Overview

IL-15–expressing CAR-T cell therapy is an adoptive cell therapy platform where T cells are genetically engineered to express both a chimeric antigen receptor (CAR) and the cytokine interleukin-15 (IL-15). IL-15 is a critical factor for the survival, proliferation, and metabolic fitness of T cells and natural killer (NK) cells. By co-expressing IL-15, these CAR-T cells aim to overcome the limitations of poor persistence and exhaustion often observed in conventional CAR-T therapies, particularly within the immunosuppressive tumor microenvironment. The specific program developed by Tianjin Cancer Hospital Airport Hospital (as seen in trial ChiCTR2500107167) utilizes this platform to target various hematologic antigens, including CD19, CD20, CD22, BCMA, CD7, and GPRC5D, for the treatment of a wide range of relapsed or refractory B-cell and T-cell malignancies, multiple myeloma, and plasma cell leukemia.
