Provided are methods, and reagents and kits for performing such methods, directed to treating subjects with
cancer, including subjects with hematological cancers and subjects with
solid tumors, including subjects with relapsed and / or
refractory hematological cancers, subjects with metastatic, recurrent, relapsed, unresectable, and / or advanced tumors. Provided are methods of treating
cancer comprising administering a
decoy-resistant
interleukin 18 (DR-18), including e.g., using combination therapies comprising administering a DR-18 and a multi-specific therapeutic. Methods may also include selecting a patient, and administering a DR-18 to result in enhanced cytotoxic activity of immune cells in the patient to treat the subject for
cancer. Also provided are methods for administration of DR-18, to prime immune cells present in the subject, and administration of one or more agents that activate the primed immune cells, resulting in enhanced cytotoxic activity, thereby treating the cancer.
