ObjectiveTo compare the relative efficacy of current and investigational biologic and oral small molecule (OSM) treatments for active ankylosing spondylitis (AS).MethodsA systematic literature review was conducted to identify all phase 2/3 randomized trials of interest in patients with AS. Outcomes assessed were ≥ 20% improvement in the Assessment of Spondyloarthritis International Society Criteria (ASAS20) and change from baseline in Bath Ankylosing Spondylitis Functional Index (BASFI) and C-reactive protein (CRP) at weeks 12-16. Bayesian network meta-analyses were conducted for outcomes using a random effects model. Baseline-risk adjustment was also conducted to account for differences in placebo response across studies. Surface Under the Cumulative Ranking curve (SUCRA) values are reported, reflecting the relative probability that intervention was the best of all interventions.ResultsThe investigational agent tofacitinib 5 mg was the top-ranked treatment (SUCRA, 93%) for ASAS20 response, followed by intravenous (IV) golimumab 2 mg/kg (90%). Golimumab IV 2 mg/kg and infliximab 5 mg/kg were the top two ranked treatments for change from baseline in BASFI (golimumab IV, 81%; infliximab, 80%) and change from baseline in CRP (infliximab, 90%; golimumab IV, 82%).ConclusionsTwo approved therapies (golimumab IV, infliximab) and one investigational product ranked highest for efficacy in AS. Key Points • Although golimumab IV, infliximab, and tofacitinib ranked highest for efficacy in AS, differences in efficacy between approved and investigational therapies were not statistically significant.

Introduction: Psoriatic arthritis (PsA) is a chronic, multidomain, inflammatory disease requiring long-term treatment. Guselkumab, a fully human interleukin [IL]-23p19-subunit inhibitor, and the IL-17A inhibitors (IL-17Ai) ixekizumab and secukinumab are approved by the US Food and Drug Administration (FDA) for adults with active PsA. Real-world data evaluating on-label treatment persistence is an important consideration for patients., Methods: This retrospective claim-based analysis (IQVIA PharMetrics® Plus) included adults with PsA receiving guselkumab or their first subcutaneous (SC) IL-17Ai (ixekizumab/secukinumab) per FDA label ("on-label") between July 14, 2020, and June 30, 2022. Baseline demographic and disease characteristics were collected in the 12 months preceding the index date (date of first guselkumab or SC IL-17Ai claim); follow-up extended through the earlier of the end of continuous insurance eligibility or end of data availability. Baseline characteristics were balanced between the cohorts by propensity score weighting (standardized mortality ratio [SMR]). Discontinuation was defined as a gap 2 × the FDA-approved maintenance dosing interval (guselkumab:112 days; SC IL-17Ai: 56 days); on-label persistence in the weighted cohorts was assessed using Kaplan-Meier curves and compared with a Cox proportional hazards model., Results: Weighted demographic and disease characteristics were well balanced between the cohorts (guselkumab: N = 910, mean age = 50.4 years, 60.4% female; SC IL-17Ai: N = 2740, mean age = 50.2, 59.4% female). At 12 months, the guselkumab cohort was 1.85 × more likely to remain persistent with on-label therapy vs the SC IL-17Ai cohort (p < 0.001); median time to discontinuation was not reached for guselkumab and was 12.3 months for SC IL-17Ai. At 3, 6, 9, and 12 months, persistence rates in the weighted cohorts were higher with guselkumab than with SC IL-17Ai (p < 0.001)., Conclusion: In this real-world claims data analysis in adults with PsA, on-label persistence rates were statistically significantly higher with guselkumab, as early as 3 months, with ~ 2 × greater likelihood of persistence at 12 months relative to SC IL-17Ai., Competing Interests: Declarations.

Background: Guselkumab (human monoclonal antibody) selectively inhibits the interleukin (IL)-23p19 subunit., Objectives: Assess the longer-term pharmacodynamic effects of guselkumab and explore associations between such effects and clinical responses in patients with active psoriatic arthritis (PsA)., Design: DISCOVER-2 randomized 739 biologic-naïve patients with active PsA (swollen/tender joint counts each ⩾5, C-reactive protein (CRP) ⩾0.6 mg/dL) to guselkumab (100 mg every 4 weeks (Q4W) or at Weeks 0, 4, and then Q8W) or placebo. Guselkumab-randomized participants with available serum biomarker data (randomly selected to reflect demographic and disease characteristics of the DISCOVER-2 population) comprised inflammatory ( N  = 100) and collagen ( N  = 178) biomarker cohorts., Methods: Pharmacodynamic effects of guselkumab through 2 years on inflammatory and collagen biomarker levels (general linear model) and associations between biomarkers and improvements in composite measures of joint, skin, and overall disease activity (Spearman linear regression) through 2 years were assessed. The relationship between the pharmacodynamic effects of guselkumab and achieving ⩾50% improvement in the American College of Rheumatology response criteria (ACR50) was assessed using a general linear model., Results: With guselkumab, pharmacodynamic effects on inflammatory (CRP, IL-6, serum amyloid A (SAA), IL-17A, IL-17F, IL-22, and beta-defensin 2 (BD-2)) and collagen (matrix metalloproteinase-degradation type I, III, IV, and VI collagen (C1M, C3M, C4M, and C6M)) biomarker levels were sustained or enhanced through Week 100. Throughout follow-up timepoints (Week 24/52/100), decreases in CRP, IL-6, C1M, and C6M levels correlated ( r  = 0.26-0.30; p  < 0.05) with improved joint disease activity (Disease Activity in Psoriatic Arthritis); decreases in IL-17A, IL-17F, IL-22, and BD-2 levels correlated ( r  = 0.34-0.58; p  < 0.05) with improved skin disease (Psoriasis Area and Severity Index); and decreases in C1M, C3M, C4M, and C6M correlated ( r  = 0.27-0.31; p  < 0.05) with improved overall disease activity (Psoriatic Arthritis Disease Activity Score). Significantly ( p  < 0.05) greater reductions from baseline at Week 100 in CRP, IL-6, SAA, and C1M levels were observed in participants improving from Week 24 ACR50 nonresponse to Week 100 ACR50 response and were accompanied by a significant decrease in C1M from Week 24 to Week 100 versus nonresponders at both Weeks 24 and 100., Conclusion: In biologic-naïve participants with active PsA, guselkumab elicited substantial and enduring reductions in biomarkers that were associated with durable improvements in joint, skin, and overall disease activity through 2 years of DISCOVER-2., Trial Registration: NCT03158285 (clinicaltrials.gov identifier)., Competing Interests: SS: research support from Amgen, Boehringer Ingelheim, Bristol Myers Squibb, Eli Lilly, GlaxoSmithKline, Janssen, and UCB; honoraria/speaker fees from AbbVie, Amgen, AstraZeneca, Eli Lilly, GlaxoSmithKline, Janssen, Teijin Pharma, and UCB.

Objective: Group-level analyses from the phase 3 DISCOVER-2 trial of guselkumab demonstrated robust and durable improvements across psoriatic arthritis (PsA) domains. To specifically evaluate continuous disease control in individual patients, persistence of clinically relevant improvements was assessed, both at consecutive guselkumab dosing visits and over time., Methods: Post hoc analyses included biologic-naïve patients randomized to 100 mg of guselkumab at week 0, week 4, and then every 8 weeks (Q8W). Improvements in joint (minimal clinically important improvement [MCII] in Disease Activity Index for PsA [DAPSA; ≥7.25], clinical DAPSA [cDAPSA; ≥5.7]), skin (Investigator's Global Assessment [IGA] 0/1), and overall disease activity (patient global assessment of arthritis and psoriasis [PtGA Arthritis+Psoriasis; MCII ≥ 15 mm], PsA Disease Activity Score [PASDAS; MCII ≥ 0.8]) were assessed. Proportions of patients with maintenance of DAPSA and cDAPSA MCII at consecutive Q8W guselkumab dosing visits (ie, at weeks 4 and 12, weeks 12 and 20, etc through week 52) and patient-level durability of response through week 100 (Kaplan-Meier) were determined., Results: Among 248 patients randomized to guselkumab Q8W, 93% to 99% maintained clinical improvement in joint disease at consecutive Q8W dosing visits through week 52 across time periods. Among guselkumab patients achieving MCII by week 24, estimated probabilities of maintenance of clinical improvement 100 weeks post achievement ranged from 68% (IGA 0/1) to 89% (PASDAS MCII). Median times to loss of improvement were not reached; estimated mean weeks of maintenance of improvement were 58.6, 52.4, 75.7, 83.6, and 76.7, respectively, for DAPSA, cDAPSA, IGA, PtGA Arthritis+Psoriasis, and PASDAS., Conclusion: Guselkumab provided highly durable patient-level improvements, both at consecutive Q8W dosing visits for joint disease activity and over time across PsA domains according to physician- and patient-driven assessments., (© 2024 The Author(s).

Background: Treatment persistence among patients with psoriatic arthritis (PsA) is essential for achieving optimal treatment outcomes. Guselkumab, a fully human interleukin-23p19-subunit inhibitor, was approved by the United States (US) Food and Drug Administration for the treatment of active PsA in July 2020, with a dosing regimen of 100 mg at week 0, week 4, then every 8 weeks. In the Phase 3 DISCOVER-1 and DISCOVER-2 studies of patients with active PsA, 94% of guselkumab-randomized patients completed treatment through 1 year and 90% did so through 2 years (DISCOVER-2). Real-world evidence is needed to compare treatment persistence while following US prescribing guidelines (i.e., on-label persistence) for guselkumab versus subcutaneous (SC) tumor necrosis factor inhibitors (TNFis)., Methods: Adults with PsA receiving guselkumab or their first SC TNFi (i.e., adalimumab, certolizumab pegol, etanercept, or golimumab) between 14 July 2020 and 31 March 2022 were identified in the IQVIA PharMetrics ® Plus database (first claim defined the treatment start date [index date]). Baseline characteristics and biologic use (biologic-naïve/biologic-experienced) were assessed during the 12-month period preceding the index date. Baseline characteristics were balanced between cohorts using propensity-score weighting based on the standardized mortality ratio approach. The follow-up period spanned from the index date until the earlier of the end of continuous insurance eligibility or end of data availability. On-label persistence, defined as the absence of treatment discontinuation (based on a gap of 112 days for guselkumab or 56 days for SC TNFi) or any dose escalation/reduction during follow-up, was assessed in the weighted treatment cohorts using Kaplan-Meier (KM) curves. A Cox proportional hazards model, further adjusted for baseline biologic use, was used to compare on-label persistence between the weighted cohorts., Results: The guselkumab cohort included 526 patients (mean age 49.8 years; 61.2% female) and the SC TNFi cohort included 1953 patients (mean age: 48.5 years; 60.2% female). After weighting, baseline characteristics were well balanced with a mean follow-up of 12.3-12.4 months across cohorts; 51.5% of patients in the guselkumab cohort and 16.7% in the SC TNFi cohort received biologics in the 12-month baseline period. Respective rates of treatment persistence at 3, 6, 9, and 12 months were 91.2%, 84.1%, 75.9%, and 71.5% for the guselkumab cohort versus 77.3%, 61.6%, 50.0%, and 43.7% for the SC TNFi cohort (all log-rank p < 0.001). At 12 months, patients in the guselkumab cohort were 3.0 times more likely than patients in the SC TNFi cohort to remain persistent on treatment (p < 0.001). Median time to discontinuation was not reached for the guselkumab cohort and was 8.9 months for the SC TNFi cohort., Conclusion: This real-world study employing US commercial health-plan claims data to assess on-label treatment persistence in PsA demonstrated that, at 12 months, guselkumab was associated with a 3 times greater likelihood of persistence compared with SC TNFi., (© 2024.

Objectives: Evaluate patterns of stringent disease control with 2 years of guselkumab across key disease-identified domains and patient-reported outcomes (PROs) in subgroups of patients with psoriatic arthritis (PsA) defined by baseline characteristics., Method: This post hoc analysis of DISCOVER-2 (Clinicaltrials.gov NCT03158285) evaluated biologic-naïve PsA patients (≥ 5 swollen/ ≥ 5 tender joints, C-reactive protein [CRP] ≥ 0.6 mg/dL) randomized to guselkumab every 4 weeks (Q4W); guselkumab at Weeks 0 and 4, then Q8W; or placebo with crossover to guselkumab Q4W at Week 24. Achievement of American College of Rheumatology 50/70% improvement (ACR50/70), Investigator's Global Assessment (IGA) 0, dactylitis/enthesitis resolution, Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue response (≥ 4-point improvement), HAQ-Disability Index (HAQ-DI) response (≥ 0.35-point improvement), PsA Disease Activity Score (PASDAS) low disease activity (LDA), and minimal disease activity (MDA) was assessed at Weeks 24, 52, and 100 in subgroups defined by sex and baseline medication use, body mass index, PsA duration, swollen/tender joints, CRP, and psoriasis severity/extent. Patients with missing categorical response data were considered nonresponders., Results: 442/493 (90%) guselkumab-randomized patients completed treatment through Week 100. Significant multi-domain efficacy of guselkumab versus placebo was shown across adequately sized patient subgroups. A pattern of continuous improvement was observed across key PsA domains and PROs within patient subgroups: 65%-85% of guselkumab-randomized patients had enthesitis/dactylitis resolution, 50%-70% achieved complete skin clearance, 60%-80% reported meaningful improvements in function/fatigue, 40%-65% achieved PASDAS LDA, and 35%-50% achieved MDA at Week 100., Conclusion: Patients with active PsA receiving guselkumab demonstrated durable achievement of stringent endpoints associated with disease control across key PsA domains and PROs, regardless of baseline characteristics. Key Points • Among biologic-naïve patients with highly active psoriatic arthritis (PsA), efficacy of guselkumab across stringent disease endpoints and patient-reported outcomes (PROs) at Week 24 was consistent regardless of baseline demographics and disease characteristics. • Within guselkumab-randomized PsA patient subgroups, major improvements in joint disease activity, complete skin clearance, dactylitis/enthesitis resolution, clinically meaningful improvements in PROs, and achievement of low overall disease activity were maintained through Week 100. • Durable stringent endpoint achievement indicating disease control was observed with guselkumab, regardless of baseline patient or disease characteristics., (© 2024.

Objective: We assessed and compared immunologic differences and associations with clinical response to guselkumab, a fully human interleukin (IL)-23p19 subunit inhibitor, in participants with active psoriatic arthritis (PsA) who were biologic-naive or had inadequate response to tumor necrosis factor inhibitors (TNFi-IR)., Methods: Serum biomarker levels at baseline and after treatment with guselkumab 100 mg every 8 weeks were compared between biologic-naive (n = 251) and TNFi-IR (n = 93) subgroups identified in the pooled DISCOVER-1/DISCOVER-2/COSMOS data set. Baseline biomarker levels determined by achievement of week 24 clinical responses (≥75%/90% improvement in Psoriasis Area and Severity Index [PASI 75/90], Investigator's Global Assessment [IGA] of psoriasis score 0/1 and ≥2-point improvement], ≥20% improvement in American College of Rheumatology criteria [ACR20]) were compared between prior treatment subgroups., Results: Baseline IL-22, TNFα, and beta defensin-2 (BD-2) levels were significantly lower in biologic-naive than in TNFi-IR participants. With guselkumab, week 24 IL-17A, IL-17F, IL-22, serum amyloid A, C-reactive protein, IL-6, and BD-2 levels were significantly reduced from baseline in biologic-naive and TNFi-IR participants (≥1.4-fold difference, nominal P < 0.05). Clinical responders to guselkumab exhibited significantly higher baseline levels of several biomarkers than nonresponders (IL-17A, IL-17F, BD-2 in biologic-naive PASI 90 responders; IL-17A, BD-2 in TNFi-IR IGA 0/1 responders; IL-22, BD-2 in TNFi-IR PASI 90 responders [nominal P < 0.05]) and trended higher in TNFi-IR ACR20 responders., Conclusion: Guselkumab modulates IL-23 signaling and provides consistent pharmacodynamic effects in both biologic-naive and TNFi-IR PsA patients. Significantly elevated baseline IL-22, TNFα, and BD-2 levels and associations between baseline IL-22, IL-17A, and BD-2 levels and skin responses to guselkumab suggest greater dysregulation of IL-23/Th17 signaling in patients with TNFi-IR., (© 2024 The Authors.

Background: Tumor necrosis factor inhibitors (TNFi) are frequently chosen as the first biologic for patients with psoriatic arthritis (PsA). Given that many patients with PsA are TNFi inadequate responders (TNF-IR; either inadequate efficacy or intolerance), treatments utilizing alternative mechanisms of action are needed. In phase 3 studies, the fully human interleukin (IL)-23p19 subunit-inhibitor, guselkumab, was efficacious in patients with active PsA, including TNFi-IR. Efficacy was generally consistent between TNFi-naïve and TNFi-experienced cohorts; however, in the latter, higher response rates have been observed with the Q4W dosing regimen relative to the Q8W dosing regimen for some endpoints, suggesting the need to evaluate whether more frequent dosing may provide an incremental clinical benefit for TNFi-IR patients., Methods: The phase 3b SOLSTICE study will assess guselkumab efficacy and safety in TNFi-IR PsA patients. Eligibility criteria include a PsA diagnosis for ≥ 6 months; active disease (≥ 3 swollen, ≥ 3 tender joints, C-reactive protein ≥ 0.3 mg/dL); and inadequate efficacy with, and/or intolerance to, one prior TNFi. Participants will be randomized 1:1:1 to guselkumab Q4W or Q8W or placebo→guselkumab Q4W (at Week 24). The primary endpoint is the proportion of patients achieving ≥ 20% improvement in the American College of Rheumatology criteria (ACR20) at Week 24. Major secondary endpoints include ACR50, ACR70; an Investigator's Global Assessment (IGA) of psoriasis score of 0/1 plus ≥ 2-grade reduction and ≥ 90% improvement in Psoriasis Area and Severity Index (both among patients with ≥ 3% body surface area affected by psoriasis and baseline IGA ≥ 2); minimal/very low disease activity; and changes from baseline in Health Assessment Questionnaire-Disability Index, the 36-item Short-Form Health Survey Physical Component Summary, and Functional Assessment of Chronic Illness Therapy-Fatigue scores. The target sample size (N = 450) is estimated to provide > 90% power in detecting differences between each guselkumab group and the placebo group for the primary endpoint assuming a 2-sided α = 0.05. Cochran-Mantel-Haenszel testing and analyses of covariance will be used to compare efficacy for binary and continuous endpoints, respectively., Discussion: Findings from the phase 3b SOLSTICE study, the design of which was informed by results from previously conducted phase 3 studies, is expected to provide important efficacy and safety information on guselkumab therapy in TNFi-IR patients with PsA., Trial Registration: This trial was registered at ClinicalTrials.gov, NCT04936308, on 23 June 2021., (© 2024. The Author(s).)

Objective: Evaluate patient-reported outcomes after 6 months of on-label guselkumab use in patients with rheumatologist-diagnosed active psoriatic arthritis (PsA) enrolled in the CorEvitas PsA/Spondyloarthritis Registry., Methods: This analysis includes registry participants who initiated and persisted with on-label guselkumab (after US Food and Drug Administration approval for PsA; 100 mg at weeks 0, 4, and every 8 weeks) at their 6-month follow-up visit (On-Label Persisters). Among patients not meeting response criteria at baseline, responses at 6 months were determined for patient-reported outcomes, including patient-reported pain (0-100 mm visual analog scale), patient global assessment of arthritis + psoriasis (PtGA; 0-100 visual analog scale), and Health Assessment Questionnaire-Disability Index (HAQ-DI; 0-3). Unadjusted, nominal P values were calculated via single-proportion, one-sided test (H 0 = 0%; α = 0.05)., Results: Of 90 On-Label Persisters, most had treatment-resistant PsA (92.2% and 73.3% previously received ≥1 and ≥2 biologic/targeted synthetic disease-modifying antirheumatic drugs, respectively), with mean (SD) baseline patient-reported pain, PtGA, and HAQ-DI scores of 57.0 (24.6), 50.3 (24.4), and 0.9 (0.6), respectively. Among those with patient-reported pain and PtGA scores of at least 15 at baseline, 40.2% (33/82) and 46.8% (36/77), respectively, achieved at least 15-mm reductions at 6 months; among those with HAQ-DI scores of at least 0.35 and more than 0.5 at baseline, respectively, 30.4% (21/69) achieved improvements of at least 0.35 and 10.3% (6/58) achieved scores of 0.5 or lower at 6 months (all nominal P < 0.001)., Conclusion: Pain and physical function are important contributors to health-related quality of life. In this real-world population of patients with treatment-resistant PsA and 6 months of persistent guselkumab treatment, clinically meaningful improvements in pain and physical function were achieved by approximately 40% and 30% of patients, respectively., (© 2024 The Authors.

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 β ≥ 0.5), without differences between instruments; longitudinal associations between swollen joint count (β ≤ 0.06)/LEI (β ≤ 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., Trial Registration: ClinicalTrials.gov, http://clinicaltrials.gov, NCT03162796 and NCT03158285., (© The Author(s) 2024.

Sjögren's disease (SjD) is a systemic autoimmune exocrinopathy with key features of dryness, pain, and fatigue. SjD can affect any organ system with a variety of presentations across individuals. This heterogeneity is one of the major barriers for developing effective disease modifying treatments. Defining core disease domains comprising both specific clinical features and incorporating the patient experience is a critical first step to define this complex disease. The OMERACT SjD Working Group held its first international collaborative hybrid meeting in 2023, applying the OMERACT 2.2 filter toward identification of core domains. We accomplished our first goal, a scoping literature review that was presented at the Special Interest Group held in May 2023. Building on the domains identified in the scoping review, we uniquely deployed multidisciplinary experts as part of our collaborative team to generate a provisional domain list that captures SjD heterogeneity., Competing Interests: Declaration of competing interest Valerie Devauchelle reports receinving funds for consulting to Novartis, Abbvie, Fresenius Kabi.

Background: To explore the trajectory of, and factors contributing to, achievement of individual criteria of minimal disease activity (MDA) in patients with active psoriatic arthritis (PsA) treated with guselkumab., Methods: The Phase 3, randomized, placebo-controlled DISCOVER-2 study enrolled adults (N = 739) with active PsA despite standard therapies who were biologic/Janus kinase inhibitor-naive. Patients were randomized 1:1:1 to guselkumab 100 mg every 4 weeks; guselkumab 100 mg at week 0, week 4, then every 8 weeks; or placebo. In this post hoc analysis, patients randomized to guselkumab were included and pooled (N = 493). Longitudinal trajectories of achieving each MDA criterion through week 100 were derived using non-responder imputation. Time to achieve each criterion was estimated with Kaplan-Meier analysis. Multivariate regression for time to achieve each criterion (Cox regression) and achievement at week 100 (logistic regression) was used to identify contributing factors., Results: Continuous improvement across all MDA domains was shown over time. ~70% of patients achieved near remission in swollen joint count (SJC), Psoriasis Area and Severity Index (PASI), and enthesitis through week 100. Median times to achieve individual criteria differed significantly (p < 0.0001), with SJC ≤ 1 (20 weeks), PASI ≤ 1 (16 weeks), and ≤ 1 tender entheses (16 weeks) being faster than patient-reported criteria (pain ≤ 15 mm, patient global assessment of arthritis and psoriasis ≤ 20 mm, Health Assessment Questionnaire-Disability Index ≤ 0.5) and tender joint count ≤ 1. Higher baseline domain scores, older age, worse fatigue, and increased body mass index were significant predictors of longer time to achieve minimal levels of disease activity assessed via patient-reported criteria., Conclusions: Substantial proportions of guselkumab-treated patients achieved individual MDA criteria, each showing continuous improvement through week 100, although with distinct trajectories. Median times to achieve physician-assessed MDA criteria were significantly faster compared with patient-driven criteria. Identification of modifiable factors affecting the time to achieve patient-reported criteria has the potential to optimize the achievement and sustainability of MDA in the clinic via a multidisciplinary approach to managing PsA, involving both medical and lifestyle interventions., Trial Registration Number: NCT03158285., Trial Registration Date: May 16, 2017., (© 2024.

Psoriatic arthritis (PsA) is a chronic inflammatory disease that often goes unrecognized in patients with psoriasis. As a result, patients may develop significant structural damage before diagnosis and initiation of adequate treatment. Dermatologists are in an unique position to identify early signs and symptoms of PsA. Here, we briefly review the pathogenesis of PsA, differences in PsA presentation within real-world dermatology practice versus rheumatology clinical trials, and imaging modalities that can be used to assess structural damage. We then discuss several ongoing controversies related to prediction, assessment, and treatment of PsA-related structural damage. Debated questions include the following: (1) Does subclinical enthesitis predict progression from psoriasis to PsA?, (2) Does methotrexate inhibit progression of structural damage?, (3) Does structural damage correlate with clinical disease activity?, and (4) Can progression from psoriasis to PsA be prevented? Evidence presented herein suggests that dermatologists, together with rheumatologists, can play important roles in the early diagnosis and treatment of PsA, thereby potentially preventing irreversible structural damage., Competing Interests: Conflicts of interest Dr Merola has served as consultant and/or investigator for AbbVie, Amgen, Biogen, Bristol Myers Squibb, Dermavant, Eli Lilly, Incyte, Janssen, Leo Pharma, Novartis, Pfizer, Sanofi, Regeneron, Sun Pharma, and UCB.

Introduction: The benefit/risk profiles of biologics can be affected by comorbidities, certain demographic characteristics, and concomitant medications; therefore, it is important to evaluate the long-term safety profiles of biologics across broad patient populations. Guselkumab was well tolerated and efficacious across individual pivotal clinical studies in adults with moderate-to-severe psoriasis and/or active psoriatic arthritis (PsA)., Objectives: The objective of the current analysis was to evaluate guselkumab safety in a large population of patients with psoriatic disease by pooling adverse event (AE) data from 11 phase II/III studies (seven in psoriasis; four in PsA)., Methods: Guselkumab was generally administered as 100 mg subcutaneous injections at Week 0, Week 4, then every 8 weeks (Q8W) in psoriasis studies and at Week 0, Week 4, then every 4 weeks (Q4W) or Q8W in PsA studies. Safety data were summarized for the placebo-controlled period (Weeks 0-16 in psoriasis; Weeks 0-24 in PsA) and through the end of the reporting period (up to 5 years in psoriasis; up to 2 years in PsA). Using the integrated data, incidence rates of key AEs were determined post hoc, adjusted for duration of follow-up, and reported per 100 patient-years (PYs). AE rates were also determined in subgroups of patients defined by sex, age, body mass index (BMI), and prior biologic use., Results: During the placebo-controlled period, 1061 patients received placebo (395 PYs) and 2257 received guselkumab (856 PYs). Through the end of the reporting period, 4399 guselkumab-treated patients contributed 10,787 PYs of follow-up. During the placebo-controlled period, in the guselkumab and placebo groups, respectively, rates of AEs were 281 versus 272/100 PYs, and infections were 76.0 versus 72.2/100 PYs. Rates of serious AEs (5.6 vs. 7.8/100 PYs), AEs leading to discontinuation (4.9 vs. 6.6/100 PYs), serious infections (1.0 vs. 2.3/100 PYs), malignancy (0.59 vs. 0.25 patients/100 PYs), and major adverse cardiovascular events (MACE; 0.35 vs. 0.25/100 PYs) were low and comparable between guselkumab and placebo. Among guselkumab-treated patients, safety event rates through the end of the reporting period were numerically lower than or comparable with rates observed during the placebo-controlled period: AEs, 164/100 PYs; infections, 61.2/100 PYs; serious AEs, 5.4/100 PYs; AEs leading to discontinuation, 1.8/100 PYs; serious infections, 1.0/100 PYs; malignancy, 0.6/100 PYs; and MACE, 0.3/100 PYs. No AEs of Crohn's disease, ulcerative colitis, or active tuberculosis were reported among guselkumab-treated patients. In the psoriasis studies, no opportunistic infections were reported among guselkumab-treated patients. Three AEs of opportunistic infections were reported in guselkumab-treated patients with PsA (0.14/100 PYs; all after Week 52 in DISCOVER-2). AE rates were largely consistent across subgroups of guselkumab-treated patients defined by sex, age, BMI, and prior biologic use., Conclusions: In this analysis of 4399 guselkumab-treated patients with psoriatic disease followed for 10,787 PYs, guselkumab had a favorable AE profile. AE rates were similar between guselkumab- and placebo-treated patients and were consistent throughout long-term guselkumab treatment and across broad subgroups of patients with psoriatic disease., Clinical Trials Registrations: Clinicaltrials.gov identifiers: NCT01483599, NCT02207231, NCT02207244, NCT02203032, NCT02905331, NCT03090100, NCT02325219, NCT02319759, NCT03162796, NCT03158285, and NCT03796858., (© 2023.

Objective: Assess relationship between earlier clinical improvement and radiographic progression (RP) over 2 years in guselkumab-treated patients with active psoriatic arthritis (PsA)., Method: Post hoc analyses combined data from DISCOVER-2 biologic-naïve adults with active PsA randomized to either guselkumab 100 mg every 4 weeks (Q4W) or guselkumab at W0, W4, then Q8W. Correlations (Spearman's coefficient) between baseline disease parameters and total PsA-modified van der Heijde-Sharp (vdH-S) score were examined. Repeated-measures mixed models, adjusted for known RP risk factors, assessed the relationship between Disease Activity Index in PsA (DAPSA) improvement, DAPSA improvement exceeding the median or the minimal clinically important difference (MCID), or DAPSA low disease activity (LDA) at W8 and RP rate, assessed by change from baseline in vdH-S score through W100., Results: Baseline age, PsA duration, CRP level, and swollen joint count, but not psoriasis duration/severity, weakly correlated with baseline vdH-S score. Elevated baseline CRP (parameter estimate [β] = 0.17-0.18, p < 0.03) and vdH-S score (β = 0.02, p < 0.0001) significantly associated with greater RP through W100. Greater improvement in DAPSA (β = -0.03, p = 0.0096), achievement of DAPSA improvement > median (least squares mean [LSM] difference: -0.66, p = 0.0405) or > MCID (-0.67, p = 0.0610), or DAPSA LDA (-1.44, p = 0.0151) by W8 with guselkumab significantly associated with less RP through W100. The effect of W8 DAPSA LDA on future RP was strengthened over time among achievers vs. non-achievers (LSM difference enhanced from -1.05 [p = 0.0267] at W52 to -1.84 [p = 0.0154] at W100)., Conclusions: In guselkumab-treated patients with active PsA, earlier improvement in joint symptoms significantly associated with lower RP rates through 2 years, indicating blockade of the IL-23 pathway may modify long-term disease course and prevent further joint damage. Key Points • Greater improvement in DAPSA at Week 8 of guselkumab treatment was significantly associated with less progression of structural joint damage at 2 years in patients with active psoriatic arthritis (PsA). • Early control of peripheral joint disease activity with blockade of the IL-23 pathway may modify long-term PsA trajectory and prevent further joint damage., (© 2023.

Introduction: Guselkumab previously showed greater improvements versus placebo in axial symptoms in patients with psoriatic arthritis (PsA) (assessed by Bath Ankylosing Spondylitis Disease Activity Index [BASDAI] and Ankylosing Spondylitis Disease Activity Score [ASDAS]), in post hoc analyses of the phase 3, placebo-controlled, randomized DISCOVER-1 and DISCOVER-2 studies. We now evaluate durability of response in axial-related outcomes through 2 years of DISCOVER-2., Methods: DISCOVER-2 biologic-naive adults with active PsA (≥ 5 tender/ ≥ 5 swollen joints, C-reactive protein ≥ 0.6 mg/dl) were randomized to guselkumab 100 mg every 4 weeks (Q4W) or at week 0, week 4, then Q8W, or placebo → guselkumab Q4W at week 24. Among patients with imaging-confirmed sacroiliitis (investigator-identified), axial symptoms were assessed through 2 years utilizing BASDAI, BASDAI Question #2 (spinal pain), modified BASDAI (mBASDAI; excludes Question #3 [peripheral joint pain]), and ASDAS. Mean changes in scores and proportions of patients achieving ≥ 50% improvement in BASDAI (BASDAI 50) and ASDAS responses, including major improvement (decrease ≥ 2.0), were determined through week 100. Treatment failure rules (through week 24) and nonresponder imputation of missing data (post-week 24) were utilized. Mean BASDAI component scores were assessed through week 100 (observed data). Exploratory analyses evaluated efficacy by sex and HLA-B*27 status., Results: Among 246 patients with PsA and imaging-confirmed sacroiliitis, guselkumab-treated patients had greater mean improvements in BASDAI, mBASDAI, spinal pain, and ASDAS scores, lower mean BASDAI component scores, and greater response rates in achieving BASDAI 50 and ASDAS major improvement vs. placebo at week 24. Differences from placebo were observed for guselkumab-treated patients in selected endpoints regardless of sex or HLA-B*27 status. At week 100, mean improvements were ~ 3 points for all BASDAI scores and 1.6-1.7 for ASDAS; 49-54% achieved BASDAI 50 and 39% achieved ASDAS major improvement at week 100., Conclusions: Guselkumab treatment provided durable and meaningful improvements in axial symptoms and disease activity in substantial proportions of patients with active PsA and imaging-confirmed sacroiliitis., Trial Registration: Clinicaltrials.gov NCT03158285., (© 2023.

Introduction: The aim of this work is to evaluate treatment persistence and clinical outcomes after 6 months of on-label guselkumab use in patients with rheumatologist-diagnosed active psoriatic arthritis (PsA) enrolled in the CorEvitas PsA/Spondyloarthritis Registry., Methods: Participants with PsA who initiated and persisted with on-label guselkumab use post-Food and Drug Administration (FDA) approval for active PsA (7/13/2020; subcutaneous 100 mg at weeks 0, 4, and every 8 weeks) at their 6-month follow-up visit (occurring through 3/31/2023) comprised the primary analysis population (On-Label Persisters). Hierarchical, multiplicity-controlled primary and secondary outcomes were mean (95% confidence interval) changes from baseline at 6 months in clinical Disease Activity Index for PsA (cDAPSA; primary), Physician Global Assessment (PGA) of arthritis and psoriasis (visual analog scale [VAS] 0-100), patient-reported pain (VAS 0-100), and percent body surface area with psoriasis (%BSA). Paired t tests determined changes that were statistically significantly different from 0 (α = 0.05)., Results: Among 114 patients who initiated on-label guselkumab and had eligible baseline and 6-month visits, 90 (78.9%) had persistent use. Among these On-Label Persisters at baseline, mean duration of PsA symptoms = 13.6 years; mean cDAPSA, PGA, and patient-reported pain = 22.0, 42.3, and 57.0, respectively; 94.4% had a history of psoriasis (mean BSA 7.6%); and 18.9% and 73.3%, respectively, previously received 1 or ≥ 2 biologic/targeted synthetic disease-modifying antirheumatic drugs. The mean change (improvement) in cDAPSA was - 5.4 (- 8.5, - 2.3; p < 0.001) at 6 months. Significant mean improvements in PGA (- 19.0 [- 24.2, - 13.8]), patient-reported pain (- 9.1 [- 14.4, - 3.8]), and %BSA (- 5.1 [- 7.6, - 2.7]) were also observed (all p < 0.001)., Conclusions: In this real-world PsA population, generally characterized by longstanding, treatment-resistant, active disease at baseline, persistent guselkumab use in nearly 80% of patients with on-label use was accompanied by significant improvements in joint and skin symptoms and patient-reported pain at 6 months. These registry data support results from randomized clinical trials demonstrating the efficacy of guselkumab in improving PsA signs and symptoms., Trial Registration: clinicaltrials.gov: NCT02530268., (© 2023. The Author(s).)

Introduction: The aim of this study was to evaluate guselkumab efficacy on regional psoriasis in a subset of psoriasis patients with a self-reported psoriatic arthritis (PsA) diagnosis., Methods: In the phase 3 VOYAGE-1 and -2 studies, at week (W)0, patients with moderate-to-severe psoriasis were randomized to guselkumab 100 mg, placebo → guselkumab 100 mg at W16 through W44, or adalimumab 80 mg then 40 mg at W1 through W48 (VOYAGE-1) or W24 (VOYAGE-2). Pooled efficacy outcomes, including scalp-specific Investigator's Global Assessment (ss-IGA), hands and/or feet Physician's Global Assessment (hf-PGA), fingernail PGA (f-PGA), Nail Psoriasis Area and Severity Index (NAPSI), and Dermatology Life Quality Index (DLQI), were compared (nominal p-values) through W24 in patients with self-reported PsA diagnosis. Response rates/percentage improvement from baseline were determined, employing treatment failure rules and non-response/no improvement data imputation., Results: A total of 76, 153, and 106 psoriasis patients with self-reported PsA were randomized to the placebo, guselkumab, or adalimumab groups, respectively; the baseline characteristics of patients in all three arms were comparable. At W16, a greater proportion of guselkumab- versus placebo-treated patients achieved ss-IGA 0/1 (80.6% vs. 22.7%, p < 0.001), hf-PGA 0/1 (68.9% vs. 14.8%, p < 0.001), f-PGA 0/1 (47.6% vs. 17.0%, p < 0.001), and DLQI 0/1 (45.6% vs. 2.7%, p < 0.001) responses; mean percentage NAPSI improvement was also greater with guselkumab (39.5% vs. 6.5%, p < 0.001). At W24, patients receiving guselkumab had higher ss-IGA 0/1 (77.5% vs. 58.5%, p = 0.003) and DLQI 0/1 (47.7% vs. 34.3%, p = 0.024) response rates versus those receiving adalimumab. Response rates/mean percentage improvements at W48 (VOYAGE-1) were numerically greater with guselkumab than adalimumab (e.g., NAPSI improvement: 75.6% vs. 60.9%)., Conclusions: Guselkumab-treated patients with psoriasis and self-reported PsA showed meaningful improvements in nail, scalp, and palmoplantar psoriasis., Trial Registration: VOYAGE-1 (ClinicalTrials.gov Identifier: NCT02207231) and VOYAGE-2 (ClinicalTrials.gov Identifier: NCT02207244)., (© 2023.

Background: Guselkumab is a selective interleukin (IL)-23 inhibitor targeting the IL-23p19 subunit. In the phase 3b COSMOS trial, guselkumab demonstrated efficacy in treating participants with active psoriatic arthritis (PsA) and inadequate response (IR; lack of efficacy or intolerance) to tumor necrosis factor inhibitors (TNFi)., Methods: Adults with active PsA (≥ 3 swollen joints,  ≥ 3 tender joints) and IR to one or two TNFi (TNFi-IR) were randomized 2:1 to guselkumab at Weeks 0, 4, then every 8 weeks (Q8W) or placebo➔guselkumab Q8W at Week 24 with possible early escape at Week 16. Levels of serum cytokines, including interferon ɣ (IFNɣ), IL-10, and tumor necrosis factor α (TNFα); T helper 17 (Th17) effector cytokines IL-17A, IL-17F, and IL-22; and acute phase proteins C-reactive protein (CRP), IL-6, and serum amyloid A (SAA), were assessed and compared with matched healthy controls; guselkumab pharmacodynamics through Week 24 were also assessed. Associations between baseline biomarker levels and 1) baseline disease activity (28-joint disease activity score using CRP [DAS28-CRP], psoriasis area and severity index [PASI], and % body surface area [BSA] affected by psoriasis) and 2) clinical response (including  ≥ 20% improvement in American College of Rheumatology criteria [ACR20] response) at Week 24 were assessed., Results: Baseline serum levels of IL-6, IL-10, IL-17A, IL-17F, IL-22, TNFα, and IFNɣ were significantly higher in COSMOS TNFi-IR participants than in matched healthy controls. Baseline IL-6, CRP, and SAA levels were associated with baseline DAS28-CRP. IL-17A and IL-17F levels were associated with baseline PASI score and psoriasis BSA. Baseline swollen or tender joint counts did not associate with baseline biomarker levels. At Week 24, significant decreases from baseline in CRP, SAA, IL-17A, IL-17F, and IL-22 levels were seen in guselkumab, but not placebo-, treated participants. IL-17F and IL-22 levels at Week 24 in guselkumab-treated participants did not significantly differ from those of matched healthy controls. Guselkumab-treated participants achieving ACR20 response at Week 24 exhibited higher baseline IL-22 and IFNɣ levels versus nonresponders., Conclusions: Results from COSMOS participants with active, TNFi-IR PsA suggest guselkumab reduces levels of effector cytokines associated with the IL-23/IL-17 pathway, including those associated with baseline arthritis and skin disease activity., Trial Registration: ClinicalTrials.gov: NCT03796858., (© 2023.

Background: This post-hoc analysis of PsABio (NCT02627768) evaluated safety, effectiveness and treatment persistence in patients < 60 and ≥ 60 years of age receiving ustekinumab over 3 years., Methods: Measures included adverse events (AE), clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) low disease activity (LDA) including remission, Psoriatic Arthritis Impact of Disease-12 (PsAID-12), Minimal Disease Activity, dactylitis, nail/skin involvement and time to treatment stop. Data were analysed descriptively., Results: Overall, 336 patients < 60 and 103 ≥ 60 years received ustekinumab, with a similar gender balance. A numerically lower proportion of younger patients reported at least one AE: 124/379 (32.7%) vs 47/115 (40.9%) for patients < 60 and ≥ 60 years, respectively. Serious AEs were low (< 10%) in both groups. At 6 months, the proportion of patients with cDAPSA LDA was 138/267 (51.7%) and 35/80 (43.8%) for patients < 60 and ≥ 60 years, respectively, with the effectiveness being maintained through 36 months. PsAID-12 mean scores reduced for both groups from a baseline mean of 5.73 and 5.61 for patients < 60 and ≥ 60 years, respectively, to 3.81 and 3.88, respectively, at 6 months, and 2.02 and 3.24, respectively, at 36 months. Regarding treatment persistence, 173/336 (51.5%) vs 47/103 (45.6%) patients < 60 and ≥ 60 years, respectively, stopped or switched treatment., Conclusion: Fewer AEs were observed over 3 years for younger versus older patients with PsA. There were no clinically meaningful treatment response differences. Persistence was numerically higher in the older age group., (© 2023. The Author(s).)

Introduction: Emerging evidence suggests psoriatic arthritis (PsA) with axial involvement (axPsA) and radiographic axial spondyloarthritis (r-axSpA) may possibly represent distinct disorders, with some differing clinical manifestations, genetic associations, and radiographic findings. Moreover, axPsA and r-axSpA may respond differently to therapies: guselkumab (interleukin [IL]-23p19 subunit inhibitor [i]) and ustekinumab (IL-12/23p40i) demonstrated improvements in axial symptoms in patients with PsA; however, neither risankizumab (IL-23p19i) nor ustekinumab demonstrated efficacy versus placebo in patients with r-axSpA. Current analyses aim to further understand potential molecular distinctions between axPsA and r-axSpA and examine the pharmacodynamic effects of guselkumab in patients with axPsA and those with PsA without axial involvement (non-axPsA)., Methods: Post hoc analyses utilized biomarker data from blood and serum samples collected from a subset of participants in phase 3 studies of ustekinumab in r-axSpA and guselkumab in PsA (DISCOVER-1 and DISCOVER-2). Participants with axPsA were identified by investigator-verified sacroiliitis (imaging-confirmed) and axial symptoms. HLA mapping, serum cytokine analysis, and whole-blood RNA sequencing were conducted., Results: Relative to r-axSpA, patients with axPsA had a lower prevalence of HLA-B27, HLA-C01, and HLA-C02 alleles and a higher prevalence of HLA-B13, HLA-B38, HLA-B57, HLA-C06, and HLA-C12 alleles. Compared with r-axSpA, patients with axPsA had elevated baseline levels of serum IL-17A and IL-17F cytokines, enrichment of IL-17 and IL-10 pathway-associated genes, and neutrophil gene markers. Across axPsA and non-axPsA cohorts, reductions in cytokine levels and normalization of pathway-associated gene expression with guselkumab treatment were comparable., Conclusion: The differences in HLA genetic associations, serum cytokines, and enrichment scores support the concept that axPsA and r-axSpA may be distinct disorders. The comparable pharmacodynamic effects of guselkumab on cytokine levels and pathway-associated genes observed in patients with axPsA and non-axPsA are consistent with demonstrated clinical improvements across PsA cohorts. These findings contribute to the understanding of potential genetic and molecular distinctions between axPsA and r-axSpA., Trial Registration: ClinicalTrials.gov identifiers, NCT03162796, NCT0315828, NCT02437162, and NCT02438787., (© 2023.

Objectives: To determine the individual impact of key manifestations of psoriatic arthritis (PsA) on quality of life (QoL), physical function, and work disability., Methods: Data from the Adelphi 2018 PsA Disease-Specific Programme, a multinational, cross-sectional study of PsA patients, were used. PsA manifestations included peripheral arthritis (number of joints affected), psoriasis (body surface area [BSA]), axial involvement (inflammatory back pain [IBP] and sacroiliitis) enthesitis, and dactylitis. General, and disease-specific QoL, physical function, and work disability were measured with EQ-5D-5L, PsAID-12, HAQ-DI, and WPAI, respectively. Multivariate regression adjusting for potential confounders evaluated the independent effect of PsA manifestations on each outcome., Results: Among the 2222 PsA patients analysed, 77.0% had active psoriasis and 64.4% had peripheral arthritis; 5.9%, 6.8%, 10.2%, and 3.6% had enthesitis, dactylitis, IBP, or sacroiliitis, respectively. Mean EQ VAS scores were significantly poorer in patients with vs. without enthesitis (59.9 vs. 75.6), dactylitis (63.6 vs. 75.4), and with greater peripheral joint involvement (none: 82.5; 1-2 affected joints: 74.1; 3-6 joints: 74.2; >6 joints: 65.0). Significantly worse mean PsAID-12 scores were associated with vs. without enthesitis (4.39 vs. 2.34) or dactylitis (4.30 vs. 2.32), and with greater peripheral joint involvement (none: 1.21; 1-2 joints: 2.36; 3-6 joints: 2.74; >6 joints: 3.92), and BSA (none: 1.49; >3-10%: 2.96; >10%: 3.43). Similar patterns were observed with HAQ-DI and WPAI scores., Conclusion: Most PsA manifestations were independently associated with worse general, and PsA-specific QoL, physical function, and work disability, highlighting the need for treatments targeting the full spectrum of PsA symptoms to lower the burden of disease., (Copyright © 2023 The Authors.

Objective: The IL-23 p19-subunit inhibitor guselkumab has been previously compared with other targeted therapies for PsA through network meta-analysis (NMA). The objective of this NMA update was to include new guselkumab COSMOS trial data, and two key comparators: the IL-23 inhibitor risankizumab and the Janus kinase (JAK) inhibitor upadacitinib., Material and Methods: A systematic literature review was conducted to identify randomized controlled trials up to February 2021. A hand-search identified newer agents up to July 2021. Bayesian NMAs were performed to compare treatments on ACR response, Psoriasis Area and Severity Index (PASI) response, modified van der Heijde-Sharp (vdH-S) score, and serious adverse events (SAEs)., Results: For ACR 20, guselkumab 100 mg every 8 weeks (Q8W) and every 4 weeks (Q4W) were comparable (i.e. overlap in credible intervals) to most other agents, including risankizumab, upadacitinib, subcutaneous TNF inhibitors and most IL-17A inhibitors. For PASI 90, guselkumab Q8W and Q4W were better than multiple agents, including subcutaneous TNF and JAK inhibitors. For vdH-S, guselkumab Q8W was similar to risankizumab, while guselkumab Q4W was better; both doses were comparable to most other agents. Most agents had comparable SAEs., Conclusions: Guselkumab demonstrates better skin efficacy than most other targeted PsA therapies, including upadacitinib. For vdH-S, both guselkumab doses are comparable to most treatments, with both doses ranking higher than most, including upadacitinib and risankizumab. Both guselkumab doses demonstrate comparable ACR responses to most other agents, including upadacitinib and risankizumab, and rank favourably in the network for SAEs., (© The Author(s) 2022.

Objective: Previous analyses of pooled DISCOVER-1 and DISCOVER-2 data through Week 24 showed significantly higher rates of dactylitis resolution in patients treated with guselkumab compared with placebo. Here, we investigate associations between dactylitis resolution and other outcomes through 1 year., Methods: Patients were randomized 1:1:1 to receive subcutaneous injections of guselkumab 100 mg at Week 0, Week 4, and then every 4 or 8 weeks, or placebo with crossover to guselkumab at Week 24. Independent assessors determined dactylitis severity score (DSS; 0-3/digit; total = 0-60). Dactylitis resolution (DSS = 0) (prespecified) and at least 20%, at least 50%, and at least 70% DSS improvement from baseline (post hoc) were determined through Week 52 (nonresponder imputation for treatment failure through Week 24 and for missing data through Week 52). ACR50, tender/swollen joints, low disease activity (LDA) as assessed by composite indices, and radiographic progression (DISCOVER-2 only) were assessed in patients with dactylitis versus without dactylitis resolution at Week 24 and Week 52., Results: Patients with dactylitis at baseline (473 of 1118) had more severe joint and skin disease than those without dactylitis (645 of 1118). At Week 52, approximately 75% of guselkumab-randomized patients with dactylitis at baseline had complete resolution; approximately 80% had at least 70% DSS improvement. Through Week 52, new-onset dactylitis (DSS ≥1) was uncommon among patients with a DSS of 0 at baseline. Guselkumab-randomized patients with dactylitis resolution were more likely to achieve ACR50, at least 50% reduction in tender and swollen joints, and LDA at Week 24 and Week 52 than those without resolution. At Week 52, patients with dactylitis resolution had numerically less radiographic progression from baseline (DISCOVER-2)., Conclusion: Through 1 year, approximately 75% of guselkumab-randomized patients had complete resolution of dactylitis; patients exhibiting resolution were more likely to achieve other important clinical outcomes. Given the high burden of dactylitis, resolution may be associated with better long-term patient outcomes., (© 2023 The Authors.

Objective: Evaluate relationship between radiographic progression and clinical outcomes in post hoc analyses of patients with psoriatic arthritis (PsA) receiving up to 2 years of guselkumab therapy in the phase 3, placebo-controlled, randomised trial, DISCOVER-2., Methods: Biologic-naïve adults with active PsA (≥5 swollen joints /≥5 tender joints ; C reactive protein ≥0.6 mg/dL) were randomised to guselkumab 100 mg every 4 weeks (Q4W); guselkumab 100 mg at week 0, week 4, then every 8 weeks (Q8W); or placebo→guselkumab 100 mg Q4W (week 24). Radiographs (hands/feet) at week 0, week 24, week 52 and week 100 were scored via PsA-modified van der Heijde-Sharp (vdH-S) methodology. In these post hoc analyses, mean changes in vdH-S scores were summarised according to achievement of American College of Rheumatology 20/50/70 response; low disease activity (LDA) defined by Disease Activity in Psoriatic Arthritis (DAPSA) ≤14 or Psoriatic ArthritiS Disease Activity Score (PASDAS) ≤3.2, or minimal/very low disease activity (MDA/VLDA); and normalised physical function (Health Assessment Questionnaire-Disability Index (HAQ-DI) ≤0.5). Response rates for achieving MDA/VLDA and each component were determined among patients with and without radiographic progression (change in total vdH-S score >0.5). No formal hypothesis testing was performed., Results: 664 of 739 treated patients in DISCOVER-2 continued study treatment at week 52 and were included in these analyses. Mean changes in vdH-S scores from weeks 0 to 100 among all patients in the Q4W and Q8W groups were 1.7 and 1.5, respectively. Among all guselkumab-randomised patients, those who achieved ACR20/50/70, DAPSA LDA, PASDAS LDA, MDA, VLDA and HAQ-DI ≤0.5 (normalised physical function) had smaller mean changes in vdH-S scores than did non-responders at week 52 (0.2-1.2 vs 1.7-4.1) and week 100 (0.3-1.2 vs 2.0-4.6). Relative to patients with radiographic progression, those without progression were more likely to achieve the MDA criteria related to swollen and tender joint counts, patient-reported pain and global assessment, and normalised physical function through week 100., Conclusion: In these post hoc analyses, the achievement of low levels of disease activity, including MDA, was associated with diminished rates of radiographic progression observed in patients receiving up to 2 years of guselkumab. Radiographic non-progressors were more likely to achieve patient-reported MDA criteria of minimal pain and normalised physical function compared with radiographic non-responders., Trial Registration Number: NCT03158285., Competing Interests: Competing interests: ABG has received honoraria as an advisory board member, non-promotional speaker or consultant for: Amgen, AnaptysBio, Avotres Therapeutics, Boehringer Ingelheim, Bristol Myers Squibb, Dermavant, Dice Therapeutics, Eli Lilly, Janssen, Novartis, Pfizer, Sanofi, Sun Pharma, UCB Pharma and Xbiotech (stock options for an RA project); research/educational grants from: AnaptysBio, Bristol Myers Squibb, Janssen, Novartis, Ortho Dermatologics, Sun Pharma and UCB Pharma; all funds go to the Icahn School of Medicine at Mount Sinai.

Objective: Although psoriatic arthritis (PsA) is equally present in men and women, sex may influence clinical manifestations and the impact of disease on patients' lives. This study assessed differences in clinical characteristics, disability, quality of life (QOL), and work productivity by sex in real-world practice., Methods: A cross-sectional survey of rheumatologists/dermatologists and their patients with PsA was conducted in France, Germany, Italy, Spain, the United Kingdom, and the United States between June and August 2018. Data collected included demographics, treatment use, clinical characteristics (tender joint count, swollen joint count, body surface area affected by psoriasis), QOL (EuroQoL 5-Dimension questionnaire [EQ-5D], Psoriatic Arthritis Impact of Disease [PsAID12]), disability (Health Assessment Questionnaire-Disability Index [HAQ-DI]), and work productivity (Work Productivity and Impairment Index [WPAI]). Outcomes were compared between men and women using parametric and nonparametric tests, as appropriate., Results: Of 2270 patients (mean age 48.6 [SD 13.3] yrs, mean disease duration 4.9 [SD 6.0] yrs), 1047 (46.1%) were women. Disease duration, disease presentation, and biologic use (mean 54.2%) were comparable between women and men. Women reported worse QOL (EQ-5D: 0.80 [SD 0.2] vs 0.82 [SD 0.2]; P = 0.02), greater disability (HAQ-DI: 0.56 [SD 0.6] vs 0.41 [SD 0.5]; P < 0.01) and work activity impairment (WPAI: 27.9% [SD 22.0] vs 24.6% [SD 22.4]; P < 0.01) than men. However, women had a lower burden of comorbidities (Charlson Comorbidity Index: 1.10 [SD 0.5] vs 1.15 [SD 0.6]; P < 0.01)., Conclusion: In patients with similar PsA disease activity and treatment, women experienced greater disease impact than men. This represents a significant consideration for the therapeutic management of PsA., (Copyright © 2023 by the Journal of Rheumatology.)

Objective: To describe psoriatic arthritis (PsA) flares and their effect on patient-reported outcomes (PROs)., Methods: Cross-sectional surveys of rheumatologists/dermatologists and their patients with PsA were conducted in France, Germany, Italy, Spain, the United Kingdom, and the United States, capturing data on physician-reported patient flare status, demographics, PsA severity, and clinical outcomes. Patient-completed surveys captured data on PROs: 5-level EuroQol 5-dimension, Work Productivity and Activity Impairment questionnaire, Health Assessment Questionnaire-Disability Index, and 12-item Psoriatic Arthritis Impact of Disease questionnaire. Patients were compared by flare status using parametric and nonparametric tests. Multivariate regression was used to identify flare associations. Multivariate logistic regression adjusted for patient demographics and physician specialty assessed the effect of flare status., Results: Among 2238 patients (586 from the US, 1652 from Europe) managed by 572 physicians, physician-reported flare was present for 168 patients (7.5%), and self-reported flare was present for 95 patients (10% of available data). Mean (SD) flare count over 12 months was 2.2 (4.9), lasting on average 16.4 (16.2) days. Flare status was linked to worse PROs. Patients who had not flared in the last 12 months or had never flared had a higher quality of life, lower overall work impairment, and a lower degree of disability compared with patients who were currently experiencing a flare (all; P < 0.01)., Conclusion: Actively experiencing a flare adversely affected QOL, disability, and work productivity. PsA flares should be routinely assessed and managed in clinical care., (Copyright © 2023 by the Journal of Rheumatology.)

Introduction: Psoriatic arthritis (PsA) is a complex, immune-mediated disease associated with skin psoriasis that, if left untreated, can lead to joint destruction. Up to 30% of patients with psoriasis progress to PsA. In most cases, psoriasis precedes synovio-entheseal inflammation by an average of 5-7 years, providing a unique opportunity for early and potentially preventive intervention in a susceptible and identifiable population. Guselkumab is an effective IL-23p19 inhibitor Food and Drug Administration (FDA-approved for treatment of moderate-to-severe psoriasis and PsA. The Preventing Arthritis in a Multicentre Psoriasis At-Risk cohort (PAMPA) study aims to evaluate the efficacy of guselkumab in preventing PsA and decreasing musculoskeletal power Doppler ultrasound (PDUS) abnormalities in a population of patients with psoriasis who are at-increased risk for PsA progression., Methods and Analysis: The PAMPA study is a multicentre, randomised, double-blind, placebo-controlled, interventional, preventive trial comparing PDUS involvement and conversion to PsA in patients with psoriasis at-increased risk for progression treated with guselkumab compared with non-biological standard of care. The study includes a screening period, a double-blind treatment period (24 weeks) and an open-label follow-up period (72 weeks). At baseline, 200 subjects will be randomised (1:1) to receive either guselkumab 100 mg (arm 1) or placebo switching to guselkumab 100 mg starting at week 24 (arm 2). Arm 3 will follow 150 at-risk psoriasis patients who decline biological therapy and randomisation. Changes from baseline in the PDUS score at week 24 and the difference in proportion of patients transitioning to PsA at 96 weeks will be examined as the coprimary endpoints., Ethics and Dissemination: Ethics approval for this study was granted by the coordinating centre's (NYU School of Medicine) Institutional Review Board (IRB). Each participating site received approval through their own IRBs.

Background: The monoclonal antibody guselkumab is the first selective inhibitor of the interleukin-23 p19 subunit approved to treat adults with moderate-to-severe plaque psoriasis and active psoriatic arthritis (PsA). Given its recent approval for active PsA, data describing patients with PsA initiating guselkumab outside of clinical trials are limited., Objective: This analysis describes characteristics of patients with rheumatologist-diagnosed PsA initiating guselkumab in the US-based, prospective, observational CorEvitas Psoriatic Arthritis/Spondyloarthritis Registry., Methods: Demographics, lifestyle/disease characteristics, comorbidities, prior treatment, and disease activity were summarized for patients with PsA initiating guselkumab from registry inception through 30 September, 2021., Results: Of 113 patients initiating guselkumab, the majority were female (63%), obese (67%), had psoriasis (89%), and initiated guselkumab as monotherapy (81%). Common comorbidities were hypertension (32%), depression (30%), and diabetes mellitus (26%). Mean tender (6.8) and swollen (2.0) joint counts, clinical Disease Activity Index for PsA score (19.1), and 57% of participants with ≥ 3% body surface area affected by psoriasis indicated moderate disease activity. Axial involvement was identified in 49% of patients. Median patient-reported pain and fatigue visual analog scale scores (0-100) were 60 and 59, respectively. Prior to guselkumab, 76% of patients had received two or more biologic disease-modifying antirheumatic drugs; the last therapy prior to guselkumab was a biologic disease-modifying antirheumatic drug in 81% of patients., Conclusions: Registry participants with PsA initiating guselkumab had active peripheral joint and skin disease, with substantial pain and fatigue; a considerable proportion had axial involvement. Future studies will evaluate the effectiveness of guselkumab in this population., (© 2022. The Author(s).)

Objective: To evaluate fatigue frequency and severity among patients with psoriatic arthritis (PsA) and assess the effect of fatigue severity on patient-reported outcome measures (PROMs) assessing quality of life, function, and work productivity., Methods: Data were derived from the Adelphi Disease Specific Programme, a cross-sectional survey conducted in 2018 in the United States and Europe. Patients had physician-confirmed PsA. Fatigue was collected as a binary variable and through its severity (0-10 scale, using the 12-item Psoriatic Arthritis Impact of Disease fatigue question) from patients; physicians also reported patient fatigue (yes/no). Other PROMs included the 5-level EuroQol 5-dimension questionnaire (EQ-5D-5L) for health-related quality of life (HRQOL), Health Assessment Questionnaire-Disability Index, and Work Productivity and Activity Impairment Questionnaire. Multivariate linear regression was used to evaluate the association between fatigue severity and other PROMs., Results: Among the 831 included patients (mean age 47.5 yrs, mean disease duration 5.3 yrs, 46.9% female, 48.1% receiving a biologic), fatigue was reported by 78.3% of patients. Patients with greater fatigue severity had greater disease duration, PsA severity, pain levels, body surface area affected by psoriasis, and swollen and tender joint counts (all P < 0.05). In multivariate analyses, patients with greater fatigue severity experienced worse physical functioning, HRQOL, and work productivity (all P < 0.001). Presence of fatigue was underreported by physicians (reported in only 32% of patients who self-reported fatigue)., Conclusion: Prevalence of patient-reported fatigue was high among patients with PsA and underrecognized by physicians. Fatigue severity was associated with altered physical functioning, work productivity, and HRQOL., (Copyright © 2022 by the Journal of Rheumatology.)

Background: Axial involvement constitutes a specific domain of psoriatic arthritis (PsA). Interleukin (IL)-23 inhibitors have demonstrated improvement in axial PsA (axPsA) symptoms, but have not shown efficacy in treating ankylosing spondylitis (AS), suggesting differences in axPsA processes and treatments. In a post hoc, pooled analysis of patients with investigator- and imaging-confirmed sacroiliitis in two phase 3, randomized, placebo-controlled studies (DISCOVER-1 and DISCOVER-2), patients treated with guselkumab, an IL-23p19 inhibitor, had greater axial symptom improvements compared with placebo. Confirmatory imaging at baseline was restricted to the sacroiliac (SI) joints, occurred prior to/at screening, and was locally read., Methods: The STAR study will prospectively assess efficacy outcomes in PsA patients with magnetic resonance imaging (MRI)-confirmed axial inflammation. Eligible, biologic-naïve patients with PsA (N =  405) for ≥ 6 months and active disease (≥ 3 swollen and ≥ 3 tender joints, C-reactive protein [CRP] ≥ 0.3 mg/dL) despite prior non-biologic disease-modifying antirheumatic drugs, apremilast, and/or nonsteroidal anti-inflammatory drugs will be randomized (1:1:1) to guselkumab every 4 weeks (Q4W); guselkumab at week (W) 0, W4, then every 8 weeks (Q8W); or placebo with crossover to guselkumab at W24, W28, then Q8W. Patients will have Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score ≥ 4, spinal pain component score (0-10 visual analog scale) ≥ 4, and screening MRI-confirmed axial involvement (positive spine and/or SI joints according to centrally read Spondyloarthritis Research Consortium of Canada [SPARCC] score ≥ 3 in ≥ 1 region). The primary endpoint is mean change from baseline in BASDAI at W24; multiplicity controlled secondary endpoints at W24 include AS Disease Activity Score employing CRP (ASDAS), Disease Activity Index for PsA (DAPSA), Health Assessment Questionnaire - Disability Index (HAQ-DI), Investigator's Global Assessment of skin disease (IGA), and mean changes from baseline in MRI SI joint SPARCC scores. Centrally read MRIs of spine and SI joints (scored using SPARCC) will be obtained at W0, W24, and W52, with readers blinded to treatment group and timepoint. Treatment group comparisons will be performed using a Cochran-Mantel-Haenszel or chi-square test for binary endpoints and analysis of covariance, mixed model for repeated measures, or constrained longitudinal data analysis for continuous endpoints., Discussion: This study will evaluate the ability of guselkumab to reduce both axial symptoms and inflammation in patients with active PsA., Trial Registration: This trial was registered at ClinicalTrials.gov, NCT04929210 , on 18 June 2021., Protocol Version: Version 1.0 dated 14 April 2021., (© 2022.

Infliximab and golimumab are intravenously (IV) administered tumor necrosis factor inhibitors approved to treat moderate-to-severe rheumatoid arthritis (RA) with concomitant methotrexate. Owing to differences in biologic construct, patients with IV-infliximab treatment failure may benefit from switching to IV-golimumab. Utilizing the ACR's Rheumatology Informatics System for Effectiveness (RISE), a large electronic health records registry based in the USA, we assessed RA disease activity in patients switching from IV-infliximab to IV-golimumab. This retrospective, longitudinal, single-arm study included adults (≥ 18 years) with ≥ 1 RA diagnosis code between 2014 and 2018 and ≥ 1 IV-infliximab prescription within 6 months of a new IV-golimumab order (index date). Longitudinal assessments of disease activity using the Clinical Disease Activity Index (CDAI) were calculated in patients continuing IV-golimumab for 6-9- and 9-12-months post-switch. Paired t-tests evaluated significance of mean improvements during the follow-up periods. Most RA patients with disease activity assessments during the 6-month follow-up (N = 100; mean age: 65.3 years; 81% female; 74% white) demonstrated moderate-to-high disease activity (CDAI: 73% [38/52]) at enrollment. On average, patients showed significant improvement in disease activity within 6-9 months of switching; mean CDAI scores improved from 21.3 to 14.1 (p < 0.0001) and were durable through 9-12 months of treatment. Real-world patients with moderate-to-high disease activity who switched from IV-infliximab to IV-golimumab demonstrated significant and sustained improvements post-switch as measured by the CDAI. Key Points • This study used real-world data from the Rheumatology Informatics System for Effectiveness (RISE) registry to evaluate the efficacy of directly switching from intravenous (IV)-infliximab to IV-golimumab to control rheumatoid arthritis (RA) disease activity. • Most IV-infliximab patients had moderate-to-high disease activity at the time of the switch. • On average, IV-golimumab was effective in improving RA disease activity after switching from IV-infliximab as measured by the Clinical Disease Activity Index. • These data suggest that real-world RA patients with persistent symptoms despite treatment with IV-infliximab may realize improved disease control with a switch to IV-golimumab., (© 2022.

Objective: Axial disease is common and burdensome in patients with psoriatic arthritis (PsA). Human leukocyte antigen-B27 (HLA-B27) is a risk factor for axial PsA; treatment response by HLA-B27 status is inadequately characterized. This study evaluated responses to biologic disease-modifying antirheumatic drugs (bDMARDs) or targeted synthetic DMARDs (tsDMARDs) overall and by HLA-B27 status in patients with PsA axial disease., Methods: This observational study included participants in the CorEvitas (formerly Corrona) PsA/Spondyloarthritis Registry who initiated bDMARD or tsDMARD treatment at baseline, had a 6-month follow-up visit, fulfilled Classification Criteria for Psoriatic Arthritis, had a baseline Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score of ≥4, and had known HLA-B27 status. Disease characteristics at baseline and 6 months were evaluated overall and by HLA-B27 status. Association between HLA-B27 status and treatment response was evaluated using an analysis of covariance model., Results: The analysis included 173 bDMARD or tsDMARD treatment initiations (54 [31.2%] among patients with HLA-B27+ status and 119 [68.8%] among patients with HLA-B27- status). BASDAI total and component scores decreased by ≤0.84 across groups after 6 months of bDMARD or tsDMARD therapy; these changes are not considered clinically meaningful. HLA-B27 status was not statistically significantly associated with changes in axial-related outcomes., Conclusion: In patients with PsA axial disease, 6 months of bDMARD or tsDMARD therapy provided only mild improvements in axial-related outcomes, irrespective of HLA-B27 status. This continued high disease activity reflects a critical unmet need for focus on the axial domain of PsA and for additional safe and effective therapies for psoriatic axial disease., (© 2022 The Authors.

Background: Intravenous (IV) golimumab, a TNFi, is approved for treating rheumatoid arthritis (RA), psoriatic arthritis (PsA), and ankylosing spondylitis (AS). We analyzed pooled safety results from three phase 3 IV golimumab trials in these rheumatologic diseases and hypothesized that the safety profile of IV golimumab would be similar to that established for other TNFi, including subcutaneous golimumab., Methods: Data from three double-blind, randomized trials of IV golimumab in patients with RA, PsA, and AS, each with a placebo-controlled period and an extension of active treatment, were included. Golimumab 2 mg/kg was administered at weeks 0 and 4, then every 8 weeks through week 100 (RA) or week 52 (PsA, AS). Concomitant low-dose, oral corticosteroids were permitted. Concomitant methotrexate was required in the RA trial and permitted in the PsA and AS trials; placebo patients crossed over to golimumab at weeks 24 (RA, PsA) and 16 (AS), respectively. Adverse events (AEs), including infections, serious infections, malignancies, and major adverse cardiovascular events (MACE), were assessed through week 112 (RA) or week 60 (PsA, AS)., Results: In total, 539 patients were randomized to placebo, and 740 patients were randomized to golimumab; 1248 patients received ≥ 1 golimumab administration. Among the placebo and golimumab patients, respectively, during the placebo-controlled periods, 40.6% and 50.3% had an AE, 2.4% and 3.8% had a serious AE, and 0.4% and 0.8% had a serious infection. Among all golimumab-treated patients, the numbers of events/100 patient-years (95% CI) were as follows: AEs, 175.2 (169.0, 181.6); serious AEs, 12.7 (11.0, 14.5); serious infections, 3.4 (2.5, 4.4); active tuberculosis, 0.4 (0.1, 0.8); opportunistic infection, 0.2 (0.1, 0.6); malignancies, 0.4 (0.2, 0.9), and MACE, 0.5 (0.2, 1.0). There were no cases of lymphoma. Three (0.6%) placebo-treated patients and 6 (0.5%) golimumab-treated patients died during the studies. Concomitant methotrexate was associated with increased occurrence of elevated alanine transaminase levels and lower incidence of antibodies to golimumab. During the placebo-controlled periods, serious infections in the placebo and golimumab groups were more common in patients receiving concomitant low-dose oral corticosteroids vs. those not receiving corticosteroids., Conclusions: IV golimumab demonstrated a safety profile that was broadly consistent across these rheumatologic indications and with other TNFi, including subcutaneous golimumab. Concomitant methotrexate or corticosteroids were associated with an increase in specific AEs., Trial Registrations: ClinicalTrials.gov , NCT00973479 .

Purpose: Golimumab is approved to treat moderate-to-severe active rheumatoid arthritis when given intravenously at weeks 0 and 4, then every 8 weeks (Q8W) with concomitant methotrexate. These analyses assessed whether a shorter dosing interval could ameliorate diminished efficacy experienced by a small proportion of patients toward the end of the dosing interval., Methods: Population pharmacokinetic and exposure-response modeling simulations were performed for intravenous golimumab 2 mg/kg at weeks 0 and 4, then Q8W or every 6 weeks (Q6W) through 1 year. A 2-compartment pharmacokinetic model with linear clearance developed based on GO-FURTHER (A Multicenter, Randomized, Double-blind, Placebo-controlled Trial of Golimumab, an Anti-TNFα Monoclonal Antibody, Administered Intravenously, in Patients With Active Rheumatoid Arthritis Despite Methotrexate Therapy) study data was used for pharmacokinetic simulations. A latent-variable indirect exposure-response model developed based on GO-FURTHER American College of Rheumatology (ACR) 20%/50%/70% improvement (ACR20, ACR50, and ACR70, respectively) data was used to predict clinical endpoints of ACR20/ACR50/ACR70 response rates., Findings: For Q6W and Q8W dosing, respectively, predicted median golimumab steady-state trough (C trough,ss ) concentrations were 0.57 and 0.24 µg/mL, and C max at steady state values were 33.1 and 32.9 µg/mL. Predicted peak median ACR20 steady-state response rates were 76.7% (Q6W) and 75.6% (Q8W). Predicted median ACR20 response rates at C trough,ss increased by 4.7 percentage points with Q6W (73.7%) versus Q8W (69.0%) dosing. Greater improvement in ACR20 response rates at trough time points was predicted in patients with lower golimumab trough serum concentrations. Consistent findings were observed for ACR50/ACR70 response rates., Implications: These simulations suggest that intravenous golimumab Q6W dosing increases golimumab C trough,ss , which may improve clinical response in the small proportion of patients with rheumatoid arthritis with waning efficacy at the end of the standard dosing interval., Clinicaltrials: gov identifier: NCT00973479.

Objective: To assess long-term efficacy and safety of guselkumab, an interleukin-23 p19 subunit (IL-23p19) inhibitor, in patients with active psoriatic arthritis (PsA) from the phase III DISCOVER-2 trial., Methods: In the DISCOVER-2 trial, patients with active PsA (≥5 swollen joints and ≥5 tender joints; C-reactive protein level ≥0.6 mg/dl) despite prior nonbiologic therapy were randomized to receive the following: guselkumab 100 mg every 4 weeks; guselkumab 100 mg at weeks 0 and 4 and then every 8 weeks; or placebo with crossover to guselkumab 100 mg every 4 weeks, beginning at week 24. Efficacy assessments included American College of Rheumatology ≥20%/50%/70% improvement criteria (ACR20/50/70), Investigator's Global Assessment (IGA) of psoriasis score of 0 (indicating complete skin clearance), resolution of enthesitis (Leeds Enthesitis Index) and dactylitis (Dactylitis Severity Score), and changes in the Sharp/van der Heijde modified radiographic scores for PsA. Clinical data (imputed as no response/no change from baseline if missing) and observed radiographic data were summarized through week 100; safety assessments continued through week 112., Results: Of the 739 randomized and treated patients, 652 (88%) completed treatment through week 100. Across groups of guselkumab-treated patients (including those in the placebo-guselkumab crossover group), the following findings at week 100 indicated that amelioration of arthritis signs/symptoms and extraarticular manifestations was durable through 2 years: ACR20 response (68-76%), ACR50 response (48-56%), ACR70 response (30-36%), IGA score of 0 (55-67%), enthesitis resolution (62-70%), and dactylitis resolution (72-83%). Mean changes in the Sharp/van der Heijde modified score for PsA from weeks 52 to week 100 (range 0.13-0.75) indicated that the low rates of radiographic progression observed among guselkumab-treated patients at earlier time points extended through week 100. Through week 112, 8% (5.8 per 100 patient-years) and 3% (1.9 per 100 patient-years) of the 731 guselkumab-treated patients had a serious adverse event or serious infection, respectively; 1 death occurred (road traffic accident)., Conclusion: In biologic-naive PsA patients, guselkumab provided durable improvements in multiple disease domains with no unexpected safety findings through 2 years., (© 2021 The Authors.

Objectives: To evaluate the efficacy through 52 weeks of guselkumab, an interleukin 23-p19 subunit inhibitor, in subgroups of pooled psoriatic arthritis (PsA) patients from the DISCOVER-1 and DISCOVER-2 trials defined by baseline patient characteristics., Methods: Adults with active PsA despite standard therapies were enrolled in DISCOVER-1 (≥3 swollen and ≥3 tender joints, C reactive protein (CRP) level ≥0.3 mg/dL) and DISCOVER-2 (≥5 swollen and ≥5 tender joints, CRP ≥0.6 mg/dL, biological-naïve). Randomised patients received 100 mg guselkumab at weeks 0, 4, and then every 4 or 8 weeks (Q4W/Q8W) or placebo. Guselkumab effects on joint (ACR20/50/70), skin (IGA 0/1, IGA 0), patient-reported outcome (Health Assessment Questionnaire Disability Index/Functional Assessment of Chronic Illness Therapy-Fatigue) and disease severity (minimal disease activity/PsA Disease Activity Score low disease activity) endpoints were evaluated by patient sex, body mass index, PsA duration, swollen/tender joint counts, CRP level, percent body surface area with psoriasis, Psoriasis Area and Severity Index score, and conventional synthetic disease-modifying antirheumatic drug use at baseline., Results: Baseline patients characteristics in DISCOVER-1 (N=381) and DISCOVER-2 (N=739) were well balanced across randomised groups. At week 24, 62% (232/373) and 60% (225/375), respectively, of guselkumab Q4W-treated and Q8W-treated patients pooled across DISCOVER-1 and DISCOVER-2 achieved the primary endpoint of ACR20 response versus 29% (109/372) of placebo-treated patients. Guselkumab treatment effect at week 24 was observed across patient subgroups. Within each patient subgroup, response rates across all disease domains were sustained or increased at week 52 with both guselkumab regimens., Conclusions: Guselkumab Q4W and Q8W resulted in robust and sustained improvements in PsA signs and symptoms consistently in subgroups of patients defined by diverse baseline characteristics., Trial Registration Numbers: NCT03162796, NCT03158285., Competing Interests: Competing interests: CTR has received consulting fees from AbbVie, Amgen, Bristol Myers Squibb, Janssen, Lilly, MoonLake, Novartis, Pfizer and UCB Pharma; and speaker fees from Novartis, Pfizer and UCB Pharma.

Introduction: Guselkumab is approved for the treatment of both moderate-to-severe plaque psoriasis and active psoriatic arthritis (PsA) in the USA. However, little is known about patients initiating guselkumab in a real-world setting. The objective of this study was to describe baseline characteristics among patients with plaque psoriasis who initiated guselkumab at or after enrollment in CorEvitas' Psoriasis Registry., Methods: Adult patients who initiated guselkumab in the Psoriasis Registry between July 18, 2017 and November 6, 2018 were included. Demographics, disease characteristics, and patient-reported outcome measures (PROMs) were assessed at the time of guselkumab initiation (baseline). Patients with psoriasis were stratified according to the number of previously received biologics (0 to 4+) for comparison. A subset of patients with psoriasis and concomitant dermatologist-diagnosed PsA were stratified into biologic-naïve and biologic-experienced groups., Results: Among 687 patients with psoriasis who initiated guselkumab, biologic-naïve patients and those with four or more prior biologics had the most severe disease and the worst PROM scores at baseline. Among 251 patients with concomitant dermatologist-diagnosed PsA, biologic-naïve patients had more severe disease and worse PROM scores than biologic-experienced patients., Conclusions: These findings highlight important differences in baseline characteristics according to biologic experience among patients with plaque psoriasis with or without concomitant PsA initiating guselkumab in a real-world setting., (© 2021.

Objectives: To compare work absenteeism and short-term disability among adults with psoriasis or psoriatic arthritis (PsA), versus controls in the USA., Methods: Adults eligible for work absenteeism and/or short-term disability benefits between 1/1/2009 and 4/30/2020 were screened in the IBM® MarketScan® Commercial and Health and Productivity Management Databases. The following groups were defined: (1) psoriasis: ≥ 2 psoriasis diagnoses ≥ 30 days apart and no PsA diagnoses; (2) PsA: ≥ 2 PsA diagnoses ≥ 30 days apart; (3) control: absence of psoriasis and PsA diagnoses. Controls were matched to psoriasis and PsA patients based on age, gender, index year, and comorbidities. Non-recreational work absences and sick leaves were evaluated in absentee-eligible patients, and short-term disability was evaluated in short-term disability-eligible patients. Costs (in 2019 USD) associated with each type of work absence were evaluated., Results: 4261 psoriasis and 616 PsA absentee-eligible and 25,213 psoriasis and 3480 PsA short-term disability-eligible patients were matched to controls. Average non-recreational work absence costs were $1681, $1657, and $1217 for the PsA, psoriasis, and control group, respectively. Compared with psoriasis patients and controls, more PsA patients had sick leaves after 1 year (56.2% versus 55.6% and 41.5%, p < 0.0001). Similarly, short-term disability was more frequent in PsA patients than psoriasis patients and controls at year one (8.8% versus 5.6% and 4.7%, p < 0.0001) and corresponding costs were higher ($605, $406, and $335 on average, p < 0.0001)., Conclusion: Annual work absenteeism and short-term disability were consistently greater among patients with PsA and psoriasis than controls, highlighting the substantial economic burden of psoriatic disease. Key points • Patients with PsA had greater short-term disability compared with patients with psoriasis and patients with neither psoriasis nor PsA. • Patients with PsA and patients with psoriasis incurred greater non-recreational work absences and sick leaves than patients with neither psoriasis nor PsA., (© 2021.

Objective: Evaluate tolerability and effectiveness of golimumab-IV versus infliximab in patients with rheumatoid arthritis (RA) in a real-world setting., Methods: AWARE, a prospective, real-world, pragmatic, observational, multicenter, phase 4 study, enrolled RA patients when initiating golimumab-IV or infliximab. Treatment decisions were made by the treating rheumatologist. The approved doses for RA are 2 mg/kg at weeks 0, 4, then Q8W for golimumab-IV and 3 mg/kg at weeks 0, 2, 6, then Q8W (dose escalation permitted) for infliximab. A prespecified formal interim analysis was conducted. The primary endpoint was the incidence of infusion reactions (any adverse event that occurred during or within 1 h of infusion) through week 52. Major secondary endpoints were mean change from baseline in CDAI at months 6 and 12 in biologic-naïve patients (non-inferiority margin in the CDAI = 6). Baseline characteristics were adjusted using propensity scores with inverse probability of treatment weights (IPTW)., Results: In the formal interim analysis (golimumab-IV, n = 479; infliximab, n = 354), the incidence of infusion reactions was significantly lower with golimumab-IV vs. infliximab (3.6 vs. 17.6%, p < 0.001, IPTW-adjusted). Among biologic-naïve patients, mean changes from baseline in CDAI at month 6 (- 9.5 golimumab-IV vs. - 10.1 infliximab) and at month 12 (- 9.4 golimumab-IV vs. - 10.1 infliximab) demonstrated non-inferiority., Conclusions: The proportion of patients with an infusion reaction was significantly lower with golimumab-IV vs. infliximab. Among biologic-naïve patients, mean change from baseline in CDAI at months 6 and 12 was non-inferior for golimumab-IV vs. infliximab. Compared with fixed-dose golimumab-IV, infliximab dose escalation did not provide any greater improvements in CDAI for patients with RA., Trial Registration: ClinicalTrials.gov identifier, NCT02728934., (© 2021.

Background: Guselkumab was efficacious in reducing signs and symptoms of psoriatic arthritis in the phase 3 DISCOVER-1 and DISCOVER-2 studies. We aimed to evaluate the efficacy of guselkumab in post-hoc analyses of patients with psoriatic arthritis with imaging-confirmed sacroiliitis consistent with axial involvement., Methods: In DISCOVER-1, 381 patients with active psoriatic arthritis (defined as ≥3 swollen joints, ≥3 tender joints, and C-reactive protein [CRP] ≥0·3 mg/dL) and in DISCOVER-2, 739 patients with active psoriatic arthritis (defined as ≥5 swollen joints, ≥5 tender joints, and CRP ≥0·6 mg/dL) were randomly allocated to receive guselkumab 100 mg every 4 weeks, guselkumab 100 mg every 8 weeks (week 0, week 4, then every 8 weeks), or placebo. These pooled, post-hoc analyses included patients with axial disease documented by previous imaging or pelvic radiography at screening consistent with sacroiliitis (confirmed by investigator). Efficacy assessments included least squares mean changes, with 95% CIs, in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score, modified BASDAI (mBASDAI; excluding peripheral joint pain), spinal pain, and Ankylosing Spondylitis Disease Activity Score (ASDAS), and proportions of patients achieving at least a 50% improvement in BASDAI score (BASDAI50) and achieving ASDAS responses of inactive disease (score <1·3), major improvement (change of ≥2·0), and clinically important improvement (change of ≥1·1)., Findings: Of the 1120 patients in the two DISCOVER studies, 312 (28%) were included in this analysis, of whom 118 were in the placebo group, 103 were in the guselkumab every 4 weeks group, and 91 were in the guselkumab every 8 weeks group. 191 (61%) were male, and 121 (39%) were female, and the mean age was 45·1 (SD 11·2). HLA-B27 status was assessed in 190 patients; 57 (30%) were HLA-B27-positive and 133 (70%) were HLA-B27-negative. At week 24, least squares mean changes from baseline in BASDAI were -2·7 (95% CI -3·2 to -2·2) in both guselkumab groups versus -1·3 (-1·8 to -0·9) in the placebo group; similar results were observed for mBASDAI and spinal pain. Least squares mean changes in ASDAS scores at week 24 were -1·4 (95% CI -1·7 to -1·2) in both guselkumab groups and -0·7 (-0·9 to -0·5) for placebo. At week 24, 36 (38%) patients in the guselkumab every 4 weeks group and 34 (40%) of those in the guselkumab every 8 weeks group achieved BASDAI50 versus 21 (19%) of placebo patients; greater proportions of guselkumab-treated patients achieved ASDAS responses versus placebo. Across outcomes, separation from placebo was observed at week 8. Improvements with guselkumab were seen at week 24 independent of HLA-B27 status. These improvements were maintained at week 52 in the guselkumab groups., Interpretation: Patients with active psoriatic arthritis and imaging-confirmed sacroiliitis who were treated with guselkumab every 4 weeks or every 8 weeks had greater mean improvements in BASDAI and ASDAS (as early as week 8) than did placebo-treated participants, with sustained improvements at week 52., Funding: Janssen Research & Development LLC., Competing Interests: Declaration of interests PJM reports grants and personal fees from AbbVie, Amgen, Bristol Myers Squibb, Eli Lilly, Galapagos, Gilead, Janssen, Novartis, Pfizer, SUN, and UCB, and personal fees from Boehringer Ingelheim and GlaxoSmithKline.

Objectives: To compare healthcare resource utilization and costs among patients with psoriasis, psoriatic arthritis (PsA), and a control group of patients without psoriasis and PsA in the USA., Methods: The IBM® MarketScan® Commercial Database was used to identify three adult patient groups from 1/1/2009 through 4/30/2020: (1) Psoriasis: ≥ 2 diagnoses ≥ 30 days apart for psoriasis (no PsA diagnoses); (2) PsA: ≥ 2 diagnoses for PsA; (3) Control: no psoriasis or PsA diagnoses in their entire claims records. Patients with comorbid rheumatoid arthritis, ankylosing spondylitis, Crohn's disease, or ulcerative colitis were excluded from the analyses. Controls were matched 1:1 to psoriasis and PsA patients based on age, gender, index year, and number of non-rheumatological comorbidities. Healthcare resource utilization and costs (in 2019 USD) were evaluated descriptively and through mixed models for five years of follow-up., Results: A total of 142,531 psoriasis and 21,428 PsA patients were matched to the control group (N = 163,959). Annual all-cause healthcare costs per patient were $7,470, $11,062, and $29,742 for the control, psoriasis, and PsA groups, respectively. All-cause healthcare costs increased over time and were significantly greater among PsA vs. psoriasis (p < 0.0001) and the control groups (p < 0.0001). Across all categories of healthcare resources, utilization was greatest among patients with PsA and lowest in the control group., Conclusion: Annual healthcare costs and resource utilization were significantly higher with PsA compared with psoriasis and the control group, confirming the substantial economic burden of PsA. The cost disparity between these patient groups highlights a continued unmet medical need. Key Points • Patients with PsA incurred significantly greater healthcare resource utilization and costs than patients with psoriasis and patients without psoriasis and PsA. • Significantly greater costs and healthcare resource utilization were also observed among patients with psoriasis compared with patients without psoriasis and PsA., (© 2021.

Introduction/objectives: To evaluate changes in health-related quality of life (HRQoL) and productivity following treatment with intravenous (IV) golimumab in patients with psoriatic arthritis (PsA)., Methods: Patients were randomized to IV golimumab 2 mg/kg (n=241) at Weeks 0, 4, then every 8 weeks (q8w) through Week 52 or placebo (n=239) at Weeks 0, 4, then q8w, with crossover to IV golimumab 2 mg/kg at Weeks 24, 28, then q8w through Week 52. Change from baseline in EuroQol-5 dimension-5 level (EQ-5D-5L) index and visual analog scale (EQ-VAS), daily productivity VAS, and the Work Limitations Questionnaire (WLQ) was assessed. Relationships between these outcomes and disease activity and patient functional capability were evaluated post hoc., Results: At Week 8, change from baseline in EQ-5D-5L index (0.14 vs 0.04), EQ-VAS (17.16 vs 3.69), daily productivity VAS (-2.91 vs -0.71), and WLQ productivity loss score (-2.92 vs -0.78) was greater in the golimumab group versus the placebo group, respectively. At Week 52, change from baseline was similar in the golimumab and placebo-crossover groups (EQ-5D-5L index: 0.17 and 0.15; EQ-VAS: 21.61 and 20.84; daily productivity VAS: -2.89 and -3.31; WLQ productivity loss: -4.49 and -3.28, respectively). HRQoL and productivity were generally associated with disease activity and functional capability, with continued association from Week 8 through Week 52., Conclusion: IV golimumab resulted in early and sustained improvements in HRQoL and productivity from Week 8 through 1 year in patients with PsA. HRQoL and productivity improvements were associated with improvements in disease activity and patient functional capability. Key Points • In patients with active psoriatic arthritis (PsA), intravenous (IV) golimumab improved health-related quality of life (HRQoL) and productivity as early as 8 weeks and maintained improvement through 1 year • Improvements in HRQoL and productivity outcomes in patients with PsA treated with IV golimumab were associated with improvements in disease activity and patient functional capability outcomes • IV golimumab is an effective treatment option for PsA that can mitigate the negative effects of the disease on HRQoL and productivity., (© 2021.

Objective: The efficacy of the novel interleukin (IL)-23p19 inhibitor guselkumab for psoriatic arthritis (PsA) has recently been demonstrated in two phase 3 trials (DISCOVER-1 & -2) but has not been evaluated vs other targeted therapies for PsA. The objective was to compare guselkumab to targeted therapies for PsA for safety and joint and skin efficacy through network meta-analysis (NMA)., Methods: A systematic literature review was conducted in January 2020 to identify randomized controlled trials. Bayesian NMAs were performed to compare treatments on American College of Rheumatology (ACR) 20/50/70 response, mean change from baseline in van der Heijde-Sharp (vdH-S) score, Psoriasis Area Severity Index (PASI) 75/90/100 response, adverse events (AEs) and serious adverse events (SAEs)., Results: Twenty-six phase 3 studies evaluating 13 targeted therapies for PsA were included. For ACR 20 response, guselkumab 100 mg every 8 weeks (Q8W) was comparable to IL-17A inhibitors and subcutaneous tumor necrosis factor (TNF) inhibitors. Similar findings were observed for ACR 50 and 70. For vdH-S score, guselkumab Q8W was comparable to other agents except intravenous TNF therapies. Results for PASI 75 and PASI 90 response suggested guselkumab Q8W was better than most other agents. For PASI 100, guselkumab Q8W was comparable to other active agents. For AEs and SAEs, guselkumab Q8W ranked highly but comparative conclusions were uncertain. Similar results were observed for all outcomes for guselkumab 100 mg every four weeks., Conclusions: In this NMA, guselkumab demonstrated favorable arthritis efficacy comparable to IL-17A and subcutaneous TNF inhibitors while offering better PASI response relative to many other treatments., (© The Author(s) 2021.
