B7-H3-Specific Chimeric Antigen Receptor Autologous T-Cell Therapy for Pediatric Patients With Solid Tumors (3CAR)
3CAR is being done to investigate an immunotherapy for patients with solid tumors. It is a Phase I clinical trial evaluating the use of autologous T cells genetically engineered to express B7-H3-CARs for patients ≤ 21 years old, with relapsed/refractory B7-H3+ solid tumors. This study will evaluate the safety and maximum tolerated dose of B7-H3-CAR T cells.The purpose of this study is to find the maximum (highest) dose of B7-H3-CAR T cells that are safe to give to patients with B7-H3-positive solid tumors.
Primary objective
To determine the safety of one intravenous infusion of autologous, B7-H3-CAR T cells in patients (≤ 21 years) with recurrent/refractory B7-H3+ solid tumors after lymphodepleting chemotherapy
Secondary objective
To evaluate the antitumor activity of B7-H3-CAR T cells
Exploratory objectives
- To evaluate the tumor environment after treatment with B7-H3-CAR T cells
- To assess the immunophenotype, clonal structure and endogenous repertoire of B7-H3-CAR T cells and unmodified T cells
- To characterize the cytokine profile in the peripheral blood after treatment with B7-H3-CAR T cells

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: Treatment Phase
During the treatment phase, the participant receives an infusion of the B7-H3-CAR T cells that were made in the Collection and Manufacturing Phase.
Chemotherapy is given for several days prior to the cellular infusion.
Patients are then monitored for possible side effects, as well as effects of the treatment on their cancer.

Fludarabine phosphate is a synthetic purine nucleoside analog.
It acts by inhibiting DNA polymerase, ribonucleotide reductase and DNA primase by competing with the physiologic substrate, deoxyadenosine triphosphate, resulting in inhibition of DNA synthesis.
Intravenous
Other Names:
Cyclophosphamide is a nitrogen mustard derivative.
It acts as an alkylating agent that causes cross-linking of DNA strands by binding with nucleic acids and other intracellular structures, thus interfering with the normal function of DNA.
Intravenous
Other Names:
Mesna is a synthetic sulfhydryl (thiol) compound.
Mesna contains free sulfhydryl groups that interact chemically with urotoxic metabolites of oxaza-phosphorine derivatives such as cyclophosphamide and ifosfamide
Other Names:
The study participant will receive B7-H3-CAR T cells by vein, through either an IV or a central line.
