Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 5 to 35 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Patients with fusion protein bearing, metastatic malignancies of the following histologic subtypes are eligible for evaluation for treatment on this protocol: alveolar rhabdomyosarcoma (AR), and Ewing's sarcoma family of tumors (ESFT) which includes classical, atypical and extraosseous Ewing's sarcoma, peripheral primitive neuroectodermal tumors, peripheral neuroepithelioma, primitive sarcoma of bone, and ectomesenchymoma. Eligibility will not be confirmed until the presence of a tumor-specific fusion protein is documented by reverse transcription polymerase chain reaction (RT-PCR) which corresponds to one of the tumor-specific peptides available for vaccination.
  • Patients with Stage IV or metastatic disease are eligible to be enrolled on study at the time of initial presentation with tumor, prior to any cytoreductive therapy.
  • Alternatively, patients who have recurrent disease, but who have been remotely treated (completed all antineoplastic therapy greater than or equal to one year prior to enrollment for patients who are greater than 5 years of age, or completed all antineoplastic therapy greater than 6 months prior to enrollment for patients who are less than or equal to 5 years of age), are also eligible for enrollment prior to any subsequent cytoreductive therapy.
  • Patients who have received cytoreductive therapy for Stage IV or metastatic disease may be enrolled at the time of completion of cytoreductive therapy if an apheresis specimen is available which was collected and processed prior to cytotoxic therapy according to the guidelines described in the protocol Section 3.2.2.
  • Such products will have been obtained by apheresis at the Clinical Center, National Institutes of Health (NIH), with informed consent administered as per protocol 98-C-37, 97-C-0050 or as described on standard government request form 2626 for invasive procedures.
  • Patients must be less than or equal to 35 years at the time of initial diagnosis of alveolar rhabdomyosarcoma or ESFT, weight greater than 10 kg at the time of apheresis. Patients between 10-15 kg must be approved by the apheresis unit in the Department of Transfusion Medicine (DTM) prior to enrollment on the protocol.

  • All patients or their legal guardians must give written informed consent indicating their understanding of the investigational nature and risks of the study.
  • Patients must have adequate renal function (serum creatinine (Cr) less than 1.5 mg/dl or creatinine clearance (Cr Cl), greater than 60 ml/min./1.73 m^2 and liver function (transaminases less than 3 times normal, bilirubin less than 2.0 mg/dl). Patients will not be excluded based upon abnormal hepatic function which is related to hepatic involvement by tumor.
  • For remotely treated patients, a CD4 count of greater than or equal to 400 cells/mm^3 is required.

Who cannot join

  • Women who are pregnant or lactating.
  • Patients with human immunodeficiency virus infection due to confounding effects on immune function.
  • Patients with hepatitis B or hepatitis C infection will be excluded due to the untoward risks to personnel working with blood specimens.
  • Patients who require daily oral corticosteroid therapy for any underlying disease will be excluded.
  • Topical or inhaled corticosteroids are permitted.
  • Patients who are allergic to eggs, egg products, or thimerosal, or have a history of Guillain-Barre syndrome may be enrolled on study but are ineligible to receive the influenza vaccine.

About this study

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.

Read more

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.

Read the detailed description

Eradication of low tumor burdens can occur in vivo when T-cell mediated responses are generated against specific tumor antigens. The Ewing's sarcoma family of tumors (ESFT) and alveolar rhabdomyosarcoma (AR) display several features which make them candidate diseases for trials of such immunotherapy. First, intensive cytotoxic chemotherapy is generally able to eradicate bulk disease in patients with metastatic disease, but tumor relapse eventually occurs in nearly all patients. Second, tumor-specific chromosomal translocations resulting in the production of novel fusion proteins have been identified in the great majority of these tumors. Peptides derived from these fusion proteins have been shown to function as tumor antigens for cytolytic T cells in animal studies. Third, studies of immune reconstitution after intensive cytotoxic therapy have provided evidence that antigen-specific T cells can be generated in vivo when the adoptive transfer of peripheral T cells and antigen are provided during the period of T cell regeneration. This process can be augmented in murine models by the use of human immunodeficiency virus (HIV) active protease inhibitor, indinavir, potentially through inhibition of programmed cell death in expanding T cells. Merging these concepts, this protocol will attempt to eradicate minimal residual disease in pediatric patients with metastatic ESFT and AR via vaccination with tumor-specific peptides undertaken concomitant with autologous T cell transplantation and indinavir.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Yes. Results are posted in the registry (first posted 12 Jun 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With an Immune Response to Tumor-specific and Non-tumor Specific Peptides During a Period of Immune Reconstitution (time frame: 20 weeks post vaccination). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00001566, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
