This phase II trial will examine whether genetically reprogramming a patient's disease fighting white blood cells may build an immune response to kill cancer cells that express the NY-ESO-1 protein. In this study, this genetic therapy will be given during a stem cell transplant along with a vaccine therapy. The vaccine will be made using the NY-ESO-1 protein and may help to stimulate the engineered immune response to tumor cells.
PRIMARY OBJECTIVES:
I. To evaluate whether we can safely administer NY-ESO-1 T cell receptor transduced autologous peripheral blood mononuclear cells (PBMCs) (up to 1x10\^9 cells) along with an NY-ESO-1 dendritic cell vaccine and low dose IL-2 to patients with advanced malignancies.
II. To evaluate the feasibility of delivering two patient-specific cell therapies, the NY-ESO-1 TCR transgenic peripheral blood mononuclear cell (PBMC) and NY-ESO-1 (157-165) peptide pulsed dendritic cells (DC), within a technically challenging study design that requires other significant interventions, like a lymphodepleting conditioning regimen and post-infusion of subcutaneous low dose interleukin (IL)-2 (aldesleukin).
III. To determine the rate of objective tumor responses, by Response Evaluation Criteria in Solid Tumors (RECIST) objective response criteria.
SECONDARY OBJECTIVES:
I. To determine the persistence of NY-ESO-1 TCR-engineered cells. This will be determined by temporally analyzing peripheral blood samples for the presence of T cells with the transduced NY-ESO-1 TCR by tetramer or dextramer analysis.
II. To explore the homing and persistence of the adoptively transferred NY-ESO-1 TCR-engineered PBMC in secondary lymphoid organs and tumor deposits via positron emission tomography (PET)-based imaging using the PET tracer fluorodeoxyglucose ([18F]FDG).
OUTLINE:
CONDITIONING: Patients receive cyclophosphamide intravenously (IV) over 1 hour on days -5 to -4 and fludarabine phosphate IV over 30 minutes on days -4 to -1.
TRANSPLANT: Patients receive NY-ESO-1 TCR transduced autologous PBMC IV on day 0. Patients also receive NY-ESO-1 (157-165) peptide pulsed dendritic cell vaccine therapy intradermally (ID) on days 1, 14, and 30 and aldesleukin subcutaneously (SC) twice daily (BID) on days 1-14. Patients may receive 3 additional doses of NY-ESO-1 (157-165) peptide pulsed dendritic cell vaccine therapy after day 90.
After completion of study treatment, patients are followed up at 30, 45, 60, and 75 days; every 3 months for 2 years; every 6 months for 3 years; and annually thereafter.

CONDITIONING: Patients receive cyclophosphamide IV over 1 hour on days -5 to -4 and fludarabine phosphate IV over 30 minutes on days -4 to -1. TRANSPLANT: Patients receive NY-ESO-1 reactive TCR retroviral vector transduced autologous PBL IV on day 0. Patients also receive NY-ESO-1 (157-165) peptide pulsed dendritic cell vaccine therapy ID on days 1, 14, and 30 and aldesleukin SC BID on days 1-14. Patients may receive 3 additional doses of NY-ESO-1 (157-165) peptide pulsed dendritic cell vaccine therapy after day 90.
