However, the following physiological replacement doses of glucocorticoids are allowed: 12 mg/m2 / dihydrogenated cortisone or equivalent; Immunosuppressive drugs: any immunosuppressive drugs must be stopped before they are selected for 4 weeks; Stop using granulocyte colony factor a week before plasmaphoresis.
• Women of childbearing age and all male subjects must agree to use effective contraceptive methods for at least 52 weeks after EGFR CAR-T infusion, and until two consecutive PCR tests show that CAR-T cells are no longer present in the body.
