Efficacy and Safety of Tofacitinib in Patients with Psoriatic Arthritis or Ankylosing Spondylitis by Cigarette Smoking Status.

INTRODUCTION: Routine care studies of psoriatic arthritis (PsA) and ankylosing spondylitis (AS) demonstrated attenuated responses to tumor necrosis factor inhibitors in current/past versus never smokers. This post hoc analysis assessed tofacitinib efficacy and safety in patients with PsA or AS by cigarette smoking status at trial screening. METHODS: Pooled data from phase 3 and long-term extension (safety only) PsA trials and phase 2 and 3 AS trials were assessed by current/past versus never smoker status. Analysis included efficacy and safety data for tofacitinib 5 (PsA/AS) and 10 (PsA only) mg twice daily (BID) or placebo, and safety data in AS for tofacitinib 2 and 10 mg BID. Efficacy outcomes included American College of Rheumatology ≥ 50% responses (ACR50) and minimal disease activity (MDA) responses to month (M)6/M3 (tofacitinib/placebo) in PsA; and ≥ 40% improvement in Assessment of SpondyloArthritis international Society responses (ASAS40) and AS Disease Activity Score (ASDAS) < 2.1 responses to week (W)16 in AS. Safety was assessed to M48/W48 (PsA/AS), adjusted for treatment/smoking status/median body mass index (BMI) status/sex/trial/treatment-smoking status interaction. RESULTS: PsA/AS cohorts included 342/178 current/past and 572/194 never smokers. Tofacitinib efficacy was generally greater versus placebo to M3/W6 (PsA/AS), and comparable in current/past and never smokers to M6/W16 (PsA/AS). In patients receiving ≥ 1 tofacitinib dose, adjusted treatment-emergent adverse event (TEAE)/serious AE (SAE)/discontinuation due to AE incidence rates (IRs) to M48 in PsA were higher in current/past versus never smokers; adjusted IRs to W48 in AS were higher in current/past versus never smokers for TEAEs, but similar for SAEs/discontinuation due to AEs. CONCLUSIONS: In both patients with PsA and AS, tofacitinib efficacy was greater versus placebo, and comparable across smoking categories. Adjusted IRs were higher in current/past versus never smokers for TEAEs, SAEs, discontinuation due to AEs in PsA, and for TEAEs in AS, complementing reports of associations between smoking and comorbidities in spondyloarthritis. Findings support increased surveillance/caution for patients with PsA or AS with smoking history.

Early Improvements with Guselkumab Associate with Sustained Control of Psoriatic Arthritis: Post hoc Analyses of Two Phase 3 Trials.

INTRODUCTION: Patterns of treatment response can inform clinical decision-making. This study assessed the course and impact of achieving minimal clinically important improvement (MCII) in clinical measures and patient-reported outcomes (PROs) with guselkumab in patients with active psoriatic arthritis (PsA). METHODS: Post hoc analyses evaluated 1120 patients with PsA receiving guselkumab every 4 or 8 weeks (Q4W/Q8W) or placebo from DISCOVER-1 (31% tumor necrosis factor inhibitor-experienced) and DISCOVER-2 (biologic-naïve). Achievement of MCII in clinical Disease Activity Index for PsA (cDAPSA), patient global assessment (PtGA) of arthritis, PtGA of psoriasis, patient-reported pain, Functional Assessment of Chronic Illness Therapy-Fatigue, Health Assessment Questionnaire-Disability Index, 36-item Short-Form Health Survey Physical Component Summary score, PtGA Arthritis + Psoriasis, and PsA Disease Activity Score (PASDAS) was compared between the guselkumab and placebo groups using Cox regression. Logistic regression adjusting for baseline factors evaluated associations between early (W4/W8) MCII achievement and stringent response (≥%50/%70 improvement in American College of Rheumatology response criteria, cDAPSA low disease activity [LDA], PASDAS LDA, and minimal disease activity) at W24/W52 among guselkumab-randomized patients. RESULTS: Among patients with highly active PsA (baseline cDAPSA = 44.1-45.0, PASDAS = 6.4-6.5), times to MCII were significantly faster for guselkumab vs. placebo (hazard ratios 1.3-2.5; P < 0.05). Across measures, at first timepoint assessed, MCII rates were significantly higher with guselkumab (Q4W/Q8W 28-68%/29-65%) vs. placebo (19-47%; both P < 0.05). Early (W4/W8) MCII with guselkumab associated with higher odds of achieving stringent responses at W24/W52 (odds ratios 1.4-17.2/1.4-5.4). CONCLUSIONS: In a mixed PsA population, significant proportions of patients treated with guselkumab achieved early (W4/W8) MCII across clinical and PRO measures, which associated with a higher likelihood of attaining clinically relevant improvements and low levels of disease activity at W24/W52. TRIAL REGISTRATION: DISCOVER-1 (NCT03162796). DISCOVER-2 (NCT03158285).

GRAPPA 2023: Major Projects, Key Advances, and Milestones.

At the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) 2023 annual meeting, members were updated on a number of ongoing activities during the key project update session. These activities included the Axial Involvement in Psoriatic Arthritis (AXIS) cohort, the Axial Psoriatic Arthritis Molecular and Clinical Characterization study, the Diagnostic Ultrasound Enthesitis Tool (DUET) study, the Sex- and Gender-Based Analysis of the Effectiveness of Advanced Therapies in Psoriatic Arthritis (SAGE-PsA) study, the Health Initiatives in Psoriasis and Psoriatic Arthritis Consortium European States (HIPPOCRATES), the GRAPPA slide library, and the GRAPPA treatment recommendations.

Deciphering difficult-to-treat psoriatic arthritis (D2T-PsA): a GRAPPA perspective from an international survey of healthcare professionals.

Objectives: This study contributes to the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA)'s effort to define 'difficult-to-treat' PsA (D2T-PsA), leveraging insights of healthcare professionals who are GRAPPA members. The primary objective is to inform GRAPPA's D2T PsA project, ensuring the consensus definition reflects clinical experience and expertise. Methods: An online survey was conducted among GRAPPA's healthcare professionals managing PsA patients. The survey covered demographic details, structured questions, and open-ended queries to gather comprehensive insights into the experts' viewpoints. Results: About 223 physicians completed the survey, comprising 179 (80.2%) rheumatologists and 40 (17.9%) dermatologists. The majority, 184 (82.5%), favoured establishing distinct definitions for D2T-PsA and complex-to-manage PsA (C2M-PsA). Furthermore, 202 (90.5%) supported a definition that includes objective inflammation signs (clinical, laboratory, imaging, among others). However, opinions varied on the criteria for prior treatment failures, with most (93, 41.7%) favouring a definition that includes at least one conventional synthetic disease-modifying anti-rheumatic drug and two or more biological- or targeted-synthetic-DMARDs with different mechanisms of action. Conclusion: The survey reveals a majority opinion among GRAPPA experts favouring the differentiation between D2T-PsA and C2M-PsA, and the inclusion of objective inflammatory markers in these definitions. However, there is less than 50% agreement on the specific treatment failure criteria, particularly regarding the number of therapies needed to classify PsA as D2T. These findings suggest a need for continued discussion to reach a more unified approach in defining D2T-PsA, reflecting the complexity of the condition.

BASDAI versus ASDAS in evaluating axial involvement in patients with psoriatic arthritis: a pooled analysis of two phase 3 studies.

Objective: In the absence of axial psoriatic arthritis (axPsA)-specific tools, the BASDAI and Ankylosing Spondylitis Disease Activity Score (ASDAS) are used to assess axial symptoms in patients with PsA. Here, we assessed the performance of BASDAI and ASDAS in patients with PsA. Methods: Patients with active PsA in DISCOVER-1 and DISCOVER-2 (ClinicalTrials.gov: NCT03162796 and NCT03158285, respectively) with or without axPsA but with available baseline BASDAI information were analysed; those with investigator-identified axial symptoms and imaging-confirmed sacroiliitis comprised the axPsA cohort. Correlations between BASDAI/ASDAS and clinical variables were assessed with Pearson's coefficient (r). Longitudinal effects of enthesitis (Leeds Enthesitis Index [LEI]), swollen joint count and presence versus absence of axPsA on BASDAI/ASDAS (normalized 0-10 scale) were analysed with mixed models for repeated measures. Results: At baseline in the axPsA (n = 312) and non-axPsA (n = 124) cohorts, BASDAI scores showed no or weak correlation with swollen joint count (0.18-0.20), tender joint count (0.12-0.29), LEI (-0.04 to 0.24) and physician global assessment (0.35-0.43); moderate correlation with fatigue (both -0.56); and strong correlation with patient global assessment of disease activity (0.62-0.69) and patient-reported pain (0.66-0.70). Similar correlations were observed for ASDAS. Axial involvement versus non-involvement was associated with higher BASDAI scores and ASDAS (all ß ≥ 0.5), without differences between instruments; longitudinal associations between swollen joint count (ß ≤ 0.06)/LEI (ß ≤ 0.19) and BASDAI/ASDAS were clinically unimportant. Conclusion: BASDAI and ASDAS performed similarly in patients with active PsA and axial involvement, independent of peripheral disease involvement, supporting their performance in assessing axial disease activity.

Pan American League of Associations for Rheumatology Recommendations for the Treatment of Psoriatic Arthritis.

OBJECTIVE: Psoriatic arthritis (PsA) is chronic disease that compromises multiple domains and might be associated with progressive joint damage, increased mortality, functional limitation, and considerably impaired quality of life. Our objective was to generate evidence-based recommendations on the management of PsA in Pan American League of Associations for Rheumatology (PANLAR) countries. METHODS: We used the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE)-ADOLOPMENT approach to adapt the 2019 recommendations of the European Alliance of Associations for Rheumatology. A working group consisting of rheumatologists from various countries in Latin America identified relevant topics for the treatment of PsA in the region. The methodology team updated the evidence and synthesized the information used to generate the final recommendations. These were then discussed and defined by a panel of 31 rheumatologists from 15 countries. RESULTS: Theses guidelines report 15 recommendations addressing therapeutic targets, use of antiinflammatory agents and corticosteroids, treatment with disease-modifying antirheumatic drugs (conventional synthetic, biologic, and targeted synthetic), therapeutic failure, optimization of biologic therapy, nonpharmacological interventions, assessment tools, and follow-up of patients with PsA. CONCLUSION: Here we present a set of recommendations to guide decision making in the treatment of PsA in Latin America, based on the best evidence available, considering resources, medical expertise, and the patient's values and preferences. The successful implementation of these recommendations should be based on clinical practice conditions, healthcare settings in each country, and a tailored evaluation of patients.

'It's about time'. Dissemination and evaluation of a global health systems strengthening roadmap for musculoskeletal health - insights and future directions.

Actions towards the health-related Sustainable Development Goal 3.4 typically focus on non-communicable diseases (NCDs) associated with premature mortality, with less emphasis on NCDs associated with disability, such as musculoskeletal conditions-the leading contributor to the global burden of disability. Can systems strengthening priorities for an underprioritised NCD be codesigned, disseminated and evaluated? A 'roadmap' for strengthening global health systems for improved musculoskeletal health was launched in 2021. In this practice paper, we outline dissemination efforts for this Roadmap and insights on evaluating its reach, user experience and early adoption. A global network of 22 dissemination partners was established to drive dissemination efforts, focussing on Africa, Asia and Latin America, each supported with a suite of dissemination assets. Within a 6-month evaluation window, 52 Twitter posts were distributed, 2195 visitors from 109 countries accessed the online multilingual Roadmap and 138 downloads of the Roadmap per month were recorded. Among 254 end users who answered a user-experience survey, respondents 'agreed' or 'strongly agreed' the Roadmap was valuable (88.3%), credible (91.2%), useful (90.1%) and usable (85.4%). Most (77.8%) agreed or strongly agreed they would adopt the Roadmap in some way. Collection of real-world adoption case studies allowed unique insights into adoption practices in different contexts, settings and health system levels. Diversity in adoption examples suggests that the Roadmap has value and adoption potential at multiple touchpoints within health systems globally. With resourcing, harnessing an engaged global community and establishing a global network of partners, a systems strengthening tool can be cocreated, disseminated and formatively evaluated.

Pan American League of Associations for Rheumatology recommendations for the management of axial spondyloarthritis.

Axial spondyloarthritis (axSpA) comprises a spectrum of chronic inflammatory manifestations affecting the axial skeleton and represents a challenge for diagnosis and treatment. Our objective was to generate a set of evidence-based recommendations for the management of axSpA for physicians, health professionals, rheumatologists and policy decision makers in Pan American League of Associations for Rheumatology (PANLAR) countries. Grading of Recommendations, Assessment, Development and Evaluation-ADOLOPMENT methodology was used to adapt existing recommendations after performing an independent systematic search and synthesis of the literature to update the evidence. A working group consisting of rheumatologists, epidemiologists and patient representatives from countries within the Americas prioritized 13 topics relevant to the context of these countries for the management of axSpA. This Evidence-Based Guideline article reports 13 recommendations addressing therapeutic targets, the use of NSAIDs and glucocorticoids, treatment with DMARDs (including conventional synthetic, biologic and targeted synthetic DMARDs), therapeutic failure, optimization of the use of biologic DMARDs, the use of drugs for extra-musculoskeletal manifestations of axSpA, non-pharmacological interventions and the follow-up of patients with axSpA.

Proceedings of the GRAPPA 2022 Executive Retreat.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) leadership congregated for a strategic planning meeting before the 2022 GRAPPA annual meeting in New York, USA. Meeting aims were to review GRAPPA's performance in relation to its 2016 goals and identify successes and areas for further improvement, identify key GRAPPA priorities and activities for the next 5 years, and explore committee structures to best support these aims.

Can Early Aggressive Treatment of Psoriasis Prevent Psoriatic Arthritis? A Debate at the GRAPPA Annual Meeting.

In recent years, a number of studies have examined risk factors for development of psoriatic arthritis (PsA) among patients with PsO. Most recently, 5 studies have examined the effect of biologic therapy on the development of PsA. However, the results have been mixed, with 3 studies suggesting a lower risk for PsA among those using a biologic therapy and 2 suggesting a higher risk for PsA. At the 2022 Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) meeting, Drs. Enrique Soriano and Alexis Ogdie conducted a debate to discuss the arguments for and against the use of biologic therapies in PsO for the purpose of preventing PsA.

In this brief report, winners of the 2020 and 2021 awards present the results of their pilot projects.

Telehealth and Telemedicine in Latin American Rheumatology, a New Era After COVID-19.

ABSTRACT: Telemedicine is the delivery of health care services by health care professionals using information and communication technologies to exchange valid information for the diagnosis, treatment, and prevention of diseases. Telemedicine was further developed in Latin America during the COVID-19 (coronavirus disease 2019) pandemic, becoming the first line of defense for health professionals to stop the spread of infections and allow them to continue the care of their patients. During the pandemic, 79% of rheumatologists in Latin America reported the use of remote communication, the most frequent being the use of phone calls and WhatsApp voice messages. In contrast, 84% of the patients reported that telemedicine was appropriate for them during the pandemic, but only 54% considered telemedicine to be a valid option for rheumatic health care after the pandemic. Telemedicine and telehealth have advantages such as lower costs, improved access in rural areas, shortage of care providers, and reduction in waiting time for appointments. However, it also has some challenges, such as legal, technological, and organizational barriers. In this review, we explore the current state of telemedicine in Latin America and discuss its future.

Multidomain Efficacy and Safety of Guselkumab Through 1 Year in Patients With Active Psoriatic Arthritis With and Without Prior Tumor Necrosis Factor Inhibitor Experience: Analysis of the Phase 3, Randomized, Placebo-Controlled DISCOVER-1 Study.

OBJECTIVE: To evaluate efficacy and safety of the interleukin-23p19-subunit inhibitor, guselkumab, in DISCOVER-1 patients with active psoriatic arthritis (PsA) by prior use of tumor necrosis factor inhibitor (TNFi). METHODS: The phase 3, randomized, placebo-controlled DISCOVER-1 study enrolled patients with active PsA (swollen joint count ≥3, tender joint count ≥3, and C-reactive protein level ≥ 0.3 mg/dl) despite standard therapies; approximately one-third could have received two or fewer prior TNFi. Patients were randomized to 100 mg of guselkumab every 4 weeks (Q4W); 100 mg of guselkumab at week 0, at week 4, and every 8 weeks (Q8W); or placebo with crossover to guselkumab Q4W at week 24. Efficacy end points of ≥20% and ≥50% improvement in individual American College of Rheumatology (ACR) criteria and achieving the minimal disease activity (MDA) components were summarized by prior TNFi status. RESULTS: In DISCOVER-1, 118 (31%) patients previously received one or two TNFi. As previously reported, rates for acheiving ≥20% improvement in the composite ACR response at week 24 and week 52 were similar in TNFi-naive and TNFi-experienced patients randomized to guselkumab Q4W (76% and 68%, respectively) and Q8W (61% and 58%, respectively). Similar trends were observed for response rates of ≥20% and ≥50% improvement in individual ACR criteria and for achieving individual MDA components at week 24; TNFi-naive patients were more likely to achieve end points related to physical function and pain than TNFi-experienced patients. Overall, response rates were maintained or increased through week 52 regardless of prior TNFi use. Through week 60 in guselkumab-treated TNFi-naive and TNFi-experienced patients, 62% and 64%, respectively, reported one or more adverse events (AEs); 4% and 6% had serious AEs, respectively. CONCLUSION: Through 1 year, 100 mg of guselkumab Q4W and Q8W provided sustained improvements across multiple domains in both TNFi-naive and TNFi-experienced patients with active PsA.

Characteristics associated with poor COVID-19 outcomes in people with psoriasis, psoriatic arthritis and axial spondyloarthritis: data from the COVID-19 PsoProtect and Global Rheumatology Alliance physician-reported registries.

OBJECTIVES: To investigate factors associated with severe COVID-19 in people with psoriasis (PsO), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA). METHODS: Demographic data, clinical characteristics and COVID-19 outcome severity of adults with PsO, PsA and axSpA were obtained from two international physician-reported registries. A three-point ordinal COVID-19 severity scale was defined: no hospitalisation, hospitalisation (and no death) and death. ORs were estimated using multivariable ordinal logistic regression. RESULTS: Of 5045 cases, 18.3% had PsO, 45.5% PsA and 36.3% axSpA. Most (83.6%) were not hospitalised, 14.6% were hospitalised and 1.8% died. Older age was non-linearly associated with COVID-19 severity. Male sex (OR 1.54, 95% CI 1.30 to 1.83), cardiovascular, respiratory, renal, metabolic and cancer comorbidities (ORs 1.25-2.89), moderate/high disease activity and/or glucocorticoid use (ORs 1.39-2.23, vs remission/low disease activity and no glucocorticoids) were associated with increased odds of severe COVID-19. Later pandemic time periods (ORs 0.42-0.52, vs until 15 June 2020), PsO (OR 0.49, 95% CI 0.37 to 0.65, vs PsA) and baseline exposure to TNFi, IL17i and IL-23i/IL-12+23i (OR 0.57, 95% CI 0.44 to 0.73; OR 0.62, 95% CI 0.45 to 0.87; OR 0.67, 95% CI 0.45 to 0.98; respectively; vs no disease-modifying antirheumatic drug) were associated with reduced odds of severe COVID-19. CONCLUSION: Older age, male sex, comorbidity burden, higher disease activity and glucocorticoid intake were associated with more severe COVID-19. Later pandemic time periods, PsO and exposure to TNFi, IL17i and IL-23i/IL-12+23i were associated with less severe COVID-19. These findings will enable risk stratification and inform management decisions for patients with PsO, PsA and axSpA during COVID-19 waves or similar future respiratory pandemics.

Prognostic factors associated with advanced chronic kidney disease in a cohort of patients with ANCA vasculitis and renal involvement.

OBJECTIVE: The aim of this study was to evaluate prognostic factors associated with advanced chronic kidney disease (ACKD) in a cohort of patients with ANCA-associated vasculitis and renal involvement. METHODS: Observational retrospective study. We included patients with biopsy-proven ANCA glomerulonephritis (GN) diagnosed between 2001 and 2016, with at least 1-year follow-up. Data were recorded at diagnosis, end of induction, after 12 months of treatment, and at the end of follow-up. We analysed clinical-analytical data and renal histopathology, as well as treatments, dialysis requirement, relapses and death. Univariate analysis was performed to identify factors associated with long-term ACKD (eGFR < 30 ml/min). Multivariate analysis using an alternative outcome (eGFR at the end of follow-up) was performed. Diagnostic accuracy for ACKD of each predictor variable was compared using AUC of ROC curves. RESULTS: Sixty patients were included: 17 GPA, 14 MPA, 5 EGPA, and 24 RLV. Forty-six patients were women (76.7%). Mean age at diagnosis was 67.8 years (SD 13.1), and median follow-up time was 4.2 years (IQR 2.2-6.8). At the end of follow-up, 12 patients (20.0%) had an eGFR < 30 ml/min. Univariate analysis showed a statistically significant association of ACKD with sclerotic class biopsy (OR 7.17, 95% CI 1.34-38.31), 12-month proteinuria (OR 5.16, 95% CI 1.16-22.87), and creatinine at diagnosis (OR 1.24, 95% CI 1.02-1.52), end of induction (OR 15.40, 95% CI 2.41-98.28), and after 12 months (OR 19.25, 95% CI 2.75-134.92). In the multivariate analysis, eGFR at baseline (< 0.001), after 6 months (< 0.001) and 12 months of treatment (< 0.001), remained statistically associated with eGFR at the end of follow-up. The best diagnostic accuracy in ROC curves was shown by serum creatinine at the end of induction treatment (AUC 0.93) and after 12 months (AUC 0.94). CONCLUSION: In this cohort of patients with ANCA GN, creatinine and eGFR at baseline and after 6 and 12 months of treatment were the best predictors of ACKD at the end of follow-up.

Management of Peripheral Arthritis in Patients With Psoriatic Arthritis: An Updated Literature Review Informing the 2021 GRAPPA Treatment Recommendations.

OBJECTIVE: We aimed to compile evidence for the efficacy and safety of therapeutic options for the peripheral arthritis domain of psoriatic arthritis (PsA) for the revised 2021 Group in Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendations. METHODS: A working group consisting of clinicians and patient research partners was convened. We reviewed the evidence from new randomized controlled trials (RCTs) for PsA treatment from February 19, 2013, to August 28, 2020. We used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE)-informed approach to derive evidence for the classes of therapeutic options for 3 patient groups: (1) naïve to treatment, (2) inadequate response to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), and (3) inadequate response to biologic DMARDs (bDMARDs). Recommendations were derived through consensus meetings. RESULTS: The evidence review included 69 RCTs. We derived GRADE evidence for each class of therapeutic options and achieved consensus for the recommendations. For patients naïve to treatment, the working group strongly recommends csDMARDs (methotrexate, sulfasalazine, leflunomide) and phosphodiesterase 4 inhibitors, and emphasizes regular assessment and early escalation to achieve treatment target. bDMARDs (tumor necrosis factor inhibitors [TNFi], interleukin 17 inhibitors [IL-17i], IL-12/23i, IL-23i) and Janus kinase inhibitors (JAKi) are also strongly recommended. For patients with inadequate response to csDMARDs, we strongly recommend TNFi, IL-17i, IL-12/23i, IL-23i, and JAKi. For those who had prior experience with bDMARDs, we strongly recommend a second TNFi, IL-17i, IL-23i, and JAKi. The evidence supporting nonpharmacological interventions was very low. An expert panel conditionally recommends adequate physical activity, smoking cessation, and diet to control weight gain. CONCLUSION: Evidence supporting optimal therapy for the peripheral arthritis domain of PsA was compiled for the revised 2021 GRAPPA treatment recommendations.
