Used in the treatment of autoimmune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis. It works by blocking the interleukin-6 receptor (IL-6R), reducing inflammation and immune system overactivity. This antibody helps decrease disease activity, improve clinical symptoms, and prevent joint and organ damage in chronic inflammatory conditions. It is developed as a therapeutic candidate for patients who do not respond adequately to standard treatments.
