Study of CXCR5 Modified EGFR Targeted CAR-T Cells for Advanced NSCLC

The first dose group: 0.5 × 10\^6/kg CAR positive T cells; The second dose group: 1.58 × 10\^6/ kg CAR positive T cells; The third dose group: 5 × 10\^6/kg CAR positive T cells. The above dose allows a 20 % error; For subjects with body weight greater than 60 kg, the number of cells can only be calculated according to 60 kg of body weight.
