This Phase 1, open-label, non-randomized study will enroll adult subjects with relapsed or refractory non-central nervous system (CNS) malignant solid tumors expressing glypican-3 (GPC3) to examine the safety, feasibility, and efficacy of administering T cell products derived from peripheral blood mononuclear cells (PBMC) that have been genetically modified to co-express a GPC3-specific chimeric antigen receptor (CAR), interleukin (IL)-15 and IL-21 as well as the inducible caspase 9 (iC9) suicide gene (SC-CAR.GPC3xIL15.21 T cells).
An adult participant meeting all eligibility criteria and meeting none of the exclusion criteria will have a blood sample collected, which will be used to bioengineer the CAR T cells targeting their tumor.
