A Phase 1 interventional study of Cyclophosphamide and PD-1 Knockout T Cells in Metastatic Non-small Cell Lung Cancer, sponsored by Sichuan University. Completed at 1 site in China. Open to participants aged 18 Years to 70 Years. Per ClinicalTrials.gov, last updated 2021-01-12.
Sponsored by Sichuan University · Phase 1, Interventional, and Treatment
This study will evaluate the safety of PD-1 knockout engineered T cells in treating metastatic non-small cell lung cancer. Blood samples will also be collected for research purposes.
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.
7,243 studies on the registry are indexed under Lung Neoplasms; 1,557 are open to participants now.
This study's enrollment of 12 is below the median of 60 across 5,295 interventional studies indexed under Lung Neoplasms.

Exclusion Criteria:
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.
