BG & TMZ Therapy of Glioblastoma Multiforme

Registration Number
NCT01269424
Lead Sponsor
Stanton Gerson MD
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 treat...

Detailed Description

OBJECTIVES:

Primary

* To evaluate the feasibility of introducing and expressing P140K MGMT cDNA from a lentiviral-based provirus in autologous hematopoietic stem cells harvested from Glioblastoma multiforme (GBM) patients.

Inclusion Criteria
  • 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.

Exclusion criteria:

  • Medical condition associated with immunosuppression, active infection or medical illness which may jeopardize patient safety.
  • HIV seropositivity. This exclusion is included for two reasons. First, there is evidence of decreased marrow reserve in HIV+ patients and antiviral treatment is associated with myelosuppression. Thus, drug treatment designed to be myelosuppressive may be more toxic in this patient population. Second, extensive laboratory culturing of the bone marrow and peripheral blood progenitor cells is required. No preclinical samples which are HIV+ have been evaluated with the gene transfer modality proposed and thus the feasibility and safety of gene transfer and selection in HIV+ samples cannot yet be advocated. Such studies are planned so as to not preclude HIV+ patients in later studies.
  • 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

Primary Outcome Measures
NameTimeMethod
Feasibility and safety of infusing autologous P140K MGMT-transduced hematopoietic progenitors into patients with GBMup to 5 years

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.

Secondary Outcome Measures
NameTimeMethod
