Interventions and Outcome Measures

Arms

experimental: iC9-CAR.B7-H3 T cells

Specimen will be collected to prepare the iC9-CAR.B7-H3 T cells. Disease-fighting T cells will be isolated and modified to prepare the iC9-CAR.B7-H3 T cells. In part 2, the iC9-CAR.B7-H3 T cells are given by infusion after completion of lymphodepletion chemotherapy.

Interventions

iC9-CAR.B7-H3 T Cell Therapy

iC9-CAR.B7-H3 T cells will then be administered intravenously

cyclophosphamide

cyclophosphamide 300 mg/m2 IV will be given.

fludarabine

fludarabine 30 mg/m2 IV will be given.

Primary outcome measure

  • Toxicity: NCI-CTCAE [ Time Frame: Up to 4 weeks ]
  • Toxicity: Cytokine Release Syndrome (CRS) [ Time Frame: Up to 8 weeks after infusion of Biological/Vaccine ]
  • Toxicity: Immune effector cell-associated neurotoxicity syndrome (ICANS) [ Time Frame: Up to 4 weeks ]
