This clinical trial is focused on studying the effects of a new treatment for Rheumatoid Arthritis, a condition that causes pain and swelling in the joints. The treatment being tested is called Peresolimab (also known by its code name LY3462817), which is a type of medication known as a humanised IgG1 monoclonal antibody against PD-1. This medication is designed to help the immune system work better in managing the symptoms of rheumatoid arthritis. In this study, some participants will receive Peresolimab, while others will receive a placebo, which is a substance with no active medication.
The purpose of the study is to evaluate how effective Peresolimab is compared to a placebo in improving the symptoms of rheumatoid arthritis. Participants in the study will receive the treatment through a solution for infusion, which means the medication is given directly into the bloodstream. The study will last for a period of time, during which participants will be monitored to see how their symptoms change. The goal is to see if Peresolimab can help achieve a 20% improvement in symptoms, as defined by the American College of Rheumatology (ACR)20 criteria.
Throughout the study, participants will be closely observed to ensure their safety and to gather information on how well the treatment works. The study is designed to provide valuable insights into the potential benefits of Peresolimab for people living with rheumatoid arthritis, with the hope of offering a new option for managing this challenging condition.
