Phase 3 Study of Sonelokimab Compared to Placebo and Risankizumab in Adults With Active Psoriatic Arthritis Who Did Not Respond Well to Anti-TNF Treatment

What this Trial Is About

Researchers are evaluating sonelokimab in adults with active psoriatic arthritis who have not had adequate results or could not tolerate prior anti-tumor necrosis factor TNF alpha therapy. This Phase 3, multicenter, randomized, double-blind study compares the safety and effectiveness of two doses of sonelokimab against placebo and an active reference treatment called risankizumab. Participants are randomly assigned to one of four groups one receiving sonelokimab dose 1, another receiving sonelokimab dose 2, one receiving placebo, and one receiving risankizumab. Those in the sonelokimab groups receive four initial subcutaneous doses as induction, then maintenance doses every four weeks starting at Week 8. The placebo and risankizumab groups receive their respective treatments subcutaneously according to the study protocol. During the study, participants will undergo assessments of joint tenderness and swelling, skin psoriasis activity, physical function, and quality of life at Week 16. Researchers will monitor response rates based on improvement criteria such as the American College of Rheumatology 50% improvement ACR50. Safety and tolerability will also be followed throughout the trial, which is expected to complete by January 2027.
