Outcome Measures
Primary Outcomes (3)
Proportion of Participants Still Receiving Treatment at 1 Year
Discontinuation or maintenance of guselkumab treatment will be recorded by the physician at each visit. Proportion of participants still receiving treatment will be reported in the outcome measure.
At 1 year
Percentage of Participants Still Receiving Treatment at Persistence Time
Persistence time of the initial treatment: defined as the time from the date of the first administration of guselkumab to the date that the last dose of guselkumab treatment was administered plus 1 dosing interval (8 weeks), or until start of subsequent treatment.
Up to 8 weeks
Number of Participants Starting New Treatment
Participants starting new treatment along with reason of discontinuation will be reported.
At 1 year

Study Arms (1)
Group 1: Psoriatic Arthritis Participants Treated With Guselkumab
Participants with confirmed diagnosis of psoriatic arthritis treated with guselkumab as per routine clinical practice will be enrolled. No drug will be provided as part of this study. Only data available within routine clinical practice will be collected in this study.
Eligibility Criteria
The study population will include participants affected with psoriatic arthritis (PsA) according to classification for psoriatic arthritis (CASPAR) criteria.
You may qualify if:
- Have a confirmed diagnosis of psoriatic arthritis (PsA) as determined by a rheumatologist with reference to ClASsification criteria for Psoriatic ARthritis (CASPAR)
- Start guselkumab as a first, second, third, or fourth line of disease-modifying antirheumatic drug (bDMARD) therapy for the indication of PsA as part of standard clinical practice at the time of enrollment into the observational study
- Initiating guselkumab treatment according to Summary of Product Characteristics (SmPC) indication
- Must have received the information note, given his/her oral agreement and has not objected to the collection of his/her data in accordance with French requirements
You may not qualify if:
- Have already taken a specific interleukin-23 inhibitor (IL-23i) treatment.
- Are receiving combination therapy: 2 or more targeted therapies (biotherapy, Janus kinase \[JAK\] inhibitor, phosphodiesterase 4 (PDE4) inhibitor) indicated for PsA/PsO at the same time
- Has a contra-indication to guselkumab according to the SmPC (for hypersensitivity or due to active clinically important infection, example active tuberculosis)
- Unwilling or unable to participate in long-term data collection
- Received an investigational drug (including investigational vaccines) or used an invasive investigational medical device within 30 days before the start of the study ( that is, signing of informed consent)
- Currently enrolled in any interventional study or any Janssen-Cilag France-sponsored observational clinical study
- Is under guardianship or curatorship, judicial protection, future protection mandate or under family authorization
