Psoriatic arthritis (PsA) is a type of arthritis (swelling and stiffness in the joints) that is frequently seen in trial participants who also have the skin condition psoriasis. It is caused by an overactive immune system where the body attacks healthy tissue by mistake. This study aims to describe the long term usage and effectiveness with risankizumab (RZB) relative to other advanced therapeutic options for the management of PsA in daily clinical practice.

Risankizumab is an approved drug for the treatment of psoriatic arthritis. The study will not be conducted in the United States, however it will be conducted in approximately 15 countries and include at least 900 and up to 1200 participants with a 2 to1 ratio of participant allocation between participants receiving risankizumab and participants receiving other advanced therapeutic agents.

The therapy is prescribed in the usual manner in accordance with the terms of the local marketing authorization and professional and reimbursement guidelines with regards to dose, population, and indication. All study visits will occur during routine clinical practice and participants will be followed for 24 months.

There is expected to be no additional burden for participants in this study.

• Participant must have demonstrated an inadequate response to at least 1 Disease-modifying antirheumatic drug (DMARD) (with max 50% Biologic DMARD-Inadequate Response); alternatively, participant must have demonstrated an intolerance to or contraindication for csDMARDs as determined by the investigator.
