Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA):updated treatment recommendations for psoriatic arthritis 2021
The state of the art—psoriatic arthritis outcome assessment in clinical trials and daily practice
Psoriatic arthritis is a heterogeneous condition with substantial challenges in optimising outcome measures for both clinical trials and daily practice. As with other inflammatory arthritides, there is no gold standard instrument for measuring disease activity or impact, both of which are key to evaluate therapeutic approaches in trials and monitor disease in daily practice. A wide range of domains have been highlighted in the Outcome Measures in Rheumatology (OMERACT) core domain set for psoriatic arthritis; reflecting the disease involvement in multiple tissues (joints, tendons, skin, and spine) and the heterogenous impact of the disease on individuals. This Review summarises the current evidence around outcome measure selection, considering factors such as unidimensional versus multidimensional outcomes, continuous versus binary measures, and the feasibility of these approaches in trials compared with clinical practice
Psoriasis, psoriatic arthritis, and rheumatoid arthritis: Is all inflammation the same?
AbstractObjectivesTo review the pathophysiology, co-morbidities, and therapeutic options for psoriasis, psoriatic arthritis and rheumatoid arthritis in order to further understand the similarities and differences in treatment paradigms in the management of each disease. New targets for individualized therapeutic decisions are also identified with the aim of improving therapeutic outcome and reducing toxicity.Search strategyUsing the PubMed database, we searched literature published from 2000 to 2015 using combinations of the key words “psoriasis,” “psoriatic arthritis,” “rheumatoid arthritis,” “pathogenesis,” “immunomodulation,” and “treatment.”Inclusion and exclusion criteriaThis was a non-systematic review and there were no formal inclusion and exclusion criteria.Data extractionAbstracts identified in the search were screened for relevance and articles considered appropriate evaluated further. References within these selected articles were also screened. Information was extracted from 198 articles for inclusion in this report.Data synthesisThere was no formal data synthesis. Articles were reviewed and summarized according to disease area (psoriasis, psoriatic arthritis, and rheumatoid arthritis).Headline resultsThe pathophysiology of psoriasis, psoriatic arthritis, and rheumatoid arthritis involves chronic inflammation mediated by pro-inflammatory cytokines. Dysfunction in integrated signaling pathways affecting different constituents of the immune system result in varying clinical features in the three diseases. Co-morbidities, including cardiovascular disease, malignancies, and non-alcoholic fatty liver disease are increased. Increased understanding of the immunopathogenesis allowed development of targeted treatments; however, despite a variety of potentially predictive genetic, protein and cellular biomarkers, there is still significant unmet need in these three inflammatory disorders
Ixekizumab Efficacy and Safety with and without Concomitant Conventional Disease-modifying Antirheumatic Drugs (cDMARDs) in Biologic DMARD (bDMARD)-naive Patients with Active Psoriatic Arthritis (PsA): Results from SPIRIT-P1
Objective: To evaluate the efficacy and safety of ixekizumab alone or with concomitant conventional disease-modifying antirheumatic drugs (cDMARDs) versus placebo in patients with active psoriatic arthritis (PsA) as part of a SPIRIT-P1 subgroup analysis (NCT01695239). Methods: Patients were stratified by cDMARD use (concomitant cDMARDs use (including methotrexate) or none (past or naive use)) and randomly assigned to treatment groups (ixekizumab 80 mg every 4 weeks (IXEQ4W) or every 2 weeks (IXEQ2W) or placebo). Efficacy was evaluated versus placebo at week 24 by the American College of Rheumatology criteria (ACR20/50/70), modified total Sharp score and Health Assessment Questionnaire-Disability Index (HAQ-DI). Safety was assessed according to cDMARD status. Results: Regardless of concomitant cDMARD usage, ACR20, ACR50 and ACR70 response rates were significantly higher versus placebo with IXEQ4W and IXEQ2W. The proportion of patients achieving HAQ-DI minimal clinically important difference was significantly higher versus placebo with IXEQ4W with concomitant cDMARD use and IXEQ2W, regardless of concomitant cDMARD use. Treatment-emergent adverse events (AE) were more frequent versus placebo for either ixekizumab-dosing regimen, regardless of concomitant cDMARD use. Serious AEs were not higher versus placebo, regardless of concomitant cDMARD use. Conclusion: Ixekizumab treatment improved measures of disease activity and physical function in patients with active PsA relative to placebo, when used with or without concomitant cDMARD therapy
Prediction and benefits of minimal disease activity in patients with psoriatic arthritis and active skin disease in the ADEPT trial
Objectives: To determine the proportion of patients with psoriatic arthritis in the Adalimumab Effectiveness in Psoriatic Arthritis trial achieving minimal disease activity (MDA) and its individual components at 1 or more visits over 144 weeks, identify baseline predictors of MDA achievement, and evaluate the association of MDA status with independent quality of life (QoL)-related patient-reported outcomes (PROs).
Methods: Univariate and multivariate analyses were used to identify the baseline characteristics that predicted achievement of MDA at individual time points (weeks 12 through 144) or sustained MDA (achievement of MDA at 2 consecutive time points 12 weeks apart). The association of independent QoL-related PROs with MDA achievement was evaluated at weeks 24 and 144.
Results: In univariate analyses, higher baseline patient assessment of pain, tender joint count (TJC), enthesitis and Health Assessment Questionnaire-Disability Index (HAQ-DI) score were significantly associated with lower likelihood of achieving MDA at later time points. Multivariate analyses confirmed higher baseline HAQ-DI as a significant predictor for failure to achieve MDA at later time points. Achievement of sustained MDA was associated with lower baseline TJC and HAQ-DI score. Achievement of different MDA components appeared to be treatment dependent. MDA achievers had significantly better QoL-related PROs and greater improvements in PROs from baseline to week 24 compared with non-achievers.
Conclusions: Higher HAQ-DI score was the most consistent baseline factor that decreased the likelihood of achieving MDA and sustained MDA at later time points. Achieving MDA was associated with better independent QoL-related PROs
Treat-to-target in PsA: methods and necessity
© Author(s) (or their employer(s)) 2020. Re-use permitted under CC BY-NC. No commercial re-use. See rights and permissions. Published by BMJ. With increasing recognition of the high burden and impact of psoriatic arthritis (PsA) and the growing number of therapeutic options, there has been an intensifying focus on treatment strategy in recent years. In 2015, the Tight Control of Psoriatic Arthritis study confirmed the clinical benefit of using a treat-to-target approach in PsA. This randomised controlled trial found benefits in both arthritis and psoriasis disease activity as well as lower disease impact reported by patients, although participants allocated to tight control experienced a higher rate of serious adverse events. European and international recommendations support the use of a treat-to-target approach in PsA and have offered specific advice on how to do this using outcomes such as the minimal disease activity criteria. However, implementation of this approach in routine practice is low, with real-world data highlighting undertreatment as a result. Recent qualitative work with physicians in the UK has helped researchers to understand the barriers to implementation of treat-to-target in PsA. We now need to address these barriers, provide education and support to non-specialist clinicians in routine practice, and aid the translation of optimal care to the clinic
Inhibition of interleukin-17 in patients with oligoarticular psoriatic arthritis
Introduction: This study evaluated the efficacy of the interleukin-17A inhibitor secukinumab in patients with oligoarticular psoriatic arthritis (PsA).
Methods: A total of 84 patients with oligoarticular PsA, defined as 1–4 tender joints and 1–4 swollen joints, were pooled from the FUTURE 2–5 and MAXIMISE trials (NCT01752634, NCT01989468, NCT02294227, NCT02404350, and NCT02721966). Patients were grouped by treatment received at week 12 (secukinumab 300 mg, secukinumab 150 mg, or placebo) and week 52 (any secukinumab 300 mg or any secukinumab 150 mg). Efficacy was assessed by the proportion of patients achieving selected clinical outcomes. The predictors of Disease Activity index for Psoriatic Arthritis (DAPSA) responses at weeks 12 and 52 were identified by logistic regression analysis.
Results: Secukinumab treatment resulted in greater achievement of DAPSA-based low disease activity (LDA), DAPSA-based remission (REM), DAPSA50, and DAPSA75 than placebo at week 12, with improvements sustained or further increased through week 52. LDA or REM was achieved at week 52 by more than 90% of patients who received either secukinumab dose, although secukinumab 300 mg resulted in the highest achievement of the stringent DAPSA75 and DAPSA REM outcomes. At week 12, younger age was associated with DAPSA LDA or REM and DAPSA50, while lower baseline swollen joint count was associated with DAPSA REM. No predictors were identified at week 52. The safety profile was consistent with the full study populations.
Conclusion: Secukinumab demonstrated efficacy vs placebo across several outcome measures in patients with oligoarticular PsA at week 12, with sustained or improved responses through week 52
