Brief Summary:

Background:

The NCI Surgery Branch has developed an experimental therapy for treating patients with gliomas that involves taking white blood cells from the patient, growing them in the laboratory in large numbers, genetically modifying these specific cells with a type of virus (retrovirus) to attack only the tumor cells, and then giving the cells back to the patient. This type of therapy is called gene transfer. In this protocol, we are modifying the patient s white blood cells with a retrovirus that has the gene for anti-EGFRvIII incorporated in the retrovirus.

Objective:

The purpose of this study is to determine a safe number of these cells to infuse and to see if these particular tumor-fighting cells (anti-EGFRvIII cells) are a safe and effective treatment for advanced gliomas.

Eligibility:

- Adults age 18-70 with malignant glioma expressing the EGFRvIII molecule.

Design:

Work up stage: Patients will be seen as an outpatient at the NIH clinical Center and undergo a history and physical examination, scans, x-rays, lab tests, and other tests as needed

Leukapheresis: If the patients meet all of the requirements for the study they will undergo leukapheresis to obtain white blood cells to make the anti-EGFRvIII cells. {Leukapheresis is a common procedure, which removes only the white blood cells from the patient.}

Treatment: Once their cells have grown, the patients will be admitted to the hospital for the conditioning chemotherapy, the anti-EGFRvIII cells, and aldesleukin. They will stay in the hospital for about 4 weeks for the treatment.

Follow up: Patients will return to the clinic for a physical exam, review of side effects, lab tests, and scans every month for the first year, and then every 1-2 months as long as their tumors are shrinking. Follow up visits will take up to 2 days.

Malignant Glioma Glioblastoma Brain Cancer Gliosarcoma Biological: Anti-EGFRvIII CAR transduced PBL Drug: Aldesleukin Drug: Fludarabine Drug: Cyclophosphamide Phase 1 Phase 2

Detailed Description:

BACKGROUND:

- Patients with recurrent gliomas have very limited treatment options. EGFR variant III

(EGFRvIII) is the most common mutant variant of EGFR and is present in 24-67% of patients with glioblastoma.

  • EGFRvIII expression promotes oncogenesis and is associated with poor prognosis.
  • EGFRvIII is not expressed in normal tissue and is an attractive target for immunotherapy.
  • We have constructed a retroviral vector that contains a chimeric antigen receptor (CAR) that recognizes the EGFRvIII tumor antigen, which can be used to mediate genetic transfer of this CAR with high efficiency without the need to perform any selection.

OBJECTIVES:

Primary Objectives

  • To evaluate the safety of the administration of anti-EGFRvIII CAR engineered peripheral blood lymphocytes in patients receiving the non-myeloablative, lymphodepleting preparative regimen and aldesleukin.
  • Determine the six month progression free survival of patients receiving anti-EGFRvIII CAR-engineered peripheral blood lymphocytes and aldesleukin following a nonmyeloablative, lymphodepleting preparative regimen.

ELIGIBILITY:

  • Histologically proven glioblastoma or gliosarcoma expressing EGFRvIII as determined by IHC or RT-PCR
  • Failed prior standard treatment with radiotherapy with or without chemotherapy
  • Karnofsky performance score (KPS) greater than or equal to 60
  • Cardiac, pulmonary and laboratory parameters within acceptable limits

DESIGN:

  • The study will be conducted using a Phase I/II design.
  • Patients will receive a non-myeloablative, lymphodepleting preparative regimen consisting of cyclophosphamide and fludarabine followed by intravenous infusion of ex vivo tumorreactive, CAR gene-transduced PBMC, plus IV aldesleukin.
  • Once the maximum tolerated cell dose (MTD) has been determined, the study will proceed to the phase II portion.
  • In the phase II portion of the trial, patients will be accrued to two cohorts:

    • Patients with recurrent malignant glioma receiving steroids at the time of treatment.
    • Patients with recurrent malignant glioma not receiving steroids at the time of treatment.
  • A total of 107 patients may be enrolled over a period of 7 years.

  2. Patients must have progression of disease after radiotherapy (including patients that undergo surgery for recurrent disease and are rendered NED). This includes recurrent GBM after receiving all standard first-line treatment, including surgery (if feasible due to neurosurgical and neuro-anatomical considerations) and adjuvant radiotherapy +/- chemotherapy.
  3. Patients must either not be receiving steroids, or be on a stable dose of steroids for at least five days prior to registration.
