Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
A - Two cycles
Peripheral blood lymphocytes will be collected and Programmed cell death protein 1(PDCD1) gene will be knocked out by CRISPR Cas9 in the laboratory (PD-1 Knockout T cells). The lymphocytes will be selected and expanded ex vivo and infused back into patients. Cyclophosphamide at 20mg/kg single dose will be administered 3 days i.v. before cell infusion.
A total of 1 x 10\^7/kg PD-1 Knockout T cells will be infused in one cycle. Each cycle is divided into three administrations, with 20% infused in the first administration, 30% in the second, and the remaining 50% in the third. Patients will receive a total of two cycles of treatment.
Cyclophosphamide
To deplete Tregs before collecting peripheral blood
PD-1 Knockout T Cells
Autologous lymphocytes are collected and PDCD1 gene is knocked out in the laboratory. Cells are selected and expanded ex vivo. Cells are infused back to the patients for treatment
B- Two cycles
Peripheral blood lymphocytes will be collected and Programmed cell death protein 1(PDCD1) gene will be knocked out by CRISPR Cas9 in the laboratory (PD-1 Knockout T cells). The lymphocytes will be selected and expanded ex vivo and infused back into patients. Cyclophosphamide at 20mg/kg single dose will be administered 3 days i.v. before cell infusion.
A total of 2 x 10\^7/kg PD-1 Knockout T cells will be infused in one cycle. Each cycle is divided into three administrations, with 20% infused in the first administration, 30% in the second, and the remaining 50% in the third. Patients will receive a total of two cycles of treatment.

The lymphocytes will be selected and expanded ex vivo and infused back into patients. Cyclophosphamide at 20mg/kg single dose will be administered 3 days i.v. before cell infusion.
A total of 4 x 10\^7/kg PD-1 Knockout T cells will be infused in one cycle. Each cycle is divided into three administrations, with 20% infused in the first administration, 30% in the second, and the remaining 50% in the third. Patients will receive a total of two cycles of treatment.
