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.
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.
Nearly all patients with non-metastatic Ewing's sarcoma family of tumors (ESFT) and alveolar rhabdomyosarcoma (AR) have a dramatic initial response to multiagent chemotherapy. However, approximately 30 percent of patients develop recurrent disease for which conventional chemotherapy is ineffective and treatment options are limited. Immunotherapy may represent an effective approach for treatment of recurrent ESFT and AR. Experimental evidence has shown that immune mediated anti-tumor effects can occur in vivo when T cells recognize and respond to antigens present on tumor cells. In ESFT and AR, tumor-specific chromosomal translocations resulting in the production of novel fusion proteins have been identified in the great majority of tumors. Peptides derived from these fusion proteins have been shown to function as tumor antigens for cytolytic T cells in animal studies. This protocol will study the safety, feasibility and efficacy of tumor-specific peptide vaccination administered with interleukin-2 therapy with or without autologous T cell infusions in patients with recurrent ESFT and AR.

The production of PEPTIDES or PROTEINS by the constituents of a living organism. The biosynthesis of proteins on RIBOSOMES following an RNA template is termed translation (TRANSLATION, GENETIC). There are other, non-ribosomal peptide biosynthesis (PEPTIDE BIOSYNTHESIS, NUCLEIC ACID-INDEPENDENT) mechanisms carried out by PEPTIDE SYNTHASES and PEPTIDYLTRANSFERASES. Further modifications of peptide chains yield functional peptide and protein molecules.
A 36-amino acid peptide produced by the L cells of the distal small intestine and colon. Peptide YY inhibits gastric and pancreatic secretion.
The middle segment of proinsulin that is between the N-terminal B-chain and the C-terminal A-chain. It is a pancreatic peptide of about 31 residues, depending on the species. Upon proteolytic cleavage of proinsulin, equimolar INSULIN and C-peptide are released. C-peptide immunoassay has been used to assess pancreatic beta cell function in diabetic patients with circulating insulin antibodies or exogenous insulin. Half-life of C-peptide is 30 min, almost 8 times that of insulin.
A 27-amino acid peptide with histidine at the N-terminal and isoleucine amide at the C-terminal. The exact amino acid composition of the peptide is species dependent. The peptide is secreted in the intestine, but is found in the nervous system, many organs, and in the majority of peripheral tissues. It has a wide range of biological actions, affecting the cardiovascular, gastrointestinal, respiratory, and central nervous systems.
A pituitary adenylate cyclase-activating peptide receptor subtype found in LYMPHOCYTES. It binds both PACAP and VASOACTIVE INTESTINAL PEPTIDE and regulates immune responses.
