Researchers are evaluating the effectiveness of icotrokinra JNJ-77242113 compared to a placebo in adults with active psoriatic arthritis PsA, including those who have and have not previously used biologic treatments. The study aims to assess how well icotrokinra reduces the signs and symptoms of PsA, focusing on improvements measured by the American College of Rheumatology ACR 20 response at Week 16. Participants are randomly assigned to receive one of two doses of icotrokinra or a matching placebo. Those initially receiving placebo will switch to one of the icotrokinra doses at Week 16. Participants who continue without discontinuing the study drug are eligible to enter a long-term extension phase, where they keep receiving their assigned icotrokinra dose. The treatment period involves regular monitoring and assessment of psoriatic arthritis symptoms. Throughout the study, participants will undergo various assessments, including evaluations of joint swelling and tenderness, skin psoriasis severity, fatigue, physical function, and quality of life. Laboratory tests such as C-reactive protein levels will be measured to monitor inflammation. Researchers will track responses using validated scales like the Psoriatic Area and Severity Index PASI and Investigator Global Assessment IGA. The total duration includes treatment and follow-up visits up to Week 16, with options for extended treatment in the long-term extension phase.

Researchers are studying the drug JNJ-88545223 to see how well it works compared with a placebo in adults who have active psoriatic arthritis PsA. This study aims to determine if JNJ-88545223 can reduce the signs and symptoms of PsA and improve the health of joints and skin. The trial is a randomized, double-blind phase 2b study designed to evaluate different doses of the drug. Participants will be randomly assigned to receive one of four treatments from Week 0 to Week 16 placebo, or one of three doses of JNJ-88545223. Each group will receive their assigned treatment under blinded conditions to compare the effects. The study focuses on evaluating the efficacy and safety of these doses over the 16-week treatment period. During the study, participants will undergo regular assessments to measure treatment effects, including the American College of Rheumatology ACR 50 response at Week 16 as the primary outcome. Additional evaluations include skin severity indexes PASI responses, physical function questionnaires, and quality of life surveys. Safety and symptoms will be monitored throughout the trial, which lasts approximately 16 weeks for each participant.
