Genetically Engineered Lymphocytes in Treating Patients with Metastatic Cancer or Cancer That Cannot Be Removed by Surgery Receiving Chemotherapy and Aldesleukin
Basic Trial Information
This phase I/II trial studies the side effects and best dose of genetically engineered lymphocytes and to see how well it works in treating patients with cancer that has spread to other parts of the body or cancer that cannot be removed by surgery receiving chemotherapy and aldesleukin. Placing a gene that has been created in the laboratory into white blood cells may make the body build an immune response to kill cancer cells.
Further Study Information
I. To evaluate the safety of the administration of anti-mesothelin chimeric antigen receptor (CAR) engineered peripheral blood lymphocytes in patients receiving the non- myeloablative conditioning regimen, and aldesleukin.
II. Determine if the administration of anti-mesothelin CAR engineered peripheral blood lymphocytes and aldesleukin to patients following a nonmyeloablative but lymphoid depleting preparative regimen will result in clinical tumor regression in patients with metastatic or unresectable cancer that expresses mesothelin.
I. Determine the in vivo survival of CAR gene-engineered cells.
OUTLINE: This is a phase I, dose-escalation study of mesothelin-specific chimeric antigen receptor-engineered peripheral blood lymphocytes followed by a phase II study.
PREPARATIVE REGIMEN: Patients receive cyclophosphamide intravenously (IV) over 1 hour on days -7 and -6 and fludarabine phosphate IV over 30 minutes on days -5 to -1.
CELL INFUSION AND ALDESLEUKIN ADMINISTRATION: Patients receive mesothelin-specific chimeric antigen receptor-engineered peripheral blood lymphocytes IV over 20-30 minutes on day 0 and aldesleukin IV over 15 minutes every 8 hours for up to 15 doses.
After completion of study treatment, patients are followed up at 4-6 weeks, annually for 5 years, and then periodically for 10 years.
Metastatic or unresectable measurable cancers that express mesothelin; as in other protocols conducted by Dr. Hassan in the National Cancer Institute (NCI), epithelial mesotheliomas and pancreatic cancers do not need to be assessed for mesothelin expression since all of these tumors have been shown to express mesothelin; other metastatic or unresectable cancers must be shown to expresses mesothelin as assessed by reverse transcriptase-polymerase chain reaction (RT-PCR) or immunohistochemistry on tumor tissue; bi-phasic mesotheliomas must express mesothelin on greater than 50% of the cells in the epithelial component; diagnosis will be confirmed by the Laboratory of Pathology, NCI
Patients must have previously received at least one systemic standard care (or effective salvage chemotherapy regimens) for metastatic or unresectable disease, if known to be effective for that disease, and have been either non-responders (progressive disease) or have recurred
