Interleukin 1 receptor accessory protein (IL1RAP) is a receptor that activates signaling pathways triggered by IL1α/β, IL33 and IL36α/β/γ, which are involved in several autoimmune or inflammatory disorders, including psoriasis, gout or systemic sclerosis. Innovent Biologics Co. Ltd. presented data for their anti-IL1RAP antibody IBI-3011, a fully humanized IgG1 antibody targeting IL1RAP that blocks those pathways.
