Genetically Engineered Cells (COH06) With or Without Atezolizumab for the Treatment of Non-small Cell Lung Cancer Previously Treated With PD-1 and/or PD-L1 Immune Checkpoint Inhibitors

• Status: Not yet recruiting
• Trial end date: 2025-01-28
• Target enrollment: 0
• Participant gender: All

Summary

This phase I trial studies the side effects and best dose of COH06 with or without atezolizumab in patients with non-small cell lung cancer previously treated with PD-1 and/or PD-L1 immune checkpoint inhibitors that has spread to other places in the body (advanced) and that has not responded to previous treatment (refractory). NK cells are infection fighting blood cells that can kill tumor cells. The NK cells given in this study, COH06, will come from umbilical cord blood and will have a new gene put in them that makes them express PD-L1, and express and secrete IL-15. NK cells that express PD-L1 may kill more tumor cells, and IL-15 may allow the NK cells to live longer. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving COH06 without or without atezolizumab may help control the disease in patients with non-small cell lung cancer.
