Abstract

Introduction In 2022, U.S. Food and Drug Administration (FDA) approved the first biologics, intravenous spesolimab, for acute flare of generalized pustular psoriasis (GPP). The drug works by blocking IL-36 signaling, the key pathway of GPP. Among the known mutations causing GPP, IL36RNmutations are most common, and the presence of IL36RNmutations had been found to affect the clinical manifestations and treatment response of GPP.
