Antigen-specific T Cells Against Lung Cancer

Summary

The purpose of this clinical trial is to assess the feasibility, safety and efficacy of cancer antigen-specific T cells targeting lung cancer. The cancer targeting antigens are identified through immunostaining of patient's cancer specimens. Another goal of the study is to learn more about the persistence and function of the ex vivo manipulated antigen-specific T cells in the body.
