Impact of Disease Factors of Patients with Psoriasis and Psoriatic Arthritis on Biologic Therapy Switching: Real-World Evidence from the CorEvitas Psoriasis Registry.

INTRODUCTION: Patients with psoriasis (PSO) and psoriatic arthritis (PsA) may frequently switch biologic therapies over the course of treatment because of symptom variability and individual responses. Real-world studies analyzing patient characteristics and clinical factors associated with biologic switching are limited. METHODS: This longitudinal cohort study used real-world data from the CorEvitas Psoriasis Registry to evaluate the relationship between associated disease factors and biologic switching among patients with PSO and PsA in the United States (US) and Canada following initiation of a biologic. Patients were evaluated between April 2015-August 2022. Combinations of disease severity (as measured by Psoriasis Area Severity Index [PASI]) and Dermatology Life Quality Index (DLQI) as a measure of health-related quality of life (HRQoL) were assessed, and the association with time to switching was calculated using Cox proportional hazards regression modeling. RESULTS: Among 2580 patient-initiations (instances of patients initiating a biologic), 504 (19.5%) switched biologics within 30 months of initiation. Switching was more frequent when either PASI > 10 or DLQI > 5 compared with PASI ≤ 10 or DLQI ≤ 5 at follow-up. Patients with higher skin involvement (PASI > 10) and impact on HRQoL (DLQI > 5) were 14 times more likely to switch (hazard ratio = 14.2, 95% confidence interval: 10.7, 18.9) than those with lower skin involvement (PASI ≤ 10) and HRQoL (DLQI ≤ 5). CONCLUSIONS: Patients with PSO and PsA treated in a real-world dermatology setting with substantial disease factors following biologic initiation were more likely to switch therapies. Those with PASI > 10 and DLQI > 5 switched more frequently than those with PASI ≤ 10 and DLQI ≤ 5.

Many patients with psoriasis may also have a related condition called psoriatic arthritis. Biologic medications work by helping to reduce inflammation and are commonly used to treat the symptoms of psoriasis and psoriatic arthritis. Patients might not all respond the same way to treatment and may need to change their medications over time. It is important we understand the reasons for switching medications to help patients better manage their symptoms.This study used information from a database on patients with both psoriasis and psoriatic arthritis. The database includes information on patients' medical history, including when they start and change their medication. We looked at data from patients who switched medications and patients who did not switch medications and examined differences in both how serious a doctor found their disease and the patients' own opinions of their overall health.We found that patients were more likely to change their biologic medication if they had more difficult psoriasis and psoriatic arthritis symptoms that caused worse skin problems, joint pain, and effects on their overall health compared with patients who had not changed their medication. These results suggest that it is important to consider both how serious a doctor finds their disease and patients' opinions of how much their symptoms affect their overall health. Understanding the reasons why patients switch medications will help to develop better ways of managing psoriasis and psoriatic arthritis.

Comparative Effectiveness of Bimekizumab and Ustekinumab in Patients with Psoriatic Arthritis at 52 Weeks Assessed Using a Matching-Adjusted Indirect Comparison.

INTRODUCTION: A matching-adjusted indirect comparison (MAIC) was conducted to assess the relative efficacy at 52 weeks (Wk52) of bimekizumab 160 mg every 4 weeks (Q4W) and ustekinumab 45 or 90 mg every 12 weeks (Q12W) in patients with psoriatic arthritis (PsA) who were biologic disease-modifying anti-rheumatic drug naïve (bDMARD naïve) or who had a previous inadequate response or an intolerance to tumor necrosis factor inhibitors (TNFi-IR). METHODS: Relevant trials were systematically identified. Individual patient data from the bimekizumab trials BE OPTIMAL (NCT03895203; N = 431) and BE COMPLETE (NCT03896581; N = 267) were matched with summary data on patients receiving ustekinumab in the PSUMMIT 1 trial (NCT01009086; 45 mg, N = 205; 90 mg; N = 204) and a subgroup of TNFi-IR patients receiving ustekinumab in the PSUMMIT 2 trial (NCT01077362; 45 mg, N = 60; 90 mg, N = 58), respectively. Patients from the bimekizumab trials were re-weighted using propensity scores to match the baseline characteristics of the ustekinumab trial patients. Adjustment variables were selected based on expert consensus (n = 5) and adherence to established MAIC guidelines. Non-placebo-adjusted comparisons of recalculated bimekizumab and ustekinumab outcomes for the American College of Rheumatology (ACR) 20/50/70 response criteria (non-responder imputation) were analyzed. RESULTS: In patients who were bDMARD naïve, bimekizumab had a greater likelihood of response than ustekinumab at Wk52 for ACR20 (odds ratio [95% confidence interval] 45 mg: 2.14 [1.35, 3.40]; 90 mg: 1.98 [1.24, 3.16]), ACR50 (45 mg: 2.74 [1.75, 4.29]; 90 mg: 2.29 [1.48, 3.55]), and ACR70 (45 mg: 3.33 [2.04, 5.46]; 90 mg: 3.05 [1.89, 4.91]). In patients who were TNFi-IR, bimekizumab had a greater likelihood of response than ustekinumab at Wk52 for ACR20 (45 mg: 4.17 [2.13, 8.16]; 90 mg: 4.19 [2.07, 8.49]), ACR50 (45 mg: 5.00 [2.26, 11.05]; 90 mg: 3.86 [1.70, 8.79]), and ACR70 (45 mg: 9.85 [2.79, 34.79]; 90 mg: 6.29 [1.98, 20.04]). CONCLUSIONS: Using MAIC, bimekizumab showed greater efficacy than ustekinumab in achieving all ACR responses in patients with PsA who were bDMARD naïve and TNFi-IR at Wk52. TRIAL REGISTRATION: NCT03895203, NCT03896581, NCT01009086, NCT01077362.

Comparative Effectiveness of Bimekizumab and Risankizumab in Patients with Psoriatic Arthritis at 52 Weeks Assessed Using a Matching-Adjusted Indirect Comparison.

INTRODUCTION: The relative efficacy of bimekizumab and risankizumab in patients with PsA who were biologic disease-modifying anti-rheumatic drug naïve (bDMARD naïve) or with previous inadequate response or intolerance to tumor necrosis factor inhibitors (TNFi-IR) was assessed at 52 weeks (Wk52) using matching-adjusted indirect comparisons (MAIC). METHODS: Relevant trials were systematically identified. For patients who were bDMARD naïve, individual patient data (IPD) from BE OPTIMAL (NCT03895203; N = 431) were matched with summary data from KEEPsAKE-1 (NCT03675308; N = 483). For patients who were TNFi-IR, IPD from BE COMPLETE (NCT03896581; N = 267) were matched with summary data from the TNFi-IR patient subgroup in KEEPsAKE-2 (NCT03671148; N = 106). To adjust for cross-trial differences, patients from the bimekizumab trials were re-weighted to match the baseline characteristics of patients in the risankizumab trials. Adjustment variables were selected based on expert consensus (n = 5) and adherence to established MAIC guidelines. Recalculated bimekizumab Wk52 outcomes for American College of Rheumatology (ACR) 20/50/70 response criteria and minimal disease activity (MDA) index (non-responder imputation) were compared with risankizumab outcomes via non-placebo-adjusted comparisons. RESULTS: In patients who were bDMARD naïve, bimekizumab had a significantly greater likelihood of response than risankizumab at Wk52 for ACR50 (odds ratio [95% confidence interval]: 1.52 [1.11, 2.09]) and ACR70 (1.80 [1.29, 2.51]). In patients who were TNFi-IR, bimekizumab had a significantly greater likelihood of response than risankizumab at Wk52 for ACR20 (1.78 [1.08, 2.96]), ACR50 (3.05 [1.74, 5.32]), ACR70 (3.69 [1.82, 7.46]), and MDA (2.43 [1.37, 4.32]). CONCLUSIONS: Using MAIC, bimekizumab demonstrated a greater likelihood of efficacy in most ACR and MDA outcomes than risankizumab in patients with PsA who were bDMARD naïve and TNFi-IR at Wk52. TRIAL REGISTRATION: NCT03895203, NCT03896581, NCT03675308, NCT03671148.

Safety and Efficacy of Bimekizumab in Patients with Psoriatic Arthritis: 2-Year Results from Two Phase 3 Studies.

INTRODUCTION: Psoriatic arthritis (PsA) is a chronic inflammatory disease requiring long-term treatment. Bimekizumab, a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A, has demonstrated tolerability and sustained clinical efficacy for up to 1 year for patients with PsA. Here, we report the longer-|term safety and efficacy of bimekizumab up to 2 years. METHODS: BE OPTIMAL (biologic disease-modifying antirheumatic drug [bDMARD]-naïve) and BE COMPLETE (prior inadequate response/intolerance to tumor necrosis factor inhibitors [TNFi-IR]) assessed subcutaneous bimekizumab 160 mg every 4 weeks in patients with PsA. BE OPTIMAL included a reference arm (adalimumab 40 mg every 2 weeks); patients switched to bimekizumab at week 52 with no washout between treatments. BE OPTIMAL week 52 and BE COMPLETE week 16 completers were eligible for the BE VITAL open-label extension. Efficacy outcomes are reported to week 104/100 (BE OPTIMAL/BE COMPLETE). RESULTS: A total of 710/852 (83.3%) bDMARD-naïve and 322/400 (80.5%) TNFi-IR patients completed week 104/100. Up to 104 weeks, patients treated with bimekizumab in BE OPTIMAL and BE COMPLETE had treatment-emergent adverse event incidence rates (exposure-adjusted incidence rate/100 patient-years) of 179.9 (95% CI 166.9, 193.7) and 100.3 (89.2, |112.4), respectively. The proportion of patients achieving efficacy outcomes (≥ 50% improvement from baseline in American College of Rheumatology [ACR] response criteria, 100% improvement from baseline in Psorisis Area and Severity Index [PASI], minimal disease activity [MDA]) was sustained in all patients from week 52 to week 104/100. CONCLUSIONS: Bimekizumab was well tolerated for up to 2 years of treatment and no new safety signals were observed. Sustained clinical efficacy was observed up to 2 years in bDMARD-naïve and TNFi-IR patients with active PsA. Patients switching from adalimumab to bimekizumab demonstrated further improvement in skin and nail symptoms, and sustained efficacy in joint symptoms. TRIAL REGISTRATION: BE OPTIMAL (NCT03895203), BE COMPLETE (NCT03896581), BE VITAL (NCT04009499).

Adherence, Persistence, Healthcare Resource Use, and Costs in Tofacitinib-Treated Patients with Psoriatic Arthritis: Data from Two United States Claims Databases.

INTRODUCTION: Associations between increased functional disability and higher healthcare resource utilization (HCRU) and costs were reported in patients with psoriatic arthritis (PsA). We assessed characteristics/outcomes of patients with PsA receiving tofacitinib monotherapy vs combination therapy with conventional synthetic disease-modifying antirheumatic drugs. METHODS: Claims data from Optum® Clinformatics® Data Mart (OC) and Merative™ MarketScan® (MS) databases between December 2017 and February 2020 were analyzed. Outcomes assessed were adherence/persistence by therapy type (monotherapy/combination therapy); HCRU/costs (per patient per month) by periods on-treatment (sum time on tofacitinib) and off-treatment (sum time off tofacitinib [gap of > 60 days]) plus therapy type. RESULTS: This analysis included 274 and 395 tofacitinib-treated patients in OC (70.4% female, mean age 54.4 years) and MS (68.9% female, mean age 51.4 years), respectively. Percentages of patients with a proportion of days covered ≥ 0.8 at 12 months for monotherapy vs combination therapy were OC, 44.5% vs 53.8%; MS, 36.4% vs 45.7%. Generally similar trends were seen over 24 months and for medication possession ratio ≥ 0.8. Median (95% confidence interval) times to treatment discontinuation for monotherapy vs combination therapy were OC, 10.1 (7.4-11.8) vs 16.7 (8.3-26.6) months; MS, 6.9 (5.6-9.4) vs 11.0 (6.1-13.9) months. During off-treatment vs on-treatment periods, numerical decreases were observed for all-cause (OC, $5383 vs $6149; MS, $4145 vs $5180) and PsA-related costs (OC, $3237 vs $4515; MS, $2703 vs $3907) regardless of therapy type. During off-treatment vs on-treatment periods, numerical increases in outpatient visits for all-cause (OC, 2.37 vs 2.05; MS, 2.15 vs 1.99) and PsA-related visits (OC, 0.60 vs 0.46; MS, 0.47 vs 0.44) were observed, and PsA-related medications numerically decreased (OC, 1.21 vs 1.53; MS, 1.05 vs 1.48). CONCLUSION: In this USA-based claims analysis, tofacitinib adherence was numerically lower for patients with PsA receiving monotherapy vs combination therapy. Costs numerically decreased off-treatment vs on-treatment, irrespective of therapy type, driven by lower medication costs.

Treatment of early oligoarticular psoriatic arthritis with apremilast: primary outcomes at week 16 from the FOREMOST randomised controlled trial.

OBJECTIVES: Oligoarticular psoriatic arthritis (PsA) is frequent but rarely studied. The objective was to assess the efficacy of apremilast in early oligoarticular PsA. METHODS: FOREMOST (NCT03747939) was a phase 4 multicentre, randomised, double-blind, placebo-controlled trial. Patients had early (symptom duration ≤5 years) oligoarticular PsA (>1 but ≤4 swollen and >1 but ≤4 tender joints; 2-8 total active joints). Patients were randomised 2:1 to apremilast 30 mg two times per day or placebo for 24 weeks, with an early escape at week 16. The primary endpoint was the proportion of patients at week 16 who achieved minimal disease activity (MDA)-Joints (modification of MDA mandating ≤1 swollen joint and ≤1 tender joint) based on sentinel joints (those affected at baseline) with a combination of non-responder imputation and multiple imputations. Exploratory analysis assessed all joints. RESULTS: Of 308 patients randomised (apremilast: n=203; placebo: n=105), mean (SD) PsA duration was 9.9 (10.2) months, mean (SD) age was 50.9 (12.5) years and 39.9% of patients were using a conventional synthetic disease-modifying antirheumatic drug. MDA-Joints (sentinel joints (primary endpoint) and all joints) were achieved by significantly more patients with apremilast (33.9% and 21.3%) vs placebo (16.0% and 7.9%) at week 16 (p=0.0008 and nominal p=0.0028, respectively). Greater improvements in patient-reported outcomes, clinical disease activity and skin involvement were also seen with apremilast versus placebo. CONCLUSIONS: FOREMOST is the first randomised controlled trial designed for early oligoarticular PsA and showed apremilast improves clinical and patient-reported outcomes. This trial may inform the optimal management of PsA in these patients. TRIAL REGISTRATION NUMBER: NCT03747939.

A secukinumab dose-escalation study in patients with ankylosing spondylitis not achieving inactive disease after 16 weeks of treatment.

OBJECTIVE: To investigate the clinical response at week 52 in patients with ankylosing spondylitis (AS) who received secukinumab 300 vs 150 mg after inadequate response to 150 mg at week 16. METHODS: ASLeap (NCT03350815) was a randomized, double-blind, parallel-group, multicentre, phase 4 trial. After 16 weeks of open-label secukinumab 150 mg (Treatment Period 1), patients who did not achieve inactive disease (Ankylosing Spondylitis Disease Activity Score [ASDAS] <1.3) at both Weeks 12 and 16 were considered to have an inadequate response and were randomized 1:1 to receive secukinumab 300 or 150 mg every 4 weeks until week 52 (Treatment Period 2). The primary efficacy variable was achievement of ASDAS <1.3 at week 52 using week 16 as baseline. Safety was evaluated by the incidence of treatment-emergent adverse events through week 52. RESULTS: Of 322 patients treated with secukinumab in Treatment Period 1, 207 (64.3%) had inadequate response. Similar proportions of patients with inadequate response randomized to secukinumab 300 mg (n = 101) and 150 mg (n = 105) in Treatment Period 2 completed the study (83.8% and 84.3%, respectively). At week 52, 8.8% and 6.7% of patients receiving secukinumab 300 and 150 mg, respectively, achieved ASDAS <1.3. The incidence of treatment-emergent adverse events was similar in both groups through week 52. No new safety signals were observed. CONCLUSION: Patients with AS who did not achieve ASDAS <1.3 after receiving secukinumab 150 mg for 16 weeks experienced similar clinical response and safety through week 52 regardless of dose escalation. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03350815.

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

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

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) Celebrates Its 20th Anniversary.

The Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) started in August 2003 with 40 initial participants and celebrated its 20th anniversary with 1036 members, many of whom attended the annual meeting in Dublin, Ireland, on July 15 to 17, 2023. GRAPPA arose from a need experienced by psoriatic arthritis (PsA) and psoriasis (PsO) investigators to meet to address questions related to psoriatic disease (PsD). Though other groups were meeting at the time to classify and discuss PsA, GRAPPA arose from a desire to include international clinical and investigational researchers of both dermatology and rheumatology. The organization has built awareness of PsO and PsA, developed and validated research assessment tools to measure clinical status and disease outcomes, published multiple treatment recommendations, supported basic and clinical research on PsD pathophysiology, fostered interactions across research fields, and educated the future generation of PsO and PsA researchers. The group continues to focus on major priorities affecting patients with PsD and will continue evolving in the next decades.

Updates were provided on GRAPPA research projects, including the Axial Involvement in Psoriatic Arthritis (AXIS), Axial Psoriatic Arthritis Molecular and Clinical Characterisation Study, Diagnostic Ultrasound Enthesitis Tool (DUET), and Sex- and Gender-Based Analysis of the Effectiveness of Advanced Therapies (SAGE) studies, as well as the Health Initiatives in Psoriasis and Psoriatic Arthritis Consortium European States (HIPPOCRATES) and Elucidating the Landscape of Immunoendotypes in Psoriatic Skin and Synovium (ELLIPSS) studies. The highlight of the meeting was a presentation and discussion on the use of digital tools to study psoriatic disease.

Efficacy and Safety of Bimekizumab in Patients With Psoriatic Arthritis With or Without Methotrexate: 52-Week Results From Two Phase 3 Studies.

OBJECTIVE: The objective of this study was to assess 52-week efficacy and safety of bimekizumab in patients with active psoriatic arthritis (PsA) with or without concomitant methotrexate (+/-MTX) treatment at baseline. METHODS: We conducted a post hoc analysis of patients in BE OPTIMAL (NCT03895203; biologic disease-modifying antirheumatic drug [bDMARD]-naïve), BE COMPLETE (NCT03896581; prior inadequate response or intolerance to tumor necrosis factor inhibitors [TNFi-IR]), and the BE VITAL open-label extension (NCT04009499) study. Patients were randomized to one of the following treatment groups: bimekizumab 160 mg every four weeks, placebo, or a reference drug (adalimumab 40 mg every two weeks; BE OPTIMAL only). From Week 16, placebo-randomized patients received bimekizumab. Missing data were imputed using non-responder imputation, multiple imputation, or worst-category imputation. RESULTS: Through Week 52, similar proportions of bimekizumab-treated patients achieved American College of Rheumatology 50% (ACR50) response criteria for both +MTX and -MTX (BE OPTIMAL: 54.4% +MTX, 54.7% -MTX; BE COMPLETE: 56.3% +MTX, 48.0% -MTX). Similar proportions of bimekizumab-treated patients achieved complete skin clearance (Psoriasis Area and Severity Index 100% [PASI100] response) and minimal disease activity in both +MTX and -MTX groups. Similar trends were seen in placebo/bimekizumab-treated patients. Through Week 52, the proportion of bimekizumab-treated patients with ≥1 treatment-emergent adverse event were similar between the +MTX and -MTX groups (BE OPTIMAL 325 of 410 [79.3%] vs 230 of 292 [78.8%], BE COMPLETE 105 of 168 [62.5%] vs 138 of 220 [62.7%]). The safety profile was comparable between subgroups and consistent with the prior safety profile of bimekizumab. CONCLUSION: Treatment with bimekizumab demonstrated consistent, sustained efficacy to 52 weeks in bDMARD-naïve and TNFi-IR patients with PsA and was well tolerated, irrespective of concomitant MTX.

Durable control of psoriatic arthritis with guselkumab across domains and patient characteristics: post hoc analysis of a phase 3 study.

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.

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

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

The Burden of Work Productivity and Activity Impairment in Patients with Psoriasis, Psoriatic Arthritis, Ulcerative Colitis, and Crohn's Disease.

BACKGROUND: Comparisons among autoimmune diseases enable understanding of the burden and factors associated with work productivity loss and impairment. AIMS: The objective was to compare work productivity and activity and associated factors among patients with inflammatory bowel diseases and other autoimmune conditions. METHODS: This cross-sectional study included employed, adult patients (age 20-64 years) in the CorEvitas Inflammatory Bowel Disease, Psoriasis, and Psoriatic Arthritis/Spondyloarthritis Registries between 5/2017 and 6/2020. Any patient-reported impairment on four domains of the Work Productivity and Activity Index (WPAI) was collected across registries. Prevalence for each autoimmune disease was reported and stratified by disease activity using direct age-sex-standardization. Factors associated with the presence of any WPAI were identified in logistic regression models. RESULTS: A total of 7,169 patients with psoriasis (n = 4,768, 67%), psoriatic arthritis (n = 1,208, 17%), Crohn's disease (CD, n = 621, 9%), and ulcerative colitis (UC, n = 572, 8%) met inclusion criteria. Among patients not in remission across all disease cohorts, the age-sex-standardized prevalence of any presenteeism, work productivity loss, and activity impairment ranged from 54 to 97%. Patients with CD in remission had higher standardized prevalence of presenteeism (53% [48-57%]) and work productivity loss (54% [49-59%]), compared to those from other cohorts (presenteeism [range: 33-39%] and work productivity loss [range: 37-41%]). For all WPAI domains, the strongest adjusted associations were for moderate to severe disease activity and psychosocial symptoms. CONCLUSIONS: Patients with moderate to severe disease activity reported the highest WPAI burden. However, patients in remission or mild disease activity also report some WPAI burden, emphasizing a multidisciplinary treatment approach to improve work productivity loss and impairment.

Phase 2 Trial of Deucravacitinib in Psoriatic Arthritis: Biomarkers Associated With Disease Activity, Pharmacodynamics, and Clinical Responses.

OBJECTIVE: Our objective was to evaluate the association of serum biomarkers with baseline psoriatic arthritis (PsA) disease activity, pharmacodynamic effects of deucravacitinib on biomarker levels, and the relationship between biomarkers and clinical responses to deucravacitinib. METHODS: The phase 2 trial (ClinicalTrials.gov identifier: NCT03881059) randomly assigned 203 patients with PsA 1:1:1 to placebo, deucravacitinib at 6 mg once daily (QD), or deucravacitinib at 12 mg QD. Serum biomarkers associated with the interleukin 23 (IL-23) pathway (IL-17A, ß-defensin [BD-2], and IL-19), type I interferon pathway, inflammation, and collagen matrix turnover were measured by immunoassay. Clinical responses (≥75% improvement from baseline in the Psoriasis Area and Severity Index [PASI75] and ≥20% improvement from baseline in American College of Rheumatology criteria [ACR20] responses) were measured at week 16. Hematologic variables were also assessed. RESULTS: IL-17A, BD-2, and IL-19 had a modest association with PASI scores (r = 0.4, r = 0.56, and r = 0.5, respectively) at baseline. In deucravacitinib groups, IL-17A, BD-2, IL-19, C-X-C motif ligand 9 (CXCL9), CXCL10, C-reactive protein, matrix metalloproteinase 3, and collagen type 4 degradation marker levels were significantly reduced at week 16 versus baseline (P < 0.01); higher levels of IL-23 pathway-associated biomarkers predicted higher PASI75 and ACR20 response rates in deucravacitinib-treated patients. Significantly higher PASI75 response rates were seen in patients with high baseline IL-17A (odds ratio 15.76) and BD-2 levels (odds ratio 15.41) versus low baseline IL-17A and BD-2 levels. Changes in hematologic variables that are characteristic of JAK inhibition were not observed with deucravacitinib. CONCLUSION: Deucravacitinib significantly impacted biomarkers associated with Tyk2 signaling pathways of key inflammatory cytokines, including IL-23 and type I interferon, and those related to collagen matrix turnover. These biomarkers may predict treatment responses to deucravacitinib.

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

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

Efficacy and safety of guselkumab in patients with active psoriatic arthritis who had inadequate efficacy and/or intolerance to one prior tumor necrosis factor inhibitor: study protocol for SOLSTICE, a phase 3B, multicenter, randomized, double-blind, placebo-controlled study.

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.

Navigating the complexity of pain in psoriatic arthritis and axial spondyloarthritis.

PURPOSE OF REVIEW: Pain is the most common and often most troublesome feature of chronic autoimmune diseases such as psoriatic arthritis (PsA) and axial spondyloarthritis (AxSpA). A predominant concept is that the main source of pain is from disease-induced tissue inflammation and structural damage, activating peripheral nerve fibers which relay to the central nervous system. This mechanism is nociceptive pain and the presumption has been that controlling inflammation will be sufficient to reduce this form of pain. However, despite control of inflammation, patients may still have significant residual pain. RECENT FINDINGS: We are learning that there are additional pain mechanisms, neuropathic and nociplastic, that are often operative in patients with rheumatologic conditions, that can significantly influence pain experience, quantitation of disease activity, and may benefit from therapeutic approaches distinct from immunotherapy. Neuropathic pain arises from diseased or damaged nerve tissue and nociplastic pain reflects sensitization of the central nervous system due to multiple genetic, neurobiologic, neural network dysregulation, and psychosocial factors. Pain arising from these mechanisms influence assessment of disease activity and thus needs to be factored into decision-making about immunotherapy efficacy. SUMMARY: This review addresses the importance of accurately assessing the complex mechanisms of pain experience in patients with PsA and AxSpA to more appropriately manage immunomodulatory, neuromodulatory, and nonpharmacologic therapies.

Machine learning to understand risks for severe COVID-19 outcomes: a retrospective cohort study of immune-mediated inflammatory diseases, immunomodulatory medications, and comorbidities in a large US health-care system.

BACKGROUND: In the context of immune-mediated inflammatory diseases (IMIDs), COVID-19 outcomes are incompletely understood and vary considerably depending on the patient population studied. We aimed to analyse severe COVID-19 outcomes and to investigate the effects of the pandemic time period and the risks associated with individual IMIDs, classes of immunomodulatory medications (IMMs), chronic comorbidities, and COVID-19 vaccination status. METHODS: In this retrospective cohort study, clinical data were derived from the electronic health records of an integrated health-care system serving patients in 51 hospitals and 1085 clinics across seven US states (Providence St Joseph Health). Data were observed for patients (no age restriction) with one or more IMID and for unmatched controls without IMIDs. COVID-19 was identified with a positive nucleic acid amplification test result for SARS-CoV-2. Two timeframes were analysed: March 1, 2020-Dec 25, 2021 (pre-omicron period), and Dec 26, 2021-Aug 30, 2022 (omicron-predominant period). Primary outcomes were hospitalisation, mechanical ventilation, and mortality in patients with COVID-19. Factors, including IMID diagnoses, comorbidities, long-term use of IMMs, and COVID-19 vaccination status, were analysed with multivariable logistic regression (LR) and extreme gradient boosting (XGB). FINDINGS: Of 2 167 656 patients tested for SARS-CoV-2, 290 855 (13·4%) had confirmed COVID-19: 15 397 (5·3%) patients with IMIDs and 275 458 (94·7%) without IMIDs. In the pre-omicron period, 169 993 (11·2%) of 1 517 295 people who were tested for COVID-19 tested positive, of whom 23 330 (13·7%) were hospitalised, 1072 (0·6%) received mechanical ventilation, and 5294 (3·1%) died. Compared with controls, patients with IMIDs and COVID-19 had higher rates of hospitalisation (1176 [14·6%] vs 22 154 [13·7%]; p=0·024) and mortality (314 [3·9%] vs 4980 [3·1%]; p<0·0001). In the omicron-predominant period, 120 862 (18·6%) of 650 361 patients tested positive for COVID-19, of whom 14 504 (12·0%) were hospitalised, 567 (0·5%) received mechanical ventilation, and 2001 (1·7%) died. Compared with controls, patients with IMIDs and COVID-19 (7327 [17·3%] of 42 249) had higher rates of hospitalisation (13 422 [11·8%] vs 1082 [14·8%]; p<0·0001) and mortality (1814 [1·6%] vs 187 [2·6%]; p<0·0001). Age was a risk factor for worse outcomes (adjusted odds ratio [OR] from 2·1 [95% CI 2·0-2·1]; p<0·0001 to 3·0 [2·9-3·0]; p<0·0001), whereas COVID-19 vaccination (from 0·082 [0·080-0·085]; p<0·0001 to 0·52 [0·50-0·53]; p<0·0001) and booster vaccination (from 2·1 [2·0-2·2]; p<0·0001 to 3·0 [2·9-3·0]; p<0·0001) status were associated with better outcomes. Seven chronic comorbidities were significant risk factors during both time periods for all three outcomes: atrial fibrillation, coronary artery disease, heart failure, chronic kidney disease, chronic obstructive pulmonary disease, chronic liver disease, and cancer. Two IMIDs, asthma (adjusted OR from 0·33 [0·32-0·34]; p<0·0001 to 0·49 [0·48-0·51]; p<0·0001) and psoriasis (from 0·52 [0·48-0·56] to 0·80 [0·74-0·87]; p<0·0001), were associated with a reduced risk of severe outcomes. IMID diagnoses did not appear to be significant risk factors themselves, but results were limited by small sample size, and vasculitis had high feature importance in LR. IMMs did not appear to be significant, but less frequently used IMMs were limited by sample size. XGB outperformed LR, with the area under the receiver operating characteristic curve for models across different time periods and outcomes ranging from 0·77 to 0·92. INTERPRETATION: Our results suggest that age, chronic comorbidities, and not being fully vaccinated might be greater risk factors for severe COVID-19 outcomes in patients with IMIDs than the use of IMMs or the IMIDs themselves. Overall, there is a need to take age and comorbidities into consideration when developing COVID-19 guidelines for patients with IMIDs. Further research is needed for specific IMIDs (including IMID severity at the time of SARS-CoV-2 infection) and IMMs (considering dosage and timing before a patient's first COVID-19 infection).

Association of clinical response criteria and disease activity levels with axial spondyloarthritis core domains: results from two phase 3 randomised studies, BE MOBILE 1 and 2.

OBJECTIVE: To assess how achievement of increasingly stringent clinical response criteria and disease activity states at week 52 translate into changes in core domains in patients with non-radiographic (nr-) and radiographic (r-) axial spondyloarthritis (axSpA). METHODS: Patients in BE MOBILE 1 and 2 achieving different levels of response or disease activity (Assessment of SpondyloArthritis International Society (ASAS) and Ankylosing Spondylitis Disease Activity Score (ASDAS) response criteria, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI50)) at week 52 were pooled, regardless of treatment arm. Associations between achievement of these endpoints and change from baseline (CfB) in patient-reported outcomes (PROs) measuring core axSpA domains, including pain, fatigue, physical function, overall functioning and health, and work and employment, were assessed. RESULTS: Achievement of increasingly stringent clinical efficacy endpoints at week 52 was generally associated with sequentially greater improvements from baseline in all PROs. Patients with nr-axSpA achieving ASAS40 demonstrated greater improvements (CfB) than patients who did not achieve ASAS40 but did achieve ASAS20, in total spinal pain (-5.3 vs -2.8, respectively), Functional Assessment of Chronic Illness-Fatigue subscale (12.7 vs 6.7), Bath Ankylosing Spondylitis Function Index (-3.9 vs -1.8), European Quality of Life 5-Dimension 3-Level Version (0.30 vs 0.16), Work Productivity and Activity Impairment-axSpA presenteeism (-35.4 vs -15.9), overall work impairment (-36.5 vs -12.9), activity impairment (-39.0 vs -21.0) and sleep (9.0 vs 3.9). Results were similar for ASDAS and BASDAI50. Similar amplitudes of improvement were observed between patients with nr-axSpA and r-axSpA. CONCLUSIONS: Patients treated with bimekizumab across the full axSpA disease spectrum, who achieved increasingly stringent clinical response criteria and lower disease activity at week 52, reported larger improvements in core axSpA domains.
