Trial summary

Psoriatic arthritis (PsA) is one of the most common comorbidities in patients with psoriasis (PsO). Current research suggests that the progression from PsO to PsA can be divided into five stages of the disease: PsO, preclinical PsA, subclinical PsA, prodromal PsA, and clinical PsA.

About this study

Official title: Effectiveness of Biologics on Synovitis and Enthesitis Using Musculoskeletal Ultrasound Assessment in Subclinical Psoriatic Arthritis: a 12-week Observational Real-world Study

Psoriatic arthritis (PsA) is one of the most common comorbidities in patients with psoriasis (PsO). Current research suggests that the progression from PsO to PsA can be divided into five stages of the disease: PsO, preclinical PsA, subclinical PsA, prodromal PsA, and clinical PsA. Subclinical PsA refers to psoriasis participants who do not exhibit any clinical symptoms of arthritis but show evidence of synovio-enthesitis on ultrasound (US). However, there is currently no definitive biomarker that can accurately predict the progression from PsO to PsA. Synovitis and enthesitis are considered important features of PsA. Musculoskeletal ultrasound, using B-mode ultrasound and power Doppler (PD), can visualize synovitis and enthesitis, allowing for the early detection of subclinical PsA, as confirmed by multiple studies. Biologics are currently widely used in the treatment of PsA, with current treatment interventions primarily focusing on patients already diagnosed with PsA. In this study, we conducted a rigorous screening process to identify potential subclinical PsA patients among those with moderate to severe psoriasis. We treated these subclinical PsA patients with biologics and used musculoskeletal ultrasound as a method of efficacy assessment to observe the improvement of synovitis and enthesitis in subclinical PsA patients after 12 weeks of treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Improvement of synovitis and enthesitis after 12 weeks of treatment with biological agents.

    The assessment using ultrasound was performed at two time points: baseline (0 weeks) and 12 weeks after medication initiation. The joint examination sites were based on the PsAson22. The examination sites for enthesitis were based on the Leeds Enthesitis Index (LEI). According to the European League Against Rheumatism (EULAR)- the Outcome Measures in Rheumatology (OMERACT) definition, the 22 joints with synovitis were scored using ultrasound composite semi-quantitative scale. Additionally, the 6 sites of entheses were evaluated according to the OMERACT enthesitis composite semi-quantitative scale. When assessing joint synovitis and enthesitis using grey scale (GS) and power Doppler (PD), we take the higher score as the final score for that site (range 0 to 3). The total score is the sum of the scores for each site, ranging from 0 to 84.

    Assess the improvement of Sub-PsA patients by evaluating changes before and after treatment through the scoring of synovitis and enthesitis.

    Measured: From enrollment to the end of treatment at 12 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Subclinical Psoriatic Arthritis, run by Chao Ji at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 25 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvement of synovitis and enthesitis after 12 weeks of treatment with biological agents. (time frame: From enrollment to the end of treatment at 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2025.
