Biological: CART-EGFRvIII T cells
autologous T cells that have been engineered to express an extracellular Humanized single chain antibody (scFv) with specificity for EGFRvIII linked to an intracellular signaling molecule comprised of a tandem signaling domain of the 4-1BB and TCRζ signaling modules.
humanized monoclonal immunoglobulin (Ig) G4 antibody directed against human cell surface receptor PD-1 (programmed death-1 or programmed cell death-1) with potential immune checkpoint inhibitory and antineoplastic activities.

- Number of subjects with treatment-related adverse events, using NCI CTCAE v5.0. [ Time Frame: 5 Months ]
- Overall survival Rate [ Time Frame: 15 Years ]Number of days from the date of the first CART-EGFRvIII infusion to the date of death of any cause. The survival function of OS will be calculated by the Kaplan-Meier method.
- Progression-free survival (PFS) [ Time Frame: 15 Years ]The number of days from the date of the first CART-EGFRvIII infusion to the first documented disease progression (based on standard MRI evaluation using the modified RANO criteria) or date of death, whichever occurs first. PFS will be calculated by the Kaplan-Meier method.
- Objective response rate (ORR) [ Time Frame: 15 Years ]The proportion of patients with complete response (CR) or partial response (PR) out of the total number of efficacy evaluable subjects. Exact 90%confidence interval for ORR will be computed.
