ObjectiveTo identify a core set of domains (outcomes) to be measured in psoriatic arthritis (PsA) clinical trials that represent both patients' and physicians' priorities.MethodsWe conducted (1) a systematic literature review (SLR) of domains assessed in PsA; (2) international focus groups to identify domains important to people with PsA; (3) two international surveys with patients and physicians to prioritise domains; (4) an international face-to-face meeting with patients and physicians using the nominal group technique method to agree on the most important domains; and (5) presentation and votes at the Outcome Measures in Rheumatology (OMERACT) conference in May 2016. All phases were performed in collaboration with patient research partners.ResultsWe identified 39 unique domains through the SLR (24 domains) and international focus groups (34 domains). 50 patients and 75 physicians rated domain importance. During the March 2016 consensus meeting, 12 patients and 12 physicians agreed on 10 candidate domains. Then, 49 patients and 71 physicians rated these domains' importance. Five were important to >70% of both groups: musculoskeletal disease activity, skin disease activity, structural damage, pain and physical function. Fatigue and participation were important to >70% of patients. Patient global and systemic inflammation were important to >70% of physicians. The updated PsA core domain set endorsed by 90% of OMERACT 2016 participants includes musculoskeletal disease activity, skin disease activity, pain, patient global, physical function, health-related quality of life, fatigue and systemic inflammation.ConclusionsThe updated PsA core domain set incorporates patients' and physicians' priorities and evolving PsA research. Next steps include identifying outcome measures that adequately assess these domains.
BackgroundUpadacitinib is a Janus kinase inhibitor under evaluation for the treatment of psoriatic arthritis (PsA). We evaluated upadacitinib in patients with PsA and prior inadequate response or intolerance to at least one biologic disease-modifying antirheumatic drug (DMARD).MethodsIn this 24-week randomised, placebo-controlled, double-blind, phase 3 trial, 642 patients were randomised (2:2:1:1) to once per day upadacitinib 15 mg or 30 mg, placebo followed by upadacitinib 15 mg or placebo followed by upadacitinib 30 mg at week 24. The primary endpoint was the proportion of patients achieving American College of Rheumatology (ACR) 20 response at week 12. Achievement of minimal disease activity (MDA) was assessed at week 24. Treatment-emergent adverse events are reported for all patients who received at least one dose of trial drug.ResultsAt week 12, significantly more patients receiving upadacitinib 15 mg and 30 mg versus placebo achieved ACR20 (56.9% and 63.8% vs 24.1%; p<0.001 for both comparisons). At week 24, MDA was achieved by more upadacitinib 15 mg-treated (25.1%) and 30 mg-treated patients (28.9%) versus placebo (2.8%; p<0.001 for both comparisons). Generally, the rates of treatment-emergent adverse events were similar with placebo and upadacitinib 15 mg and higher with upadacitinib 30 mg at week 24. Rates of serious infections were 0.5%, 0.5% and 2.8% with placebo, upadacitinib 15 mg and upadacitinib 30 mg, respectively.ConclusionIn this trial of patients with active PsA who had inadequate response or intolerance to at least one biologic DMARD, upadacitinib 15 mg and 30 mg was more effective than placebo over 24 weeks in improving signs and symptoms of PsA.Clinical trial registration numberNCT03104374
Disability at work in those with PsA is high; however, data on its associations are limited by the small number of reports and heterogeneity of data collected. Future work should focus on the validation of WD data collection tools for use in PsA.
Smoking, delay to diagnosis, older age at diagnosis, female sex and a history of anti-TNF treatment are associated with worse physical function in established PsA.
Our study demonstrates that the feasibility, specificity, and sensitivity of the CASPAR are maintained when adapted for retrospective use to classify an established research cohort.
Objectives
The current psoriatic arthritis (PsA) Core Domain Set defines core
domains to be measured in randomized controlled trials (RCTs) and
longitudinal observational studies (LOS) and was published in 2006. At the
Outcome Measures in Rheumatology (OMERACT) meeting in 2014, researchers,
clinicians and patients unanimously voted for updating the PsA Core Domain
Set to include the patient perspective in accordance with OMERACT Filter
2.0. Herein we report the proceedings of the PsA Workshop at the OMERACT
meeting in 2016 including studies presented in the plenary, results of
breakout group discussions, and final voting and endorsement of the 2016
updated PsA Core Domain Set.
Methods
We conducted research to develop the updated PsA Core Domain Set. At
OMERACT 2016 this work was presented, discussed in breakout groups and the
updated PsA core domain set was voted on and endorsed by OMERACT
participants.
Results
The updated PsA Core Domain Set includes: musculoskeletal disease
activity, skin disease activity, fatigue, pain, patient global, physical
function, health related quality of life and systemic inflammation which are
recommended for all RCTs and LOS). Economic cost, emotional well-being,
participation and structural damage are important but not required in all
RCTs and LOS. Independence, sleep, stiffness and treatment burden on the
research agenda.
Conclusion
The updated PsA Core Domain Set was endorsed at OMERACT 2016. Next
steps for the PsA working group include evaluation of available outcome
measures for each of the core domains and development of a PsA core outcome
measurement set.
Consensus was not reached on a continuous measure of disease activity. In the interim, the group recommended several composites. Consensus was reached on a treatment target of VLDA/MDA. An extensive research agenda was composed and recommends that data on all PsA clinical domains be collected in ongoing studies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
