Trial Summary

What is the purpose of this trial?

Background: - An experimental treatment for metastatic melanoma involves cell therapy, in which researchers take white blood cells (lymphocytes) from the tumor tissue, grow them in the laboratory in large numbers, and then use the cells to attack the tumor tissue. Before receiving the cells, chemotherapy is needed to temporarily suppress the immune system to improve the chances that the tumor-fighting cells will be able to survive in the body. In some studies of cell therapy, individuals who have received total body irradiation (TBI) in addition to the chemotherapy (in order to increase the length of time that they do not produce white blood cells) seem to have a slightly better response to the treatment, but it is not known if adding radiation to the cell therapy will cause a better response for all individuals. Researchers are interested in comparing cell therapy given with the usual chemotherapy to cell therapy given with the usual chemotherapy and TBI. Objectives: - To compare the effectiveness of cell therapy given with chemotherapy to cell therapy given with chemotherapy and total body irradiation in individuals with metastatic melanoma. Eligibility: - Individuals at least 18 years of age who have been diagnosed with metastatic melanoma. Design: * Participants will be screened with a physical examination, medical history, blood tests, and tumor imaging studies. * Participants will be divided into two groups: cell therapy with chemotherapy alone (group 1) or cell therapy with chemotherapy plus TBI (group 2). * All participants will provide a tumor sample from either surgery or a tumor biopsy for white blood cell collection. * Participants will have leukapheresis to collect additional white blood cells for cell growth and future testing, and TBI group participants will also provide stem cells to help them recover after radiation. (TBI participants who cannot provide enough stem cells will be moved to the non-radiation treatment group.) * Participants will have chemotherapy with cyclophosphamide (two treatments over 2 days) and fludarabine (five treatments over 5 days) starting 7 days before the cell therapy. Participants in the TBI group will also have TBI for the 3 days immediately before the cell therapy. * All participants will receive the white blood cells, followed by high-dose aldesleukin every 8 hours for up to 5 days after the cell infusion to help keep the therapy cells alive and active. Participants will also have injections of filgrastim to stimulate blood cell production, and participants in the TBI group will also receive their stem cells. * Participants will take an antibiotic for at least 6 months after treatment to prevent pneumonia, and will be asked to return for regular monitoring and followup visits for at least 5 years to evaluate the tumor s response to treatment.

Treatment Details

Interventions

  • Aldesleukin
  • Cyclophosphamide
  • Fludarabine
  • Total Body Irradiation (TBI)
  • Young TIL
  • Young Tumor Infiltrating Lymphocytes
Trial Overview The study is testing if adding total body irradiation (TBI) to chemotherapy before cell therapy improves outcomes in metastatic melanoma patients. Participants are split into two groups: one receives just chemo while the other gets chemo plus TBI before their own grown white blood cells are reintroduced.
