Study to Assess the Safety and Change in Disease Symptoms of Risankizumab (Skyrizi) in Adult Participants With Moderate to Severe Plaque Psoriasis and Psoriatic Arthritis

Plaque Psoriasis is a chronic inflammatory disease in which skin cells build up and develop scaly red and white patches on the skin. 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 will evaluate how safe risankizumab is for the treatment of plaque psoriasis or psoriatic arthritis and to assess change in disease symptoms.

Risankizumab is an approved drug for the treatment of psoriasis and psoriatic arthritis. Around 3000 adult participants with a moderate to severe plaque psoriasis or psoriatic arthritis who had been prescribed risankizumab by their doctor will be enrolled in this study in multiple sites across Korea. The sample size for this study is a requirement by local authorities.

Participants will receive risankizumab prefilled syringe for injection for 52 weeks as prescribed by their physician.

There is expected to be no additional burden for participants in this study. All study visits will occur during routine clinical practice and participants will be followed for 52 weeks.
