Study population

Participants with a confirmed diagnosis of Psoriatic Arthritis (PsA) according to the clinical practice and for which a treatment with ustekinumab is indicated as a first (biological-naïve participants) or a second line (biological-experienced participants) of biological disease-modifying antirheumatic drugs (bDMARD) for PsA / psoriasis (PsO) will be observed depending on whether their disease is managed by a dermatologist or by a rheumatologist in routine practice.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Participant with a confirmed diagnosis of Psoriatic Arthritis (PsA) according to the dermatological and/or rheumatologic routine practice, using different diagnosis tools, example, the Classification criteria for Psoriatic Arthritis (CASPAR), or others
  • Participant must be starting ustekinumab for PsA according to the local labelling, as a first (biological naïve participant), or (biological experienced participants) of bDMARD therapy: First line bDMARD therapy: The first line therapy includes all bio-naïve participants who start their ustekinumab as their first biologic treatment at the study start (within a maximum 1-month window after the baseline visit); Second line bDMARD therapy: The second line therapy includes participants who initiated ustekinumab as their second biologic therapy at the study start (within a maximum 1-month window after the baseline visit)
  • Participant for which the ustekinumab treatment has been decided by the investigator prior to and independently of the participant's inclusion into the study
  • Participant for which the first administration of the ustekinumab treatment will occur within the 4-week period from inclusion assessment
  • Participant has signed an form

Exclusion criteria

Exclusion Criteria:

  • Participant starting ustekinumab as a third or further line of bDMARD therapy
  • Already ustekinumab-experienced participants
  • Participant has received an drug (including investigational vaccines) or used an invasive investigational medical device within at least 30 days before the start of the study or more according to the half-life of the investigational drug
  • Participant has refused to participate in the study or unable to give his consent
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

It consists of 6 questions: fatigue, spinal pain, arthralgia (joint pain) or swelling, enthesitis (inflammation of tendons and ligaments), and morning stiffness (2 questions: duration and severity). Each question is an easy to answer 10 centimeter (cm) visual analog scale (VAS), with 0 being none, and 10 being very severe. In order to give each of the 5 symptoms equal weight, the mean of the 2 questions about morning stiffness will be added to the total of the remaining 4 scores, and the final BASDAI score (ranging 0-10) is the average of the overall total score. Higher BASDAI score indicates more severe AS symptom.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2017 to primary completion in Apr 2020, 35 months.

Of 52 industry-sponsored observational studies under Arthritis, Psoriatic, half reached primary completion within 47 months of starting (the median), counting those still running; a quarter within 32 and three quarters within 63. This study's 35 months is below that.

Counting every sponsor, half of 128 studies reached it within 47 months; a quarter within 28 and three quarters within 83.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 3, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
