Anti-VEGFR2 CD8 cell therapy(National Cancer Institute)

Background:
The National Cancer Institute (NCI) Surgery Branch has developed an experimental therapy for treating patients metastatic cancer that involves taking white blood cells from the patient, growing them in the laboratory in large numbers, genetically modifying these specific cells with a type of virus (retrovirus) to attack only the tumor cells, and then giving the cells back to the patient. This type of therapy is called gene transfer. In this protocol, we are modifying the patient s white blood cells with a retrovirus that has the gene for anti-vascular endothelial growth factor receptor (VEGFR2) incorporated in the retrovirus.
Objectives:
- To determine a safe number of these cells to infuse and to see the safety and effectiveness of cell therapy using anti-VEGFR2 gene modified tumor white blood cells to treat recurrent or relapsed cancer.
Eligibility:
- Individuals greater than or equal to 18 years of age and less than or equal to 70 years of age who have been diagnosed with metastatic cancer that has not responded to or has relapsed after standard treatment.
Design:
Work up stage: Patients will be seen as an outpatient at the National Institutes of Health (NIH) clinical Center and undergo a history and physical examination, scans, x-rays, lab tests, and other tests as needed
Leukapheresis: If the patients meet all of the requirements for the study they will undergo leukapheresis to obtain white blood cells to make the anti-VEGFR2 cells. {Leukapheresis is a common procedure which removes only the white blood cells from the patient.}
Treatment: Once their cells have grown the patients will be admitted to the hospital for the conditioning chemotherapy, the anti-VEGFR2 cells and aldesleukin. They will stay in the hospital for about4 weeks for the treatment.
Follow up: Patients will return to the clinic for a physical exam, review of side effects, lab tests, and scans about every 1-3 months for the first year, and then every 6 months to 1 year as long as their tumors are shrinking. Follow up visits will take up to 2 days.
