Filter by:Arm A: Peripheral blood apheresis by harvesting chemotherapy-naive T cells and populations enriched for professional APCs. T cells and APCs are separated from the apheresis product using countercurrent centrifugal elutriation and a monocyte rich fraction is collected. Autologous T cell transplantation during immunotherapy. Arm B: Cell harvesting is performed as soon as possible. Both Arm A and B: Patients receive intravenous infusion of irradiated peptide-pulsed antigen presenting cell vaccination (APC) products as well as intramuscular injection of influenza vaccine on the same day. Recombinant human IL-2 is administered within 4 hours of the peptide pulsed vaccine by continuous intravenous infusion for 4 days per week for 3 successive weeks. Primary toxic effect of this therapy is expected to be related to the IL-2 therapy. Patients with Grade 2 neurologic or cardiac or any Grade 3 or 4 toxic effects will discontinued IL-2 therapy. If toxic effect is not resolved in 72-hours, the patient may remain on study but will not receive any further IL-2.
The prognosis for patients with metastatic Ewing's sarcoma family of tumors (ESF), rhabdomyosarcoma (RMS), and neuroblastoma (NBL) remains dismal, with less than 25% long-term disease-free survival. Though less grave, the prognosis for cure for other high-risk patients is approximately 50%. New treatment strategies, including the identification of highly active new agents, maximizing the dose intensity of the most active standard drugs, and the development of improved methods of consolidation to eradicate microscopic residual disease, are clearly needed to improve the outcome of these patients. This protocol will address these issues by commencing with a Phase II window, for the highest risk patients, to evaluate a series of promising drugs with novel mechanisms of action. All patients will then receive 5 cycles of dose-intensive "best standard therapy" with doxorubicin (adriamycin), vincristine, and cyclophosphamide (VAdriaC). Patients at high risk of relapse will continue onto a phase I consolidation regimen consisting of three cycles of dose-escalated Melphalan, Ifosfamide, Mesna, and Etoposide (MIME). Peripheral blood stem cell transfusions (PBSCT) and recombinant human G-CSF will be used as supportive care measures to allow maximal dose-escalation of this combination regimen.
