Testing CAR-T Cell Therapy in Recurrent Epithelial Ovarian Cancer
This phase I trial is to test the safety of using a new treatment called autologous T lymphocyte chimeric antigen receptor cells against the B7-H3 antigen (CAR.B7-H3 T cells) in patients with ovarian cancer that has come back (recurrent). CAR.B7-H3 T cells combine two different ways the body fights cancer, antibodies and T cells. Antibodies are proteins that protect the body from foreign invaders like bacteria. Antibodies work by attaching to these bacteria or substances, which stops them from growing and causing bad effects. T cells, also called T lymphocytes, are special infection fighting blood cells that can kill viruses and other cells, including tumor cells. Antibodies and T cells have been used to treat patients with cancer. They both have shown promise, but neither alone has been able to cure most patients. This study will combine both T cells and antibodies to create a more effective treatment.

PRIMARY OBJECTIVE:
I. To determine the safety and tolerability of anti-B7-H3 CAR T-cells (autologous CAR.B7-H3 T cell product) administered intraperitoneally after lymphodepletion with cyclophosphamide and fludarabine to subjects with relapsed or refractory platinum-resistant epithelial ovarian cancer.
SECONDARY OBJECTIVES:
I. To determine the disease control rate (DCR) mediated by autologous CAR.B7-H3 T cell product administered to subjects with relapsed or refractory platinum-resistant epithelial ovarian cancer.
II. To determine the progression free survival (PFS) after lymphodepletion with cyclophosphamide and fludarabine and administration of the CAR.B7-H3 T cell product in subjects with relapsed or refractory platinum-resistant epithelial ovarian cancer.
III. To determine the overall survival (OS) in adult subjects with relapsed or refractory platinum-resistant epithelial ovarian cancer following lymphodepletion with cyclophosphamide and fludarabine and infusion with autologous CAR.B7-H3 T cells.
EXPLORATORY OBJECTIVES:
I. To measure if CAR.B7-H3 T cells administered intraperitoneally enter the blood stream and persist.
II. To measure and compare cytokines and immunophenotypes in the peripheral blood after CAR.B7-H3 T cell administration.
III. To evaluate changes in the tumor microenvironment before and after treatment with CAR.B7-H3 T cells.
IV. To measure changes in B7.H3 expression before and after treatment with CAR.B7-H3 T cells.
V. To study immunogenomics and evaluate changes in the expression of genes and/or proteins that may be relevant to toxicity and durability of response to therapy in the ascites fluid before and after treatment.
OUTLINE: This is a dose-escalation study of CAR.B7-H3 T cells.
LYMPHODEPLETION: Patients receive cyclophosphamide intravenously (IV) and fludarabine phosphate IV for 3 days per institutional standard.
CAR.B7-H3 T CELL ADMINISTRATION: 2-14 days after completion of lymphodepletion, patients receive CAR.B7-H3 T cells intraperitoneally over 5-10 minutes weekly for 3 weeks. Patients undergo magnetic resonance imaging (MRI) and computed tomography (CT).
After completion of study treatment, patients are followed up for 3 weeks, then every 3 months for 2 years, and then every 6 months for 5 years.
