5. Study Description

Brief Summary
This phase I trial tests the safety, side effects, and best dose of TAG72-chimeric antigen receptor (CAR) T cells in treating patients with epithelial ovarian cancer that remains despite treatment with platinum therapy (platinum resistant). T cells are infection fighting blood cells that can kill tumor cells. The T cells given in this study will come from the patient and will have a new gene put in them that makes them able to recognize TAG72, a protein on the surface of tumor cells. These TAG72-specific T cells may help the body's immune system identify and kill TAG72+ cancer cells.
Detailed Description
PRIMARY OBJECTIVES: I. To evaluate the safety and tolerability of TAG72-CAR T cells in participants with recurrent epithelial ovarian cancer (EOC). II To determine the maximum tolerated dose (MTD). III. To identify the recommended phase 2 dose (RP2D). SECONDARY OBJECTIVES: I. Persistence of CAR T cells in blood and peritoneal cavity pre- and 28 days post-infusion. II. Response based on Immune-Related Response Criteria (irRC). III. Estimate the 6 month progression free survival rate. IV. Estimate median overall survival. V. TAG72 expression on tumor cells by immunohistochemistry (IHC) and/or flow cytometry; VI. Describe the serum cytokine profile pre- and post-CAR T cell infusion to assess potential cytokine release syndrome (CRS) toxicity and CAR T cell effector function. EXPLORATORY OBJECTIVES: I. Phenotypes and frequencies of immune cell subsets in the peripheral blood pre- and post- therapy: analysis will include CD4:CD8 ratios, differentiation status (CD62L, CD27, CD45 RA/RO), and exhaustion markers (PD1, Tim3, LAG3), trafficking (CCR7, alpha4beta7), proliferation markers (ki67) and effector functions (cytotoxicity, Th1/Th2 cytokines, and CD107a degranulation) on endogenous and CAR+ T cells. II. Phenotype of tumor-infiltrating lymphocytes (TILs). III. Gene expression (by RNA-seq) of circulating tumor cells (CTCs). IV. Circulating cell-free deoxyribonucleic acid (cfDNA) in peripheral blood by whole exome sequencing. V. CAR immunogenicity based on the presence of anti-TAG72 CAR antibodies or T cell mediated immune responses. OUTLINE: This is a dose-escalation study of TAG72-CAR T cells. Patients receive fludarabine intravenously (IV) and cyclophosphamide IV on days -5 to -3. Patients receive TAG72-CAR T cells IP on day 0. After completion of study treatment, patients are followed up at 1, 7, 14, 21, 28, 60 and 90 days, 6, 9, and 12 months, then for up to 15 years.
