PG13-MAGE-A3 TCR9W11 Transduced Autologous Peripheral Blood Lymphocytes(National Cancer Institute)

Background:
- MAGE-A3/12 is a type of protein commonly found on certain types of cancer cells, particularly in metastatic cancer. Researchers have developed a process to take lymphocytes (white blood cells) from cancer patients, modify them in the laboratory to target cancer cells that contain MAGE-A3/12, and return them to the patient to help attack and kill the cancer cells. These modified white blood cells are an experimental treatment, but researchers are interested in determining their safety and effectiveness as a possible treatment for cancers that involve MAGE-A3/12.
Objectives:
- To evaluate the safety and effectiveness of anti-MAGE-A3/12 lymphocytes as a treatment for metastatic cancers that have not responded to standard treatment.
Eligibility:
- Individuals at least 18 years of age who have been diagnosed with metastatic melanoma, renal cell cancer, or another type of metastatic cancer that has not responded to standard treatment.
Design:
Participants will be screened with a full medical history and physical examination, as well as blood and urine tests, tumor samples, and imaging studies.
Participants will have leukapheresis to collect enough white blood cells for modification in the laboratory.
Seven days before the start of anti-MAGE-A3/12 treatment, participants will have chemotherapy with cyclophosphamide and fludarabine to suppress the immune system in preparation for the treatment.
After the last dose of chemotherapy, participants will receive the anti-MAGE-A3/12 cells as an infusion for 20 to 30 minutes, followed by a dose of interleukin-2 to keep the anti-MAGE-A3/12 cells alive and active as long as possible. Participants will also receive filgrastim to encourage the production of blood cells.
Participants will remain in the hospital to be monitored for possible side effects, and after release from the hospital will have regular followup exams with blood samples and imaging studies to evaluate the effectiveness of the treatment....
