What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether sending a short screening questionnaire directly to people with psoriasis can help detect psoriatic arthritis earlier. 18,000 participants will be randomly assigned to receive the questionnaire or not. Those with high scores will be advised to see a rheumatologist. The goal is to see if this direct-to-patient approach leads to more and earlier diagnoses of psoriatic arthritis.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Psoriasis Epidemiology Screening Tool (PEST) questionnaire
What this could lead to
If successful, this approach could help detect psoriatic arthritis earlier in people with psoriasis, potentially leading to faster treatment and better outcomes.
What could go wrong
This is a screening study, not a treatment trial. It may not prove that earlier detection improves long-term health, and the questionnaire might miss some cases or cause unnecessary worry.

The number the study aims to enrol. It can still change while the study runs.
