What this trial studies

This is an observational follow-up of adults with confirmed psoriatic arthritis who begin guselkumab as part of routine clinical care. Participants are enrolled after the treating rheumatologist independently decides to start guselkumab, and inclusion requires PsA diagnosis referenced to the CASPAR criteria and consent under French regulations. The main outcome is treatment persistence over one year, captured from clinical records at scheduled visits. Data are collected at a single participating center (CHU Lille) and no experimental interventions are administered beyond usual care.

Who should consider this trial

Good fit: Adults with a confirmed diagnosis of psoriatic arthritis by a rheumatologist (per CASPAR) who are about to start guselkumab as a first through fourth line bDMARD and who consent to data collection under French requirements.

Not a fit: Patients who are not starting guselkumab, who cannot attend the participating center in Lille, or who do not consent to data collection are not likely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could help clinicians and patients understand real-world treatment retention with guselkumab and inform treatment planning.

How similar studies have performed: Other real-world persistence studies of biologic therapies in psoriatic arthritis have provided useful retention data, but long-term real-world evidence specifically for guselkumab remains relatively limited.

Inclusion criteria:

* 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
* The treatment decision must be taken by the participating rheumatologist prior to, and independently of the patient's inclusion into the study, following clinical practice in accordance with local and overarching guidelines and local regulations
