Patent abstract

Provided herein are variant human IL-18 (hIL-18) proteins and fusion proteins comprising the variant hIL-18 proteins. Such variant hIL-18 proteins exhibit biological IL-18 activity while having reduced or no detectable binding to inhibitory IL-18BP. Thus, in some embodiments, the variant hIL-18 proteins advantageously retain IL-18 biological activity in the presence of IL-18BP. Such variant hIL-18 and related fusion proteins find use, for example, in the treatment of cancer.
