简要总结
Background:
- Melanoma antigen recognized by T cells (MART-1) is a gene that is present in melanoma cells.
- This study tests an experimental treatment that uses the patient's own lymphocytes (type of white blood cell), which are specially selected and genetically modified with a gene called anti-MART-1 transduced cells (F5) to target and destroy their tumor. Some of the cells are given as an infusion and others are given as a vaccine.
- The anti-MART-1 F5 cells are currently being studied in other patients in combination with chemotherapy and IL-2 (aldesleukin) therapy.
Objectives:
-To determine if the anti-MART-1 F5 treatment can improve the immune system's ability to shrink tumors and to prevent melanoma from recurring.
Eligibility:
- Patients 18 years of age and older whose melanoma has been removed and are currently disease-free, but who are at risk for recurrence.
- Patients who do not have ocular or mucosal melanoma.
- Patients with tissue type human leukocyte antigens (HLA-A)*0201).
Design:
-
Workup: Patients have scans, x-rays, laboratory tests, other tests as needed and leukapheresis, a procedure for collecting white cells to modify in the laboratory and later reinfuse into the patient.
-
Patients are assigned to one of four study groups:
-
Group 1 receives anti-MART-1 F5 cells by 30-minute infusion through a vein on day 0.
-
Group 2 receives anti-MART-1 F5 cells on day 0 followed by injections of MART-1 vaccine, which contains MART-1 and an oil-based liquid called Montanide ISA-51 VG. The vaccine is repeated on day 30.
-
Group 3 receives anti-MART-1 F5 cells on day 0 followed by injections of low-dose IL-2 for 5 days (days 0-4).
-
Group 4 receives anti-MART-1 F5 cells on day 0 followed by MART-1 vaccine and low-dose IL-2 for 5 days. The vaccine is repeated on day 30.
-
Recovery: Patients are monitored closely and given medicines to prevent or treat any side effects of therapy.
-
Leukapheresis: Patients undergo leukapheresis at 1 and 3 months after therapy to collect cells to examine the effects of the treatment on the immune system.
-
Follow-up: Patients return to National Institutes of Health (NIH) 35 days after completing treatment and then at 3 months and every 6 months thereafter for evaluation with a physical examination, review of side effects, laboratory tests and scans. They have blood tests at 3, 6 and 12 months after treatment and then once a year after that. A biopsy may be requested after treatment ends to examine the effects of treatment on the immune system. All patients return to NIH for a physical examination once a year for 5 years and then complete a follow-up questionnaire for another 10 years.
详细描述
Background:
We have engineered human peripheral blood lymphocytes (PBLs) to express an anti-MART-1 T-cell receptor (TCR) that recognizes an HLA-A*0201 restricted epitope derived from the tumor infiltrating lymphocytes (TIL) clone DMF5.
We constructed a single retroviral vector that encodes both alpha and beta chains and can mediate genetic transfer of this T cell receptor (TCR) with high efficiency without the need to perform any selection.
In co-cultures with HLA-A*0201 positive melanoma, anti-MART-1 F5 TCR transduced T cells secreted significant amount of IFN- but no significant secretion was observed in control co-cultures with cell lines.
The anti-MART-1 F5 TCR transduced PBL could efficiently kill HLA-A*0201 positive tumors. There was little or no recognition of normal fibroblasts cells.

结局指标
主要结局
Number of Participants With Adverse Events
时间窗: 4 years
Here is the number of participants with adverse events. For a detailed list of adverse events see the adverse event module.
Percentage of Participants With Immunologic Response
时间窗: 9/24/08-10/9/12
Percentage of participants with an immunologic response of \>20 spots/100,000 cells measured by IFN gamma secretion using enzyme linked immunosorbent spot (ELISPOT) assay. This was done using ELISPOT assay which measures immune response at the single cell level.
