TCR-T Cell Therapy on Advanced Solid Tumors

The primary aim of this study is to evaluate the efficacy of KRAS mutant antigen specific TCR-T cells in the treatment of patients with advanced solid tumors. The secondary aim is to evaluate the pharmacokinetic/pharmacodynamic characteristics of TCR-T cell therapy in patients with advanced solid tumors and the survival of TCR-T cells. The investigators will evaluate the changes of tumor microenvironment after treatment of advanced solid tumors with KRAS mutant antigen specific TCR-T cells; Evaluating the correlation between cytokines and the occurrence of CRS and neurotoxicity
