Brief Summary:
Adult patients who have surgical resection of newly diagnosed glioblastoma multiforme will be treated with radiotherapy/chemotherapy followed by dendritic cell vaccine. Chemotherapy will be administered after three vaccinations for one year or until progression of disease.

Condition or disease Intervention/treatment Phase
Glioblastoma Multiforme Biological: Autologous Dendritic Cell Drug: Temozolomide Procedure: Radiotherapy Biological: Dendritic Cell Vaccine Phase 2

Detailed Description:
Two to six weeks after surgery, patients with newly diagnosed glioblastoma multiforme (GBM) will undergo a six-week course of radiotherapy with concurrent chemotherapy (temozolomide). Between three and seven weeks after completing radiotherapy/chemotherapy, patients will undergo leukapheresis to collect white blood cells. These cells will be grown into dendritic cells, and cultured with tumor cells from the individual patient. Vaccinations will be given every two weeks for a total of three vaccinations. Four weeks after the third vaccination patients will resume chemotherapy for one year or until disease progression.

Arm Intervention/treatment
Experimental: Vaccine Biological: Autologous Dendritic Cell
Vaccine given by cervical lymph node injection 3 times every other week

Drug: Temozolomide
Radiotherapy (RT) with concurrent temozolomide (TMZ) for 6 weeks before vaccine is SOC

Procedure: Radiotherapy
RT is standard of care (SOC) post surgery

Biological: Dendritic Cell Vaccine
Vaccine given cervical lymphnode injection 3 times every other week




Primary Outcome Measures :
  1. Tumor-specific Cytotoxic T-cell Response [ Time Frame: Day 42 ]
    MRI & pheresis post vaccine


Secondary Outcome Measures :
  1. Number of Adverse Events: Toxicity Profile of Intra-nodal DC/Tumor Lysate Vaccination [ Time Frame: Until death or approximately 24 months after diagnosis ]
    Adverse events attributed to vaccination. Collected and attributed adverse events at each study visit; monitored participants for adverse events for two hours following vaccination procedure.

  2. Number of Participants With Evaluable Data: Feasibility of Vaccination [ Time Frame: Through enrollment, approximately 2 years ]
    To determine the feasibility of this approach, the investigators hypothesize that at least 2/3 of the patients included in the study will be evaluable, meaning that the participants would have received the 3 vaccinations with immunologic outcome parameters measured before and after vaccination. Therefore a maximum of 15 patients would be enrolled in the study to obtain 10 evaluable patients. If after enrolling 15 patients the investigators are unable to obtain 10 evaluable patients, the investigators would consider this approach not feasible.

  3. Progression Free Survival (PFS) [ Time Frame: Approximately 42 months ]
    Progression-free survival will be assessed for each patient as the time from surgery until the patient reaches objective disease progression by MRI criteria. Death will be regarded as a progression event in those patients that die before disease progression. Patients without documented objective progression at the time of the analysis will be censored at the date of their last objective tumor assessment. Since disease free survival and overall survival are secondary endpoints all patients will be followed until death or for a period of 5 years following enrollment.

  4. Number of Participants With Significant Difference in Tumor Volume Size Pre- and Postvaccination: Neuroimaging and Tumor Assessment [ Time Frame: baseline and 4 weeks ]
    Patients with evidence of evaluable enhancing disease on contrast-enhanced MRI performed within four weeks of study entry will be evaluated for response rate. Patients will be evaluated for objective tumor assessments by gadolinium-enhanced magnetic resonance imaging (Gd-MRI). Comparisons of objective assessments, excluding progressive disease, are based upon major changes in tumor size on the Gd-MRI compared to the baseline scan. Determination of progressive disease is based upon comparison to the previous scan with volumetric analysis.

  5. Overall Survival Duration: Efficacy Parameters [ Time Frame: Approximately 42 months ]
    Overall survival will also be followed. Survival will be assessed from the date of surgery to the date of patient death, due to any cause, or to the last date the patient was known to be alive.

  6. Frequency of CD4+ and CD8+ T Cells - the Proportion of Cells in the Parent Population Responding to Glioblastoma Multiforme (GBM) - Median [ Time Frame: Day 7 (pre-vaccination) and Day 42 (post-vaccination). ]
    Pre- and post-vaccine immune assay results (Tumor-specific T-cells ) are summarized on a continuous scale as median.

  7. Percentage of Tumor-specific T-cells - Correlation Between Immunological Parameters and Efficacy- Median [ Time Frame: Day 7 (pre-vaccination) and Day 42 (post-vaccination) ]
    Pre- and post-vaccine immune assay results (Tumor-specific T-cell Responses) are summarized on a continuous scale as median.

  8. Number of Enzyme-linked Immunosorbent Spots (ELISPOT) - Correlation Between Immunological Parameters and Efficacy - Median [ Time Frame: Day 7 (pre-vaccination) and Day 42 (post-vaccination) ]
    Pre- and post-vaccine immune assay results (Tumor-specific T-cell Responses) are summarized on a continuous scale as mean.

  9. Frequency of CD4+ and CD8+ T Cells - the Proportion of Cells in the Parent Population Responding to Glioblastoma Multiforme (GBM) - Mean [ Time Frame: Day 7 (pre-vaccination) and Day 42 (post-vaccination) ]
    Pre- and post-vaccine immune assay results (Tumor-specific T-cells ) are summarized on a continuous scale as mean.

  10. Percentage of Tumor-specific T-cells - Correlation Between Immunological Parameters and Efficacy- Mean [ Time Frame: Day 7 (pre-vaccination) and Day 42 (post-vaccination) ]
    Pre- and post-vaccine immune assay results (Tumor-specific T-cell Responses) are summarized on a continuous scale as median. IFN = interferon.

  11. Number of Enzyme-linked Immunosorbent Spots (ELISPOT) - Correlation Between Immunological Parameters and Efficacy - Mean [ Time Frame: Day 7 (pre-vaccination) and Day 42 (post-vaccination) ]
    Pre- and post-vaccine immune assay results (Tumor-specific T-cell Responses) are summarized on a continuous scale as mean.

  12. Evaluation of T Cell Characteristics [ Time Frame: Before starting radiation/Temozolomide and at Day 7 and Day 42. ]
    Peripheral blood obtained before starting radiation/ temozolomide (TMZ), and at first and second leukapheresis will be used to do lymphocyte phenotyping. We will determine percentages of CD3+/CD8+/CD45RO+ (memory T-cells), CD3+/CD8+/CD28- (CD8 suppressor T cell phenotype), and CD4+/CD25+ cells at those 3 time points. An anti-human Foxp3 antibody will be used to determine if the CD4+/CD25+ cells are T regulatory cells (TREG) and how the compartmental shift correlates with immunoresponse by other immune parameters as well as to efficacy.

  13. Immunohistochemistry [ Time Frame: Approximately 42 months ]

    Pathologic specimen obtained from patients who require of another surgical resection after vaccination will be examined to determine the characteristics of infiltrating tumor cells.

    Paraffin sections of tumor specimen will be stained by immunohistochemistry with antibodies to identify the components of the inflammatory response. This specimen will be compared to the one obtained at the time of initial surgery and changes in inflammation and inflammatory cellular components will be noted.
