Summary

This trial aims to see if bimekizumab works better than risankizumab in treating active psoriatic arthritis after 16 weeks of treatment.

Who is the study for?
This trial is for adults with active Psoriatic Arthritis diagnosed at least 6 months ago, who have not responded well to or tolerated previous treatments. Participants must have at least 3 tender and swollen joints and one psoriatic skin lesion or a history of plaque-type psoriasis.
What is being tested?
The study aims to compare the effectiveness of two drugs, Bimekizumab and Risankizumab, over a period of 16 weeks in treating Psoriatic Arthritis. Some participants will receive a placebo instead as part of the control group.
What are the potential side effects?
Potential side effects may include reactions at the injection site, increased risk of infections due to immune system suppression, headaches, fatigue, and possible allergic reactions.
