Immunotherapy for Solid Tumor Malignancies in Pediatrics Using Interleukin-15 and -21 Armored Glypican-3-specific Chimeric Antigen Receptor T Cells

Is NCT07148050 recruiting? Yes, currently enrolling (Jun 2026). This Phase 1 trial studies SC-CAR.GPC3xIL15.21 CAR T cells for solid tumor (excluding cns).

Phase 1RecruitingSeattle Children's HospitalNCT07148050Data as of Jun 2026

Treatment: SC-CAR.GPC3xIL15.21 CAR T cellsThis Phase 1, open-label, non-randomized study will enroll pediatric and young 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). A child or young adult 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.
