A Pilot Study of Tumor-Specific Peptide Vaccination and IL-2 With or Without Autologous T Cell Transplantation in Recurrent Pediatric Sarcomas

• Status: Completed
• Trial end date: 2007-10-25

Summary

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.
