Abstract The concept of psoriatic arthritis (PsA) prevention is gaining increased interest owing to the physical limitation, poor quality of life and low remission rates that are achieved with current therapies for PsA. The psoriasis-to-PsA transition offers a unique opportunity to identify individuals at increased risk of developing PsA and to implement preventive strategies. However, identifying individuals at increased risk of developing PsA is challenging as there is no consensus on how this population should be defined. This Consensus Statement puts forward recommended terminology from the Psoriasis and Psoriatic Arthritis Clinics Multicenter Advancement Network (PPACMAN) for defining specific subgroups of individuals during the preclinical and early clinical phases of PsA to be used in research studies. Following a three-round Delphi process, consensus was reached for three terms and definitions: ‘increased risk for PsA’, ‘psoriasis with asymptomatic synovio-entheseal imaging abnormalities’ and ‘psoriasis with musculoskeletal symptoms not explained by other diagnosis’. These terms and their definitions will enable improved identification and standardization of study populations in clinical research. In the future, as increasing evidence emerges regarding the molecular and clinical features of the psoriasis-to-PsA continuum, these terms and definitions will be further refined and updated.
Objective To evaluate secukinumab (SEC) 300 mg and 150 mg vs placebo in a United States–only population of biologic-naïve patients with psoriatic arthritis (PsA). Methods CHOICE was a double-blind, randomized controlled trial conducted in the US. Biologic-naïve patients with PsA and psoriasis (PsO) were randomized 2:2:1 to SEC 300 mg (n = 103), SEC 150 mg (n = 103), or placebo (n = 52). The primary objective was to show superiority of SEC 300 mg vs placebo in American College of Rheumatology 20% (ACR20) response at week 16. Additional objectives included the effect of SEC on dactylitis, enthesitis, PsO, and safety. Results ACR20 response rates at week 16 were higher with SEC 300 mg than with placebo (51.5% vs 23.1%; odds ratio 3.51 [95% CI 1.65-7.45]; P = 0.001). SEC 300 mg also led to greater ACR50/70 responses and improvements in other variables vs placebo. Responses were generally sustained over time. Patients with inadequate response to SEC 150 mg at weeks 16, 28, or 40 who received dose escalation to 300 mg experienced improved clinical response after uptitration. The most common adverse events were upper respiratory tract infections and diarrhea. No inflammatory bowel disease was reported or new safety signals observed. Conclusion SEC 300 mg led to rapid and significant improvements over placebo in symptoms of PsA in this heavier population of US-only, biologic-naïve patients. Findings were consistent with previous studies and suggest that SEC 300 mg is a safe and efficacious first-line biologic treatment for patients with PsA. [ClinicalTrials.gov: NCT02798211 ]
Background Pain is a core domain of psoriatic arthritis (PsA). This post hoc analysis evaluated time to pain improvement and the impact of baseline pain severity on pain response in patients with PsA receiving tofacitinib. Methods Data from two trials ( NCT01877668 ; NCT01882439 ) in patients receiving tofacitinib 5 mg twice daily, placebo switching to tofacitinib 5 mg twice daily at month 3 (placebo-to-tofacitinib) or adalimumab ( NCT01877668 only) were included. Improvement in pain (≥30%/≥50% decrease from baseline in Visual Analogue Scale pain score) was assessed; median time to initial (first post-baseline visit)/continued (first two consecutive post-baseline visits) pain improvement was estimated (Kaplan-Meier) for all treatment arms. A parametric model was used to determine the relationship between baseline pain severity and time to pain response in patients receiving tofacitinib. Results At month 3, more patients experienced pain improvements with tofacitinib/adalimumab versus placebo. Median days (95% CI) to initial/continued pain improvements of ≥30% and ≥50%, respectively, were 55 (29–57)/60 (57–85) and 85 (57–92)/171 (90–not estimable (NE)) for tofacitinib, versus 106 (64–115)/126 (113–173) and 169 (120–189)/NE (247–NE) for placebo-to-tofacitinib. Pain improvements were also experienced more quickly for adalimumab versus placebo. Predicted time to ≥30%/≥50% pain improvement was shorter in patients with higher baseline pain versus lower baseline pain (tofacitinib arm only). Conclusions In patients with PsA, pain improvements were experienced by more patients, and more rapidly, with tofacitinib and adalimumab versus placebo. In those receiving tofacitinib, higher baseline pain was associated with faster pain improvements.
Axial spondyloarthritis (AxSpA) is a chronic inflammatory musculoskeletal condition that involves the axial joints but is also associated with peripheral arthritis, enthesitis, and dactylitis. In the past ten to fifteen years, we have seen numerous advances in AxSpA, including new therapies for the condition and a new name. Previously known as ankylosing spondylitis (AS), the name change to AxSpA reflects the spectrum of disease that includes both nonradiographic and radiographic disease. Since the first version of AxSpA criteria in 2009 that allowed for the opportunity to have AxSpA without radiographic damage, we have learned a great deal about this disease subset, including the risk for progression. Beyond the change from AS to AxSpA, the larger group of disorders, previously referred to as “seronegative spondyloarthropathy,” is now known simply as spondyloarthritis, a change adopted by both the European Alliance of Associations for Rheumatology and the American College of Rheumatology in the past ten years. In this chapter, we will describe advances in AxSpA over the past approximately ten years and how they have shaped our view of AxSpA in 2021. Furthermore, we will speculate where we are heading in the next ten years.
At the 2020 annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA), the International Dermatology Outcome Measures (IDEOM) Initiative Psoriasis (PsO) Working Group presented an update on its work to agree on meaningful, valid, and feasible outcome measures for PsO randomized controlled trials and longitudinal observational studies. The Treatment Satisfaction Working Group presented the development of a treatment satisfaction instrument to be utilized in PsO clinical trials. The Musculoskeletal Symptoms Working Group presented an overview of their work conducted to date to define how to best measure musculoskeletal symptoms in PsO clinical studies, and discussed next steps during an open-panel discussion, which included PsO and psoriatic arthritis experts.
There is limited evidence on the clinical and economic benefit of achieving disease control in psoriatic arthritis (PsA) and ankylosing spondylitis (AS), thus we aimed to assess the impact of disease control on healthcare resource use (HCRU) and direct medical costs among US patients with PsA or AS over 1 year.Data were derived from the US OM1 PsA/AS registries (PsA: 1/2013-12/2020; AS: 01/2013-4/2021) and the Optum Insight Clinformatics® Data Mart to identify adult patients with PsA or AS. Two cohorts were created: with disease control and without disease control. Disease control was defined as modified Disease Activity Index for Psoriatic Arthritis (DAPSA28) ≤ 4 for PsA and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) < 4 for AS. Outcomes were all-cause inpatient, outpatient, and emergency department (ED) visits and associated costs over a 1-year follow-up period. Mean costs per person per year (PPPY) were assessed descriptively and adjusted odds ratios (aOR) with 95% confidence intervals (CI) were estimated for the likelihood of HCRU by logistic regression.The study included 1235 PsA (with disease control: N = 217; without: N = 1018) and 581 AS patients (with disease control: N = 342; without: N = 239). Patients without disease control were more likely to have an inpatient (aOR [95% CI]; PsA: 3.0 [0.9, 10.1]; AS: 7.7 [2.3, 25.1]) or ED (PsA: 1.6 [0.6, 4.2]; AS: 3.5 [1.5, 8.3]) visit than those with disease control. Those without disease control, vs. those with disease control, had greater PPPY costs associated with inpatient (PsA: $1550 vs. $443), outpatient (PsA: $1789 vs. $1327; AS: $2498 vs. $2023), and ED (PsA: $114 vs. $57; AS: $316 vs. $50) visits.Findings from this study demonstrate lower disease activity among patients with PsA and AS is associated with less HCRU and lower costs over the following year.
