There is one clinical trial.
This is a single arm study. The tumor specimen is analyzed for the presence of a fusion protein which corresponds to available peptides. Patients undergo T cell harvest 10 days after an initial priming peptide-pulsed antigen presenting cell (APC) vaccine is performed. Fresh APCs are utilized for initial priming vaccination. All subsequent vaccinations will use cryopreserved APCs. Minimum number of APCs administered per vaccination is 100,000/kg and maximum is 100,000,000/kg. Patients undergo cytoreductive therapy for the treatment of their particular malignancy. This therapy usually consists of multiagent chemotherapy in the context of a separate protocol. Following chemotherapy, infusion of harvested T cells followed by infusion of peptide-pulsed APC vaccinations occurs every 6 weeks for a total of 3 post-priming vaccinations. Influenza vaccine is administered by intramuscular injection concurrent to peptide-pulsed APC vaccines. Interleukin -2 (IL-2) is administered as a continuous intravenous (IV) infusion for 4 days/week for 3 successive weeks starting on the same day as T cell /peptide-pulsed infusions.

Measure: Number of Participants With an Immune Response to Tumor-specific and Non-tumor Specific Peptides During a Period of Immune Reconstitution Time: 20 weeks post vaccinationDescription: CD4 counts were measured from peripheral blood using standard flow cytometric techniques at the following timepoints: 2 months post-chemotherapy, 4 months post-chemotherapy and 6 months post-chemotherapy. To be eligible for evaluation for this endpoint, patient much have been <10 years of age and sustained a CD4 count of <300 cells/mcl upon completion of standard therapy. Recovery was defined as a CD4 count > 500 cells/mcl at any timepoint within 6 months of completing chemotherapy.
Measure: The Percent of Patients Who Recover CD4 Counts Within 6 Months of Completion of Chemotherapy Time: 2 to 6 monthsDescription: Immune responses were measured following 3 sequential influenza vaccines during the same period as the peptide-pulsed dendritic cell vaccines.
Measure: Number of Participants With an Immune Response to the Translocation Breakpoint Peptide Time: 5 yearsDescription: Immune response was defined as a percent specific lysis of >10% following challenge with peptide pulsed targets, or interferon gamma production following challenge with peptide pulsed targets >2-fold that found with no-peptide controls or a proliferation index >3.0.
Measure: Number of Participants With an Immune Response to Non-Tumor-specific Peptide E7 Time: 5 yearsDescription: Immune response was defined as a percent specific lysis of >10% following challenge with tumor peptide pulsed targets, or interferon gamma production following challenge with tumor peptide pulsed targets >2-fold that found with no-peptide controls or a proliferation index >3.0 to tumor peptide targets.Tumor specific peptides: Ewings sarcoma Type 1: EF-1 (EWS/FLI-1)*SSSYGQQN/PSYDSVRRGA,Ewing's Sarcoma Type 2: EF-2 (EWS/FLI-2)* SSSYGQ/QSSLLAYNT, Alveolar rhabdomyosarcoma: PXFK (PAX3/FKHR)† TIGNGLSPQ/NSIRHNLSL.

Measure: Number of Participants With an Immune Response to Tumor-Specific Peptides at the Time of Presentation Time: Once per enrollmentDescription: Overall survival is defined as the time between the first day of treatment to the day of death.
Measure: Percentage of Participants Overall Survival Time: 5 yearsDescription: Event free survival is calculated from the date of diagnosis for patients enrolled with newly diagnosed metastatic disease and from the date of the last recurrence detection before enrollment on this study for patients with recurrent disease.
Measure: Percent of Participants: Event Free Survival Time: 5 yearsDescription: Here are the number of participants with adverse events. For the detailed list of adverse events see the adverse event module.
Measure: Number of Participants With Adverse Events Time: 5 yearsDescription: Overall survival is defined as the time between the first day of treatment to the day of death.
Measure: Median Overall Survival Time: 5.4 years
