PD-1 Knockout Engineered T Cells for Metastatic Non-small Cell Lung Cancer
Metastatic Non-small Cell Lung Cancer
About this trial
This is an interventional treatment trial for Metastatic Non-small Cell Lung Cancer focused on measuring lung cancer, immune checkpoint, PD-1, CRISPR, autologous cell infusion

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.
