Researchers are investigating targeted therapies to treat adults with moderately to severely active Rheumatoid Arthritis (RA), a chronic inflammatory disease that causes pain, stiffness, swelling, and loss of joint function. This Phase 2 study includes three substudies that evaluate different treatments for participants who have not responded well to one or two prior biologic or targeted synthetic disease-modifying antirheumatic drug (tsDMARD) therapies. The study aims to assess both the effectiveness and safety of these therapies. The study tests three treatment approaches: lutikizumab alone, ravagalimab alone, and a combination of lutikizumab and ravagalimab, each compared against placebo. All treatments are given by subcutaneous injection. About 180 participants will be enrolled across approximately 65 sites worldwide. Participants must be on a stable dose of methotrexate to join the study. The study requires regular visits to hospitals or clinics for treatment and monitoring. During the study, participants will undergo medical assessments, blood tests, and questionnaires to monitor treatment effects and side effects. The main outcomes measured include the percentage of participants achieving a 50% improvement in Rheumatoid Arthritis symptoms by week 12 and the number of participants experiencing adverse events up to about week 22. Participants may have a higher treatment burden than usual care due to the study procedures and visits.

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.

Psoriatic arthritis is a condition where the immune system attacks healthy cells causing joint pain, swelling, and stiffness that can worsen and improve over time. The trial is a Phase 2 study designed to evaluate the safety and effectiveness of targeted therapies in adults with active psoriatic arthritis, focusing on changes in disease symptoms. The therapies studied are risankizumab and lutikizumab, and the study involves multiple substudies to assess these treatments.
