Clinical trial: Anti-MART-1 F5 Cells Plus ALVAC MART-1 Vaccine to Treat Advanced Melanoma

Summary: Background:
  -  Melanoma antigen recognized by T-cells (MART)-1 is a protein present in melanoma cells.
  -  An experimental procedure developed for treating patients with melanoma uses the anti-MART-1 F5 gene and a type of virus to make special cells called anti-MART-1 F5 cells that are designed to destroy the patient's tumor. These cells are created in the laboratory using the patient's own tumor cells or blood cells.
  -  The treatment procedure also uses a vaccine called plaque purified canarypox vector (ALVAC) MART-1, made from a virus that ordinarily infects canaries and is modified to carry a copy of the MART-1 gene. The virus cannot reproduce in mammals, so it cannot cause disease in humans. When the vaccine is injected into a patient, it stimulates cells in the immune system that may increase the efficiency of the anti-MART-1 F5 cells.
  Objectives:
  -To evaluate the safety and effectiveness of anti-MART-1 F5 and the ALVAC vaccine in treating patients with advanced melanoma.
  Eligibility:
  -Patients 18 years of age with metastatic melanoma for whom standard treatments have not been effective.
  Design:
  -  Patients undergo scans, x-rays and other tests and leukapheresis to obtain white cells for laboratory treatment.
  -  Patients have 7 days of chemotherapy to prepare the immune system for receiving the anti-MART-1 F5.
  -  Patients receive the ALVAC vaccine, anti-MART-1 F5 cells and interleukin-2 (IL-2) (an approved treatment for advanced melanoma). The anti-MART-1 F5 cells are given as an infusion through a vein. The vaccine is given as injections just before the infusion of anti-MART-1 F5 cells and again 2 weeks later. IL-2 is given as a 15-minute infusion every 8 hours for up to 5 days after the cell infusion for a maximum of 15 doses.
  -  After hospital discharge, patients return to the clinic for periodic follow-up with a physical examination, review of treatment side effects, laboratory tests and scans every 1 to 6 months.

Detailed description: Background:
  -  We have engineered human PBLs to express an anti-MART-1 T-cell receptor that recognizes an human leukocyte antigens (HLA-A) 0201 restricted epitope derived from the tumor infiltrating lymphocytes (TIL) clone DMF5.
  -  We constructed a single retroviral vector that contains both alpha and infinity 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 interferon (IFN)-(but no significant secretion was observed in control co-cultures with cell lines.
  -  The anti-MART-1 F5 TCR transduced peripheral blood lymphocytes (PBL) could efficiently kill HLA-A 0201 positive tumors. There was little or no recognition of normal fibroblasts cells.
  -  This TCR is over 10 times more reactive with melanoma cells than the MART-1 TCR that mediated tumor regression in two patients with metastatic melanoma.
  -  In this trial we would like to test our hypothesis that the addition of an anti-tumor ALVAC vaccine will result in clinical tumor regression and persistence of the transferred cells (as is the case in murine models).
  Objectives:
  Primary objectives:
  -Determine if the administration of anti-MART-1 F5 TCR -engineered peripheral blood lymphocytes, ALVAC anti-tumor immunization, and aldesleukin to patients following a nonmyeloablative but lymphoid depleting preparative regimen will result in clinical tumor regression in patients with metastatic melanoma.
  Secondary objectives:
  -  Determine the in vivo survival of TCR gene-engineered cells.
  -  Determine the toxicity profile of this treatment regimen.
  Eligibility:
  Patients who are HLA-A 0201 positive and 18 years of age or older must have:
  -  metastatic melanoma;
  -  previously received and have been a non-responder to or recurred after aldesleukin;
  -  normal values for basic laboratory values.
  Patients may not have:
  -  concurrent major medical illnesses;
  -  any form of primary or secondary immunodeficiency;
  -  severe hypersensitivity to any of the agents used in this study;
  -  contraindications for high dose aldesleukin administration.
  -  Design:
  -  peripheral blood mononuclear cells (PBMC) obtained by leukapheresis (approximately 5 times 10^9 cells) will be cultured in the presence of anti-CD3 (OKT3) and aldesleukin in order to stimulate T-cell growth.
  -  Transduction is initiated by exposure of approximately 10^8 to 5 X 10^8 cells to retroviral vector supernatant containing the anti-MART-1 F5 TCR genes. These transduced cells will be expanded and tested for their anti-tumor activity.
  -  Once engineered PBMC are demonstrated to be biologically active according to the strict-criteria outlined in the Certificate of Analysis, patients will receive a nonmyeloablative but lymphocyte depleting preparative regimen consisting of cyclophosphamide and fludarabine followed by intravenous infusion of ex vivo tumor reactive, TCR gene-transduced PBMC plus intravenous (IV) aldesleukin (720,000 IU/kg q8h for a maximum of 15 doses). Approximately 2 hours prior to cell infusion, patients will be immunized with ALVAC virus expressing the tumor antigen. ALVAC immunization will be repeated at 2 weeks.
  -  Patients will undergo complete evaluation of tumor with physical examination, computed tomography (CT) of the chest, abdomen and pelvis and clinical laboratory evaluation four to six weeks after treatment and then monthly for approximately 3 to 4 months or until off study criteria are met.
  -  The study will be conducted using a phase II optimal design where initially 21 evaluable patients will be enrolled. If 0 or 1 of the 21 patients experiences a clinical response, then no further patients will be enrolled but if 2 or more of the first 21 evaluable patients enrolled have a clinical response, then accrual will continue until a total of 41 evaluable patients have been enrolled.
  -  The objective will be to determine if the combination of high dose aldesleukin, lymphocyte depleting chemotherapy, ALVAC immunization and anti-MART-1 F5 TCR-gene engineered lymphocytes is able to be associated with a clinical response rate that can rule out 5 percent (p0=0.05) in favor of a modest 20 percent partial response (PR) plus complete response (CR) rate (p1=0.20).
