A Phase I/II Study of the Safety and Feasibility of Administering T Cells Expressing Anti-EGFRvIII Chimeric Antigen Receptor to Patients With Malignant Gliomas Expressing EGFRvIII
In Brief
A Phase 2 clinical trial evaluating Epidermal growth factor receptor(EGFRv)III Chimeric antigen receptor (CAR) transduced PBL, Aldesleukin, and 2 other interventions for Malignant Glioma and 3 related conditions. Completed, enrolled 18 participants across 1 site.
Detailed Summary
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.
