Researchers are evaluating the effectiveness and safety of sonelokimab compared with placebo in adults with active psoriatic arthritis who have not responded well or could not tolerate anti-tumor necrosis factor alpha (TNFb1) therapy. This Phase 3, randomized, double-blind study also includes risankizumab as an active reference treatment to better understand the benefits and risks of sonelokimab for this condition. Participants will be randomly assigned to one of four groups receiving either sonelokimab at doses of 60 mg or 120 mg, placebo, or risankizumab. The treatments are given by injection under the skin. The study is conducted across multiple centers and compares the response rates after 16 weeks of treatment to evaluate improvement in psoriatic arthritis symptoms. During the trial, participants will undergo joint assessments, blood tests for specific antibodies, and evaluations of skin psoriasis. Researchers will monitor how many participants achieve at least a 50% improvement in arthritis criteria compared to placebo. Safety and side effects will be closely observed throughout the study. The total time involved includes screening, treatment, and follow-up visits to ensure thorough evaluation of both effectiveness and safety.
