Study of CXCR5 Modified EGFE Chimeric Antigen Receptor Autologous T Cells in EGFR- Positive Patients With Advanced Non-small Cell Lung Cancer

In this study, the dose(number of cells by body weight) and time of infusion should be recorded in detail according to the dosage of slope climbing and single infusion. The safety of chimeric antigen receptor T(CAR-T) cells treatment was evaluated by observing the adverse events after cell therapy. The effectiveness of CAR-T treatment was initially assessed compared with the results of the patient's own previous standard treatment plan. Blood was collected before and within 12 months after infusion to detect the number and activity of CAR-T cells and evaluate the pharmacokinetic characteristics of CAR-T cells.
