Adoptive TKC Transfer Combined With Chemotherapy for Advanced Non-small Cell Lung Cancer (NSCLC)

• Status: Recruiting
• Trial end date: 2023-11-30
• Target enrollment: 0
• Participant gender: All

Summary

Innate immune cells are an important part of the body's innate immune system, the first line of defense against infection and cancer. Tumor killer cells (TKC) are mixed cultures of two kinds of innate immune cells, namely natural killer cells (NK cells) and gamma delta T cells (γδT cells), which are co-activated and co-cultured ex-vivo in a certain proportion by the unique TKC technology. Adoptive TKC transfer is expected to exert a strong anti-tumor effect through synergistic action between NK cells and γδT cells. In this study, the safety, tolerance, and preliminary efficacy of adoptive TKC transfer combined with chemotherapy will be examined in patients with advanced NSCLC.
