|Glioblastoma Gliosarcoma||Radiation: 3-Dimensional Conformal Radiation Therapy Procedure: Autologous Hematopoietic Stem Cell Transplantation Drug: Carmustine Biological: Filgrastim Procedure: In Vitro-Treated Peripheral Blood Stem Cell Transplantation Radiation: Intensity-Modulated Radiation Therapy Other: Laboratory Biomarker Analysis Drug: O6-Benzylguanine Drug: Plerixafor Radiation: Proton Beam Radiation Therapy Drug: Temozolomide||Phase 1 Phase 2|
I. Determine the safety and feasibility of infusing autologous granulocyte colony-stimulating factor (G-CSF) (filgrastim) mobilized stem cells transduced with a Phoenix-gibbon ape leukemia virus (GALV)-pseudotype vector expressing methylguanine methyltransferase (MGMT) (P140K).
II. Define the dose of BCNU (carmustine) that results in efficient engraftment of gene modified cells when given with peripheral blood stem cell support.
I. Determine the engraftment of gene-modified cells after conditioning with BCNU.
II. Determine the ability to select gene-modified cells in vivo with this regimen.
III. Evaluate the molecular and clonal composition of gene-modified cells after chemotherapy with temozolomide.
IV. Observe patients for clinical anti-tumor response.
V. Determine the correlation of the level of MGMT (P140K) marking with toxicity, temozolomide dose achieved, and response.
VI. Characterize the toxicity associated with this regimen.
OUTLINE: This is a phase I, dose-escalation study of temozolomide followed by a phase II study.
PART I: Within 35 days of surgery, patients undergo 3 dimensional (3D) conformal intensity-modulated radiation therapy (IMRT) or proton beam radiation therapy daily 5 days per week for 6 weeks. Patients receive filgrastim subcutaneously (SC) on days -7 to -3 and begin stem cell collection on the 4th day of filgrastim administration (up to 3 apheresis). Patients may also receive plerixafor SC on days -5 to -3. The CD34+ stem cells are separated from the patient's stem cells and they are transduced with Phoenix-RD114 pseudotype vector (retrovirus). One day after apheresis is completed, patients receive carmustine intravenously (IV) over 3 hours followed 2 hours later by temozolomide orally (PO). At least twenty-four hours after completion of carmustine and temozolomide, patients undergo reinfusion of genetically-modified stem cells.
PART II: Beginning approximately 4 weeks after completion of Phase 1 of the study, patients receive O6-benzylguanine IV continuously over 48 hours followed by temozolomide PO within 1 hour. Treatment may repeat at least every 28 days for a total of 24 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed every 1-3 months for 2 years, every 3-6 months for 3 years, and then annually thereafter for 10 years.

- Number of Participants Dose-limiting Toxicity (DLT) [ Time Frame: Up to 6 weeks after infusion ]Defined as any grade 4 nonhematopoietic toxicity that is likely related to the investigational procedures (Part I)
- Number of Participants With Retrovirus or Leukemia [ Time Frame: Up to 2 years after infusion ]Replication competent retrovirus or diagnosis of leukemia
- Response Rate [ Time Frame: Up to 66 months ]Number of patients with reduction in tumor burden of a predefined amount
- Duration of Response [ Time Frame: Up to 65 months ]From the onset of temozolomide to the date at which unequivocal disease progression, assessed up to 65 months.
- Time to Progression [ Time Frame: Up to 66 months. ]From the first day of treatment (transplant) until unequivocal progression is documented, assessed up to 66 months.
- Number of Participants That Survived [ Time Frame: Up to 74 months ]From the first day of treatment until death, assessed up to 74 months.
- Number of Participants With Chemoprotection [ Time Frame: Up to 66 months ]assessed by the ability to increase the Temozolomide dose beyond 472 mg/m^2
- Number of Participants With Chemoselection [ Time Frame: Up to 59 months ]assessed by the increase in peripheral blood Vector Copy Number (VCN), the average copies of integrated transgene per cell, after chemotherapy
- Gene Transfer Efficiency [ Time Frame: Up to 59 months ]Assessed by gene marking in peripheral blood prior to chemoselection. Gene marking is assessed in whole blood by quantitative PCR and reported as a vector copy number (VCN) or the average copies of integrated transgene per cell. The units here will be reported as copies/cell.
- Gene Transfer Efficiency After Chemotherapy [ Time Frame: Up to 59 months ]Assessed by gene marking in peripheral blood after chemoselection. Gene marking is assessed in whole blood by quantitative PCR and reported as a vector copy number (VCN) or the average copies of integrated transgene per cell. The units here will be reported as copies/cell.
