Psoriatic arthritis (PsA) is a long-lasting inflammatory condition that affects the joints and skin in people with psoriasis (PsO). This research aims to evaluate how well the drug zasocitinib (TAK-279) works in adults with active PsA who have not previously used biologic disease-modifying antirheumatic drugs. The study is a Phase 3 clinical trial designed to compare zasocitinib against an active comparator and placebo in this patient group. Participants will receive treatment with either zasocitinib tablets, an active comparator capsule, or a matching placebo. The study includes multiple groups to assess the effects of these treatments. Participants will be followed and treated for up to 60 weeks during the study period. During the study, participants will undergo assessments to measure the percentage achieving improvement according to the American College of Rheumatology 20 (ACR20) response at 16 weeks. Researchers will monitor symptoms, joint and skin involvement, and overall safety throughout the trial. Participants will have regular visits for evaluations and will be observed for treatment effects and any side effects over the full course of the study.
