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.

Approximately 35 patients with first recurrence of medulloblastoma (reMB)/supratentorial primitive neuroectodermal tumors (PNETs) will be treated with tumor-specific immune cells and dendritic cell vaccines to see what impact they have on the tumor.

Medulloblastoma Neuroectodermal Tumor Biological: TTRNA-xALT Biological: TTRNA-DCs Phase 2

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.

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.

In this study, the investigators will treat patients with first recurrence reMB/PNETs after completion of definitive radiation therapy with autologous tumor-specific T cell immunotherapy (TTRNA-xALT) plus TTRNA-loaded dendritic cell vaccine.

Following surgical resection, biopsy, or cytology examination with confirmatory pathologic diagnosis, patients will be enrolled into Group A (high-dose chemotherapy or HDC) or Group B (non-myeloablative or NMA salvage chemotherapy) based on eligibility for HDC. Patients with localized relapse and have not failed HDC+ peripheral blood stem cell transplant (PBSCT) previously will be enrolled into Group A. Patients with disseminated disease, have previously failed HDC+PBSCT, or are otherwise considered poor candidates for HDC based on overall health status, but otherwise meet eligibility criteria, will be enrolled into Group B. All patients will receive DC + xALT therapy.

Primary Outcome Measures :
  1. 12 Month Progression-free Survival (PFS-12) [ Time Frame: up to 12 months ]
    PFS is defined as time interval from date of first DC vaccine to date of progression (death is also treated as progression) or censoring, whichever happens first.


Secondary Outcome Measures :
  1. Objective Radiographic Response Rate [ Time Frame: best overall radiographic response through duration on study (up to 60 months) ]
    Radiographic response will be assessed as a percentage change in tumor size from pre-treatment (baseline) MRI scans of the brain and spine obtained with and without contrast. Evaluation will be based on the NCI-endorsed, World Health Organization RECIST criteria and using a modified version of the MacDonald criteria (complete response, partial response, stable disease, progressive disease or not assessible).

  2. Correlate Magnitude and Persistence of Anti-tumor Humoral or Cellular Immunity With Clinical Outcome [ Time Frame: baseline compared to 6 weeks post vaccine #1 and longitudinal measures through overall survival (up to 60 months) ]
    Peripheral blood will be used to compare pre-therapy lymphocyte function to defined intervals after each immunization. Blood will be obtained for immunologic monitoring prior to non-mobilized leukapheresis, prior to immunotherapy, 1 day post Vaccine #1, 4 (+/- 1) days post Vaccine #1, weekly post Vaccine #1 for six weeks.

  3. Evaluate Changes in Cytokine Profile and Toll-Like Receptor Activation Status [ Time Frame: baseline compared to 6 weeks post vaccine #1 and longitudinal measures through overall survival (up to 60 months) ]
    We will measure serum cytokines pre and post therapy. Blood will be obtained for immunologic monitoring prior to non-mobilized leukapheresis, prior to immunotherapy, 1 day post Vaccine #1, 4 (+/- 1) days post Vaccine #1, weekly post Vaccine #1 for six weeks.

  4. Characterize Immunologic Phenotype of Lymphocyte Subsets and NK Cells [ Time Frame: baseline compared to 6 weeks post vaccine #1 and longitudinal measures through overall survival (up to 60 months) ]
    We will conduct flow cytometry from patient samples. Blood will be obtained for immunologic monitoring prior to non-mobilized leukapheresis, prior to immunotherapy, 1 day post Vaccine #1, 4 (+/- 1) days post Vaccine #1, weekly post Vaccine #1 for six weeks.

  5. Determine of Overall Survival Rate [ Time Frame: up to 60 months ]
    Kaplan-Meier estimator will be used to describe length of overall survival from initiation of vaccine #1 for both Groups A and B.

Inclusion Criteria:

Screening:

  • 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.
