|ClinicalTrials.gov Identifier: NCT01212887|

RATIONALE: Placing a gene into T cells may improve the body's ability to recognize cancer cells and build an immune response to fight cancer. Drugs used in chemotherapy, such as cyclophosphamide and fludarabine phosphate, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Biological therapies, such as aldesleukin, may stimulate the immune system in different ways and stop cancer cells from growing. Giving specially treated T cells together with cyclophosphamide, fludarabine phosphate, and aldesleukin may kill more tumor cells.
PURPOSE: This phase I clinical trial is studying the side effects and best dose of treated T cells when given together with cyclophosphamide, fludarabine phosphate, and aldesleukin in treating patients with cancer.

- To evaluate the feasibility of MFE23 scFv-expressing autologous anti-CEA MFEz T lymphocytes in combination with preconditioning chemotherapy comprising cyclophosphamide and fludarabine phosphate plus aldesleukin in patients with CEA-positive tumors.
- To assess the toxicity of this regimen in these patients.
- To determine the dose of MFE23 scFv-expressing autologous anti-CEA MFEz T lymphocytes required to give optimal survival of these cells in the circulation (recommended phase II dose).
- To assess whether MFE23 scFv-expressing autologous anti-CEA MFEz T lymphocytes isolated from the circulation are functional.
- To determine the preliminary tumor response to MFE23 scFv-expressing autologous anti-CEA MFEz T lymphocytes.
- To evaluate the safety of MFE23 scFv-expressing autologous anti-CEA MFEz T lymphocytes.
OUTLINE: This is a phase I, dose-escalation study of MFE23 scFv-expressing autologous anti-CEA MFEz T lymphocytes.
Patients undergo leukapheresis 7-14 days before study therapy begins. Cells are then transduced with a retrovirus vector and expanded to produce MFE23 scFv-expressing autologous anti-CEA MFEz T lymphocytes.
Patients receive preconditioning chemotherapy comprising fludarabine phosphate IV over 15 minutes on days -5 to -1 or cyclophosphamide IV over 1 hour on days -7 to -6 and fludarabine phosphate IV over 15 minutes on days -5 to -1. They receive MFE23 scFv-expressing autologous anti-CEA MFEz T lymphocytes IV over 30 minutes on day 0. Patients also receive high-dose aldesleukin IV over 15 minutes every 8 hours for up to 12 doses beginning on day 0, in the absence of disease progression or unacceptable toxicity. If there is evidence of MFE23 scFv-expressing autologous anti-CEA MFEz T lymphocytes survival, patients may receive additional high-dose aldesleukin.
Patients undergo blood sample collection periodically for pharmacokinetic and pharmacodynamic studies. Some patients may undergo a tumor biopsy.
After completion of study treatment, patients are followed up every 2 weeks for 6 weeks, every 4 weeks for 6 months, every 3 months for 1 year, and then every 6 months thereafter.
