Melanoma | Biological: tvs-CTL Vaccine | Phase 1 |
The rate of progression free survival at one (1) year is < 20% for patients with stage IV metastatic melanoma, despite aggressive cytotoxic chemotherapy regimens and newly approved immunomodulatory and targeted therapy. Immunotherapy seems to hold the most promise for achieving prolonged survival or even cure, therefore,efforts have focused on several different approaches. Such approaches have used tumor vaccination, adoptive transfer of tumor infiltrating lymphocytes, and even monoclonal antibodies, unconjugated or conjugated to cytokines, toxins, or radionucleotides.
The tumor-associated antigen GD2 has been noted on the surface of several tumors, most notably neuroblastoma, but is expressed on melanoma as well. Clinical studies have shown activity of a GD2-specific chimeric T-cell receptor expressed on activated, autologous, T-cells in patients with neuroblastoma. It is the investigators intention to enrich peripheral blood mononuclear cells (PBMC) of patients with stage IV metastatic melanoma with vaccine-specific T-cells through pre-harvest/ phlebotomy vaccination with common, well understood vaccines. The investigators will then modify the T-cells to attack the GD2 antigen. These tumor redirected, vaccine specific, activated T-cells will then be infused into the patient following revaccination with the common vaccines. The Investigators will monitor expansion of the modified T-cells through serial polymerase chain reaction (PCR) assays following vaccination.
The Investigators then intend to re-vaccinate with the selected vaccines one month following infusion and monitor for expansion of the modified T-cells.

- Measurement of infusion related adverse events to evaluate the safety of infused T-cells [ Time Frame: 4 weeks ]To evaluate the safety of autologous, receptor-transduced, activated T-cells, enriched for vaccine-specific cytotoxic T-lymphocytes (tvs-CTL)
- PCR measurement of retroviral construct to measure persistence of infused T-cells [ Time Frame: 4 weeks ]To evaluate how long the infused T-cells remain in the blood stream
- Measurement of replication competent retrovirus to evaluate the safety of infused T-cells [ Time Frame: 4 weeks ]To evaluate the safety of autologous, receptor-transduced, activated T-cells, enriched for vaccine-specific cytotoxic T-lymphocytes (tvs-CTL)
- PCR measurement of retroviral construct to measure the expansion of infused T-cells [ Time Frame: 12 months ]To determine the expansion of infused tvs-CTL in response to repeat vaccination with previously administered vaccines
- PCR measurement of retroviral construct to compare frequency of peripheral tvs-CTL population pre-infusion vs post-revaccination [ Time Frame: 12 months ]To compare the frequency of tvs-CTL in the peripheral blood, after revaccination, to the frequency noted in the prior study of autologous activated, CAR-transduced T-cells infused in patients with relapsed, refractory Stage IV melanoma
- Imaging studies to measure tumor response [ Time Frame: 10 weeks ]Evaluate tumor response to infusion of tvs-CTL and repeat vaccination post-infusion.
