally well tolerated, with a consistent long-term safety profile. Trial Registration: ClinicalTrials.gov identifier, NCT03675308. Plain Language Summary: Psoriatic arthritis (PsA) often affects individuals with the skin condition psoriasis. A biologic disease-modifying antirheumatic drug can help control inflammation and regulate the immune system to ease symptoms and slow progression of PsA. The ongoing KEEPsAKE 1 study is evaluating the efficacy and safety of risankizumab in patients with active PsA who previously have not had success with ≥ 1 conventional disease-modifying antirheumatic drug. Patients were initially treated with risankizumab 150 mg (continuous risankizumab group) or inactive drug (inactive drug/risankizumab group). After 24 weeks, all received risankizumab for the rest of the study. At week 100, 64% (continuous risankizumab group) and 62% (inactive drug/risankizumab group) of patients had ≥ 20% improvement in PsA symptoms (measured using American College of Rheumatology [ACR20] criteria). Both groups showed similar percentages at week 52 and improvement from week 24. In patients who achieved ACR20 at week 52, 81% maintained their ACR20 response at week 100. Minimal disease activity was defined as a combination of joint and skin symptoms, affected body surface area, pain, and physical functioning. At week 100, 38% of the continuous risankizumab group and 35% of the inactive drug/risankizumab group achieved minimal disease activity. Percentages were similar at week 52 and higher than week 24 in both groups. In patients who achieved minimal disease activity at week 52, 81% maintained response at week 100. All other measures of treatment responses showed similar patterns from the start of risankizumab through week 100. Risankizumab was considered generally safe by the treating physicians.

Introduction: For chronic diseases such as axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), and plaque psoriasis (PsO), treatment goals include remission or at least low disease activity (LDA) by 12 weeks. Improvements in symptoms such as pain and fatigue should also be treatment goals. Methods: ADEQUATE was a German, prospective, non-interventional study to evaluate the proportion of patients with rheumatoid arthritis, PsA, axSpA, or PsO who, in routine clinical practice, benefit from the continuation of treatment with etanercept (ETN) beyond 12 weeks, even when their treatment goals have not yet been reached. Patient-reported outcomes (PROs) and changes in concomitant glucocorticoid use were also recorded. This article focuses on results for patients with axSpA and PsA; data for patients with PsO are described briefly. Results: In total, 305, 254, and 70 patients with axSpA, PsA, and PsO, respectively, were included. Rates of remission at week 12 and week 24, respectively, were 19% and 18% for axSpA, 38% and 51% for PsA, and 7% and 19% for PsO. Rates of LDA at week 12 and week 24, respectively, were 39% and 45% for axSpA, 50% and 60% for PsA, and 34% and 51% for PsO. Extending treatment up to 52 weeks was associated with stable rates of or further increases in remission and LDA rates. Improvements in pain, fatigue, and depression (axSpA, PsA, and PsO) and reductions in concomitant glucocorticoid use (axSpA and PsA) were observed. No new safety signals were detected. Conclusion: These findings confirm the effectiveness and safety of ETN in routine clinical practice for several indications and highlight potential benefits of continuing ETN treatment in patients who have not reached their treatment goals after 12 weeks. Additional benefits included improvements in PROs and reduction of concomitant glucocorticoids. Trial Registration: ClinicalTrials.gov NCT02486302. Plain Language Summary: Axial spondyloarthritis is a disorder that causes joint pain mainly in the spine and can cause deformation of the spine. Psoriatic arthritis and plaque psoriasis are disorders that cause dry, itchy, and raised skin patches. Psoriatic arthritis also causes swollen, stiff, and painful joints. Etanercept is a treatment used to reduce the symptoms of axial spondyloarthritis, psoriatic arthritis, and plaque psoriasis. The aim of treatment is remission, or low disease activity after 12 weeks. In this study, people received etanercept for up to 52 weeks from their usual doctors in Germany. A total of 305 people with axial spondyloarthritis, 254 people with psoriatic arthritis, and 70 people with plaque psoriasis took part in the study. After 12 weeks of treatment, 19 in 100 people with axial spondyloarthritis were in remission and 39 in 100 people had low disease activity. In addition, 38 in 100 people with psoriatic arthritis were in remission and 50 in 100 people had low disease activity. Finally, 7 in 100 people with plaque psoriasis were in remission and 34 in 100 people had low disease activity. These numbers remained mostly stable until the end of the study. People also reported less pain, fatigue, and depression. Most people were able to use less glucocorticoids. The number and types of unwanted side effects were similar to those seen in other studies of etanercept in people with axial spondyloarthritis, psoriatic arthritis, or plaque psoriasis.

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

Psoriatic arthritis (PsA) is a chronic inflammatory systemic disease whose activity is often assessed using the Disease Activity Score 28 (DAS28-CRP). The present study was designed to investigate the significance of individual components within the score for PsA activity. A cohort of 80 PsA patients (44 women and 36 men, aged 56.3 ± 12 years) with a range of disease activity from remission to moderate was analyzed using unsupervised and supervised methods applied to the DAS28-CRP components. Machine learning-based permutation importance identified tenderness in the metacarpophalangeal joint of the right index finger as the most informative item of the DAS28-CRP for PsA activity staging. This symptom alone allowed a machine learned (random forests) classifier to identify PsA remission with 67% balanced accuracy in new cases. Projection of the DAS28-CRP data onto an emergent self-organizing map of artificial neurons identified outliers, which following augmentation of group sizes by emergent self-organizing maps based generative artificial intelligence (AI) could be defined as subgroups particularly characterized by either tenderness or swelling of specific joints. AI-assisted re-evaluation of the DAS28-CRP for PsA has narrowed the score items to a most relevant symptom, and generative AI has been useful for identifying and characterizing small subgroups of patients whose symptom patterns differ from the majority. These findings represent an important step toward precision medicine that can address outliers. [ABSTRACT FROM AUTHOR]

Objective We investigated the impact of concomitant MTX on ustekinumab (UST) levels and antidrug antibody (ADA) formation in PsA and evaluated consequences in pharmacodynamics and pharmacokinetics. Methods We conducted a post-hoc analysis on 112 PsA serum samples of subjects treated with open-label UST and either concomitant MTX (UST/MTX, n  = 58) or placebo (UST/pbo, n  = 54) obtained in a randomized (1:1), double-blind, multicentre trial. A validated antibody-binding-based multitiered testing was used to detect ADA and ADA with neutralizing capacity (nADA). The impact of MTX on UST immunogenicity was analysed by comparison of UST/pbo with UST/MTX cohorts at different time points. Patient- and disease-related predispositions for ADA formation were investigated with multiple linear regression analysis. Immunogenicity impact on pharmacokinetics, safety and efficacy was determined by cohort comparison between patients with and without ADA formation. Results Over 52 weeks, 11 UST/pbo- and 19 UST/MTX-treated patients developed ADA (P  > 0.05). In the UST/pbo cohort, the visit-dependent UST levels were in the range of 0.047 (0.05) –0.110 (0.07) µg/ml overall, and 0.037 (0.04)–0.091 (0.08) µg/ml in ADA-confirmed subjects. In UST/MTX-treated patients, the UST levels exhibited an intervisit variation in the range of 0.0502 (0.04)–0.106 (0.07) µg/ml overall and 0.029 (0.03)–0.097 (0.07) µg/ml in ADA positive subjects (P  > 0.05). At week 52, ADA-confirmed patients did not differ significantly (P  > 0.05) in safety or clinical outcomes from ADA-negative patients. Conclusion Concomitant MTX had no significant impact on UST immunogenicity. Furthermore, ADA formation was not associated with impairments in UST safety, efficacy or trough levels.

Nail psoriasis is a difficult-to-treat manifestation of psoriatic disease affecting up to 80% of patients with psoriatic arthritis (PsA) and 40–60% of patients with plaque psoriasis (PsO). Ixekizumab (IXE), a high-affinity monoclonal antibody that selectively targets interleukin-17A, is approved for the treatment of patients with PsA and patients with moderate-to-severe PsO. This narrative review aims to summarize nail psoriasis data generated from IXE clinical trials in patients with PsA (SPIRIT-P1, SPIRIT-P2, and SPIRIT-H2H) and/or moderate-to-severe PsO (UNCOVER-1, -2, -3, IXORA-R, IXORA-S, and IXORA-PEDS) with an emphasis on head-to-head clinical trial data. Across numerous trials explored, IXE treatment was associated with greater improvement in resolution of nail disease versus comparators at week 24, results which were maintained up to and beyond week 52. Additionally, patients experienced higher rates of resolution of nail disease versus comparators at week 24 and maintained high levels of resolution up to week 52 and beyond. In both PsA and PsO, IXE demonstrated efficacy in treating nail psoriasis, and therefore may be an effective therapy option.

Summary: Background and objective: Psoriatic arthritis (PsA) is a chronic systemic inflammatory disease affecting the musculoskeletal system, skin and nails. The aim is to characterize sociodemographic and clinical patient profiles documented in dermatologic and rheumatologic care. Patients and Methods: Data of 704 patients with PsA from the dermatological Psoriasis Registry PsoBest (PB) and 1066 patients from the rheumatological disease registry RABBIT‐SpA (RS) were analyzed. Comparable anamnestic and clinical variables were identified and descriptively analyzed. Results: The mean age was 51.7 years in PB and 51.9 in RS. Disease duration of psoriasis was longer, mean cutaneous severity was higher in PB. However, more patients in RS vs. PB had tender joints and swollen joints. Mean Dermatology Life Quality Index was higher in PB and mean Health Assessment Questionnaire in RS. Patient reported global disease activity and pain were lower in PB. IL‐23 inhibitors were used more frequently in PB, and TNF inhibitors in RS. Conclusions: Clinical specialization was associated with different clinical and treatment patterns of PsA. This may indicate a selection by dominant manifestation of psoriatic disease and potentially by effects of health care access. Psoriatic arthritis should be treated in a multidisciplinary approach considering all facets of this complex disease. [ABSTRACT FROM AUTHOR]

Achieving a good outcome for a person with Psoriatic Arthritis (PsA) is made difficult by late diagnosis, heterogenous clinical disease expression and in many cases, failure to adequately suppress inflammatory disease features. Single-centre studies have certainly contributed to our understanding of disease pathogenesis, but to adequately address the major areas of unmet need, multi-partner, collaborative research programmes are now required. HIPPOCRATES is a 5-year, Innovative Medicines Initiative (IMI) programme which includes 17 European academic centres experienced in PsA research, 5 pharmaceutical industry partners, 3 small-/medium-sized industry partners and 2 patient-representative organizations. In this review, the ambitious programme of work to be undertaken by HIPPOCRATES is outlined and common approaches and challenges are identified. It is expected that, when completed, the results will ultimately allow for changes in the approaches to diagnosing, managing and treating PsA allowing for better short-term and long-term outcomes. Plain language summary: Improving outcomes in Psoriatic Arthritis Psoriatic Arthritis (PsA) is a form of arthritis which is found in approximately 30% of people who have the skin condition, Psoriasis. Frequently debilitating and progressive, achieving a good outcome for a person with PsA is made difficult by late diagnosis, disease clinical features and in many cases, failure to adequately control features of inflammation. Research studies from individual centres have certainly contributed to our understanding of why people develop PsA but to adequately address the major areas of unmet need, multi-centre, collaborative research programmes are now required. HIPPOCRATES is a 5-year, Innovative Medicines Initiative (IMI) programme which includes 17 European academic centres experienced in PsA research, 5 pharmaceutical industry partners, 3 small-/medium-sized industry partners and 2 patient representative organisations (see appendix). In this review, the ambitious programme of work to be undertaken by HIPPOCRATES is outlined and common approaches and challenges are identified. The participation of patient research partners in all stages of the work of HIPPOCRATES is highlighted. It is expected that, when completed, the results will ultimately allow for changes in the approaches to diagnosing, managing and treating PsA allowing for improvements in short-term and long-term outcomes.

Objective PsA is a chronic disease with heterogeneous clinical manifestations requiring treatment options with long-term efficacy and safety. In this follow-up analysis, the 52-week efficacy and safety of risankizumab 150 mg in patients with active PsA who had previous inadequate response/intolerance to one or more conventional synthetic DMARDs (csDMARD-IR) were evaluated. Methods KEEPsAKE 1 is an ongoing, global, phase 3 study with a 24-week, double-blind, placebo-controlled period (period 1) and an open-label extension period (period 2). In period 1, eligible patients were randomized 1:1 to receive subcutaneous risankizumab 150 mg or placebo at weeks 0, 4 and 16. At week 24 (period 2), all continuing patients received open-label risankizumab 150 mg every 12 weeks through week 208. Results At week 24, 57.3% of risankizumab-treated patients (n  =   483) achieved ≥20% improvement in ACR criteria (ACR20) vs 33.5% of placebo-treated patients (n  =   481; P  < 0.001). At week 52, 70.0% of patients who were randomized to receive continuous risankizumab therapy and 63.0% of patients who were randomized to receive placebo in period 1 and then receive risankizumab at week 24 achieved ACR20. Similar result trends were observed for other efficacy measures. Risankizumab was well tolerated through 52 weeks of treatment with a consistent safety profile from week 24 through week 52. Conclusion In patients with active PsA who were csDMARD-IR, continuous risankizumab treatment demonstrated robust long-term efficacy and was well tolerated through 52 weeks of treatment.

Introduction: Randomised clinical studies in psoriatic arthritis (PsA) do not always reflect patients in routine clinical practice. Large-scale data from routine practice are needed to better understand drug persistence, effectiveness and long-term safety of therapeutic agents. Methods: PsABIOnd is an international, prospective, observational study designed to collect long-term routine care data in patients with PsA who receive guselkumab (an interleukin-23 [IL-23] inhibitor) or an interleukin-17 (IL-17) inhibitor. Adult patients (≥ 18 years) with a confirmed diagnosis of PsA who are starting guselkumab or any approved IL-17 inhibitor as a first, second, third or fourth line of PsA treatment and who provide written informed consent will be eligible to participate. Participants will be followed for a maximum of 36 months (+3 months) from the start of treatment. Study visits will occur in line with the standard of care, approximately every 6 months, plus an additional visit at 3 months after the start of treatment. eDaily by PsABIOnd - aneHealth substudy, will document the impact of these treatments on wellbeing and symptoms in a subgroup of participants over a 24-week (+4 weeks) observation period on treatment. Planned Outcomes: The primary objective of PsABIOnd is to evaluate treatment persistence with guselkumab and IL-17 inhibitors. Data sources will include validated electronic patient-reported outcomes (ePROs) and physician-completed assessments. Safety data will be collected through reporting adverse events. The eDaily by PsABIOnd substudy will use wearable and digital technologies for continuous activity and sleep monitoring, and frequent patient eDiary and ePRO collection to provide a more detailed and comprehensive picture of PsA. Trial Registration: ClinicalTrials.gov identifier: NCT05049798. Plain Language Summary: Psoriatic arthritis (PsA) is a type of arthritis associated with inflammation that occurs in almost one-third of patients with the inflammatory skin condition psoriasis. PsA can vary between individuals, and typically causes joint pain, swelling and stiffness, affecting both physical and social well-being. Over the past decade, several new PsA treatments have become available. However, there is currently a lack of agreement about the best treatment options. As PsA is a chronic (long-term) disease, the duration of time a patient continues taking a prescribed treatment (termed "treatment persistence") is important. The randomised clinical trials used to determine if a treatment works use strict rules to select patients. Therefore, large studies from everyday practice are needed to better understand the effectiveness and safety of these PsA treatments for a wider range of patients. PsABIOnd is a real-life study that will compare guselkumab (an interleukin-23 inhibitor) and interleukin-17 inhibitors, which are two relatively new types of PsA treatments. The study will provide information about how long patients remain on these treatments and how effectively and safely they work over a 3-year period. PsABIOnd will also explore the impact of PsA on participants' lives by collecting information about their quality of life, disease activity and treatment satisfaction. In addition, participants also taking part in the eDaily by PsABIOnd substudy will wear a watch-like device and use a smartphone-based app to record measurements including activity, sleep, pain and well-being to give a detailed picture of PsA and its impact on patients' daily lives.

Objectives PsA is a heterogeneous disease that impacts many aspects of social and mental life, including quality of life. Risankizumab, an antagonist specific for IL-23, is currently under investigation for the treatment of adults with active PsA. This study evaluated the impact of risankizumab vs placebo on health-related quality of life (HRQoL) and other patient-reported outcomes (PROs) among patients with active PsA and inadequate response or intolerance to conventional synthetic DMARD (csDMARD-IR) in the KEEPsAKE 1 trial. Methods Adult patients with active PsA (n  = 964) were randomized (1:1) to receive risankizumab 150 mg or placebo. PROs assessed included the 36-Item Short-Form Health Survey (SF-36, v2), Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT-Fatigue), EuroQoL-5 Dimension-5 Level (EQ-5D-5L), Patient's Assessment of Pain, Patient's Global Assessment (PtGA) of Disease Activity, and Work Productivity and Activity Impairment–PsA (WPAI-PsA) questionnaire. Least squares (LS) mean change from baseline at week 24 was compared between risankizumab and placebo. Results At week 24, differences between groups were observed using LS mean changes from baseline in SF-36 physical component summary and mental component summary; FACIT-Fatigue; EQ-5D-5L; Patient's Assessment of Pain; PtGA; all eight SF-36 domains (all nominal P  < 0.001); and the WPAI-PsA domains of impairment while working (presenteeism), overall work impairment and activity impairment (all nominal P  < 0.01). Conclusion Risankizumab treatment resulted in greater improvements in HRQoL, fatigue, pain and work productivity in patients with active PsA who have csDMARD-IR, when compared with placebo.

Background: The optimal dose of rituximab in combination with leflunomide in patients with rheumatoid arthritis (RA) is not known. Methods: In Part 1 (previously reported) of the investigator-initiated AMARA study (EudraCT 2009-015950-39; ClinicalTrials.gov NCT01244958), improvements at week (W)24 were observed in patients randomized to rituximab + leflunomide compared with placebo + leflunomide. In the study reported here (Part 2), Part 1 responders received rituximab 500 or 1000 mg at W24/26 plus ongoing leflunomide. Patients were randomized at baseline to their eventual W24 treatment group. The Part 2 primary outcome was the mean Disease Activity Score-28 joints (DAS28) at W52, based on the last observation carried forward (LOCF) analyses and a two-sided analysis of variance. Patient-reported outcomes (PROs) and adverse events were evaluated. Results: Eighty-three patients received rituximab at W24/26 (31 rituximab→rituximab 1000 mg; 29 rituximab→rituximab 500 mg; 10 placebo→rituximab 1000 mg; 13 placebo→rituximab 500 mg). At W52, there were no significant differences in DAS28 between rituximab doses in patients originally treated with rituximab or those originally treated with placebo. In the Part 1 placebo group, the higher rituximab dose was associated with greater improvements in ACR response rates and some PROs. Adverse events were similar regardless of rituximab dose. Conclusions: Retreatment with rituximab 500 mg and 1000 mg showed comparable efficacy, whereas an initial dose of rituximab 500 mg was associated with lower response rates versus 1000 mg. Reduced treatment response with the lower dose in patients initially treated with placebo may have been influenced by small numbers and baseline disease activity. [ABSTRACT FROM AUTHOR]

Introduction: Psoriatic arthritis (PsA) is a chronic, progressive disease that places a significant burden on patients and healthcare systems. The SUSTAIN study collected real-world evidence on long-term effectiveness, impact on quality of life, and safety of ustekinumab treatment for PsA. Methods: SUSTAIN was a prospective, non-interventional study conducted in Germany. Patients with active PsA received ustekinumab for 160 weeks in routine clinical care, with assessments at baseline, week 4, and every 12 weeks thereafter. This analysis focuses on patients who remained in SUSTAIN until week 160. Results: Of 337 patients enrolled, 129 were documented at week 160, of which 123 (95.3%) had received previous PsA medication, including biologics. Decreases from baseline to week 4 were observed for tender joint count (TJC, 8.0 to 5.8) and swollen joint count (SJC, 4.5 to 3.1); these decreases continued to week 28 and were maintained to week 160 (1.0 and 0.4, respectively). Similarly, skin assessments in patients with PsA and psoriasis revealed improvement at week 4, which continued to week 28, with a sustained effect until week 160. Similar patterns of response were observed for patient-assessed pain, sleep quality, and health scores. Improvements in TJC, SJC, Psoriasis Area and Severity Index, and affected body surface area were observed irrespective of the number of prior biologic therapies used. Minimal disease activity was achieved by 36 (31.9%) patients at week 28, and by 38 (33.6%) at week 52. Ustekinumab-related adverse events (AEs) and serious AEs were reported in 61 (47.3%) and 4 (3.1%) patients, respectively. At week 160, 100% of patients assessed ustekinumab tolerability as good or very good. Conclusions: In a real-world setting, patients with active PsA who received ustekinumab until 160 weeks (3 years), including those who received prior biologic therapies, had a rapid onset of effect and sustained response to treatment, with high tolerability. Trial registration: PEI NIS No. 290. [ABSTRACT FROM AUTHOR]

Introduction: The objective of this work was to assess the efficacy and safety of risankizumab in psoriatic arthritis (PsA) over 76 weeks. Methods: In this double-blind, dose-ranging phase 2 study, adults with active PsA were randomized 2:2:2:1:2 to risankizumab 150 mg at weeks 0, 4, 8, 12, and 16 (arm 1), 150 mg at weeks 0, 4, and 16 (arm 2), 150 mg at weeks 0 and 12 (arm 3), 75 mg at week 0 (arm 4), or placebo (arm 5). Patients completing week 24 could receive risankizumab 150 mg in a 52-week open-label extension study. Efficacy assessments included American College of Rheumatology (ACR) responses, Psoriasis Area Severity Index (PASI) responses, minimal disease activity (MDA), and 28-joint Disease Activity Score based on C-reactive protein (DAS28[CRP]). Results: Of 185 randomized patients, 173 (93.5%) completed week 16 and 145 (78.4%) entered the open-label extension. Significantly more patients in each risankizumab arm achieved ACR20 at week 16 versus placebo (primary endpoint: pooled arms 1 + 2 [59.5%] versus placebo [35.7%]; treatment difference [90% CI] 24.0 [9.3, 38.7]; P = 0.007). Similarly, significantly more patients in most risankizumab arms achieved ACR20/50/70, PASI75/90/100, MDA, and greater improvements in DAS28(CRP) versus placebo at week 16. These benefits of risankizumab were maintained long term. Treatment-emergent adverse events were comparable across treatment arms. Risankizumab 150 mg was well tolerated over 76 weeks. Conclusions: Risankizumab improved joint and skin symptoms versus placebo in patients with active PsA over 16 weeks; improvements were sustained long term. Risankizumab was well tolerated over the long term with no new safety findings. Trial Registration Numbers: NCT02719171 and NCT02986373. [ABSTRACT FROM AUTHOR]

Fluorescence optical imaging technique (FOI) is a well-established and valid method for visualization of changes in micro vascularization at different organ systems. As increased vascularization is an early feature of joint inflammation, FOI is a promising method to assess arthritis of the hands. But usability of the method is limited to the assessors experience as the measurement of FOI is semi-quantitative using an individual grading system such as the fluorescence optical imaging activity score (FOIAS). The goal of the study was to automatically and thus, objectively analyze the measured fluorescence intensity generated by FOI to evaluate the amount of inflammation of each of the subject's joints focusing on the distinction between normal joint status or arthritis in psoriatic arthritis patients compared to healthy volunteers. Due to the heterogeneity of the pathophysiological perfusion of the hands, a method to overcome the absoluteness of the data by extracting heatmaps out of the image stacks is developed. To calculate a heatmap for one patient, firstly the time series for each pixel is extracted, which is then represented by a feature value. Secondly, all feature values are clustered. The calculated cluster values represent the relativity between the different pixels and enable a comparison of multiple patients. As a metric to quantify the conspicuousness of a joint a score is calculated based on the extracted cluster values. These steps are repeated for a total number of three features. With this method a tendency towards a classification into unaffected and inflamed joints can be achieved. However, further research is necessary to transform the tendency into a robust classification model. [ABSTRACT FROM AUTHOR]

Background and objectives: Our study aimed at examining the long-time inflammatory effects of rheumatoid arthritis (RA) as chronic immune-mediated disease on pain sensation and neuropathy development compared to healthy subjects (HS). Methods: We used the quantitative sensory testing (QST) protocol of the German Research Network on Neuropathic Pain and Electroencephalography (EEG)–based contact heat evoked potentials (CHEPs) before and after topical capsaicin application. We recruited 16 RA patients in remission or low disease activity state (mean age: 59.38 years [± 10.18]) and 16 healthy subjects (mean age: 56.69 years [± 8.92]). Results: The application of capsaicin cream on the thigh provoked a stronger effect in HS for both mechanical and heat pain thresholds (MPT and HPT, resp.), according to the area under the receiver operation characteristic (AUROC) (HS: HPT: 0.8965, MPT: 0.7402; RA: HPT: 0.7012, MPT: 0.6113). We observed contrary effects regarding changes in CHEPs (HS: g*max = − 0.65; RA patients: g*max = 0.72). Conclusion: As the overall effect of topical capsaicin application was higher in HS for QST, we suggest the existence of a sensitization of TRPV1 channels in RA patients caused by long-time chronical inflammation, despite a lack of clinical signs of inflammation due to adequate treatment. The effect in CHEPs probably uncovers neuropathic symptoms. The effect of topical capsaicin on HPTs and CHEPs can act as a marker for the extent of sensitization and the development of neuropathic symptoms. Further studies are needed to prove if our proposed method can act as a marker for the success of anti-inflammatory treatment. Key Points • The effect of topical capsaicin may represent the extent of TRPV1 sensitization in rheumatoid arthritis. • The effect of topical capsaicin on the amplitude level of CHEPs can unmask neuropathic symptoms. • The effect of topical capsaicin on CHEPs and HPTs can show the long-term consequences and the treatment success of RA patients in remission.

Objective ACHILLES aimed to demonstrate efficacy of secukinumab on Achilles' tendon enthesitis in spondyloarthritis (SpA) patients. Methods Patients ≥18 years (n  = 204) with active PsA or axial SpA and heel enthesitis were randomized 1:1 to secukinumab 150/300 mg or placebo up to week 24, and thereafter placebo patients were switched to secukinumab. Results At week 24, a higher, yet statistically non-significant (P  = 0.136), proportion of patients in secukinumab vs placebo reported resolution of Achilles tendon enthesitis in affected foot (42.2% vs 31.4%; odds ratio [OR] = 1.63; 95% CI: 0.87, 3.08). Proportion of patients reporting resolution of enthesitis based on Leeds Enthesitis Index was higher with secukinumab vs placebo (33.3% vs 23.5%; OR = 1.65; 95% CI: 0.85, 3.25) at week 24. Mean change from baseline in heel pain at week 24 was higher in secukinumab patients vs placebo (−2.8 [3.0] vs −1.9 [2.7]). Greater improvements with secukinumab were observed in heel enthesopathy activity and global assessment of disease activity. Imaging evaluation by local reading confirmed heel enthesitis on MRI at screening for all patients. Based on central reading, 56% presented with bone marrow oedema and/or tendinitis; according to Heel Enthesitis MRI Scoring System (HEMRIS) post hoc analysis, 76% had signs of entheseal inflammation while 86% had entheseal inflammation and/or structural changes. Conclusion A substantial proportion of patients showed no signs of inflammation on the centrally read MRIs despite a clinical diagnosis of heel enthesitis, thus highlighting that the discrepancy between the clinical and imaging assessments of enthesitis requires further investigation. Although ACHILLES did not meet the primary end point, the study reported clinically meaningful improvements in patient-related outcomes.

Objective: To evaluate the efficacy and safety of an oral selective tyrosine kinase 2 (TYK2) inhibitor, deucravacitinib, in patients with active psoriatic arthritis (PsA).Methods: In this double-blind, phase II trial, 203 patients with PsA were randomised 1:1:1 to placebo, deucravacitinib 6 mg once a day or 12 mg once a day. The primary endpoint was American College of Rheumatology-20 (ACR-20) response at week 16.Results: ACR-20 response was significantly higher with deucravacitinib 6 mg once a day (52.9%, p=0.0134) and 12 mg once a day (62.7%, p=0.0004) versus placebo (31.8%) at week 16. Both deucravacitinib doses resulted in significant improvements versus placebo (p≤0.05) in the multiplicity-controlled secondary endpoints of change from baseline in Health Assessment Questionnaire-Disability Index and Short Form-36 Physical Component Summary score and in Psoriasis Area and Severity Index-75 response. Improvements were also seen in multiple exploratory endpoints with deucravacitinib treatment. The most common adverse events (AEs) (≥5%) in deucravacitinib-treated patients were nasopharyngitis, upper respiratory tract infection, sinusitis, bronchitis, rash, headache and diarrhoea. There were no serious AEs and no occurrence of herpes zoster, opportunistic infections and major adverse cardiovascular events, or differences versus placebo in mean changes in laboratory parameters with deucravacitinib treatment.Conclusions: Treatment with the selective TYK2 inhibitor deucravacitinib was well tolerated and resulted in greater improvements than placebo in ACR-20, multiplicity-controlled secondary endpoints and other exploratory efficacy measures in patients with PsA. Larger trials over longer periods of time with deucravacitinib are warranted to confirm its safety profile and benefits in PsA.Trial Registration Number: NCT03881059. [ABSTRACT FROM AUTHOR]

Background: For rheumatoid arthritis (RA), the treat-to-target concept suggests attaining remission or at least low disease activity (LDA) after 12 weeks. Objectives: This German, prospective, multicenter, non-interventional study aimed to determine the proportion of patients with RA who achieved their treat-to-target aim after 12 and 24 weeks of etanercept (ETN) treatment in a real-life setting, as opposed to patients achieving their therapeutic target at a later timepoint (week 36 or 52). Methods: A total of 824 adults with a confirmed diagnosis of RA without prior ETN treatment were included. Remission and LDA were defined as DAS28 < 2.6 and DAS28 ≤ 3.2, respectively. Results: The proportion of patients achieving remission was 24% at week 12 and 31% at week 24. The proportion of patients achieving LDA was 39% at week 12 and 45% at week 24. The proportion of patients achieving remission or LDA further increased beyond week 24 up to week 52. Improvement in pain and reduction in concomitant glucocorticoid treatment were observed. Improvements in patient-reported outcomes were also seen in patients who did not reach remission or LDA. No new safety signals were detected. Conclusions: A considerable proportion of patients with RA attained the target of remission or LDA after 12 weeks of ETN treatment. Even beyond that timepoint, the proportion of patients achieving treatment targets continued to increase up to week 52. Trial Registration: ClinicalTrials.gov Identifier: NCT02486302. Plain Language Summary: Physicians measure response to treatment of rheumatoid arthritis using a disease activity score (DAS28). People with a DAS28 of less than 2.6 have very few to no symptoms (also called remission). People with a DAS28 of 3.2 or less, called low disease activity, may experience mild symptoms. When people do not respond to treatment after 12 weeks, it is usually recommended to prescribe a different treatment. Researchers do not know how many people who do not respond after 12 weeks would respond if treatment were continued. A total of 824 German people with rheumatoid arthritis who received a drug called etanercept for up to 52 weeks took part in this study. Researchers wanted to know how many people had remission or low disease activity after 12 weeks and 24 weeks of treatment. After 12 weeks, 24 in 100 people had remission; this increased to 31 in 100 people after 24 weeks. Thirty-nine in 100 people had low disease activity after 12 weeks; this increased to 45 in 100 people after 24 weeks. The number of people with remission or low disease activity increased with longer treatment (up to 52 weeks). People needed less additional treatment with a type of drug called glucocorticoids. The people in this study experienced side effects that were similar to those reported by people who took etanercept in previous studies. The researchers concluded that a considerable proportion of people responded to treatment with etanercept after 12 weeks. This proportion increased when treatment was continued for longer than 12 weeks. [ABSTRACT FROM AUTHOR]

Objective: To evaluate risankizumab, a biological therapy that inhibits interleukin 23, in patients with active psoriatic arthritis (PsA) who have responded inadequately or are intolerant to ≥1 conventional synthetic disease-modifying antirheumatic drug (csDMARD).Methods: In the randomised, placebo-controlled, double-blind KEEPsAKE 1 trial, 964 patients with active PsA were randomised (1:1) to receive risankizumab 150 mg or placebo at weeks 0, 4 and 16. The primary endpoint was the proportion of patients achieving ≥20% improvement in American College of Rheumatology criteria (ACR20) at week 24. Here, we report the results from the 24-week double-blind period; the open-label period with all patients receiving risankizumab is ongoing.Results: At week 24, a significantly greater proportion of patients receiving risankizumab achieved the primary endpoint of ACR20 (57.3% vs placebo, 33.5%; p<0.001). Significant differences were also observed for risankizumab versus placebo for the first eight ranked secondary endpoints, including skin and nail psoriasis endpoints, minimal disease activity and resolution of enthesitis and dactylitis (p<0.001). Adverse events and serious adverse events were reported at similar rates in the risankizumab and placebo groups. Serious infections were reported for 1.0% and 1.2% of patients receiving risankizumab and placebo, respectively. There was one death in the risankizumab group (urosepsis deemed unrelated to the study drug).Conclusions: Risankizumab treatment results in significantly greater improvement of signs and symptoms of PsA compared with placebo and is well tolerated in patients with active PsA who have responded inadequately or are intolerant to ≥1 csDMARD.Trial Registration Number: NCT03675308.

Objectives: To characterize treatment patterns for patients with psoriatic arthritis (PsA) currently receiving any disease-modifying antirheumatic drug (DMARD). Methods: The Strategy for Psoriatic Arthritis In Germany (SPAIG) study was a retrospective observational study conducted from May to November 2017 at 46 rheumatology centers. Current and previous treatment data were collected at a single visit from adult patients with PsA and psoriasis who received DMARD treatment for ≥6 of the previous 12 months. The primary outcome was the proportion of patients receiving a biologic DMARD (bDMARD). Multinomial logistic regression analysis was used to evaluate associations between current characteristics and initial choice of therapy. Results: Mean age of the 316 patients was 55.1 years and mean PsA disease duration was 9.9 years. PsA activity was generally comparable across treatment groups. In this cohort, 57.3% of patients were currently treated with bDMARDs, 37.7% with conventional synthetic DMARDs, and 4.4% with targeted synthetic DMARDs. Almost half (48.4%) of patients reported DMARD modifications in the previous 12 months. Specific comorbidities and patient/disease characteristics were associated with initial therapy. Conclusion: DMARD treatment of PsA is frequently modified, suggesting the need for more effective therapies and assessment tools. [ABSTRACT FROM AUTHOR]

Introduction: Improvements in both musculoskeletal and non-musculoskeletal manifestations are important treatment goals in psoriatic arthritis (PsA). Objective: These post hoc analyses determined whether additional benefits related to various PsA domains are observed in patients simultaneously achieving 50% improvement in American College of Rheumatology criteria (ACR50) and 100% improvement in Psoriasis Area Severity Index (PASI100), the primary endpoint of the SPIRIT-H2H study. Methods: Patients with active PsA and psoriasis in SPIRIT-H2H (N = 566) were categorised into two sets of four response groups irrespective of treatment allocation (approved dosages of ixekizumab or adalimumab): patients who simultaneously achieved ACR50 and PASI100 response, achieved ACR50 response only, achieved PASI100 response only, or did not achieve ACR50 or PASI100 response after 24 and 52 weeks of treatment. Patients achieving simultaneous ACR50 and PASI100 response were compared with the other patient response groups at the corresponding time point for efficacy and health-related quality of life (HRQoL) outcomes. Results: Patients simultaneously achieving ACR50 and PASI100 responses at week 24 or 52 showed higher rates of ACR70 response, minimal disease activity, Disease Activity in Psoriatic Arthritis ≤ 4, resolution of enthesitis and dactylitis, and HRQoL improvement at weeks 24 and 52, respectively, than the other corresponding response groups at both time points. Conclusion: High levels of disease control, such as those obtained with simultaneous achievement of ACR50 and PASI100 response, were linked to better outcomes across a wide range of endpoints that are important for patients with PsA. Patients meeting this combined endpoint showed more comprehensive and thus greater control of disease activity. Trial registration NCT03151551 Key Points • Treatment goals for patients with psoriatic arthritis emphasise the importance of improving both musculoskeletal and non-musculoskeletal manifestations of the disease. • A combined endpoint considering both these manifestations, achievement of at least 50% improvement in American College of Rheumatology criteria and 100% improvement in Psoriasis Area Severity Index, was linked with achievement of a number of other endpoints relevant to psoriatic arthritis, including health-related quality of life that are important to patients with psoriatic arthritis. • Patients meeting the combined endpoint were more likely to achieve a disease state of remission, which is the stated aim of treatment for psoriasis.

Objective To investigate the efficacy and safety of rituximab + LEF in patients with RA. Methods In this investigator-initiated, randomized, double-blind, placebo-controlled phase 3 trial, patients with an inadequate response to LEF who had failed one or more DMARD were randomly assigned 2:1 to i.v. rituximab 1000 mg or placebo on day 1 and 15 plus ongoing oral LEF. The primary efficacy outcome was the difference between ≥50% improvement in ACR criteria (ACR50 response) rates at week 24 (P  ≤ 0.025). Secondary endpoints included ACR20/70 responses, ACR50 responses at earlier timepoints and adverse event (AE) rates. The planned sample size was not achieved due to events beyond the investigators' control. Results Between 13 August 2010 and 28 January 2015, 140 patients received rituximab (n  = 93) or placebo (n  = 47) plus ongoing LEF. Rituximab + LEF resulted in an increase in the ACR50 response rate that was significant at week 16 (32 vs 15%; P  = 0.020), but not week 24 (27 vs 15%; P  = 0.081), the primary endpoint. Significant differences favouring the rituximab + LEF arm were observed in some secondary endpoints, including ACR20 rates from weeks 12 to 24. The rituximab and placebo arms had similar AE rates (71 vs 70%), but the rituximab arm had a higher rate of serious AEs (SAEs 20 vs 2%), primarily infections and musculoskeletal disorders. Conclusion The primary endpoint was not reached, but rituximab + LEF demonstrated clinical benefits vs LEF in secondary endpoints. Although generally well tolerated, the combination was associated with additional SAEs and requires monitoring. Trial registration EudraCT: 2009-015950-39; ClinicalTrials.gov: NCT01244958.

Background: The currently available scoring methods for enthesitis are often measures of pain but not of inflammation at entheseal sites. The Outcome Measures in Rheumatology Clinical Trials (OMERACT) psoriatic arthritis (PsA) magnetic resonance imaging (MRI) scoring system (PsAMRIS) assesses inflammation and damage in PsA and was particularly developed for the hands. The ACHILLES trial used clinical measures for heel enthesitis in combination with MRI scoring based on PsAMRIS.Methods: Patients (age ≥ 18 years) with spondyloarthritis (SpA) and PsA were included in the trial if they presented with clinical and MRI-positive heel enthesitis. MRI of the affected heel was performed at three time points: screening, Week 24 and Week 52. Inflammatory MRI findings (tendinitis, bursitis and bone marrow oedema [BME]) in the area of the Achilles tendon and/or plantar aponeurosis, periarticular inflammation of the ankle joint and heel erosion were assessed qualitatively (absent/present). In addition, BME and bone erosion were quantitatively assessed based on PsAMRIS, where their proportion was compared to the volume of the affected bone. Mean scores of BME and bone erosion quantification were calculated, and the mean composite score (based on PsAMRIS) was calculated based on the individual score of each subject for periarticular inflammation, BME and bone erosion and further extended for bursitis and tendinitis. Modifications to PsAMRIS were introduced by categorising oedema length as ≤/> 0.5 cm and locating bone erosion.Conclusions: In ACHILLES, MRI was used to assess and evaluate heel enthesitis. Due to the lack of a validated scoring system for heel enthesitis at the time of ACHILLES initiation, this trial applied quantitative scoring based on PsAMRIS, with specific adaptations for the heel.Trial Registration: National Clinical Trial Registry, NCT02771210 .

Objective: The goal of this study was to evaluate the long-term impact of adalimumab therapy on work-related outcomes in employed patients with rheumatoid arthritis (RA). Method: We utilized data from an observational cohort of German patients who initiated adalimumab treatment during routine clinical care. Analyses were based on employed patients (part-time or full-time) who continued adalimumab treatment for 24 months. Major outcomes were self-reported sick leave days in the previous 6 months, absenteeism, presenteeism, and total work productivity impairment as assessed by the Work Productivity and Activity Impairment (WPAI) questionnaire and disease activity assessments. The normal number of sick leave days was based on data from the German Federal Statistical Office. Results: Of 783 patients, 72.3% were women, mean age was 47.9 years, and mean disease duration was 7.8 years. At baseline (before adalimumab initiation), 42.9% of patients had higher than normal sick leave days (> 5) in the previous 6 months. During 24 months of adalimumab treatment, 61% of patients with higher than normal sick leave days at baseline returned to normal sick leave values (≤ 5 days/6 months). Overall, mean sick leave days/6 months decreased from 14.8 days at baseline to 7.4 days at month 24. Improvements were observed in WPAI assessments and disease activity measures, although presenteeism levels remained high (32.2% at month 24). Conclusions: Adalimumab treatment was associated with strong and sustained improvements in work-related outcomes in employed patients who continued on adalimumab for 24 months. Presenteeism appears to be the work outcome most resistant to improvement during RA treatment. Trial registration: NCT01076205 Key Points • Long-term adalimumab therapy was associated with sustained improvements in work outcomes in patients with rheumatoid arthritis. • Despite improvements in sick leave days and work absenteeism, presenteeism (impairment while at work) remained relatively high.

This article presents a monitoring system for industrial electrical equipment in a production line, aiming at real-time monitoring of its operational state, allowing machine management and early detection of deviations and failures. The system measures the effective current draw of the monitored equipment using sensors connected to a data concentrator module, which stores the data collected by these sensors and performs preliminary processing before transmission to an Internet of Things platform. Preliminary data processing focuses on analyzing the time series of the electric current values in order to detect the operating state of the monitored machine. This information is then sent over the Internet to an IoT platform for long-term storage, post-processing and real-time visualization of data by end users. When a behavior deviation is detected in current consumption related to some type of potential failure, the system issues alerts and sends additional information to the production line supervisor, for example to proceed with equipment maintenance intervention without impact on production. The availability of full-time data series, as well as the history of all occurrences recorded by the monitoring system, also allow for correlations with data from other sources and their interpretation in contexts other than machine operation or maintenance. The proposed monitoring system provides minimal automation on older machines and opens up the possibility of independent, parallel and non-intrusive monitoring on machines that already have supervisory systems.

Background: Inhibition of interleukin (IL)-1 represents a promising treatment option in adult-onset Still's disease (AOSD).Objective: To investigate the efficacy and safety of canakinumab in patients with AOSD and active joint involvement by means of a multicentre, double-blind, randomised, placebo-controlled trial.Methods: Patients with AOSD and active joint involvement (tender and swollen joint counts of ≥4 each) were treated with canakinumab (4 mg/kg, maximum 300 mg subcutaneous every 4 weeks) or placebo. The primary endpoint was the proportion of patients with a clinically relevant reduction in disease activity at week 12 as determined by the change in disease activity score (ΔDAS28>1.2).Results: At enrolment, patients had high active disease with a mean DAS28(ESR) of 5.4 in the canakinumab and 5.3 in the placebo group, respectively. In the intention-to-treat analysis, 12 patients (67%) in the canakinumab group and 7 patients (41%) in the placebo group fulfilled the primary outcome criterion (p=0.18). In the per-protocol analysis, significantly higher American College of Rheumatology (ACR) 30% (61% vs 20%, p=0.033), ACR 50% (50% vs 6.7%, p=0.009) and ACR 70% (28% vs 0%, p=0.049) response rates were observed in the canakinumab group compared with the placebo group. Two patients in the canakinumab group experienced a serious adverse event.Conclusion: Although the study was terminated prematurely and the primary endpoint was not achieved, treatment with canakinumab led to an improvement of several outcome measures in AOSD. The overall safety findings were consistent with the known profile of canakinumab. Thus, our data support indication for IL-1 inhibition with canakinumab in AOSD. [ABSTRACT FROM AUTHOR]

Objective: The present study was undertaken to evaluate the probability of achieving the Clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) treatment targets of remission or low disease activity (LDA) with apremilast based on disease activity categories and corresponding responses in arthritis and other domains of psoriatic arthritis (PsA) not included in the cDAPSA.Methods: Pooled analyses from the Psoriatic Arthritis Long-term Assessment of Clinical Efficacy studies 1, 2, and 3 were performed. Probability analyses assessing the likelihood of achieving cDAPSA treatment targets by week 52 were performed using multiple imputation for discontinuations and missing values. Longitudinal analyses were performed in patients grouped by cDAPSA category at week 52.Results: Among 494 patients in the probability analyses, 46.9% with moderate disease activity and 24.9% with high disease activity at baseline achieved treatment targets (remission or LDA) by week 52. For patients with moderate disease activity at baseline, small improvements (cDAPSA reductions ≥30%) by week 16 were associated with achieving targets. Patients achieving remission or LDA by week 16 had high probabilities of remaining at treatment targets at week 52. Of 375 patients with cDAPSA components available at week 52, achieving targets with apremilast was associated with continuous disease activity improvements and no or mild arthritis and other PsA manifestations.Conclusion: The probability of achieving treatment targets (remission or LDA) at week 52 was greater for patients with moderate versus high disease activity at baseline. At a mean level, partial improvements by week 16 were associated with achieving treatment targets. Patients receiving apremilast who achieved cDAPSA targets by week 52 also had no or mild arthritis or other PsA manifestations. [ABSTRACT FROM AUTHOR]

Background: Syndrome of synovitis acne pustulosis hyperostosis osteitis (SAPHO) and chronic recurrent multifocal osteomyelitis (CRMO) present two diseases of a dermatologic and rheumatologic spectrum that are variable in manifestation und therapeutic response. Genetic risk factors have long been assumed in both diseases, but no single reliable factor has been identified yet. Therefore, we aimed to clinically characterize a patient group with syndrome of synovitis acne pustulosis hyperostosis osteitis (SAPHO) (n = 47) and chronic recurrent multifocal osteomyelitis (CRMO)/ chronic non-bacterial osteomyelitis (CNO) (n = 9) and analyze a CRMO candidate gene. Methods: Clinical data of all patients were collected and assessed for different combinations of clinical symptoms. SAPHO patients were grouped into categories according to the acronym; disease-contribution by pathogens was evaluated. We sequenced coding exons of FBLIM1. Results: Palmoplantar pustular psoriasis (PPP) was the most common skin manifestation in CRMO/CNO and SAPHO patients; most SAPHO patients had sterno-costo-clavicular hyperostosis. The most common clinical category of the acronym was S_PHO (n = 26). Lack of pathogen detection from bone biopsies was more common than microbial isolation. We did not identify autosomal-recessive FBLIM1 variants. Conclusions: S_PHO is the most common combination of symptoms of its acronym. Genetic analyses of FBLIM1 did not provide evidence that this gene is relevant in our patient group. Our study indicates the need to elucidate SAPHO's and CRMO/CNO's pathogenesis.

Assessment of individual therapeutic responses provides valuable information concerning treatment benefits in individual patients. We evaluated individual therapeutic responses as determined by the Disease Activity Score-28 joints critical difference for improvement (DAS28-dcrit) in rheumatoid arthritis (RA) patients treated with intravenous tocilizumab or comparator anti-tumor necrosis factor (TNF) agents. The previously published DAS28-dcrit value [DAS28 decrease (improvement) ≥ 1.8] was retrospectively applied to data from two studies of tocilizumab in RA, the 52-week ACT-iON observational study and the 24-week ADACTA randomized study. Data were compared within (not between) studies. DAS28 was calculated with erythrocyte sedimentation rate as the inflammatory marker. Stability of DAS28-dcrit responses and European League Against Rheumatism (EULAR) good responses was determined by evaluating repeated responses at subsequent timepoints. A logistic regression model was used to calculate p values for differences in response rates between active agents. Patient-reported outcomes (PROs; pain, global health, function, and fatigue) in DAS28-dcrit responder versus non-responder groups were compared with an ANCOVA model. DAS28-dcrit individual response rates were 78.2% in tocilizumab-treated patients and 58.2% in anti-TNF-treated patients at week 52 in the ACT-ion study (p = 0.0001) and 90.1% versus 59.1% at week 24 in the ADACTA study (p < 0.0001). DAS28-dcrit responses showed greater stability over time (up to 52 weeks) than EULAR good responses. For both active treatments, DAS28-dcrit responses were associated with statistically significant improvements in mean PRO values compared with non-responders. The DAS28-dcrit response criterion provides robust assessments of individual responses to RA therapy and may be useful for discriminating between active agents in clinical studies and guiding treat-to-target decisions in daily practice.

Objectives: To compare efficacy and safety of ixekizumab (IXE) to adalimumab (ADA) in biological disease-modifying antirheumatic drug-naïve patients with both active psoriatic arthritis (PsA) and skin disease and inadequate response to conventional synthetic disease-modifying antirheumatic drug (csDMARDs).Methods: Patients with active PsA were randomised (1:1) to approved dosing of IXE or ADA in an open-label, head-to-head, blinded assessor clinical trial. The primary objective was to evaluate whether IXE was superior to ADA at week 24 for simultaneous achievement of a ≥50% improvement from baseline in the American College of Rheumatology criteria (ACR50) and a 100% improvement from baseline in the Psoriasis Area and Severity Index (PASI100). Major secondary objectives, also at week 24, were to evaluate whether IXE was: (1) non-inferior to ADA for achievement of ACR50 and (2) superior to ADA for PASI100 response. Additional PsA, skin, treat-to-target and quality-of-life outcome measures were assessed at week 24.Results: The primary efficacy endpoint was met (IXE: 36%, ADA: 28%; p=0.036). IXE was non-inferior for ACR50 response (IXE: 51%, ADA: 47%; treatment difference: 3.9%) and superior for PASI100 response (IXE: 60%, ADA: 47%; p=0.001). IXE had greater response versus ADA in additional PsA, skin, nail, treat-to-target and quality-of-life outcomes. Serious adverse events were reported in 8.5% (ADA) and 3.5% (IXE) of patients.Conclusions: IXE was superior to ADA in achievement of simultaneous improvement of joint and skin disease (ACR50 and PASI100) in patients with PsA and inadequate response to csDMARDs. Safety and tolerability for both biologicals were aligned with established safety profiles. [ABSTRACT FROM AUTHOR]
