简要总结
Background:
The National Cancer Institute (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 epidermal growth factor receptor (EGFR) vIII 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 National Institutes of Health (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.
详细描述
BACKGROUND:
- Patients with recurrent gliomas have very limited treatment options. Epidermal growth factor receptor (EGFR).
(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.

结局指标
主要结局
Number of Treatment Related Adverse Events
时间窗: From 4 weeks after cell infusion up to 77 days
Aggregate of all adverse events ≥Grade 3 that are possibly, probably, and definitely related to treatment. Adverse events were assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0). Per CTCAE, Grade 3 adverse events are severe, Grade 4 is life threatening, and Grade 5 is death.
Progression Free Survival
时间窗: Time from the date of registration to the date of first observation of progressive disease up to 6 months after end of treatment
Progression was assessed by the Response Assessment in Neuro-Oncology (RANO) criteria and is defined as the circumstance when the magnetic resonance imaging (MRI) scan is ranked -2 (definitely worse) or -3 (development of a new lesion).
次要结局
- Number of Patients With an Objective Response(4 weeks after cell infusion and monthly as feasible up to 12 months)
- Circulating Chimeric Antigen Receptor (CAR+) Cells in Peripheral Blood at 1 Month Post Treatment(1 month post transplant)
- Number of Participants With Serious and Non-serious Adverse Events Assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0)(51 dys Grp A, Cohort 1; Cohort 2:68 dys; Cohort 3:40 dys; Grp B, Cohort 1:67 dys; Cohort 2:48 dys; Cohort 3:55 dys; Cohort 4: 46 dys; Cohort 5:147 dys; C.
