NCT01269424

Brief Summary

RATIONALE: Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. O6-benzylguanine may help temozolomide work better by making tumor cells more sensitive to the drug. Giving genetically modified peripheral blood stem cells during or after treatment may prevent side effects caused by chemotherapy. PURPOSE: This clinical trial studies O6-benzylguanine and temozolomide in combination with genetically modified peripheral blood stem cells in treating patients with newly diagnosed glioblastoma multiforme.

Outcome Measures

Primary Outcomes (1)

  • Feasibility and safety of infusing autologous P140K MGMT-transduced hematopoietic progenitors into patients with GBM

    Patients will be assessed for clinical symptoms and side-effects - CTCAE v 4.0 - from time of treatment until protocol is stopped due to toxicity, progression, patient choice, or patient election to enroll on new therapeutic option.

    up to 5 years

Secondary Outcomes (5)

  • Successful transduction rate

    up to 4 years

  • To evaluate the in vivo enrichment of P140K expressing hematopoietic cells by repeated treatments of BG and TMZ

    up to 4 years

  • Progression-free

    up to 5 years

  • Number of patients with radiological progression

    up to 5 years

  • Overall Survival

    up to 5 years

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with histologically confirmed, newly diagnosed, supratentorial GBM who have undergone gross total tumor resections or near gross total resection (resection of \>90% of enhancing tumor demonstrated by MRI) are eligible up to their third post-operative week. Patients with infratentorial disease, multifocal or leptomeningeal disease will be excluded. In general, patients will not have \> 1 cm residual measurable or evaluable disease after surgical tumor resection.
  • ECOG performance status 0-2 or Karnofsky ≥ 70.
  • Patients must have received no myelosuppressive chemotherapy prior to the diagnosis of GBM.
  • Life expectancy of at least 12 weeks.
  • Adequate hematologic (ANC ≥ 1,000/mm3, platelets ≥ 100,000/mm3, Hgb ≥ 9.5) , hepatic (Bilirubin ≤ 2.0 mg/dl, AST and ALT less than or equal to 3 times upper limit of normal, prothrombin time \<1.2 times normal), and renal (Serum creatinine ≤ 2.0 mg/dl or Creatinine Clearance ≥ 60mL/min/1.73 m2 for subjects with serum creatinine levels above institutional normal) . These tests will be repeated within 2 weeks of treatment with BG and TMZ, and must meet the same criteria.
  • EKG without evidence of acute cardiac disease.
  • Left ventricular ejection fraction (LVEF) ≥ 40
  • Post-operative steroids are tapered to ≤ 24 mg decadron/d
  • Patients of child-bearing potential must be using single barrier contraception
  • Willingness and ability to provide informed consent.
  • Patient must have all sutures removed prior to registration
  • Patient must be considered to be clinically stable.

You may not qualify if:

  • Medical condition associated with immunosuppression, active infection or medical illness which may jeopardize patient safety.
  • Pregnant or lactating women. There is data to indicate that TMZ is teratogenic and carcinogenic. Thus, its use in pregnant women would confer unnecessary risk to the fetus.
  • Patients with symptomatic pulmonary disease and other severe co-morbid conditions
  • Patients with cardiac insufficiency and an LVEF of \< 40%. History of acute coronary event disease or arrhythmia within 6 months prior to enrollment
  • Prior chemotherapy (including gliadel wafers) or hematopoietic cell transplantation.
  • Inability to undergo repeated MRI evaluation.
  • Prior diagnosis of malignant disease within a three year period with the exception of surgically cured basal cell carcinoma or carcinoma in situ of the cervix
  • Mental incapacity or psychiatric illness preventing informed consent
