Importantly, STK-009 induced the expression of cytotoxic machinery, pro-survival, and proliferative genes in tumor-infiltrating SYNCAR-002 (figure 3). Conclusions These findings validate that the orthogonal IL-2 platform has the potential to improve the efficacy and durability of CAR T therapy for solid tumor targets such as GPC3 by selectively expanding CAR-T cells in vivo and activating CAR-T cells in a hostile tumor microenvironment.
Secondary endpoints include assessments of response, pharmacokinetics, and immunogenicity. Exploratory endpoints include assessment of immune cell populations, and relevant gene/protein expression, as well as persistence, phenotype, and functionality of SYNCAR-001 in the peripheral blood and/or bone marrow in response to STK-009.
