Anti–Interleukin-17 Monoclonal Antibody Ixekizumab in Chronic Plaque Psoriasis

Abstract
Type 17 helper T cells have been suggested to play a pathological role in psoriasis. They secrete several proinflammatory cytokines, including interleukin-17A (also known as interleukin-17). We evaluated the safety and efficacy of ixekizumab (LY2439821), a humanized anti–interleukin-17 monoclonal antibody, for psoriasis treatment.
