How Does It Work?Arcalyst works by blocking the actions of interleukin-1 beta (IL-1β), a protein of the immune system that causes inflammation in the body. People with CAPS have increased levels of IL-1β, which leads to inflammation in the body. By blocking the action of IL-1β, Arcalyst reduces the inflammation and symptoms associated with CAPS.
