Phase 2 Study of Targeted Treatments for Adults with Moderate to Severe Rheumatoid Arthritis

What this Trial Is About

Researchers are evaluating targeted therapies to treat adults with moderately to severely active Rheumatoid Arthritis RA, a chronic inflammatory condition causing joint pain, stiffness, swelling, and loss of function. This Phase 2 study involves three substudies focusing on different drug treatments to assess their effectiveness and safety for participants who have not responded to one or two prior biologic or targeted synthetic DMARD therapies. Participants will be randomly assigned to receive one of several treatments lutikizumab alone, ravagalimab alone, a combination of lutikizumab and ravagalimab, or matching placebos. These drugs are given by subcutaneous injection. The study involves regular visits at hospitals or clinics where participants receive the assigned treatment and are monitored closely. The treatment period and detailed dosing schedules are part of the studys design. During the trial, participants will undergo medical assessments, blood tests, and questionnaires to monitor treatment effects, side effects, and disease activity. The main outcomes measured include the percentage of participants achieving a 50% improvement according to the American College of Rheumatology criteria by Week 12 and the number of adverse events up to approximately Week 22. Participants will attend regular visits for evaluations throughout the study period, which is expected to complete by November 2027.
