Non-small cell lung cancer is the most common kind of lung cancer accounting for 80-85% of lung cancers, It is a disease in which malignant (cancer) cells form in the tissues of the lung. People who smoke or who breathe a lot of smoke are most likely to get NSCLC. Many of them are over 65.

This is a dose-escalation study of ex-vivo knocked-out, expanded, and selected PD-1 knockout-T cells from autologous origin. Patients are assigned to 1 of 3 treatment groups to determine the maximal tolerant dose. After the lower number of cycles are considered tolerant, an arm of the next higher number of cycles will be open to next patients. Biomarkers and immunological markers are collected and analyzed as well.
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.
