Lavie F, Rooney T. Hurdles in new drug development in rheumatic diseases. Joint Bone Spine 2024; 91:105672. [PMID: 38042361 DOI: 10.1016/j.jbspin.2023.105672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 11/05/2023] [Accepted: 11/14/2023] [Indexed: 12/04/2023]
Abstract
INTRODUCTION Rheumatic diseases are heterogenous conditions with multifactorial underlying physiologic pathogeneses. Despite recent progress in the identification and development of advanced therapies primarily focusing on disrupting the immunological abnormalities that cause these conditions, rheumatic disease management remains challenging in a notable proportion of patients, with many exhibiting uncontrolled or refractory disease activity. New and improved therapies are needed to respond to this treatment gap. However, there are important hurdles that can affect the expedited identification and assessment of new treatments. METHODS We present a review of key hurdles in the development of antirheumatic agents, as well as possible solutions to these obstacles. RESULTS We highlight the challenges presented by incomplete understanding of the complexity of rheumatic disease pathophysiology and the resultant difficulties in the identification, development, and evaluation of new therapies. We further explore the diversity of the underlying disease processes leading to heterogeneity in patient response to treatment, necessitating the re-design of clinical trials of antirheumatic agents to detect efficacy signals and better inform clinical disease management. Finally, emergent strategies and methodologies with potential to improve upon these hurdles are presented. CONCLUSION New and modified study designs and research tools that leverage ongoing advancements in the elucidation of rheumatic disease pathogenesis coupled with progress in methods to mine available data will be instrumental in overcoming current hurdles in antirheumatic drug development.

Abstract
We present the motivation, experience, and learnings from a data challenge conducted at a large pharmaceutical corporation on the topic of subgroup identification. The data challenge aimed at exploring approaches to subgroup identification for future clinical trials. To mimic a realistic setting, participants had access to 4 Phase III clinical trials to derive a subgroup and predict its treatment effect on a future study not accessible to challenge participants. A total of 30 teams registered for the challenge with around 100 participants, primarily from Biostatistics organization. We outline the motivation for running the challenge, the challenge rules, and logistics. Finally, we present the results of the challenge, the participant feedback as well as the learnings. We also present our view on the implications of the results on exploratory analyses related to treatment effect heterogeneity.

Abstract
The American College of Rheumatology and the US Food and Drug Administration co-sponsored a public meeting in May 2022 about challenges in the clinical development of drugs for rheumatoid arthritis (RA) and psoriatic arthritis (PsA), focusing on innovative clinical trial designs, outcome measures, and data collection methods. Recommendations include early dose-ranging studies and use of active comparators. Challenges and opportunities in assessing long-term safety by leveraging real-world data from electronic health records (EHRs) and claims data are discussed, along with insights from European registries and the evolving role of real-world evidence and artificial intelligence in regulatory evaluations. Endpoints for assessing disease activity and outcome measures used in RA and PsA trials are explored, emphasizing challenges in defining remission, assessing clinical response, and evaluating structural progression. The need for outcome measures that better reflect treatment targets and the potential of advanced imaging in future trials are highlighted. Challenges with placebo-controlled trials in RA are discussed and use of non-inferiority clinical trial design, in which new drugs are evaluated with active comparators, is proposed. Pragmatic trials in RA and PsA, employing decentralized approaches, are highlighted for their real-world relevance and administrative efficiencies. Strategies for identifying at-risk populations for RA and the challenges of using EHRs and insurance claims data in drug development are discussed. Registry data and digital health technologies show promise in bridging the gap between clinical trials and real-world effectiveness.

Abstract
OBJECTIVE To determine the responsiveness to therapy and minimum clinically important improvement (MCII) for patient-reported outcome measures in psoriatic arthritis (PsA) and to examine the impact of baseline disease activity on the ability to demonstrate change. METHODS A longitudinal cohort study was performed within the PsA Research Consortium. Patients completed several patient-reported outcomes, including the Routine Assessment of Patient Index Data, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Psoriatic Arthritis Impact of Disease 12-item (PsAID12) questionnaire, and others. The mean change in the scores between visits and standardized response means (SRMs) were calculated. The MCII was calculated as the mean change in score among patients who reported minimal improvement. SRMs and MCIIs were compared among subgroups with moderate to highly active PsA and those with lower disease activity. RESULTS Among 171 patients, 266 therapy courses were included. The mean ± SD age was 51 ± 13.8 years, 53% were female, and the mean swollen and tender joint counts were 3 and 6, respectively, at baseline. SRMs and MCII for all measures were small to moderate, although greater among those with higher baseline disease activity. BASDAI had the best SRM overall and for less active PsA, and the clinical Disease Activity of PsA (cDAPSA) and PsAID12 were best for those with higher disease activity. CONCLUSION SRMs and MCII were relatively small in this real-world population, particularly among those with lower disease activity at baseline. BASDAI, cDAPSA, and PsAID12 had good sensitivity to change, but selection for use in trials should consider the baseline disease activity of patients to be enrolled.

Abstract
BACKGROUND To evaluate the real-world effect of the IL-12/23 inhibitor ustekinumab or of a tumour necrosis factor inhibitor (TNFi) on patient-reported outcomes (PRO) and their association with effectiveness endpoints in psoriatic arthritis (PsA) patients over 3 years. METHODS In PsABio (NCT02627768), a prospective, observational study, patients with PsA that were prescribed first- to third-line ustekinumab or a TNFi, and remained on that drug for 3 years, were analysed for change in baseline in PROs (EuroQol-5 dimensions health state VAS [EQ-5D VAS], 12-item Psoriatic Arthritis Impact of Disease questionnaire [PsAID-12; range 0-10], Work Productivity and Activity Impairment for Psoriatic Arthritis questionnaire [WPAI; results expressed as a percentage for each domain]), and the association between PROs and WPAI with effectiveness endpoints, clinical disease activity index for psoriatic arthritis (cDAPSA), low disease activity (LDA)/remission, minimal disease activity (MDA) and very low disease activity (VLDA). RESULTS In 437 patients (mean age 49.1 years, 47.8% female), at 3 years, ustekinumab and TNFi treatment led to comparable improvements in EQ-5D VAS; mean change from baseline (95% confidence intervals [CI]) was 11.0 (6.5; 15.4) and 18.9 (14.0; 23.9), respectively. Both groups improved PsAID-12 after 3 years; mean change from baseline (95% CI) was -2.9 (-3.2; -2.5) and -3.5 (-3.9; -3.2), respectively. At baseline, due to their PsA, TNFi-treated patients had lower work productivity compared to ustekinumab-treated patients; mean productivity reduction (95% CI) was 58.8 [52.4; 65.2] and 43.3 [35.6; 51.1]. Over 3 years, TNFi-treated patients had a greater improvement in work productivity compared to ustekinumab-treated patients, ultimately leaving work productivity to be comparable between groups; mean improvement (95% CI) was 44.5% (38.4; 50.6) and 24.9% (15.8; 34.0), respectively. A similar trend was observed in activity impairment. Patients in both treatment groups who achieved effectiveness endpoints, cDAPSA LDA/remission, MDA, and VLDA had greater improvement in PROs and WPAI than patients who did not achieve these endpoints. CONCLUSIONS At 3 years, improvements in PROs following ustekinumab or TNFi treatment were generally comparable; however, TNFi-treated patients achieved a greater improvement in work productivity, although this group started from a lower baseline. Achievement of effectiveness endpoints, independent of treatment group, also improved PROs. TRIAL REGISTRATION ClinicalTrials.gov, NCT02627768. Registered on 11 December 2015.

Semin Arthritis Rheum 2023; 58:152134.

Abstract
OBJECTIVE To compare achievement of Disease Activity Index in Psoriatic Arthritis (DAPSA) remission (REM)/low disease activity (LDA) with very low disease activity (VLDA)/minimal disease activity (MDA) targets in tofacitinib-treated patients with psoriatic arthritis (PsA). METHODS In this post hoc analysis, data were pooled from two phase 3 studies (6 months' [NCT01882439] and 12 months' [NCT01877668] duration) of patients with PsA receiving tofacitinib 5 or 10 mg twice daily. Cut-offs for DAPSA targets: ≤4 for clinical REM and >4-≤14 for LDA. VLDA and MDA were defined as meeting 7 or ≥5, respectively, of 7 criteria. An ordered logistic regression model was performed to evaluate associations between baseline characteristics and achievement of DAPSA targets as well as VLDA/MDA at month 3. Agreement between achieving DAPSA and VLDA/MDA targets at months 1-6 was assessed via kappa tests. Change from baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) and Short Form-36 Health Survey (SF-36) Physical Component Summary (PCS) scores (month 6), modified Total Sharp Score (mTSS) and proportion of radiographic non-progressors (mTSS ≤0.5) at month 12 (NCT01877668 only) were compared across DAPSA and VLDA/MDA targets. RESULTS Increased disease activity at baseline was associated with reduced likelihood of achieving DAPSA-REM/DAPSA-LDA or VLDA/MDA at month 3. There was moderate agreement (kappa values 0.41-0.60) between DAPSA-REM and VLDA, and DAPSA-LDA and MDA, from months 1 to 6, although over half of patients achieving DAPSA-REM and over two thirds of patients achieving DAPSA-LDA, respectively, were not captured by VLDA and MDA. Achieving DAPSA-REM/DAPSA-LDA or VLDA/MDA was associated with improved HAQ-DI and SF-36 PCS scores at month 6, and slightly reduced radiographic progression at month 12. CONCLUSION This analysis of data from tofacitinib-treated patients with PsA demonstrated moderate agreement between the DAPSA and VLDA/MDA composite instruments. In agreement with previous studies, VLDA and MDA may be more difficult to achieve than DAPSA-REM and DAPSA-LDA, respectively. However, the clinical and prognostic relevance of this finding should be determined. These data support DAPSA and VLDA/MDA as useful tools for evaluating disease activity and treatment response in PsA. CLINICALTRIALS GOV: NCT01882439; NCT01877668.

The incidence of opportunistic infections in patients with psoriatic arthritis treated with biologic and targeted synthetic agents: A systematic review and meta-analysis. Front Pharmacol 2022; 13:992713. [PMID: 36278224 PMCID: PMC9579334 DOI: 10.3389/fphar.2022.992713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Accepted: 09/20/2022] [Indexed: 11/13/2022] Open
Abstract
Background: Biologic (bDMARD) and targeted synthetic (tsDMARD) disease-modifying anti-rheumatic drugs have broadened the treatment options and are increasingly used for patients with psoriatic arthritis (PsA). These agents block different pro-inflammatory cytokines or specific intracellular signaling pathways that promote inflammation and can place patients at risk of serious infections. We aimed to review the incidence of opportunistic infections (OIs) in patients with PsA who were treated with these agents.Methods: We searched PubMed and EMBASE through 14 April 2022 for randomized clinical trials evaluating bDMARD or tsDMARD in the treatment of PsA. Trials were eligible if they compared the effect of a bDMARD or tsDMARD with placebo and provided safety data. We used the Revised Cochrane risk-of-bias tool to assess the risk of bias among trials, and stratified the studies by mechanism of action (MOA) of the agents studied.Results: We included 47 studies in this analysis. A total of 17,197 patients received at least one dose of an agent of interest. The cumulative incidence of OIs by MOA was as follows: 1) JAK inhibitors: 2.72% (95% CI: 1.05%–5.04%), 2) anti-IL-17: 1.18% (95% CI: 0.60%–1.9%), 3) anti-IL-23: 0.24% (95% CI: 0.04%–0.54%), and 4) anti-TNFs: 0.01% (95% CI: 0.00%–0.21%). Based on their MOA, these agents are known to increase the risk of certain serious infections. The cumulative incidence of herpes zoster infection following treatment with JAK inhibitors (JAKi) was 2.53% (95% CI: 1.03%–4.57%) and the cumulative incidence of opportunistic Candida spp. infections following treatment with anti-IL-17, was 0.97% (95% CI: 0.51%–1.56%).Conclusion: The overall incidence of OIs among patients with PsA who were treated with biologic and targeted synthetic agents is low. However, careful monitoring is warranted for specific OIs such as herpes zoster infection following JAKi treatment, mucocutaneous candidiasis following anti-IL-17 treatment, and Mycobacterium tuberculosis infection following anti-TNF treatment.

Abstract
Background Rheumatological and dermatological disorders contribute to a significant portion of the global burden of disease. Big Data are increasingly having a more and more relevant role, being highly ubiquitous and pervasive in contemporary society and paving the way for new, unprecedented perspectives in biomedicine, including dermatology and rheumatology. Rheumatology and dermatology can potentially benefit from Big Data. Methods A systematic review of the literature was conducted according to the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses” (PRISMA) guidelines, mining “Uno per tutti”, a highly integrated and automated tool/meta-database developed at the University of Genoa, Genoa, Italy, and consisting of 20 major scholarly electronic databases, including PubMed/MEDLINE. Big Data- or artificial intelligence-based studies were judged based on the modified Qiao’s critical appraisal tool for critical methodological quality assessment of Big Data/machine learning-based studies. Other studies designed as cross-sectional, longitudinal, or randomized investigations, reviews/overviews or expert opinions/commentaries were evaluated by means of the relevant “Joanna Briggs Institute” (JBI)’s critical appraisal tool for the critical methodological quality assessment. Results Fourteen papers were included in the present systematic review of the literature. Most of the studies included concerned molecular applications of Big Data, especially in the fields of genomics and post-genomics. Other studies concerned epidemiological applications, with a practical dearth of studies assessing smart and digital applications for psoriatic arthritis patients. Conclusions Big Data can be a real paradigm shift that revolutionizes rheumatological and dermatological practice and clinical research, helping to early intercept psoriatic arthritis patients. However, there are some methodological issues that should be properly addressed (like recording and association biases) and some ethical issues that should be considered (such as privacy). Therefore, further research in the field is warranted. Systematic Review Registration Registration code 10.17605/OSF.IO/4KCU2.

Abstract
Introduction Despite recent advances in treatment for psoriatic arthritis (PsA), many patients experience inadequate response or intolerance to therapy, indicating that unmet treatment-related needs remain. To further characterize these unmet needs, we evaluated patients’ experiences regarding the burden of PsA symptoms and disease impacts, and patients’ preferences for treatment. Methods Patients from ArthritisPower, a rheumatology research registry, completed a web-based survey. Object case best–worst scaling (BWS) was used to evaluate the relative burden of 11 PsA-related symptoms and the relative importance of improvement in nine PsA-related disease impacts. BWS data were analyzed using a random-parameters logit model. Patient demographics, preferences for mode and frequency of therapy, and preferences for methotrexate were analyzed descriptively. Results Among the 332 participants, most were White (94%), female (80%), with mean age of 54 years (SD 11.4). In the BWS, joint pain was the most bothersome symptom, followed by other musculoskeletal pain and fatigue. The BWS for disease impacts found that improvements in the ability to perform physical activities were most important, followed by improvements in the ability to function independently, sleep quality, and the ability to perform daily activities. The most burdensome symptoms and desired disease impact improvements were similar in patients regardless of their experience with biologic disease-modifying antirheumatic drugs. The most preferred mode and frequency of treatment administration was oral, once-daily medication (preferred by 38% of respondents), and 74% prioritized therapies that significantly improved joint-related symptoms versus psoriasis-related symptoms. The majority of respondents (65%) preferred PsA treatment regimens that did not include methotrexate. Conclusions Patients with PsA from a rheumatology registry found musculoskeletal pain symptoms to be the most bothersome and prioritized improvements to functional impacts of their disease. These findings can better inform development of new therapies and guide shared patient-provider treatment decision-making.

Abstract
BACKGROUND Using a machine learning approach, the study investigated if specific baseline characteristics could predict which psoriatic arthritis (PsA) patients may gain additional benefit from a starting dose of secukinumab 300 mg over 150 mg. We also report results from individual patient efficacy meta-analysis (IPEM) in 2049 PsA patients from the FUTURE 2 to 5 studies to evaluate the efficacy of secukinumab 300 mg, 150 mg with and without loading regimen versus placebo at week 16 on achievement of several clinically relevant difficult-to-achieve (higher hurdle) endpoints. METHODS Machine learning employed Bayesian elastic net to analyze baseline data of 2148 PsA patients investigating 275 predictors. For IPEM, results were presented as difference in response rates versus placebo at week 16. RESULTS Machine learning showed secukinumab 300 mg has additional benefits in patients who are anti-tumor necrosis factor-naive, treated with 1 prior anti-tumor necrosis factor agent, not receiving methotrexate, with enthesitis at baseline, and with shorter PsA disease duration. For IPEM, at week 16, all secukinumab doses had greater treatment effect (%) versus placebo for higher hurdle endpoints in the overall population and in all subgroups; 300-mg dose had greater treatment effect than 150 mg for all endpoints in overall population and most subgroups. CONCLUSIONS Machine learning identified predictors for additional benefit of secukinumab 300 mg compared with 150 mg dose. Individual patient efficacy meta-analysis showed that secukinumab 300 mg provided greater improvements compared with 150 mg in higher hurdle efficacy endpoints in patients with active PsA in the overall population and most subgroups with various levels of baseline disease activity and psoriasis.

Abstract
BACKGROUND/AIMS Design of clinical trials requires careful decision-making across several dimensions, including endpoints, eligibility criteria, and subgroup enrichment. Clinical trial simulation can be an informative tool in trial design, providing empirical evidence by which to evaluate and compare the results of hypothetical trials with varying designs. We introduce a novel simulation-based approach using observational data to inform the design of a future pragmatic trial. METHODS We utilize propensity score-adjusted models to simulate hypothetical trials under alternative endpoints and enrollment criteria. We apply our approach to the design of pragmatic trials in psoriatic arthritis, using observational data embedded within the Tight Control of Inflammation in Early Psoriatic Arthritis study to simulate hypothetical open-label trials comparing treatment with tumor necrosis factor-α inhibitors to methotrexate. We first validate our simulations of a trial with traditional enrollment criteria and endpoints against a recently published trial. Next, we compare simulated treatment effects in patient populations defined by traditional and broadened enrollment criteria, where the latter is consistent with a future pragmatic trial. In each trial, we also consider five candidate primary endpoints. RESULTS Our results highlight how changes in the enrolled population and primary endpoints may qualitatively alter study findings and the ability to detect heterogeneous treatment effects between clinical subgroups. For treatments of interest in the study of psoriatic arthritis, broadened enrollment criteria led to diluted estimated treatment effects. Endpoints with greater responsiveness to treatment compared with a traditionally used endpoint were identified. These considerations, among others, are important for designing a future pragmatic trial aimed at having high external validity with relevance for real-world clinical practice. CONCLUSION Observational data may be leveraged to inform design decisions in pragmatic trials. Our approach may be generalized to the study of other conditions where existing trial data are limited or do not generalize well to real-world clinical practice, but where observational data are available.

Rheumatol Ther 2021; 8:1223-1240. [PMID: 34218429 PMCID: PMC8380608 DOI: 10.1007/s40744-021-00337-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Accepted: 06/14/2021] [Indexed: 11/28/2022] Open
Abstract
Background Psoriatic arthritis (PsA) is a chronic, heterogeneous, immune-mediated disease manifesting as a spectrum of possible inflammatory signs and symptoms. Clinicians need therapeutic choices that work across all active PsA disease domains, as well as practical information about efficacy of available treatments for individual domains in specific groups of patients. The objective of this study was to evaluate the effect of prior tumor necrosis factor inhibitor (TNFi) exposure on the efficacy of secukinumab across PsA core domains. Methods Data were pooled from 2049 participants with PsA in four phase 3 studies (FUTURE 2–5). Efficacy at week 16 was evaluated for each GRAPPA-OMERACT PsA core domain using nonresponder imputation for musculoskeletal disease activity and Psoriasis Area and Severity Index scores or as-observed data for other outcomes. For each measure, comparisons with placebo were made separately in the TNFi-naive and TNFi-inadequate responder/intolerant (TNF-IR) cohorts. Results Treatment with secukinumab improved PsA disease activity across all disease domains regardless of previous TNFi use, although TNFi-naive patients experienced numerically greater benefits in most outcomes. Among patients treated with secukinumab 300 mg, 41.5% and 24.4% of TNFi-naive patients (P < 0.05 vs placebo) and 18.6% and 9.0% of TNF-IR patients (nonsignificant vs placebo) experienced resolution in 66 swollen and 68 tender joint counts, respectively; additionally, 37.2% of TNFi-naive patients and 24.2% of TNF-IR patients achieved complete resolution of psoriasis at week 16 (all P < 0.05 vs placebo). Secukinumab effect sizes were generally larger in TNFi-naive vs TNF-IR patients for musculoskeletal and patient-reported domains. Conclusions Secukinumab demonstrated efficacy vs placebo across GRAPPA-OMERACT PsA core domains. Higher responses among TNFi-naive vs TNF-IR patients suggest that secukinumab should be considered for first-line use in PsA. Supplementary Information The online version contains supplementary material available at 10.1007/s40744-021-00337-5. Psoriatic arthritis (PsA) is a long-term disease that can affect a patient’s joints, skin, lower back, physical function, mental health, productivity, and other areas. Drugs called tumor necrosis factor inhibitors (TNFis) can be used to treat PsA, although not all patients benefit from TNFis and many seek other treatment options. These patients, known as TNFi-inadequate responders (TNF-IR), have PsA that is difficult to treat. Another treatment option is secukinumab, a drug that blocks a molecule called interleukin-17 that is involved in PsA. Doctors need to know how different drugs work for treating PsA signs and symptoms in different groups of patients, including TNF-IR patients and those who have never received TNFis (TNFi-naive patients). This study used data from 2049 patients in four different PsA clinical trials (FUTURE 2–5) to see how well secukinumab worked at treating different signs and symptoms of PsA in TNFi-naive and TNF-IR patients. After 16 weeks of treatment, patients who took secukinumab saw greater improvements across all measured PsA signs and symptoms than those who took placebo. This was true for both TNFi-naive and TNF-IR patients. TNFi-naive patients seemed to benefit slightly more than TNF-IR patients—especially in their joint symptoms—although this study was not designed to judge the significance of these differences. These results suggest that secukinumab would be an effective first treatment option for patients with PsA. Since secukinumab improves the skin, joints, and other affected areas, it can be useful in treating the whole patient who has psoriatic disease.

Abstract
OBJECTIVES Physical function is a core outcome in PsA. We examined the construct validity and responsiveness of three commonly used instruments to assess physical function in PsA: HAQ disability index (HAQ-DI), MultiDimensional HAQ (MDHAQ) and the Patient-Reported Outcomes Measurement Information System (PROMIS®) Global-10. METHODS Between 2016 and 2019, patients with PsA were enrolled in the Psoriatic Arthritis Research Consortium longitudinal cohort study in the USA. Correlations were calculated at baseline and among change scores using Spearman's correlation coefficient. Standardized response means were calculated. Agreement with the 20% improvement cut-off was used to determine the potential effect of using MDHAQ or the PROMIS Global-10 physical health (GPH) subscore in place of HAQ-DI when assessing the ACR20. RESULTS A total of 274 patients were included in the analysis. The mean age of patients was 49 years and 51% were male. At baseline, the mean HAQ-DI was 0.6 (s.d. 0.6; range 0-3), the mean MDHAQ was 1.8 (s.d. 1.6; range 0-10) and the mean GPH T-score was 43.4 (s.d. 9.3; range 0-100). All three instruments were strongly correlated at baseline (rho 0.75-0.85). Change scores were moderately correlated (rho 0.42-0.71). Among therapy initiators, the mean change between two visits in HAQ-DI, MDHAQ and GPH was -0.1 (s.d. 0.4), -0.2 (s.d. 1.2) and 2.5 (s.d. 6.1), respectively. The standardized response means were 0.18, 0.16 and 0.41, respectively. CONCLUSION The three instruments tested are not directly interchangeable but have overall similar levels of responsiveness.

Abstract
Introduction The objective of this study is to identify the potential risk factors for progression from subclinical to clinical psoriatic arthritis (PsA). Methods A retrospective, longitudinal, case–control study was conducted at a single hospital, including 25 patients with clinically confirmed PsA in the case group and 137 controls without confirmed PsA. All patients in both groups had a medical history of subclinical PsA. Various baseline covariates were collected from all patients when they had a status of subclinical PsA. Univariate, multivariate, stratified, and interaction analyses were employed to identify potential risk factors of transiting to clinical PsA from subclinical PsA. Results In multivariate logistic regression analysis, older age (OR 10.15, 95% CI 2.79–36.91, p = 0.00), alcohol drinking (OR 3.43, 95% CI 1.17–10.12, p = 0.03), elevated high-sensitivity C-reactive protein (hs-CRP) (OR 1.05, 95% CI 1.01–1.09, p = 0.03) were identified as risk factors for transition from subclinical to clinical PsA. Stratified and logistic regression analyses suggest a significant interaction between age and fatty liver. For patients aged less than 45 years old, the association between fatty liver and clinical PsA was statistically significant. Conclusions Older age, alcohol drinking, elevated hs-CRP, and the presence of fatty liver at less than 45 years old appear to increase the risk of transition from subclinical to clinical PsA. These findings call for a need to manage these risk factors.

Abstract
Psoriatic arthritis (PsA) and ulcerative colitis (UC) are immune-mediated diseases that cause significant burden worldwide. Recent advances in their management have improved patient outcomes. However, significant unmet needs still remain as not all patients respond to current treatments, and patients may lose responsiveness over time. An improved understanding of the pathophysiology of these diseases has brought about the development of novel disease-modifying agents, including interleukin inhibitors and, more recently, Janus kinase (JAK) inhibitors. With the approval of tofacitinib for the treatment of adults with active PsA and in adult patients with moderately-to-severely active UC, JAK inhibitors have recently entered the treatment armamentarium for PsA and UC. A number of other JAK inhibitors are also undergoing clinical development and are currently in phase III trials. This review provides an overview of the current therapeutic options for PsA and UC, with a focus on the JAK inhibitors.

Abstract
Background: The aim of this study is to assess treatment patterns and pharmaco-utilization in patients with psoriatic arthritis (PsA) in Italy.Methods: A retrospective analysis using administrative databases of six Local Health Units was performed. All adult patients with PsA diagnosis and ≥1 prescription for biologic/targeted-synthetic (b/ts) disease-modifying antirheumatic drugs (DMARDs) from January 2010 to March 2017 were included. The date of first b/tsDMARD prescription was defined index-date. Follow-up lasted 1-year post index-date. Patients without b/tsDMARDs prescription pre index-date were defined bionaïve.Results: Of the 1,056 patients included, 33% received adalimumab, 30% etanercept, 10% golimumab, 9% secukinumab, 7% infliximab, 6% ustekinumab, 4% certolizumab, and 1% apremilast. During follow-up, persistence with b/tsDMARDs was observed in 79.8% of patients, 10.8% switched therapies, dose change occurred in 15.8% of patients, 47.4% received an add-on. Among bionaïve patients (n = 591), 67.0% were persistent with b/tsDMARDs, 10.1% switched therapy, 14.5% required a dose change and 45.8% an add-on. Discontinuation was observed in 10.6% of total PsA population and in 24.8% of bionaïve patients.Conclusion: This analysis provided insights on drug utilization patterns for PsA in an Italian real-world setting. Our results show that treatment regimen changes occur in a high proportion of PsA patients.

Abstract
Psoriatic arthritis (PsA) is a complex inflammatory musculoskeletal and skin disease. The treatment of PsA has changed substantially over the past 10 years. Clinical practice guidelines are developed to help busy clinicians rapidly integrate evolving knowledge of therapeutic management into practice. In this review, we compare PsA treatment recommendations or guidelines developed by one national organization [ACR and National Psoriasis Foundation (NPF) in 2018], one regional organization (EULAR in 2015), and one international organization (the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis in 2015). We examine the development of guidelines in PsA more broadly and examine similarities and differences in the three sets of recommendations.

Abstract
OBJECTIVE Therapeutic response was evaluated among new apremilast, methotrexate (MTX), or biologic disease-modifying antirheumatic drug (bDMARD) initiators with oligoarticular psoriatic arthritis (PsA). METHODS Patients with oligoarticular PsA in the Corrona PsA/Spondyloarthritis Registry initiating treatment with apremilast, MTX, or bDMARD, and completing 6-month follow-up were included. RESULTS In total, 150 patients initiated monotherapy (apremilast: n = 34; MTX: n = 15; bDMARD: n = 101). Apremilast initiators had higher baseline disease activity than MTX initiators. At follow-up, apremilast initiators experienced numerically greater disease activity improvements than MTX initiators and similar improvements to bDMARD initiators. CONCLUSION Findings suggest apremilast monotherapy is an effective option for patients with oligoarticular PsA.

Abstract
Psoriatic disease (PsD) is a heterogeneous condition that can affect peripheral and axial joints (arthritis), entheses, skin (psoriasis) and other structures. Over the past decade, considerable advances have been made both in our understanding of the pathogenesis of PsD and in the treatment of its diverse manifestations. However, several major areas of continued unmet need in the care of patients with PsD have been identified. One of these areas is the prediction of poor outcome, notably radiographic outcome in patients with psoriatic arthritis, so that stratified medicine approaches can be taken; another is predicting response to the numerous current and emerging therapies for PsD, so that precision medicine can be applied to rapidly improve clinical outcome and reduce the risk of toxicity. In order to address these needs, novel approaches, including imaging, tissue analysis and the application of proteogenomic technologies, are proposed as methodological solutions that will assist the dissection of the critical immune-metabolic pathways in this complex disease. Learning from advances made in other inflammatory diseases, it is time to address these unmet needs in a multi-centre partnership aimed at improving short-term and long-term outcomes for patients with PsD.

Comparison of remission and low disease activity states with DAPSA, MDA and VLDA in a clinical trial setting in psoriatic arthritis patients: 2-year results from the FUTURE 2 study. Semin Arthritis Rheum 2020; 50:709-718. [PMID: 32521325 DOI: 10.1016/j.semarthrit.2020.03.015] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2019] [Revised: 03/10/2020] [Accepted: 03/16/2020] [Indexed: 01/20/2023]
Abstract
OBJECTIVES Remission (REM) or low disease activity (LDA) states were compared in a clinical trial setting of the FUTURE 2 study (NCT01752634) using Disease Activity Index for Psoriatic Arthritis (DAPSA) and Minimal Disease Activity (MDA) composite indices in secukinumab treated PsA patients. METHODS The proportion of patients reaching DAPSA-REM (cut-off ≤4) or REM+LDA (≤14), and very low disease activity (VLDA; achieving 7/7 criteria) or MDA (≥5/7), were compared in the overall population, by prior use of anti-TNF therapy, and by time since diagnosis using as observed data. The proportion of patients who met individual core component and other variables of interest were also computed to assess residual disease activity in DAPSA-REM/REM+LDA states and VLDA/MDA responses. The relationship between DAPSA/MDA and patient reported outcomes (PROs), including health-related quality of life, physical function, and fatigue were assessed using mixed model for repeated measures. RESULTS More patients could achieve DAPSA-REM or DAPSA-REM+LDA status than VLDA or MDA responses, respectively, at all the time points in the overall population, irrespective of anti‒TNF status and time since diagnosis. Higher proportion of patients reaching DAPSA-REM or VLDA achieved more thresholds of core components (joints, pain, patient and physician global assessments, and function) than DAPSA-REM+LDA or MDA over Week 104. There were differences with numerically higher proportion of patients achieving patient global assessment ≤10 mm and ≤20 mm, and physician global assessment ≤10 mm with MDA than with DAPSA-REM+LDA, and patient pain VAS ≤15 mm, PASI ≤1, HAQ ≤0.5 with VLDA or MDA than with DAPSA-REM or DAPSA-REM+LDA, respectively, through 104 weeks. Improvements in PROs were significantly better for patients in DAPSA-REM+LDA versus DAPSA-moderate+high disease activity status, and for MDA responders versus non-responders. CONCLUSION These analysis add to the evidence that both DAPSA and MDA composite index measures can be used for evaluation of the status and treatment response utilizing a treat to target approach in PsA patients in a clinical trial setting and improve patient health related outcomes.

Abstract
Introduction: Primary endpoints and inclusion/exclusion criteria of biologics and small oral molecules for psoriasis treatment have been evolving due to a better understanding of the pathogenesis and potential risks.Areas covered: We analyzed the designs of key phase 3 pivotal trials of all biologics and small oral molecules approved for moderate to severe plaque psoriasis from published data on the ClinicalTrials.gov website and literature in the PubMed database. Alefacept, efalizumab, anti-tumor necrosis factors, anti-interleukin (IL)-12/IL-23, anti-IL-17 and anti-IL-23 inhibitors were discussed chronologically. Small oral molecules including tofacitinib and apremilast were also reviewed.Expert opinion: The primary endpoints of trials of biologics have been raised progressively and psoriasis area and severity index (PASI) 100 can now be readily achievable by the recent biologics. For safety, 5-year observation periods have become a gold standard after the report of progressive multifocal leukoencephalopathy after efalizumab. Also, the need for tuberculosis (TB) prophylaxis has also been relaxed in one trial of risankizumab. Small oral molecules are the future of affordable effective treatment for psoriasis, but the safety concerns must be overcome as reflected by their more stringent exclusion criteria. More biologic switch data and inclusion of patients previously excluded, e.g. viral hepatitis, are still needed.

Abstract
Objectives Psoriatic arthritis is a chronic inflammatory disease that affects the musculoskeletal system. It can include arthritis, spondylitis, dactylitis and enthesitis, and is strongly associated with the presence of psoriasis. The introduction of biological therapies as a treatment option has brought a significant improvement in disease control for patients with psoriatic arthritis. Here, we aimed to detect emerging differences in demographic and clinical characteristics of the psoriatic arthritis patient study population since the introduction of biologicals. We hypothesised that evolving views on control of disease activity and increased experience in the management of psoriatic arthritis have affected the patient population considered for clinical trials and that this may serve as a proxy for changes in clinical practice. Methods We systematically searched for and selected 12 phase II and phase III trials and divided them into three treatment periods based on different time periods and working mechanisms of the particular biologicals. We made a selection of patient and disease parameters for which data were available in all three periods, calculated those data per period and looked for statistically significant differences between the treatment periods. Results Statistical analysis showed significant differences in patient characteristics, disease characteristics, disease activity, disease effects and use of prior treatments between the patient populations of the three periods. Conclusion This study shows a clear evolution of the patient population considered for clinical trials since the introduction of biologicals. Further research is needed to see if those changes can be detected in the daily clinical practice.

Efficacy and safety of guselkumab in patients with active psoriatic arthritis: a randomised, double-blind, placebo-controlled, phase 2 study. Lancet 2018; 391:2213-2224. [PMID: 29893222 DOI: 10.1016/s0140-6736(18)30952-8] [Citation(s) in RCA: 129] [Impact Index Per Article: 21.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2017] [Revised: 03/26/2018] [Accepted: 04/17/2018] [Indexed: 12/13/2022]
Abstract
BACKGROUND Guselkumab, a human monoclonal antibody that binds to the p19 subunit of interleukin 23, has been approved for the treatment of moderate-to-severe psoriasis. Psoriatic arthritis is a common comorbidity of psoriasis with an umet need for novel treatments. We assessed the efficacy and safety of guselkumab in patients with active psoriatic arthritis. METHODS We did a randomised, double-blind, placebo-controlled, phase 2a trial at 34 rheumatology and dermatology practices in Canada, Germany, Poland, Romania, Russia, Spain, and the USA. Eligible participants were aged 18 years or older with active psoriatic arthritis and plaque psoriasis affecting at least 3% of their body surface area, with three or more of 66 tender joints and three or more of 68 swollen joints, who had an inadequate response or intolerance to standard treatments. We randomly assigned patients (2:1) via a central interactive web-response system using computer-generated permuted blocks with a block size of six, stratified by previous anti-tumour necrosis factor-α use, to receive subcutaneous guselkumab 100 mg or placebo at week 0, week 4, and every 8 weeks thereafter for 24 weeks. Patients, investigators, and site staff were masked to treatment assignment until final database lock at week 56. At week 16, patients with less than 5% improvement in swollen and tender joint counts were eligible for early escape to ustekinumab. At week 24, the remaining placebo-treated patients crossed over to receive guselkumab 100 mg at weeks 24, 28, 36, and 44 and guselkumab-treated patients received a placebo injection at week 24, followed by guselkumab injections at weeks 28, 36, and 44. The primary endpoint was the proportion of patients with at least 20% improvement at week 24 in signs and symptoms of psoriatic arthritis according to American College of Rheumatology criteria (ACR20) in the modified intention-to-treat population (ie, all randomly assigned patients who received at least one dose of study treatment). Safety analyses included patients according to the study drug received. This study is registered with ClinicalTrials.gov, number NCT02319759. FINDINGS Between March 27, 2015, and Jan 17, 2017, we randomly assigned 149 patients to treatment: 100 to guselkumab and 49 to placebo. 17 (35%) of 49 patients in the placebo group and ten (10%) of 100 patients in the guselkumab group were eligible for early escape to ustekinumab at week 16. 29 (59%) of 49 patients in the placebo group crossed over and received guselkumab at week 24. Three (6%) of 49 patients in the placebo group, one (3%) of 29 patients who crossed over from placebo to guselkumab, and six (6%) of 100 patients in the guselkumab group discontinued study treatment before week 44. 58 (58%) of 100 patients in the guselkumab group and nine (18%) of 49 patients in the placebo group achieved an ACR20 response at week 24 (percentage difference 39·7% [95% CI 25·3-54·1]; p<0·0001). Between week 0 and week 24, 36 (36%) of 100 guselkumab-treated patients and 16 (33%) of 49 placebo-treated patients had at least one adverse event. The most frequent adverse event was infection in both groups (16 [16%] of 100 patients in the guselkumab group vs ten [20%] of 49 patients in the placebo group). The prevalence of adverse events between week 0 and week 56 in guselkumab-treated patients (51 [40%] of 129) indicated no disproportional increase with longer guselkumab exposure. No deaths occurred. INTERPRETATION Guselkumab, a novel anti-interleukin 23p19 antibody, significantly improved signs and symptoms of active psoriatic arthritis and was well tolerated during 44 weeks of treatment. The results of this study support further development of guselkumab as a novel and comprehensive treatment in psoriatic arthritis. FUNDING Janssen Research & Development.
