Brief Summary:

Immunotherapy is a specific approach to treating cancer that has shown promise in adult patients for the treatment of melanoma, malignant brain tumors, and other cancers. The study investigators will use the experience they have gained from these studies to try to improve the outcome for children affected by a recurrent brain tumor.

This study will have two phases.

During Phase I, approximately 9 patients will be treated with increasing doses of tumor-specific immune cells to determine the safety of this treatment. Phase I patients will also receive dendritic cell vaccines to help boost the function of these immune cells and maintain their growth.

During Phase II, approximately 35 patients will be treated with tumor-specific immune cells and dendritic cell vaccines to see what impact they have on the tumor.

Detailed Description:

Malignant brain tumors now represent the most frequent cause of cancer death in children. Despite aggressive and highly toxic multi-modality therapy including surgery, craniospinal radiation, and high-dose chemotherapy coupled with peripheral blood stem cell transplantation, almost half the children diagnosed with the most common malignant brain tumors, medulloblastoma (MB) and primitive neuroectodermal tumors (PNET), will still die from recurrent disease. Furthermore, survivors are often left with severe and lifelong treatment-associated cognitive and motor deficits. The development of more effective and tumor-specific therapies that will not add further toxicity to existing treatments is paramount in improving clinical outcomes for children affected by MB/PNETs. Immunotherapy targeting tumor-specific antigens expressed within brain tumors is a modality potentially capable of meeting this clear and urgent need.

Despite considerable advancements and promising clinical results observed in immunotherapy trials directed against adult malignant brain tumors, efforts in the immunologic treatment of pediatric brain tumors have been limited to relatively few notable studies. This is due, at least in part, to the often limited viable tumor tissue available for tumor cell-based vaccine preparations, and the lack of identification of consistently expressed tumor-specific antigens within these cancers.

The use of total tumor RNA (TTRNA)-loaded dendritic cells (DCs) was pioneered at Duke University, as a novel platform for inducing potent immunologic responses against the variety of uncharacterized and patient-specific antigens present within malignant tumor cells. Duke demonstrated that sufficient RNA for clinical vaccine preparations can be amplified with high fidelity using existing molecular technologies from as few as 500 isolated pediatric and adult brain tumor cells, thus allowing vaccine preparation from surgical biopsies and even microdissected archival tumor specimens. In this study, the investigators will treat recurrent MB/PNETs during hematopoietic recovery from chemotherapy.

Immunotherapy administered during recovery from chemotherapy may have tremendous advantages, as adoptive cellular therapy following lymphodepletive conditioning regimens has emerged as the most effective treatment strategy for advanced and refractory melanoma. Our hypothesis is that DC + ex vivo expanded Autologous Lymphocyte Transfer (xALT) therapy targeting recurrent MB/PNETs during recovery from myeloablative chemotherapy will be safe and will prolong survival in children and young adults with recurrent MB/PNETs.

Layout table for eligibility information
Ages Eligible for Study:   up to 30 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:


  • Age ≤ 30 years of age.
  • Suspected first recurrence/progression of MB/PNET since completion of definitive focal +/- craniospinal irradiation. Disease progression prior to receiving definitive focal +/- craniospinal irradiation will not disqualify patients from enrollment if they have subsequently failed definitive radiotherapy and are at first recurrence/progression at time of enrollment. Patients who are unable to receive radiation therapy due to genetic disorders that put them at significant risk for radiation-induced secondary malignancies (i.e. Gorlin's syndrome or NF1 mutation) are eligible for enrollment at first disease recurrence/progression.

Re-MATCH Protocol:

  • Patients must have histologically confirmed recurrent MB/PNET that is a first relapse/progression after completion of definitive radiotherapy +/- craniospinal irradiation. Patients with a first relapse/progression who are unable to receive radiation therapy due to genetic disorders that put them at significant risk for radiation-induced secondary malignancies (ie. Gorlin's syndrome or NF1 mutation) are eligible for enrollment.
  • Patients with neurological deficits should have deficits that are stable for a minimum of 1 week prior to registration.
  • Karnofsky Performance Status of ≥ 50% or Lansky Performance Score of ≥ 50.
  • Absolute Neutrophil Count (ANC) ≥ 1000/µl (unsupported).
  • Platelets ≥ 100,000/µl (unsupported).
  • Hemoglobin > 8 g/dL (may be supported).
  • Serum creatinine ≤ upper limit of institutional normal
  • Bilirubin ≤ 1.5 times upper limit of normal for age.
  • Serum Glutamic Oxaloacetic Transaminase (ALT) ≤ 3 times institutional upper limit of normal for age.
  • Serum Glutamic Oxaloacetic Transaminase (AST) ≤ 3 times institutional upper limit of normal for age.

  • Patient or patient guardian consent to peripheral blood stem cell (PBSC) and/or bone marrow harvest following registration if PBSC or bone marrow (CD34 count of at least 2x10^6/kg) has not been previously stored and available for use.
  • Signed informed consent according to institutional guidelines must be obtained prior to registration.

  • Patients receiving concomitant immunosuppressive agents for medical condition.
  • Patients who need definitive radiotherapy for treatment of recurrent MB/PNET. Focal boost radiotherapy may be delivered prior to immunotherapy if required for local control.
  • Patients receiving any other concurrent anticancer or investigational drug therapy.
