Official Title: A Phase II Study Using Short-Term Cultured Anti-Tumor Autologous Lymphocytes Following a Lymphocyte Depleting Regimen in Metastatic Melanoma

Brief Summary:

Background:

  • Most therapeutic therapies for metastatic melanoma have focused on the ability of T-cell lymphocytes to kill cells of tumors.
  • An adaptive cell transfer therapy has been pioneered, in which cells are grown for a short time in the laboratory. The way they are grown may have a better effect in a patient's body than do other cells that are cultured for a longer time.

Objectives:

  • To determine whether tumor-infiltrating lymphocytes (TIL) can be put in cells removed from patients' tumors or blood and then reinfused, with the purpose of shrinking tumors.
  • To evaluate safety and effectiveness of the treatment.

Eligibility:

  • Patients 18 years of age or older with metastatic cancer melanoma (cancer that has spread beyond the original site).
  • Patient's leukocyte antigen type is human leukocyte antigens (HLA-A) 0201.

Design:

-Patients undergo the following procedures:

  • Leukapheresis (on two occasions). This is a method of collecting large numbers of white blood cells. The cells obtained in the first leukapheresis procedure are grown in the laboratory, and the TIL cells (called young TIL cells) are inserted into the cells using an inactivated (harmless) virus in a process called retroviral transduction. Cells collected in the second leukapheresis procedure are used to evaluate the effe
