- Brief Summary
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.
- Detailed Description
Background:
* Adoptive cell therapy (ACT) using autologous tumor infiltrating lymphocytes can mediate the regression of bulky metastatic melanoma when administered along with high-dose aldesleukin (IL-2) following a non-myeloablative lymphodepleting chemotherapy preparative regimen consisting of cyclophosphamide and fludarabine.
* In a series of consecutive trials using this chemotherapy preparative regimen alone or with 2 Gy or 12 Gy total body irradiation (TBI) objective response rates using RECIST criteria were 49%, 52%, and 72%, respectively. Complete regression rates in these three consecutive trials were 12%, 20%, and 40%, respectively strongly suggesting that the addition of TBI could improve the complete regression rate. Of the 20 complete regressions seen in this trial, 19 are on-going at 37 to 82 months.
* Because of the complexity of developing selected TIL for use in adoptive transfer, we have recently developed a simplified method for producing TIL that is more applicable to use in outside institutions. Utilizing young TIL cells (sometimes with CD8 purification) in 105 patients, the objective response rate was 34% with a 6.6 % incidence of complete regressions. All patients in this trial received the cyclophosphamide fludarabine regimen alone.
* Because of the strong suggestion that the addition of TBI to the chemotherapy regimen could increase durable, complete regression rates in patients with metastatic melanoma, we are now attempting to definitively determine whether the addition of TBI to the chemotherapy preparative regimen can improve complete response rates, and overall survival in patients receiving young TIL .
Objectives:
-To determine, in a prospective randomized trial, the complete response rate and survival of patients with metastatic melanoma receiving ACT using young TIL plus aldesleukin treatment following either a chemotherapy preparative regimen alone, or the same chemotherapy preparative regimen plus TBI.
Eligibility:
-Patients who are 18 years or older must have:
* Evaluable metastatic melanoma;
* Metastatic melanoma lesion suitable for surgical resection for the preparation of TIL;
* No contraindications to high-dose aldesleukin administration or total body irradiation;
* No concurrent major medical illnesses or any form of immunodeficiency
Design:
-Patients with metastatic melanoma will have lesions resected and after TIL growth is established patients with will be prospectively randomized to receive ACT with young TIL plus aldesleukin following either a non-myeloablative chemotherapy preparative regimen or this same regimen plus TBI.
