The pursuit of more effective treatments for autoimmune diseases has led to a focus on the interleukin-17 (IL-17) pathway, a key driver of inflammation. While several successful monoclonal antibody-based IL-17 inhibitors are on the market, a new contender, izokibep, is generating significant interest due to its unique molecular characteristics. The assertion that izokibep may achieve higher tissue penetration raises a critical question: Does this translate to greater efficacy?
